My Zope Zen seem to have gone negative (started at zero - and just got worse
:( ) but HOW do you install it.  I could find no mention of any "lever"s in
the ZMG.pdf,
and I have tried as many ways as I could think of to get my Zope (1.10.2 on
ZAP) to read/import the FAQ product, but no cigar - not even close!

Where does one put which files, and what procedure does one go through to
invoke said "Lever" functionality.  Sorry about this, but surely I can't be
the *only* one that is totally lost.  (Come to think of it, maybe I can!)

It certainly looks like you are having a problem, but since I developed to
FAQ Tool under win32 and it works fine for me under Linux, I don't agree
with you assessment of the problem. Would you please file a bug report in
the collector including this traceback. This is getting deeper than I can
easily troubleshoot.

Message-ID: <010201be63c8$48369be0$147800a0@pc-pi0>

Hello,

I want to *add* content to the default standard_html_header in a subfolder
that we call, say, SF. The standard_html_header in SF reads:

<!--#var standard_html_header-->
<!-- other content-->

But since an object acquire from itself, this did not work (infinite
traceback,
obviously because the stack is filled with recursive calls)
So I wrote:

<!--#with aq_parent--><!--#var standard_html_header--><!--#/with>
<!-- other content-->

And it works for object accessed within SF. But when I create sub-folder
*under*
SF, say SSF, I end up with an error.

How could i write this?

I assume this means Zope will also appear in the Application Server list of

I meant, doing the equivalent (catching exceptions) not implementing the same

I got it working using the following code:
<!--#with "PARENTS[-1]"--><!--#var standard_html_header--><!--#/with-->
<!-- other content -->

This only works when this code is in a sub-Folder, and the standard_html_header
can be found in the root folder.

Does python have anything equivalent to Perl's taint mode? Because if it does
then this could be used. That and restricting allowable APIs from internal
methods - again, if this is possible.

Well, I found that standard_html_header were called several times, and
that's what caused the error.
Let SF/standard_html_header be:

--------8<--------
<!--#with aq_parent--><!--#var standard_html_header--><!--#/with-->
Hello!
--------8<--------

Then, when I access http://mysite/SF, I get:

--------8<--------
[pretty standard_html_header]
Hello! Hello!
This is the index_html document in SF.
--------8<--------

Why is Hello! printed twice???
From SSF, I get Hello! printed 3 times...

EGroups archives the mailinglist. At http://www.egroups.com/lists/zope you can
find a search interface, which quite often actually works.

Message-ID: <19990301132234.A682@RaVER.duck.org>

Hi all!

I know the question has been up to debate earlier on the list, but still...

I can't get Apache to send authorization headers on to Zope - even tough
I've tried to do what the doc/WEBSERVER.txt tells me to (tried both rewrite
and to let apache authenticate /cgi-bin/Zope/). I also grabbed the
latest Zap release, but that one din't work (broken?). Also had a look at
the zap.conf file and tried using some in my httpd.conf file, but I still
had no luck. 

Now - here is my current config:

Linux 2.0.35
Python 1.5.1
Zope 1.10.2
Apache 1.3.4

Something there that doesn't play well together?

If not - what is wrong??

Appreciate all the help I can get!

This may sound like a bit of an obvious suggestion, but it caught me out.

Check the Directory directive for <apacheroot>/cgi-bin and make sure that
the ExecCGI option is set.

It should look something like this:

<Directory "/www/cgi-bin">
    AllowOverride none
    Options ExecCGi
    Order allow,deny
    Allow from all
</Directory>

Apache 1.3.4 by default doesn't have the ExecCGI option set.

I don't get a traceback because I didn't "fiddle", the FAQ item shows up 
in the control panel, but is not in the Add drop-down.

I'm running 1.10.2 on NT with ZServer.

The 'fiddling' involves disbling the exception handling of the product
initialisation. Normally, a 'Levered' product, that has been distributed, has a
product.dat file. This file contains the compressed pickled reprensentation of
the product, which basicly consists of other Zope objects, with a Principia
Factory.

When Zope can't uncompress and depickle the product.dat file, you only get to
see that the Product is installed, but it doesn't contain anything (which a
Levered Product actually should), and nothing else happens or can happen. If
you want to know more on how to use the 'Lever', read up at
http://www.zope.org/Documentation/Guides/ZMG/ZMG-HTML/ZMG.html#pgfId-986684
(Zope Manager's Guide, Creating Zoipe Products).

When you disable the exception handling in initializeProduct in Product.py, and
restart Zope, it will exit with the traceback I reported.

I have reported this to DC with the Collector, but I used Win98. You are using
WinNT, which is interesting.. Something goes wrong with decompressing the
product.dat file on win32 platforms (Amos says he tested it succesfully on
Linux).

I don't want to get into a language war, but as someone who lives and
breathes security, taint mode is a joke.  Python's rexec module would be
great (as would Bastion), but this is going to require a much higher
level of ZopeZen to implement than I currently have.  Yes I know my
proposal was wrought with huge security problems, but regardless it is
valuable to a some people in the near term (such as those of us on the
STarship).

BTW, requiring write access to the file system is only trivially more
secure.

Unfortunately the ExecCGI option didn't help much. Thanks anyways. 

I'm still stuck at the
point where I get 'Authorization failed'. I've checked and double checked my
Zope/access file and I use correct username and passwd. The filepermissions
should also be set correct (according to the instructions given in the
INSTALL.txt file). Problem is, as far as I can tell, connected to the way
the rewrite module does the rewrite....

Has anyone confirmed that the way the WEBSERVER.txt file says to rewrite the
authorization header actually works?

If it works - is there someone that can say exactly how apache should be
configured and compiled to get it working (best of all also put in a working
httpd.conf also)?

And again.....Appreciate all teh help I can get!

We'd prefer that you start with the Zap distribution, as it removes a
whole bunch of variables.  Can you tell us what was the error with using
Zap?

Well the WEBSERVER.txt instructions work for me.

Find attached a working httpd.conf.

Also attahced is a module listing from my 'httpd'.

##=0A=
=0A=
#=0A=
# Based upon the NCSA server configuration files originally by Rob =

#=0A=
# This is the main Apache server configuration file.  It contains the=0A=
# configuration directives that give the server its instructions.=0A=
# See <URL:http://www.apache.org/docs/> for detailed information about=0A=
# the directives.=0A=
#=0A=
# Do NOT simply read the instructions in here without understanding=0A=
# what they do.  They're here only as hints or reminders.  If you are =
unsure=0A=
# consult the online docs. You have been warned.  =0A=
#=0A=
# After this file is processed, the server will look for and process=0A=
# /www/conf/srm.conf and then /www/conf/access.conf=0A=
# unless you have overridden these with ResourceConfig and/or=0A=
# AccessConfig directives here.=0A=
#=0A=
# The configuration directives are grouped into three basic sections:=0A=
#  1. Directives that control the operation of the Apache server process =
as a=0A=
#     whole (the 'global environment').=0A=
#  2. Directives that define the parameters of the 'main' or 'default' =
server,=0A=
#     which responds to requests that aren't handled by a virtual host.=0A=
#     These directives also provide default values for the settings=0A=
#     of all virtual hosts.=0A=
#  3. Settings for virtual hosts, which allow Web requests to be sent to=0A=
#     different IP addresses or hostnames and have them handled by the=0A=
#     same Apache server process.=0A=
#=0A=
# Configuration and logfile names: If the filenames you specify for many=0A=
# of the server's control files begin with "/" (or "drive:/" for Win32), =
the=0A=
# server will use that explicit path.  If the filenames do *not* begin=0A=

#=0A=

### Section 1: Global Environment=0A=

The only difference between your setup and the setup used to compile Zap
is that Zap was compiled on a RedHat 5.2 machine, with the stock 2.0.36
kernel.  Your using 2.0.35, does that imply RedHat 5.1?  If so there
might be an incompatability with Zap on 5.1.  Has anyone on the list
gotten Zap working on this platform?  Also, please send us the details
of the error you get with Zap.  When you say it's broken, how does it
break?  Does the starzap script fail to run?  Does it say 'Apache did
NOT start sucessfuly' and then spit up the last 10 lines of your error
log?  If so, what are those lines?

Subject: [Zope] DTML Newbie questions
Message-ID: <02bd01be63fe$f46475a0$3b7b47c1@thinkpad>

Can somebody please help me out. I've read through most of the postings to
the list, but I'm still in the dark.
I have defined a DTML documentproperty of type lines. Each line represents
the ID of another DTML document. When using: <!--#in notes-->   <!--#var
sequence-item-->  <BR> <!--#/in--> I get the ID's. I tried all kinds of
variations on this code (including the ones suggested by Amos) but are still
unable to turn those ID's into rendered objects.

Regards Wiebe Kunst

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC3E@peter.sths.org>

You need to install python... Or adjust the Makefile.pre.in to look at
Zope's internal python, instead of trying to find the external one.

Actually, from a quick runthrough of the Makefile.pre.in, you should set
the enviroment variable PYTHON to point to the local python binary; I
mean the one internal to zope, like 

PYTHON=/home/zope/bin/python
export PYTHON

(in bash)

or setenv PYTHON /home/zope/bin/python

(in tcsh) ... (and no I am not quite certain on the syntax here).

The 'make -f Makefile.pre.in boot' appears to call $(PYTHON) with
parameters that cause it to return the proper location for the python
configuration files, etc.

Good luck.

Subject: [Zope] NotMail 0.0.5 alpha release
Message-ID: <613145F79272D211914B0020AFF6401907BAB1@GANDALF>

Greetings Zopesters,

I have been working on a little pet Zope Product project for months now.
Getting hired at digicool put the brakes on it a little but I have
finally gotten the time to polish it up a bit for alpha release.

Check out:
http://starship.python.net:9673/crew/furtrapper/NotMail

for NotMail.  NotMail is a clone of 'other' popular web-mail interfaces.
Please download and evaluate.  But first a word of warning:

NotMail is alpha.  It is being released with the intention of harvesting
other developers who are interesting in breaking it, fixing it, and
improving it.  Although it is a cool program, it is unstable (try
pointing it at Exchange!) and not complete.  I have tried to document it
in code as much as possible, and it does contain a nice README.txt.  You
are expected to be able to infer the workings of NotMail by the source,
or by telepathy, whatever.  If NotMail makes your hard drive partition
go bye-bye or makes your imap server think it's a dhcp server that's the
way the cookie crumbles.

Okay, now a word of license:

NotMail is released under the GNU General Public License.  Give yourself
a piece of mind and send the Free Software Foundation a donation.  You'd
do it for NPR wouldn't you?

Now a kind word about Digital Creations:

Digicool has been kind enough to let me waste a small fraction of my
time to release this today.  They also let me use their computer to
check my personal mail, etc.  Please don't infer that because I work for
Digicool that NotMail is a product of Digital Creations.  Please do not
submit NotMail bugs to the Collector or send reports to
support@digicool.com.  These things are for Zope and other Digicool
products.  It is ok to discuss it in the list but I'd prefer all
discussion happen using the cool Confera discussion that can be found in
the same place you can get NotMail.

Regards,

Michel

What I did:

1) Extract the Zap distro into my top level Zope dir. Entered the Zap dir and
did ./startzap. 

This happened:

'./startzap /usr/local/Zope/Zap/bin/zap: No such file or directory'

2) I figured the httpd equivalent 'zap' was broken and replaced it with my
httpd (from apache 1.3.4). Again I fired up zap with ./startzap.

This happened:

No complaints this time. Apache (or rather zap) fires up correctly, but when
I try to reach the server with netscape or lynx (http://localhost/, (I
changed port back to 80)) I get 'Document contains no data'.

Same goes for trying: http://localhost/cgi-bin/Zope/manage - I get 'zero
sized reply', 'The requested URL could not be retrived'.

Now - seems like there are some settings missing from the zap.conf file?

Or if nothings wrong - then maby give the readme-file a facelift and
make it more clear to ppl like me what to do to get it running.

Zope seems just too good to just let go!!

Hope to get it running soon

I just did a fresh install and this works for me.  Can you run bin/zap
by hand from the shell prompt?

Have you tried downloading a fresh copy of the Zap tarball?

Your own httpd binary might not be compiled properly for Zope use, check
out the Zap FAQ at http://www.zope.org/Community/Projects/Zap.  Doh, I
just noticed that this is not an obvious link from the d/l page.  I will
make it so.

The conf file that comes with zap is ok.  We and others tested it quite

Subject: [Zope] Is a JPython implemention within the realm of possibility?
Message-ID: <93C0BE6A6D6AD211BC7400A0C9D8FE87731223@exton1.bentley.com>

I am wondering if it is within the realm of possibility that the Zope
project might eventually support operation as a Java program (under JPython)
in addition to operation under traditional Python.  I know it would probably
be a large undertaking and that there may well be better places to spend
precious energy, but I thought I'd register my interest in the prospect.

In our case it is a given that a specialized JVM will be embedded in all of
our products and more and more of our own source will be written in Java, so
code which can integrate with Java easily is all the more interesting to us.
We already have a product which uses traditional Python behind a web server
to provide an entirely through-the-web user interface for product
configuration/administration. My aim has been to replace the traditional
Python with JPython since we'll have lot's of Java stuff we'll want to be
using on the server going forward anyway.  It looks like Zope would enable
us to do what we are already doing more easily (and therefore better). So
here's hoping we'll one day see Z-over-P-over-J.

Yeah.  I know it would have to be slower.

Zope looks cool.

I am not the expert about this, but: Zope is written entirely in Python,
except for a few 'kernel' like components written in C.  If you
translate these components into Java, you might just have something
there.  I'm not a Java guy so I have no real idea.

> Yeah.  I know it would have to be slower.

From what Ken was telling me JPython is actually quite well designed and
speedy, even for a Java program. :)  If you've commited yourself to Java
then I assume you've allready resigned yourself to the performance
penalty and are considering it in your engineering goals.  Performance
may not be your primary goal in the first place.

This was one of the things that I hoped to see by going Open Source.  So
far there have been ports to operating systems that we just wouldn't
have supported, which is a great to see.  I'm intrigued by someone that
really knows Java picking up a JZope effort.

As for Digital Creations, I doubt you'll see us focus on it unless one
of our consulting customers requires it.  Same old story -- never
enought time :^(

Subject: [Zope] Connecting Zope to Sybase: Linux or Irix ?
Message-ID: <199903011940.LAA18485@sam.engr.sgi.com>

I'm just beginning with Zope, and just beginning with a
project to develop some new software product management
(bug tracking and such) tools for use within Silicon
Graphics (SGI).

Zope appears to be an excellent fit for many of our
needs.

I will need to connect with an existing large Sybase
database (the existing bug data).

I can freely choose to use either Linux or Irix for
the server side operating system.

From which server O.S. would it be easiest to get Zope
connected to Sybase?  Something I read on www.zope.org
led me to suspect that I should use Irix, so that I
can use our Sybase licensed library, and that Linux
wouldn't work, because of a lack of the needed library.

Is that so?  Any other obvious factors that I should
consider in this choice?

Hmmm - I'm a slackware guy. And no glibc guy either....

Still the zap bin starts from the prompt and when I changed some settings in
zapctl then ./startzap also worked. That is the zap process shows on ps, but
I'm not able to connect to the server with any browsers.

Now - whats wrong?

My guess is that the hardest part of such an undertaking would be to
convert Jim's extensions to Java/JPython.  Specifically, ExtensionClasses
and Acquisition are probably the hardest to do (I believe many of the
others are just fast implementations of Python versions).  Jim Hugunin
mentioned that he had thought a bit about ExtensionClasses, but I'm not
sure how far that went. The efficient POS and other extensions are also
clearly a significant undertaking, but maybe not as hard to translate.

However, I don't see it happening until someone has a commercial
motivation to invest the large required number of hours into it.

Zope relies on a lot of code in C as well as Python, so I doubt you'll see
Zope on JPython anytime soon.

However, ZPublisher (Zope's ORB) could be made to work with JPython without
too much trouble. In fact a while ago I tried this and succeeded, though it
was quite slow. The main issue is that ZPublisher uses 'regex' while
JPython uses 're'.

FWIW, my shop is running Sybase OpenClient 11.1.1 on IRIX 6.2, 6.4, and 6.5
on a Challenge/S, O2000, and Challenge/L, respectively.  I successfully
installed ZSybaseDA into Zope on the Challenge/S; haven't tried on any others.

Also FWIW, I have experienced nothing but problems getting PCGI to work on
any of the IRIX platforms; your mileage may vary.

(Coincidentally, the company I work for owns a couple hundred SGI boxes and
we keep our inventory of them in a ZPublisher app...  it's on mySQL,
though, not Sybase.  OTOH, our request tracking system is a
ZPublisher-on-Sybase app.)

Does this include the latest version of PCGI?  

FWIW, I'm willing to work with anyone getting PCGI

Both sendmail and DNS are properly installed since I was able to send

I'm no Zope expert, so any suggestions appreciated.

The last version I tried was the one distributed with Zope 1.9.0 - it
exhibited the same fail-on-process startup behavior as previous versions,
so I went to ZServer as a stopgap until I could complete a FastCGI
replacement.  I'm now using FastCGI, so it's no longer an issue.

Actually, some time ago I sent Jim some code that was a regex mockup
implemented using re.  It didn't do all of regex, but enough to make
DocumentTemplate work.

At first blush, I'd say that the host you've defined as the target of 
mailhost does not accept or is not running a mailer on port 25.

Are you certain you have mailhost setup correctly?

I Followed the URL backward from:
Michel Pelletier's "You've Not Mail !!!"  Page,  
http://starship.python.net:9673/crew/furtrapper/NotMail

Hey, this is neat,  starship.python.net must be 
running ZOPE because the port is "9673" !!!  
therefore going to:
http://starship.python.net:9673
"Welcome to Zope at the Starship Python!"

So, to join the crew of the Starship and get your own
ZOPE pages on the internet requires PSA membership.
One can join now and pay for a half year $50/yr 
or $25 for half.  Membership wouldn't be effective
until April 1st (a Foolish day!) 

So, Zope is cool and so is Python.  I am considering
joining PSA on the strength of Zope and Elegance
of Python but I'm concerned that Python doesn't seem 
to have much "MindShare" like Java or Perl.

Ok so our local Borders has only one book on Python:
"Programming Python" by Mark Lutz (Pub: O'Reilly)
A great book that is dated 1996.  The shelves are
full of books on Java and there are quite a few Perl books.

What is the BIG PICTURE here?  Is Python so good
that lot of programming tomes are unnecessary?

Why is there so little press on Python and so much
for the less Elegant and slower Java?

Is Python a "secret weapon"?  If so, the secret should
get out to the world so Python gets more mind share
and doesn't develop cobwebs.

***So, where are the rabid Python fans?***
Yes, a bunch of them are on the ZOPE list.

Great answers to these questions will only help ZOPE!

I'm using pcgi from 1.9.0 (README says it's 2.0a4) under Irix 5.3 (yes, I
know, I keep bugging the sysadmin to upgrade :) ).  Occaisionally, pcgi fails
to start up, logging "Interrupted system call  (116) unable to connect, fd=4".
I also had the same problem when using FastCGI w/ threads: the application
would hang and I'd get an "interrupted system call" in the log after a while.
I have never experienced either of these problems under linux, so might this
be an Irix problem?  I remember that Philip also suspected an Irix
"sockets-and-threads-don't-mix" problem, which appears to be what I have
experienced as well.  Philip, is theaded FastCGI still broken on Irix?

As a language qua language, Python is so good in design
and implementation that it has few dark mysteries that
require a lot of documentation to explain.

The existing Python books are quite good, with at
least 4 more in the works.  More Python books are 
necessary to explain things like Win32/COM programming, 
for instance, than the language itself.  Perl has
lots of books, because for the past 2 years, almost
anything that offered to make Perl programming easy
was given shelf space.  Java has lots of books
because almost everything in Java has to be written
in Java, and the Java libraries have been a moving
target for so long.

More important than the number of books (how many
Perl books do you really need, after the Camel?) is
the level of support/platforms in the Python community,
which is quite high.  It will probably never attain 
the proportion of mindshare that Perl or Java has,
but is has critical mass, and a lot of compentent people
who contribute code.  Too many companies now rely upon 
Python as their core development language for it to go 
away anytime soon.

More importantly:  You'll spend more time learning about
the eccentricities of whatever your environment demands,
be it Unix, Windows, web servers, CE devices, COM, Tk, etc.
than learning the language itself.  This is Python's 
great (and under-reported) strength.

Message-ID: <36DB1478.E2D7915E@avalongroup.net>

Hi all,

This is probably more of a newbie Linux question than a newbie Zope
question, but I'm going to ask it here anyway:

I would like to connect Zope to a database, so I have setup both
PostgreSQL and MySQL. My reading tells me that MySQL is probably the
better choice as a web backend (Any comments from those of you more
knowledgable than I would be appreciated!) So I downloaded the MySQL
source, compiled, installed and tested it. It looks like I did it right.
I then downloaded the ZMySQLDA from the Zope site.

I have followed the directions--I think, but get the following error
when trying to do the initial make:

[tjg@puddleglum src]$ make -f Makefile.pre.in boot
rm -f *.o *~

FYI:  I know of at least 5 other Python-related book projects in various
stages of development.  One of those should be hitting those same shelves
in April sometime (http://www.oreilly.com/catalog/lpython/).  It even
mentions Zope in a couple of places.  [Disclosure: I'm a coauthor of said

Python is certainly easier to learn than some other languages.

Mostly, because Java is backed by a multibillion dollar company with lots
of $$'s for public relations.

A perfectly reasonable suggestion - and one that I have made many times myself!
<g>

I did, in fact, RTFM - but the FM makes absolutely zero mention of anything
"leverish", to adopt a seemingly Zopish mode of Englishish. ;-)  I followed your
link given in another message, and realised that what I had been reading about in
terms of Product Distributions was (I think) what you refer to as the "Lever".

IAC, I followed the instructions given, and when it didn't work I went back, and
worked my way through the Product Tutorial exercise - excellent!   The POLL
product works fine!  But the levered faq product .DAT file apparently failed to
unpickle - as described by others in this thread.  My product management screen
shows the FAQ product as installed, but the actual product directory still has
just the three files from the tarball.  In my case, however, it is on a Linux ZAP
system - so the problem is not confined to Win32 as others have conjectured.

Hope this helps, and apologies for the lack of specifics in my previous post.
Can we please have the term "lever" clarified and documented a little better.

My experience was MySQL had better support for large
streams of text data and blobs than PostgreSQL.  However,
MySQL also lacks support for transactions.  This probably
contributes to its speed, which in turn makes it popular
for web apps.

THis is completely correct.  The access file is ONLY for the

I assumed that the .DAT file contained all the component DTML and PY scripts etc
and that these would be expanded into the Product's home directory somehow.  Is
this not the case?  Is the .DAT distribution a way of  distributing the objects
without the source ? (more Cathedral than Bazaar)

Note that you could, pretty easily, write a new UserFolder type object
which worked off an access file. Could be useful for people who are generating
the access file from an /etc/passwd file, or whatever.

You could also skip the generation step and write a UserFolder which
works off of /etc/passwd.  In fact, NotMail could use this as a helper
too.

Subject: [Zope] ZServer and MSIE (long & detailed)
Message-ID: <l03130300b30112942a29@[206.40.158.77]>

Has anyone else experienced a problem getting Explorer to connect with
Zserver?  I have no problem with any version of Navigator but MSIE 3.01 and
4.0 and 4.5 for both Mac and Windows throw up an error box claiming an
"error with Explorer's internet extensions has failed".

Very baffling, I can connect just fine via telnet using the following
requests, ZServer (medusa) returns a proper html page.

Requests sent:

GET / HTTP/1.0
Connection: Keep-Alive
Host: www.fishwrapper.com
Accept: image/gif, image/jpeg, */*

GET / HTTP/1.0

GET / HTTP/1.1

response recieved:

blah, blah, blah.....

(note the difference in the sent host and recieved host, the host arg in
the start script sets the host for the ftp server, not the webserver...)

I can see nothing in the responses that would cause MSIE to fail, note this
has been tested from four different PC's on three different ip's, including
a local connection from my Lan.

Strangly enough I did a stream capture and hit my server and the startship
server (also running ZServer) and the two responses differ even though the
requests were from the same browser on the same connection.

Do starships ZServer and mine differ?

My  http_server.py  script carries RC_ID of:
 "v 1.4 1999/01/18 22:44:49 amos"  I downloaded a fresh copy of ZServer
when I grabbed the newest copy of Zope.

Any clues? I've been documenting and testing everything I could think of,
I'd report a bug but it seems MSIE works with the Starship server, so I
think it's not a bug so much as something wrong on my end?

Slackware V 3.6
Zope v 1.10.2
ZServer 1.0a2

I understand the security problems inherent in ExternalMethods; unfortunately,
without them, Zope is merely an "also-ran" in the web applicaton race, from my
perspective.  DTML in isolation is not an "ASP-killer."

I'm CC'ing the Zope list, in hopes that someone there can either allay or slay
our fears.

It seems to me that the security problem is that ExternalMethods can get access
to "sibling objects" of the object on which they are invoked, right?  I mean, if
we could make the siblings inaccessible, and acquired properties read-only, then
we should be ok, no?  Ugh, I don't grok acquisition well enough to tackle that
myself, I fear.

Subject: [Zope] terminating DTML parsing...
Message-ID: <199903020647.RAA07473@mbuna.arbhome.com.au>

from inside DTML, is there a way to say "don't process any further DTML,
just return this to the user"?

What I'm looking at is a small DTML snippet that gets included at the
top of a number of pages, and looks for a particular variable to be
set. If it's not set, it should just display a small "please enter a
widget name" form which submits back to the same page, and not display 
the rest of the page at all.

will just doing a RESPONSE.redirect() automatically do this?

Message-ID: <129.78.8.1.126.8280.920360936.257.8891>

I'm making a Zope "Product" for managing and creating student surveys
(which I hope to contribute via zope.org) but I'm having trouble with a
couple of techniques:

1.	How does one enable a dtml file that is instantiated as in
		my_dtml = HTMLFile('my', globals())
	available for editing in the products' management screen?

	There's probably more to this - as at the moment the management
	screen goes straight to the "index_html" form as with the "Poll"
	Product.

2.	What's the approved way to catch database errors in methods?

	I'm creating tables on the fly, and need to check if the table
	exists before trying to create it. (I'd use a "tables" method if
	all the database interfaces supported it. I'd also use a try/except
	but the database objects have different names for their exceptions.)

Message-ID: <8174B1EE3D2CD21180960000F8056723CFB321@telisnt1020.is.tel.co.jp>

Hi All!

First off, I'd like to thank Digital Creations for an excellent (and
really fun) product. 

I'm building a prototype web site interface for a database where I
work using Zope 1.10.2 and the ZOracleDA product and have a some
questions. 

1. When trying to do a join (a lazy query, I know) like:

   select a.*, b.*
   from tablea a, tableb b
   where a.b_id=a.id

   Both tables have an ID column so Zope raises a 'ValueError'
   exception with the  message 'Duplicate column name, ID'.
   I wonder if instead of raising an exception something like the 
   following could be done?

   A diff of Shared/DC/ZRDB/Results.py:

120,131c120
<                 #raise ValueError, 'Duplicate column name, %s' % name
<
<                 #instead of error, append an extension to
<                 #create a unique name
<                 tempname=name
<                 nameext=1
<                 while schema.has_key(name):
<                     name=tempname+'_'+str(nameext)
<                     nameext=nameext+1
<
<                 #update with newly created name
<                 item['name']=name
---
>                 raise ValueError, 'Duplicate column name, %s' % name


   I tested this some and it seems to work. Are there any problems
   that could be caused by doing this?

2. I'll post the other questions separately because they are
unrelated. 


   TIA!,

The .DAT file only contains information to be added to the Object Database. It
won't be expanded into files onto your harddisk.

Zope stores all instances of classes in it's object databse, via a process
called 'pickling'. This, in simple terms, means that all data stored in an
object is turned into one stream of data that can be stored in a file.

As a 'Levered' product contains nothing but instances of classes, not the
classes themselves, it suffices to distribute only the compressed pickled
contents of the product. The source for the used classes you allready have (at
least with the FAQ you do, it uses only DTML Methods and Folders), and the DTML
scripts can be viewed in Zope, so you do get all the source.

The objects that make up the product should normally be automaticly
decompressed and imported into Zope, but the decrompressing seems to be
failing.

val wasn't set to None and so the null attribute never got used. Since
None is false, the above should be OK. (It seems to work for me,
anyway :^)

That works fine if it's all one big DTML method. But what if you have
a series of pages which each have
<!--#var check_widget_settings--> at the top.
inside check_widget_settings I want to be able to say "if this, then
enough. don't return back to the enclosing objects, just send what
you have now." kinda like a DTML exception :)

Subject: [Zope] AUTHENTICATED_USER
Message-ID: <153C1D93564@sahara.cspt.es>

Does anyone have any more information on AUTHENTICATED_USER? We saw a while 
back that it has properties (AUTHENTICATED_USER.has_role(['Manager', 
'Editor'])). I would like to be able to get the user name, and use that to 
index simple files for users. Is there something like 
AUTHENTICATED_USER['UserName']?? This is essentially the information that is 
returned if you try <!--#var AUTHENTICATED_USER-->. However, if you try 
something like <!--#if "AUTHENTICATED_USER in objectIds()"-->, it does not 
work.

The only way I have been able to use this information so far is to put 
<INPUT TYPE=hidden name=userID value="<!--#var AUTHENTICATED_USER-->">
in a form, and pass it in a REQUEST to another page. But I want to be able to 
get this information directly. I have even tried REQUEST.set('myUser', 
AUTHENTICATED_USER) inthe header, but this has the same problem 
(unsurprisingly) as AUTHENTICATED_USER itself.

Any hints?

Thanks,

JP

Message-ID: <XFMail.990302130621.julian@zereau.net>

I want to call a function I have made, with arguments.

1) is there any way to call it direct, complete with module name? It would mean
getting Zope to import that module.

2) I know I can put it in an external metod and use <!--var mymethod--> but it
needs arguments, so I'll need to set and re-set the same DTML-namespace
variable throughout the document, in which case, how do I alter/set DTML
varibles from within DTML?

AUTHENTICATED_USER itself is an object -- the reason
<!--#var AUTHENTICATED_USER--> gives you the user name
is that it effectively does an str() on the user object.

To work with the user name directly, you can use the
getUserName() method of the user object:

<!--#if "AUTHENTICATED_USER.getUserName() in objectIds()"-->

I am not sure I understand your problem. Default arguments can be given in
the definition of the function. If you need to pass a variable in an
external method you can just do
<!--# var "mymethod(myvariable)" -->
Additionally the self argument in the external method definition is
replaced by the object (or containing folder) that calls the method so you
have access to the namespace of the object through self.

Where is your function located? Is it an external method? In this
case imports in the method's file work fine, but only inside Zope's
search path (practically, the installation path and lib subdirectory).
A good place to put your modules and packages is the 
lib//shared/<your company> dir.

That works fine if it's all one big DTML method. But what if you have
a series of pages which each have
<!--#var check_widget_settings--> at the top.
inside check_widget_settings I want to be able to say "if this, then
enough. don't return back to the enclosing objects, just send what
you have now." kinda like a DTML exception :)

Use <!--#var expr="AUTHENTICATED_USER.getUserName()"-->

More hints linke this can be found in the User.py file in your
lib/python/AccessControl directory.

The following functions could be usefull:

getUserName(self): Return the username of a user
getRoles(self): Return the list of roles assigned to a user. 
getDomains(self): Return the list of domain restrictions for a user
allowed(self, parent, roles=None): Check wether the user has access to parent
hasRole(self, parent, roles=None): Check wether the user has the specified
roles
has_role(self, roles): Check wether the user has the specified roles

allowed & hasRole are one and the same. When called with parent=None, it
just returns wether the user has the named roles. has_role also checks for
roles, but doesn't automatically include the Anonymous role. So,
hasRole(None, 'Anonymous') always returns true, but has_role('Anonymous')
returns false for every user that has been authenticated.

Note that AUTHENTICATED_USER is always defined, also for anonymous access.

Here is a little example of what you could do with these functions:

<!--#comment-->Display user info<!--#/comment-->
You are the user named <!--#var expr="AUTHENTICATED_USER.getUserName()"-->.<P>

<!--#if "AUTHENTICATED_USER.getRoles()"-->
  You have the following roles:

  <!--#in "AUTHENTICATED_USER.getRoles()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You have no roles defined.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.getDomains()"-->
  You are allowed to log in from the following domains:

  <!--#in "AUTHENTICATED_USER.getDomains()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You can log in from any domain.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.has_role(['Manager'])"-->
You have the 'Manager' role.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['Anonymous'])"-->
You have the 'Anonymous' role. You are therefore an anonymous user.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['nonexistent'])"-->
You have the 'nonexistent' role.<BR>
<!--#/if-->
<!--#var standard_html_footer-->

The last call to has_role is to show that the user defined in the 'access'
file in the root folder of your Zope installation, has ALL roles, including
non-existent ones. And even more interesting, the call to getRoles() will
get you 'manage', a misspelled version of the 'Manager' role. This is
probably the only way to reliably recognize the superuser.

Well, it's actually deeper than that. You are correct in saying
that DTML alone is not an ASP-killer. Consider the similarities
between Zope and, for example, ASP/COM (though the same holds true
for practically any other system as well):

ASP lets you use the services provided by (COM) objects, which may 
be provided by the server or provided independently. I'm sure that
MS tries to make the server-provided objects fairly safe, but there
is _nothing_ stopping a programmer from writing and installing a COM
object with an evil() method that wipes out your C: drive, except the
fact that presumably the sysadmin exercises some control over making
these independent services available.

The same holds true for Zope (and any other app server out there). 
Like ASP/COM, External Methods give you the ability to provide more 
powerful services for use by your application. It also gives you 
exactly the same problems (though I'm sure that evil() method could 
be developed in a quarter of the time in Python :)

Basically, with power comes responsibility, and I can't really imagine
any system that could _safely_ allow possibly-untrusted people to write
(basically) arbitrary code. It's not even really a matter of what
services
are or are not available to those people. I'm sure that many, many hours

and much brain-power went into the design of Java's security mechanisms.
Even so, if I were a web site manager I still couldn't let untrusted
users write their own arbitrary java code to run in my web or app
server.
Even after I had figured out a way to wall off every service I could
think
of that could possibly be harmful, the user could still probably just do
the Java equivalent of:

  while 1:
    pass

Zope DTML goes to a good deal of trouble to minimize these problems 
in DTML itself, and we would certainly consider any concrete ideas
on how to make External Methods safer. Can you give me some examples
of other app servers that you feel deal with safety of external 
services in a better way? I'd be happy to do some looking into how
others are dealing with this.

Make your Product a Folderoid (zopespeak for a Folder Object) that
contains it's own user interface which the manager can edit.  Your
__init__ function initially loads the documents off disk into the
Folder.  Confera and NotMail both do this (Confera does it a little

There absolutely does need to be an "unprotected mode" available though - the
system designers might *need* it to do scary destructive things like deleting
files. Zope should not get in the way.

This is an excellent post.  I want to add that _getPassword() is a handy
function also if you want to use your Zope user to authenticate into an
external system, like POP3 or IMAP.

The "print" goes directly to the webserver, which confused it: it
expects
HTTP headers like "HTTP/1.0 200 Okay".

The "return" sends your data to *Zope*, which then does the header stuff

for you.  Same with cookies, content-type, etc.

Summary: dont use 'print', or redirect stdout to a log file.


Now the problem is deeper, what shall I do when I am import C++ Modules
in Python ( extending Python),
and that modules are writing to the stdout via "cout" or "printf", I
have no influence to that.


If I change the stdout via "freopen( "file, "wr", stdout )" or stuff
like that, I have no chance to switch back
to the *real* stdout  ( look at the c-faq of comp.lang.c ), and I *have
to* switch back because of the cgi-mechnism,
which uses ZPublisher.
The only the chance to handle stuff like that is to work with two
processes in the Zopemechanism.
A Zopeserver which tells the Zope Client to start a pythonfunction. Now
all stdout happens on the
client and the server listen for a string on a socket ( or something
similar ). Now when
the server gets the string it does all necessary wrapping ( content-type
and so on ), and
send it to the Xserver via its stdout.

Or is there a less complicate solution ?



 Thanks in advance

   Armin

That's unfortunate, but we understand.  Getting *anything* to work with
Apache's mod_rewrite module is quite a chore.  It doesn't help that
distributions like RedHat 5.2 ship it in a broken way, then people blame
us for it, then we track down a problem that is completely outside Zope.

Did you follow the recommendations to start with the built-in webserver
before trying integrate with Apache?  If so, did that work?

I believe this is allready under construction:
http://www.zope.org/Community/Services

By far from incomplete, but it is the right direction. I think Amos' FAQ tool
should be utilized there somewhere, and maybe some people from this list
willing to help out DC should fill it in, because it looks like Ken Manheimer
(who has been charged with community communications) allready seems overloaded.

What about

select *
    from tablea a, tableb b
    where a.b_id=a.id


Wouldn't this give you vars called a.id and b.id?

Hmmm... I bet Zope won't like that.

It occurs to me that a DTML document could contain this in a transparent
sendmail form, assuming there is already a handy Mailhost set up, to capture
and mail off the password of anyone browsing the page...

Not really -- you can't access _getPassword() from DTML. You would
have to write an external method to do that (which implies that
you have access to the filesystem, and could get the passwords
anyway if you wanted them that bad...)

While we are on the subject of AUTHENTICATED_USER, I would like my users to
be able to "logout" so that they then become anonymous again.

Any ideas?

I have seen this on Dejanews. It would be useful so that authorized users
don't leave themselves logged in if they don't quit Netscape.

	Is there any chance that you're trying to do something
	like:

	select *
	from a, b
	where a.b_id = b.id
                       ^

More generally speaking, we should be organizing the Zope documentation
project. There was word of it before, but haven't heard much on it
recently. In fact, the messages that I can find in my mailbox on it is
people saying we should start such a project :). I'd obviously be very
useful.

As an example: I myself have sent some (obscure) questions to the list
the week before last, and have only managed to receive an answer that
confused me more (I welcomed the answer though, of course!). I sent more
questions and observations last week, but haven't received answers yet
(perhaps it's because I'm doing something fundamentally wrong with Zope
but I'd like to hear it if that's so). Of course I'd like to see my
questions answered.

A FAQ would help filter out all the less obscure questions so that my
obscure questions might get answers. :)

So, the Zope Communication Project (hereby started if it doesn't exist
yet, this is open source after all :) should make its first priority to
create a fairly exhaustive FAQ. I currently have some time to invest in
the ZDP (he said, tempting fate; work's slow right now, but this can
change quickly).

Anyway, I'll help. If only with the *questions* side of the FAQ,
perhaps, but I can help. :)

Initial Plan of Action for the ZDP:

- Produce a fairly exhaustive FAQ, mining the mailing list for good
questions and answers.

- Organize the ZDP itself. :)

Regards,

Martijn

Subject: [Zope] [ZDP] Announcing the Zope Documentation Project
Message-ID: <36DC17B8.7F5CFF6A@pop.vet.uu.nl>

Hi there,

Hereby I announce in absolute adhoc anarchistic fashion the Zope
Documentation Project. The Zope Documentation Project aims to generate
documention on anything Zope.

The Zope Documentation Project needs people who wants to help. It needs
these people to get organized.

To get focused, I propose the ZDP's initial project is to provide FAQs
on various Zope topics. We can mine the mailing list for good questions
and answers.

The ZDP asks everybody to contribute. Right now we need everything. :)
We need questions and answers, and we need to categorize these in
separate FAQ sections. We need Zope webspace somewhere to put up the
FAQ, I assume using the FAQ product. We need to develop the FAQ product
further, if necessary. We need whatever you can think of.

The prime mean of communications for the ZDP is the Zope mailing list,
until further notice. I suggest that to keep the mailing list somewhat
organized we prepend our mailing list subjects with '[ZDP]'. If somebody
has a better way, we'll do it a better way.

Note that while I'm sending out this message, I'm not anything official.
I'm just attempting to get the ball rolling.

*nudges the ball*

Regards,

Martijn

Could it be a 1.5.1 vs 1.5.2b2 thing?  I have 1.5.1 and it failed for me.
Is the zlib.pyd in 1.5.2 based on a newer version of the zlib library that
may not be forward compatible?

I don't have any experience with Zope or even Python, but am I right
in guessing that this looks like a problem with the python binary and
not with Zope?  Any ideas to precisely what the problem might be?

python is v1.5.1.
C compiler used is gcc 2.7.2.x.

I finally got it working - just couldn't get it off my mind. Was kinda
mindblowing the whole thing but finally - YES I MADE IT! :)

What I did was to jump off the mod_rewrite thing and try let apache handle
the authentication all together. At first I didn't know of the htpasswd
binary (stupid as I am) so things didn't work at first. Then htpasswd lit my
eyes - did the 'htpasswd -c' thing and ended up with a working AuthUserFile.
Now the trick was to configure the damned thing in httpd.conf - this worked
out ok:

"""
ScriptAlias /cgi-bin/ "/usr/local/apache/cgi-bin/"

<Directory "/usr/local/apache/cgi-bin">
	AllowOverride None
	Options FollowSymLinks ExecCGI
	Order allow, deny
	Allow from all
</Directory>

AddHandler cgi-script .cgi

<Location /cgi-bin/Zope/>
	AuthType Basic
	AuthName Zope-in
	AuthUserFile /usr/local/apache/conf/zope_auth
	require valid-user
</Location>

# 'zope_auth' created with htpasswd -c /usr/local/apache/conf/zope_auth \
'username'

"""

Actually - just like the manual tells me to. I did some wrong links and
generally fucked things up. Thanks for keeping me going at least (that goes
to all U ppl answering me) - sorry for taking up your time.

Message-ID: <613145F79272D211914B0020AFF64019069109@GANDALF>

Hello everyone:

Some of you may know that many moons ago we (Brian) developed a plug-in
for Netscape Enterprise Server (ES) 2.x (and FastTrack -- based on the
same libraries) that addressed Netscape's nasty habit of removing
authenticated_user information from the environment before calling CGI
apps.  Obviously, this has a deleterious effect on interesting zope
applications.

Fortunately (?), we are up to our armpits in projects and initiatives.
As a result, we need someone to do a bit of work to upgrade the plug-in
from ES 2.x to ES 3.5.x.  I can provide the following files from our 2.x
incarnation:

o  plug-in source code
o  obj.conf
o  magnus.conf

The source code is only 153 lines of generously formatted C (w/lots of
defs) so I'm hopeful that this isn't a HUGE task.  I'm interested in
hearing quotes from people in the community that have experience with
the NSAPI and would, for a reasonable fee, develop, compile (Solaris 2.6
and NT4) and test an upgraded plug-in.  The work would be contributed
back under the ZPL.

Naturally, I'd also entertain offers from people to do this for free!
:^)

--Rob

P.S. - I KNOW there are some NSAPI wizards out there so don't be shy!

How about Mr. Creosote. This is a wonderful little utility from Jeff
Bauer. It basically an example implementation of socket datagrams... ie.
it lets you print out via a socket to a little server program. Its great
for debugging Zope/Bobo apps.

Here's Mr. Creosote's web page for more info...

Please don't ge me wrong:  I _like_ ExternalMethod / Product as a way to extend
Zope.  My comment is in the context of not (currently) being able to add
ExternalMethods to my Zope demesne on starship, given the (quite legitimate)
security concerns of the Zopemeister.

I looked at the ExternalMethod source last night a bit:  the actual method
execution is done via an apply() call, after loading and compiling the code for
the function.  We might be able to come up with an alternate product which used
a carefully tuned rexec() (Bastion?  I plead ignorance), operating on Python
code stored in the Zbase itself.

The particulars of my case are that the control structures of DTML are not quite
powerful enough to accomplish my task;  of course, strengthening them, even in a
"sandbox" model, still leaves open the possibility for buggy/malicious code to
do ugly things (like your example below).

Any Turing machine can do "while 1: pass", so no sufficiently general syntax is
"safe" from this attack.

Actually, the possibility which seemed most interesting was Doug Wyatt's
suggestion of "federating" a set of independent Zbases under one (at least
apparently one) server.  Then any damage my ExternalMethod did would be to the
Zbase would be on my own head, at least.  If that server were actually a process
running as me, then standard system security procedures should probably be fine.

You might want to consider switching to one of the official binary kits
available from MySQL's homepage. MySQL is notoriously picky about how it
is compiled.

Looks like you didn't install the development libraries for python
(python-devel or python-dev).

This was an idea I'd proffered, but honestly haven't looked at enough
yet to know whether it would work... it SHOULD work, but it might
require some modifications to the aquisition code, but I've not looked
neough yet.

Well, it might help if you offered what control strucuture you need, we
might be able to come up wit han interim solution.

TO me this is just a hack to get around it near term, and doesn't fix
the problem.  Also if you have 100 users, do you have 100 instances of
zope running under 1 ZServer?  That sounds like a true administrative
nightmare...  And substantial overkill.

Ok, the "teeth-cutting" example I am trying to implement generates math-facts
problems for my five year old.  In Python, two trivial functions:


I _think_ this one is easy in DTML:

    def problem( max_term, operators ) :
        """ Generate a single math-fact problem whose terms are within
            range( max_term + 1 ), using one of the supplied operators.
        """
        lhs = random.randrange( max_term + 1 )
        rhs = random.randrange( max_term + 1 )
        operation = operators[ random.randrange( len( operators ) ) ]
        return ( lhs, operation, rhs )

But not this one:

    def gen_problem( max_term, operators ) :
        """ Generate a math-fact problem whose terms and results are all within
            range( max_term ), using the supplied operators.
        """

        while 1 : # Arbitrary looping! (could benefit from
                  #   the dreaded assignment-in-conditional :)

            probStr = "%d %s %d" % problem( max_term, operators )
            result = eval( probStr )

            if 0 <= result and result <= max_term :
                return probStr

And of course, the DTML syntax for something like this is going to be ugly.

One instance per "sandbox", not one per user (although on starship this is a
distinction without a difference).  The "content manager only" applications will
do fine in a single Zope instance, as now.

In my experience many situations where external methods are needed do not
require access to the Zope data tree, like the math test example you
presented. 

One approach is to use a second server that does XML-RPC (Fredrik Lundh
has already written a client and a simple server) and set an
account/folder where everybody can upload their scripts and access them
through XML-RPC calls from their Zope environment. I suppose we can write
a product that provides the client site of the XML-RPC based on Fredrik's
implementation. As for the server site Jim once mentioned that the support
should go in ZPublisher but initially a simple server based on python
standard libraries will be adequate. Or use the newly released asyncore
libs though I suspect a multithreading server will be better in this
situation.

If however one requires access to the 'self' argument of an external
method such an approach will not be adequate. Usually though one can
collect the relevant parameters by using DTML calls and send them to the
XML-RPC server for processing.

Message-ID: <016401be64f3$2e5b79d0$8725d2d1@rogue.jenkon-dev.com>

I have a folder with various boolean properties associated with it which are
accessed by the dtml docs as flags for enabling or disabling content.  Turn
off the flag and a chunk of the page goes away when it is next viewed.  This
works great, but I would like to associate that behaviour with the security
attributes.  In other words, when somebody in the Anonymous role is viewing
objects in the folder the properties should be unset, but when users in the
manager (or some other specific role) view the pages then the properties
should be set and those parts of the pages are activated.

How can this be done?

Thank you, Martijn, you've made my day!  This is extremely cool.  

As you might expect, here at digicool we're yearning to produce more and
better documentation, and, as with other things, we want to have more
time and energy to do it than we do.  This kind of effort from you, and
from anyone else who can help, is *severely* appreciated.  I know i'll
be participating - question is, besides scraping together the time we
can, how else can digicool help?  Some thoughts, below...

Some thoughts:

 - We would be happy to provide a mailing list or two for you all

 - If it makes sense (logistically, for us as well as for you), we could
host 
   the FAQ stuff or whatever on zope.org.  This we'll have to discuss -
both
   what all might want, and what we can safely and effectively do...

(I've been thinking about requirements for a collaborative FAQ
mechanism, which can be tricky if you want it to be available for
contribution to the community in general, yet still remain organized
enough for people to find what they're seeking.  An interesting
problem...)

For those interested changing the "chunks=1" to "chunks=0" in

Zope's, I don't consider this a bug with ZServer but with MSIE as this also

Hm - this indicates you've upgraded your Python since the module
_pg was compiled (postgres?)
It's not the cause of the following error, but it is something you might
want to fix, anyway.

The error looks to be caused by ZopeHTTPServer not handling a client
aborting the connection. Looking into the code, at around line 240 of
ZopeHTTPServer/ZopeHTTPServer.py, the write() method of ResponseWriter
should probably trap IOError and ignore it. 
Something like wrapping the two calls to write() in the write method
like
  try:
      write....
  except IOError:
      pass

would be a blunt fix to it. I don't think DC want to continue to 
support ZopeHTTPServer, tho. You might want to try to upgrade to ZServer,
instead.

No, because from DTML you can't call methods starting with an underscore. This
was actually the reason I didn't include this in my overview.

You can still use it in en external method, I know. But then again, I can do a
heck of a lot more bad things in external methods.

This is very hard to do from the serverside. I can force a new login, but I
cannot stop a browser from authenticating itself at every request, therefore
effectivly becoming anonymous.

Problem is more that HTTP is stateless, a user is not 'still logged in', but it
autenticates itself at every request. Only when the server says that the
authentication is incorrect, does the browser ask for the username and
password.

What you could do, is write your own UserFolder/User combo, that stores a
last-access time on the User object, and checks for this every time a user is
authenticated. If the difference is greater than, say 15 minutes, you force a
reauthentication by raising a permission denied.

I tried playing with this once upon a time, but I found that the stupid
browser still cached the original result and would continue to use it after
the failed login/relogin combination. Most frustrating.

Subject: [Zope] need help with IIS/ODBC
Message-ID: <3.0.6.32.19990304173128.008fc510@hito.eccosys.com>

As a novice (who's loving Zope!) I'm having a terrible time trying to get
Zope1.10.2 on NT with IIS to connect to MS SQL with a Z ODBC connection.
Previously I had no problem getting Zope 1.9/ZopeHTTPServer to connect to
MS SQL via Z ODBC. 

Recently I upgraded to 1.10.2 without a hitch, and was able to run it with
IIS 4.0 after putting the (PCGI executable?) MYZOPE.exe in
/InetPub/scripts/ and turning off in IIS both Basic Authentication and NT
Challenge/Response as I read here in the list.

My problem now is that when I try to open my db connection (exactly the
same connection that was working with 1.9 & ZopeHTTPServer) I get the
following error from IIS:

>HTTP Error 400
>400 Bad Request
>Due to malformed syntax, the request could not be understood by 
>the server. The client should not repeat the request without modifications.

In trying to figure out what's going on I've noticed a couple things.
First, and I think most illustrative, if I try to add a new Z ODBC
connection, none of my ODBC sources are showing up in the available list
(except the default 'LocalServer, SQL Server') - whereas if I run my 1.9
Zope with ZopeHTTPServer all my ODBC connections show up just fine.

Also, running my new 1.10.2 Zope/IIS with the faulty db connection side by
side with the functioning 1.9/ZopeHTTPServer, I printed our the environment
variables of both and noticed some differences - USERPROFILE's are Default
User vs. Administrator, and the 1.9/ZopeHTTPServer contains variables not
contained in the 1.10.2/IIS environ: HOMEPATH, TEMP, USERNAME, HOMEDRIVE,
USERDOMAIN, PROMPT, LOGONSERVER, TMP. I attempted to set at least
USERDOMAIN in the 1.10.2/IIS environ, with no luck.

I've read all the posts from the list that I could find dealing with IIS
and ODBC, but couldn't find anything with info on this type of trouble.
Have I made a boneheaded mistake and started to look in the wrong places
for the fix? Any help/info/pointers would be hugely appreciated as I
continue to bang my head on my keyboard hoping that I'll soon clear this
hurdle and get back to having fun with Zope!

Thanks!

Jay

You could, using AUTHENTICATED_USER.has_role() and manage_changeProperties(). I
think it will be better if you completely skip the property setting though..

You could just show content using
<!--#if ATHENTICATED_USER.has_role(['Anonymous'])-->
        Content _only_ for the Anonymous user
<!--#/if-->
<!--#if ATHENTICATED_USER.has_role(['Manager'])-->
        Content for users with the Manager role.
<!--#/if-->

This way you don't accidently let any properties float around, causing content
to be shown to the wrong people.

You can use the #in tag's grouping features for this. If you use GROUP BY in
your SELECT statement, or use the appropriate sorting, you can use the
following DTML code to get the desired output, assuming the column names are
the same as in your example:

<!--#in MySQLMethod sort=field2-->
<!--#if first-field2-->
    <!--#var field2 fmt="DayOfWeek"-->, 
    <!--#var field2 fmt="Month"-->
    <!--#var field2 fmt="day"--><BR>
    <BLOCKQUOTE>
<!--#/if-->

<!--#var field1-->

<!--#if last-field2-->
    </BLOCKQUOTE>
<!--#/if-->

<!--#else-->
Sorry, no colors in your query.
<!--#/in-->

The variables first-xxx and last-xxx are set whenever the field with name xxx
starts/ends in a sequence. For more information on this, read the Zope DTML
User's Guide (http://www.zope.org/Documentation/Guides/DTML

Subject: [Zope] ZPublisher and creating children
Message-ID: <36DCF9B5.97A62E66@acriter.com>

Hi,

I'm using ZPublisher+DocumentTemplate+BoboPOS in a cgi environment,
because that's all I need (and can use on my ISP's box). In the couple
of things I've developed so far, a pattern has emerged that disturbs me:
if you have a container object, when adding a child, the whole add thing
is done in the parent. IIIRC, I fetched this design from the (Bobo)
Trinkets example when I started:

class Container....
     add = HTMLFile(....)
     def do_add(self, childattrone, childattrtwo, childattrthree):
        d = self._items
        d[childattrone] = Child(childattrone, childattrtwo,
childattrthree)
        self._items = d

class Child...

     def __init__(self, childattrone, childattrtwo, childattrthree):
         ....

     edit = HTMLFile(....)
     def do_edit(self, childattrone, childattrtwo, childattrthree):
           ....

The Container, IMHO, "knows" too much about the Child in this case, and
it's hard to modify the attribute set of the Child class. Am I doing
something wrong? Is there a design pattern here I'm not aware of?

Regards,

Cees

These are good ideas (and thanks Chris for the offer!), but Ken
Manheimer later on in the list is offering space on www.zope.org, and
that would of course be perfect.

It was getting obvious that this was so. You guys all did a great job,
and still are doing a great job, but the volume of questions and
documention requests has exploded in the mean time. Which is great, in
fact, of course, as it shows people are interested.

This would be great! We probably don't want to be spread out too much so
one mailing list would be best (zdp@zope.org?). I also intend to make
regular announcements of ZDP's progress (and some advertising to get
people more involved in the project) on the main Zope list (or future
multiple main Zope lists :).

Right now though to keep the ball rolling I'll be using the normal list
to send out messages.

Zope.org would I think be the ZDP's favorite place to be hosted on, so
that'd be very nice. Your thoughts on how we could best arrange this
(who gets manage access to the place, if we develop in a branch we
export to you, or develop in there directly, or use FTP, or possibly
something else, etc) are welcome.

Independently (for local purposes) I've been thinking about making a FAQ
wizard product myself, but I got stranded somewhere in the beginning (my
laments I posted some time ago to the list :). But at least I've given
some thought to the design. Now Amos made one, and we can build on that.

The use of the tree tag is nice, but probably a simple list is more
useful in some cases (one can do a text search in it, for instance).
From my cursory glance at the management screens of the example, it
seems that it's not hard to produce that.

What would also be nice is some way to simply generate plain ascii text
versions of the FAQ as well, along with possibly some other versions. We
could also think about generating DocBook SGML (which then can be
converted in a lot of different formats with for instance the Linux
SGMLtools 2.0).

I haven't given too much thought to collaboration mechanisms. It would
be useful to have the ability to easily move questions around in the
list from one section to the other. My plan is to early on just get any
question/answer pairs we can come up with (from mining the mailing list,
documentation, and whatever people contribute). Later on we can then
organize these in categories, once the pattern becomes clear (likely
we'd have a DMTL section, for instance, and an installation section). If
there's flexibility in moving questions around the FAQ might be
developed more quickly. 

People could contribute question/answer pairs (or just questions) in
some 'contribution area' and the managers of the list can then edit
these and move them to the right sections of the list after doing so.
The contribution area should still be visible for everybody, so that
even the raw entries can be useful. I'm brainstorming right now, so
here's another idea: if someone sees a question in the 'contributed'
area that he knows the answer to, that person should be able to write in
an answer. Even with the already edited questions in the main list it
would be useful if people could leave comments ("I tried this but it
didn't work for such and such reason. But if I did this and that, I got
it working."). The editors can then later review all that's added and
integrate it into the main text.

Right now I intend to just assemble a big raw plaintext file (structured
text!), though; anyone can work with these. It's good to keep the
process moving.

Regards,

Martijn

As long as the *me too!* message doesn't include the entire previous

I have no DNS, it's a local system only. I'm using Windows 95 and this
doesn't work. But it should no problem to "fix" the ftp_server. The
IP_ADDRESS could set in start.py and this address is used by the
http_server module, but not by the ftp_server module.

Using the "in" tag's grouping capability, is there any way to get the count of
items in that group? I need this so I can have a table with one row per item
and a cell rowspanned for all the group's items (eg: related products and their

Message-ID: <01E40461E003D21195CC0080296495D80B12B3@gates.cdc-group.com>

While debugging a Product that inherits from OFS.Folder stumbled across
the following problem (copied from the debugger command line stopped
inside one of my Product's methods):

>>> self.__class__.__bases__[0].__bases__[3].__bases__[1]
<class OFS.CopySupport.CopySource at 8d11e0>

>>> isinstance (self, OFS.CopySupport.CopySource)
0

>>> (self.__class__.__bases__[0].__bases__[3].__bases__[1] 
     is OFS.CopySupport.CopySource)
1

The first line says self is an instance of OFS.CopySupport.CopySource,
the second says it's not. The class objects are identical.

My problem is that I'm not able to override one of 
OFS.CopySupport.CopySource's methods and to call the
base classes method from inside. At that point I get
a 
    TypeError: unbound method must be called with 
               class instance 1st argument

which usually occurs when calling an unbound method with
an instance of the wrong class.

I'm clueless..

No, there isn't. You will have to use the SQL statement, to add a calculated
value column to it's output. You should be able to use COUNT to achieve this.

Actually this example shows the beauty of Zope/Bobo programming -- the
code looks completely like normal Python code, no CGI hackery involved.

Anyway, this is really a Python question, IMO.  You don't the arguments
to the Child's constructor to be hardwired in the Parent, right?

You could take a route where pass a dictionary, e.g. REQUEST, into the
Child's constructor and let it figure out for itself what it needs.
This feels less OO and doesn't let Zope/Bobo help you with type
conversions and raising exceptions for missing arguments.

Good timing.  We are planning a Collector Day At The Beach pizza party
on Friday.  We'll gather everybody together for a couple of hours,
discuss a bunch of submitted issues, and try to clear them out.  I'll
articulate a policy on support within a week.

We still haven't emerged from our network hell -- our dedicated line
hasn't been installed yet -- but things are slowing getting under
control.

Count me in as well.  I'm meeting with some folks today to get a Zope
training course scheduled.  I'll create the preliminary docs which they
will improve and use for the course.  Thus I'll have some some material
for a (perhaps four day) training course to contribute.

BTW, is there any interest here in a Zope training course?

Subject: [Zope] [ZDP] Assorted FAQs
Message-ID: <36DD3FD7.F71EAE80@pop.vet.uu.nl>

Hi everybody,

Here is a start. I just randomly browsed the mailing list and created a
completely uncategorized set of questions and answers for the FAQ. I
even snuck in a question of myself, see if you can answer it. :)

If you see a problem with some of these questions or answers, send a
followup with suggested corrections to the list and I'll include them in
the FAQ. If you have more question/answer pairs, go ahead and followup
too. I prefer these things to appear in the list (in a thread, and
marked by [ZDP]) for now, as this might stop people from writing the
same FAQs twice. I hope in a while we'll get somekind of collaborative
FAQ environment going that makes all this easier.

I'd prefer additions to the FAQ in StructuredText for now. See what
follows for an example of the format I have in mind. If you think
another format works better feel free to convert. (yes, that's the theme
of open source; if you want something done differently, feel free to do
the work to change it :).

Here's what I have so far, enjoy!

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use:

        &lt!--#var "external_method_name(arguments)"--&gt
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is:

        &lt!--#var expr="external_method_name(arguments)"--&gt

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

Well, the underlying issue is the stateless-ness of the whole thing. In
normal python, you'd create an empty child, call the child's editing form
so the user can enter initial data, and only after the user's commit add
the child to the container:

def addChild(self):
     newChild = Child()
     if newChild.editForm() == true:
        container.append(newChild)

in short. I've attempted this in the ZPublisher environment, but to no
avail - either it didn't work at all or it got very messy (with the Child
needing to know about the Parent, etcetera).

I must say, I was under a bit of time pressure last night when looking for
alternatives (wanted to have a beta release on my website before
breakfast), I haven't got around playing with hidden form variables
etcetera yet - that could work. Just hoped somebody on the list here would
have a canned answer - I'm a lazy guy ;-)

Subject: [Zope] Some tough questions about zope... (long)
Message-ID: <v0410440eb302e9edd947@[128.240.198.13]>

Hi all,
This is quite a long email where I ask a lot of questions about Zope, 
but I hope you'll be lenient with me as I think I have a few hard 
decisions to make!

Some background:
I'm one of the web developers here, with a remit to implement a 
curriculum database that can;
(a) support the Medical Faculty here
(b) get rolled out to three other Medical-related sites, each with 
their own 'look and feel'
(c) possibly implement a University-wide curriculum database.

The curriculum database is essentially delivering online study guides 
(over 100 for each Faculty) whose source is originally from very well 
marked up Word Documents. In addition, we include multiple choice 
questions, file upload of lecture notes etc. and some 'active' web 
pages showing dynamical processes in medicine etc. The curriculum 
database needs to be searchable across its entire breadth (although 
initially restricted to the one site), so that students and faculty 
can find occurences of, say, 'lung cancer' in lecture resources - 
this is to plan for curriculum management, so that we can find out if 
we're pushing subjects too much (or indeed, whether we're pushing a 
subject at all!). We have other applications (nearly all of which are 
written in Perl/PHP3) and want to seemlessly integrate them into the 
curriculum database.

Currently we do all our development work on Unix, using Apache 
virtual web servers, MySQL as our database engine and Perl running as 
a CGI for most of our applications. My input has been to introduce 
PHP-3 (an Apache module with a bulit-in XML parser) and some XML 
knowledge to the group. I've been looking at a scenario where our 
study guides are converted in XML using Omnimark and held as static 
XML documents in a database. They are then rendered into HTML/RTF and 
put into static web directories. The student can run a program that 
extracts elements from selected XML documents and creates a 
customised set of HTML pages or RTF document that is built for them 
'on the fly'. My manager was a bit worried about all these static 
pages lying about and to be honest so am I, but extracting the 
relevant XML from a database to render into individual HTML pages 
seems a massive drain on the system.

I found out about Zope Monday morning, dl'ed it, installed it, got 
one or two things working... and have been worried sick ever since.

My problem? is that I can see how Zope can do so much for us, but it 
seems to need a hell of a gut-wrench to do so.
There also doesn't seem to be an easy 'half-way' house to move to Zope.
I've read a lot of the documentation, and am doing so constantly, but 
the wisdom of the list would be very helpful indeed.

The questions:
a) Is there a way for us to 'dump' the non-dynamic parts of a Zope 
database into static HTML pages. This would act as a way to say to 
the team "look, we have a parachute!".
b) Can I integrate with the Perl/PHP3 programs that we have (the Perl 
programs are mainly .cgi, but the PHP3 programs are server-side 
scripted, and as such are embedded into the HTML itself). This is so 
that I can
c) Is there any way of using the XML documents that I'm creating into 
the database and parsing them to produce either HTML or RTF output?
d) I know that this a terrible question to ask... but is Zope likely 
to 'remain' open-source (we're worried about getting stuck with a 
proprietary system)?.
e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
dropping the :port requirment).
f) I'd like to have the option to have user authentication 
information coming from a database - is this possible?
g) We have something like 200 main level directories holding the 
study guides, each with up to 200 files in them - is that pushing the 
Zope database too far?
h) We also need resources such as QuickTime movies, images PowerPoint 
slides etc. to be uploaded - would they sit in the database or can 
they be held somewhere else (and what happens about file name 
conflicts)?
i) Does Zope have the equivalent of 'server logs', which we use for research.
j) Is it possible to have a 'pointer' at a location in the Zope 
database that will point to a 'real, honest to goodness' HTML file on 
the server (ie something like a redirect..oops I think I may have 
answered my own question)
and lastly
k) What kind of loads have people put Zope under (10,000 +hits a day, 
100k?). We have one application which has 170 Medical Students 
sitting in front of screens and clicking a button at the same time 
(they're selecting their final year options) which then starts 170 
CGI-based Perl processes off interrogating and updating the database. 
This really grinds the system down...

I hope that I haven't bored everyone to tears here - it's just that 
Zope seems to do an awful lot of what I need, and I'd really like to 
know what I'm letting myself in for if I start using it for 
everything I do....

many many thanks,
tone.

Cookies or passing around secret messages would be the way to avoid
this, don't use Basic authentication at all.  The UserDB product shows
off a User Folder than uses cookies, and possibly today I am releasing a
User Folder product that authenticates off of a flat file, like
/etc/passwd for alpha testing which also uses either Basic or Cookie
auth.  If you use Cookie auth you are presented with a login/logout
screen to set/clear the cookie.

Message-ID: <199903031517.HAA31270@hipmail1.gohip.com>

Thanks for the help, but...

My problem is a little bit harder than that. The data in field2 is date *and* 
time. So like this:

field1 field2
------ ---------------
red    3/1/99 10:00 AM
blue   3/1/99 11:00 AM
green  3/1/99 03:00 PM
brown  3/2/99 10:00 AM
yellow 3/2/99 04:30 PM

I've seen in the guide where you can format a data field when outputting, but 
how do actually extract the day-of-the-month number and put it in a temp 
variable. The pseudo-code I've used before to do this before is:

tempday = 0
for each record
  if tempday<>dayofmonth(datefield) then
     print out a header
  print out other fields
  tempday = dayofmonth(datefield)
next

I'm just having a little trouble translating that into DTML. Creating a simple 
temporary variable seems overly complicated.

If you continue to use it you will get the Zope Zen. :)

This begs the question we've asked around here so many times, 'What is
data?'  Everything in Zope is Dynamic, in my thoughs, 'non-dynamic' is a
Document with not DTML in it.  But there is no way for Zope to sniff a
document and see if it contains dynamic structures or not.  Perhaps what
could be done is to write a simple MyDocument that you stipulate in
policy never to have dynamic stuff in it, and then write a crawler
scripts that sucks out all such documents into a local file structure.
There maybe easier solutions.

...do what? ;)  Zope can call your cgi scripts just like they are, as
URLs.  They would, of course, have to be external to Zope and if you
have a bunch of little ones you may find it better (and a damn sight
easier) to rewrite them as Python in Zope as external methods. (DTML is
also a rather powerful language for being so simple).  Just leave your
PHP stuff in your documents; Zope will parse out the DTML and return it
to the server, which will parse out the PHP stuff and return it to the
browser.  In fact, you can probably make DTML and PHP work together
nicely and simplify much of your PHP code.  In the quickie case you
don't need to change your PHP.

> c) Is there any way of using the XML documents that I'm creating into

Zope doesn't contain an XML parser.  You would need to do this with an
external package.

Yes.

Yes.

Yes.  There is an unsupported open source User Folder Product called
UserDB, where you tell it how to query your DB and it uses that for
authentication.

Not at all.

ooo.  Someone has yet to write an ExternalFile product (though I suspect
it would be fairly simple) to add objects to the db that refer to files
outside the db.  For now you can upload them as File objects to be
contained entirely in the db.  The same rules that apply to file name
conflicts in, say, a UNIX filesystem, apply to the Zope db.  You can't
have the same object id in the same folder. (With a minor non-exception
of aquisition, all lower folders can see the contents of higher folders,
but if you place an object in a lower folder with the same id as an
object in a higher folder the lower object will override the higher
object.  Get that?)

> i) Does Zope have the equivalent of 'server logs', which we

Since Zope is served through a web server you can continue to use the
server logs.  In other words, No. ;)  Object by Object logging is
something we've discussed, but would require *a lot* of thought and
work.

If that file is being served up by Apache then you can just use it's URL
as a 'pointer'.

Ah yes, the inevitable benchmarking question.  There are lots of issues
here, memory footprint vs processor speed vs concurrent access...etc.
The quick word is, Zope is fast and it will get much faster.  Zope is
currently not concurrent but will be in 2.0.  Zope+Apache is a bit slow
due to the pcgi bottleneck and is much improved by using ZServer.  As it
stands now, ZServer is something like twice to 10 times faster than
Zope+Apache.  Medusa (the web core of ZServer) serializes the requests
into Zope at the moment, but when 2.0 comes out it will be the fastest
web application platform on earth.  Don't quote me.

I will be looking into this, as soon as I have the time. The answer for now is:
probably, because everyone wants to download a local copy of part of any
website at some point. There are tools out there to do this, I haven't looked
for them yet.

Just run Zope via Apache (see below).

Python is very capable of parsing XML. You will have to write an External
Method to handle this, though. An example of XML parsing can be found at
http://www.zope.org/Download/Contrib/XMLConfig.tar.gz. This Zope Product parses
a static XML file for use in Zope.

I certainly do hope so. I intent to use it en expand on it heavily anyway, and
sodo others. These extensions will generally be Open Source themselves, making
it hard for Digital Creations to pull Zope out of the Open Source domain.

>e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
>dropping the :port requirment).

Yes. The doc/WEBSERVER.txt will start you on this. Be warned though, there are
some problems with Apache and Zope integration, for reasons that others are
better equiped to explain.

>f) I'd like to have the option to have user authentication 
>information coming from a database - is this possible?

Yes, you can find the UserDB Product at
http://www.zope.org/Download/Prereleases/UserDB/UserDb-1.2.0-nonbin.tar.gz.

>g) We have something like 200 main level directories holding the

Nah, Zope has handled much more than that allready. Ask Paul =).

Zope can store any filetype you want it to. Filename conflicts are handled the
same way a filesystem handles them: In the same Folder, you cannot have two
objects with the same name at once. But because it is a hierachical system, you
can use the same name in two different folders.

>i) Does Zope have the equivalent of 'server logs', which we use for research.

ZopeHTTPServer's output is it's serverlog. You can start it up with STDOUT
redirected into a file. When you use Apache as your webserver, all requests
will be logged through Apache itself.

You said it yourself =).

Zope will be much much faster. I can't give you any direct numbers, maybe
someone else on this list can. You basicly don't have the overhead of starting
a fullblown new process for every request, and Zope pools Database connectiosn
for you, so you don't have the initial connection overhead either. And, your
code isn't compiled everytime, like with Perl.

I know the feeling. I was choosing between ColdFusion and Zope for
developing my new application and had some similar questions. Ultimately,
I chose Zope.

[nice application description deleted]

| a) Is there a way for us to 'dump' the non-dynamic parts of a Zope

| the team "look, we have a parachute!".

Right now, there isn't. This question has come up repeatedly on the list,
to the point where DC is getting sick of hearing it and thinking of actually
implementing something :)

They have said it would be pretty easy, and I believe it. I think 
the basic idea is to write a method that will go through the Folders and
use the DocumentTemplate code to render out the pages.

| b) Can I integrate with the Perl/PHP3 programs that we have (the Perl 
| programs are mainly .cgi, but the PHP3 programs are server-side 
| scripted, and as such are embedded into the HTML itself). This is so 
| that I can

If you're using Zope with Apache, you use mod_rewrite to get the
authentication headers passed to Zope. You can also use mod_rewrite to
decide how URLs map to content on your server. For example, you can
have all of the content on your site go through your Zope.cgi, but
/cgi-bin/* can go directly to your CGI or PHP files. You can access
MySQL from Zope, PHP and Perl, so they can all use the same data
source for the databases.

| c) Is there any way of using the XML documents that I'm creating into 
| the database and parsing them to produce either HTML or RTF output?

I'll leave this one to people more knowledgeable about XML.

| d) I know that this a terrible question to ask... but is Zope likely 
| to 'remain' open-source (we're worried about getting stuck with a 
| proprietary system)?.

I think it would be tough for DC to try to take it back at this point :)
Even if DC did decide to not release any more updates to Zope, the community
would probably continue working from the 1.10.2 code. Anyhow, DC had
sound business reasons to release Zope as Open Source. Over time, they
will likely get a lot of benefits by having done so and by encouraging
outsiders (like us) to work with and improve Zope.

| e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
| dropping the :port requirment).

Yes. This uses a technique called Persistent CGI. It works quite well.
There is also a hope that there will be better integration with Apache
in the future. Also, as ZServer stabilizes, you may find good reason to
migrate from Apache to it.

| f) I'd like to have the option to have user authentication 
| information coming from a database - is this possible?

There is an unsupported bit of code called UserDB which is designed for
this.

| g) We have something like 200 main level directories holding the 
| study guides, each with up to 200 files in them - is that pushing the 
| Zope database too far?

Though I have no first hand experience with a Zope DB this large, the
DC guys have said that they've worked with some very large DBs.

| h) We also need resources such as QuickTime movies, images PowerPoint 
| slides etc. to be uploaded - would they sit in the database or can 
| they be held somewhere else (and what happens about file name 
| conflicts)?

You could put them in either place. There would probably be some
advantages to putting them in the database. For example, your standard
Zope security rules will apply to the downloading and updating of the
files.

| i) Does Zope have the equivalent of 'server logs', which we use for research.

I don't know about ZServer, but if you use Apache as your web server you
will be able to use your standard server logs.

| j) Is it possible to have a 'pointer' at a location in the Zope 
| database that will point to a 'real, honest to goodness' HTML file on 
| the server (ie something like a redirect..oops I think I may have 
| answered my own question)

Yes, you can do a redirect.

| and lastly
| k) What kind of loads have people put Zope under (10,000 +hits a day, 
| 100k?). We have one application which has 170 Medical Students 
| sitting in front of screens and clicking a button at the same time 
| (they're selecting their final year options) which then starts 170 
| CGI-based Perl processes off interrogating and updating the database. 
| This really grinds the system down...

I've heard it said that Zope should be able to handle 500k hits or more
on reasonable hardware. Of course, this depends on exactly what the
server has to go through for each of those hits, etc. DC is also working
on concurrency for Zope 2.0. This will probably enable you to handle a
whole bunch of requests.

Good luck!

You'll have to use SQL function for this. In MySQL you could do the following:
SELECT field1, DATE_FORMAT(field2, "W, M d") as datefield FROM MyDB.

Put this in a Z SQL Method, and then the following DTML will get you your
results:
<!--#in MySQLMethod sort=datefield-->
  <!--#if first-datefield-->
    <!--#var datefield-->, 
    <BLOCKQUOTE>
  <!--#/if-->

  <!--#var field1-->

  <!--#if last-datefield-->
    </BLOCKQUOTE>
  <!--#/if-->

<!--#else-->

Everybody on this list is lazy ;-)

This is my approach:
First define a Webobject class that every object needs to inherit. The
simplest could be just:

class WebObject:
	        
    def __init__(self,name):
        '''__init__(self,name)
        '''
        
        self.name=string.replace(name,' ','_')

    def _set_root(self,root_obj,parent_path):
        '''_set_root(self,root_obj,parent_path)

        sets the root object and relative path. Note: 
	one will never need to pass parent_path directly. I also need
	to have a reference to the root object so I can do stuff remotely
	similar to acquisition'''

        self.root=root_obj
        self.rel_path=parent_path+self.name+os.sep

class Container(WebObject):

    def __init__(self,name):
        WebObject.__init__(self,name)
        ##Holds contents
        self._d={}

    def __getitem__(self, key): return self._d[key]

    def items(self): return self._d.items()

    def _do_add(self,object):
        '''_do_add(self,object)

        Adds object in container. Object MUST have inherited the
        WebObject class.'''

        name=object.name
        if hasattr(self,name) or self._d.has_key(name):
            raise ValueError,'Object with same name exists in WebFolder'
        d=self._d
        object._set_root(self.root,self.rel_path)

        d[name]=object
        self._d=d

So you can create any object that has inherited the WebObject class
independently and add it to the container instance.

Subject: [Zope] [ZDP] Tree FAQs
In-Reply-To: <36DD3FD7.F71EAE80@pop.vet.uu.nl>
Message-ID: <4.1.19990303153836.00a64c50@lisp.atmm.nl>

My two cents on the tree tag:

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute of
    the tree tag. The objectValues function of a folder returns all objects
    contained by that folder. 

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML 
    Document objects in a Folder. Other metatypes you could select on are:
    Folder, DTML Method, File, Image, Mail Host, User Folder and Session.
    This is not a complete list, as Products can and will define their own
    metatypes. If you want to show more types, just add them to the list,
    like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        &lt;!--#tree branches_expr="objectValues(['Folder'])"--&gt;
	    &lt;A HREF="&lt;!--#var URL1--&gt;/&lt;!--#var id--&gt;"&gt;
            &lt;!--#var title_or_id--&gt;
            &lt;/A&gt;
	&lt;!--#/tree--&gt;

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a tree, is
    called with ?expand_all=1, the tree tag will expand all it's branches.
    Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand 'buttons'::

        &lt;A HREF="&lt;!--#var URL0--&gt;?expand_all=1"&gt;
          Expand all&lt;/A&gt;|
        &lt;A HREF="&lt;!--#var URL0--&gt;?collapse_all=1"&gt;
          Collapse all&lt;/A&gt;

        &lt;!--#tree--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        &lt;!--#tree single--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;


More cents will follow.

This sounds like something we need.
I know that I could use it.
If folks will critique this design, I'll implement it.

- - Proposed Access Method - -
It is desired to be able to have "non DTML" files incorporated
in a Zope URL system. These files might be static GIF files,
quicktime movies, or just plain old HTML.

Obviously, they might be "included" in a DTML page by simply
referencing them directly by their URL. However, I can see cases
where one would like the access to be under the control of the Zope
system.

For example, access controls might apply.

I believe that we can achieve this by having an object
which represents an ExternalFS mount point.

In general, we map a URL onto a node of the FS.
It would be directly analogous to a symbolic link (ln -s).

The Zope mount point would enforce permissions just as if the
file were loaded into the Zope DB.

Objects can be "imported" without having them take up space
in the database. Their creation and maintanence can be handled
outside the Zope system.

They are rendered by "cat"ing their contents.

By permitting substitutions in the link, we can create effective
reformatting of the visible FS.

As an example, I am monitoring customer traffic. "mrtg" automatically
generates graphs for each customer.

In Zope, I could create customized displays by importing these files.

By using the ExFS, I can update the graphics without affecting Zope.

Further, assuming
 /mygraphs/today/customer1.gif
 /mygraphs/today/customer2.gif
 /mygraphs/yesterday/customer1.gif
 /mygraphs/yesterday/customer2.gif 

we can map them onto

somewhere/KustomerA/graphs/today
somewhere/KustomerA/graphs/yesterday


by substituting a property of the Kustomer

- - - 

Thoughts and/or suggestions?

Time to move this to zope-dev?

anyway, I think this sounds like a good idea. It harkens back to an 
inquiry I made about byte-serving PDF files. I don't want to dump my 
pdf's into the database.

If you can implement this, I think I could implement byte-serving.

Although byte-serve could be handled at the ZServer level, I think for 
large external files it'd be more effective at the "cat" level

This is a good idea. I can see this FAQ growing very, very quickly.
So, I would suggest that we start thinking about a hierarchy

| 

Installation
* building
  * win32

  * ZServer

I'm not sure if there will be many platform specific issues after

How safe would it be, to allow any random user to use the add menu to create
arbitrary symlinks into the native file system tree?

Rather than using rowspan, use nested tables. I haven't done this in
Zope yet, but it was always my solution of choice in ColdFusion. It also
makes it easier to debug your layout in a WYSIWYG editor. It does, of
course, bloat your HTML a bit.

It will work, and I'm going to have to in the short term, but I really would
like the multiple columns for each item to line up down the page, without ugly
fixed-width hacks.

Maybe by splitting up the FAQs we could split up the work, too! Have a
different person/group resposible for each FAQ.

Of course there would be nothing stopping some energetic type being
involved with all of them :)

Also, I think that HOWTOs of the Linux type would be a great idea. They
have a person/group responsible for each HOWTO to keep it up to date and
add/edit things as needed.

I am just commenting from the sidelines. Right now I barely have time to
scan through the zope-list!

Well, I think it'd be nice if there was someone "responsible" for each

You can find a "howto" LaTeX stylesheet in the Python CVS checkout, and
I'm sure Guido/Fred wouldn't mind us using this.  It works real well,
and can target HTML, ASCII (I think), Postscript, PDF, etc... this lets
you do the "bigger" stuff in a nice pretty way. 

What would also be nice is a list of "bigger" issues that people would
liek to see explained more... something that's more than a single
question.

Ok, I found:
http://www.python.org/doc/howto/writing.html
the link on that page:
you can grab [Fred Drake's documentation 
distribution], and use...
Is broken with a "Error 404: File Not Found"
Searching for "LaTeX CVS" didn't quite get it
can you please provide the links?

Not only will this be good for the DOC project
but also for general use in targeting HTML

Message-ID: <613145F79272D211914B0020AFF6401907BACC@GANDALF>

Greetings,

(This is crossposted because it is a product anouncement, and contains
interesting developer pointers)

I've have massaged the source code for UserDb and created a new user
folder products called etcUserFolder.  This products authenticates off
of a flat file of usernames:cryptedpasswords.  If there is anything
trailing the crypted password it is ignored, so any /etc/passwd file
will work.  It is generaly not recommended, however, to use your
/etc/passwd file for security reasons.

This is an unsuported product and has been written because it was asked
for a few times, and I felt the community could use another good example
of writing user folders.  It also shows off cookie authentication which
Brian perfected with UserDb.  Here is the documentation:

etcUserFolder requires a directory called 'etcUsers' in which to place
your file containing the uid:pwd pairs.  This directory may be an
INSTANCE_HOME (typicaly your top level Zope dir), SOFTWARE_HOME
(typicaly 'lib/python') or in the etcUserFolder directory.  Jim wrote a
nifty function called getPath that sniffs all of these places for a
directory and file of your choosing.  This function is included in
etcUserFolder and will be included as a standard function of the next
release.  Other Product authors may find it interesting.

Since the flat file is meant to be b/w compatable with /etc/passwd and
htpasswd style files, there is no Role associated with the users it
authenticates.  You can specify a default role which is, by default,
'etcUser'.

I have not done extensive testing of this, therefore it is a
pre-release.  Please send bug-reports and hopefully a patch to me

Message-ID: <v04003a03b3034df988d1@[192.168.1.190]>

I just upgraded to 1.10.2 and I noticed that when creating a new document I
have a choice of DTML document and DTML method. This seems useful. I
noticed that all my DTML documents and DTML methods have the icon for a
DTML method. Everything seems to work.

What is the difference between a DTML document and a DTML method? Seems to
me a method should not be surfable but they are.

Is it possible to change my documents to DTML documents? Even just for
housekeeping.

One other unrelated question: What is a Principia Draft?

I just had a quick exchange with Fred Drake (who handles most of the
documentation duties for the Python organization), and he is aware of
this problem, and has forwarded the issue to AMK who is responsible for
teh HOWTO stuff.  IN the mean time, he suggests grabbing the latex
documentation whihc will have it all in it.  If this is too painful, I
can post a snapshot of the pieces taht are needed from the current CVS
repository.

The URL for the LaTeX documentation is:

I would love to see this feature (generating DocBook SGML). I thought
about something like this myself (for my howto), but I just don't have the
time at the moment. I could probably find enough time to help out a little

Message-ID: <36DDA463.683D9460@avalongroup.net>

Hi,

I'm playing with Zope, and have been trying to get Zope to talk to MySQL
using the MySQLDA.

I'm running RedHat 5.2

Since there were caveats about having MySQL development enabled, and
such, I downloaded the source distribution for MySQL and made it. It
appears to be working very nicely.

When I follow the procedures outlined in the README, the following
happens:

I run make -f Makefile.pre.in boot and everything works correctly.

I then run make and get the following error.
gcc -fPIC -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5
-DHAVE_CONFIG
_H  -I/usr/local/mysql/include -I/usr/include/mysql -c ./MySQLmodule.c
./MySQLmodule.c: In function `pythonify_row':
./MySQLmodule.c:238: warning: assignment from incompatible pointer type
gcc -shared  MySQLmodule.o  -L/usr/local/mysql/lib -L/usr/lib/mysql
-lmysqlclien
t -lm -o MySQLmodule.so
ld: cannot open -lmysqlclient: No such file or directory
make: *** [MySQLmodule.so] Error 1

I did a locate on mysqlclient, and coudln't find the file. though I did
find some called libmysqlclient. So I changed the both Setup and
Setup.in to reflect that other name. however, I still get the above
error.

Any help would be greatly appreciated.

Your problem wasn't with the library, -lmysqlclient refers to
libmysqlclient (think of the -l as short for lib). The problem probably
was that libmysqlclient wasn't on the path gcc searched for libraries.
This is controled by the -L argument (-L is library paths). 

So... here's what to do:

1. Get everything cleaned up (ie. back in the condition after first
   untarring ZMySQL).
2. Edit Setup.in, add -L<the path to libmysqlclient> to the end of the
   last line.
3. Proceed as usual (make -f Makefile.pre.in boot; make)

If this would work (having Apache parse the PHP code in the pages returned by Zope), you would save me a lot of painfull converting working PHP code (mainly database related) and I would gradually convert from PHP/Apache to Zope/Python/Apache.

Pleaz tell me how this neat trick is done... (maybe some fiddling with the headers???)

Hint:
Creating a DTML Document/method with the following contents doesn't fool Apache in rendering PHP!

<!--#var standard_html_header-->
<h2>Give me the (PHP) money...</h2>

This is my take on the situation.  As far as I can tell this is pretty
deep voodoo.

A DTML Method is what used to be just a Document in pre 1.10 releases.
DTML Methods are not objects, they are methods.  If you have a folder
called foo, and it contained a DTML Method called bar, then bar is a
method of foo.  foo doesn't contain the object bar, it has the method
bar bound to it.  What this means is that from bar's point of view,
'self' is a Folder object, and any properties it sees are properties of
foo, not itself.

DTML Documents are Zope Objects.  Their idea of 'self' is themselves.
They are contained in folders, but are not methods bound to that folder,
they are instances of DTMLDocument.DTMLDocument.  They can manage their
own Properties (because they inherit PropertyManager.PropertyManager).

Both DTML Documents and DTML Methods can hold DTML and content.  The
difference is subtle.  DTML Methods would be used when the answer to the
question 'Am I showing some other objects content through me?' is Yes.
DTML Documents should be used when the answer to the question 'Am I the
content I want to display?' is Yes.  DTML Methods have the advantage
that they don't have any properties, and their perspective of aquisition
is from their containing folders point of view.  DTML Documents have
properties which may interfere with aquisition you'd want to do, and
aquisition is from their own point of view, which may not be what you
want.

(BTW Martijn, perhaps the above should go in the FAQs)

If this isn't clear to you don't worry, it isn't even really clear to
me.  There is no way, but there really should be a way to convert
between the two because the roles for a DTML widget may change from
Method to Document as your system evolves.  This will probably be a
feature in the next release.

(This is the answer to the question 'Can I convert between DTML Meths
and DTML Docs?' for the FAQs)

You almost made it ;=)
The -lmysqlclient does refer to the libmysqlclient you found, but you should only modify the path pointing to it. This is done in the Setp[.in] just before the -lmysqlclient; modify the '-L/<path-to-the-libmysqlclient>', if have this set to -L/usr/local/lib/mysql.

[ZDP] Maybe this is something for the FAQ?

This can't be done currently. I researched this a while back, trying to
get server side includes to work. There's actually an entry in the Apache
FAQ about it:

"""
9.How can I have my script output parsed? 

     So you want to include SSI directives in the output from your CGI
     script, but can't figure out how to do it? The short answer is "you
     can't." This is potentially a security liability and, more
     importantly, it can not be cleanly implemented under the current
     server API. The best workaround is for your script itself to do what
     the SSIs would be doing. After all, it's generating the rest of the
     content. 

     This is a feature The Apache Group hopes to add in the next major
     release after 1.3. 
"""

Though this is about SSI, it basically means (I believe) that apache can't
take back the output of a CGI for additional module handling.

Hi  Sture,
try to use the P MySQL Input wizard in the contrib download area. It
will automatically create a insert sql method and a form for you. So you
can just follow the pattern.

<a nice dissertation on variable indirection, which I now understand>

I'm piggy backing this on Amos's post from a while ago, because that is
where I finally found my answer. I could have sworn I had seen (and
used!) a DTML code fragment that displayed the form variables sent to
it, with there values. Obviously, this involves indirection. 

After hunting through my (extensive) zope-list archive, I couldn't find
it, so I started over, with the help of Amos's text and wrote one. I
often need little tools like this to debug between my forms and sql
actions, so I can see what's really going on!

I call it 'show_vars'

The only tricky thing in it is that sequence-item is an invalid variable
name, so I need to wrap it in _[''] which leads to the double wrap when
dereferencing to get the value. Anyway, hope someone else finds it
useful!

I haven't tried it, but it could possibly be done by running two
Apaches: one which stands "in front of" the other.  The front-side
Apache would rewrite every access into a PHP wrapper-script which
include()s a corresponding URL from the back-side Apache where the
Zope things would be done.


On the other hand, I really should be asleep now so all this _may_
be utter nonsense, but I do think it's possible.  It may even be
possible with a single Apache, but that's more hairy than I dare think
about right now.  Good night.

(Btw, my suggested hack isn't in total disagreement with the quoted 
FAQ entry, because my hack surely won't work with SSI.  PHP3 isn't an
official Apache module, so they don't neccessarily mention things like
this in their FAQ.)

I'm attempting to use ZServer's ftp daemon to upload a number of

I've tried this with an image that doesn't exist, as well as for one
that already exists. Is it just a matter of "it doesn't work for images"
or what? Also, where does ZServer send errors from ftp sessions? It looks
to me like it's just silently eating them. :(

In all the world you might find 4 machines still plugged in that
support 'record' or 'page' structure.  The default is 'file', which is
what that command is trying to do.

Add these two methods to ftp_server.py::ftp_channel

    def cmd_stru (self, line):
        'obsolete - set file transfer structure'
        if line[1] in 'fF':
            # f == 'file'
            self.respond ('200 STRU F Ok')
        else:
            self.respond ('504 Unimplemented STRU type')

    def cmd_mode (self, line):
        'obsolete - set file transfer mode'
        if line[1] in 'sS':
            # f == 'file'
            self.respond ('200 MODE S Ok')
        else:
            self.respond ('502 Unimplemented MODE type')


And that should do the trick.

Micheal answered these perfectly.

>One other unrelated question: What is a Principia Draft?

It is a special use of the session object, but it appears to be partially
broken. When you create a Principia Draft, it asks you to specify an
orginal object, from the same Folder you are creating the Draft in. This
will be your 'draft', on which you can make changes invisible to the
outside world.

The draft contains an invisible Session object that is immediatly started
and joined, and an invisible UserFolder to facilitate extra users (for
example, customers that want to be able to view your work on it as well,
but have no access to it otherwise).

The Principia Draft suffers two problems however. The first is really a
Session object bug, in that security for Session objects is broken. This
has allready been reported as a bug to the Collector by me. The second
problem is that the Userfolder and Session controls are inaccessible via
the management screens.

The latter problem is caused by convention changes in the Folder object (or
the ObjectManager class really, used by Folder. I think that Folder objects
_used_ to call title_and_id on a object when displaying it in it's
management screen, but the current release of Zope constructs the id and
title of an object by using it's id and title separetly. Principia Drafts
made use of the call to title_and_id to insert links to its UserFolder and
Session controls. As this now doesn't happen anymore, you will have to do
this yourself.

As long as you have access to Session objects, you can change users on a
Principia Draft object by calling it's users__draft__.manage_main method,
and reach the Session controls by calling its manage_approve__draft__
method. The URLS are:
http://yoursever.com/Zope/Draft/users__draft__/manage_main and
http://yoursever.com/Zope/Draft/manage_approve__draft__

   As far as I understand there are DTML objects (templates), Products and
External methods. There is no such thing as "Internal" methods (objects,
that live in Zope's object database). Are these 3 the only 3 kinds of
executable (callable) things?

    By using the #in tag, you can easily all show all data in any dictionary
    object, like REQUEST.form, REQUEST.cookies and even REQUEST itself. Just
    call the items() method of the dictionary, and the #in tag will provide
    a sequence-key and sequence-item variable for every item in the
    dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>
        <!--#/in-->

    Use REQUEST.cookies.items() for all your cookies, and REQUEST.items()
    for all REQUEST variables, including CGI Environment variables.

I'm randomly assuming here you know more about DocBook SGML than I do,
so here I'm involuntarily inofficially  but you can back out of it
immediately appointing you the ZDP DocBook SGML expert. :)

I think perhaps the first thing you could do is get together with people
in the Latex thread for docs; they seem to have come up with it
independently. I know even less Latex than SGML and SGML seems a closer
fit with the XML-ish direction the web's taking, so my question would be
to point out the advantages of SGML to everybody.

[snip proposed hierarchies]

Yup, splitting up the FAQ into different categories appears to be pretty
needed, so this is a good idea. My idea is to 'involunteer' you category
maker guys to take the assembled FAQ that I'll produce hopefully today
(in a few hours), and put each question in the category you feel it
belongs to. This way I have to do less work and thinking. :)

Subject: [Zope] Bobo or ZPublisher and stdout ( Solution: Client/Server)
Message-ID: <36DE5733.60F87988@oi42.kwu.siemens.de>

Hi,

I already sent some postings to this topic, but I would like
to discuss the following problem again and how it could be solved.

Imagine there is a big C++/Python project.
The application is mainly prgrammed in C/C++ und one supports
a scritpting interface to that application via the SWIG mechanism -
the target language is Python.

During the developping process many stuff is written to the stdout -
during initialization ( before the main-function ), during execution (
in the main-function ),
and in the destructors of the static instances ( after the main-function
).

Now we want to do some web-stuff via ZPublisher, we define
a function which return a html string, which is calculated through
calling functions
from our scritpting interface of our application, that means beside my
correct
calculated string there is many stuff sent to stdout, that confuses
the Xserver and I get an error.

Ok, you would say switch the stdout to a file via calling c-funcions
like dup() or dup2( ) and
encapsulate this in a function (wrapped via SWIG), which is called in
the function which I call from
the URL in the browser.

Less cryptic:

 xy.py:

   start():
       "XXXXXXX"

        #Now all stdout goes in a file
       stdout2file( "log.txt")

        ....
       HTMLstring = ....

        # sitches the stdout back ( REVerse )
        # The way is free for CGI
        REVstdout2file()

        return HTMLstring


the URL:    http://myserver:3333/yyy/cgi-bin/xy/start

BUT with this method I have no chance to chatch stuff which is written
to the stdout
in the destrutors of the static instances, because we already have
switched back to the
"usual" stdout (for a correctly working cgi-mechnism).
The some problem one have with things which are written
to the stdout during the initialisation of the static instances.
( Imagine python itself is compiled
against a library which writes some stuff to stdout during
initialization).

I see only one solution:
If there is a ZPublisher Server process which says to a client process
do everything
and give me a calculated string via sockets or something like that, I
have not to take
care about stuff which is written to the stdout at the client process.

Or are there better solutions ?

   Thanks in advance,

    Armin

Yes, this would be a good idea. My first priority however is to get as
much of a FAQ as possible out there. Organization we'll do at the same
time. Otherwise we run the risk getting bogged down in organizing who
does what. 

That said, volunteers who want to manage specific sections of the FAQ
are very welcome to step forward. Procedure is as follows: you get to
name your topic; the first person who names a particular topic and
produces a FAQ for it (assembling it from the FAQ we have now, and
hopefully adding more of his or her own to it) will be manager for that
section, unless that person doesn't want to, of course. :)

I suggest to mail this list instead of me personally, so that other
people can respond friday and during the weekend, when I won't be around
to check the mail. We're working on getting a zdp@zope.org mailing list
too, but I can't say yet when that'll be ready.

Aren't there some HOWTOs out there already on the Zope site? (there are
FAQs too but that doesn't stop us of course). HOWTOs and FAQs of course
have some overlap; we'll just see how it evolves.

Earlier I suggested using SGML Docbook for this purpose; I've appointed
John Eikenberry (without any feedback from him :) as our official SGML
docbook expert. One advantage of Docbook SGML is that it's the new Linux
standard for writing documentation.

I think essentially a HOWTO is a particular frequently asked question
with a very long answer. :)

My rough sketch right now is a four-day course:

Day One -- Zope for Content Managers
Day Two -- Zope Programming Using Zope
Day Three -- Zope Programming Using Python
Day Four -- Relational Databases and Zope
         -- Zope for System Administrators

It would be a professionally produced and delivered "in the classroom"
class, a la Learning Tree.

That is, I won't be doing it. :^)  Instead, I'll produce a poor version
of the whole thing and give it to them, including the first customer
that will send maybe 7 people.  My poor version would probably become an
online version.

Just my thoughts currently.

I guess this counts as an announcement. Ken asked me to do it, but I
just mailed him I'd rather he did it (as he knows more about these
things than I do, and I won't be available to deal with problems until
monday, after today, thursday).

But, now you did, so that's fine too. :)

Hi everybody,

Here is the new ad-hoc FAQ. I'll start versioning it as of now; this
is version 0.1. How we'll do the actual versioning we'll still have to
decide on, but at least we have a way to refer to this one now.

Note on the use of the Zope mailing lists:

    The Zope Documentation Project is getting its own mailing list
    (zdp@zope.org). In an attempt to gain publicity and support among
    the Zope community, I'll post this development FAQ to the main
    Zope list as well, however. Feel free to respond to it on either
    list for now, but you are encouraged to join the ZDP mailing list
    and to send new FAQ suggestions there.

    You can subscribe to the ZDP mailing list by using the page:

        http://www.zope.org/mailman/listinfo/zdp

Note on the categorizing of this FAQ:

    This FAQ is a FAQ in progress. It is uncompletely unstructured,
    unrelated questions are mixed haphazardly. If you feel the calling
    to categorize the FAQ or to maintain the questions for a
    particular topic, feel free to mail your changes to the list, and
    thanks in advance!

Note on the code examples and StructuredText:

    I've reconsidered and used normal '<' and '>' characters in sample
    DTML, for the reason that at least the FAQ is readable as text
    then. If you try to feed this FAQ through::
     
        <!--#var faq.stx fmt="structured-text"-->

    there will be an error message in Zope, however. For some reason
    Zope seems to try to interprete even StructuredText that uses &amp
    escape codes. Until this issue is resolved it is not possible to
    render this document into HTML.

    In my uninformed opinion, StructuredText code examples shouldn't
    be interpreted by Zope as actual DTML. There may be some rather
    subtle technical difficulties involved however. Any input on this
    is very welcome. Until the matter is resolved, the FAQ document
    will use StructuredText in the plaintext readable way.

    Thanks to Martijn Pieters in being so considerate to supply HTML
    escaped DTML examples; it's unfortunate his efforts weren't useful
    this time.

Note on my availability:
    
    Martijn Faassen (me!), ad-hoc FAQ maintainer of the ZDP's Zope FAQ
    is generally not available to read or respond to email on friday,
    saturday and sunday. It is suggested ZDP related communication
    goes through the ZDP mailing list at zdp@zope.org anyway, and is
    not sent directly Martijn. This way anyone who wants to do
    something for the ZDP (such as editing and extending the FAQ) does
    not have to wait for Martijn to read his mail, having all relevant
    information available on the list.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like REQUEST.form, REQUEST.cookies and even
    REQUEST itself. Just call the items() method of the dictionary,
    and the #in tag will provide a sequence-key and sequence-item
    variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>

    Use REQUEST.cookies.items() for all your cookies, and
    REQUEST.items() for all REQUEST variables, including CGI
    Environment variables.

* What is a Principia Draft?

    It is a special use of the session object, but it appears to be
    partially broken. When you create a Principia Draft, it asks you
    to specify an orginal object, from the same Folder you are
    creating the Draft in. This will be your 'draft', on which you can
    make changes invisible to the outside world.

    The draft contains an invisible Session object that is immediatly
    started and joined, and an invisible UserFolder to facilitate
    extra users (for example, customers that want to be able to view
    your work on it as well, but have no access to it otherwise).

    The Principia Draft suffers two problems however. The first is
    really a Session object bug, in that security for Session objects
    is broken. The second problem is that the Userfolder and Session
    controls are inaccessible via the management screens.

    The latter problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately. Principia Drafts made use of
    the call to 'title_and_id' to insert links to its UserFolder and
    Session controls. As this now doesn't happen anymore, you will
    have to do this yourself.

    As long as you have access to Session objects, you can change
    users on a Principia Draft object by calling it's
    'users__draft__.manage_main' method, and reach the Session controls
    by calling its 'manage_approve__draft__' method. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main 

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

Hm, DTML methods can be called as well, naturally, that's why they're
called methods. They're called through URL. The DTML method then is
executed. This means executing any DTML in it and returning the
resulting HTML to the caller. One way of 'calling' a DTML method is by
using it in a form action, like this:

    <form action="your_dtml_method" method="POST"> 

(or method="GET", of course)

This does go through the browser, but it feels like you're calling
'your_dtml_method' when the user presses the submit button.

This is another way of 'calling' a DTML method:

<!--#var your_dtml_method-->

I'm sure there are more ways, and I'm a bit vague about this, so I'll
leave it up to other people to turn this into a nice FAQ. :)

Martijn

So that is what the MySQL Input wizard does. I've been meaning to look at
it. Instead of saving time by using it, I did it manually. It is not that
hard but you have to understand what is happening.

1. HTML form (eg. form_html) collects data and sends it to a DTML document
(eg input_html) (that is the only tricky concept).

For example:

<form action="input_html" method="get">
  <input name="num:int">
</form>

(That :int tag does error checking. It is optional. They are documented in
the Z SQL Database Methods User's Guide)

2. The receiving doc (input_html) calls an SQL method (eg input_sql) with
an in tag.

<!--#in input_sql-->
<!--/in-->

If you do a select after your INSERT or UPDATE you can use it between the
in tags, otherwise you can just display a message or do a redirect after it.

3. Your SQL method (input_sql) would be something like:

INSERT INTO database (num)
VALUES (
   <!--#sqlvar num type=int-->
)

<!--#var sql_delimiter-->

SELECT num, etc

You don't need to do a select but if you do don't forget the <!--#var
sql_delimiter--> between any SQL statements.

Have fun!

If you don't do anything with the returned data, a #call will suffice:

<!--#call input_sql-->

Hi.  I've been getting a lot of confusing complaints about gadfly
that turn out to be Zope bugs.  Just for the record.

ZGadflyDA doesn't support more than one db, gadfly does.
ZGadflyDA doesn't support newlines in string literals, gadfly does.
ZGadflyDA doesn't include kjbucketsmodule which makes gadfly run 10x
faster.
ZGadflyDA packages gadfly beta 0.2, whereas the current release is 1.0

I'm sure these will be fixed soon, in fact I'd offer a patch if I could

As a new zope user, and also according to my general documentation
sensibilities, 
i suspect it would be very valuable to have a catalogue of the various
special variables (like sequence-key and sequence-item) and the various
entities (REQUEST.cookies, ...) available to the DTML programmer.  There
may already be some sort of catalogues around - in which case pointers
to those kinds of resources would be very nice to have...

I think at least this part of your problem may be due to the fact that Zope
is running as a different user under IIS than it is under ZopeHTTPServer.
My guess is that it can't see your datasources since they weren't created
as 'System' datasources. Check under the windows ODBC control panel and
make sure your DSNs appear under 'system dsn', not 'user dsn'.

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the
MySQL
module to make sure it works. When I do, I get yet another error.

Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: libmysqlclient.so.6: cannot open shared object file: No

The file does exist, so I am once again stumped.

Thank you for your continued assitance.

post script:

The current usage of gadfly in Zope makes gadfly do lots of parsing as in

insert into table(a,b,c) values (1,2,3)
insert into table(a,b,c) values (6,2,3)
insert into table(a,b,c) values (1,7,3)
insert into table(a,b,c) values (1,2,8)

The "right" way to do this would be to take advantage of gadfly's
dynamic parameter/multiinsert feature executing

insert into table(a,b,c) values (?,?,?)

ONCE with dynamic parameters list

[(1,2,3), (6,2,3), (1,7,3), (1,2,8)]

which would run much faster than thrashing the parser
with the individual inserts above (with kjbuckets present).
In general dynamic parameters on repeated statements reduce
parsing and binding overhead (even for other types of statements).

However, I understand this may be hard to implement as
it would require special features for the gadfly "adapter"
not of value for the other adapters. Oh well.

Anyway, in future please post/forward/crosspost any gadfly
related issues to the gadfly list.  I just discovered a pile of
complaints on the zope list this morning and I found it
distressing.  I don't normally read the zope list.

I have a long running process that will be started by Zope.  This

Zope.

My basic questions are:
	o Can I have an ILU mainloop inside of Zope?  (I really don't
	  care if I have to hack Zope or if I can use an external
	  method.)

	o Should I fork/exec the long running process and give the
	  process a URL that indicates where the data should be
	  written?  (I can use pickles or sql.)

	o How do I tell Zope that new data is avaliable if the process 
	  is external to Zope?

Ok, what's the trick to getting special characters to be converted to
their escape codes (eg. " to &quot;). This is particularly important for
forms in which the user may enter these types of character. 

For instance, if I create a property on a folder that is a string, and if
the string I enter has quotes around it... it doesn't show in the
interface the next time I go to edit the properties. For example, in
MCExam, the 2nd sample question has this as an answer "bar, spam". If I go
to the folder's properties to change it, it doesn't show up. In the source
it looks like: 

<input type="text" name="ans3:string" size="35"
   value=""bar, spam"">

Obviously, if I then save changes, the value is gone altogether.

Is there a way of automatically converting quotes and other special
characters to their escape codes (like the sqlquote method)?

Thanks,

Sorry, your ideas don't work either.

This time I get a NameError for mhost in the following code in
SendMailtag.py.  mhost is never being created.


        if self.mailhost:
            mhost=md[self.mailhost]
        elif self.smtphost:
            mhost=MailBase()
            mhost._init(localHost=gethostname(), smtpHost=self.smtphost,
                        smtpPort=self.port)

        mhost.send(self.section(md.this, md), self.mailto, self.mailfrom,
                   self.subject)

I do not know much about CORBA but you might find it helpful to check the
ZClient library that comes with Zope. You can use ZClient to script Zope
actions. In other words you can have your CORBA proccess running
independently of Zope and whenever there are available data you can call
Zope using ZClient and update whatever you need to.

Grovelling through the source I find something called html_quote in 
lib/python/DocumentTemplate/DT_Util.py, so I tried:

<!--#var nastyvar html_quote-->

Which seems to so the right thing in the generated source. I'm not sure
how to get at the equivalent method call, though.

Does that help?

(p.s. there's url_quote, as well)

I think we're trying to assign a string where a mailhost object is needed.
I'm not sure how to get around this, without an external method. Though
with an external method, it'd be pretty simple:

(warning: untested)

def get_mailhost(self,property_name):
	""" gets the mailhost """

	mailhost_id = getattr(self,property_name)
	return getattr(self,mailhost_id)
	
Or something like this... [shrug]

Both answers are much appreciated. Things start to clear up, but ...
As far as I understand zope it should also be possible to have forms send
data directly to external methods. How do I go abouth to make the argument
list in a python function so that it receives more than one 'form variable'.
1 is simple, but my form consists of 5. I get an error constructing the
python function to take 5 arguments. How is the 5 'variables' sent to the 
method? How do I get hold of the values each store?

Lotsa questions - probly me doing things the wrong way but - I'm learning:)

Yes. This is just what I was looking for.

This leads to a followup question/request for the group.

'manage_addProperty' calls various converters from ZPublisher.Converters
to format the properties values. Shouldn't html_quote be used when
formatting strings and text? This would be trivial to change. Would this
cause some problem I don't realize? If not, I'd like to add this to the
Collector for the next version.

Message-ID: <Pine.WNT.4.04.9903041647000.268-100000@rigoletto.ski.org>

I have a standard_html_header/footer pair which works much like that on
zope.org.

The header inserts a <!--#var sidebar--> in the left column.  The
sidebar DTML method is:

<!--#in expr="objectValues(['Folder'])"-->
<!--#if hidden -->
<!--#else -->
<a href="<!--#var id-->"><!--#var title--></a><p>
<!--#/if -->
<!--#/in -->

(show links to sub-folders which don't have the 'hidden' property set).

The above works fine in the toplevel folder.  In the subfolder, however,
nothing shows up, even though there are two folders which do qualify.

I'd tried originally to have it be a DTML Document and change the expr to
_.objectValues(['Folder']), but that doesn't work at all.

What am I missing?

Check if your DTML properly closes all tags. I had something similar
happening to me in a complicated DTML, when some condition failed to add a
</TABLE> tag. 

BTW you can use
<!--# unless hidden-->
...
<!--# /unless-->

Yes! This was exactly what was causing the error. I added a new 'System
DSN' which then showed up under IIS, and now I've got a shiny new and
perfectly functional Z ODBC Database Connection. 

Much thanks!

PS - Don't know if this info is helpful, but I noticed that (after I set up
a valid System DSN) when my attempt to add a new Z ODBC DB Connection in my
IIS/1.10.2 environ was flawed for whatever reason I would receive the
cryptic 'HTTP Error 400 - Bad Request' from IIS. After some very quick
poking around I noticed that even after selecting a valid dsn, flaws such
as trying to add a connection with an ID already in use, or entering an
invalid connection string would give this 400 error - whereas in my
ZopeHTTPServer/1.9 environ I would receive relevant and helpful error
messages in such situations... Wish I knew more about how to help fix...

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the
MySQL
module to make sure it works. When I do, I get yet another error.

Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: libmysqlclient.so.6: cannot open shared object file: No
such
file or directory

The file does exist, so I am once again stumped.

Thank you for your continued assitance.

Let's assume that it is in /usr/local/mysql/lib.

The easiest way to accomplish what you want is this.

1.    cd /etc
2.    vi ld.so.conf
3.    Goto the end of the file and add a line that says
'/usr/local/mysql/lib'
      replace this with the exact location of you libmysqlient.so.6
4.    save the file
5.    run 'ldconfig'
6.    run 'sync' twice, this just makes sure all changes are written to the
disk.

This adds the mysql lib directory to the lib search path.

Why not use a MailHost Object? On that object you can then set the
appropriate SMTP Host, even from DTML code..

Yes, because you sometimes (most of the time, really), want to have the raw
input from the user. If you then use this raw input in HTML again, only
*then* should you quote out any HTML. Besides, what if I want the data to
be URL quoted? Or SQL quoted?

Just a quick shot: Could it be that the value 'hidden' is aquired from

I did notice today that IIS 4.0 seems to be the cullprit. Whenever Zope
returns a 400 error (like 'sorry, an error occured') IIS mangles that into
the 400 Bad Request error.
This means the traceback is also gone. *grmbl*. Just try and add a
Principia Draft and not specify an ID, and compare this to the message
returned when using ZopeHTTPServer. I think I'll switch to ZServer.

Maybe this should go into the FAQ... I'll cc to ZDP

BTW, I hereby retract the bug I reported to the Zope Collector regarding
ZODBC connections being broken. I forgot to fill in the ID :|. IIS mangles
the returned errormessage.

What is the procedure for retracting bug reports? mail support@digicool.com?

Message-ID: <Pine.LNX.4.04.9903050506001.1539-100000@gaaros.msrc.sunysb.edu>

Zopistas

I have encountered problems mainly associated with ZServer and ZAP:

I am using Zope-1.9.0 and the preconfigured Apache server to run my Zope
site. Last night (a couple of hours ago!) I installed ZServer. It wouldn't
run and I had to add the following to start.py to fix it:

import sys,os
sys.path.insert(0,os.path.join('..','lib','python'))

Later on upon entering the management screens I noticed that the id of the
top level folder dissappeared which caused the paths to my objects to
change. With ZAP (the preconfigured apache) I would visit:
http://www.gaaros.com:8080/Gaaros/ to get to the top level directory but
with ZServer is: http://www.gaaros.com:8080/ which spoils all kind of
links that people have on my site.

Switching back to ZAP I got the following error:

  <FONT SIZE="+2">Temporarily Unavailable</FONT>
  <P>
  The resource you requested is temporarily unavailable - please try again
later.
  </TD>
</TR>
</TABLE>
(102) failure during connect
<!--
No such file or directory
pcgi-wrapper-version 2.0a5
-->
</BODY></HTML>  

Seems like ZServer changed my root id from "Gaaros" to nothing.
I called PickleDictionary on Data.bbb directly from python but I could not
even see the subobjects. BTW can the Zope Data.bbb be accessed directly
from PickleDictionary??

Also trying to shut ZServer from the control-panel results in a core dump.

Ok enough for now, its very late and I cannot think anymore.

If anybody has any clues about the root object id problem please let me
know.

Thanks

Pavlos

No problem. Basically I filter all emails arriving in my personal account
that contain FAQ in the Subject: field. As I am subscribed to all the Zope
lists it doesn't really matter where you send it to.

This is a poor answer (as most here know I don't have the mental
horsepower to provide good responses :^), but...our _intention_ over
time is to have "ZServer" allow objects to be published via PCGI,
FastCGI, HTTP, FTP, and CORBA simultaneously.

Ideally we'd get some kind of Python implementation into the Medusa
handler layer.  Obviously this approach has some serious drawbacks...

Anyway, I realize that I'm not providing much of an answer, so sorry :^(

Right, understood.  We had to spend a lot of time figuring out Gadfly in
order to host it inside Zope.  Thus we labeled it "Demo".

I imagine that it is best for everybody if we take Gadfly out of the
base Zope and make it an external, no-warranty package like the MySQL
support.

This is really weird, it just reminded me of a (rather pathetic) dream I

would read Word files.

My DreamTV must be picking up the wrong channel.

I've been awfully interested in XML in the last few days.  Can you
describe what user-visible benefits PHP delivers due to its integrated
XML parser?

Additionally, we are working on Zope searching for a consulting project
right now.  Actually it is Zope Cataloging.  It's still a
consulting-only option, but plans are that eventually it will go "below
the line".

I *think* I have some good news to report on this, but before I squawk,

There have been a lot of suggestions on this one.  Here's another one: a
command-line program that takes everything out, such as the wget
program.

I'd like to have this as well.  I've been doing a lot of thinking about
this lately.  It is a bit more complicated than expected, though...

This is the main reason I replied.

Having Zope as a free and Open Source(tm) platform is the heart of our
business plan.  A closed Zope would basically mean we start over
completely as a different company.  Thus, closing Zope is roughly
equivalent to closing our company.

With _that_ said, we still need to provide some assurances that we won't
legislate the connection between Zope and DC.  First, we are trying to
keep some arm's length distance between zope.org and Digital Creations.
We hope to formalize the way the community participates in the platform.
We expect to make it lucrative for other businesses to participate.

At the same time, we intend to pursue commercial opportunities atop the
platform for vertical applications.

Ultimately this is the same question put to Netscape regarding Mozilla
during the AOL talks.  The answer is simple: "The genie is out of the
bottle."

Since it is open sourced, Digital Creations must *earn* its stewardship
of Zope.  If we don't we'll become less relevant.

Earning the community's enthusiasm is pretty simple, I think.
Unfortunately we aren't doing a good job right now, though we are trying
damn hard.  But we'll keep trying...

In the meantime, I'm absolutely ecstatic to see folks in the community
step forward over the last month and lead the way.

Yep, the zope.org machine has five virtual hosts.

Previously answered.

Ditto.

We put them in the database.  The 3 Mb Zope binaries are served out of
the database, the PDF files are served out of the database.  This works
so well I don't even think about it any more.

hmmm. That's interesting because it works just like oracle or it
should,unless there are more bugs you haven't passed on to me.  Let me know
what caused the problems.  Basically any non-conformance with the db-api
is a bug.  Please report it to the gadfly-rdbms list.

Yes, this is fine.  BTW, it might be hard for your existing customers to
upgrade to Gadfly 1.0 since I think the db file formats are different
(that's why it was called beta, so I could change things like that).

I remain, Yours Truly,  Aaron Watters

I would suggest, first off, to use 1.10.2.  ZServer is being developed

Yes, there were discussions on this in the list about this problem.
Someone needs to go back, rassle up the discussion and submit it to the
ZDP.  Looks like you found the fix.

Hm.  Is your Zap .pcgi file named Garros or does your RewriteRule look
for Garros and then call PCGI?  If so that is why you need to use Garros
to reach the server.  ZServer can server right out of Zope and doesn't
have this problem.  Your description makes this sould like it is a
production site, I would not suggest running ZServer on a production
machine as it is alpha and still buggy.

This error comes from PCGI.  It can't find your .cgi file so Zope isn't
even being launched.  Did your zap.conf file change (specificly the
RewriteRule)?

You can open a Data.bbb file into a PickleDictionary, but you won't see
anything useful unless you really know what your doing.  The Database
itself is not a Pickle, it is a database of Pickles.  I have attached a
small 5K script that will be released with 1.10.3 which paruses the
database and generates reports.  In the future we are intending it to
translate the entire database into XML for transport. (Note, we do not
intend to use XML as the db format)

I suspect this is because you are using 1.9.0

It's allways worth while! :)  I think the point paul was trying to push
is that we are interesting in publishing our objects over various
transport protocols.  If you want to look in this direction, probably
the best idea would be to write a Medusa handler.  Check out Sam's site
at:

http://www.nightmare.com/medusa

There currently exists an ftp and http medusa handler for Zope, which
you can look at in the latest ZServer alpha release availabe at
zope.org.  I'm not sure is there is a Medusa CORBA handler or not, I
suspect not, but maybe there's some type of CORBA out there written in
Python?

Yes.  ZServer really restores Zope's original intent from the Bobo days:
publishing objects through a variety of protocols.  I think ILU support was
once attempted back in those days.  However, a Bobo app at that time could
only have one publishing mechanism (ie, CGI, PCGI, FastCGI, ILU, etc...).
ZServer allows for multiple publishing mechanisms in the same application,
allowing access to the objects through the web, through FTP, or through any
other protocol developed for ZServer/Medusa.

Subject: [Zope] Documents for web and paper
Message-ID: <012c01be6729$74f6bd40$0201a8c0@hawkeye.bob.oc>

I'm looking for the best way to store and
retrieve documents with these requirements:

SPECS
*Easy storage and retrieval on the web
*Pretty printing on paper
*Easy simple collaboration (no checkout)
*One BASE format for both web and paper
*Base format *could be* edited with
   Word or WP
*Preserve text markup:
   bullets, bolds, underlines,
   tables, graphics, links...etc.
*Search by keyword
*Search by full text


*******
I look forward to comments and
Ideas on implementing this in ZOPE
Perhaps some of this has been solved
already and I don't know it.

EXAMPLE:
Say you have a small book/article
 that is fully contained in a WORD
or WP file.

It has chapters and sections:

Chap1 Plants
      Section1: Trees
      Section2: Flowers
      Section3: Vegetables
      Section4: Fruits
Chap2 Animals
      Section1: Dogs
      Section2: Cats
      Section3: Fish
      Section4: Humans

Ok, as a paper document in the
word processor it is laid out *nice* with
a new page for each chapter, section,
and subheadings for groups of paragraphs in
each section. It prints *nice* and can
even have a table of contents and index.

For the web, the whole book could be
one LONNNG web page.  Ugly and it
doesn't work well.

Ideally on the web each chapter and section
would be navigable with a left hand frame
like table a la http://www.zope.org.  Then
sections can be placed on separate pages
on the right.  This means that the one source
document becomes multiple html
"files" on the web site.

*Tree Navigation
Ok, for tree navigation like
http://localhost:9673/QuickStart
Each Chapter and Section becomes a folder and
the text from each section is contained in the same
named: "dtContent"  as in
...9673/QuickStart/Outline/Applications/External/dtContent

While the tree is nice,  and separate html "files" make the
website better,

*REVISIONS with TWO OUTPUTS

How do you do:
Make revisions to the source document in word/WP
and have it FLOW automatically to html format or
tree format for the web?

*Perhaps* XML could come to the rescue as holy grail
to help solve this problem???  I understand the idea
of mark up but how does it solve the problem of two outputs?

Can you have a template that automatically chops up
the SOURCE into the appropriate folders/files etc and
feeds it to ZOPE?   Can this or another template reformat
for pretty printing including page numbers that are
updated based on the planned printing?

Maybe I need to reconsider how documents are
stored as source, i.e. not Word.  And if not,  what
tool or mechanism would be best?  Maybe the
NATIVE source could flow to Word/WP or
via a template making for pretty printing.

Maybe for simple stuff, the source could be
simple text entered on a webpage or sent
by e-mail with *simple* markup and parsed
automatically?

*KEYWORD SEARCH
Ok, on the web (and Zope), the benefit is it's
searchability:  Do we "hide" keywords in the
source somehow and in addition use Chapter
and Section titles as Keywords?

Search for: "dogs"  gives a result of
Chapter 2 Section 1 in the example as
one entry.  Additional entries might
be lessor cross references such as
a keyword "dog" in the Section 4 humans
as "man's best friend".

*FULL TEXT SEARCH
Ok so we search for the word "Daisy"
and this word is found in the text in
sections: Flowers, Dogs (as a pet name)
and Humans (as a proper name).

The result is then three line entries that
take you to the words.

*Zope IDEAS for this?

I assume that it would be best to store
the documents and source in the ZOPE
database rather than an external datasource.

Nah -- getting rid of the hidden test doesn't change a thing.  Sorry I
confused the issue with that.

I think my problem has to do with my lack of understanding of the
interactions between acquitision, DTML Methods, DTML docs and namespaces.  
I just noticed that the standard html headers and footers are methods.  
That means, if I understand the earlier email, that the default namespace
in them is that of the thing they are contained in.  So, in my case, the
top-level Folder.

Now, in the sub-folder, the standard html headers and footers are acquired
from the toplevel folder.  The standard header does a #var sidebar, which
also lives in the toplevel folder, and that gets included fine.  Within
that sidebar, I'm not sure what the default namespace is -- my fuzzy
understanding makes me think that it should be either:

  a) the / Folder (the 'physical' container for the DTMLMethods)

  b) the sub Folder (the container for the thing which did the
     aqcuisition, namely the index_html DTML Document.

Problem is, neither of these makes sense given what I'm seeing.  If it was
a), I'd expect the 'objectValues()' call to return the same list of the
subfolders of the toplevel folder every time.  If it was b), I'd expect
the thing to work and give me the subfolders of the subfolder.

Let me try to summarize the hierarchy:
  
   /
     - index_html  (#var standard_html_header...#var standard_html_footer)
     - standard_html_header (#var sidebar)
     - standard_html_footer
     - sidebar
     SubFolder1/
     SubFolder2/
        - index_html  (#var standard_html_header...
                       #var standard_html_footer)
        - SubSubFolder1
        - SubSubFolder2       
    
The top sidebar shows SubFolder1 and SubFolder2, the /SubFolder2 sidebar
doesn't show a thing.

PS: Thanks to pavlos for pointing out the #unless tag.

PS: For some reason the title of the root folder is "Zope" in the
    properties tag but doesn't show up in the tree or in the pathlinks.
    Anyone have a suggestion?

Try: <!--#var "sidebar(PARENTS[-1],REQUEST)"-->

This will call the method using the root folders' namespace, thereby
showing all qualifiying subfolders regardless of where the method is
called from. You might have to modify your method to construct absolute
URL's.

Thanks!  What I actually wanted was sidebar(PARENTS[0], REQUEST), but you
pointed me in the direction I needed.  Now I have to understand it, but
that's much easier with working code. 

This also led me to find a bug.  I was wondering why the REQUEST parameter
was needed, so I tried to remove it.  The next time I loaded a page
calling this code, the ZServer process died with the Win32 equivalent of a
segfault.  Is it just me?  I don't dare try it on another Zope server =).

Yeah, I already figured out that the problem was actually in the
OFS/properties.dtml file (I moved over to the zope-dev list, as I realized
this thread really belongs there). In properties.dtml the 'string' type is
listed twice:

  <!--#if "type in ('string', 'int', 'long', 'float', 'date')"-->
  <input type="text" name="<!--#var id-->:<!--#var type-->" size="35"
   value="<!--#var "_[id]"-->">
  <!--#elif "type=='string'"-->
  <input type="text" name="<!--#var id-->:string" size="35"
   value="<!--#var "_[id]" html_quote-->">

'string' needs to be removed from that first list. I'll be submitting this
to the Collector.

I'm new to Zope. I'm very excited about it's potential, but my first
impression is that I will need to master Python in order to use it. I
believe Python is an excellent language, but I do not have the time to
learn it. Several questions about this:

- Can I achieve anything useful in Zope without touching Python? I can
learn DTML, of course.

- if so, what I can and what I cannot do without Python?

- could I, for instance, do something like slashdot.org without Python?

- is there a plan to give Zope features (or ready-made
modules/factories) that would completely eliminate the need to work with
Python (for certain tasks that can be automated or turned into
templates)?

Hi guys:

I'm trying to write a SQL method though, and its giving me an error when I

The query I was using:

Any ideas what I could be doing wrong?

BTW, Zope is great! I've been kinda messing around with it for a while,
also checking out PHP3 and other UNIX-based scripting languages and I've
very impressed.  As soon as I figure out what is causing this I plan to

I found a great description about XML in:
"20 Questions on XML"
http://builder.com/Authoring/Xml20/index.html

On Paul's Zope roadmap: (Jan 18th)
http://www.zope.org/Information/Roadmap

"(2) XML. Zope is a great fit for XML, even better 
with the machinery from Tabula going in. We also 
see XML becoming the basis for other initiatives, 
such as WebDAV and RDF. However, we just can't 
squeeze out the time to dive in deep. Rather, we'd 
love to see more community progress like that 
which popped up this weekend."

I did a search for postings that had "XML" 
in the subject and found
55 messages in ~6 threads between
Jan 8th and Feb 2nd

Other messages have "XML" in the body.

Hopefully we can get some OUTLINE of how ZOPE
and XML can work together.  --- A framework for
further discussions.

You do not need to know a single line of Python to use Zope.  But
learning Python is a pleasure, not a chore.

You can do just about anything with DTML.  In fact, most 'Products'
(read that, 'Zope Extnesions') are mostly DTML.  If your not writing a
Product then you can stay entirely in the domain of DTML.  DTML does use
a small bit of Python in itself, these are called expressions.  For
example, if you had an integer called num you could use:

<!--#var num-->

to 'render' it in your web page.  To get num + 1 you would use:

<!--#var "num + 1"-->

The contents of "" is a python expression.  But it's not a python
program.  If we didn't use Python we'd of had to have come up with some
other language like way of doing this that you'd have had to learn
anyway.

> - if so, what I can and what I cannot do without Python?
> 
Python is used for the following:

To write Products. This is hard core development.

To write External Methods, which are used to hook special or
wierd/pre-existing python functions into Zope.  This is rarely necesary.

> - could I, for instance, do something like slashdot.org

Yes.  There may be a 1% slice of something like slashdot needing a bit
of Python.  But remember, slashdot is a huge application written
entirely in Perl.

Yep.  These are called Zope Classes.  They are still in-house here at
Digital Creations because we are still debugging/figuring them out.  A
Zope Class lets your create your own objects that can be added into Zope
without writing Python code.

More information on my front.. I've been fiddling around a bit trying to
find out what is going wrong..

I'm using ZServer/Zope 1.10.2 with ZMySQLDA that I just downloaded 2 days
ago.

The traceback is as follows:

<!-- Traceback (innermost last):

-->

line 384 of DA.py -- __call__ reads:
query=apply(self.template, (p,), argdata)

I added a bit of debugging code and was able to a take a look at some of
the data being passed around:

argdata was {'sql_delimiter': '\000', 'client': '1', 'pend': '1',
'pstart': '1', 'sql_quote__': }

This is starting to confuse me because simple queries work fine within
Zope, its only the query that I posted in my previous message that seems
to be fowling things up.

I'll keep slagging away until either I figure it out or someone tells me
its not something I've done and that I should submit it to the Collector
:)

Subject: [Zope] DatabaseError: Corrupted data record...
Message-ID: <199903052137.VAA24776@finan.ncl.ac.uk>

Hi all,
Firstly, I'd like to thank everyone for the detailed replies I got to my 'Tough Questions' post.
I'll reply individually to you all and try to answer some of the questions that *I* got asked, but as 'they' say...

"...there is one small problem!" (MPaTHG)

My database has got nuked.

I don't know how it happened, but this is the tail of my serve.errors file

  File "lib/python/OFS/Application.py", line 319, in open_bobobase
    Bobobase=Globals.Bobobase=Globals.PickleDictionary(
  File "lib/python/BoboPOS/PickleDictionary.py", line 159, in __init__
    db=apply(DBType,(),storage_options)
  File "lib/python/BoboPOS/SimpleDB.py", line 221, in __init__
    self.open(file_name,create,revision_time,meta_index,read_only)
  File "lib/python/BoboPOS/SimpleDB.py", line 287, in open
    try: self.index,self.pos=read_index(
  File "lib/python/BoboPOS/SimpleDB.py", line 1365, in read_index
    raise DatabaseError, ('Corrupted data record at %s' % pos)
DatabaseError: Corrupted data record at 1087646

Trying to 'start' the server again just results in the serve.errors file being touched.

As you'll know from my 'Touch Questions' post, I'm a novice in Zope (but I've bought the Lutz 'Programming Python' book, have two more on order and have been reading and rereading the docs all week...so I'm learning fast), but this has me stumped.

I haven't got too far into my Zope 'career' yet, so I won't be devastated if I have to replace the database from scratch (how do you do that by the way?), but I'm sorta worried about the way that all my work seems inaccessible to me now.

any and all help would be ... appreciated.

Okay, now it makes sense.

Is 'client' a reserved variable?

If so, perhaps a warning would be nice if you attempt to use a reserved
variable as an argument to a SQL method.

Argh.. so I got that fixed and now I am getting another traceback when
testing the SQL method!

I can't believe it :)

Here it is:

Subject: [Zope] [DTML] creating variables
Message-ID: <Pine.WNT.4.04.9903051334580.264-100000@rigoletto.ski.org>

I need to detect not only whether a list is empty (that's easy with the
#if tag for example), but also whether all of the elements in the list
have a property. In Python, one could do this with something like:

  empty = 1
  for element in theList:
    if not element.hidden: empty = 0
    print element
  if theList and not empty:
    print "no non-hidden elements"

What's the equivalent DTML?  Can one create a variable in DTML?

Can anyone tell I miss my Python when writing DTML? =)

I didn't try such a thing before. But because the Zope
database is always only appended to (if I'm understanding right),
you might try to truncate the file upto that offset and see
if it is working again? (please keep a backup :-)

Subject: [Zope] Authentication and Zope.cgi
Message-ID: <199903052211.PAA16445@daikon.tuc.noao.edu>

I'm in need of a bit of clarification about how Zope starts up and when
it decides to do its authentication and why.

I'm running 1.10.2, solaris 2.6, apache, pcgi, netscape 4.07.  When I request
mymachine/Zope/manage   I do indeed get the normal management screen.
I haven't been asked in some time for a password, which suprises me;
the 'access' file exists and (but?) hasn't changed since installation.

I'd really like the root folder to say something other than Zope, so
I added to Apache a second rewrite rule that substitues 'mpg' for Zope
in the two places (restarted Apache), and copied Zope.cgi in cgi-bin
to mpg.cgi .  These two cgi files are identical so they point to the
same /var directory.

If I try   mymachine/mpg/manage  ,  I get an authorization failed box,
and upon clicking 'retry', I get the usual authentication box with
the correct 'access' user entered.  I type in the correct password and
the system fails again ("You are not authorized to use this system.
Username and password are not correct").

So, I'm very curious as to what's going on ... and I wouldn't mind
learning how to change the top of the root name as well.

OTH if you have most of your code written in DTML it is so easy

What version of Zope are you using? What OS?  Were you using NFS? MySQL?

Please send *in private mail* me a gzipped tar file (or Zip file) 
containing the Data.* files from your var directory.

Any other thoughts you might have regarding events leading up to this
would be helpful.

Good point.  I should have mentioned that as a quick

But please send me the file before you truncate it. :)

Hmm. I want to create a variable whose value is given by another value.
Doing:

<!--#with "_.namespace(foo=<!--#var id-->)"-->
<!--#var foo-->
<!--#/with-->

doesn't make it through the parser.  

I've tried adding various quotes to no effect.

I think I'm going to work on understanding ExternalMethods -- this syntax
is not made for me. =)

Why does my ZMySQLDA Z SQL Method die with a KeyError: unhandled message?

Well, I was looking at the code for the MySQLmodule and it appears that it
has problems handling some fields.

This appears to be a limitation of the MySQLmodule.  It currently does not
handle the LONGLONG datatype longer timestamps use.

At least I assume its the LONGLONG that is messing it up.  I haven't
looked into that much detail to be honest.  

I'm not quite sure if this is something that should be included in the
FAQ, or considered a known bug, or submitted to the Collector?

Thanks,

This surprises me, since as far as I can see, one is always asked for password
accessing /Zope/manage. Does netscape 4.07 automatically go through authenticate
procedure?

There are at least two possibility.
1) Misconfigured rewrite rule.
2) mpg.cgi is not altered suitably.
(oh, 1+2 gives the 3rd possibility).

I was in a similar situation a few days ago. Now one of apache virtual host on my
linux box has 1) ordinary apache site tree, 2) experimental(read 'for play') Zope
site under  hostname/Zope/ (through Zope.cgi)
3) public Zope site under hostname/public/ (through public.cgi)
If this is similar enough to what you want achieve and you are desperate enough,
just mail me your rewrite rule and Zope.cgi & mpg.cgi with sensitive parts
altered suitably. But be aware that I am new to rewrite rules and pcgi
world(hence if you are desperate enough).

This is easy. Just edit BOBO_REALM (NAME?) in your *.cgi file.

LEE Kwan Soo.

ps.  my Zope's have their own var/Data.bbb but you want your Zope to point to the
same var/Data.bbb. Oh this seems far beyond the capacity of mortal being. If you
really want need this setting, I guess, the easist way to achieve it is getting
Zopal blessings from DC(i.e. make a consulting contract with DC).

I'm guessing that the parsing of the tokens picks up on underscore

Ouch!, what we do is save the word docs as RTF. A free program (written in
Omnimark) called RTF2XML then trundles through it and creates well-formed
and valid XML. I then pass it through another Omnimark program that I wrote
that turns it into XML that is more suited to what we want.


>I've been awfully interested in XML in the last few days.  Can you

>

Background:...
PHP is a (non OO) server-level scripting language, usually delivered as an
Apache module, that has it's roots in C, but with some of the arcane bits
removed. It's database integration is very good. The authors have recently
built the (almost XML-industry standard) parser Expat into it.
...

From my point of view, having the XML parser in PHP meant that (a) I didn't
need to call Perl CGIs (with all that overhead), (b) I'd understand the code
a bit (I *cannot* do Perl!), (c) there might be a performance boost from
having the parser in the Apache Module and (d) I'd be able to map XML
elements such as <topic> ... </topic> into HTML <div> ... </div> tags or RTF
control codes (all of which would be read from a user-defined database) -
thus leading to the 'Holy Grail' (ouch!) of being able to render the
documents into whatever form the end-user wanted. As well as that, using XML
means that I can select all <topic> .. </topic> tags that match a certain
criteria (eg, all first-year study guides that mention cell biology) from
*all* our study guides and create a 'composite' document that would be
passed through the XML 'converter' to get custom HTML and RTF docs.

Of course, once I 'got into' XML I found out that just having the Expat
parser around didn't necessarily mean I was going to get all that for
free...ie how 'do' you 'search' an XML document to get those matched <topic>
tags (and possibly their children). Enter XQL and it's friends, DOM and XSL.

XQL (Perl module based on a W3C recommendation) works, but it's slow. 

In short, I was at an impasse. The level of work needed to incorporate XQL
into PHP (as a CGI) or (gulp) rewriting it as PHP was just too much.

I installed the XML-Config product for Zope and my appetite was whetted. I
read about the XML-sig and downloaded the XML-0.5 toolkit from python.org. I
tried one or two examples out ... and my jaw literally fell open. By the
time I'd looked in the 'dom' directory I was almost gibbering. This was
something I felt I might be able to understand (and definitely use).

Ooops...I'll shut up as I'm waay of topic.

No, but I've spent the last week muttering 'ok, I can use UserDB to
authenticate against our StaffDB and allow per-user access to the file
upload area', 'yeah, should be able to rewrite my PHP Multi-Choice Question
engine in this DTML gubbins', 'ok, I'll pull in the Perl script that does

Simply this: 
Zope seems to do just about everything I need (which is basically to provide
a *framework* for the Electronic Curriculum - others will fill in *and
manage* the content). I can then concentrate on providing features that
people need and 'rolling them out' to the users of the systems, confident
that they will integrate into the whole system. 

I think it's a paradigm-shifty thing more than anything else. Everyone in
our group *knows* that an .htaccess file allows access to the files in that
directory. They all have at least a basic grasp of CGI programming and all
recognize the mapping between files in a unix file structure and their
representations as web pages. People using Zope will have to break that
habit of logging in to change a file ('cos it ain't there!).

(for the time being, I've desubscribed from the PHP-lists to give me more
room to think!...)

Message-ID: <3.0.6.32.19990306180733.009318b0@hito.eccosys.com>

I think there must be an easy way around a little trouble I'm having, but
it's had me stumped for a few days and I can't find any mention in the
list/docs.

From a dhtml method I want to access a subfolder's sql methods, which is
easy enough using <!--#with SUBFOLDER--> <!--#/with-->. The problem is,
because of the amount of methods involved and in order to keep things
flexible I want to add the <!--#with--> to a standard_header, and the
<!--#/with--> to a standard_footer. Of course, Zope nixes this. So I was
hoping there was an end-run around this dilemna - some other way to give
access to subfolders. 

I've tried including the opening and closing WITH's in the same document
surrounded by IF's with no luck, and have been wondering if there's a way
to set a folder property to accomplish this...

You cannot nest DTML but you can use _[] to access the namespace. For
instance you could do:
<!--#with "_.namespace(foo=_['id'])"-->

I too miss Python when working in DTML.  But in this case, I think that the
following will help:

  <!--#call "REQUEST.set( 'foo', id )-->

Subject: [Zope] Creating Zope a zope application
Message-ID: <19990307130236.A532@RaVER.duck.org>

Hi!

I'm reading 'A technical introduction to object publishing with Zope'.

The doc says 'Creating a Zope application is simply a matter of creating a
regular Python module containing the objects to be published, and placing
this module along with some Zope-provided support files in the appropriate
place on a web server'

The doc continues to say that the zope documentation covers this prosess,
but I'm not able to find it. So my question is - what are those
zope-provided support files, and where am I supposed to place those file
along with the python module that I've created?

Hi,
I've read on the zope-dev list that Zope is not multi-threaded.

Does this have any ominous implications for server performance? I believe it
means problems for people writing products, but does it give problems for
folk using Zope in an 'install products and use them' scenario?

many thanks for any thoughts,

We can discuss this now, but in a short while it won't really matter.
Zope as we know it now is not 'multi-threaded'.  The real issue
concerning Zope is one of concurrency, since the 'threading' of requests
is ussualy created by the web server (Apache using multi-processes or
Medusa (ZServer's) use of select(), neither of which use actual
'threads').  There are two areas that we are working on to make zope
concurrent.

The Database:
	There is a new version of BoboPOS, called BoboPOS3.  It is
currently alpha.  BoboPOS3 supports concurrent processes opening,
reading and writing the Object Database.

'Concurrifying' Zope:
	Concurrent programs have to be careful about some issues.  In
particular, the use of global data.  These can sneak in on you in wierd
ways.  For example, in the regex python module (yes, regex has been
depreciated for re, but for now regex is faster) certain uses of
compiled reg expressions don't work when two 'threads' enter the same
expression.  Also, there is an issue about passing mutable objects as
default arguments to methods.  To be truely thread safe, default
arguements need to be immutable, or mutable arguments can only be used
in immutable ways.

These are, as you said, developer issues.  Product developers have to be
careful not to block Zope for long periods of time.  People in the
'install and use them' scenario should not use these types of Products
unless they are sure the block times are low, and product developers
should be very, very careful about moving their software out into the
world if the product blocks.  It should be made clear to the user that
this software could stop up the whole works.

Why is won't matter soon is because we are working on making Zope fully
concurrent.

Message-ID: <l03130300b309086b41cf@[206.40.158.77]>

Advice needed, opinions wanted.

I have a situation where there is a group of users with both a private
space and a public space. The users homepage is considered private with the
public space where all anonymous viewable docs are held. I have two
thoughts on how to do this, Zope is capable of either method, I'm curious
which method everyone else thinks best, and why.

First method;
community folder (contents public viewable by permission)
     user_folder (contents not public viewable by permission)
	users manage page (not public viewable by aquisition)
	users public folder (public viewable by permission)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by aquisition)

Second method;
community folder (contents public viewable by permission)
     user_folder (contents public viewable by aquisition)
	users manage page (not public viewable by permission)
	users public folder (public viewable by aquisition)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by permission)

Both have advantages and disadvantages, either way I end up with on - off,
off - on, in the permissions hirearchy. Anyone have a good argument for
either method?

Subject: [Zope] Why doesn't this loop over files?
Message-ID: <v04104422b3094ee5414d@[128.240.198.13]>

Hi,
I've d/led the ZopeDemos folder, installed it and started learning 
more about Zope, but there's something happening that I'm not sure 
about.

The 'looping' example doesn't seem to iterate correctly over new 
additions to the folder. The DTML is here:

<!--#in "['Document','Folder']"-->
<!--#if "objectValues(_['sequence-item'])"-->
   <H3>Objects of type <!--#var sequence-item--></H3>
   <TABLE BORDER=1>
   <TH>Id</TH><TH>Title</TH>
   <!--#with subFolder-->
      <!--#in "objectValues(_['sequence-item'])"-->
        <TR><TD><!--#var id--></TD>
        <TD><!--#var title--></TD></TR>
      <!--#/in-->
   <!--#/with-->
   </TABLE>
<!--#/if-->
<!--#/in-->

If I create a new DTML method or document in the folder 'subFolder', 
it isn't recognised. I've even copy/pasted the documents that do work 
into the subFolder with no joy. Curiously, new folders *are* 
recognised.

My Question is: What's preventing Zope from reading *all* the 
Documents in the subFolder?

This would be the core of my first real application in Zope (a 
resource upload/download facility for staff here) so any advice would 
be appreciated.

thanks
tone.

Definitely. We have dozens and dozens (eventually hundreds) of files 
(QT movies, PowerPoints, Word Docs and the like - the mean size is 
about 600k-1Meg, but we have quite a few monsters at 6-7 Megs).

This would be excellent news for us.

Does this ensure that MIME types are kept with the document, so that

Ad-hoc Zope FAQ version 0.1.1

    This FAQ is a FAQ in progress. It is uncompletely unstructured;

    maintain a particular FAQ section, please mail to the ZDP
    list. Thank you in advance!

Note on the use of StructuredText:

    See the (currently) first FAQ entry for information on how to
    render this FAQ into HTML using Zope. For more information on
    StructuredText see::

        http://www.zope.org/Documentation/Reference/StructuredText

    but this link is currently not completely up to date; see the
    comments in 'lib\python\StructuredText\StructuredText.py' for the
    current documentation.

* How do I render the Structured Text FAQ into HTML cleanly? (in Zope)

    When including Structured Text (STX) from a DTML Method into
    another Document with the 'fmt="structured-text"' attribute, it
    will be quoted twice. This is because the '__str__' method of the
    'DocumentTemplate.HTML' class automatically quotes its HTML when
    called.

    You can work around this by calling the STX document's
    'read_raw()' method to get the unquoted version.

    This way we can use unquoted Structured Text examples in our FAQ::

        <!--#var "FAQ_Document_stx.read_raw()" fmt="structured-text"-->

    Note that if the STX comes from a property the 'read_raw()'
    workaround is not needed.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

    Another possibly is to use '_.getitem()', like this::
   
        _.getitem('sequence-item')

    The difference is that the first renders 'sequence-item' through
    DTML, whereas 'getitem()' does not; it returns the raw value of
    'sequence-item'.

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their
names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like 'REQUEST.form', 'REQUEST.cookies' and even
    'REQUEST' itself. Just call the 'items()' method of the
    dictionary, and the #in tag will provide a 'sequence-key' and
    'sequence-item' variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
          <!--#var sequence-key-->:<!--#var sequence-item--><BR>
        <!--#/in-->

    Use 'REQUEST.cookies.items()' for all your cookies, and
    'REQUEST.items()' for all 'REQUEST' variables, including CGI
    Environment variables.
    
    If you don't mind the format, you could use '<PRE><!--#var
    REQUEST--></PRE>' as a shortcut.

* What is a Principia Draft?

    A Principia Draft is a special copy of any Zope object that is
    invisible to visitors of your site. You can make changes to this
    copy, and grant access to outsiders to view your changes (or work
    along with you). When all changes are done, you can approve all
    the changes, or discard them. Approving will make the changes
    permanent and visible to your audience. However, currently Drafts
    can appear to be broken.

    To add a draft, choose Principia Draft from the popup menu and
    click 'Add'. Next, you will have to supply an ID for the Draft,
    and specify on what base object you are going to work. Clicking
    'Add' in this screen will create the Draft for you. Next, you will
    have to specify who will have access to the Draft.

    Here the problem starts, because of the way Drafts are
    managed. First, a Draft doesn't acquire any users from its parent,
    so you will have to add anyone who has to have access explicitly,
    even if they have already been access to a parent Folder. But the
    biggest problem is that you can't reach the UserFolder and
    Approval screens via the management screens. This will make a
    Draft a bit harder to use, but it still is workable.

    This second problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately.  Principia Drafts made use
    of the call to 'title_and_id' to insert links to its UserFolder
    and Approval management screens. As this now doesn't happen
    anymore, you will have to type in the URLs to the screens
    yourself.

    You can reach the screens calling the Draft object's
    'users__draft__.manage_main' and 'manage_approve__draft__'
    methods. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

    So, the next step is typing in the URL to the Draft's UserFolder
    management screen, and adding all users that should have access to
    the Draft. These users can now edit and view all changes made to
    this Draft.

    When done, you go to the 'manage_approve__draft__' management
    screen, and approve, or discard the changes.

* How does my Folder Product load default documents?

    Create a list of tuples containing filenames (without '.dtml') and
    title pairs::

        self.defaultDocs = [
            ('index', 'NotMail'),
            ('address', 'Address Book'),
            ('attach', 'Attach a File'),
            ('composer', 'Compose a Message'),
            ('contact', 'Contact Developers'),
            ('search', 'Search Your Mailboxes'),
            ('results', 'Your Search Results'),
            ('folder', 'Mailbox'),
            ('message', 'Message'),
            ('help', 'Help'),
            ('lookup', 'Lookup Users'),
            ('standard_footer', 'Standard HTML Footer'),
            ('standard_header', 'Standard HTML Header'),
            ('noto', 'Message must have at least one recipient.'),
            ('reminders', 'Your Reminders'),
            ('save', 'Save Message'),
            ('logout', 'You have been logged out'),
            ('GPL', 'The GNU General Public License'),
            ('sentmail', 'Mail was sent')]

        # Then iterate over them and create each one

        for id,title in self.defaultDocs:
            try:
                self.defaultDocFile(id, title, id)
            except:
                pass

        # defaultDocFile is a handy little function:

        def defaultDocFile(self, id, title, file):
            f=open('%s/Products/NotMail/%s.dtml'
                   % (SOFTWARE_HOME, file))
            file=f.read()
            f.close()
            self.manage_addDocument(id, title, file)

    When you are debugging your DTML, it's a pain to keep deleting and
    creating new instances of your object in order to load the new
    dtml files off of the disk. This function comes in handy::

        def refresh_docs(self, REQUEST):
            """ refresh documents from disk (for debug purposes) """
            
            for id,title in self.defaultDocs:
                try:
                    self._delObject(id)
                except:
                    pass
                try:
                    self.defaultDocFile(id, title, id)
                except:
                    pass
            return self.manage_main(self, REQUEST)

    Then, assuming your object has an attribute 'debug' you can define
    some DTML like so in your manage_main screen::

        <!--#if debug-->
        <p><a href="refresh_docs">Refresh Documents from disk</a></p>
        <!--#/if debug-->

* How do I add management tabs to my folder sub-class?
   
   If you subclass 'OFS.Folder.Folder' to build a folderish object,
   you may want to keep around the old Folder management tabs, but add
   some of your own as well. This can be done by mucking with the
   Folder class 'manage_options' attribute. One problem is that you
   might want your own custom 'manage_main' but the FolderClass uses
   'manage_main' for displaying the contents of the folder. Here is
   what I did for my EMarket product.
   
   By examining Folder's manage_options::
   
       for option in Folder.manage_options:        
           print option 

   We get the following output::

       {'label': 'Contents', 'target': 'manage_main', 'action':
'manage_main'}
       {'label': 'Properties', 'target': 'manage_main', 'action':
'manage_propertiesForm'}
       {'label': 'Import/Export', 'target': 'manage_main', 'action':
'manage_importExportForm'}
       {'label': 'Security', 'target': 'manage_main', 'action':
'manage_access'}
       {'label': 'Undo', 'target': 'manage_main', 'action':
'manage_UndoForm'}
       {'label': 'Find', 'target': 'manage_main', 'action':
'manage_findFrame'}
   
   Notice that the "Contents" tab calls Folder's manage_main attribute.
Just
   rename that in your sub-class with something like::
   
       manage_contents=OFS.Folder.Folder.manage_main
   
   and assign that to a different tab. Here is the beginning of the
MarketItem
   class from the EMarket product::
   
       class MarketItem(OFS.Folder.Folder):
           """A MarketItem """
   
           # Specify a name for the item type:
           meta_type='MarketItem'
   
           # Specify a relative URL for the icon used to display icons:
           icon='misc_/EMarket/marketItem'
           
           # rename Folder's manage_main to manage_contents
           manage_contents=OFS.Folder.Folder.manage_main
  
           manage_main=HTMLFile('marketItemEdit', globals())
           manage_image=HTMLFile('marketItemImage', globals())
   
           # Specify definitions for tabs:
           manage_options=[
               {'label':'Attributes', 'action':'manage_main'},
               {'label':'ImageUpload','action':'manage_image'},
               {'label':'View',       'action':''},
               ]
   
           # add in the options from the Folder class.... change
           # the 'action' for Contents to 'manage_contents' 
           for item in OFS.Folder.Folder.manage_options:
               if item['label'] == 'Contents':
                   # be sure to use a *copy*
                   manage_options.append(item.copy())
                   manage_options[-1]['action'] = 'manage_contents'
               else:
                   manage_options.append(item)

Message-ID: <14051.53317.19816.135841@cuckoo.EMBL-Heidelberg.DE>

Hi Zopists,


using StructuredText 
 ($Id: StructuredText.py,v 1.11 1999/02/08 18:13:12 klm Exp $)
for content generation, I find that I can't include tilde (~) characters in
hyperlinks, i.e. a  string like 

	"brabbel":http://www.embl-heidelberg.de/~ehrlich.

is not mapped to 
	
	<p><a href="http://www.embl-heidelberg.de/~ehrlich">brabbel</a>.</p>

but output as literal 

	<p>"brabbel":http://www.embl-heidelberg.de/~ehrlich</p>.
				
I tried to fix StructuredText,StructuredText.__init__ by inserting '~' into
the gsub statements. No success whatsoever...

As I couldn't find this entry neither in the Collector nor in the archive,
I wonder whether somebody has a patch sitting somewhere?

Cheers,
	Lutz

I just ran into this error. When I did a SELECT * on joined tables it would
give the error but if I named the fields I needed it worked. I played with
it a little and got the error again when I named a field that ended in _num
in the SELECT. I have four such INT fields that I don't need, they are used
by the JOIN, and have _n counterparts in the JOINed tables (see SQL below).
As you can see my SELECT list is long and it would have been nice to just
use a * since I need almost all the fields.

Everything works fine in MySQL client but from Zope I can produce that error.

Maybe there is some conflict with the *_num names. What are your field names?

I was able to find a work around.  The problem was the handling of
the TIMESTAMP datatype by the MySQLmodule.  It doesn't know how to handle
a long timestamp unfortunately, so you'll want to retrieve it as a UNIX
timestamp or as a formatted date using one of MySQL's many date functions.

The other thing is that I doubt it handles double long integers since
AFAIK Python doesn't handle these without an extension module.

If your query is returning any of these you'll most likely get this
response from Zope...

   It sure does:

    Spiffy, eh?  I'm pretty sure it's arbritrary-precision, which means you can
make numbers as large as you have memory for.  Or is this not what you
mean?

Hey, I'm glad you proved me wrong :)

It looks like there is a limitation in the MySQLmodule when handling
MySQL's LONGLONG datatypes that could probably be corrected.

I may take a look at this later, but I am thinking I may just store UNIX
timestamps in my database since this is more portable across databases
anyways.

But anyway, this may be a FAQ item as I'm sure other people may run into
it.

Hi All,

I fetched FAQ tool from "http://www.zope.org/WebReview/" but the 
archive contain only :

* __init__.py

*version.txt

*Product.dat


No, FAQ.py file. Strange no. Thus, this is maybe why I cant view 
Faq in the list of objet in Zope!!

Message-ID: <v04003a10b309c53d7c44@[192.168.1.190]>

Here is a strange one -- I am getting an L on the end of integer numbers
from MySQL. (They are INT not BIGINT!) It didn't happen in 1.9, and it
doesn't happen with methods that I created in 1.9 and moved to 1.10.2 (I
think).

In <!--#var--> I have to use fmt='%d' to get rid of it.

I also had a problem when I tried to use one in a redirect:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(num))"-->
produces:
http://server/dir/file_html?num=53L
which causes an error.

I got around that by adding an int function:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(_.int(num)))"-->


Has anybody else experienced this problem? Having to add all this extra
code is driving me crazy!

While this may seem strange, this is in fact the normal contents of a
Product distribution file for a "levered product". When you build a product
through the web inside the control panel, these are the normal files Zope
creates inside the product distribution.

>Thus, this is maybe why I cant view 
>Faq in the list of objet in Zope!!

Unfortunately this is not the case. The reason you can't use the FAQ is
that there is a bug in Zope which keeps some people from being able to use
levered distributions. As discussed on the list, it appears to be related
to zlib compression.

We are aware of the problem and are working to solve it.

Thanks for your patience.

-Amos

P.S. If you're curious about a bug, you can try searching the Collector.

http://www.zope.org/Collector

In this case a search under "lever" or "faq" would turn up the existing bug
report for this problem.

When I try to install binary distribution of zope (on Linux), I run the

bash: ./python: No such file or firectory

even though python binary is there, with correct rights.
Does it mean that the binary lacks some libraries? If so, can I find

No real issues, just d/l the source release and try compiling Zope.  I'd
recommend having Python 1.5.1.  To build the source release to use the
built in simple web server, try:

'/usr/local/bin/python1.5.1 wo_pcgi.py'

to use with Apache (Note, d/l Zap and look at it's .conf file)

'/usr/local/bin/python1.5.1 w_pcgi.py'

Change the command line to reflect your python binary.

Check out, I think, INSTALL.txt in the doc directory.  All the C is
ANSI, and python is python (grin) so you shouldn't have a problem.

Hi Guys:

I think I've nailed the problem that was keeping people from using the FAQ
Tool and levered products in general under windows.

I'd love some confirmation that this does or does not solve people's problems.

The fix is to open the product.dat file in 'rb' mode. To do this, change
line 420 of lib/python/App/Product.py to:

        f=CompressedInputFile(open(home+'/product.dat','rb'),name+' shshsh')

Again, let me know if this doesn't work for you.

-Amos

P.S. Here's a little FAQ to tide you over until you're happily building
your own ;-)

Q. What's the FAQ Tool any way?
A.  Find out for yourself at: http://www.zope.org/WebReview/

Q. What's a levered product?
A. A Product created through the web by building it inside the Control
Panel. See the Zope Manager's Guide for more information.

This fix works for me (lline 407 in my Product.py) 

HOWEVER ... you must delete the FAQ product from the control panel, 
then restart ZServer for this fix to take effect. Apparently the old FAQ in 
bobo inhibits re-reading of the product.dat file.

There's a bug in the code, something I noticed when I was playing 
with the examples too. this is the fixed version:

001 <!--#in "['Document','Folder']"-->
002 <!--#with subFolder-->
003 <!--#if "objectValues(_['sequence-item'])"-->
004    <H3>Objects of type <!--#var sequence-item--></H3>
005   <TABLE BORDER=1>
006   <TH>Id</TH><TH>Title</TH>
007      <!--#in "objectValues(_['sequence-item'])"-->
008        <TR><TD><!--#var id--></TD>
009        <TD><!--#var title--></TD></TR>
010      <!--#/in-->
011   </TABLE>
012 <!--#/if-->
013 <!--#/with-->
014 <!--#/in-->

About the bug and the fix:
the bug was due to the statement <!--#if
"objectValues(_['sequence-item'])"-->
looping over the current folder, not the subFolder which it should be.
By moving the "with" statement to enclose it (see line 002), the
statement <!--#if "objectValues(... now loops over the objects inside
the folder named "subFolder".

I don't know who is maintaining the ZopeDemos product (or if it's
being maintained at all), 
but I hope he/she takes note of this and posts an update. 

Hope this helps.

Butch Landingin
butchland@yahoo.com

PS. I'm playing around with the Confera product (making it more
slashdot-like) but I know it's
not "officially supported" by Zope/DC -- so who's maintaining it? I
have some detailed questions about the code (but I don't know if it's
off-topic for Zope/Zope-dev).

Zopistas

The new version of the FAQ has been uploaded at:
http://www.gaaros.com:9673/FAQ

The format has been changed after Martijn Pieters suggestions. It now
supports structured-text as the default format. Actually it was pretty
easy to upload Martijn Faassen's FAQ.

The e-mail uploading option has been dropped. If you want to submit a
FAQ entry you can do it over the web. Also the XML DTD has been changed
slightly. A typical entry would be:

<entry>
<section>DTML Scripting</section>
<question>How to you become a hermit?</question>
<author>Pavlos</author>
<email>pavlos@gaaros.com</email>
<answer>
Simple:
	
  - Install Python

  - Install Zope
</answer>
</entry>

Only the section and question fields are required. Everything else is
optional. You can view the DTD on the site. Suggestions will be
appreciated.

VS.

where column_name = <!--#var name-->

Is the only advantage of using the first (sqltest) the type checking? I

Butch,
Thanks for the reply - but this doesn't work completely either. I can 
add folders and delete them and the changes made show up in the 
listing, but adding documents (both documents and methods) has no 
effect. If I delete the *original* documents created by the 
installation, they show up as being gone, but even a copy-paste of 
the original documents doesn't get any new documents/methods etc. to 
show up.

Am I doing a dumb newbie thing here? (I *do* have a folder called 
'subFolder' btw).

many thanks
tone

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <19990309084120.83ca0fd9.in@mediamail.telinet.com>

Hi all,

I have been using python for years, and zope for a few months now (lovely),
ZServer for weeks, but Windows NT? Not long enough to understand the
differences between services and ordinary process (give me a break, I am
heavily from a Un*x background) :-).

I know when I installed the binary version of Zope on the windows machine
here it gave me a service in the services list which I can activate on
startup. However, I am betting that this runs the ZopeHTTPServer, not the
ZServer which I got as a separate download. I have everything working just
lovely with the ZServer now, but it needs to be run as an NT service (and
respond to start and stop signals, etc) at which point I freely admit my
own inadequacies in this area.

Now my question. How can I do what I need to do. Is it simply a case of
redirecting a python 'shell' file used by the service to the start.py in
the ZServer module, or is there more to it? If it is this simple, which
python 'shell' file do I use? If it is not this simple, can someone send me
basic instructions on how to do it (why is NT like this - give me an
rc.local file any day - I know where I stand with that stuff).

Thanks in advance.

Dick

Zope-dev is the place to ask specific questions about Zope's API and
Zope Product Authoring.  Go ahead and ask your questions, the unsuported
just means we can't make any guarantees or commit company resources to
it, but if your question happens to use Confera as it's basis all the
better.  Someone out there might have the answer.

Hi All,

The DTML Example folder has been updated. I've incorporated the fix below,
but the reason that new documents were not showing up is that the page was
looking for the wrong 'meta_type' for objects in the subfolder. Up till the
last release, documents had a meta_type attribute of 'Document', but now
documents either have 'DTML Document' or 'DTML Method' as their meta_type.

Tony's problem was that Zope was correctly respecting the meta_type of the
'old' Document objects included with the demo, but any new documents added
afresh were being created with the 'DTML Document' or 'DTML Method'
meta-types, which were falling through the objectValues 'sieve'.

Here's the new version...

Cheers,

Andy.

I haven't played with it too much but I think that Zope handles undefined
variables properly if you do the sqltest.

ie.

where <!--#sqltest name column=column_name type=column_type-->
and <!--#sqltest name2 column=column_name2 type=column_type-->

will work if name2 is not defined.

It also handles the quoting and SQL syntax (such as doubling single quotes).

My guess is that you created your original database in Zope-1.9 and then
moved everything into Zope-1.10. If that is the case then you need to
replace
<!--# in "objectValues(['Document'])"--> with
<!--# in "objectValues(['Document','DTML Document','DTML Method'])"-->
or something to that effect.

Not quite.  ZopeHTTPServer is a console app just like ZServer.  The
service is a PCGI-like thing that runs Zope as a service, listening for
named pipe connections from something that is run as a CGI by the web
server.

ZServer is still at alpha 2 so it's premature to focus on things like
how it is packaged.  I *think* we have all the issues figured out and
the next release, perhaps this month, will be a beta1.  Until we get
into beta, we'll have to hope that someone in the community packages it
up as a service.

One issue off the top of my head is integration with the NT Event Log.

Absolutely...  we ran into some situations where the SQL was so dynamic
potential security problems arose.  sqltest and sqlvar are designed to
reduce that exposure.

Additionally, we've found a very common rhythm where a search UI might
expose all of a large percentage of the available data elements in the
RDBMS.  Using sqltest lets the user not specify one or more parameters
without a lot of messy <!--#if --><!--#/if --> stuff in the SQL Method.

I'll correct myself here. I was thinking of the <!--#sqlgroup ...--> tag. I
don't know what <!--#sqltest ...--> does that <!--#sqlvar name--> or
<!--#var name fmt=sql--> won't do...

I meant to bring this up in my earlier post -- this tag too, is used to
simplify what could be a terribly complicated SQL Method given an
indeterminate number and list of search criteria.

With this tag you can permit an arbitrary arguments to be supplied
connected with your predetermined ANDs and ORs

This one tag has, in the past, reduced may SQL Methods into one --
natural maintenance savings.

A _very very_ nice feature of #sqltest is the 'multiple' feature.  For
example:

SELECT * FROM inbox
WHERE <!--#sqltest doc_status type=string multiple-->

If doc_status is passed in as a single value, like "foo", the SQL statement
will be rendered as::

SELECT * FROM inbox
WHERE doc_status='foo'

BUT!!! (this is where it gets good), if doc_status is passed in as a
list/sequence, like ["foo", "bar", "drop", "ship"], it will be rendered
as::

SELECT * FROM inbox
WHERE doc_status in ('foo','bar,'drop','ship')

This is an _extremely_ handy feature of #sqltest.  Prior to #sqltest, doing
the above might be like:

SELECT * FROM inbox
WHERE doc_status in (
 <!--#in doc_status-->
 '<!--#var sequence-item fmt=sql-->'
 <!--#else sequence-end-->,<!--#/else-->
 <!--#/in-->)

(#else used to be used where #unless is used today).  The above code also
always required doc_status to be passed in as a sequence.  #sqltest is
smart enough (I believe - i've never been bitten by this) to detect the
difference between strings and lists.

I've used #sqltest with multiple many times with Acquisition where a folder
property would define part of a SQL statement.  That property in some cases
would be a single value, in other places it would be a tokens or lines
property.

So, in otherwords, you get the type checking, the multiple, the optional,
etc... with #sqltest that you don't get otherwise.  About the only problem
is that #sqltest currently doesn't do not-equals or "not in (...)".

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?

btw: Zope looks really good to me (when I can get over these glitches).

I found that this problem came up when I used MEDIUMINT in MySQL. I changed
my database to INT and it worked fine.

I bet your using a DTML Document.  Try using a DTML Method.  The reason
why the tree tag renders nothing for the DTML Document is because DTML
Documents are not containers of other objects, they are objects to hold
DTML content.  DTML Methods are (and this is the suble thing) *methods*
of the Folder object that contains them.  They are not 'objects' in the
same sense of the term used for DTML Documents (I can hear Jim saying
now "*everything's* an object").  Because Folder objects *are*
containers, the #tree tag used in a Folder's DTML Method will render the
contents of that Folder.  Hadar's example is a little outdated, it is
based on 1.9, in which DTML Documents didn't exist, and all Documents
were DTML methods.

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <006501be6a52$b0bbe900$fa01a8c0@rogue>

I currently have ZServer running as a service on two machines using the
srvany.exe tool from the NT resource kit or from MSDN.  Essentially srvany
is the actual service and then you tell it via registry settings what other
program you want to run.  It works good enough for me for the time being.

The only problem is that the service stop message does a hard kill on the
ZServer process so any last second updates to the Zope DB might be
fragmented if it wasn't finished writing, but with the way the DB works at
least the DB will still be usable.

I am out of the office right now so I can't provide step by step
instructions right now.  There is a .doc file that comes with srvany.exe
that I followed.  I specified that Python was the executeable to be run by
srvany, the ZServer directory is to be the CWD, and that the command-line
should be start.py.  Worked first try.

Of course the right thing to do would be to integrate native service
capabilities into ZServer itself via the win32api packages.  That way
ZServer could shhutdown gracefully and could send meaningful things to the
event log.  But srvany is good enough for alpha level, non-production
servers.  And I havn't had any problems to speak of dealing with running it
as a service.

I just installed the updated version of PostgreSQL 6.4.2 on Linux 2.2.2.  I
was able to compile and add the ZPyGreSQL Product to my Zope installation.
I want to create a Database connection.  When I go to create a new one, it
asks for the Id, Title, and Database Connection String.  What do I put into
the Database Connection String?  I tried the database I want to use, but it
gives

Invalid connection String: baseball

Is it a rights issue with PostgreSQL or something else?  What is it
expecting the database connection string field anyway?  Thanks for your help!

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC4A@peter.sths.org>

I have a nifty system whereby each individual I add to a database
automatically gets a personal directory and password. One of my users
has come to me with a problem. He can add images to his directory, but
cannot subsequently edit the image (i.e. open the image's manage screen)
as it complains about lack of permissions. The security role he has
contains all the image related options I see. He can delete it, btw.
This is not an immediate issue, but I do wonder why the permissions
don't seem to be working in a sensible manner. Why should he be able to
add images, but not manage them? Are there extra 'image manage'
permissions? If so, where do I find them?

Subject: [Zope] FAQ 0.2 - About this FAQ
Message-ID: <36E56988.CEF76199@pop.vet.uu.nl>

Zope FAQ 0.2 - About this FAQ and the Zope Documention Project

* What is this FAQ?

    This FAQ is a project of the Zope Documentation Project, and aims
    to answer any (or at least lost) questions you might have about
    Zope and how to use it.

* What is the Zope Documentation Project?

    The Zope Documentation Project (ZDP) is a community project of
    Zope users that aims to create documentation for Zope. The first
    goal of the ZDP is the creation and maintenance of an extensive
    Zope FAQ, later on other documentation will follow.

    We welcome everybody to contribute; for instance by sending in
    questions and answers for the FAQ.

* Where is the rest of this FAQ? 

    The Zope FAQ has been split into separate sections. If you are
    reading this on the ZDP mailing list, you should see the other
    documents posted as well.

    If you are reading this on zope@zope.org or zope-dev@zope.org, you
    will only see this message. The Zope FAQ is under development. It
    is probably already useful, but because I don't want to spam
    everybody you will have to look at the ZDP list to see the rest of
    the FAQ. Everyone is very welcome to join the ZDP list. 

    You can also wait until the ZDP has its web infrastructure going
    and the FAQ is published on the web. This will hopefully be very
    soon; we're working on it.

* How do I contribute?

    The Zope Documentation Project has its own mailing list
    (zdp@zope.org). You are encouraged to use this list for all ZDP
    related communications. Please do not send your messages (such as
    FAQ contributions) to Martijn Faassen (the current FAQ maintainer)
    if your message can be sent to the mailing list instead.

* How do I join the ZDP mailing list?

    You can subscribe to the ZDP mailing list by using the page::

        http://www.zope.org/mailman/listinfo/zdp

    Thanks in advance for your contributions!

* Are there other Zope-related FAQs?

    Yes, there is the "Zope Questions and Answers" at::

        http://www.zope.org/Information/QA/

    This is maintained by Digital Creations; currently it is the best
    place to look if you are brand new to Zope.

    That said, Paul Everitt of Digital Creations has kindly
    contributed the Zope Questions and Answers to the ZDP (or vice
    versa; the ZDP is contributing to the Q&A). The ZDP plans to merge
    the two FAQs shortly.

* What is Structured Text and what does it have to do with this FAQ?

    The FAQ is (currently) written in Structured Text, so you may very
    well reading the FAQ in Structured Text format (the double colons
    and the indented paragraph structure give it away). If you are
    just reading this FAQ you shouldn't worry about it. 

    If you plan to contribute to the ZDP we'd prefer it if your
    contributions were written in Structured Text, however. For more
    information see the Structured Text section of this FAQ.

* What are these FIXME comments I see scattered through the FAQ?

    If you are reading the ZDP mailing list or its archives, then it
    is the FAQ's editor (or possibly a contributor) who is not
    entirely sure about some details on Zope, and is asking people on
    the list to help figure it out.

    If you are reading this FAQ somewhere else, then oops, they don't
    belong there. Please send a message to the zdp@zope.org list
    telling us about it, and thanks!

* What other sections does this FAQ have?

  We currently have sections on:
  
      o DTML
 
      o Zope Administration

      o Structured Text
 
      o External Methods
   
      o Builtin Products

      o Product Development

I have a problem with authorization under Apache 1.3.3

get Athorization failed, and when I pres cancel I get the traceback
below.

I have put the lines (with modification reflecting my placement of

wasn't sure where to put it, since according to Apache documentation the

What does the line "Zope configuration maps /Zope/ to the Zope.cgi cgi

cgi-bin, put the above lines into srm.conf, and restart Apache...

You can try it on http://www.sol.cz/cgi-bin/Zope.cgi. name is superuser,

Subject: [Zope] Root Folders and Names {Manager's Guide Update}
Message-ID: <02c001be6a6d$a24716e0$0201a8c0@hawkeye.bob.oc>

* How do I "name"  the *blank* root folder?

This is the same folder that is named "Plutonia" in 
the Zope manager's guide. 

Maybe the root folder has no name so
that if I go to  http://www.bob.com/  the 
"Folder at /     " will present index_html 
to requesting browsers.

If I did name it "plutonia" would it be accessible
both as
http://www.bob.com/   and as
http://www.bob.com/plutonia  ?

So maybe I don't need to "name" this root
folder.  If so, then the Zope manager's guide needs
to be clearer. In the fourth paragraph on page 12 
it says:

"...presuming that your ZOPE is installed at 
http://your.place.com/Objects and it's management
screen is at http://your.place.com/Objects/manage"

This does not follow through the document.
There is no folder named "Objects"

Maybe the document should say:

http://plutonia.com/ and it's management
screen is at http://plutonia.com/manage"

And to manage one of the three departments
used in the examples, say for 
example "News" then:
http://plutonia.com/news/manage"

Other notes on this issue: 
Timothy J. Grant asked:
"...My problem is that my Root folder in Zope has 
no name, and it appears that FSIMPORT requires 
a folder name for it to work."


No response was found to this post on 
the ZOPE list.

I've gotten Zope up and running on my IIS/NT server. Right now I can access it 
through www.myserver.com/cgi-bin/zope.exe. Is there any tricky way to get it to 
run as www.myserver.com/zope? including www.myserver.com/zope/folder/object?

Can you do that with Apache on NT?

I would use ZServer but I need to also be able to run Perl CGI scripts.

Right now you can't. And you don't need to. The "name" of the root folder
is simply the SCRIPT_NAME your webserver uses to access Zope. By default in
ZServer and ZopeHTTPServer this is an empty string, since they both
normally server one published module, though they both can server multiple
published modules.

So, you can give your root folder a title, but you can't use Zope to change
how your web server calls Zope. Do this with your webserver. In the case of
ZServer, check out the zope_handler.py, it has options to set the
SCRIPT_NAME. ZopeHTTPServer also has options to set the SCRIPT_NAME with
command line arguments.

>So maybe I don't need to "name" this root

Right.

>If so, then the Zope manager's guide needs
>to be clearer.

Perhaps the docs should be updated. The manager's guide probably assumes
that you're using PCGI, but it shouldn't make this assumption.

Hope this helps.

Subject: [Zope] ZSQL methods in parent subfolder
Message-ID: <Pine.LNX.3.96.990309162504.454A-100000@taos.kavi.com>

Is this behaviour a bug?

I have all my ZSQL methods collected together in a folder. If I call these
from a sibling folder[1] without any arguments, ie.

<!--#in "sql.company"-->

I get the below error, if I call them with specific arguments, ie.

<!--#in "sql.company(comp_id=_['comp_id'])"-->

I get no errors. (comp_id was in REQUEST in both cases).

[1] by sibling folder I mean something like the following arrangement...

/sql/company  		(where the sql method is stored)
/lists/company_list 	(where the call is made)

Here's the error:

<!--
 Error type:  
 Error value: 0

Looking into it, line 332 in Aqueduct.py is a simple key lookup...

    def __getitem__(self, key): return self._data[key]

It would seem that an argument is getting passed in by default when the
sql in put in a parent's subfolder.

Subject: [Zope] Q: Setting/Creating variables
Message-ID: <Pine.LNX.3.95.990309165933.6532A-100000@animal.blarg.net>

I have been playing around with Zope/ZPublisher/DocumentTemplate and have
been extremely pleased with the ease of development, as well as the power
of the Python language.

Sometimes I have found myself wanting to save the results of an expression
in my DTML code, for use later in the same page (or even an embedded DTML
object).  The only thing I have used that is similar to DTML is
ColdFusion, which has a CFSET tag, ie: <cfset myvar = "test"> or
<cfset total = subtotal * tax>

In reading the docs, it looked like I might be able to do something along
the lines of <!--#call "REQUEST.set('var', 'value')--> but this didn't
seem to work, and it's not very elegant either.

Am I missing something? None of the howtos or tutorials seem to cover
this.  A <!--#set newvar=oldvar--> / <!--#set var="expr"--> would be
really spiffy. =)

Please make sure you CC me if you respond to this message, as I had to
unsubscribe due to the overwhelming amount of traffic.

Thanks!

Subject: [Zope] tree doesn't work 4me linux amd win32

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?



I had the same problem, but only with Zope 1.10.2.  I noticed that DTML
documents (the default to be created) won't work with the tree tag.  If you
create a DTML Method (like the old DTML from Zope 1.9) then they work as
expected.  I don't have a clue as to why this works like this.  Maybe its
the proerties of the DTML Documents that are acting folderish and tree
doesn't know what to do?

Hope that helps,

Message-ID: <4.1.19990309224955.009de8f0@10.0.0.1>

We have been unable to access properties of the new DTML Document objects
in the same way we used to access properties of Folders. 

I don't know whether we are doing something wrong or we found an
inconsistency in the new 1.10 Zope API.

Here is a very simplified test case illustrating the issue.

I have a folder with these contents:

folder1 [Folder]
- broken_html [DTML Document]
- index_html [DTML Document]
- sub-document (The Grand Sub-Document) [DTML Document]
- sub-folder (The Grand Sub-Folder) [Folder]

The source of index_html (which works) is:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-folder'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-folder'].author"--></p>
<!--#var standard_html_footer-->

This works as expected. The properties title and author of the sub-folder
are retrieved.

The source of broken_html is exactly the same, except for the sub-document
reference:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-document'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-document'].author"--></p>
<!--#var standard_html_footer-->

Viewing this document-method I get a "Zope Unavailable" message with this
traceback:

<!--
 Error type:  
 Error value: 'string' object has no attribute 'title'
 -->
</BODY></HTML>
<!--

So, how do I access properties of sub-documents from a sub-document in the

One way is to use DTML Methods instead of DTML Documents.

Nope, ZHS (for short) is derived from the example CGIHTTPServer.py that
ships with Python---it's heavily modified though.  ZServer is what is
derived from Medusa and is currently in alpha (though pretty stable for
me).

As for SSL, not currently, and I'm not sure what's going to happen with
this.  You can use Apache+SSL right now for this.  I've had some
thoughts about it, but I'm not sure how SSL will impact an async-socket
based system...  the setup of new SSL connections is kind of heavy.

I am using:
Red Hat 5.2
Zope 1.10.2

- I created a username of "zope_u" and a group "zope"

- I did run the installation script with a command line like:
        ./install -sAdmin:MyPassword -u zope_u -g zope

- I created the Feedback and SendFeedback forms as per the manuals.

- I added the user "zope_u" to the mail group.

- I modified user zope_u's .bash_profile file to include the path to
sendmail in /usr/sbin

- If I log-in to the Linux server as zope_u, I _am_ able to call sendmail
and to send mail outside of the server.

Anything else I missed, folks?

Regards.

I understand the difference between DTML Methods and DTML Documents. 

The very reason I chose to do it with DTML Documents was to be able to
store some special fields, such as 'author' in my example, along with the
document. I cannot do that with DTML Methods, as they do not have properties.

In Zope 1.0.9 I used folders but I was running into problems with relative
links. It seemed natural to switch from my previous folders to the new DTML
Documents.

I still do not know to reference the properties of a DTML Document 'A' from
within a document or method 'B' in located in the same folder as 'A'.

Thanks for any help.

You are right. I was using folders too for the same reason.

You can use the PARENTS variable.

so if you have a folder which contains two DTML Documents A and B then
you can access B's properties from A by:
<!--# var "PARENTS[0].B.name"-->
PARENTS[1] will return the folder or containing object one level up and 
PARENTS[-1] will return the top most Folder.

Thanks for your help, Pavlos. I found another way. Instead of writing:

<!--#var expr="_['sub-document'].author"-->

I wrote this, and it worked fine:

<!--#var expr="_.getitem('sub-document').author"-->

I found a way, but I don't understand why the first syntax worked fine with
Folders and fails with DTML Documents. If anyone would like to clarify the
semantic difference between _['sub-document'] and
_.getitem('sub-document'), I would be even happier.

By the way, Pavlo's site http://www.gaaros.com:9673/ is useful!

The answer is in both the ZDP's FAQ and the DTML Manager's Guide. 

_['foo'] "renders" foo according to DTML rules. This process mostly
consists of calling DTML and other callable objects.

_.getitem('foo') simply returns foo as found in the DTML namespace.

The reason you were having problems is that _['sub-document'] renders the
document to a string. Naturally strings don't have properties. Hence the
error you got from Zope, "'string' object has no attribute 'title'".

Make sense?

Message-ID: <Pine.BSF.4.05.9903092345060.330-100000@guru.phone.net>

I'm trying to get zope working to study it, but keep stumbling over
the "(102) failure during connect" error - with the "No such file or
directory" addendum.

The underlying OS is FreeBSD 3.1. I want to run it on an Apache web
server (at least for now), with the server doing the
authentication. That all appears to be working properly - after all,
I'm getting errors from pcgi, now, right?

The var directory is writable by nobody. In fact, the entire source
tree is owned by nobody, which is the user that the Apache httpd is
running as. However, I get log file entries from pcgi, even after
deleting the pcgi.log file. I initially tried copying the Zope.cgi
file to cgi-bin, but noticed that some (unspecified) setting in
Zope.cgi might need to change because of that, so I added a second
scriptalias to the Apache httpd.conf pointing at the source directory,
set the protections on it, and tried to load <URL:
http://localhost/Zope-bin/Zope.cgi/manage >. No change - the log file
records the same error message.

The pcgifile.py test reports 

	error attempting: 'from cgi_module_publisher import publish_module'

This doesn't appear to exist in the distribution - and I recalled
something about that being a holdover from bobo, so I removed that
test from the script, and ran it again. The modified version runs
cleans.

Was I wrong about cgi_module_publisher? Should it be finding that? If
not, then what's the next thing to look at?

FWIW, here's the entry from httpd.conf section for Zope:

SriptAlias /Zope-bin/ "/home/mwm/external-src/Zope-1.10.2-src/"
<Directory "/home/mwm/external-src/Zope-1.10.2-src/">

And here's Zope.cgi:

   You don't need hostname and port part, so the connection string can be
just "baseball user_name".
   (BTW, without host:port, libpq will connect to postgres using UNIX
sockets, not TCP/IP. I think it is much better - for speed and security)

Subject: [Zope] streaming data through zope from an external method.
Message-ID: <199903100907.UAA01717@mbuna.arbhome.com.au>

I've got an external method that is generating a (possibly quite large) 
audio file and sending it back. Right now, I'm generating this in memory
in a big string, then returning it to zope. I'd _like_ to be able to just
have the external method send the data straight through (maybe in chunks)
without having to read it all into memory. Is this possible with zope
at all?

Because you are calling "sql.company" (in quotes), it is assumed to be an
expression, and your expression is referencing an attribute, not a method.
Try using the following: "sql.company()", or sql.company (without quotes).
Note: I didn't test either method.

MailHost doesn't use sendmail, but rather opens a socket to the specified
sendmail host and uses the SMTP protocol to send the messages. This is
somehow prohibited. It looks like there is maybe no SMTP server listening
on the specified address and port, or your machine is not allowed to
connect. You could try and do a manual telnet to the address and port from
the zope_u account and see what happens.

Make sure you also go through the motions, like HELO <hostname>, and such.

Can #sqltest handle the 'wildcard' situation in MySQL (and probably 
other DBMSs too)

select * from tbl where tbl_val like '%nib%' is a different SQL query from
select * from tbl where tbl_val = 'niblet'

my attempt...

select *
from tbl where
<!--#sqltest tbl_val type=string multiple-->

I think the first problem will be finding a publisher that streams.
PCGI buffers all I/O, perhaps FastCGI doesn't.  Even if you didn't,
sending it through Zope in chunks would avoid getting Zope's memory
footprint up there.

One way would be to have the ExternalMethod return a sequence, then do
something like:

<!--#in myExtMeth-->
  <!--#var "RESPONSE.write(sequence_item)"-->
<!--#/in-->

Of course the above might be completely wrong, but you get the drift :^)

Yes, it's a holdover from Bobo days (which some people are
still using for existing apps) but you can ignore that
particular error.

Contact me offline and we'll try to get this resolved.

Try::

   <PRE><!--#var REQUEST.form--></PRE>

or::

   <!--#in "REQUEST.form.items()"-->
      <LI><!--#var sequence-key-->: <!--#var sequence-item-->
   <!--#else-->
      No form items
   <!--#/in-->

To generate an overview of all form variables your DTML has access to.

Thanks for the suggestion Martijn but I've already tried that and it does
indeed show variables of the form 'answerbtn.x'.  But when I try to access
them using one of:

<!--#var answerbtn.x--> or
<!--#var _['answerbtn.x']--> or
<!--#var _.getitem('answerbtn.x')-->

I get a traceback error, so I am none the wiser 8^(

Thanks anyway

Any other ideas?

Read my reply to the orginal message in this thread as to why the tree
tag doesn't work as you expect in DTML Documents.

Nope.  ZopeHTTPServer is not Medusa, it is based on the HTTPServer that
comes with Python.  Medusa is it's own product, that we have integrated
parts of into ZServer (which uses the core of Medusa to drive it's
network end).

http://www.nightmare.com/medusa/

For medusa info.  http://www.zope.org/ for info on ZServer.

Once ZServer is stable (it is alpha at the moment) use of ZopeHTTPServer
will be depreciated (but not forgotten).

Subject: [Zope] New subscriber: Installing Zope
Message-ID: <199903101525.KAA25149@mail.howard.k12.md.us>

Having seen Zope recommended on Usenet last week, I decided to check it 
out, Monday I found the Webreview article in the email box.  I have been 
reading as much as I can find, but one question is always on my mind, 
when ever I find one of these wonderful, does it all systems.

Can I install it ?  Not, is it to complicated to install, but do I need 
root access to the machine to install this application.  This question 
and the answer have killed many a promising application (DB & BBS).

So, the question is, can Zope be installed in a typical Telnet account ?

The install docs mention, you have to be root user, to install some 
components, does this mean what I fear it means ? (machine admin, ie. 
super user)

Yes.  I am trying to reference a folder that is not in the same path.
And I tried your next suggestion a long time ago, with no luck. 
<!--#var candidate1.name-->, and get an error with traceback:

<!--

This doesn't work.  My paths are like, /staff/candidates/candidate1, and
staff/companies/company1/job1/submission1/MyDocument.  I am trying to
reference a property of the candidate1 folder in the MyDocument
document.

Hmm,

More on the image button saga.

It seem's that <!--#var answerbtn.x--> does indeed work, but <!--#var
_['answerbtn.x']--> doesn't, and neither does the getitem way.

Seems weird to me, any ideas?

TIA

You should be able to install a binary package as a typical user on a
UNIX machine.  If your machine already has Python 1.5.1 or higher
installed (don't they all?!?!?! :-) then you can just install the basic
source distribution of Zope and do the:

	$ python wo_pcgi.py

Thing :-)  You can then use the ZopeHTTPServer on a untrusted port (over
1000) and off you go :-)  If you want to use Apache+PCGI you probably
will need administrator support, and if yo uwant to be on a port under
1000 you'll need it.

You should be able to get a feel for it without being root.

Try Zap, the precompiled apache for Zope (Linux only).  The zap.conf
file will probably have something your not including in your apache.
also, do an 'httpd -l' and make sure you have mod_rewrite compiled
and/or dynamicly loaded in.

<!--#var "candidates.candidate1.propertyname"--> will work.

candidates is the object that is the common ancestor, and from there you
can reference objects down that path. You will have to place the expression
into quotes, however.

You can indeed install it. I had originally had a standard telnet 
sort of account on a FreeBSD machine. You can basically get a 
full-featured Zope if your web provider runs apache with mod_rewrite.

Zope 1.10.2

I have a ZSQL method for inserting data into the database.
The database connection is active.
the permissions are correct.
the method is defined roughly as:

insert into tblname (col1, col3, col4, col5) values
(col1val, "value taht is constant", col4val, col5val);

when I try and test it, Zope tells me that there
is a parse error near ';'.

I remove teh ';' and Zope tells me that 
"This was not a query."

I'm missing something, and I'm hoping it's not my 
mind . . . any help?

(oh, nad yes, the query works just fine when entered
by hand in a mysql or xmysql connection)

Subject: [Zope] title and id properties in DTML methods
Message-ID: <36E6A70C.687B26BA@pop.vet.uu.nl>

Hi everybody,

I'm probably completely confused, but if I understood it right, DTML
Methods in Zope 1.10 are the same as Documents in Zope 1.9. I may
remember wrongly, but wasn't it so that

<!--#var title_or_id-->
<!--#var title-->
<!--#var title-->

in 1.9 documents rendered the title and id of the actual document, and
not that of the containing folder? In 1.10 in DTML methods, they appear
to render the containing folder, instead. The only way I can access
title of a DTML method in 1.10, is by referring to it specifically, i.e.
<!--#var "some_method_id.title"-->.

It works as expected with DTML Documents.

Is this as it should be? Am I correct about the 1.9 behavior? If so,
then DTML Methods don't seem to be exactly equivalent to 1.9 Documents,
and this should probably be in the FAQ. :)

Regards,

Martijn

Do it without the ';'. When it says 'that was not a query' it simply
means that there was no returned results for it to display. If you check
the database, the values should have been successfully inserted.

If you're doing just a single query, you don't need the ';' (or its
equivilent).

If you're doing multiple queries, use <!--#var sql_delimiter--> to seperate
them.  The DA will seperate the queries using this.  This is equivilent to
what command line or other SQL tools often do with the ';' character.

> I remove teh ';' and Zope tells me that
> "This was not a query."

Nothing is being returned is what this means (or more basically, it wasn't
a SELECT based query).

I can't use another apache just for Zope. I looked into zap.conf and
incorporated some changes into my httpd.conf. No way.

Since the log file of RewriteLog remains empty, I believe no rewriting
takes place, actually. I have about 30 virtual servers on that httpd,
maybe there lies the problem? Also this is Apache 1.3.3, do I need
Apache 1.3.4?

hi!

No. Zope works fine with Apache 1.3.3. Did you remember to set the ExecCGI
option? And did you remember to turn the RewriteEngine on?

Yes I turned rewite engine on, but maybe not in the right place. I wrote
it into global config.

I believe do not need to use ExecCGI, since I use ScriptAlias. And
Zope.cgi gets executed, I otherwise wouldn't be able to get to Zope
introductory. 

I'm desperate....

Something in an external method similar to this should do the job.

from string import split, join

def stringtounderscore(str):
	return join(split(str," "),"_");

which is then called from your page as 
<!--#var "stringtounderscore(mystring)"-->

Alternatively, if this is something you only need occasionally, you can
code it directly in DTML...

<!--#var "_.string.join(_.string.split(mystring,' '),'_'"-->

Both of these are untested, but I have tested the join/split command in
python directly:

>>> join(split("this is a test string"," "),"_")
'this_is_a_test_string'
>>>

You can use something like:

<!--# var "_.getitem('foo',0).whateverproperty"--> (Is 0 the default?)

_.getitem('foo',0) returns a reference to the object with id foo.

Thanks for a very fast reply, however it doesn't work. I'm still getting:
Error value: 'string' object has no attribute 'title'.

This is what I'm trying to do:
A DTML document (index_html) has a property art1 which has an ID for another
DTML document as value (type: string). In index_html I use: <!--#var
"_[_[('art1')]]"--> which renders the article. I can of course use
<!--#var title--> in the actual article, but I rather don't. So I'm still
banging my head in the wall after hours of trying to accomplish this. Can it
be a bug with DTML documents??

I think that DTML Methods (or Documents?) are meant. They are like
methods to the folder objects that Zope publishes. Look at:
http://localhost/Zope/foo/bar/doc as asking Zope 'okay, folder 'foo', I
want your subfolder 'bar' (this could be seen as using a method on foo
to request 'bar'), and then I want to view 'doc' (which is, let's say, a
DTML method) in bar. 'doc' in that case is a method of the bar object,
which, when called, returns HTML code (to the browser).

An *external* method is a method which comes from outside the Zope
object database (though it's loaded into it, and behaves just like a
normal internal method).

If all this talk turns out to be correct (somebody tell me or send
corrections), then I can turn this into a FAQ entry. If anybody else
feels like writing this up in a nice way for the FAQ (Oleg?) that'd even
be better. Just send your contributions to the ZDP list.

Hi!

   That is, there are DTML Scripts and External Methods. Python code is
used in External Methods and Products, but never goes into Object Database.

I think it's true Product python code doesn't go into the Object
Database, but I'm unclear about what happens with External Method python
code. You need press the 'edit' button for an external method in Zope
each time you changed something in it and want it updated. This would
imply Python code can indeed be part of the Object database, right?

I can confirm this; this one bit me too, I recall. Can anyone write up a

Actually not. For security reasons the code of an External method does
not reside in the Object Database but in the filesystem. When you press
the 'edit' button the code is read and evaluated and it is the evaluated
code that is stored in the Object Database. There was a thread about
whether the source code should be included in the Object Database but I
think thge Digital Creators were not convinced.

How are more than 1 value submitted from a form? How can I get those values

Help is much appreciated!

No, it forces Python to recompile the code. The code itself is NOT stored
int the object database. Only instance data is stored in the object
database, no code is. Zope classes are said to change all this, aren't
they, DC?

Pressing the 'edit' button "reloads" that particular External Method code
into the system.  It's not stored in the database at all - the External
Method object you add/edit through the Zope management screens is primarily
a pointer/wrapper to a method in a module in the Extensions directory.  The
Edit button in essence acts similar to the reload(module) function in
Python.

Basically, Zope (and Python) don't have a way of knowing the code in a
module has changed unless it's explicitly reloaded, which is a good thing.

Well this is how I understood the process.

Basically the code is read and exec-ed and the the func_code
func_code.co_varnames are extracted. Then they apply all the clever tricks
to turn the function into a valid Zope method, by (I assume) creating a
Zope method and replacing its func_code and the associated func_defaults
and arguments with the ones extracted from the external function.

The relevant code can be found in
Zope/lib/python/App/Extensions.py and
Zope/lib/python/Products/ExternalMethod/ExternalMethod.py

External Methods are (to the best of my knowledge) evaluated and their
compiled code is kept in process memory (effectively cached) the first time
the object (the External Method object pointing to a particular
module/method) is activated.  It is removed from process memory when the
object is de-activated.

This is kindof a tricky process and may be effectively cleaned up in the
near future so I won't go into too many details here.  An important thing
to keep in mind is (again, this may change soon) that the compiled code is
kept locally in each External Method Object.  If you have two EM's in Zope
pointing to the same code, you have to use the "Edit" button on _both_
External Method objects to effectively reload it.

When you say that you made it so that Apache handles the authentication,
I take that to mean you have created a .htaccess file? If that is the
case, Apache will always prompt for the password and check it against
your password file. If you use mod_rewrite to let Zope handle authentication,
you will not see the password prompt for resources that are available
to anonymous users.

Thanks! Although by now I knew most of what was mentioned (though it
sure was nice seeing it all together in one place) this will be
invaluable for people who want to get up to speed with DTML.

Excelent! This is so much clearer than isolated answers to 'how-do-I'
questions. This gives me the context I've been missing!

Message-ID: <Pine.LNX.4.04.9903111551260.32022-100000@dolemite.psionic.com>

Hello,

I've looked through all the docs, FAQs and threads of the Zope list for
some of these answers and haven't found a clear method described. I'll
apologize now if the questions seem obvious, but I'm new to deploying Zope
on a web server and need some initial Zope setup guidance.


Question 1: 

Under Zope, what is the proper way to configure the website so users can
simply go to http://www.example.com instead of:

http://www.example.com/example
http://www.example.com:9673/
etc.

My understanding is that the mod_rewrite rules will have to come into
effect here. Will I also need to do a re-direct of some type? I need
some way to direct all URL requests so they are re-written to point to the
correct Zope folder. The ideal for me is to have a series of folders in
Zope that contain separate websites. The sites can be virtual hosted as
needed (although right now I'm only running one site). I can't find a
clear description of how to make this happen. Also I don't want to run a
separate Zope process and proxy people to the port. I want to have
everything running on port 80.

I'll have to agree with other posters that a tutorial on the design of
the actual Zope site with Zope would be very helpful as they are using a
layout of html and hierarchy that is very similar to what I'm pursuing. In
fact if someone could provide me with a description of the config they're
using it would be a huge help.


Question 2:

Under .DTML construction of links is it generally considered "better"
Zope practice to reference the entire URL or the Zope object hierarchy
directly?

Question 3: 

I don't want tracebacks to appear under any circumstances to the end
users. I haven't tried anything to counter this yet, but wanted to know
what some others have done. Would an approach to this be a try/except
positioned in the standard_html_header and footer files? Ideally I would
like to catch all exceptions and have it automatically mail the exceptions
to the webmaster instead of showing the user (In fact I think this would
be a good feature for the product). 

Question 4:

Has anyone pursued a security audit of the Zope code? I've been
considering doing this (not that I don't trust the Zope developers,
it's just that I don't trust anyone) and would like to work with
others if possible. Several of the sites I admin get hacked on very
frequently and I'm a little nervous about replacing static web pages with
no CGI running anywhere with the exact opposite end of the spectrum with
Zope. :) 

I'm also going to prepare a document describing how to run Zope
in a chroot() environment under UNIX to increase security. I'll let the
list know when it is complete.

Thank you for any responses,

-- Craig

I'm new to this list.

It seems to me that the www.zope.org is rather slow this week.  Documents
are taking far too long to be parsed.  Pings seem reasonable, so I am
expecting that the server may be receiving a lot of requests and being
overloaded (maybe from the Web Review article).  So I am just wondering what
the specs of the system that the www.zope.org ISP is using.  Also wondering
about stress tests and benchmarks for the Zope system.  (It must also depend
on backend systems etc)

Hi,

	Using Zope 1.10.2 on Win95, I was trying to set permissions on
a DTML Method. I was trying to set everything except "View" to the
Acquired permissions. View was turned on only for "Manager" and "Editor".
When I click the change button after setting things as I just described,
I get the following Traceback:

Traceback (innermost last):

AttributeError: manage_addProperty


If I'm not doing something foolish here, I'll submit this to the Collector.

Thanks!

Use Apache's VirtualHost ability...
Look here for more info: http://www.apache.org/docs/vhosts/
An example:

# in httpd.conf

# your ip
NameVirtualHost 192.123.44.3

# your standard host.domain (this must come first)
<VirtualHost 192.123.44.3>
ServerName your.standard.name
DocumentRoot /home/httpd/html
</VirtualHost>

# one or more extra virtual hosts
<VirtualHost 192.123.44.3>
ServerName your.zope.name
DocumentRoot /home/httpd/html
RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 \
	[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

I'm the guilty party (!)

I found this problem before but so far haven't found the fix.... here's what
I originally posted to the list.

I'd like to get this sorted out as I'm also working on a Souped (Zoped?) up
version of Amos's poll product, which produces pie-chart gifs in response to
the poll results, but it also broke in much the same manner going from 1.9
to 1.10. So any help on this matter would be much appreciated!

Cheers,

Andy.

Subject: RE: [Zope] Guestbook Product


I get the same thing :(

Hmm.. looks like DocumentHandler no longer exists.

I've taken out DocumentHandler from the Guestbook, to mimick the change that
has been made to 'Folder' going from 1.9->1.10. When doing the guestbook, I
kept making sideways glances to Folder.py to see how it was done ;)

The book no longer crashes but I'm getting some other wierdness. The
guestbook is a folderish product which contains two documents that the user
can add to change the appearance of the guestbook. They're added by the
following lines in the 'add' method ...

        # Add a Document used to view previous entries
        fileName = os.path.join(prefix,'index.dtml')
        index2 = open(fileName,'r').read()
        i = DTMLMethod(index2,__name__='index_html')
        print "i is %s" % i.meta_type
        i.title='Change me to determine how entries are viewed'
        self._setObject('index_html',i)
        print "ObjectItems is %s" % list(self.objectItems())

The added objects no longer seem to be showing up in objectItems().

The debug statement, when run on 1.9 prints out the newly added object in
the call to 'objectItems()', while on 1.10 it returns an empty list. Is this
a side-effect of the removal of DocumentHandler? I thought that _setObject
was being inherited from ObjectManager, so wouldn't be affected by the
removal of DocumentHandler.

Cheers,

Andy.

Well, under RedHat 5.2, mod_rewrite is a DSO, and is activated
in the *middle* of the httpd.conf.
I had the same problem. The rewrite rules put a the top of the file
have no effect because they occur *before* mod_rewrite is activated.

I had to put the rewrite rules a the end of the file.
I works now.

I don't know if this will solve your problem, but, just in case...

Hello,

Correct me if i'm wrong: one has got to have "access content informations"
permission to be able to write:

<!--#with Folder--><!--#var title_or_id--><!--#/with-->

right? I've been bitten with that, and once i gave "access content
informations"
to the Anonymous User, my problem went away.

Also, before I submit this to the Collector, is it normal that the "use
mailhost services"
doesn't appear in the security tab of the folders? Each product has its
permissions
that are listed, but nothing with the mailhost object.
I had to change it directly in the mailhost object.
If it's normal, it means that i can't give global permission for mailhost
objects???
What confuse me, however, is that the mailhost object claims to "acquire"
permission
settings from its parents, but nowhere in its parents i can define the
permissions.

Hi all ,

We try to use DocumentTemplate not for HTML dynamic generation but for
C++ generation. For convenience, and because we are familiar with Python
we intend to use the Alternate Python String Format Syntax. The
generation code is beautiful compared to our previous output.write("blah
blah.... ") instructions.

Reading the docs, looking at the Zope site, this behaviour doesn't seem
to be shared by a lot of zope users. Moreover the Alternate Python
String Format Syntax  is poorly documented, and DTML features seems to
be usable but the way they can be used seem very strange. Basically our
needs are to use conditional structures, iterative structures and to
call methods. The last point seems to be the hardest one. The following
code shows a way to call python methods in python strings but 3 persons
during half a day have been necessary to find it out.

I suppose you can imagine my questions :

Is there a natural and convenient way to find out PSFS expressions going
from their DTML equivalent  ?
Is there a complete documentation on PSFS syntax ?
Are the features of DTML and PSFS identical ?
And the most important :
Do you encourage us to keep on using PSFS instead of DTML ?

Thank for your help
Stephane

Well you were both right. I have turned on ExecCGI for my standard
cgi-bin directory, where I placed a copy of Zope.cgi. It is NOT
neccessary to add <Directory> statement for /usr/local/zope/ (I thought
it was neccessary... so I'm writing it here for the upcoming FAQ). Also
I thought that I should use http://www.domain.com/cgi-bin/Zope.cgi
address, which brings the introductory screen (that fooled me) but does
not allow authorization. The correct address is of course
http://www.domain.com/Zope, since that's what the rewrite rule is about. 

Thanks to all who helped me!

Hi Ron.  Just a guess, but how about having the tree tag pass in the the
current level as an argument to the same SQL method, then have the SQL
method adapt itself based on the argument?  Remember that an SQL method
can embed logic and act like an object using DTML.  For instance:

<!--#if "level==1"-->
  select ...
<!--#elif "level==2"-->
  select ...
etc.

The installer for the Zope NT binary asks you if you want to run as a
service -- in fact, that's the default.  Take a look at the file
"doc/INSTALL.txt", under Installation on Windows, for more information.

I'm not sure if the Zope universe is big enough yet for that.  I rememer
Guido doing this for Python about a year ago and nobody showed up. :^)

Perhaps if there were coordinated events?

I think the answer will certainly be yes.  Go to:

I do hope there is. If implemented like the Apache JServ module
(http://java.apache.org/) it should solve a lot of problems for everyone,
adding performance to boot.

JServ is in effect a separate process (like Zope) that receives it's
request via the Apache server, with the help of a module, that translates
the requests into socket calls.

If someone modifies the module that comes with JServ to call the Zope
process instead of the JServ process.....

HI all,
In my quest to figure out how Zope works, I'm starting with ExtrenalMethods.

I've moved slashdot.py into Extensions and set up an external method 
(id: get_headlines, funstion name: get_headlines, python module: 
slashdot).

My 'calling' DTML is a method (slashdot_headlines) with the following;
<!--#call get_headlines-->        
<!--#in headlines mapping-->
<p>
<a href="<!--#var href-->"><!--#var title--></a>
</p>
<!--#/in-->             
trying 'view' on this method gives the following;
<!--
 Error type: 
 Error value: read-only buffer, class
 -->
...
<!--
Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module

-->

I *did* have a problem with using a proxy, but got around that by 
adding this line to slashdot.py (just before the urllib.urlopen() 
call).
urllib.URLopener(proxies={'http': 'http://cache-box.you.domain:your_port'})

What am I doing wrong?
many thanks

A mod_pcgi Apache module has been discussed.  It would certainly
be more efficient.  One of the issues would be whether pcgi
should get out of the process launch business, which would
simplify a mod_pcgi and make it easier to debug.

Ok, I'll check that out.  My experience has been than I run it with
start.bat and when I close that ms-dos window zope stops.

I think that now that zope is "out there " and is open source that you will

If your external method is called from DTML document 'foo' then something
like this should do it (untested):

def mymethod(self):
	if not self.hasProperty('myproperty'):
		self.manage_addProperty('myproperty','hello','string')

BTW you can achieve the same effect from DTML

<!--# unless myproperty-->
<!--# call "manage_addProperty('myproperty','hello','string')"-->
<!--#/unless-->

This is a buglet in ExternalMethod where an exception has been raised and
caught by ExternalMethod, and EM is looking at the values of the traceback
for some special conditions.  It's trying to do a string.lower() call on
one of the values that in Python1.4 was always a string, but in Python1.5.x
is an instance (in Python 1.5, standard exceptions became classes).  This
has been fixed and will be in the next release.

Welcome to the list Andrew! I'm glad you found my suggestions
interesting enough to check Zope out. Regarding my last email, did you
figure out how to do PUT and GET from DW yet? And do you know if
Macromedia is going to add WebDAV support to DW?

In case you missed it, I'd like to point you towards the Advanced DTML
Howto:
http://www.zope.org/Documentation/HowTo/DTML
as that has more thorough information than the DTML guide I showed you
before.

I would also be interested in a newsgroup, as I am currently filtering
the email into a folder and sorting it by thread, but a newsgroup would
let me see the the same threaded view from home, as well. This would
also have the effect of letting new users see the context of the current
posts.

Subject: [Zope] Access Control Advice
Message-ID: <Pine.LNX.3.96.990312123932.13260A-100000@taos.kavi.com>

Hello all,

I am working on a Zope app, and would like to see if anyone has any tips
for how I should handle access control in this situation...

The site is a corporate organization site. It has many corporate members,
each has an admin which has control over a subset of information kept in a
relational database.

I want to have just one role (comp_admin) for this. But each company can
only have access to their company info. Thus I need to check that the
admin belongs to that company. (there are also regular users who also have
to login. they can view, but not modify)

The users, passwords and roles are kept in the database too (UserDB).

Each company has a unique id, and this is the primary keys in the DB. Each
user is associated to the company using this id (a field in their table). 

Make sense?

My current idea is:

1. Have a general main page which both users and admins login to. If they
use the admin login, get their company id (comp_id) and create a link to
the admin section using the magic of direct traversal (this way they can
bookmark the admin page). Eg.

<a href="/comp/1/admin/">admin section</a>
('comp' is the zsql method, 1 is the comp_id, admin is the folder)

Thus the comp_id of the company will be available, and I could:

A. I could then (mabey?) use the comp_id in the UserDB query (in the admin
   folder) to only retrieve those people belonging to that company.

OR (if I can't get to the comp_id from the UserDB query).

B. I could then compare to the person's comp_id to the company's comp_id 
   in each of the effect pages via a new standard_header.

Thoughts? Better ways to do this?

I haven't tryed this but on pg 10 of DTML Users Guide check out:

maketrans(FROM,TO)
and
translate(S,TABLE[, DELS])

it seems to do character for character translations.

Brian built a pretty cool way to hook SQL entries to particular
folder trees for the PDMS.  Each folder has a uniqueid which is
stored in a sql table, along with the folder parent heirarchy, when
an item is added to the SQL database.  This allows each folder to
easily identify which SQL entries belong directly to it and which
SQL entries belong as children.  This allows one to easily do things
such as count the number of SQL items which are identified with a
folder tree using SQL query syntax.

Brian also provided dtml methods to move folders and their
relationships around in the Zope heirarchy quite nicely. The
mechanism holds quite a few SQL items in it and there has never
been a need for a Python or SQL god to do any maintenance on the
system at that level.

However, it does use both SQL and External Methods. So, don't
believe that just because something requires a fairly deep level
of competence to create that it requires that same level of competence
to maintain (me for example :^).  That's simply one mark of a decent
implementation.

Subject: [Zope] sequence of numbers
Message-ID: <9903121826.ZM7584@saab.coinet.com>

This may be a newbie question, but I've loked thru the doc and didn't
spot any obvious way to do this, short of an External Method.

What I want to do is given a limit number, iterate over a sequence of
DTML commands. This would be an obvious use for #in (which I'm using
elsewhere for other things) except I don't have a sequence - just the
number of items in the sequence, as it were.

In psuedo-code, what I'm after is something like this:
	for (i=0; i < <!--#var max_items-->; i++)
	{
	  // some DTML/HTML code using "i"
	}

Now if, given a #var, I could get a list - e.g.:
	<!--#var max_items--> --> list = [0, 1, 2, ... max_items]
or [1, 2, ... max_items], it doesn't make much difference.
then I could just use:
	<!--#in list-->
	// some stuff using <!--#var sequence-index-->
	<!--#/in-->

Is there an easy way to do this? Is there *any* way to do it?

Subject: [Zope] User Profiles?
Message-ID: <Pine.LNX.4.04.9903122303421.21162-100000@zeus.carolina.rr.com>

I am working on a web site for a local outdoors group. They have about
1,000 members and are growing fast, but their web site needs help. I had
lunch with their leader today, and strongly advocated the use of Zope to
redo their entire web site. He loved my ideas, and gave me the go ahead on
the site.

Now, my first question (I'm sure I'll have many) to the group is: How do I
create user profiles? Each user of the system needs to have specific
information associated with them including: full name, address, telephone
numbers, a picture (gif or jpeg, easily uploadable by the user), their
interests, a history of the events they've sponsored and/or attended, a
buddy list (basically just a collection of other member ids), and so on.

I have downloaded the UserDb product, and figure I might be able to extend
it to support the extra columns I require. However, a big part of me wants
to keep as much of this in Zope as I can. I like the idea of the
objectstore, and don't necessarily like having to fudge SQL tables every
time I add or remove an attribute from the profiles (not that I will be
doing that, necessarily).

What do those with a higher Zope Zen Rating than I suggest in this
situation? I'm also going to be making an Events Calendar, which is
connected up with all the User information (who's running the event, who's
signed up to attend, etc.). Is all of this something that Tabula would be
good for? If so, who do I have to sleep with to get it? :^) 

I am willing to write up a case study, testimonial, contribute any code I
write back to the community, etc., whatever is requested. I just want to
do a good job for these guys, making myself and Zope look good in the
process.

HELP! *grin*

I can see a  number of things that DW will (I think) do to  help out
Zope - but there is one item in the way - FTP support
There is no direct way for Dreamweaver to send pages back to Zope
without either writing to a filesystem via a LAN or by using FTP (no
webdav yet).

So my question is this - when will we get ftp support in zope? (not just
alpha).

I am looking at the dtml spec right now and thinking about building
drag-and-drop objects for DW that talk zope.
One thing I need is for someone on the zope team or elsewhere to help me
test these so that I get the syntax correct.

Recent notes about Lynx notwithstanding, I agree.  It's extremely
frustrating when debugging the security of an app!  Zope _CAN_ use a
cookie-based authentication scheme with the UserDB product.  UserDB uses
Database Adapter (e.g., Oracle) to connect to a store of user info
(e.g., userid and password).

I can imagine some motivated community member taking a look at the
current incarnation of UserFolder and UserDB and cookie-ifying the
UserFolder.

Since DTML already has at least two different syntaxes, would it 
be hard to give it another one, that used 'regular' tags? For getting-
user-acceptance purposes it would be really good to work with as 
many HTML editors as possible, even lame ones.

Having written the above, now I see that Jeffrey said it was a 
problem "with the current syntax" in his post.

Sorry if I'm raising a point that has been covered in a more

As I understand it, Zope hands the data stream to PCGI who then, outside

Here's a brute-force way to do it, as long as the list of items was
short:

<!--#call "REQUEST.set('foo',['1',
                       '2','3','4','5'])"-->

<!--#in foo-->
  <!--#var sequence-item--><br>

That's fantastic!  Well there are lots of people on the list that are

I predict we'll have something like this called a Membership System,
say, May 18th for a first cut.

If my previous history of fibs, spinning, obfuscation, and downright
lies makes you suspicious, or if you distrust my poor prognostication,
I'd suggest that you take the user objects in UserFolder and turn them
into extended DTML Documents, or perhaps even Folders.

There are many ways to do this, as you might imagine given
that Zope is a fully programmable environment. One such way
was done by Andy Smith (cc'ed on this reply) in building an
"alumni community site" for our (Andy and my) old
department. The site is http://www.ged.org. Unfortunately,
you won't be able to see much, as it's a password protected
site for members (there are two public pages). However, on
one of the public pages, you will note that it was the
intention all along to publish the source to the site for
the Zope Community at large.

As functional as the site is already, I think Andy had some
very cool extensions in mind before opening it up to the
public. Still, he can easily ship you the GEDUserFolder that
he built to keep track of everyone's contact info (easily
extendible to all of the fields you have in mind). As a user
of the site, I can assure you that it's a breeze to use!

Perhaps, this will also be incentive enough for Andy to
polish off some of his other goodies and release them :-)

Andy's stuff above is all kept in the Zope DB :-)

Tablua, what's that? Just kidding, it's now called Z Tables
:-). For the moment, we are actively selling (without
actively promoting) Z Tables. While you get the source, it
is _not_ an Open Source product. The license does not permit
redistribution of any kind, and does not permit derivative
works, etc. It does, however, permit you to use it to
operate any kind of website, including a publicly accessible
one, etc... The price is dirt cheap for the functionality
(IMHO). The license also has a clause that specifically
permits Digital Creations to eventually release Z Tables as
Open Source(tm). Meaning, when we're ready to release it,
don't be mad that you paid for it when others get it for
free... This is important, because it is our intention that
over time, the vast majority of our stuff will be Open
Source!

So, why do we charge now? A few reasons:

1) The docs are really weak. Rather than get beat up in
   public for it, we have a license clause that forces you
   to acknowledge that the docs are weak, and that you need
   to be able to read source to really understand the full
   power.

2) Support. Everything that we put out there causes a
   certain amount of extra work. The more sophisticated the
   code, the more work. Z Tables is _hot_, so if it were out
   there in its current form, everyone would want to use it
   (trust me on this one!), so it would become a support
   burden for us. Pay us for the product, and it's worth our
   while to support you!

3) Before putting out something to the world, we really want
   to make sure it's been beat up. It may sound strange that
   we would charge people to help us turn something into a
   polished product, but it's already powerful enough to
   solve real problems, so motivated users are our best bet
   to help us achieve our goals for a more general release.

See some earlier posts from people who have recently gotten
Z Tables! For example, check out a recent
"performance-oriented" post by Theodore Patrick of
Indigo Networks!!!

Subject: [Zope] INSERT Syntax with Zope & ZPyGreSQLDA
Message-ID: <87hfrp1js9.fsf@eurythro.savigny.stp>

Hello,

I'm trying to use PostGreSQL with Zope, but I'm having
problems using the SQL INSERT method in Z methods which
require parameters.

For example, I make a Z SQL Method named 'foo'.
In it:
INSERT INTO messages
VALUES
  (<!--#sqlvar auteur type="string"-->, 
   'blahblahblah', 'now', 'f')

I write the name auteur in the 'arguments' form.

Next I create a DTML document with:
<form action="foo" method="GET">
Auteur: <input width="30" name="auteur" value=""><br>
<input type="submit" name="SUBMIT" value="Envoyer">
<form>

When submitting the form, it displays me a new page
(generated by Zope) asking me again the auteur parameter,
as if the auteur variable wasn't passed to the Z SQL method :-(

Someone posted a mail recently with an example use
of INSERT, where he put '(auteur)' after the 'INSERT INTO messages'
text: INSERT INTO messages (auteur) ...

When I try this, I get:

Error, pg.error: server fatal error. Please report to your db administrator. 

SQL used:

INSERT INTO messages (auteur)
VALUES
  ('testing again', 
   'blahblahblah', 'now', 'f')

Is there something specific to PostGreSQL ?
(Using Zope 1.10.2, PostGreSQL 6.4.2, PyGreSQL-2.2, ZPyGreSQLDA 0.02)

I looked in the Z SQL Method User's guide, but nothing is written
about adding data to a DB :-(

A good to test your SQL is using psql.

And upgrading to PyGreSQL 2.3 or later, which return proper sql messages

This is definitely wrong ;(

something like 
INSERT INTO messages (auteur,title,bookdate,any_good)
VALUES
  ('testing again',
   'blahblahblah', 'now', 'f')

might have worked. You may also mean current_date or current_time 
instead of now or now()

I didn't find any other way, either. But here's an External Method you can
use.

--- begin loop_range.py ---
LoopRangeError = 'LoopRangeError' # Name an exception class.
loop_range_limit = 100            # Maximum allowable loop index.

def loop_range(max):
    if max <= loop_range_limit:
	return range(max)
    else:
	raise LoopRangeError, max
--- end ---

Notice that it won't allow the "max" parameter to be bigger than 100. This
prevents users from generating near-infinite amounts of HTML and freezing
your server. You can edit this to any value you like, or even remove it if
you trust all your DTML authors.

Now, create an External method with the following properties:

  id:     loop_range
  title:  Loop Iteration Method
  method: loop_range
  file:   loop_range

To use this method in DTML, try the expr attribute of the #in construct:

--- begin sample DTML ---
<!--#in expr="loop_range(max=50)"-->
<P>Index: <!--#var sequence-item--></P>
<!--#/in-->
--- end ---

> Is there an easy way to do this? Is there *any* way to do it?

Yup. ;-) Zope has tons of power hiding under the hood, and a skilled Python
programmer could make it do almost anything.

One way of doing this would be using an external method:

def MyRange(iMax):
    return range(iMax)

The property bobobase_modification_time gives you the last modification
time. This is not in the docs, I gleaned it from Zope's source (it is used
in amongst other places the document edit screen). This is a good item for
the FAQ.

it's not rendered as list. And when I write doublespaced lines, it's

Subject: [Zope] Bug in sqlvar.py?
Message-ID: <Pine.LNX.4.04.9903132129250.14974-100000@zeus.carolina.rr.com>

Hello, everyone. I'm bustin' ass on my project for the outdoors group and
ran into a problem with the #sqlvar command.

At the top of the file, in the docstring, it says:

    For example, given the tag::

      <!--#sqlvar x type=nb optional>

    if the value of 'x' is::

      Let\'s do it

    then the text inserted is:

      'Let''s do it'

    however, if x is ommitted or an empty string, then the value
    inserted is 'null'.

Either I'm totally off base somewhere, or this is not correct. In one of
my SQL Methods I have a query, with a line:

  <!--#sqlvar address2 type=nb optional-->

And, when I submit the query while leaving address2 blank I get:

  Invalid empty string value for address2

When reading the code, beginning on line 200 there is the else case which
handles values of types other than int or float:

        else:
            v=str(v)
            if not v and t=='nb':
                raise ValueError, (
                    'Invalid empty string value for <em>%s</em>' % name)

            v=md.getitem('sql_quote__',0)(v)
            #if find(v,"\'") >= 0: v=join(split(v,"\'"),"''")
            #v="'%s'" % v

There is absolutely no check for the optional flag in this case as there
are in the cases for int and float. Is this check supposed to be handled
elsewhere in the code, and never make it here, or is this an oversight? I
can patch it to fix the problem quite easily, but if this is not the
preferred way of doing things I'd like to know (to avoid patching it every
time a new Zope comes out.)

I have two address lines, address1 and address2. I just want it to set
address2 to null if the user does not fill it out. Is that too much to
ask? :^)

As I said, if I'm blatantly overlooking something, please let me know. If
not, I'll be happy to submit a patch and/or report this in the collector.

Thanks. Hope you all are having a good weekend!

Message-ID: <199903140517.AAA01144@mail.digiweb.com>

Hello all, 
First let me start by saying I've finally cleared time to play with zope.  
Its coming along nicely but I've hit a snag.  The following snippet in a 
form:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<!--#in qryListStaff -->
<OPTION VALUE="<!--#var user_id-->"><!--#var user_name-->
<!--#/in-->
</SELECT></TD></TR>

using MySQL produces the following HTML:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<OPTION VALUE="2L">Alan Johnston
<OPTION VALUE="1L">Tom Jenkins
</SELECT></TD></TR>

Now unfortunately I believe the L is causing the insert to fail with an 
invalid integer.  I specified user_id as integer unsigned zerofill 
auto_increment.  Does anyone know why the 'L' is being return?

TIA

The L value is caused by a long integer to string conversion. You can get
rid of the L by specifying a C format string, like so:

<!--#var user_id fmt="%u"-->

Ow you're right. But this hasn't changed anything, it still
ask me for the parameters after clicking on submit :-(

In the HTML form, I replaced the action with 
'<form action="add_message/manage_test" method="get">'

where add_message is the Z SQL method. And it adds correctly the
record to my Database, but displays 'This was not a query'.
And, well, I don't think taht's the correct method to add records,
by using the test method :-))

Is there anywhere an example of product adding some records to
a database ?

What's the difference between now and current_date / current_time
I tried all of them, and they give exactly the same result 
(the good date :-)

Message-ID: <199903141232.XAA17000@mbuna.arbhome.com.au>

Short Version of message: ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now 
available from http://www.interlink.com.au/anthony/python/

I'm looking for opinions on the LDAP zope product I've been building.

Right now, LDAP connections work, LDAP Methods work, but there's still 
a bit more to do. Right now, the following is unimplemented:

In ZLDAPconn:
. Anything other than simple_bind(who, passwd) for connecting to the 
    LDAP server
. meaningful doc strings

In ZLDAPMethods:
. Pluggable Brains
. Result Caching
. Limits on the number of results
. Variable interpolation in the filters, and in the base DN
. modify or add queries (only search is supported right now)
. meaningful doc strings :)

Other stuff:
. UserLDAP is not finished yet (or released) - the primary issue is the
    storing of roles and domains. Right now this would have to be some
    non-standard LDAP attribute... but what should it be? It also probably
    needs modify and add added to ZLDAPMethods before being really useful.

Things I'd like comments on:
For ZLDAPconn:
    what other bind methods would you like to see?
For ZLDAPMethods:
    how should add/modify/query be distinguished? Separate methods?

I had planned to get variable interpolation working tonight, but decided I'd
rather get an early night. Probably tomorrow evening, instead. Stuff I hope to
get going in the next day or so: variable interpolation, pluggable brains.

Anyway, ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from 
http://www.interlink.com.au/anthony/python/

It requires David Leonard's ldapmodule, from 
http://www.it.uq.edu.au/personal/leonard/dc-prj/ldapmodule/

It's been tested on Linux 2.2, under Zope 1.10.2 and ZServer. Assuming the
ldapmodule works on other platforms (it's available in source, and also as
a windows .pyd) it should work elsewhere, too.

Try something like:

<form action="add_message_result" method="get">

And then create a DTMLDocument or DTMLMethod called add_message_result
like this:

<!--#var standard_html_header-->

<!--#call "add_message(REQUEST)"-->

<h2>Success!</h2>

<p>
  Your message was added successfully! Thanks!
</p>

<!--#var standard_html_footer-->

The success message will only be shown if the query succeeds, because it
is below the #call statement.

Hope this helps!

thanks guys that was exactly the problem and the above fixed it.  I 
didn't know about the fmt capability.

Anthony: <!--#var user_id fmt="%d"--> works too.

The docs seem to imply that you provide fsdir with a *directory*
ie fsdir=/web/srvs-sol/www.so.cz/ppm

Subject: [Zope] ZAP
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC61@peter.sths.org>

How can I configure ZAP so that all http requests go through the cgi?
Zope is the only thing running through this apache, so I don't want
everything on the site prefixed with Zope/ (or anything else, so no, I
don't just want to know how to change the prefix). This is basically
what is keeping me on ZopeHTTPServer. 

BTW, running ZopeHTTPServer multi-threaded worked well for about 15
minutes. Then suddenly certain pages wouldn't load. I stopped and
restarted the server, but the pages still wouldn't load. I also noticed
that if I stopped Netscape and hit reload, it would cause several new
ZopeHTTPServer instances to appear, and doing so again would continue to
create new instances which never seemed to dissappear. Are these locking
the items they are downloading? The behavior I saw seemed consonant with
it locking the item it was downloading, then failing to recognize the
netscape had disconnected, and thus never removed its lock. When I
restarted it single-threaded, all the pages came up without a problem. I
would really like to move to Zap, but I can't afford at this point to
have the URL of the page change. 

How can I make a Zope pcgi accessible as the root of a Zap install?
Please help.

I've imported a directory using fsimport and it worked for me. I can only
suggest (clutching at straws here) that having '.' in the fsdir attribute
might be throwing it?

Even more clutching here - did you leave the trailing slash off the fsdir
attribute?

In lib/python/StructuredText/StructuredText.py, modify the ul() and ol() methods
as follows:

Change:

  if p: p="<p>%s</p>" % strip(ctag(p))

to

  if p: p="%s" % strip(ctag(p))

I posted a more robust diff to the zope-dev list last night, which allows
replacement of the list-element format string from an ExternalMethod.

Subject: [Zope] Simulating static URLs, end-user session management
Message-ID: <36EC3A7B.53817A8D@erols.com>

Hi.  I am very new to Zope, having spent the last day
(with only about two hours of sleep) excitedly pouring through
the documentation.  I still have a lot to digest, but
there are some questions I did want to ask at this stage:

A)  Are there reasonable ways of arranging to have
    the URLs for some/many Zope generated pages appear, as
    far as the outside world is concerned, to be URLs
    for static HTML pages?  

    The issue is one of indexing by search engine robots.
    I anticipate building a site where most of the 
    content will change fairly slowly, and where there 
    would be a standard set of views of the data which 
    would be essentially static at a logical level.  I 
    really want search engines to index those static 
    views.  (There would likely also be dynamically
    generated views which shouldn't be indexed.)

    So, I think the requirement is that there should be a
    way of getting to pages with a URL like:

	http://www.mydomain.com/here/there/everywhere.html

    as opposed to

	http://www.mydomain.com/here/there/everywhere

    or

	http://www.mydomain.com/here/there?everwhere

    I supect there are a number of ways of tricking Zope
    into accepting URLs in the first form, or perhaps
    into actually generating some static pages which would
    be served up directly by the HTTP server (though
    my quick check of the archives suggests this is an
    unresolved issue). My questions are:

    1) Has anyone already done something like this?

    2) What approaches could you suggest to accomplish
       this?

    3) Is trying to arrange this likely to be a big task
       or a little task (as subjective as that question is)?


B) On another topic entirely, I am wondering about the issue
of tracking sessions of end-users.  (Hmmm... maybe I should
have done more searching in the archives -- this must be
a common issue.)  Various application servers (e.g., for
Java servlets) that I've looked at provide facilities
for maintaining "session" information (not in the sense
of a transaction as used in Zope) about end users.   Typically
this would be done by setting a cookie or by incorporating
a session ID into dynamically generated URLs.  I haven't
noticed anything about this in the Zope documentation.
I'm guessing that perhaps that is because Zope is so
powerful that implementing something like this yourself
is regarded as trivial.  But thinking about it a bit,
I'm not sure what the Zope mindset would be about how
to do this.  Zope sends requests directly to objects.
But in order to manage a session cookie (or whatnot)
you need to add a certain functionality to every (or
most HTTP) requests.  You certainly don't want to have
every object explicitly worry about this.  Is there
a hook that would allow all requests to
pass through some sort of filter that extracts/manages
session information?  Or is there some other standard
solution to this problem?


For what it's worth, I am interested in using Zope
to build my second E-commerce site.   I built the
first site by using Python to generate static pages
from a data structure, combined with lots of JavaScript
and a little Perl CGI.  It worked, but I'm sure there
is a better way.  I was leaning towards a Java servlet
plus templating package solution, until I found Zope.
I've been a Python proponent for a while, but Zope is 
threatening to make my brain explode.  Talk about 
paradigm shifts. 

C) Despite my Python and OO background,
it's not easy to absorb it all at once.  This does
make me somewhat concerned, as my business partner,
who will be a content provider, has no OO experience.
I don't want to produce a system where it will be
hopeless for her (possibly with help from another
developer) to take over if I get hit by a bus.
Thoughts...?

Robert,

I'm only going to address your last point, but it's 
something I feel strongly about.

Let's ignore the technical issues, except to mention
that only you can judge is Zope is appropriate for
your situation.  Fortunately, you have an excellent
opportunity to discover its relative strengths and 
weaknesses.

One of the important secondary issues (some would 
claim the primary) about Open Source is that it
protects your business against the "What happens if
Robert gets hit by a bus?" scenario.  Digital Creations 
is in the business of providing support to organizations 
that use its products.  Heck, in this sense it's even 
superior to key man insurance.

Furthermore, because of DC's courageous decision to 
release Zope as Open Source, not only is your company 
protected against *your* untimely demise, but it's even 
secure against the day Hadar decides to transfer all 
the company assets into hedge funds.

Best regards,

Message-ID: <EF3E7C5CCD67D211A43C006008AE49B8181FF7@JUNG>

Hi All,

As an exercise, I'm trying to get the JobBoard example code given in
http://www.zope.org/Documentation/Reference/ObjectPublishingIntro to work in
Zope (as opposed to Bobo/ZPublisher), and am having some difficulty.

Copying the PeeWee's playhouse example in
http://www.zope.org/Documentation/Reference/ExternalMethods, I placed all
the JobBoard files in zope/lib/python/shared/JobBoard, made an empty
__init__.py file, fixed up the dtml_loc variable, and put a
JobBoard_utils.py file into zope/extensions, which reads as follows:

  "utility to add JobBoard objects to folders"

  def addJobBoard(self,id):
      "Add a playhouse to the current folder"
      if not hasattr(self,id):
          setattr(self,id,JobBoard("Python Jobs"))
          return "JobBoard added with id %s" % id
      else:
          return "id %s already in use" % id

Using Zope's management GUI, I successfully added the addJobBoard function
as an external method, and have successfully called it to create a JobBoard
object called testJobBoard.

However, when I try to view the testJobBoard object, I get an error message
that reads "Sorry, the requested document does not exist."

The addJobBoard function was added as an external method to the root folder,
so my understanding is that the testJobBoard object should also be
accessible from within the root folder (that is that its URL is
"localhost:9673/testJobBoard").

What am I doing wrong here?

Also, what is the proper way to debug this sort of problem?  The output of
the zope process merely mentions a GET request for the given URL, and the
404 response code -- no further detail is given.

Thanks in advance for the help!

-Justin

In looking through my Apache configuration files, I tried to piece
together what changes I made. Here's what I think you need to do.

In httpd.conf, make sure you have these lines (I put them at the end):

Alias / /cgi-bin/Zope.cgi

# Zope configuration maps /Zope/ to the Zope.cgi CGI script
RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

NOTE: In the RewriteRule directive above, the [e=...] stuff should go
directly after the ...Zope.cgi/$1 section, with a space separating them,
e.g. ...Zope.cgi/$1 [e=HTTP...]

You will need to munge the path in the RewriteRule directive, where it
says /home/httpd to be wherever your document root is.

I did this a while back, and have since switched from Apache to ZServer to
test it out, so I haven't used it lately. However, this should work, as I
never changed the config files after I stopped using Apache.

Let me know if you have problems; I'll do what I can to help.

You say "one shouldn't have to use <!--#var "_['foo']"--> instead of
<!--#var foo-->."
However, i find it useful to write:

<!--#if "_['foo'] and _['bar']"-->
<!-- blah -->
<!--#/if-->

instead of:

<!--#if foo--><!--#if bar-->
<!-- blah -->
<!--#/if--><!--#/if-->

Hope that helps...

<!--#var "img.name"--> is the best way to go. It'll insert a IMG tag with
an absolute URL, and if it knows the image width and height, these will be
included in the image tag. Make sure you use the quotes! img.name means:
the attribute 'name' of the object called 'img'.

You can specify the image width and height by hand in the images' property
screen, but if you uploaded a PNG or GIF image, Zope will deduce the width
and height from the image itself. The next Zope release will also support
JPEG image size detection.

Yes, that's what I want. 

Maybe what I'm trying to do is against object-oriented concept? I can
see that images should be kept with the DTML page that calls them. I
just need images to be accessible by a group (role) of "image managers",
but the code that holds it to together should be accessible to an Admin
role only.

There is little reason to avoid naming your objects with the extension
built into the ID, like everywhere.html. You can then simply refer to the
object using that ID, which to a not so smart indexing bot will look like
an HTML file (but it should *really* look at the MIME-type...). The only
problem would be referencing the object, as you have to take precautions to
make sure Python doesn't try to reference the attribute named 'html' on the
object 'everywhere'.

So, as long as you name your DTML Documents that are to be indexed with the
.html extension, everything should go fine.

No, Zope has no Session tracking facilities at this moment. DC is however
working on this. At the moment you will find a 'Session' object in your
Zope distribution, but this is a different concept altogether, and will be
renamed to 'Version' when client session objects appear.

DC can be hired to help out... and as Zope is now Open Source, a growing
number of people can help out.

How about

or 

<!--#if "_.getitem('foo', 1) and _.getitem('bar', 1)"-->

Yep, you got use there.... calling the Image object doesn't generate extra
information like border=0. DC is working on a solution to that, at least, I
think they said so.

For now you will have to write out the IMG tag yourself:

<IMG SRC="<!--#var BASE1-->/img/name" width="<!--#var "img.name.width"-->"
height="<!--#var "img.name.height"-->" border=0>

I assumed that the img Folder object is a direct subobject of the Zope root
object.

I was afraid it would be the case.... I thought I could use Property
somehow (adding text Property named Border with the value 0) but then I
realized that I can't interfere with it, since the rendering takes place
INSIDE while properties are OUTSIDE.

> <IMG SRC="<!--#var BASE1-->/img/name" width="<!--#var "img.name.width"-->"

Looks terrible :-) I think I rather use <img src=img/name border=0> for
the time being.

okay next qustion: I have a image under a folder called "images".
<!--#var "images.somefilename"--> should work - except that the image filename
contains the "." character (eg: "foo.gif") and this gets confused with the dot

So how do I get round this one?

Subject: [Zope] File upload product anywhere?
Message-ID: <v04104401b312cbb2cbde@[128.240.198.13]>

Hi all,
Has anyone written a file upload 'product' that they'd like to share?

My own requirements are that;
the files should (optionally) go to a file system,
I need to be able to change the interface for the system,
the users should be authenticated from an external database,
the files (if held in a file system) should retain their associations 
with folders (for permissions and access),
and I'd like it in blueberry please.

What I'm basically after is the best of both worlds - Zope 
permissions/acquisition etc. with the 'safety net' of a file system 
for large files (and possible batch uploading).

My problem (or one of them) is that there's no way that I'm up to 
speed enough in Zope/Python to start on this...I have a system doing 
the file upload working well in PHP3, but that (obviously) doesn't 
have the permissions/acquisition power of Zope. I guess I could do 
redirects to my PHP3 scripts from within Zope however, but it's 
hardly (ahem) 'elegant'.

any thoughts gratefully accepted.

Tone

The find management screen does give helpful hints. If you want to
implement this kind of searching, you'll have to use the same techniques.
These are however largely undocumented.

The file lib/python/OFS/findResult.dtml should give you a lot of hints on
how to implement a search command. It comes down to calling PrincipiaFind
on a Folder with the right arguments:

obj, obj_ids, obj_metatypes, obj_searchterm, obj_expr, obj_mtime,
obj_mspec, obj_permission, obj_roles, search_sub, REQUEST, result, pre

where

* obj -- base folder to start at

* obj_ids -- (optional) list of object ID's to search

* obj_metatypes -- (optional) list of meta types to search for (if the
string 'all' is in this list, all objects, whatever their meta type will be
included in the results).

* obj_searchterm -- (optional) literal text to search for in the *source*
of DTML Documents and DTML Methods.

* obj_expr -- (optional) DTML expression (as would be used in the expr
attribute of for example the var tag). If this expression returns true
within the context of an object, the object is included in the search
results. You could use this for testing on certain properties, like 'foo=bar'.

* obj_mtime -- (optional) DateTime object or string that can be converted
to a DateTime object, specifying a modification time to compare objects
against. Will on default return objects that have been modified since
obj_mtime.

* obj_mspec -- (optional) When used with obj_mspec, and set to '<',
PrincipiaFind will only return objects which have been last modified before
the date and time specified by obj_mtime.

* obj_permission -- (optional) To be used together with obj_roles. Check if
the roles specified by obj_roles have the obj_permission permission. Only
these objects are included in the results.

* obj_roles -- (optional) List of roles to check for obj_permission access.
See obj_permission.

* search_sub -- (optional) if true, search subobjects recursively.

* REQUEST -- (optional) REQUEST object, used to make sure that
AUTHENTICATED_USER is available for obj_expr expressions.

* result -- a list of objects to be included in the returned results. Used
by the PrincipiaFind method when recursively searching subobjects.
Generally of no use to us humble DTML programmers.

* pre -- prefix the IDs in the returned result list with pre and a slash.
So, when called with pre='foo', and bar is the only object found,
PrincipiaFind will return the list of tuples: [('foo/bar', foo)]. This
argument is used when recursively searching subobjects, where pre is the
relative URL of the object searched.  Generally of no use to us humble DTML
programmers.

The method returns a list of tuples, where the first element of every tuple
is the relative URL of the object found (relative to the starting point),
and the second element is the object itself.

Object name can be different from filename. Thus you name your foo.gif
file just Foo, and that's it.

Zope's object database uses Python's pickle facility, so in general
instances only store their own data, and use whatever version of the class
is available. Classes are not stored in the database. This means that when
you change your class, your instances will be updated.

>Also, is there any problem with the instances failing to work with a newer
>product version?

Yes. And this is not a Zope-specific issue, or even a Python-specific issue.

Anytime you have long-lived instances and change the class, you may run
into problems. Python comes with a couple hooks to help you out. You should
look into __getstate__ and __setstate__ which are documented in the Python
pickle documentation.

Probably the most common type of problem occurs when your new class
definition assumes a new attribute which the old instances don't have. An
easy way to solve this is to provide a class attribute which gives a
reasonable default for this attribute.

For example:

class MyClassV1:
  'Original class'

  def __init__(self):
    self.color='red'


class MyClassV2:
  'Updated class'

  def __init__(self):
    self.color='red'
    self.texture='bumpy'

  def describe(self):
    return 'I am %s and %s' % (self.color, self.texture)

Notice that instances created with MyClassV1 will not have a 'texture'
attribute, so that when the class is updated, old instances will break when
you call the new 'describe' method. A simple fix is to provide a default
class attribute. For example:

class MyClassV2:
  'Backward compatible updated class'
  texture='nondescript'
  ...

Now old instances won't break in the 'describe' method.

Another approach is to test for the attribute and update the instance when
you're going to use it. For example:

  def describe(self):
    if self.texture=='nondescript':
      self.get_texture()
    ...

If 'describe' is the only place where you use 'texture' then you wouldn't
even need to provide a class attribute, and could simply test for the
absence of the attribute.

Finally you might include version numbers in your instances and test for
these, but this seems like overkill. I would suggest sticking to default
class attribute solution for most cases.

Hope this helps, and good luck.

In general, when you have trouble spelling an object's name in a variable
expression because its name is not a legal Python name (e.g.
'sequence-item' or 'foo.gif') then you should use _[] or _.getitem

However in your case you can simply get the sub-object with a plain old
getattr:

<!--#var "_.getattr(images,'foo.gif')"-->

Another possibility is to use the with tag:

<!--#with images-->
<!--#var foo.gif-->
<!--#/with-->

Since these are so ugly, you might consider the simpler manual method of
generating the img tag:

<img src="images/foo.gif">

or else you might consider *not* having a images directory, and keeping
your images in the Folders where they're used. Then you can refer to the
images directly:

<!--#var foo.gif-->

And because of acquisition, foo.gif is accessible to all sub-Folders of the
Folder it is located in, in the same way.

Well, since that's a symlink anyway, I tried to suck directly from
/home/pes/public_html. Still nothing. I even changed that dir to be
world writable.

I tried both.

I'm sure I must be crazy. I summarize what I did:
1. downloaded fsimport.py
2. mkdir /usr/local/zope/Extensions
3. chown nobody:www Extensions
4. chmod /usr/local/zope/Extensions to be rwxr-xr-x
4. copied fsimport.py to /usr/local/zope/Extensions
5. chown nobody:www fsimport.py
6. chmod fsimport.py to be rw-r--r--
7. created External method fsimport inside of ppm
8. put "fsimport" into all 4 fields (Id, Title, Function name, Python
module name)
9. http://www.sol.cz/Zope/ppm/fsimport?fsdir=/home/pes/public_html
10. error "TypeError: read-only buffer, class"

I must have missed something.

	Hi!

	Today I tryed to install Zope-1.10.2 on my FreeBSD-3.1 with
Apache-1.3.4 box.  After succesfully installation I try to connect to
cgi-bin/Zope.cgi/manage and got "file does not exist" error message.  I
look in source code and found that in pcgiConnect() function only
socket() & connect() are present.  But where is bind()?.  When I fix
this problem I found new error message "unable to connect".  In function
pcgiStartProc I found that sigemptyset(&zmask) we use the foollowing:

	while (sigflag == 0)
		sigsuspend(&zmask);

So, after first iteration we have empty signal set and kill(pid,
SIGUSR1) from father will be terminate our process.

If I wrong, please correct me.

Perhaps I'm failing to understand something.
Looking at pages on zope.org and some obviously dynamic pages
on other sites, they all return a MIME-type of "text/html".   Which I
think means that a smart indexing bot should *not* simply look at the 
MIME-type.

As I understand it, most search engine robots try to exclude dynamic
content because of the justifiable fear that once they start exploring
a web of dynamic content they could get lost in an infinite or
near-infinite search space.  I've read that as a result of this, 
search engine robots do things like refuse to index any URL with 
"cgi-bin" in the path, or which do not end in an approved recognized 
file extension.

Do you have a different perception of search engine robot policies/strategies?

Guess I'm going to need to experiment.  I'm a little fuzzy on how this

Are there any projections available re the timing of this?  I'm wondering
about how much effort to spend on ad-hoc interrim measures.

FWIW, in my mind an ideal client session scheme would allow multiple strategies.
In most cases using cookies works out for the best, but I would like to be
able to accommodate anti-cookie zealots as necessary.  On the other hand,
I don't want to clutter URLs with session-id's if I don't need to.  (I suppose
having authenticated users is yet another strategy, and one that Zope currently
seems oriented towards.  Fine if users really want or need to get into your
site or need to perform authorized operations, but not so good if you're trying 
to entice them in.)

While I expect to eventually be working under Unix
(once I can convince my hosting provider to install Zope),
at present I'm trying to use Zope under Windows 98.

The problem is: it's not working.

I'm using the Zope HTTP server, and I can contact the
management system just fine, a prowl around looking
at everything.  But if I try to add an object (whether
it be a DTML Document, a Folder, or an "Item" from
the sample_product package (which I installed), what
happens is:

	I am allowed to fill out the form where
	you enter object creation fields (ID, title, etc.),
	but when I send that form the HTTP server never
	returns.

Any clues as to how to fix this, or debug it, or get any
idea as to what is happening?

It seems to me that Zope is rendering my HTML tag attributs in different

Looking into source produced by Zope, I found
<table CELLSPACING=2 CELLPADDING=2 WIDTH="100%" >
Why is Zope doing this? Maybe there's good reason, but I'd like to know,
because too smart software is sometimes more burden than a help.

Also some attributes are omitted in the rendering process. Property
"width=106 height=106 border=0 align=right hspace=10 vspace=0" ended up
without vspace statement.

OK, here's the situation.

I have a "login" page that I want to list the contents of different
directories depending on the value of the AUTHENTICATED_USER

Each user has a folder under the folder 'user'.

I would like to be able to do (simplified):

<!--#with expr="_.getitem('user'.AUTHENICATED_USER,0)"-->
<!--#in "objectValues()"-->
<!--#with sequence-item-->
<a target="_view" href="user/<!--#var id-->"><!--#var title--></a><br>
<!--#/with-->
<!--#/in-->
<!--#/with-->

However, I get a TypeError on the #with line (and even if I put in the
AUTHENTICATED_USER.id instead of just AUTHENTICATED_USER).

What am I doing wrong here? I've tried a lot of different combinations
of #with and _.getitem and such..

 THANKS

Victor,

I think your problem lies elsewhere.  The client does not
have to bind a local address before calling connect.  The
connect() function automatically assigns an unused port
to the socket.

You will probably find the problem is much more obvious
than a low-level socket bug.  Check your Zope.cgi paths,
permissions, and Apache configuration.

Good luck.

FWIW, after messing around for several hours trying to diagnose
this, the problem mysteriously went away.

(I uninstalled another version of Python and its extensions,
reinstalled them, ran Zope inside Pdb -- and things started
working.  Got out of Pdb, restarted, and things continued
to work.  No clue as to  why things were consistently hanging
before.)

Message-ID: <199903160352.WAA04182@mail.digiweb.com>

Hello folks,
I'm stuck on a problem which I hope some one could help me with.  I 
have a database entry form where the user will enter in information for 
two related tables.  When she submits the form, I want to first post one 
tables information, then call another sql method to get the id generated 
for that post, then take that value and add it to the REQUEST object 
and pass it to the second sql insert for inserting to the second table 
(along with some other parts of the REQUEST object from the form).  

I'm planning on using MySQL that has a special select:
select LAST_INSERT_ID()
to return the last auto-generated id value to get the id.

I know you can add a variable to the REQUEST object via
<!--#call "REQUEST.set('varname', value)"-->
but how to I get the value from the sql method?  The only way I know 
now is via #var tags but you can't nest the DTML.

I hope this makes sense...

This is something Zope can´t influence, it´s part of the way your browser

Could you supply us with some DTML examples of this behaviour? It´s not
something I´ve seen before. Is there any chance your HTML editor is doing this?

I'm wondering; is there a reason why 'range' isn't accessible from DTML
in the '_' namespace? Is the reason as you indicated in your external
method, i.e. that you don't want people to generate vast ranges from
DTML?

The reason if of course merory flooding attacks. A range that asks for a
list of 3 billion items is a wee bit unpolite to the machine.

A way of checking would be:

RANGELIMIT = 1000

def SafeRange(iFirst, *args):
    if not len(args):
        iStart, iEnd, iStep = 0, iFirst, 1
    elif len(args) == 1:
        iStart, iEnd, iStep = iFirst, args[0], 1
    elif len(args) == 2:
        iStart, iEnd, iStep = iFirst, args[0], args[1]
    else:
        raise AttributeError, 'SafeRange() requires 1-3 int arguments'
    
    if iStep == 0: raise ValueError, 'zero step for SafeRange()'
    
    iLen = int((iEnd - iStart) / iStep)
    if iLen < 0: iLen = 0
    
    if iLen >= RANGELIMIT: raise ValueError, 'SafeRange() too large'
    
    return range(iStart, iEnd, iStep)

Maybe this should be part of the _ object. Can someone turn this into a
patch and supply this to DC? I´m a bit short of time right now.

Dear Zopists,

    This is another post to make you aware of a new source of
information for Zope. You can access #zope on the EFNet servers. Their
is an infobot on this channel that could be a great resouce, but it
needs to learn a lot about zope. If you pay a visit to the channel,
query the bot by typing:  /msg wizkid1 help. This will provide more
information on the bot.

I for one think this is a brilliant idea!

I visit the PHP3 channel on EFNET frequently, a real sense of community and
friendship can be built.

I really do hope this comes off, so let's make a go of this eh guys 8^)

Ok, two questions

1. What happened to the Zope web site, it seems to have gone down 
yesterday and still is not operating ?

2. I have downloaded ungziped and untared (Zope-1.10.2-linux2-x86.tgz), 
but the install instructions do not seem complete.  I retrieved the 
INSTALL.TXT file from the doc directory and started to follow them, but 
their doesn't seem to be any 'access' file in this distribution.  What's 
more some of the command line options come up as invalid, like -c,which 
the install program quit on saying it was a invalid option.  The -c 
option doesn't even show up in the --help for the installer.


I was hoping there would be some additional install info on the web site, 
but that's not working.

Try:

select LAST_INSERT_ID() as fred

then grab <!--#var fred-->

If this works then I know what the problem is!  :^)

If you use the database's command line tool and run this SQL statement I
bet it returns a single value (i.e., it doesn't return a table).  The DA
wants to munge and chew on rows in tables.  If think that if you use the
select LAST_INSERT_ID() as fred you'll get a one-row, one-column table
-- this is what Zope wants.

It works from where I'm at. You may want to try
traceroute www.zope.org
(or tracert www.zope.org from Windows)
to see where things are getting hung up.

The access file just needs one line of the format "username:password"
and should be in your zope install directory. Since I was using PCGI
with Zope, all I did was just untar it, make it and then copy Zope.cgi
into my web area...

Try: select LAST_INSERT_ID()+0 to cast it to an int...

Also, check your declaration for LAST_INSERT_ID().. if the above doesn't
work you'll need to either try the patch for ZMySQLDA that was posted a
week or so ago, or do something like: SELECT CONCAT(LAST_INSERT_ID()) to
cast it to a string and then use a nifty Python fn. to convert it to an
integer number. 

It seems the MySQL driver has problems with some datatypes.  There was a
patch posted befure.. I'm curious to know if it'll fix this problem...

Hi!

I'm not using zope, but I'm using ZPublisher and ZServer. I'm coding a

This is in the Zope FAQ, actually, at http://zdp.zope.org/FAQ/external.
At least I think I'd apply to ZPublisher as well?

How do I return an image from an External Method?

Example (for a png image):

    def foo(self, RESPONSE):
        # set the header
        RESPONSE['content-type'] = 'image/png'
        # return the actual image data
        return mkimage()

Another way to set the header information is:

    RESPONSE.setHeader('content-type','image/png')

Martijn

You are right. I wanted to check the frame, which I can't do easily
under Netscape, so I pushed File/Edit Frame, and apparently Netscape
Composer did it, because when I do "Save frame as...", it looks O.K.

Having discovered this, there is no chance I would ever use Composer. I
would be happy to have Zope work as closely as possible with
Dreamweaver, though.

I've been using this.... (Zope example but should work with ZServer)

It was fully expecting to have to mess about with headers to get browsers to
recognise the gif, but broswers seem to know a gif when they get one!

This example returns gifs in a browser when you do ....

http://mysite/renderGif

or even

<IMG src="renderGif">

(I'm fully prepared to admit there may be better ways of doing it) ;)_

Cheers,

Andy.

    def renderGif(self, size=500, counter=1):
        """Draw a pie chart"""
        im = PIL.Image.new('RGB', (size,size))

        # Do GIF manipulation stuff here!

        outFile = cStringIO.StringIO()
        im.save(outFile, 'GIF')

        outFile.seek(0)

Why not use:

select 'id_field_name' from 'table' where 'id_field_name' IS NULL

id_field_name beeing the field with AUTO_INCREMENT set

When using Zope to publish XML documents (using DTML Document objects) I
often write:

  <!--#call expr="REQUEST.setHeader('Content-Type', 'text/xml')-->

Some part of Zope tries to guess the Content-Type otherwise. A lot of this
code is directly shared between Zope and Z Publisher, so you might see
similar behavior.

Eric

Subject: [Zope] Help - need a brainless guide to getting zope running
Message-ID: <36EEBBF1.B7B05990@netscape.com>

Ok, I consider myself pretty technical, but not a UNIX master, and I've
used NT enough to know about services, etc.  But I cannot for the life
of me figure out how to get zope running as a service without manually
starting it from start.bat.


Could someone please post somewhere a "zope for dummies" description of
getting zope running as a service on NT.

Here's what I do:

I downloaded zope 1.10.2
I unzipped and ran the installer.
It works fine to the point where it wants me to choose between running
zope alone or as a service.
I've tried it "both ways" and although I can get zope running fine by
manually starting it from start.bat, and
I make the zope service start automatically, it will not work as a
service!

I dont have any other web server on this machine and dont really care
which server I use. I had assumed that ZopeHTTPServer  would run as the
service, but it doesnt work...

Is there just a minimal way to get zope going on it's own?

I know the ip address etc. of my system, but that doesnt seem to be the
issue.

I wouldnt even mind if in the install you had an option for "install
default web server" so that zope can piggy back on it.

Does it have something to do with setting permissions to the var
directory?

All I'm basically looking for is sort of a recipe style instruction on
how to get it up and running. (With no handwaving like "now configure
your system to run the zope.exe".  Assume I'm a total idiot...

Which I'm not, but I'm still having problems.

No, I don't think that can work. You need another webserver, like Apache
(which you can download from www.apache.org, though of course it has its
own configuration hassles).

Hm..Perhaps ZServer, but that's still not stable. Can it run as a
service in NT?
 
Otherwise I'd recommend Apache; it can do plenty, though there is a
learning curve there.

Here's what I did:

I downloaded zope 1.10.2
I unzipped and ran the installer.
I chose to run zope alone
I created a shortcut to start.bat in C:\WINNT\Profiles\All Users\Start
Menu\Programs\Startup


This will start Zope every time you reboot. Note that it will not get
rid of the annoying MSDOS command prompt window.

I hope this helps

I posted a message last week about running ZServer as a service.  You can
find the message at
http://www.zope.org/pipermail/zope/1999-March/005030.html

I built my Zope from source, so I don't know if this works the same as the
self-installer version, but it should be pretty close.

1. Install Zope 1.10.2, choosing to run standalone.
2. Untar the ZServer distribution in the root Zope directory.
3. Test that it works by running start.py in the ZServer directory.
4. Follow the directions in the message linked-to above.

you get back the correct value in 'last_id'

Well, try something like:

<!--#in lastInsert-->
	<li>The id last inserted is <!--#var new_id-->
<!--#/in-->

where lastInsert is your SQL method

Note this is untested code, so caveat emptor :)

Are the #sqltags documented somewhere? I couldn't find them in the DTML

I found some examples of their use, but nothing definative.

I have no problems reading the source and documenting what I find, I just
don't want to be re-inventing the wheel.

Specifically I'd like to know about #sqlgroup and friends.

Do you really need this? You can put more than one sql commands in a sql
method, you just have to put a <!--#var sql_delimiter --> between them.
You can insert in the two tables with just one method. The
last_insert_id() should be in the values field of the second insert.
Take a look at the code genereated by the sql wizard in the contrib
page.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <36EEE8E7.11F8DBC@erols.com>

Right now my biggest obstacle to setting up a Zope-powered
site could be finding a hosting provider I have confidence
in who is willing to run Zope.  When I asked my first-choice
provider about running Zope, they replied:

> Though it's true that we can install programs that need root
> instlall, it only so when the program is low CPU/mem use and
> non-intrusive. Zope is neither, so to run it you would need to get
> your own dedicated server through us.

A dedicated server is not a viable option for this site at
this point in time.  So, a few questions:

1)  Are the provider's fears justified?  What sort of
    memory footprint, CPU requirements (for a site that
    should have fairly low traffic at first), and other
    impact are Zope likely to have on a hosting provider?

2)  Would anyone care to let me know what their experience
    has been with the two hosting providers (NexusWeb and
    CodeIt Computing) listed as known to host Zope-based
    sites?  (I've been sufficiently badly burned in the past
    by bad hosting providers that I cannot justify signing
    up for a provider without positive recommendations or
    multiple alternatives for backup.)

Hey Paulo, thanks for that tip.  I didn't know about #var sql_delimiter 
and the ability to put more than one sql commands in a sql method.  I 
had wondered about it but the #var sql_delimiter was the key.  With this 
information, no I don't need to insert into the REQUEST object.  But I'm 
still curious <g>.

Unfortunately, putting last_insert_id() directly into the values of the 
second insert did not work.  It works from mysql command line.

<!--#var sql_delimiter -->
INSERT INTO entry_tbl 
	(master_id,submitted_by,staff_id,version,comment)
	VALUES (LAST_INSERT_ID(),
		<!--#sqlvar entry_tbl.submitted_by type=int -->,
		<!--#sqlvar master_tbl.entered_by type=int -->,
		<!--#sqlvar entry_tbl.version type=string optional-->,
		<!--#sqlvar master_tbl.comment type=string optional-->)

It surprised me that it didn't work as I thought it would get sent enmass 
to mysql for processing so I had thought that the DA wouldn't interfer 
with it.

Subject: [Zope] newbie -  permissions on FAQ object
Message-ID: <199903170144.SAA26992@stout.atd.ucar.edu>

I'm trying to configure a ZOPE FAQ object on starship.python.net .

This is Zope v10.10.2 with ZServer 1.0b2 .

I'm baffled by the permissions scheme.  I've created a FAQ under my
ZOPE home:
http://starship.python.net:9673/crew/vanandel

I'd like selected users to add FAQ entries, but only certain trusted 
users to be able to create categories.

Unfortunately, anyone can add a new category, which is not what I want.
The Security Screen for vanandel/NumPy only enables 'view' for 
anonymous, but still an 'anonymous' user can enter the 'Add a category' 
screen, without being challenged.
There are specific permissions shown for various "add-ins" 
like TinyTables on the Security screen,
but not for the FAQ module.  (I'd expect to see permissions for 
FAQAddCategory.)

Also, when I first create a 'FAQ', I can't view it until I create
a 'isCategory' property.  This seems like a bug, since 'isFAQ' is 
already created for me.

A minor question.  I'd obviously like to test ZOPE with various users,
to see what ZOPE allows them to do.  ZOPE uses cookies to give someone 
permission, after they've supplied a password.
Under Unix, I can manually remove a cookie by editing ~/.netscape/cookies.  How do I do this under NT?  Are Netscape cookies in the registry (I hope not!).

Thanks much for your help.

Excellent.

We here at DC (well, I'm out of the office this week, but I'm there
virtualy) have been kicking around an LDAP authentication mechanism,
probably a folderoid, to go against LDAP.  In fact, this was supposed to
be one of my projects when I get back next week.  From the details below
it looks like you have thought this out well, I didn't even consider
making an API of methods like XSQL methods, good idea!

Under the catagory 'result caching' you might want to consider making some
kind of Connection Manager in your LDAP Connection.  A model I've been
kicking around is a CM class that manages Connections and uses a simple 
caching algoritm.  Wrapping all of the API in a class will also help yu 
when you want to break out the LDAP stuff and stick it in shared.  In
this way, it becomes a sort of 'Device Driver' (to use Ken's
terminology) for the entire Zope system.  We're going to be doing this
with the IMAP functionality that NotMail uses.  I'm assuming what
you call an LDAP connection is like a Database Adapter is to ZSQL methods.
Maybe you might want to consider calling these LDAP Adapters.

The etcUserFolder product has a settable property to change the 'default

Don't hurt yourself.  It looks like you got this down pretty good, I'll
proablby be looking into incorporating much of this if not all into Zope,
want to be in charge of zope LDAP?  We can give you an area on the site.

Hey zope freaks:

Okay, I am driving myself crazy, maybe I am just doing something silly
(hopefully).

I am trying to write this recursive SQL result DTML (basically a tree):

<!--#in listCategories-->
  <p>Category <!--#var nm-->
  <blockquote>
  <!--#var recurseCategories-->
  </blockquote>
<!--#/in-->

I have a variable pwd that I want to pass along to recurseCategories..

I tried something like <!--#var recurseCategories(pwd=catID)--> (and in
quotes)

pwd is used in listCategories to get a list of categories in that 'path'

A couple questions:

1. Should I be using a DTML method or a DTML document for something like
this?

2. As I recurse will I lose access to documents in my current folder? I
got a traceback to seemed to indicate that once I was into a certain
depth I couldn't access listCategories.

3. Is there a more Zope-happy way to do this?

Does fsdir parameter of fsimport specify the remote directory (where
Zope is) or local directory (from where I look at Zope)?

OK, so it still does not work for me. If someone on this conference
would look at my mail from Monday, I would be grateful. The idea of
having to put all my images into Zope by hand makes me very sick :-)

Check out the article in Linuxworld:
This is good for ZOPE newbees who wonder what and
why about Python (The underlying language of ZOPE).

http://www.linuxworld.com/linuxworld/expo/lw-python.html

Title: "Python, anyone? "

You may have dismissed Python as just another scripting language beginning
with 'P,' but more and more open source developers are finding Python has
some bite

Summary

At first, the Python scripting language may sound like another version of
Perl, but Robert Richardson highlights the differences that make it useful
in its own right. (1,500 words) By Robert Richardson

Probly I misunderstod your problem.

Anyways I want to say that my suggestion does just what 'select
last_insert_id()' does. namely return the number created in an
auto_increment field during your last insert

Hi,

	I just saw an interesting thread over at
http://www.scripting.com. Here's the direct link to the
article:
http://discuss.userland.com/msgReader$4124

Someone wrote a comparison of Zope and Frontier. Followed up by a
technology demo of getting the two to talk via XML.

Interesting stuff.

My profound apologies.  "select <field_name> from <table_name>  
where <field_name> IS NULL"  does indeed return the same value as 
last_insert_id().  My apologies again.

Hi All,

I'm just uploaded a new Product to the contrib area.

It is a poll product based on Amos's example. It uses PIL to draw
piecharts of the poll results.

I was originally going to include a precompiled PIL with the product, but
the
product swelled to 500k as a result, so instead I've left pointers to where
to get PIL in the product documentation.

I'll send a hypertext screenshot immediately after this message so that
people can decide whether or not they want to go to the effort of
downloading and installing PIL.

Pls note that there are some problems I'm having with getting the GIFs to
update appropriately, so after banging my head against a wall for a while
[in true opensource tradition ;) ] I've decided to throw it open to the
floor to see if anyone can find a workaround.

I've also uploaded a 'fixed' version of the Guestbook example product, which
broke going from Zope1.9 -> Zope1.10.

Enjoy!

Andy.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <000701be709e$ea4cd4c0$642fe18d@jharris.coe.memphis.edu>

I contacted NexusWeb yesterday and they said they would provide a setup for
Zope, but no support.  They were not specific as to the setup.  They did
mention they supported Python.  I was going to write them back to see if
they ran Zserver, or just provided the links to Apache.  They did have msql
and mysql.  The minimum plan to support Zope was the 50MB/$20 a month plan.
The other site was out of my price range ($50/mo).

I just started studying Zope yesterday to use for a project I was planning
to use Visual Basic/ADO/ASP for.  I'm testing on a Win95 machine, but plan
to move testing to a Linux box.

I decided before signing up with a hosting server to wait for Zope 2, which
I've seen a couple of references to.  What's the deal on that?  One place
promised a better integrated web server.  If Zope moves more torward being a
totally self contained server, then I don't want to mess with Apache or IIS.

Subject: [Zope] Newbie questions
Message-ID: <D133051DBC4AD111B90800A0C9694983A61695@natasha.auslabs.lucent.com>

Hi Zopesters,

I'm trying out Zope for the purpose of getting a book catalogue on the web.
So far, I'm extremely impressed with it! Of course, I have some questions.
(For the record, I am running Zope 1.10.2 with Apache 1.3.something on a
MkLinux DR3 box, administered with IE4 on NT).

1. When you edit a DTML document using the Zope management interface and hit
the update button, Zope goes away and tries to parse it to ensure that it's
consistent DTML. If this fails, you are left with no option but the
browser's back button, which, under IE4 anyway, seems to discard the changes
you made to the document. Is there a fix or workaround (besides ctrl-A
ctrl-C before clicking the update button) for this? Us newbies write lots of
bad DTML :)

2. When a folder acquires an index_html document from further up in the
heirarchy, the <!--#var title--> tag refers to the title of the index_html
document, rather than the folder being displayed. How do you write the
index_html document to display the title of the acquired object, rather than
the index_html document itself? (Hope this is clear)

3. Finally, I need some advice about how best to lay out the website.
Basically I'm trying to build a site containing a book catalogue. Here's
what I've got so far:

+ Root
	+ Titles [folder]
		- index_html
		+ OriginSpecies [folder, title: "Origin of the Species",
desc: "blah",
				author: "CharlesDarwin", year: 1854]
			- cover [image]
		+ DiamondAge [folder, title: "The Diamond Age", desc:
"blab",
				author: "NealStephenson", year: 1995]
			- cover [image]
		...
	+ Authors [folder]
		- index_html
		+ CharlesDarwin [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]
		+ NealStephenson [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]

Hope the notation is clear enough. What I want to do is "link" the titles to
their authors and vice versa. So the index_html document for Authors would
display the author, their picture, bio, and a list of titles by them. A
similar arrangement would apply for Titles.

The author property of the title (*) links the title to author, but what's
the best way to link backwards? Similarly, what's the best way to display
the author's information for a title?

All advice appreciated! Thanks.

(*) assuming only one author for now

Subject: [Zope] Newbie install help needed !!!!!
Message-ID: <199903172113.QAA02057@mail.howard.k12.md.us>

Thus far my attempts to install the Zope binary release on a Linux 
machine have been for nothing.  The Install documentation and the Install 
program contradict each other at almost every turn.

The docs say use ./install -u <userid>

but the -u switch is gives a error message, saying it is a invalid switch 
and not supported at all. The install --help, says nothing about a -u 
switch.

The docs say you can specify the cgi directory, with the -c switch, but 
the install program says that is a unsupported feature.

The -s switch in the docs says this is to provide the superuser login and 
password to the install routine, yet the install program say this is used 
to strip tables (perhaps parsing the access file), none of the docs say 
anything more.

I have tried numerous variations, all to no avail.  Perhaps the ZDP 
should have started at the beginning, with usable install instructions, 
instead of with a FAQ.

I must say that the screen shots in the PDF file and those docs are quite 
nice, but thats about it.  Reading the PDF docs, just makes me want to 
get in and try Zope even more.

Is there anyone that could help or give me some pointers ?

Message-ID: <199903180035.QAA28795@christopherrobin.kolo.net>

There seems to be a problem with DTML documents which 
uses more than one <!--#tree--> .. <!--/#tree--> sections.  I'm
seeing a python error when attempting to expand any node of 
the second tree.  I'm going to try and fix this on my own as
a way to familiarize myself with Zope internals but I thought
others on this list might want to be aware of the problem and/or
provide information about their own experience with multiple
trees.

It's on the list. I was originally going to write a simple LDAP auth
object, then thought about it a bit more and realised a generic interface
into LDAP would be more useful, then I can bolt the auth on top.

The way I figure it, I'll support this first. If/when someone needs 
something else, I'll look at supporting that.

Not quite sure what you're getting at here :)

Hm. The LDAP connection already is a class. It's as much a device driver
as the current Database Adaptors.

Good point. Next version, they'll be called that. (I figure I'm allowed
to make changes like this between versions 0.1 and 0.2 :)

That and maybe allowing a mapping for any organizationalRole that 
the users have. More useful for the "lecturer", "student" type
roles.

I've got variable interpolation _mostly_ working. For some reason, though,
it doesn't pick up all the namespaces - I'm probably just not using 
the document templates right. I'm going to add DTML interp. to both the
filters and to the baseDN.

Depends on my supply of round tuits - I might get the pluggable brains
also working shortly. I kinda see how they work now.

Hm - depends if it's easier to get to than my current web site. :)

Some of our applications hang in about 10% when they run. We trussed

Python/thread_cthread.h seems to mention a problem with the Solaris

or the Oracle libraries.

Any ideas or comments ?

Hi Thomas,

>Is there anyone that could help or give me some pointers ?


Yup, those switch options are confusing so I avoid them ;-)

First, the most helpful tool for me in working with Linux is
"git".  This is a nice character based navigation and file
management utility.  Just type git.  It came on my RH Linux
and is installed automatically without your request.  This
program is alot like the DOS Norton Commander that
I started using years ago.

So you get the distribution:
  Zope-1_10_2-linux2-x86.tgz
I use git's F6 key to rename it zope1102.tgz
to ease the long typing.
Move it to a newly created directory (F7)
named perhaps "zope". 

Then in that directory, type: 
    tar -xvzf  zope1102.tgz
A new directory is then created under your
new zope directory named:
  Zope-1_10_2-linux2-x86.tgz/
Go into this directory and type

***This is were you got stuck***

./install

***No switches!!!

Then edit the access file now in
this directory and change the obscure
username and password to your favorites
with F4 key to use "vi"  Press  i to 
insert new user/passwrd -- example:
  zope:gogo
Press escape then :wq  to save.

Then 
  ./start 
to start zope
and maybe later if you EVER want
to stop zope (who would ever WANT
to stop!, 
  ./stop.

BTW,  if you want to test the integrity
of the downloaded zope distro, only change
the t to an x as in:
    tar -xvzf  zope1102.tgz

Enjoy!!!

Ok, unstuck, whoops, stuck again.

I guess I have to do this in little baby steps.  Some sort of initiation 
ritual, I think. ;-)  Now I am getting the error message below even 
though python is clearly in the bin directory under the Zope install 
directory.

"./install: bin/python: No such file or directory"

This is the shell install script:


***
#!/bin/sh

# Get script dir
if [ -n "`echo $0|sed -e 's%[^/]%%'`" ]; then
  PYTHONHOME=`echo $0 | sed -e 's%/[a-z.]*$%%'`
  cd $PYTHONHOME
else
  PYTHONHOME=.
fi

export PYTHONHOME
bin/python inst/product_install.py $*
***

A little different than the PERL I am used to seeing, but I've managed to 
make heads-and-tails of the thing.


- I checked the location of python in the Zope install dir, ok.
- I checked to ensure that the sh shell was in the bin/ dir, ok.


Next up, re-upload the Zope file and check for a corrupted archive.


Any other ideas ?

Hope you don't mind me butting in, but if you just want to check out Zope
very quickly, run the Windows version on 95/98/NT.  It was nothing to
install, and I was playing with Zope two minutes after downloading it.
Python is also a snap to insall on Windows.

Message-ID: <85256738.007567CA.00@mail.cio.treas.gov>



Hi.  Here's the required History:
Cold Fusion almost then found PHP3
and now ZOPE.

I am running a P100 RH5.2 Apache 1.3,
Kernel 2.0.36 and I am pretty sure I have
Zope running:

http://memes.org

But neither my guru or I can get Apache
to dance with Zope -- I am having all
kinds of problems getting the admin page
to work with me and my Login/PW is just
not taking.

My guru cannot even get it going and
suggests using the Python server -- but
I shall not be dashed -- any more info
you need, I will give you a wee bit more:

Want to use MySQL and will be developing
a Writer's site -- for my fun and no profit,
currently at: http://coelaboration.com --
I want to publish Hyperfiction and Hypertext
using Zope as opposed to Perl or flatstatic...

Cheers in advance...

Subject: [Zope] Parsing XML into/out of the database
Message-ID: <199903182236.WAA24270@cheviot.ncl.ac.uk>

Hi all,

I have an application that consists of 140+ XML documents, roughly 100k
bytes each that I want to be able to query (using XSL pattern matching at
present) and output to XML/HTML and RTF format. This will happen in real
time (if at all possible).

At the moment, my XML documents are held as files in a real file system
(sacrilige! :). However, I'd like to get them into the database structure if
at all possible, as I imagine it will make things easier in terms of
searching. For example, the XML file

<?xml version="1.0"?>
<document title="Cell Biology">
<topic title="introduction" id="cb1">
    Cell Biology is a good thing. If it weren't for Cell Biology, you
    wouldn't be around.
</topic>
<topic title="lectures" id="cb2">
    <topic title="lecture" id="cb2" num="1">
    This is lecture 1.
    </topic>
<topic title="lecture" id="cb3" num="2">
    This is lecture 2.
</topic>
<topic title="reading list" id="cb4">
    <topic title="bok" id="cb5">
        A big bok
    </topic>
</topic>
</topic>

Would lend itself to creation in the Zope database really easily (I think).
XML elements (document, topic) and attributes such as id (used to uniquely
identify an element) and title would be properties of the DTML
document/method. So long as the id numbers were properly arranged, it should
be *relatively* (good word that!) simple to recreate the original XML
document. I assume that parsing the XML (in actual fact, the DTML doc/method
would consist of *very little* XML I think, it all being taken care of in
properties) to create HTML would be, again, relatively easy (my own tendency
is to use the 'title' attribute as a class identifier for cascading style
sheets).

My question is, do people think that this idea could fly? I have spent *a
long time* looking at how to get our Word (sorry for saying that!) documents
into a format that means they can be easily put into a database and thereby
benefit from all the good things that means. Several cul-de-sacs and wasted
weekends later, it seems to me that Zope is coming out to be the closest
thing to a solution for my problem...

(I know from off-list discussions that there's a definite 'weirdness' about
how people have been wanting/needing to implement things and then finding
that (a) Zope does it already, (b) there's a product available or (c)
someones working on it... !).

any thoughts, as usual, greatly appreciated.

Message-ID: <Pine.LNX.3.96.990318144553.4537B-100000@taos.kavi.com>

I've been messing around with using direct traveral on the ZSQL methods.
I'm having a problem getting the traveral to work with anything more than
one level of depth, eg:

http://zope.kavi.com/mem/2/comp_admin/contacts/

Where 'mem' is the ZSQL query (that takes one arg), and the arg is '2'.
But it does work in this case:

http://zope.kavi.com/comp_admin/contacts/mem/2/

Is this a restriction on the use of ZSQL direct traveral, or am I doing
something wrong.

If this is a restriction on how you can use direct traversal, I was
wondering why, and if it'd be possible to 'fix' this. If so, I'm willing
to do it and supply a patch, I assume this is functionality comes from
Zope/lib/python/Shared/DC/ZRDB/DA.py, either in the DA.__call__ or in the 
Traverse object. I'll have to mess around with it a bit to figure out
exactely whats going on (but I figured I'd ask about it first).

This is more or less what I did for my original FAQ product (but on a much
smaller scale). I found out XML docs map nicely onto Zope's DB structure.
I think you should give it a try because really it is not much effort to
implement.

Since the FAQ development has moved to zdp.zope.org my site is no longer
needed so I created a guest account with the following authentication
info:

guest
bobo

at URL http://www.gaaros.com:9673

You can visit it and see my approach to the problem. I should also include
the code of the external method that creates the Zope objects. (I believe
a couple of more zopistas asked me for source access so here is your
chance.) I have backed up Zope's DB so you can mess around as much as you
want.

Without seeing your folder hierarchy, I'm not quite sure what's going on.
Frankly, my head feels like it's going to explode when I try and figure
out how your second example even worked. What are comp_admin and contacts?
Folders? Where do they fit in your folder hierarchy?

I have an event calendar, in which I use direct traversal of a ZSQL Method
to display a particular event. My hierarchy is as follows:

+ events [Folder]
  - event_details_html [DTML Method]
  - dbFindEventById [ZSQL Method]

My dbFindEventById method takes on parameter, event_id. To use direct
traversal on my dbFindEventById query, using the event_details_html file
to display the details of the event with event_id of 2 requires the
following URL:

  http://localhost/events/dbFindEventById/event_id/2/event_details_html

At first, I tried:

  http://localhost/events/dbFindEventById/2/event_details_html

which looks very close to your first example, and it did not work. Then I
realized you are required to specify the name of the parameter in the URL
as well, so I added event_id before the 2, and I was off to the races.

I'm sure I've misunderstood your problem somewhere, and if I did, I
apologize for spouting off nonsense. But, I figured this just might help,
since I got tripped up when I first tried to use direct traversal, also.
Better safe than sorry. :^)

Ok, a bit more info...

mem 		ZSQL method (on top level - stands for member company)
+ comp_admin  	folder (company admin)
  + contacts	folder (contact info for that company)

contacts has an index_html which uses information returned from the mem
query (its not how I use it, it won't even display with just #var).

'mem' takes one argument: comp_id (of which 2 is a test case)

Actually, I've found the reverse to be true. When I try:

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

I get this error:

Invalid integer value for comp_id 

Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module
  File lib/python/ZPublisher/Publish.py, line 413, in publish

    (Object: comp_id)
ValueError: (see above)

If I use creosote.spew to output the comp_id value before calling the
query (I made spew an external method on the top level, this has come in
very handy), the value resolves to 'comp_id'.

But when I don't use the comp_id arg (like in the original example, and
spew shows the value to be 2), it works fine as long as the method using
it is the next on the URL.

Actually you are close, but in your example you use it as I said it works.
In your code app can you do something like this (fictional change of your
example):

http://localhost/events/dbFindEventById/ 
	event_id/2/modify_event/edit_event_details_html

(should be all one line)

Make more sense now?

BTW, thanks for the help. :)

Ok, I think I figured out why we have different (opposite) results in
this. I don't think you checked the "Allow direct traversal" checkbox on
the advanced management page for the ZSQL method. If I unchecked it, then
I could traverse like so...

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

After checking it, I could traverse in this way...

http://zope.kavi.com/mem/2/comp_admin/contacts/

Strange... :)

Still doesn't address my original problem thought. I still can't get
access to any of the results of the 'mem/2' query anywhere other than
directly after it (on the url). 

Ie. 

http://zope.kavi.com/mem/2/comp_admin/contacts/index_html 

Doesn't work, but...

http://zope.kavi.com/mem/2/test_html 

Does... 

I'm still digging through the ZSQL code looking for a way to fix this.
I'll let everyone know once I've figured it out.

Ok, here's a thought. What about trying:

  http://zope.kavi.com/comp_admin/contacts/mem/2/index_html

Since the 'mem' ZSQL Method is in your root folder, it will be acquired
by all folders below the root folder. Thus, the URL above should tell
ZPublisher to go to the /comp_admin/contacts folder, then call the
acquired 'mem' ZSQL method, with 2 as an argument, and using index_html to
display the results. (Assuming the parameter name is not required, because
you have checked 'Allow direct traversal', as you described.)

I am curious to know what the 'Allow direct traversal' button does on the
Advanced tab. Can anyone else here comment on that? Frankly, I didn't know
it existed, as I've been able to use direct traversal just fine without
it. It's curious to me that it changes the behavior of the traversal in
the manner you demonstrated. I'm dying to know why. :^)

In this case, I would probably do:

Hey folks,
Boy I'm feeling mighty dumb, but I just now, after maybe 8 hours of

were printed, I finally saw it in the Trinkets Tutorial which I'm sure I read

You'll want to check out the doc/WEBSERVER.txt file under your Zope
directory. Make sure your running a recent enough version of Apache
and have mod_rewrite installed. Then, you need to configure rewrite
rules so that Apache will pass authentication info through to Zope.

All EFNet servers I've tried require me to be running "identd". Is

Simon,
AFAIK, all the EFNet servers require identd.  If you are running ip-masq 
then you need midentd.  You can find it at rpmfind website 
( http://rpmfind.net/RPM )

Sorry, my mistake, there isn't an rpm for midentd... here's the url
ftp://ftp.ox.compsoc.org.uk/pub/users/steve/midentd/
get the midentd-0.1.1.tar.gz  file

Heck, identd is a trivial enough protocol. You can always just
write one in 2 lines of python which just returns "sod off" as the 
username. :)

That EFnet require it is somewhat puzzling.

Subject: [Zope] Zope install help needed: "Premature end of script header"
Message-ID: <v04011701b3179cd6f425@[204.244.68.39]>

I installed the  Zope binary on a linux box, and everything went well. User
authentication worked successfully with Apache using the 'REMOTE USER'
environment variable. Then I tried to get ZMySQLDA to work, but I couldn't
get the Zope Python install to find 'libmysqlclient'. I got a build of
Python 1.5.1 to successfully import MySQL.

So I decided to reinstall Zope from source, so that I could use my own
Python. The source Zope built okay, but when I tried to start Zope through
the web browser I got an "Internal Server Error" message from Apache, the
error log said I had a "Premature end of script header". I've checked
permission on the var dir and user authentication still seems to work fine.
I couldn't figure out why I was getting the error, so I tried re-installing
the binary distribution of Zope. No luck there either, I get the same
"premature end of script header" error message. I've checked the Zope.cgi
file, and it seems o.k.

Does anyone have any idea why Zope.cgi is failing on me? Is there something
I have to do to Apache or Zope if I've removed the Zope folder and then
untarred and re-installed a new Zope?

Don't know if this'll help, but this is what I get when I run Zope.cgi from
the command line:

Many thanks Pavlos - I saw that the Doc effort had moved to zdp.zope.org and
is using structured text, and thought that it was a bit of an opportunity
lost (no disrespect to the Zope Doc Effort of course) as I was amazed to see
that the FAQ system you wrote was XML-based and hence easily extensible.

Thats excellent! - thanks a lot. I'll be snooping around later on once I get
into work - I had looked at XMLConfig almost straight away, but had to put
it to one side whilst I got to grips with Zope  (and Python!) fundamentals.

At least I've got somewhere to start from now...

again many thanks for this,

Also, and this is important!

Don't forget to make sure that the cgi driectory holding Zope.cgi has
ExecCGI turned on.

As I said this is important, later versions of Apache don't turn it on by
default.

The error you get when running Zope.cgi from the command line is a red
herring, ignore it?

It comes about because SCRIPT_NAME is set by the Web Server and as you
aren't running it through such, you will get errors telling you that various
ENVVARS do not exist.

As to your other problem, hmm, it still sounds as if the var dir is not set
correctly, maybe?

Hi everybody,

I am in a FAQish problem. I am using ZopeHTTPServer for setting up a
complex intranet site. However, access control do not seem to work at
all.

Either I can build a public site (which is viewable by everybody), or
I have to use SuperUser passwd to enter in a private site.

I would like to allow user A to see folder X but not folder Y, and so
on. I have created users, assigned roles, but it seems not to work.

BTW, cut & paste do not seem to work at all.

Any suggestions ?

Thanks.

I'm resending this to the zope list, because I didn't get any response
from the zope-dev list.

Hi.

I have made my first Product (a little message wall that people can post
colored messages to), but I am having some trouble with the Security tab.
When I press the tab, I get a Permissions screen that looks as it should,
but when I click the change button (no matter what permissions I change,
if any), I get the following error:

Sorry, an error occurred.

I don't doubt that I am causing this, but since it isn't occuring in my

Thanks for any help you can give.

Subject: [Zope] frames and external method lookups
Message-ID: <9903190931.ZM14151@saab.coinet.com>

I have a DTML Document that references an External Method. This document
is embedded inside another DTML document. If I view this document, then
the page is rendered correctly. If I now take this document and reference
it from a <frame> tag, Zope complains and says it can't find the external
method. What's different here that causing me problems?

Here's some more details, including the traceback:

1. Zope-1.10.2-linux2-x86
2. The innermost DTML docuemnt (lighttablebar) refers to the extermal method
   like this:
	<!--#in expr="looprange(ltblSize)"-->
   'looprange' is my external method and is located in the top level folder
   'ltblSize' is a property of the document that "includes" this document.
   This innermost DTML docuemnt is also located in the top-level folder.
3. The next DTML document (lighttable_frame) includes the previous document
   with a simple #var command (in between some other html stuff):
	<!--#var lighttablebar-->
   This document has a property named 'ltblSize' defined as 6.
   This document lives two folders down from the top-level folder
   I can use the View tab in the manager to see the rendition of this page
   and it looks just fine and there are no complaints about looprange().
4. If I include the previous DTML document in another DTML document that
   is specifying some frames, e.g.:
	<html>
	<head>
	<title>Stock Book</title>
	</head>
	<frameset rows="60%,40%">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/lighttable_frame" name="ltable_win">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/navigate_frame" name="nav_win">
	</frameset>
	</html>
   When I use the View tab to see what this page looks like, I get the two
   frames, but in the lighttable_frame frame, I get an error message about
   looprange being undefined:
---- start of traceback message ----
The specified module, looprange, couldn't be opened.

Traceback (innermost last):

So again, what is happening when the DTML doc is being refered to inside a
frame
that is different than not in a frame (and more to the point, how do I get
around this apparent problem)?

Zope (up to 1.10.x) expects every managed object to have a manage_main
method that provides the default management interface for the object.

You need to rename or create an alias from your default management
method to manage_main.

In Zope 1.10, there will be a new inherited method, manage_workspace, 
which should not be overridden, that picks the first item in you
manage_options as the default management interface.  This gives 
you more flexibility in naming and will allow more dynamic view
management.

Oh, I see.  So the manage_main I see is actually being acquired from the
folder my product instance is installed in?  If so that would explain why
adding things to it actually adds things to it's parent folder.

If I write a manage_main method, will it start magically working, or do I
need to add it to __init__.methods and/or one of the __ac_permissions__
tuples?

I apologize if for the off-topic nature of this post, but felt it was
too important to ignore.

Microsoft has released IE5, which is non-compliant with many of the
standards that Microsoft has helped author. As widespread compliance to
standards is one of the things that will greatly enhance Zopes success
in the marketplace (i.e. WebDAV, XML-RPC), I felt that this issue
deserved to be aired here too.

Greetings!
  Since 1993 I've done my best to show everyone the good on the web and
to
help anyone who wanted it gain the knowledge they needed to create that
good.  Today I'm asking for your help.  I'm not asking not as Glenn
Davis,
CTO of Project Cool, and not as Glenn Davis, cofounder of The Web
Standards
Project.  I'm asking as Glenn Davis, a man who, for the past six years
has
worked to make the web a better place for everyone.
   Recently Microsoft released their 5.0 browser and after all this time
there is still not 100% support for the standards that make web
development
easier.  Standards that Microsoft helped create.
  Below are three simple letters.  Very to the point letters that ask
one
very simple question.  I'm hoping that you'll pick just one of those
letters and use it to ask Microsoft the very simple question within.  If
you would copy just one of those letters into an email and send that
email
to wasp@microsoft.com I would very much appreciate it.  This email
address
is one that Microsoft set up for email about standards.  I'm also asking
that you pass this email along to anyone else who has ever tried to make
a
webpage.
  My sincerest thanks for the help you provide.


Sincerely and simply,
Glenn Davis

Subject: [Zope] Web Application Software
Message-ID: <36F2C006.9D7E89C9@amvalue.com>

I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Ahh yes, Glenn "Master of Self-Promotion" Davis has found a cause with
which to attach his persona.  Glenn got his start at InfiNet, our former
majority owner.  I remember when he shared a 10x10 office with the other
Mac person there.

I love the "I'm not asking as Mr. Mega Big-wig, nor as My. Hyper Star,
I'm asking as a humble guy that singlehandedly saved the web" part.
That paragraph is so pathetic, I can't believe he actually wrote it.

IMO opinion, the only cause he is advancing is himself.  It's a shame,
because browser vendors _do_ need to be beaten into standards compliance
and away from bait-and-switch.

Ok, but what do you think of using the three templated emails? I feel
that they're rather well written, and could be effective. After all,

I believe the current agreement that Digital Creations has reached with
Sam Rushing (the author of Medusa) allows for open-source-style
distribution of ZServer so long as it's used with Zope.  Paul can
probably corret the exact legal situation, but basically DC bought an
unlimited license to give it away ... say thank you :-)

OK, I agree, and I ought to just focus on his words rather than on him.
Public retraction on the personal stuff, BUT I absolutely stand behind
taking offense at the words.  If you're going to lead an offensive based
on principal, make the self-aggrandizement a bit more subtle.

Hmm, didn't turn out to be much of a retraction. :^)

We reached a mutually agreeable arrangement whereby Medusa could become
the core for our object publishing system, under the Zope license.
Definately turned out to be a win-win-win (Sam, DC, and Zope).

Message-ID: <199903200056.RAA27359@stout.atd.ucar.edu>

I see that the bug report and feature request lists are implemented 
using the "Collector".  What's the status of this?

1) Is it shipped with ZOPE 1.10.2?  (I couldn't find it)

2) Is it purchased from Digital Creations?

Thanks much.

AFAIK, ZServer was released (including Medusa) under the same license as
the rest of Zope. Which means that all of it is free software, including
the medusa code it contains.

Nope.

> 2) Is it purchased from Digital Creations?

Yes. At the moment, we are selling Collector. A number of
copies have been sold already. There are a couple of things
to note about a few of the packages that we have been
selling (relatively privately lately):

1) Most have little documentation (read the source Luke :-)

2) Our license specifically reserves the right to give the
software away at some future point (so you need to realize
you are paying to get it now, and shouldn't be annoyed
when/if others get it for free!)

3) Our license specifically prohibits redistribution, or the
creation of derivative works (for distribution)

4) We permit unlimited internal use of the code, including
operating public websites

5) We offer email-based support for 90 days (for 2 contacts
usually)

6) The license is for 5 developers only. If you have more,
you buy more copies

7) Additional support options are available for purchase.

The point of the above isn't to make a lot of money. We're
selling more copies than we anticipated, but hardly enough
to make this our business model. The point of charging is to
cover the inevitable support costs of shipping a product
that has little documentation, but is more technically
advanced to use than the content-oriented Zope general
release.

A secondary benefit is that people who purchase now are
clearly motivated to use the product(s). Therefore, the
support questions tend to be focused around real-world use
of the products, and help us make them more robust for the
inevitable Open Source release (whenever that might be).

So, which products are we currently offering for sale?

1) Collector
2) Z Tables
3) Z Network Client
4) Infoseek DA

In general, pricing is at $1,500 per package. The exception
in the above list is Collector, which is $2,000. The reason?
It makes heavy use of Z Tables, so essentially you are
getting two products for the price on 1.3333 products :-).

Those who wish to discuss this (either to become customers,
or to tell me that we're "off base") should write to me
directly, and _not_ post to the list.

I know that a number of people responded to this already,
including Paul. However, he didn't give as concrete response
as this direct question requests.

The answer is _yes_, Digital Creations most definitely paid
_real money_ to Sam for the right to embed parts of Medusa
in ZServer. However, the intent of the license is to allow
unlimited, free, Open Source(tm) use, within the Zope
environment. If you don't intend to use Zope, then you
should be licensing Medusa separately from Sam Rushing. We
highly recommend it (obviously), and have put our money
where our mouth is.

The reason that this is an important question to answer is
that we are so committed to the Open Source movement, that
not only do we release stuff that we wrote, but when
appropriate, we will invest hard cash to further the
community as well (ZServer being but one example).

<NOTE>I do not know much about btrieve.</NOTE>

<btrieve>
If you can make btrieve a data source you are home free. All you need is the
connector/drivers.

http://www.zope.org/Download/Adapters

Also look into:

http://www.python.org/download/Contributed.html#Database

Typically these modules make there way into zope as they are existing python
modules.
Actually I would gather that Btrieve has a c interface that would make a
great product.

</btrieve>

<dev>

As with all projects .... it depends.

Using attributes is the key to zope. If you take advantage of its ability to
store session variables Zope is far better than other solutions because you
do not need a database to store info during a transaction, you can simply
write it to an attribute in zope thus lowering the # database calls.

I guess the implementation depends on allot of variables that were not
listed in your email.

1. # of concurrent users
2. # of queries and "How databasy is the application? Big Queries?
OnChange?"
3. Specifics on your data model
4. # of tasks required
5. How OO(Object Oriented) are you?

It is a difficult concept to cover but developmental access to ZOPE is
remote by nature. Anything you can do in Zope is accessible anywhere, by
anyone else. Except for installing modules and products, you do not need
machine access ---> Everything is done online and inside of Zope. It is
convenient that way.

Look into the bug collector for the ZOPE site. It allows many levels of
access to the bug database except there is not database just Ztables. It
might be just the ticket.
http://www.zope.org/Collector

Also take a look at the example folder here 
http://www.zope.org/Download/Contrib
Specifically the DTML EXAMPLE FOLDER --> IT WILL GIVE YOU LOTS O' CODE and
HINTS 
</dev>

Just think in OO and Zope will work.

Best of luck.

I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Subject: [Zope] Why do I have to reimport External Methods ?
Message-ID: <99032019551700.01550@alpha>

Hi all !


I am new to Zope, and I have a problem with External Methods.

Everytime I change the implementation of my file in Extensions/test.py I have
to reimport the External Method to see the changes.

What am I doing wrong ? I just want the changes I made to the source
code to be reflected when I reload a page !

I hope someone can explain what I am doing wrong here.

Maik Röder


Some more details:

I have a folder called

VMBI

and an external method

test

in it. Everything works just fine,  the

index_html

file has a call to the external method, which just prints "Hello World!"

 <!--#var test-->

So the following URL

http://localhost:9673/VMBI/test

prints

Hello World !

But when I change the original source code to print for example

Hello Zope !

Then upon reloading the web page 

http://localhost:9673/VMBI/test

there still is printed

Hello World !

What's going on here ?

You don't have to delete and recreate an External Method each time you
change it's file. But you do have to go back to its properties page and
hit the "Edit" button to reload its module (this is actually a nice
feature of python, being able to reload modules at run time).

> What am I doing wrong ? I just want the changes I made to the source

Well, it may be possible to stat the External Methods file each time its
used, and reload it if its changed (you'd have to store its last
modification time somewhere to compare against). This probably isn't done
for performance reasons. Perhaps it could be linked to the BOBO_DEBUG_MODE
environmental variable or something to address this issue.

Is there a similar way to reload code for a Product, or is the
shutdown/restart of Zope necessary?

If I do have to continue the shutdown/restart process, is there any way of
tuning PCGI so that it loads up faster?

Thanks.

But wouldn't that kill the Zope process instead of having it shut itself

A simple way that works for me is, when debugging, have a normal cgi version
postfixed with -c and use that.  This brings me to another thing:  the default
zope distribution doesn't include ZCGI and friends, I assume because Zope
users supposedly have no interest in normal cgi.  I think it should be
included anyway, so that Full Zope is a superset of Only ZP/ZT.  That's more
intuitive, and then you don't have to download both if you want to use both :)
And ZCGI.py is only a small text file, after all.  And perhaps zope users are
interested in ZCGI after all, or does zope make assumptions about running
persistently (can't see how it could, without violating http's statelessness).

And as far as tuning pcgi: you could shorten pcgi_socket():delay
or the 2 second sleep() at the end of pcgiStartProc().  The first one could
probably be pretty safely shortened with the miniscule cost of a chance of a
few extra connect() calls, but the second one should probably stay the same,
although I'm not clear on its purpose (give time for the child to sort itself
out?).

Here's a random question: how come the win32 pcgiConnect uses CONNDELAY
(defined in pcgi.h as 1), while the unix version says int delay=1; ?

See, that's the problem with open source: all sorts of grubby randoms can go
rooting through your code :)

You may season to taste.  The 2 second pause seemed safe enough 
on most tested systems, since we're flying blind.  We've reserved
an extra header byte to designate out-of-band data that could be 
much smarter about how to handle this, eventually.

I don't have the code here, but it's probably trying to
avoid some problem that I encountered when it was 
missing <wink>.

Probably historical flotsam.  The win32 portion of pcgi is
almost a completely separate product and only coexists with
its Unix cousin by virtue of an overabundance of #ifdef 
clauses. 

I've mentioned this before, but it probably won't hurt to 
repeat.  I don't think the win32 version of pcgi as the best 
solution for this sort of thing.  It's mainly there to fill 
out a niche.  Process launch is more expensive under Windows 
than Unix, so the Medusa/ZServer approach is probably more 
sensible in that environment, where good performance is
desired.

Message-ID: <199903221343.IAA17544@gem.lightlink.com>

As a demonstration project to try and get a client to go with Zope, 
I'm converting a newsfeed database that I had originally built using 
Perl.

The object of the game is to pull fresh articles from a Reuters 
server every two hours and put them in a bin. A human editor goes 
through the bin, culls and sorts the articles, edits where 
appropriate.

One article may appear in more than one section of the site. For 
example, an article titled "Zope Is Cool" might appear in the 
Python, Web Development, and Open Source sections. Each 
section has its own contents page.

This is where I get confused. My Perl application simply used the 
filesystem as a database, and generated three separate static 
copies of "Zope Is Cool", placing one in each of  three directories: 
/python, /web_development, and /open_source. I suspect there are 
much better ways to do it in Zope, but how do I organize things?

My naive idea is to make each article a Document, one of whose 
properties is a list (or dictionary) of categories in which it should be 
placed. Generating each section's contents page would then take 
some figuring out, and performance on doing the contents page 
would be a concern.

If there's a better way, I'd certainly appreciate hearing about it.

Correct me if I'm wrong, but the only way I see to do this *inside*
the Zope application is to keep all your articles inside one folder
(pool) and have key documents in your tree structure which 
reference an article in the pool.

I don't know if problems appear when you establish an acyclic
directed graph structure in the object hierarchy itself (I asked
the question myself months ago without an answer).
I see no point why it shouldn't work, but it is not maintained 
by the application.

An interesting fact is that your object's properties vary when
accessed by different paths due to the acquisition structure.
An object inside Zope's database (again, correct me, if...)
doesn't know about its father. It only knows about its sons,
the aq_parent path is constructed on each access.

Would also like to hear more about this...

Check out the FAQ on http://zdp.zope.org  it has some information on how
to use the built-in searching capabilities :-)  It's not perfect, and
needs lots more work, but it's a start.

This application sounds similar to stuff that I (and others on this list are
trying to accomplish).

My immediate term solution is to make multiple copies of the article in the
ZDB. I agree that this is suboptimal.

Paul@DC has mentioned that they are working on a "Catalog" feature that they
would like to integrate with Zope. This feature will be *perfect* for this
application (and many others). Unfortunately, I don't think this is on the
very near term radar scope.

Depending on how far out Catalog is, and when I manage to finish off the
basic necessities for my sites, I was thinking of delving into Zope's btree
stuff and trying to put together some kind of search interface. Right now,
though, I've still got a bunch of work to do before I get to that point.

What a great mailing list! I posted my question, shovelled the 
driveway (Ithaca NY, 8" of heavy wet snow last night), had 
breakfast and an extra cup of coffee, then came back to my desk 
to find 2 good answers. Thanks Stefan and Kevin.

Well, on the one hand I'm pleased to hear that my question wasn't 
trivial. But I'm disappointed to hear that my problem is difficult.

I'm competing against Cold Fusion here, and the problem resolves 
itself pretty easily with linked tables. (At least until I actually try to 
write the code.) So maybe I should just co-opt the competition and 
use ZSQL? But the odb is so nice, I really want to make it work 
that way.

I don't really need for the URLs to look like a directory structure:
instead of /open_source/zopeiscool, it would be okay for the article 
URL to be /zopeiscool?section=open_source. But that still leaves 
the problem of generating a contents page for each section. I 
suppose I could have a script that periodically-or-on-demand walks 
through the articles and generates a fresh static contents page for 
each section. Seems kind of non-zopish, but that might be the 
best way to get decent rendering performance on the contents 
page anyway. (The site is very active.)

Yow!

I suggest you try out your idea first. It sounds simple and
straightforward and performance won't be a problem unless you have too
many entries (but I am only guessing).

> placed. Generating each section's contents page would then take 
> some figuring out,

Assuming you have a folder Entries and folders Python and Zope. An entry
in the entries folder is a DTML doc with a lines property named sections
containing the sections (folder names) where the given entry belongs to.
In the root folder you have a DTML method like: (untested)

<H1><!--# var title--> contents:</H1>
<!--# with "_.namespace(section_title=_['title']"-->
<!--# in Entries-->
<!--# if "section_title in sections"-->
... Do something (ie link to the entry or render the entry etc ...
<!--# /if-->
<!--# /in-->
<!--# /with-->

you can call this method from inside the index_html method in each
section's folder.

This is great, I'm planning on doing exactly this myself. 

Roughly, if I don't want sluggish performance, what would the upper limit
be in regard to number of articles? Are we talking hundreds of articles?
Thousands?

Sorry to post a commercial plug here, but it seems in stride
with my post from this weekend to another question
(Collector).

Basically, Z Tables would be a pretty perfect fit (IMHO). I
realize that you too realize that (sort of), because you
suggested going the ZSQL route. Clearly, there are
similarities. But, Z Tables has already been independently
benchmarked as _kicking a**_ performance-wise, and is also
more closely aligned with the gestalt that you indicated you
liked about the object database.

Just a thought (and a few bucks, of course :-).

Hi Phil,
Sorry I didn't make things clear (maybe I'll update the list?).  Yes I 
solved my problem and feel really dumb.  I didn't realize that the 
traceback is in the error page as a comment.  Once I found that out, I 
saw immediately that the arguments passed in had a couple of extra 
fields that I didn't use (the master and detail tables share some initial 
fields).  I took them out of the sql statement and the form, but I didn't 
remove them from the argument list.  (Just an FYI, the system allows 
you to add additional detail records, the first one is autogenerated from 
the master)

Can the denizens of this group enlighten me about what the 
advantages of Python are, versus Perl? "python" is more likely
to pass unharmed through your spelling checker than "perl".

Unless you do something tricky, I doubt you will be able to get normal
search engines to work with a Zope site, since I belive that most search
engines want to read HTML files from the filesystem for indexing.

>Now I wonder - is there a builtin feature in zope that can fix my problem, or

Right now there is a simple Find mechanism, but it isn't really a robust
search facility. In addition, Zope now includes low-level Python packages
for indexing. So the basic tools are there, but there isn't an easy to use,
out of the box search engine in Zope.

We're working on a much better solution to this problem. We're calling it
Zope Cataloging, and it is currently built with ZTables. I believe that
like ZTables, Zope Cataloging will eventually be free, and become a core
part of Zope. Unfortunately, I do not have a timeline. Sorry. :-(

As long as it's you (i.e. important cause of Zope's open sourcing)
posting commercial plugs on zope@zope.org, I doubt many people would
mind. :)

[ZTables]

Although I'm still a complete ZTables newbie, I've seen ZTables come up
repeatedly when there are similar design problems. This would indeed
seem to indicate ZTables are a good fit. :)

[Apologies if this post is considered off-topic on this list]

You might want to try Webinator, an outstanding search engine available at:

http://www.thunderstone.com/webinator/

It's free to use for up to 10,000 documents. It works by fetching documents
over HTTP (not your file system), so it should work with Zope. However, the
free version requires an Internet connection to check with the license
server, so it might be impractical for an intranet soluition without full
Internet access.


Hope That Helps,

/J

I agree :-). Of course, this is precisely why we intend to
release it (eventually) as Open Source(tm). We truly feel
that the community will benefit, so we will release it. In
the meantime, we're swamped, and prioritizing workload based
on hard currency makes for simple decisions...

I just thought a little more about the approach having a pool
and some proxy objects that refer to the pool.

I think it could be made quite neat when using just the 
following code for the proxies (DTML documents):

    <!--#var "RESPONSE.redirect ('/pool/'+id())"-->

So you just need to put zope_is_cool inside your pool
and add DTML documents with the above code under
the same id to your folder structure wherever you like.
Just check it out.

Two caveats: 
- You have to use DTML documents, not methods, otherwise
  id() refers to the folder's id
- Make sure that zope_is_cool really exists inside your
  pool, or you get an infinite redirection!
  (zope_is_cool is not found in the pool and then sought for
  along the aquisiton path, which refers to zope_is_cool itself,
  which redirects to the pool which ...)

Maybe this could be even generalized to some kind of
"symbolic link" product. Ideas anyone?

An alternate solution could be something like <!--#var "_.getattr(pool,
id)"--> for your "link" methods. I think this would take better advantage of
acquisition. A document could pick up its headers and footers from the
category, instead of the pool. It does seem like someone could create a
"symlink" product pretty easily.

Subject: [Zope] Trying to understand the Scheduler
Message-ID: <36F69DC5.2FBB044@eq.uc.pt>

Zope is great. It's so great that I guess I'm trying to use it for doing
something different from what zope it's expected to do. I want to make
some SQL scripts to access different databases and collect the data in a
new table. That I can do with the following external method that calls
see_data and put_data ZSQLMethods

def get_data(self):
    result = self.see_data()
    self.put_data(value=result._data[0][1])
    return None  

Then I wish to make this kind of data management automatic every hour. I
dug in the sources and I found out the Scheduler class, which I think is
what I need (is it?). But I'm having some trouble using it. This was the
external method I tried (without success).

def eventGetData(self):
    rev = RegularEvent(get_data,(),interval=60)
    self.schedule(rev)
    return(None)      

It seems that RegularEvent is not available. Besides, is schedule
available trough acquisition in the folder? 

Can someone give me some light on this. I don't even know if it's
possible to use the Scheduler with external methods so it would be great
at least to know I'm in the right path.

Thanks

Subject: [Zope] ZTables (Tablula) and SQL databases
Message-ID: <000a01be749d$3ceb65a0$0201a8c0@hawkeye.bob.oc>

Looking for some enlightenment:
<set learning on>

I understand that Ztables was formerly Tabula an
object database.  

If one were starting from scratch without legacy data
would it make sense to use an object database instead
of a relational database?  

If so, is ZTables/Tabula a full, robust database
system that can scale up and exceed the
features of Oracle or SQLxxx databases?

What are the pros/cons of Object vs
Relational databases.

Currently it appears that Ztables/Tabula
is priced at $1,500 but eventually may become
open source.

From recent posts on the list

*"Make site searchable"
*"one 'document' in many 'folders'"

It seems like Ztables would be an Ideal 
solution to these problems.  ie, rather
than the kludge of multiple copies
of the SAME document, ONE copy in
the database.  Also, searching by
key or full text would be possible.

But for further enlightenment, can anyone
point to good examples on the web of the 
use of ZTables/Tabula?

woops, your request to <set learning off>

Do not try to understand the scheduler.  It's not really implemented

By nature anything named "tabula" wouldn't be a pure object database :-)
OODB don't have tables, tables are a relational concept, and I believe
ZTables is a relational database last I checked---b ut then I've never
seen it either, but the implications by Jim/Paul/et. al. are that it is
something along these lines.

Maybe, it all depends on your data, the interdependencies, and what kind
of queries you run, how ad-hoc, and what level of reporting tools you
need.  OODB are mature, but their supporting structure (reporting tools,
modeling tools, and more importantly Zen :-) are quite lacking in my
opinion).

i doubt it, but then, Oracle/et al are not necessarily the right answer
for all problem sets, it's not a one hammer fits all nails solution.

> What are the pros/cons of Object vs
> Relational databases.

Dear gods, there's thousands of papers written on this topic ;-)
References are faster in OODB, ad-hoc is easier in RDB, and there are a
billion other blends... it's also necessasry to understand network
databases in my mind before you approach OODB.

You just can't generalize to this level, it's impossible, and a "quick"
overview of OODB v. Relational would require about 30 pages :-)

Subject: [Zope] passings vars to sql method
Message-ID: <36F6C357.1F277AE3@GestaltTechnology.com>

Zopists,

    I run into a problem. I have a DTML Methos that call an SQL Method.
The SQL method, displayTasks, has two parameters, userID and statusID.

The DTML method does have access to the variables userID and statusID
prior to calling the sql method with a <!--#in--> tag.

The DTML method looks like this:

<!--#var standard_html_header-->
<H2> <!--#var document_title--></H2>
<P><b><!--#in getUsers--><!--#var name--><!--#/in--></b></P>
List of tasks: <form action=displayUser method=post>

<SELECT NAME=statusID>
<!--#in listStatus-->
<OPTION VALUE=<!--#var statusID-->><!--#var keyword-->
<!--#/in-->
</SELECTED>
<input type=hidden name=userID value=<!--#var userID-->>
</form>
<table>
<!--#in displayTasks-->
<tr><td><!--#var taskID--></td><td><!--#var description--></td><!--#var
priority--><td><!--#var </td></tr>
<!--#/in-->
</table>
<!--#var standard_html_footer-->



THE SQL methos look like this:
select *
from task_schedule where
task_schedule.userID = <!--#sqlvar userID type=string--> AND
task_schedule.statusID = <!--#sqlvar statusID type=int-->

--------------------------------------------------
I basically can't run the query because it cannot get a value for userID
or statusID.
How do I pass these vars to the sql method from a dtml method???

Thanks in advance,

Freddy, did you make the variables you are passing to your SQL method
parameters of the SQL method?  If not they won't be looked up in the
request, they will only be searched via acquisition.

This is described in the Z SQL guide where it shows the order of lookup
for SQL method parameters.

Have fun!

I'm still experimenting with ZOPE and the FAQ tool, which uses the 
'tree' display widget.  When I add a category or a FAQ entry, these 
items seem to appear in reverse order of the order I added them.

The FAQ widget index_html DTML contains the line:
<!--#tree sort=isCategory-->

On what basis are the categories sorted?  By name of the object's 
folder?  Is there anyway to get the entries sorted in the order they 
were entered?

Thanks much!

Hi all!

I'm having a problem with running queries containing long numbers.
I found in db.py that the data type NUMBER is converted to an
integer which overflows in my case.

The errors:

Error, oci.error: (1455, 'ORA-01455: converting column overflows integer

from
                if scale==0: type='i'
to
                if scale==0: type='f'

in order to force a float type, but this has no effect, it seems.

I'm sure that I'm misunderstanding something here.
Any pointers to where I can look to fix this would be greatly
appreciated.

Without having yet looked at the source(*) could this be an error
occuring in Oracle itself?

I just noticed the ORA-* which is typically an Oracle error message.

  I have no problems with other applications as long as I stick with
 floats. Notably, Zope on Windows running through ODBC has no
 problems--the values are all converted to python L types. (Hey! maybe
 I should take a look at the ODBC code...) This is what originally led
 me to believe that the problem wasn't with Oracle, but within the OCI
 interface to Zope.  
  I also thought that it also might have something to do with my Linux
 install, but SQL*Net doesn't have problems and Zope works wonderfully
 except for long numbers.

 Environment info:
 Zope 1.10.2
 ZOracleDA 2.0.0
 RedHat Linux 5.2
 Oracle Net8 Client

Subject: [Zope] Questions about DocumentTemplate.
Message-ID: <004c01be74fe$35088aa0$0801a8c0@bobcat>

Ive started playing with DocTemplate for a project, but I will be
using it sans Zope.  I hope this is still the appropriate
place...

I want DocTemplate to expose an object model, and it seems
perfect for the task.  However, Im having trouble using "."
expressions.

Code speaks louder than words, so my code is:
##
class Spam:
	def eggs(self):
		return "Eggs"

spam=Spam()

from DocumentTemplate import *
ss=HTML('Eggs are <!--#var expr="spam.eggs()"-->')
print ss(spam=spam)

ss=String('Eggs are %(spam.eggs)s')
print ss(spam=spam)
##

What Im hoping to do should be quite obvious - I want to refer to
"spam.eggs" in the DTML.

With the HTML example, #var expr="spam.eggs()" is the best I can
get.  It seems ugly to me, and I feel there must be a better way.

Using the String example, I can't make _anything_ work.

Any I missing something?  Is there something I can do so that
String('Eggs are %(spam.eggs)s') does what I want?

Please CC me - Im not on the list (but did peruse the archives
before mailing...)

Thanks,

Mark.

<!--#tree branches="objectValues(['Folder', 'File'])"-->
<!--#var id-->
<!--#/tree--> 

(<!--#tree--> <!--#var id--> <!--#/tree-->) doesn't work either)

This is using Zope 1.10.2 on linux (2.0.35)

All I get is a blank screen - how come??

Here's an alternative that works:

from DocumentTemplate import HTML
class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()
print s.ss(s)

and a second choice:

from DocumentTemplate import HTML

class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()
print s.ss(s)

Thanks for the response.

My problem is that I want a deep object model.  I want the user
to be able to say "spam.eggs" or "pantry.eggs" etc.  Just using
eggs wont do - I really need it qualified.

The solution I came up with was:

class DotWrapper:
	def __init__(self, ob):
		self._obj_ = ob
	def __getattr__(self, attr):
		bits = string.split(attr, '.')
		ob = getattr(self._obj_, bits[0])
		for bit in bits[1:]:
			ob = getattr(ob, bit)
		return ob

Then:
 s=Spam()
 print s.ss(DotWrapper(s))

does pretty-much the right thing...

If your search engine works via http it should work OK with Zope. 
Thunderstone Webinator (thunderstone.com) does this, and there's 
a free version that I think will do up to 10,000 docs. (The 
commercial version costs $700.) There's a command-line switch 
that tells Webinator to go ahead & index URLs that include /cgi-
bin/.

We'll look at overhauling the install documentation for the next

Jeff,

I have cc'ed your question to the list, not to defer it, but to let you
pick the brains of several people who have tried, some successful, some
not, to run zope as a user in a web hosting environment.  None of us
here have tried it so we're not really the ones to ask.  It is true
there is no documentation on Zope with web hosting, perhaps your
discussion will provide information for the Zope Documentation Project,
AKA the Martijn Conspiracy.

As I understand it, the web hosting provider you pick is key to the
whole issue.  If they run the kind of environment that works with Zope,
great.  If they don't (and most probably don't by default) you must
communicate to them clearly what you want.  If they are cooperative and
cool, they will oblige you and join our Zope hosting family.  If you
can't get ahold of them and/or they don't care, your out of luck unless
you go with a Zope friendly provider of which there are two to be found
here.:

Hey Sture,
Check to see if your index_html is a DTML Document.  DTML 
Document has its own namespace and doesn't use the folder's.

If you change DTML Document to a DTML Method then you'll pick up 
the folder's files and folders.

My experience has been that if the hosting company is running Apache (many
do) and if they have mod_rewrite installed (which is probably also pretty
common), it is not *too* difficult to get Zope running in that environment.
However, many hosting companies have policies against creating long running
processes. Zope takes up a few MB of memory, which is considerably more than
an instance of Apache... so many providers are not keen on that kind of
thing. Before putting effort into trying to make Zope work in their
environment, you'll probably want to ask them if they are willing to let you
run a process that will hang out in memory all the time.

CodeIt (one of the Zope hosting companies, http://www.codeit.com) will
actually host Zope for you. You don't need to deal with building and
configuring the package at all.

This typr only affects meta-data seen by some Zope tools.

There is a similar change that needs to be made to *work around*
this problem.  In DCOracle/ociCurs.py, change:

            elif dbtype==2: # Number
                if scale:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

to:

            elif dbtype==2: # Number
                if scale or 1:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

This has the undesirable effect of causing all
numbers to be treated as ints. (This is what oracledb
does) :(  Unfortunately, you can't tell from Oracle column
meta data whether values in a column will fit into Python ints.

The right way to fix this is to implement Oracle's
NUMBER or VARNUM C data types and convert to Python
ints or longs on a case by case basis.

Right, but in this case, it's because DCOracle bound a buffer
that was too small to hold the values.

The <!--#var expr="spam.eggs()"--> is a perfectly valid way to do
it. Another way would be to use the "with" tag:

<!--#with spam-->
  <!--#var eggs-->
<!--#/with-->

Neither is really "more correct" than the other, though the with
construct is probably cleaner in situations where you use many
services of the object:

<!--#with spam-->
  <!--#var eggs-->
  <!--#var method_one-->
  <!--#var method_two-->
  <!--#var method_three-->
<!--#/with-->

Hmm - it appears that the expr support is currently broken
for the python string format syntax. We'll take a look at
that. You can, however, also use the with construct here too:

ss=String('eggs are %(with spam)[ %(eggs)s %(with)]')


Just in case you hadn't found them already, the latest DTML manuals
are on the zope site at: http://www.zope.org/Documentation/Guides/DTML.
They contain some examples that try to demonstrate common DTML idioms.

First, you should use branches_expr, instead of branches. And second, it
depends on what type of DTML object you have this code in. Is this code in
a DTML Method or a DTML Document? If it is a Document, you'll have to
specify the Folder you want the tree to start at::

<!--#tree expr="PARENTS[0]" branches_expr="objectValues(['Folder', 'File'])"-->
  <!--#var id-->
<!--#/tree-->

I think that your approach would work and have the drawbacks you suggest.
You could try it and see if performance is actually a problem.

Here are some other ideas.

First, you can put an object in many folders without creating
multiple copies.  You can't do this from DTML, but you *can*
do it from Python, and therefore, from an external method. 
This may be the simplest approach.

Second, you could come up with some sort of document management
system, based on clever indexing machinery, like ZTables or
on relational databases.  As someone else mentioned, Zope cataloging
with use ZTables to provide collections with advanced searching and
organizaing features.  This is still a work in progress, however.

You're wrong. ;)  There are a numnber of ways to solve this.  I suspect
the simplest is to simply put the same object in multiple folders.

(BTW, this is essentially the same thing as using Unix hard links.)

Sorry you didn't get an answer.  There is no problem with creating 
acyclic or cyclic graph constructors in the, uh, object hierarchy, 
which BTW, need not be a hierarchy. :)

Yes, exactly.  In fact, a better name for aq_parent might
be aq_context.

Hello!

   I've finished large project using pure CGI concept (I used Neale's
html.py). Now I (and my boss) are thinking of switching to Zope, or at
least ZTemplates.

   While playing with Zope and SQL (I am using Postgres, hence ZPygres
Database Adapter), I found that Zope, when loaded into memory by Zope.cgi
(I am using Apache, and need to use in the future) opens a database
connection for every Folder where I created Connection object.
   It is bad, as I have many databases, so Zope eats up memory. Another
problem - what would do Zope if I restart Postgres (so all current
connections break)? Would Zope reestablish connections or just report
error?
   How could I limit number of connections Zope opens? How could I
define a timeout, after which Zope close a connection if there is no
activity between Zope and Postgres? and reestablish connection when
application ask for SQL data?

   With ZTemplates and CGI all these questions has one easy (but not so
nice) answer - there is no constant connection, a connection established on
every CGI invocation.

PS. BTW, I wrote short introduction to Zope in Russian:
http://sun.med.ru/~phd/Russian/Zope/
   Any Russian here to verify my understanding of Zope?

As I understand it, you should just create one Connection object in your 
root folder.  Then all the folders underneath the root folder have access 
to that same Connection object.

Ahh, no need.  Just put one Database Connection object in the top folder
and all the subfolders will "acquire" it.  That is, any SQL Method
defined lower down can use it.

It should re-establish the connection.  If it doesn't then there's a
bug.  This works fine with all the Database Adapters I've used.

There is one connection per Database Connection object.

Hmm, this is quite a hard thing to do, unfortunately.

Of course this means the CPU gets a tremendous beating on every request
and the response time goes down.

   There are connections to different databases. So you said "one
connection to one database"?

   I'll retest, but currently, when I ask ZPygresDA to close connection,
Zope reports "the site has technical difficulties" when I'm trying to
access the application.

Not too long ago I experimented a little with cyclic structures
inside Zope's database. One thing I noticed was, that the copy
support failed with tracebacks like this:

Traceback (innermost last):
  File D:\Programme\zope\koelnzope\lib\python\ZPublisher\Publish.py,
line 877, in publish_module

  File D:\Programme\zope\koelnzope\lib\python\BoboPOS\SimpleDB.py, line

ExportError: Object 184337 references itself

This led me to the conclusion to better leave my hands
off non-hierarchic data structures which differ from those
created by the management interface itself.

	>> Would also like to hear more about this...
	> Like what? :)

More or less simple answers like "this is ok and this
is not", or "you can store any complex Python data
structure inside the DB, but in conjunction with the
management interface, you get the following drawbacks.."

I'm still a quite unclear about the object management
in the database itself and the management layer Zope
adds. 
But maybe I just have to read the docs harder ;-)

If you can use one connection string in Postgres to access multiple
databases, then you just need one Database Connection.  Otherwise,
you'll need one connection per database.  Note that I don't mean per
table -- I don't know much about Postgres and don't know if it organizes
tables into separate databases that are selected with a "use database"
command.

Right, which is the correct behavior, as you had disconnected from the
database.  I thought your question was about restarting _Zope_, so I had
a misunderstanding.

I don't know anything about the Postgres client library and whether it
can reconnect to a server when the server is shutdown.  This definately
isn't a Zope issue though -- the client should handle it.

   No. Connection string include database name, so I need one connection
for every database.

   I meant 3 different situations:

1. I started Potsgres, then started Zope, then restarted Zope - Zope
reestablished connections. It's Ok.

2. I started Potsgres, then started Zope, then restarted Postgres. Zope
does not reestablish connections: This site is currently experiencing
technical difficulties...

3. I started Potsgres, then started Zope, then went to management screen
and explicitly close a connection. Zope does not reestablish connections.

   Situations 2 an3 could be resolved, if I go to management screes, close
and reopen database connections. But it is hard to remember "always restart
Zope if you restart Postgres"...

I'll admit that cyclic data structures are pretty rare, 
so handling them may not be totally correct in every case.

Export of objects partcipating in cycles is potentially, 
uh, confusing, unless the cycles are with objects that are totally
contained within the object being exported, although containment
is pretty hard to check.  I should probably take this error check out.

OK, but I need to know what "this" is.  I don't think
you want me to enumerate all possible "this"s. ;)

> or "you can store any complex Python data
> structure inside the DB,

You can store any complex Python data in the DB subject to:

  - It must be picklable,

  - It must follow the persistence rules:
 
    - Root objects must be "persistent" meaning
      they subclass BoboPOS.Persistent (or implement
      an undocumented interface that BoboPOS.Persistent
      implements, sigh)

    - Subobjects of persistent objects must be "persistent" or
      they must be immutable, or be used immutably, as in:

         def add_member(self, member):
	      members=self.members

              # Oops, mutated a list
              members.append(member)

	      # OK, so pretend it's new and readd it
              self.members=members
         

> but in conjunction with the
> management interface, you get the following drawbacks.."

Basically, the objects need to implement certain
interfaces if they want to play in the management system.
If they don't want to play, they have alot of freedom.

We need to do a much better job of documenting these interfaces.
 
> I'm still a quite unclear about the object management
> in the database itself

The object management at the database level tries to be as 
transparent as possible.  The wish is that you don't have to
think about it.  Basically, if you follow the rules above, 
you should be OK.  

Probably the biggest pitfall in the database is the inability
to get to database objects when their classes can no longer be 
imported, because classes or modules have been moved or deleted
or because errors have been introducted into the module source.
We need to figure out ways to make these problems easier to
diagnose.

I agree that if a remote cause forces a database connection to close, it
should attempt to re-open it... that should be optional of-course, but
should be the default.

Nope, you closed the connection, you have to open it.  This I agree is
the appropriate way to behave.

   Yes, I think Zope must reopen connection.

   May be...

   Well, what about such situation:

4. I started Potsgres, then started Zope, then worked with my application
and Postgres failed (postgres fails sometimes). Postgres returned an error
and closed connection. Zope, I think, should reopen the connection back,
but will it?

Well, actually it should be the job of the DA, not Zope.  It's not
spelled out in a standard anywhere, which probably should be solved.
More documentation probably :/  But hey, someone's gotta know what the
DA is really supposed to do, other than looking at an existing one.

Don't honestly know if it WILL, but it seems reasonable that it should
be capable of trying at the very least.  Again, this is the
responsibility fo the DA, not Zope... that should be made clear.  You're
using a 3rd party DA, so you might want to talk to them about it as
well.

So class Persistent's __setattr__ is basically also the level

Can I expect the undo support to work if I take care of the

Pedro - 
If you need to do periodic tasks, the wisdom of the list says go with a
cron job script attaching to your Zopesite via the ZClient interfaces
(caveat: I know nothing about this - just repeating what I've read here)
Anyone know were to look for info on this elusive ZClient stuff?

Read the source luke :-)  

Actually here's where to find the basics of what you're interested in...

	.../lib/python/ZPublisher/Client.py

This should probably go into the FAQ in the ZDP PDQ ;-)  I remember
seeing a few examples of it, for the the life of me, I can't find them!

Subject: [Zope] Using database-connection from external methods
Message-ID: <19990323200153.C251@RaVER.duck.org>

Hi!

This will hopefulle be my last questions in a while...

Is there some way I can reach/use ZMySQL connection method from within an
external method? Rephrase - I have a connection established within Zope - I
want to call an external method that handles some sql-queries - is this
possible, or should I still have the external method handle it's own
connection?

Can external methods set/send back variables to the calling document/method?

Another question while I'm at it - is the DateTime module in 1.10.2 broke in
some way? (I get an error if I try to make a new property with the date type
set)

Help is much appreciated

The next release of Zope will have a 'utilities' directory
in the distribution that has a load_site.py utility that 
demonstrates use of ZClient (aka ZPublisher.Client).

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

After reading Jim's mail I turned myself to the cron. I had already
written a simple script to http-call a DTMLDocument that calls my
external method. It works, but now that you told me about ZClient I see
I could have saved some time with just a single command

ZClient.py [-u username:password] url [name=value ...]

Thanks guys

Connection strings for MySQL also require you to include the database, but
you can still change databases at runtime via the 'use <database>'
command.

Subject: [Zope] Zope Database in XML
Message-ID: <36F7EF09.6AD34A99@digicool.com>

A side project of mine is to allow conversion to and from
Zope databases (and export files) and XML.  This will allow
people to more easily access their data without Zope and correct
problems, such as moved or renamed software modules, that prevent
data from being unpicklable.

I've completed a first cut at a tool for converting a Zope 
database to XML format. It is provided in the file 'bbb.py'
in a 'utilities' directory that will be included in the 
distribution directory of the next Zope release.

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

To run the tool, use:

  python utilities/bbb.py -rxml var/Data.bbb

For now, the tool provides a way to "get at"
your data without Zope and get a bit more of an idea
of how Zope organizes data in the database.

The file uses a module 'ppml.py' (Python
pickle markup language :) that must by in the
same directory as bbb.py or in the Python path.
ppml.py provides for conversion from Python pickles
to XML.  It will eventually provide conversion
from XML to Python pickles.  Comments from members
of the XML SIG (those who happen to spend time here
too) would be welcome.  I haven't written a formal DTD
for this XML format.  I would like to use a standard Python
XML pickle format, but I'm not sure if such a thing exists 
yet.

I took the approach of conversion to and from Python pickle
format for two reasons:

  - It allows me to do conversion to and from
    database format without actually creating any 
    (application objects).  This is much faster than
    creating actual objects and does not require that
    any application Python modules needed to unpickle 
    objects be around or working.  For example, this allows
    conversion of objects that are not unpicklable.

  - It means that many of the implementation details
    of pickling can be avoided.

Of course, in combination with the Python pickle modules, 
pickling objects to XML is straightforward:

  import pickle, ppml
  print ppml.ToXMLloads(pickle.dumps(myobject))

Enjoy.

Jim

Just have your external method call ZSQLMethods. For instance, I have an
external method which allows the user to upload a file to the database.
The external method reads the file, parses it, and calls a ZSQLMethod to
update the database.

To do this, assuming your ZSQLMethod is in the acquisition heirarchy,
simply call it like you would any other method. If you have a ZSQLMethod
called 'insert_client', which takes the arguments 'name, company, email',
just call it...

self.insert_client(name=client_name,company=company_name,email=client_email)

 
> Can external methods set/send back variables to the calling document/method?

External methods can modify the current REQUEST object that the DTML uses
from name resolution. If you are calling the external method from within
the DTML, just use 'self.REQUEST' to access the current REQUEST object.
Just create/set items on it like it was a dictionary... 

sekf.REQUEST['new_key'] = new_value

If you can access the database directly through this interface(xml/pickle),
couldn't you *potentially* map a network drive to the interface(cifs/nfs).
This could allow you to render data in and out of the database through the
file system interface rather than ftp/http.

Just a thought!

Alternatively your external method can return objects to the calling DTML.
for an external method spammethod you could do omething like:

class A:
	pass


def spammethod(self,n):
	a=[]
	for i in range(n):
		tmp=A()
		tmp.no=i
		a.append(tmp)
	return a

Then in your DTML you can do something like

<!--# in "spammethod(20)" sort=no -->
<!--# var no -->
<!--#/in-->

Ugh.  I thought I had checked it in, but I handn't.
I just checked it in.  Try a cvs update.

I'm not sure what you are getting at here.  You can export and import data to
a file system now, using the Zope database format, which is built on
Python's pickle format.  The XML conversion feature just gets the data into a
slightly more editable form.

One key difference between http/ftp and the file system is that
Zope trusts the file system much more and is willing to get pickles
(binary, XML, whatever) from it.  This is a sort of a security 
feature.  In the future, I'd like to make a variation on the
Python pickler that was easier to configure to be pickier and
safer to use with network supplied pickles.

Ok, I figured out a way to hack around this limitation of traversing an
ZSQLMethod. I whipped up a simple 'pluggable brain' for the ZSQLMethod in
question...

---------------------------------------------------
from Acquisition import Implicit
from Record import Record

class req_store_brain(Implicit):
    """ stores info from sql query in REQUEST """

    def __init__(self):
        new = {}
        for key in self.__record_schema__.keys():
            new[key] = getattr(self,key)
        self.aq_parent.REQUEST.other.update(new)
----------------------------------------------------

This simply sticks the results of the ZSQLMethod in the REQUEST object.
Everything in the heirarchy after this has access to the queries results.

What I am referring to is rendering objects in the ZOPE database to a file
system view. The object database could be managed as a Network Drive(except
that the view would be data in the ZOPE object database). You could through
some translation (xml or other) render the object database to CIFS/NFS.

1. Run applications directly from the ZOPE file system.
2. Modify and Render objects through a regular file explorer or file manager
potentially an external text editor or file editor(word,excel,other).
3. Objects that had no meaning to the file system view would not be
rendered. Attributes to file properties.

This is a feature of 8i that oracle is pushing. The rendering of a database
to a user that does not realize it is a database.

ie.
1. Open a spreadsheet in the Network Drive and see a current version of a
file and its data.
2. Intranet is now a shared drive - depending on your privileges - you see
different objects.

I guess what I am asking is: Can Zope act like a CIFS/NFS file
system(virtual file system) with a layer of translation for converting Zope
Objects to File system objects directly (XML or other)?

If I understand it, this is how the database is rendering objects to HTTP or
now(Zserver)FTP. Why can't you render them as a Network file system?

Any thought?

I've just hit something similar in the mysql client. The mysql client
has a time-out to close the connection with the server. I'm using it in
a test environment where it isn't accessed frequently. The connection is
automatically closed and I have to manually close and open the database
connection.

Has anyone already fixed it? Excuse me if it has already been asked in
the list, but the egroups site isn't working.

You seem to be asking for a hybrid of Zope and Samba ;-)  Seriously, we
have Samba, so one answer would be a filesystem driver for the undelying
OS that talks to the Zope server to get its information. This could be
re-exported as a samba share, or NFS or AFS or Coda or what-have-you. 
I've been musing about it for linux for a little bit - I'm going to try
and convince one of the bright sparks around here to take a crack at it.
For NT hosted Zope, you'd need to write an equivalent filesystem driver
- apparently the the SDK for that is ~$1000.

Oh, and parts of this are already present in the ZServer - it talks FTP,
and there was some discussion of exposing object properties as virtual
docs of some sort. Check the list archives.

Ah.  I think that this is one of the things that WebDAV is going to
accomplish.  For example, IE5 can create an thing that looks like 
that looks like a Windows explorer on a Zope folder.

Ahhhh....

Oracle's approach to this is an add-on to 8i called IFS(Internet File
System). It renders a database to http(woo...woo, Zope does this in its
native functionality). Although, they are working on a renderer for native
file systems. This would enable object methods for making files on the fly.

As Zope already accomplishes this(rendering objects), thus presenting the
view of the oo database is thus a filter. HTTP,FTP,CIFS,NFS,POP,IMAP all are
protocols that speak the requesting clients language. Make Zope the engine
and supply a framework in Zserver to plug in the server renderer.

Samba is a great example. It renders between file systems quite well,
although it is rather a tough and complex animal and very specialized.
Although it would work along the same lines.

Actually, there is a PERL module to simulate file systems already. It could
be good start. Considering that most file viewing on Windows is moving to
HTML, the Network Drive is looking more and more like a simple security
login with a connection that is persistent, rather than actually mapping the
drive.

A distributed (native-CIFS/NFS) file system would change the industry.
Actually it already has (http) through a browser window. I am wondering when
it will occur as seamlessly as not having to be in a browser. If an ORB
existed that could render data to the requesting protocol, it would be a
great product, I think ZOPE could do this through the ZServer architecture.

The Server in this case is the renderer, the ORB is the fulfillment
component and the OO Database is the storage mechanism. The protocol plug-in
is stored in Zserver and renders the appropriate view of the data.

 PROTOCOL |    SERVER    |   ORB   |  OO DATABASE  |

</OS ADD-ON CLIENT> 
   HTTP   |    ZSERVER   |    --- ZOPE ---         |     Client dependencies
   FTP    |    ZSERVER   |    --- ZOPE ---         |     Applications
designed to be client/server!!!

   IMAP   |    ZSERVER   |    --- ZOPE ---         |
   POP    |    ZSERVER   |    --- ZOPE ---         |
</OS ADD-ON CLIENT> 

<OS NATIVE>   
   CIFS   |    ZSERVER   |    --- ZOPE ---         |     No Client
dependencies - Native Applications
   NFS    |    ZSERVER   |    --- ZOPE ---         |     CLIENT/SERVER
functionality yet no dependencies!
</OS NATIVE>                                             OS support is the
dependency!

If the rendering engine were modular, ZOPE would always be first in
delivering support for new protocols and client functionality(DAV
Support!!!), without changing the structure of the underlying database. The
data exchange between the ZSERVER AND ZOPE would have to be managed. "You
wouldn't want to serve a POP client an Excel file unless it is an attachment
just as you wouldn't want to render a query to a FILE SYSTEM accept ones
that have been designated as OK." Get It?

It would save the world a little time and effort if one system could render
data to a diverse set of clients. Rather than making a new server every time
a new client arrives. I could simply build a layer of translation(XML) for a
client and BINGO! New client/server.

At the Native OS level this has the most power. Rendering live data into an
Excel file on the fly is a real world application that would be a huge hit
right now. "I want this months sales report... open Sales.xls  BINGO!!! The
data is there." I would really like to edit html in Dreamweaver as I
regularly do and have it render into Zope. If you had file system level
support every known application could be stored inside of Zope or have
access to the data inside of ZOPE.

Here is the interesting one:

If you can have direct file access you could:

Open a client application out of an oo database that rendered a view of the
database back at you.

(Sounds awfully like an OS!!!)

Just Thoughts.....

[Project Idea] Looking ahead to the future of Linux ...

[ I am on the Digest list, so send responses directly if you
  expect an immediate response. ]

Although I am a new user, I am quickly growing very fond of Zope.  Quite
amazing, multiplatform and all.  The option to use either the built-in DB or
an external one, the built-in web server or an external one.  My entire
company is thinking of standardizing on Zope since we run Solaris, Linux and
NT (along with a few, rogue *BSD variants) on our server-end.

Little and big internal projects aside, I was wondering if Zope could
possibly fill a gap that will come about with Linux shortly.  That gap is
software distribution at the enterprise server to client level.

Linux (and many other OpenSource software and systems) is winning in the
server arena, but the corporate desktop world is staying with NT and the
consumer world is staying 95/98.  While the third will take awhile, the
corporate desktop is something that is attainable in the next few years
(with all the Windows 2000 issues which I do not want to get into).
Microsoft has SMS for NT and even Apple has a better system for MacOS X
Server.  What does Linux have?

First off, most Linux distributions have RPM.  While the format is the same,
the filesystem and other distribution or installation-specific configuration
may differ.  Quite possibly, a Zope-based distributed management system
could be built to serve this purpose.

I guess my main question is if anyone else is trying to forge such a project
togther.  E.g., does the Caldera Open Administriative System (COAS) plan to
solve such software distribution issues?  If not, do any others?  If not,
I'd say it is a BIG DEAL to get such a project underway.  And Zope may be
the perfect fit for the back-end (hence, why I am posting this to this list
instead of a my local LUG).

Just an idea.  Please feel free to pick it apart (short of calling me an
idiot, well maybe you should anyway :-).  I am still learning Python at this
stage (big-time Perl advocate, but Python is definately better for
web-apps).

The field of online software distribution is certainly hot.  Marimba,
the original Java darling, has reinvented themselves in this field:

  http://www.marimba.com/products/products.htm

They are playing, though, in a pretty complicated mission-critical kind
of field.  The requirements are pretty daunting.

One thing I've seen that's pretty interesting in a low-tech kind of way
is rpmfind from rufus.w3.org from a repository.

It's certainly a big deal in that it is an enormous initiative.  Take
some time to jot down what you think the business goals and the
requirements of such a project might be and recruit some volunteers!

Beyond writing an ExternalMethod, is there a good way to catch exceptions?

For example, I have a database application that looks pretty ugly if
someone attempts to add a duplicate key to the database.  Ideally, I'd use
a <!--#try--><!--#/try--> tag to trap exceptions and to provide handlers
for them.

Anyone have any thoughts on this?

Hmm, I found a reference to this in the Collector as something that has

Is anyone working on patches to address this in the near future? I'd be

This is so that I can quote individual included variables into a query string I

Message-ID: <8174B1EE3D2CD21180960000F8056723FCC3CE@telisnt1020.is.tel.co.jp>

 Thanks for the pointer!

 I have to retract what I said in a previous post about not having a
 problem with the ZODBCDA--it has the same problem. I had made a small
 hack of a product for my own study that connected through ODBC and
 that didn't have the problem because I used Python longs. I somehow
 got the two confused...

 This works, but everything gets converted to floats like you said. In
 my case, this is not so much a problem because I use a lot of large
 numbers but doesn't seem practical for general use.
 I found that if, in Buffer.c, I change lines 143 and 144 to

      case 'd':
         return PyLong_FromDouble(self->val.d[ii]);

 I can get the same results as my product--everything is a
 long. Unfortunately, this causes everything to be printed with
 Python's 'L' appended instead of '.0'. Either can be fixed by
 using fmt="%.f" to all of my number fields, but that seems like a 
 lot of extra work (maybe a quick hack to the Z Search Interface
 would do the trick?)

 Plus, what if I really have floats somewhere? Would something like:

      elif dbtype==2: # Number
         if scale:
            buf=Buffer(arraysize,'f')
            dbtype=4
            dbsize=8
         else:
            buf=Buffer(arraysize,'d')
            dbtype=4
            dbsize=8

 in ociCurs.py (lines 123-131) handle this? I haven't tested it yet on
 float fields. It might be better to just leave everything as floats.

Please, stab away!  If you write the try DTML tag, we'll crown you

I'm not sure I understand what you want here, but perhaps interesting
for you is the Trove project. Perhaps it's directed more to larger scale
internet based distribution, though. Another problem is that as far as I
know the project isn't progressing very quickly if at all (perhaps you
can help).

I've even heard mention of ZTrove, which would be a Zope based Trove, if
I understand well. I don't know what the status on that is.

Mind, I don't know a thing about Trove, just giving pointers in the hope
it's useful.

Trove is sketches of code in Python (written by Eric Raymond) and ZTrove
is vaporware, barely prototyped in bobo a few months ago when I was on
the Trove list.  It's unfortunate, since I felt that Trove was a great
idea; the Internet hasn't reached the point of 'we need it now' in order
to get some development behind it.  Personally, I think Sunsite and
RedHat should give us lots of money so we can write it. :)

With Ken and I now in the Zope loop (Ken was one of the original Trove
designers, and I was in on the GUI side of things, pushing what was at
the time Bobo) we could probably bang something out sometime in the far
future.  We'd prefer someone in the community start it up because Paul
and Rob have us booked sometime into the year 2011.

On my Linux box, if fsdir == '/fred/barney', then fred as well as 
barney must be world-readable. If not, you get the error traceback

Confera uses ZTables functions, and these were introduced in Zope 1.10

...just download Zope 1.10.2 and Confera will work just fine.

Confera requires Zope 1.10.2 to run. SearchIndex is a package that is
oncluded in that release.

That's just Unix-style permissions, no?  Can't expect to
access "/fred/barney" if you don't have execute perms on
"/fred".

Subject: [Zope] Counters
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC6F@peter.sths.org>

I remember noticing various comments on the list bemoaning the lack of
some sort of counter. I also remember noticing the objections which were
raised, and why counters weren't feasible. I don't remember reading
these objections, which may be why when I found a need for a counter, I
sat down and wrote one. I now have a working Counter product which
provides a <!--#counter--><!--#/counter--> tag .

It includes the ability to have multiple non-incrementing displays of a
counter, and the optional ability to render the individual digits using
a supplied template, thus allowing graphical counters of whatever sort
you feel like using. The counter uses a long property in the containing
folder, so you can manually set the counter to whatever you want. 

It also provides the optional capacity to have a short 'memory' of
recent IP's, preventing the 'running up' of the counter by scripts or
massive reloading (well, makes it more difficult anyhow). 

The template is supplied with variables which indicate the position of a
given digit in the list (it is wierd, it works from back to front, since
it uses modulus) including whether the particular digit is the first,
etc. 

If someone will supply me with instructions on how to package the
product, and how to upload it, I will be happy to make it available.

Thanks are due to tsarna@endicor.com, on whose product this was based,
and to Jim Fulton and Philip Aylesworth for answering my questions.

Uh, no, I think. chown root /fred, chmod 700 /fred, chmod 711 
/fred/barney. Then anybody can get a listing of barney, but only 
root can see what's in fred. And if I su nobody and run python, 
os.listdir('/fred/barney') works but os.listdir('/fred') gets 'Permission 
Denied'.

CounterTag the same way (I think). Its only 2.24Kb, so I am going to

With regard to the IP checking mechanism. Realize that this reduces the
count for machines behind a masquerading firewall and increases the
count for machines on dynamic IP dialup accounts. 

If anyone is interested in using this counter but wants to prevent a
given IP from incrementing the counter a second time under any
circumstances, it should not be too hard to modify the code to store the
IPs in an SQL table as (I think) Slashdot does. I have no need for this,
and don't intend to code it, but the code, being Python, is, I think,
clear enough to modify.

I'll indicate my appreciation of your contribution by, well, asking for
more! :^)

One of the big objections of the counter kind of object is that the
object database gets bigger on every request.  A good workaround for
this would be to cache writes to the database.

Thus, imagine a counter that:

1) Only wrote to the database after a threshold had passed.  For
instance, only every tenth state change or not until ten minutes had
elapsed since the last write.

2) If the process was nicely shut down, the object would save itself.

3) Had knobs in the management screen that allowed adjusting the
"buffered write" policy.

The benefits:

1) The database wouldn't keep versioning into oblivion.

2) The application wouldn't be slowed by writes on every request.

The drawbacks:

1) If the process exited not nicely, some state changes would be lost.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC72@peter.sths.org>

In the stock Zope 1.10.2 distro, putting a Long in a property causes a
curious error to manifest. When the property page is displayed, the long
is display like 44353L. If the then change any other property and
attempt to save changes, you get a traceback saying that the property
for the long is invalid. You are forced to manually remove the 'L'
before saving changes. 

May I suggest that when the properties are display, if the type is
'long' then the display code
should do something like this:
str(long_value)[:-1]

This would remove the L before it was ever displayed.... Alternatively,
something in the response code needs to be modified to accept an 'L' at
the end of an integer destined for a property whose type is 'L'.

Message-ID: <19990324200904.8613.rocketmail@web204.mail.yahoo.com>

Previously, using Bobo, I created several PickleDictionaries for use on
my website. Regularly, I would pack these databases before ending the
CGI call since they were altered very frequently.

Now, using Zope, I find that I cannot pack them without receiving error
messages telling me I'm attempting to write while the database is in
read-only mode (it appears the Zope threads out the packing). I also
found that Zope caches these databases and issues an error when I
attempt to open them again.

What is the best way to pack and close these databases? How can I query
which db's have been opened? Even if I do keep a mapping of previously
opened db's, how can I find out if Zope is closing them. 

Any help is appreciated. 

Thanks,
Kevin

Hey.. this isn't bad.. in writing even :)

Okay, I have a prototype of this written.. basically you can do the
following:

<!--#try-->
foo
bnar
<!--#var sgkjgdsjksdg-->

<!--#except-->

The exception was <!--#var err-->

<!--#/try-->

So, if an error occurs inside the first block, the second block is
rendered with err substituted for the variable (in this case it prints
exceptions.KeyError

This is pretty basic stuff, so I'm looking for ideas on where to take
this.

Anyone have more ideas?

This is just a guess, but I doubt it.  You'd probably need a DOS port of
Python, which would eliminate all the networking code.  This is just me,
I don't have a 3.1 box, but... you're welcome to try :-)

I've gotten a lot of reports about a broken link to the ephemeral,
much-referenced "BoboPOS3a1" technical docs.  I promised myself I
wouldn't update the link unless I updated Jim's doc to Zope-ify it.

Thus:

1) The official name of the database is "ZODB", the Z Object Database.

2) The News on the site has a link to the ZODB3 Technical Documentation.
This is a very well written, circa October document from Jim Fulton that
describes the architecture of the next version of the database (i.e.
Zope2).  It's quite nice -- contains UML diagrams, API discussions, etc.

3) The broken links have been updated.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC79@peter.sths.org>

Ok, having read the newly available ZODB manual, it seems that I should
override __setstate__ and call the old __setstate__, passing it a
dictionary containing only those attributes I wish to be persistent.
Then I don't have to call my __setstate__... it will be called
automatically by the system. This should have the effect of making any
item not mentioned in my dictionary non-persistent, which will allow me
to accomplish Paul's goal. Now, the BIG question... This ZODB manual is
for ZODB3, which we don't yet have! So is this still the correct and
workable technique for accomplishing this?

Thanks again... and please everyone, don't use the old Counter product,
since these tags are going to conflict horribly, and this new product
should be much better for the DB, according to Paul, if I can make it
work.

For .deb there is the official package manager (www.debian.org), but
there's a 'Debian Package Finder', which is already complete python :-)
On http://badger.alaska.net/debian/finder.cgi
That may be easier to convert to Zope.

Well - darn if you aren't right.  Only the
immediate parent directory of the item to
be opened/listed matters (so far as execture
permissions), not the grandparents and up.

Seems strange to me -- but seems you're right.

Maybe something like this for the version 2.3 :-)

Subject: [Zope] New Counter Product

Here is the updated Counter Product. This contains two classes, one
which provides a visible Counter Product which can be added as an
object, and which has Security options, and a new tag which provides a
means of accessing the Counter Product. Note: the tag should be able to
access ANY object which possesses a getCount() and a incrementCount(md)
where md==_. So an SQLCounter Product which stores its numbers in an SQL
database should be able to use the same tag structure. Since it passes
md into the incrementCount, the Product is free to store as much or as
little of the REQUEST as it chooses. My product stores only the IP
address, and only under proper conditions.

The tag structure is described in the CounterTag.py source file, and
examples are given.

I hope this is useful to someone.

Okay after I opened my big mouth I had to deliver. :)

NOTE: THIS IS NOT ALPHA ALPHA CODE.. BEWARE

Here's an example of what this is:

<!--#try-->
 This is the try block
 <!--#raise type="bar"-->
  You suck
 <!--#/raise-->
<!--#except-->
 There was an exception! Yay!
 <p>It was <!--#var errname-->
 <p>It has this to say: <!--#var errmsg-->
<!--#/try-->

I incorporated a suggestion that except should handle <!--#except
NameError--> to specify the error to trap.  Also, <!--#except--> will
handle any errors by default.

This is packaged as a product, is this the best way to distribute this??

Grab it from:
ftp://ftp.spyderlab.com:/pub/zope/Try-0.1.0.tar.gz

Since I've only been programming Python on and off, hopefully I didn't
make any major assumptions about doing things a certain way.  Please let
me know if I have.

There is another IRC channel on the EFNET network, #zope.

It is 'protected' by an eggdrop bot so there should be little chance of the
channel disappearing.

It is manned, at the moment at least by, Phil Harris, Fredy Villa and
others.

There is also a knowledge bot, zoppy, which can answer rudimentary questions
about Zope/Apache/Python.

We have a small but growing community, join us.

See ya there

If I have a URL like '/manny/moe/jack', I know that from within the 
top-level object, I can retrieve the object 'jack' as 'manny.moe.jack'.

But if the context is jack, how do I specify the top level so I can 
talk about manny?

Hello,
I want to use a computed field to convert the broken umlauts from a

translate(ARTBEZ,maketrans('”�„','öüä'))

But when i test the expression i get the following result:

Test Computed Field
Expression: translate(ARTBEZ,maketrans('”�„','öüä'))
Computed Field Error: (, )

Does anybody have a solution for my problem?

The top-level object is the 'app' attribute in the Main
module.  Note, however, that this will change in
ZODB3.

  import Main
  Main.app.manny

From an external method, self is the object the Externel Method is called
from. If you have REQUEST passed in, you can access PARENTS[0], which is
the top object. From there you can traverse down the hierarchy.

Subject: [Zope] Configuration of Apache-authenticated Zope on Apache 1.2.6
Message-ID: <Pine.GSO.4.02.9903250839420.15119-100000@isis.visi.com>

Okay, I understand that the "fall-through" authentication to Zope will not
work with rewrite rules when Apache 1.2.6 is used.  Unfortunately the
project I'm starting is being done for a shop that refuses to upgrade to
1.2.6.

I have Zope working just fine with Apache authentication; for the needs of
my project, this method of authentication works just fine.  However, I
need to know how to properly set up Zope to run in a virtual domain
"container", _and_ to only authenticate parts of the object hierarchy at
one time.

The idea is that we have a website

docs.foobar.net

that is a virtual domain on an Apache 1.2.6 server, and we need to
authenticate any requests underneath

docs.foobar.net/manage

so that the world can see the pages but only people in our list can
manage.

Another simultaneous difficulty is finding the proper way to make this
virtual domain automatically start in folder "docs" of Zope's object
hierarchy.  I've used an Alias to translate docs.foobar.net to
docs.foobar.net/cgi-bin/Zope.cgi/docs , and it works fine, but I don't
have proper Zen mystical knowledge of Zope to understand the _proper_ ways
of doing these things, if such ways exist.

I have done a scan of Email archives and most of the documentation on the
Zope site, but either I'm dumb as nails or just don't know the proper
magic keywords to get the information I need.

Zope looks great, I've resisted learning a new language but a killer app
makes it worthwhile.

I am not sure how to classify it. The original complaint was about the
Properties page. 

My problem seems to be with values returned from MySQL - even regular
integers get an L tacked on the end (This didn't happen with zope 1.9).

So is this two seperate collector entries?

Where does mine go - Zope, ZSQL Methods, or ZMySQLDA? What do others
think? Has this shown up with other SQL DBMSes?

One thing I just thought of: I moved my ZMySQLDA over from 1.9 to 1.10.2
without recompiling it. That is when I noticed this problem. Whould
something have  changed in the python header files or something that
would have made it advisable to recompile ZMySQLDA? What did others do?

Phil.

Message-ID: <613145F79272D211914B0020AFF6401907BBB6@gandalf.digicool.com>

Greetings,

For those of you interested in the NotMail project we have some
announcements.

First, Digital Creations has officialy adopted NotMail as one of it's
products.

Second, in an attempt to make the products at least *sound* more mature
:), we are changing the name.

Third, in the last two weeks I have been working pretty hevily on
NotMail and it has changed significantly.

Therefore:

NotMail is, for the interum, called The Artist Formerly Known as NotMail
(TAFKAN).  We still call it NotMail, but that's just our code word.

TAFKAN was once a product, but now it's just a bunch of dtml methods.
The actuall imap functionality that TAFKAN needs has been abstracted
into another product called IMAPAdapter.

IMAPAdapter is very early alpha software.  It has several known bugs,
and Linus knows how many unknown ones.  Your millage may vary.  It may
light your computer on fire.  It might delete all your mail and crash
your imap server.  It might send insults in your general direction.  You
get the point.

IMAPAdapter is, in Zopespeak, a 'user database'.  Other examples of user
databases are User Folder, UserDb Folders, and etcUserFolders.
IMAPAdapter walks, swims, and quacks (to quote Jim) like any other type
of user database.  The simplest example of using IMAPAdapter is:

Create an empty folder without an 'acl_users'

Add an IMAPAdapter (it will automagicly call itself 'acl_users'),
telling it where to find it's imap server, what default roles to assign
to users, and other misc stuff.

Create a DTML Method called index_html containing the following DTML:

    <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

Going to this file will prompt you for a username and password (assuming
you've correctly set the permissions and roles).  The username and
password you enter here must be a valid IMAP login for your imap server.
It is *not* necessary to add a Zope user to Zope, IMAPAdapter will try
your uid:pwd pair against the IMAP server and validate/deny you based on
the sucess or failure of making an IMAP connection.

What you will see when you look at this DTML Method is a pretty #tree
breakdown of all your imap namespaces, folders and subfolders.

IMAPAdapter, like all other user databases, contains a validate() method
that Zope calls to authenticate a user.  This method returns an imapUser
object (which inherits BasicUser, like most other Zope user objects).
This user object is what AUTHENTICATED_USER refers to.  imapUser exposes
the imap API to the DTML programmer.  The API is currently a very rough
draft, and there are several functions that were in TAFKAN that are
missing in IMAPAdapter (like the folder management stuff to
add/edit/delete imap folders)  At the moment, IMAPAdapter is pretty much
read-only on your 'imap space'.

Voila!

IMAPAdapter is available in public CVS.

Web CVS access will be here soon!  (yippee!)

I have a Zope sandbox which I would like to use to play with new features 
as they become available.   Unfortunately, for the past several days my 
sandbox server has been broken because ExtensionClass/ComputedAttribute.c 
is missing.

Is it missing on purpose?  If so, is there  a way I can work around it?

Message-ID: <Pine.LNX.3.96.990325153317.2349F-100000@taos.kavi.com>

Hello,

I'm having a strange problem with logged in users getting to anonymous
areas of the site. Here's an simplified example to explain...

Two directories off the /
/private
/public

/private allows no access to "Anonymous User", requiring a login.

There are no usernames in /acl_users. All the user info for logging into
/private is kept in /private/acl_users. 

/public has no acl_users folder.

If you start up netscape, you can get to /public without any problems. But
once you've logged into /private, you can't get back to /public without
getting an unauthorized error...

  You are not authorized to access this resource. Username and password
  are not correct. 

  Traceback (innermost last):
    File lib/python/ZPublisher/Publish.py, line 877, in publish_module
    File lib/python/ZPublisher/Publish.py, line 531, in publish
      (Info: /MCExam)
    File lib/python/ZPublisher/Publish.py, line 297, in unauthorized
  Unauthorized: (see above)

Any tips about how to fix this. Note that the login info has to stay in
/private/acl_users (they can't be moved to /acl_users).

Thanks,

Ok, the problem was that I had the roles defined on the top level folder
and the users defined in the subfolder. By moving the roles into the
subfolder, the problem went away.

I suspect a matter of resolving.  Probably be a two step procedure, 1) try
to match the error by string exactly, otherwise 2) evaluate each handler 
in turn and see if the exception isa class.

I have fixed this in 0.1.1 of the Product which is now available from the
same directory as the original.  I've also made some other additional
fixes relating to the default error handler.

Here's the file:

Message-ID: <19990326081646.A10042@box.dust.za.net>

Hi!

A day or two since last question - now two new ones...

Q1

My site is organized so that one folder keeps several other files and folders (containing files and folders and so on). Something like:

Top [Folder]
	F1 [Folder]
	F2 [Folder]
		F2-file1
		F2-file2
		F2-folder1 [Folder]
		F2-folder2 [Folder]
			F2-folder2-file

...

index_html (Top) has <A HREF="F2">F2</A>
index_html (F2) has <A HREF="F2-folder1">F21</A> and <A HREF="Top">Top</A>

Starting at URL: localhost/Top is fine and following links to F2 and from there on to F2-folder is correct (URL beeing localhost/Tope/F2/F2-folder1), but if I, when in F2, press the link to 'Top' something strange? happens: I get to Top all rigth, but the URL is now localhost/Top/F2/Top (Top beeing appended to the URL)

What am I dooing wrong?

Q2

Recently I got help on using the #tree tag, and apparantly everything worked all rigth, but ...

I get the tree-view, can expand the tree pressing either foldernames or the '+' button - fine. But If I press the '+' button I'm not able top directly access the files appearing (404 error, file not found), I have to enter the folder first before I can get the file. This seems strange and I want to know if theres a solution to this.

Heres my #tree href part:

<A HREF="<!--#var URL1-->/<!--#var id-->"><!--#var id--></A>

Help is much appreciated

You're URL is a relative one. The browser sees 'Top', and requests the
object Top with the current Base URL, which is localhost/Top/F2/. And
because of Aquisition, Top.F2.Top exists.... And so will
Top.F2.Top.F2.Top.F2.... which can get you into a nice caching problem.

Your URL should include the realitve path to the subfolder. the var
tree-item-url gives you the URL to the current object, relative to the base
object.

Your code should read (untested):
<A HREF="<!--#var URL1-->/<!--#var tree-item-url-->"><!--#var id--></A>

Or words to that effect..

Computed attribute is not an includeable library, or something along those

Hello.

   Continuing the subject...
   Next question. If Zope opens one connection to a database, how does Zope
manage concurrency?
   Currently, when two CGIs run in parallel, every CGI opens its own
connection to the database, lock neccessary tables, and Postgres manage
concurrency very good (even detecting deadlocks). Next Postgres version
(6,5) will have Multi-version Concurrency Control. But all this is for
different sessions. Zope opens only one session. Is it a problem with
concurrency?

Hi,

This is (I think) an unusual question on this thread, but I want to ask it.

We are at the start of making an intranet, which will contain a database of
procedures (how to handle some examinations etc). We want to make it able
that people can query this database and get the information they want on
there web-browser.

A day ago, we were confinced that PostgresSql with PHP3 (www.PHP3.org)
would be the solution to this problem. This on a RedHat Linux 5.2 system
with Apache as
web-server. But now we've seen Zope. I'm wondering..., can Zope do the same
things as PHP3? Or is this a complete different application? How stand Zope
and PHP3 next to each other?

I believe PHP3 is a scripting language... I'm wondering : is Zope also only
a scripting language? Or is it more? Is the scripting language (=Python?)
more powerfull then Zope)

Are there people, using PHP3 next to Zope? 

ps. Has Zope the capability to easely make these scripts? I mean not
text-based , but in a certain IDE or RAD application?

Please, say in some simple words what Zope is and for what it can be
used... I've read the web-page. But since I'm a stupid person in this field
of webservers I can't understand what they are explaining.

Thanks in advance.

Kind regards, Tom.

Subject: [Zope] Limitations of just using External Methods ?
Message-ID: <3.0.5.32.19990326185538.0093de20@mail.skinnyhippo.com>

Hi zoppelgangers,

I have several applications built 100% with python CGI
scripts that I'd like to run on Zope. The reason for 
this are :
a) For the better performance (I was worried about
   the scalability of CGI for high-availability and
   knew I had to move to FastCGI or the equivalent)
b) I really really like the way Zope takes care of
   the CGI variable handling (ie. declaring the 
   HTML form fields as arguments in the python method).

However, I don't really want to use DTML at all.
The reasons is that I find it much harder to read 
than pure Python. This is just a personal aesthetic 
thing and no criticism of Zope at all (full kudos to
Digicool on an excellent application). It's just
coding aesthetic : I like it all kept in Python, 
like servlets in java (as opposed to CFML, ASP etc).

So, I've put all of my CGI scripts in a newly-created
extensions directory and registered them via the 
Zope web-manager. It was, as the documentation says,
incredibly simple and it seems to work for simple
methods. (I'll declare my own packages later).

Now, if I just use External Methods like this (using my
own ex-CGI Python scripts to query databases, IMAP etc),
am I missing out on any of Zope's main benefits ? 
In particular, the cache management ?  
Would I have to turn my stuff into  a Zope Product to 
get these benefits ? (I've not had too much joy with
the Product stuff yet)

Message-ID: <000501be777e$83130900$147800a0@pc-pi0>

Hello,

I'm confused with external methods. Please help.

I want an external method to access its context (for the
purpose of acquisition, etc.). So I write:

def myExtMethod(self):
    pass

Within myExtMethod, I should be able to:
- write self.REQUEST to access the current REQUEST object (I
need to be able to modify the current REQUEST object with
self.REQUEST.set(...))
- or for example self.myzsqlmethod() to call a zsql method object,
right???

Let's suppose that myExtMethod is:

def myExtMethod(self):
    l=[]
    for i in self.l:
        l.append(i+1)
    self.REQUEST.set('l', l)

Now, how can I call this method from DTML?

<!--#var myExtMethod-->
<!--#var "myExtMethod()"-->
<!--#var "myExtMethod(this())"-->

All don't work. I end up in a traceback. "read only class, buffer"

Any hints?

Zope manages concurrency by being single-threaded... so only one query at a
time, on ANY connection...

Hi Jepthe,
First, if you want to acces the REQUEST object, you need 
to declare it as a formal parameter:

def myExtMethod(self, REQUEST): ...

REQUEST is then passed automatically by Zope's internal
magic, which looks up formal parameter names and matches
them to arguments from HTML forms, HTTP Headers, etc.

The "read only class, buffer" traceback is due to a very 
annoying bug in ExternalMethod.py and screws up any 
other error messages in external methods.

I can't remember exactly if it was in line 254 or 256 in
ExternalMethod.py, but here's the code I use to fix it:

ExternalMethod.py, from line 254

                if type(error_type) is type('') and lower(error_type) in
('redirect',):
                    raise error_type, error_value, tb
                if (type(error_value) is type('') and
                    regex.search('[a-zA-Z]>', error_value) > 0):
                    error_message=error_value
                else:
                    error_message=''

With that you should get better error messages.

Regards,
Stefan

PS:
	<!--#var myExtMethod-->
	<!--#var "myExtMethod()"-->
should be both OK

Tom,

There are probably other guys here that can give you a better comparison
between zope and php3. I never used php3 but I used ASP (the microsoft
stuff), which is similar (though worst than php3 :-).

With Zope you get a server markup language (called DTML) which you can
mix with HTML. This concept makes it even easier to program than mixing
a scripting language with HTML like php3 and asp do. From what you said
I guess you will just need this kind of programming... so Zope will be a
better choice than php3.

But with Zope you also get *the best* scripting language available:
Python. You can add logic to your application by writing external
methods or products. This kind of extension is much more powerful than
php3, although maybe a bit more complex.

Zope also has a great IDE for managing your site through the web. 

Although I cannot tell you which one is better, if you give Zope a run
try and, ... if my instinct is correct, you will want no other thing.

hope it helps,

pedro

I've used PHP3 since it was PHP/FI and done lots of work in it. It's 
database integration is excellent and the ability to include PHP3 
code into an HTML document and have it 'executed' is really neat (I 
think CGI's are ugly, whereas code in the delivered doc itself is 
elegant - my opinion, YMMV). I've run PHP on Solaris and Linux, and 
used a lot of the contributed code.

Since I found out about Zope, I've desubscribed myself from the PHP 
lists and been focussing on Zope almost entirely. I posted a message 
a while ago 'Tough Questions about Zope' and got some excellent 
answers, for more details I'd check it out in the archives.

PHP3 is a scripting language, and is relatively easy to get started 
in. I may get a 16-ton weight dropped on me (in joke) but I think 
that if you're used to scripting languages already, you may get your 
application up and running faster in PHP3, as Zope scripting ('DTML') 
requires a bit of a mind-flip.

However, once your application gets more complex, I think you'll find 
that Zope will start to pull ahead of PHP3 and eventually pull very 
far ahead. The list of things that Zope provides 'out-of-the-box', 
which are very difficult to do in PHP3 is pretty long; access 
permissions (at varying levels) at a per-directory and per-'object' 
level, editing of web pages online, *undo* - yes, undo!, and versions 
are the things that come to mind initially. There are many others. 
Obviously, there are some things in PHP3 that are a bit 'unusual' in 
Zope too (setting variables for instance! :)

The scripting language of Zope is Python - I've bought several Python 
books (personal rec: Internet Programming in Python by Watters, van 
Rossum and Ahlstrom - top geezers in the Python world) and have found 
it to be quite a beautiful language. You can't install Python 
programs 'directly' into your DTML document, but 'External Methods' 
seem quite easy to write. Once you become familiar with 'Products' 
and what *they* can do, your jaw *will* drop.

> Are there people, using PHP3 next to Zope?

This is a question I asked. The upshot is that it's pretty difficult 
to do in seemless way with current implementations of Apache (ie more 
or less impossible) but that a later version will do that.


> ps. Has Zope the capability to easely make these scripts? I mean not
> text-based , but in a certain IDE or RAD application?

I would say, yes. I would suggest reading the FAQ, then the 
documentation, reading the documentation again (especially the DTML 
and ZSQL documents), read it once more and then if you do decide to 
try Zope over PHP3, have a go at your application. I think that it's 
highly likely that you will be able to get by with just some DTML and 
a database connection.

I'm not knocking the documentation here - the DigiCool guys (and 
gals?) have relatively recently embraced the open-source concept and 
seem to be doing 10 things at once.

I don't think you're stupid at all! :) There are some new and unusual 
concepts in Zope that many people will not be familiar with 
(particularly if you're coming from a 'traditional' web-publishing 
environment).

If it helps, I've been in contact with several other people, both 
here in the UK and elsewhere who are *extremely* excited about what 
Zope is and what it can do.

> Thanks in advance.
> Kind regards, Tom.

You're welcome - I got a lot of help starting out, just trying to 
pass it along... :)

Maybe It's self.l that causes the error. It's hard to understand what
you want, but I feel it should be

   for i in l

Maybe I can help you with this. The traceback you get is probably the
standard error raise in ExternalMethods. To debug external methods I use
try/except/raise code blocks and when I get an exception I return it to
the screen. Something like this

def mymethod(self):
    try:
	mycode
    except:
	import sys
	return sys.exc_type, sys.exc_value
    
    return something

Not yet. ZServer is multithreaded, but Zope itself isn't. This is because
the BoboPOS (cuurent version 2) doesn't support concurrent access. The all
new ZODB 3 will support this, and then Zope can (will?) become
multithreaded as well.

   So I have some time before I'll see problems with concurrent access to

Subject: [Zope] external methods
Message-ID: <000401be778a$e630c2a0$147800a0@pc-pi0>

Ok, I'm dumb.
After some digging, I found that the problem lies in
the expression 'self.l'

'self.' gives access to the object hierarchy, not the variables
namespace.

So, I solved my problem by writing 'self.REQUEST['l']'
instead of 'self.l'

Also, I think that this should be clearly documented.
Apparently, the only way to acess variables namespaces
in external methods is through self.REQUEST
This confuses a 'normal' python user whose variable
namespace is usually accessed through self.

Can someone confirm (or infirm?) this?

I believe that you can just ask for it in your function signature:

def my_method(self,l):
  return l + ' is cool!'

In your external method l is a local variable. You can access it by simply
referencing it. something like

def spammethod:
	l=[]
	for i in [1,2]:
		l.append(i)
	return l

It can do the same thing, and more.  This isn't a hack on PHP3, but Zope
has many more components and widgets out of the box.  It's also object
oriented, which helps when your components scales, or when you want your
application to suddenly be stitched into four other application six
months from now that you didn't forsee.

>Or is this a complete different application? 

PHP has it's niche.  Tony 'tone' McDonald mentioned that he thought code
inside HTML is elegant, and it is, but it's even more elegent when that
code is for the layout of your user interface only.  Mixing application
code with HTML, or worse yet, making your entire HTML document one huge
script, is not so elegent.

Zope is an Application written in a scripting language (Python) that is
based on several components also written in Python and C.  One of the
components of Zope is Document Templates (DTML) which is also a
scripting language.  It's a bit complex, much more so than PHP's
underlying system.  Tony also mentioned that PHPs database itegration is
excellent, and I'd like to add that Zope's is also top notch.  A
particular nice thing about Zope is it's database abstraction layer,
what we call Database Adapters.  You can write program for any SQL
server and just change the DA when you change databases.  Or your app
could use two databases transparently; the DTML programmer wouldn't need
to know which database is being queried, it would just be a case of
calling the write SQL methods.

This also give some compartmentalization.  Your Python expert writes
your external methods, your SQL expert manages DAs and writes ZSQL
Methods, and your DTML/user interface expert uses all of these methods
to layout the application.

Comming soon.  The problem is (rumor has it) that Apache sends Zopes
output directly back to the browser, not giving it a change to run
through any other handlers, like the PHP one.

There is a web based interface.  The (IMO) ultimate programmer interface
is emacs, which can use Zope with FTP (if your using ZServer).

Whew.

Zope is a web application platform.  It is a framework for writing
applications over the web.  It is more than this, because it supports
more protocols than HTTP, but for your purposes you can call it a web
app platform.

Zope provides you with a standard set of services that your application
can build on.  Services include DTML, trasparent persistence of your
data, interface to databases, a management interface for developing and
managing your application, and a whole slew of out of the box objects
for you to use (like documents, files, methods, DAs, mail transport,
etc...)

Many people have mentioned Python in responses to your question.  Python
is an incredible language, but I think the application you described can
be done easily in Zope with no Python at all.  All you need is DTML,
some ZSQL Methods, and a good design and your done.

These 'benefits' you feel you might be missing out on you might not
need.  One of Zope's best features is the fact that you can just use the
components you want.  In fact, it sounds like you may just need
ZPublisher by itself.  If you go to our site and look at the Components
section you'll see where you can download it. ZPublisher is just the ORB
part of Zope, it traverses your python module and calls your methods
based on the URL.

Now, you can still USE Zope with these application you write.  Even if
you write a pure ZPublisher application, you can then plug that
application right into Zope with the External Objects product available
in the contributed area.

Subject: [Zope] installing Zope
Message-ID: <3.0.1.32.19990326200338.009363e0@poirot>

Hi,

Thanks to all the reply I got for my question PHP3 or Zope.

I'm wanting to give it a try, but ....

I've RedHat 5.2 installed with running Apache

I'm trying to install Zope, but am expiering some problems :

I've downloaded the binary and installed it into 

 /usr/local/dc/Zope-1.10.2

installed it with ./install -sAdmin:Admin

the var directory of Zope is permissioned for nobody (done by Zope)

As in the manual, Zope created access with Admin:Admin, but it says login
with Zope:Admin

copied the Zope.cgi to the directory /home/httpd/cgi-bin

I want to use it with Apache so I had something to change in the conf file
of Apache... Apache has 3 conf files. At the moment it is written in all 3
of the files (because none of them work!).

This is the piece of script I've written : (from WEBSERVER.txt)

#Zope configuration maps /Zopz/ to the Zope.cgi CGI script

RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP-CGI-AUTHORIZATION:%1, t=application/x-httpd-cgi,l)]

When trying to browse to http://localhost/cgi-bin/manage I get the password
dialog... I enter Admin , Admin and am refused (same with Zope, Admin) ....

What am I doing wrong?????

--------------------------------------

Now try to use ZopeHTTPServer

I can't find anywhere the file serve.sh

BUT I tried to start it with start

then going to webbrowser http://localhost:9673/manage

I get a message of DNS problem etc...

So not even a question of password...

----------------


Can somebody tell me what I've done wrong? I want to get it to work with
Apache... What do I've to do?

Thanks in advance,

Tom.

Hi,

I noticed that if you're browsing two different Zope sites using the
same Netscape, the management tree on the second one is incorrectly
displayed (the COLSPAN is increased by two).

Has anyone noticed this before?

regards,
Nuno

Ok, I've updated the package to remove the bug that killed it after the
first shutdown/cache loss. The _v_ technique certainly served to prevent
the saving of the variable, so when the system came back up, before I
use the _v_ variable I was testing it to make sure it was higher than
the stored value. I added a test to make certain that it exists... Is
there a way to register a function (or some __func__) that gets called
the the instance is reloaded?

It seems fairly stable now, so I'm calling this 1.0. 

Please send bug reports to shawh@sths.org.

BTW, has anyone actually tested this other than me? 
I thought from the comments I had read on the list that there were a
fair number of people who were perturbed at the lack of a counter in
Zope. Was I wrong? Am I flogging a dead horse here?

Subject: [Zope] Method icons
Message-ID: <36FBFDF1.23E9F89A@digicool.com>

Hi all.  Here's a minor issue I'd like to get some opinions on.

  There are some ideas in Zope that cross 
  object types in Zope, like folders, methods, and
  content.  We reinforce the idea of folders
  by giving folders icons derived from folder
  icons.  I'd like to do the same thing for 
  methods.

  The basic idea is that there should be
  some basic icon that indicates that something is
  a method.

  It should be possible to decorate the icon to 
  indicate a particular type of method, such as adding
  angle brackets for DTML or adding a table grid
  for SQL, or OO (or glasses ;) for Python.

  Note that one complication is that the image 
  should fit in a 16x16 icon.

I've put some ideas at:

  http://www.zope.org/methodIcons

I'm curious what folks think of these and whether
anyone has any better ideas.

Jim

   I need a short informative description on Zope. Something like "Zope is

   What is contact e-mail? I wrote zope@zope.org. Shouldn't it be

Subject: [Zope] Automatically creating instances for each user?
Message-ID: <36FE35BD.AEBBC507@dougiamas.com>

Hi,

I'm new to Zope, but I'm eagerly learning it.  I like the
paradigm - it seems to fit the way I think.

This is my first post here.  I've hit a snag, and I'm hoping
someone more experienced can point me in the best direction.

I'm developing an application that needs user-modifiable pages.
I already have a Zope form where the user can edit text properties
of an object, and another page that displays those properties as HTML.

My problem is, I want each authenticated user to be editing their 
own instance of this object, and I also want the URL to be the 
same for each user.

eg  fred sees http://host/mypage as fred's editable page
    mary sees http://host/mypage as mary's editable page

What is the best approach I should take to achieve this in DTML?

Cheers,
Martin

Yes, the documentation is a bit unclear about this.

You'll need a Database Connection String like this: 
"webdb joe password".

"webdb joe password" should work if the database is running on the same
machine.

Message-ID: <3.0.1.32.19990329102524.0097e170@poirot>

Hi all,

Well, now I don't understand it anymore....

Just back from the weekend (where on Friday I had these installation problems)

Now went to the Zope directory and what did I saw? The 'Start' and 'Stop'. 
I wrote ./Start and then surfed to the correct address and it works!

Why did'nt it worked on Friday? The whole weekend searching for a solution
and then it appears it isn't needed... (almost)

But, still I would like to work with Apache... Why? Because I've heard it's
the best in web-servers... (I don't know it's through, but I believe it) Or
is the comming ZServer better?

Now, I believe I have to recompile apache again to make it ready for Zope,
isn't it? I thought I only had to put it in one of the configuration files,
but instead you've to write that script in the ./configure file.

Kind Regards, Tom.

to install an external driver. 

Is it so that I've to recompile Zope? This means that I've to download the

Because when I need to recompile, I've do download also all the correct

Thanks in advance.

   You need to install and compile ZPygres Database Adapter and add it as
described in ZPygresDA docs. You don't need to recompile Zope.

AUTHENTICATED_USER.getUserName() returns the name of the current user. You
could use this in the DTML of mypage to select the object you are working on.

Hi all,

I'm using Zope 1.10 with IIS 4.0 on an NT box.  All is working well, I just
have one small query which is slightly off topic, maybe.

The URL for Zope is 'http://localhost/scripts/z.exe' and I would like it to
be 'http://localhost/z/', I know that with Apache I could do a rewrite and
this works great with Apache, but does anyone know how I would do something
similar with IIS.

TIA

Nope,

With that definition, my_method expect to be called with the arguments
set, eg <!--#var "my_method('Zope')"--> to display "Zope is cool".

However, I want to get the variable l from the namespace. (application
variables made with REQUEST.set, Folder or document properties, etc.)
The question was: is self.REQUEST the only way to access the
variable namespace? And the only way to *modify* the variable namespace
from external methods (with self.REQUEST.set)?

By the way, I'd like to thank Stefan Franke and Pedro Vale Lima who
gave me a pretty quick answer. I did find the answer before they wrote,
but anyway, a thank is not that expensive :-)
Also, thanks to Paul who gave me such a useless answer. :-) (just kidding)

The pcgi.log reads:

The error occurs because a value is appearing in
a pcgi reserved header record, possibly because your
application is sending something to stdout.  I'm
not sure where to tell you to start looking, but
if *all* you have done is uploaded .dtml files to
trigger the error, that's probably the place to
start.  I'm honestly confused why this should
happen.

Usually this means that the Zope process is unable to start up
for some reason (an import error, syntax error, etc.). I'm not
sure how changing DTML document objects could cause this, though.
You didn't happen to change any DTML that is read from the disk
(e.g., HTMLFile objects used from Zope, installed products or 
external methods) did you? If so, there is probably a dtml syntax
error that is being raised at startup time.

You are positively right.
I stupidly wrote <!--#var "some_method(var0=value0, REQUEST)"-->
notice the non-named parameter after a named parameter.

I haven't tried it yet with other publishing mechanisms (ZServer,
ZopeHTTPServer,
which don't use PCGI), but if these servers also dies for such oddities,
this might be
a bug in error handling. Stay tuned for more informations.

Many thanks to Brian and Jeff who took the time to respond to me.

All of my "real" sites are still running under Principia. Recently a

using the latest versions of IE and Netscape are unable to access the
sites now unless they turn off cookies, or they get an error in
cgi_module_publish to do with parsing cookies. (I'm still trying to get
someone to send me the actual error text).

Anyone out there using Principia still? Have you seen this?
Anyone using Zope seen this?

Message-ID: <613145F79272D211914B0020AFF6401907BBDA@gandalf.digicool.com>

Greetings,

As promised, it is possible now to browse the Zope public CVS repository
through the web.  If you're interested in looking at the latest Zope
developments, this is a good place to start without having the check out
your own copy.

This site is also handy for viewing the various evolutions of Zope, and
for getting pretty colored diffs between versions.  If you want to know
the difference between two recent versions of a certain file, cvsweb
will show you in glaring full color.

The web view of the Zope CVS is more fragmentary the the view you get
with the 'cvs' command.  If you want to check Zope out of the public
cvs, it is recommended you just check out 'Zope', which is an options
not shown on the web cvs.  The public CVS uses its module file to stitch
together the various components that can be seen on the web view into a
Zope distribution.  Complete instructions on how to do this can be found
at:

http://www.zope.org/Community/CVS_public_access

The web interface can be found at:

http://www.zope.org/cgi-bin/cvsweb.cgi

In case you're curious, this is not a Zope module but a CGI script
written in Perl.  It can be found at:

http://linux.fh-heilbronn.de/~zeller/cgi/cvsweb.cgi

The first release of Aqueduct docs had a table with examples of
connections strings for some databases. This table disappeared in the
latest docs. Shouldn't it be the case to take it back?

After everything compiled fine I try to import MySQL and get the following
error:

Does anyone have any ideas??
MySQL works fine as well as Zope.
Do I need to install the Sun ld.so patch??

Yes, I've seen it in Principia and Bobo for cookies in the form:

.com.au  TRUE    /       FALSE   933422008       MC1 GUID=083F5B8E21DE11D28B2C08002BB74F3F

The two problems being that cookies are usually only seen by the domain
that registers them, but some badly configured servers (most probably
Microsoft servers by the look of the cookies) only list the last two parts
of the domain name. This is fine for blah.com, but for overseas domains
like blah.com.au it means the cookie is returned for ALL .com.au sites.

This wouldn't be a problem, but since the cookies are returned to Principia
in the form:

MC1=GUID=083F5B8E21DE11D28B2C08002BB74F3F

parse_cookie breaks since it looks for key value pairs WITHOUT an equals
sign on either side. The extra = really confuses it.
To fix it change the re in parse_cookies in cgi_module_publisher.py from:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-=\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'
                     ),
 
to:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'
                     ),

I'd like to be more precise. Suppose my_method is:

def my_method(self):
    if self.REQUEST.has_key('my_var'):
        return "oh yes"
    return "boooo"


Now, I write in DTML:

<p><!--#var my_method--></p>
<p><!--#with "_.namespace(my_var='my_value')"-->
<!--#var my_method--><br>
<!--#var my_var-->
<!--#/with--></p>

Believe me or not, the result is:

boooo
boooo
my_value

You can now understand why I ask how to access the variable
namespace from external methods. How can I test the existence
of my_var, and access its value???

Keep the good work, I might ask you some of your photos for
my daily worship :-)

Hi,

I'm getting really frustrating on this subject. Pff, I believe the
Zope-people have made already a great effort in their documentation. So I
guess my problem is my own bad english. shhg.

I finally got the Postgressql adapter compiled, thanks to two great people!
Thanks for this already.

But now I'm confused? How to use it in Zope? When I go to the product
management I see the all the installed products including : ZPyGreSQLDA
(broken product APyGreSQL).... I guess here is already something wrong
(broken... is not a positive word :-( )

But then, how can I work with it? How can I use it in Zope...? How can I
add it to the 'Add list' . I read of a connection string... but where to
place it?

Sggh, I've read in the manuals, Q&A, ... but I still don't get how to use
it....

Please, somebody, help...!

Thanks in advance,

The Idiot,

Tom.

First thing, if your product is broken you won't get anywhere. So, first
step is to delete the broken product, and shutdown and restart your zope
server. This is because Zope apparently won't replace a broken product
with a working one. 

If it is still broken, click on it, and then on the screen that comes
up, look for the 'traceback' tab on the top of the screen. Copy this
traceback and mail it to the list. 

If your product no longer says broken, then you will be able to go to a
folder above where you want to use SQL methods, and from the pull-down
menu beside the add button, choose to install the SQL Adapter. 

I don't know for certain the format for the connection string, but if
you go to <zope_homedir>/lib/python/Products/ and look in the directory
for the ZPyGreSQLDA and read the top of any *.py file you see, it should
say. 

Once you have a working adapter, you can add an SQL Method, and it will
list your adapter's id on its list of db connections. 

From this point on the documentation in the SQL Guide should be
sufficient.

Good luck!

They'll want to be doing credit card transactions.  Has anyone been working on
a shopping cart app for Zope, or perhaps even utilities to interact with a

Well, this is an interesting question. In my experience, seldom do people
try to munge the DTML namespace from within an External Method. I guess it
could be done (perhaps by passing the special underscore variable to an
External Method), but I wonder if this is really the best way to solve your
problem.

Well let's see what's going on here. You call my method, it acquires the
REQUEST object and looks for a 'my_var', doesn't see it and returns
'boooo'. so far so good. Now you push a namespace containing only 'my_var'
on to the DTML namespace stack and call the method again. Not surprisingly
the method does the same thing as before, it acquires the REQUEST and finds
that it does not contain 'my_var' so it prints 'boooo'. Finally you call
'my_var' which is found in the DTML namespace and 'my_value' is printed.

So the lesson is: the DTML namespace is not the same thing as the REQUEST
object.

For more on how DTML namespace works see my advanced DTML how-to:

http://www.zope.org/Documentation/HowTo/DTML

My advice to you is to keep things simple. It's easy to confuse yourself
with the complexities of DTML. In general, I would suggest that your
External Methods take well defined arguments and return results, rather
than modify the objects passed to them. Then allow the DTML to pass those
arguments and munge its own namespace in response to the results of the
External Method. Of course, this schema isn't always the right one. Finally
I would suggest that you, don't munge the DTML namespace from within an
External Method unless you have a good reason to, I think that this would
make the DTML even harder to understand.

Good luck.

Can I recover? The db doesn't contain anything important so it's really
okay to reinstall, should that be neccessary.

It looks like you're running an older release 1.9.x something?  1.10.x
will automatically fix the database under 90% of the circumstances by
simply truncating the bad record.  This should fix your problem.

BTW, it's always helpful to give information on what release of Zope
you're using.

At a minimum, you can truncate the data file (var\Data.bbb) 
at the position indicated. (Let me know if you need help with this.)

You could also just delete the database (var\Data.*) and
a new database will be created when you restart.

I'd appreciate it if you'd send me the corrupted database
as a zipped or gzipped attachment in a private email.

Also, what version of Zope were you running? What OS?
What products (not included in the Zope distribution) did
you have installed?  Can you tell me anything more about what 
might have led up to this?

I think what you want is access to the dictionary's items() right?

<!--#in "dictionary.items()"-->
  <!--#var sequence-key--> : <!--#var sequence-item-->
<!--#/in-->

The mapping attribute is not relevant here. It means treat
sequence-items as mappings not instances, that is to say, look up vars
with __getitem__, not __getattr__.

The DTML User's Guide is your friend.

Message-ID: <Pine.BSF.4.05.9903301224520.1978-100000@nomad.dataplex.net>

I'm trying to convert shell scripts into DTML methods.

Please excuse the pseudo code. I'm using it to represent the problems
that I am addressing.

set basket_total=0
set taxable_total=0
foreach item( 'apple', 'peach', 'soap', 'pear', 'plum', 'magazine' )
 if (! isfood($item))
  @ taxable_total = $taxable_total + price_of($item)
 endif
 @ basket_total = $basket_total + price_of($item)
endfor
print "Of the $basket_total total, $taxable_total is taxable"


1) Can I generate an explicit list rather than getting it with
as the result of either a database query or enumeration of an object?

2) How do I generate "local" variables.
I know that I could use the REQUEST variable as a global property store.
However, because of nesting, global (REQUEST) variables are not desirable.

I'd like to say something like the following:

<!--#WITH "LOCAL_NAMESPACE (basket_total=0, taxable_total=0)"-->
 <!--#FOR "['apple', 'peach', 'soap', 'pear', 'plum', 'magazine']"-->
  ...
  <!--#SET basket_total=basket_total+price ...>
 <!--#/FOR-->
 ...
 <!--#var basket_total--> 
 ...
<!--#/WITH-->

Does Zope's DTML have constructs to address either of these?

Message-ID: <370125A1.305733AC@kw.igs.net>

Please excuse my lack of zoping intuition but I hoped someone could help
with this problem. I read all the doc's I could find but seem to be
missing something. It goes like this...
I have a ZSQLMethod that returns some tuples. There is a field in the
tuple which I wish to use to lookup an external file and return a jpeg,
if available.
I've created an external method called 'getPic' which I wish to pass the
key field to locate the file with but I can't seem to get at the
variable.
e.g
----------
<!--#in sequence -->
  <td><!--#var pic_key null=""--></td>
  <td><!--#var "getPic( <!--#var pic_key --> )" --></td>
<!--#/in -->
----------

This doesn't work for reasons not obvious to me.

I've tried creating a class to handle the records. No go.
Basically, the External method can't get at the vars defined on each
loop thru the sequence returnd from the SQLMethod.

Any insight would be appreciated.

thanks

I would like to trigger a DTML document to print after the user creates
it. ( There are a few documents in my project that need to be snail
mailed)   
Circumstances aside, they aren't allowed to print from Navigator, so I'd
like Zope to shoot it out without the user having to have a printer
configured.  If a printer is configured to work with the server, can
Zope send it to lpr? I have zero experience there. :-(  

Any suggestions?

Brad,

Thanks.  Regretably, we aren't really using any Microsoft Products (Too
bad, we could have got a virus yesterday :-()  The clients are(and a
browser on the server could be) running Netscape Comm 4.08.  I'm sure
there is a similar way of controlling Netscape--Any body have a guess?

I am thinking about implementing a dynamic site using
zope and as little python as I can get away with.  The
site is modeled after
http://c2.com/cgi/wiki?WikiWikiWeb  

This is a dynamic site in that all the web pages are
dynamically generated and you are allowed to edit any
page right from your browser (sound familiar?) and also
create new pages very easily.  There are many other
implementation of wikiwiki (see the WikiWikiClones
link).

I am interested in any creative ways of dynamically
generating the pages and storing the underlying date in
the objectDB.  Thanks!  Mark

Subject: [Zope] external methods
Message-ID: <003c01be7b40$e0c23560$147800a0@pc-pi0>

Hello,

Thanks for your answer.
In fact, I want to write external methods to replace DTML methods which work
like a charm, but are not very readable (a lot of iterative stuff, given the
fact
that mySQL doesn't support sub-select) and pretty slow.
I have used python for several years right now, but DTML is new for me.

My users can search in our news database in several ways, that are
covered by different SQL queries. However, the output of all these queries
are the same, so I use a single DTML method to display the result.
So the name of the ZSQL Method is only known at runtime, and I use something
like:

<!--#in "_[query]"-->

to display the result. The arguments of the query are taken from the
namespace.
I can also write:

<!--#with "_.namespace(cooked_arg0=some_expr(arg0),
cooked_arg1=some_expr(arg1)"-->
<!--#in "_[query]"-->
<!-- ... -->
<!--#/in-->
<!--#/with-->

If I want to cook some args before feeding it to the query.
All these work from DTML.

Now, I want to write this in an external method.

def results(self):
    for record in getattr(self, self.REQUEST['query'])(self):
        pass # do watever

'query' has to be in the form REQUEST variables (that is not a problem), but
I cannot be sure that any arguments that the query need are all accessible
through
REQUEST.

I wrote this to test wether an external method has access to the entire
namespace,
or only to REQUEST variables.

So I come back with the question: is there any way to access the DTML
namespace
from an external method. Apparently there is not

>For more on how DTML namespace works see my advanced DTML how-to:

I have already read it.
By the way, let me ask you a question (again. I already asked that, but the
answer
was not very clear, and I finally gave up):

<!--#var my_var--> and <!--#var "_['my_var']"--> are the same.
So instead of writing:

<!--#if var0--><!--#if var1-->
<!-- ... -->
<!--#/if--><!--#/if-->

I usually write:

<!--#if "_['var0'] and _['var1']"-->
<!-- ... -->
<!--#/if--><!--#/if-->

But almost everyone told me that

<!--#if "var0 and var1"-->

also work. So I wonder: are <!--#var "var0"--> and <!--#var var0-->
the same??? The DTML User's guide say that in an expression,
variable are not called by default, but _['var0'] calls var0 if possible.

To keep things simple mean I have to write several times the same external
method
with different queries and differents arguments each time. this is not what
I want.
I can remember that in DTML I only need one DTML Method.
I would really like to replace some of my DTML Methods with external
methods.

That's enough for today. Let's take some rest :-)

Subject: [Zope] multiple SUBMIT buttons for same method, with parameter
Message-ID: <129.78.8.1.126.8141.922865008.414.1008>

I can use the following in a DTML document to call a specific method:

  <INPUT TYPE="submit" NAME="mymethod:method" VALUE="Delete this item">

But what if I wanted to have lots of them?

I'd like to have multiple SUBMIT buttons, all referring to the same method
but diffentiated by parameter - possible?

Ie: something like:

  <INPUT TYPE="submit" NAME="mymethod:1:method" VALUE="Delete item 1">

passing the parameter '1' to 'mymethod', and then later

  <INPUT TYPE="submit" NAME="mymethod:2:method" VALUE="Delete item 2">

and so on.

Incidentally, is the ':method' trick documented? - I can't find it in
the DTML guide.

Message-ID: <3.0.1.32.19990331105851.00931700@poirot>

Hi all,

First of all, thanks to all with their great support and help. At the end
of last week I found out about Zope. It looked really interesting, so I
wanted to give it a try. Monday after several problems and with lots of
help I could manage to enter Zope. Not from Apache as I would like, but
from the HTTPServer.
Next I wanted to attach Zope with my PostGresSQL demo database. Boy, did it
gave me some problems (and all because of my lack in knowledge of Linux).
But again several people helped me and today it is solved! Yep, it is done,
the hard work can begin. Now, I've to convince other people that Zope is
the way to follow. 

At first blink, Zope is a really nice and great product. I hope it will get
the attention it diserves.

Still, some work on the documentation, although they already did a great
job! Most thingies are written down.

Kind Regards, Tom.


Now some questions:

1. Have you used CSS-sheets in Zope and how did you use them? Did you
incorporated them into Zope or not? Have you got a little sample?

In Zope, this is pretty easy.
Create a property at your top level of type 'lines' and called 'css' 
(you can also create a DTML document/method if you like). Populate it 
with good CSS things like (this is from the Zope site itself 
actually).

<STYLE TYPE="text/css"><!--
	.clean { font: 10pt Verdana, Geneva, Arial, sans-serif }
	.clean dt { text-decoration: underline }
	th.clean { font-weight: bold; }
	.headbottomrow td { border-bottom: 2px solid #936 }
	.header { color: #004488; font-weight: bold; font-size: 14pt; 
font-family: sans-serif }
	.smallclean { font: 9pt Verdana, Geneva, Arial, sans-serif }
	.smallclean dt { text-decoration: underline }

H1, H2, H3, H4{
  font-weight: bold;
  color: #000000;
  font-family: Verdana, Helvetica, sans-serif;
}

H1{ font-size: 16pt;}
H2{ font-size: 14pt;}
H3{ font-size: 12pt;}
H4{ font-size: 10pt;}

/* end hiding content from old browsers */ -->
</STYLE>

In standard_html_header you put something like
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#var css-->
</HEAD><BODY BGCOLOR="#FFFFFF">

and you're away...

You may want to change standard_html_header so it doesn't crash if 
css is not present.
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#if css-->
<!--#var css-->
<!--#/if -->
</HEAD><BODY BGCOLOR="#FFFFFF">

Now where it starts to get really cool is that all your documents 
*below* the top level get the CSS information by acquisition, but you 
can change CSS information in folders by creating a new CSS property 
or document within that folder.

Tres Neat.

I just installed Zope on a Netscape Enterprise Server (3.6). I compiled
and installed the nscgiauth plugin, and all seems to run OK, except for
one thing:

When I try to add items to the site through the manage screen, I get:

        Not Found

        The requested object does not exist on this server. The link you
followed is either outdated,
        inaccurate, or the server has been instructed not to let you have
it. Please inform the site
        administrator of the referring page.

When I open the frame into a new window, I see that the URL looks
something like:

http://www.foo.bar.net/Zope/GATE/manage/.?%3Amethod=manage_addDTMLDocumentForm

When I edit the URL by hand to remove the "."

http://www.foo.bar.net/Zope/GATE/manage/?%3Amethod=manage_addDTMLDocumentForm

It works fine. What is going on here, and what do I need to do to change
it? I plan on having other people from other departments access resourses
on Zope to create their own objects, and I need this to work right out of
the box.

Thanks in advance for any help.

First off, your the first person (I think) that has come forward with
the information that they are using any version of NES higher than 2.0,
which is what the nscgiauth plugin was written for.  As I have heard
(but don't know) there were some significant changes between the 2.0 and
higher versions of the NSAPI.  So, that you got it to work at all is
pretty good.

This is unreported behavior, which leads me to think that nscgiauth
needs a little tweaking.  As nscgiauth is unsuported you will have to
experiment with this a little.

If your looking to showcase this and you can't spend any time working on
nscgiauth, I would suggest using either Apache, ZServer, ZopeHTTPServer,
or IIS, all of which Zope runs out of the box with.

I think that you missed my point.

"I" can write python just fine. However, every time something changes, new
python functions must be written. It is desirable to allow 
"DTML programmers" to do simple things which they can accomplish with simple
local variables.

What I think I should do is create a function, "LOCAL", similar to REQUEST
that stores temporary variables. Unlike REQUEST, LOCAL would be bound to
the namespace multiple times, each with a different context stack.

<!--#with "_.namespace(LOCAL=LOCAL.create('basketTotal','taxable')"-->
  <!--#call "LOCAL.set('basketTotal', 0)"-->
  <!--#in "['pear', 'peach', 'boot']"-->
    <!--#call "LOCAL.set('basketTotal',
                             LOCAL.get('basketTotal')
                             + priceOf(_['sequence-item']))"-->
  <!--#/in-->
The total basket will cost <!--#var "LOCAL.get('basketTotal')"-->  
<!--#/with-->

Or perhaps we can trick the namespace into showing basketTotal without
the LOCAL.get reference.

Right now I have Apache set up with 4 virtual domains and would rather

Well, the only difference that stuck out to me were the include files for
NSAPI.
nscgi  calls for several, but in 3.x all the header files have been
combined into
one, "nsapi.h". I modified nscgi.c to call for this one header file and it
compiled
cleanly. It does its job very well, and am not all that certain that the
problem I
am having is related to nscgi at all.

Well, I am a contractor and really don't have that option. I have tried to
sell the idea of using Apache here, but they have already bought massively

commercial package, at least for this case.

Message-ID: <Pine.LNX.3.96.990331124956.26207A-100000@taos.kavi.com>

Has anyone built Zope on a BSDI machine? BSDI doesn't support shared
libraries, so everything has to be statically compiled into python.
I just got it to build (python w_pcgi.py finished), but there doesn't seem
to be a new python binary anywhere with everything compiled in. To get it
to compile, I went through and deleted all the '*shared*' from the 'Setup'
files. Any tips?

As a side note, I was planning on using the binary porting kit to get it
built, then contributing this back to the community. But the porting kit
is still Zope-1.9. Is there any plans to update the porting kit.

Thanks in advance for any help,

Subject: [Zope] NotMail 0.1.0 and IMAPAdapter 0.1.0
Message-ID: <613145F79272D211914B0020AFF6401907BBF0@gandalf.digicool.com>

Greetings,

NotMail-0.1.0 and IMAPAdapter-0.1.0 have been posted to the prereleases
area of the site:

http://www.zope.org/Download/Prereleases/Mail

These are first beta cuts.  Both programs are also available in the
public CVS.

IMAPAdapter allows you to work with IMAP folders and messages in the
context of an authenticated IMAP user.  Using IMAPAdapter, it is very
easy to build IMAP client functionality into your Zope site using DTML.

NotMail is a simple web IMAP client that requires IMAPAdapter.  Its mail
purpose is to verify the operation of IMAPAdapter and to provide an
example implimentation of IMAPAdapter's client functionality.  NotMail
is mostly DTML, and what Python there is is just specific to sending and
replying to mail, all other functionality comes from IMAPAdapter.

It is important to note that IMAPAdapter looks like a user folder to
Zope, in Zope parlance, we call this a user database.  It's not a user
folder, because it doesn't not contain users.  If Zope tries to validate
a user against an IMAPAdapter, the IMAPAdapter will contact the IMAP
server, try to make a connection with the uid:pwd that the browser
supplied, returning either a user object or None, depending on the
success or failure of that connection attempt.

This means that using IMAPAdapter is quite simple.  Here is a snip of
DTML to display all an IMAP users mail folders with the #tree tag.

   <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

The user object that IMAPAdapter returns (if the user is valid) is
placed into AUTHENTICATED_USER.  emapFolderTree is one method of this
user object, but there are about a dozen or so more methods to do
various imap related things like adding/deleting folders and listing and
fetching messages.

If you plan on installing and trying out NotMail and IMAPAdapter it is
important to know that you can configure the roles that IMAPAdapter
associates with users that it returns.  The two default associated roles
are 'NotMail' and 'IMAPUser'.  If you want NotMail to work, you will
need to add one of these roles (or any roles you care to define as
IMAPAdapter's default roles) somewhere above NotMail/IMAPAdapter and
then assign that role the 'View' permission for NotMail's DTML Methods.

Have Fun!

-Michel

Um, what VERSION of BSDI are you using?  I haven't usd anything since
3.0, but I SWEAR it has standard BSD style shared libraries, same as
FreeBSD, OpenBSD and NetBSD... It'd be a huge step backwards if it
didn't.... are you sure it just didn't auto-detect the method right?

Alright, I guess I was jumping the gun a bit with my assumptions about
shared library support. It does support them, just not in a format I'm
used to (based on my Linux/Solaris experience). 

Ok, so then mabey I messed up in autodetecting as you mentioned. How would
you suggest I do this?

Here's a few lines of the errors it reports when trying to compile any of
the shared extensions... 

www ~/Zope-1.10.2-src/lib/python/SearchIndex 242> make
gcc  -g -O2 -I/usr/local/include/python1.5 -I/usr/local/include/python1.5
-DHAVE_CONFIG_H  -I/projects/_/python -c ./Splitter.c
ld  Splitter.o  -o Splitter.so
./Splitter.c:105: Undefined symbol _PyString_AsString referenced from text
segment
./Splitter.c:114: Undefined symbol _free referenced from text segment
./Splitter.c:126: Undefined symbol _PyString_Type referenced from text
segment
etc.... (many more Undefined symbol errors)


So... any tips for compiling the Zope extensions as shared libs? I'll
probably keep working on the static python solution, as I'm actually
making progress on this, and I really have no idea where to start with
shared libs on BSDI (no good leads on dejanews, and egroups is
non-responsive as usual).

Thanks,

Here are some things I've found in previous struggles to
get Zope compiled on bsdish systems -- I'm no guru, though,
and I've seen different things work on different bsdx flavors:

o you usually need to add -rdynamic to LDSHARED in your Makefiles
  (this should be reported & worked into python's makefiles, IMHO)

o I havent been able to get threads going on many bsd flavors - so
  you may not be able to pass --with-thread to configure

o I find that extensions will all appear to blow up with unfound symbols

  (such as those you reported) - you need to run make -k and ignore the 
  errors ;)

o On some systems, I had to run make -k, ignore the errors, and rename
  the output .o files for the extensions to .so :(

o I seem to remember having to use shlicc on .so files, but
  I dont recall the details...

Hope this helps - please post a status rpt if you get it working, so
that the gory details will at least be captured. This is the sort of
thing that should be in an installation FAQ somewhere.

In the pcgi/Util directory, you'll find a killpcgi.py 
script.  You could hack it to perform a restart, i.e.
launch a new pcgi process after killing the old one.
This would speed up your initial connect time and be
much faster during debugging (multiple restarts).

My Zope Zen seem to have gone negative (started at zero - and just got worse
:( ) but HOW do you install it.  I could find no mention of any "lever"s in
the ZMG.pdf,
and I have tried as many ways as I could think of to get my Zope (1.10.2 on
ZAP) to read/import the FAQ product, but no cigar - not even close!

Where does one put which files, and what procedure does one go through to
invoke said "Lever" functionality.  Sorry about this, but surely I can't be
the *only* one that is totally lost.  (Come to think of it, maybe I can!)

It certainly looks like you are having a problem, but since I developed to

with you assessment of the problem. Would you please file a bug report in
the collector including this traceback. This is getting deeper than I can

Hello,

I want to *add* content to the default standard_html_header in a subfolder
that we call, say, SF. The standard_html_header in SF reads:

<!--#var standard_html_header-->
<!-- other content-->

But since an object acquire from itself, this did not work (infinite
traceback,
obviously because the stack is filled with recursive calls)
So I wrote:

<!--#with aq_parent--><!--#var standard_html_header--><!--#/with>
<!-- other content-->

And it works for object accessed within SF. But when I create sub-folder
*under*
SF, say SSF, I end up with an error.

How could i write this?

I assume this means Zope will also appear in the Application Server list of
WebReview? (http://appservers.webreview.com).

I got it working using the following code:
<!--#with "PARENTS[-1]"--><!--#var standard_html_header--><!--#/with-->
<!-- other content -->

This only works when this code is in a sub-Folder, and the standard_html_header
can be found in the root folder.

Does python have anything equivalent to Perl's taint mode? Because if it does
then this could be used. That and restricting allowable APIs from internal
methods - again, if this is possible.

Hello,

Sorry for the waste of bandwith. I found the problem.
But the story is interresting enough to be shared.
See at the end of the message.

Well, I found that standard_html_header were called several times, and
that's what caused the error.
Let SF/standard_html_header be:

--------8<--------
<!--#with aq_parent--><!--#var standard_html_header--><!--#/with-->
Hello!
--------8<--------

Then, when I access http://mysite/SF, I get:

--------8<--------
[pretty standard_html_header]
Hello! Hello!
This is the index_html document in SF.
--------8<--------

Why is Hello! printed twice???
From SSF, I get Hello! printed 3 times...

EGroups archives the mailinglist. At http://www.egroups.com/lists/zope you can
find a search interface, which quite often actually works.

Message-ID: <19990301132234.A682@RaVER.duck.org>

Hi all!

I know the question has been up to debate earlier on the list, but still...

I can't get Apache to send authorization headers on to Zope - even tough
I've tried to do what the doc/WEBSERVER.txt tells me to (tried both rewrite
and to let apache authenticate /cgi-bin/Zope/). I also grabbed the
latest Zap release, but that one din't work (broken?). Also had a look at
the zap.conf file and tried using some in my httpd.conf file, but I still
had no luck. 

Now - here is my current config:

Linux 2.0.35
Python 1.5.1
Zope 1.10.2
Apache 1.3.4

Something there that doesn't play well together?

If not - what is wrong??

Appreciate all the help I can get!

This may sound like a bit of an obvious suggestion, but it caught me out.

Check the Directory directive for <apacheroot>/cgi-bin and make sure that
the ExecCGI option is set.

It should look something like this:

<Directory "/www/cgi-bin">
    AllowOverride none
    Options ExecCGi
    Order allow,deny
    Allow from all
</Directory>

Apache 1.3.4 by default doesn't have the ExecCGI option set.

I don't get a traceback because I didn't "fiddle", the FAQ item shows up 
in the control panel, but is not in the Add drop-down.

I'm running 1.10.2 on NT with ZServer.

The 'fiddling' involves disbling the exception handling of the product
initialisation. Normally, a 'Levered' product, that has been distributed, has a
product.dat file. This file contains the compressed pickled reprensentation of
the product, which basicly consists of other Zope objects, with a Principia
Factory.

When Zope can't uncompress and depickle the product.dat file, you only get to
see that the Product is installed, but it doesn't contain anything (which a
Levered Product actually should), and nothing else happens or can happen. If
you want to know more on how to use the 'Lever', read up at
http://www.zope.org/Documentation/Guides/ZMG/ZMG-HTML/ZMG.html#pgfId-986684
(Zope Manager's Guide, Creating Zoipe Products).

When you disable the exception handling in initializeProduct in Product.py, and
restart Zope, it will exit with the traceback I reported.

I have reported this to DC with the Collector, but I used Win98. You are using
WinNT, which is interesting.. Something goes wrong with decompressing the
product.dat file on win32 platforms (Amos says he tested it succesfully on
Linux).

I don't want to get into a language war, but as someone who lives and
breathes security, taint mode is a joke.  Python's rexec module would be
great (as would Bastion), but this is going to require a much higher
level of ZopeZen to implement than I currently have.  Yes I know my
proposal was wrought with huge security problems, but regardless it is
valuable to a some people in the near term (such as those of us on the
STarship).

BTW, requiring write access to the file system is only trivially more
secure.

Unfortunately the ExecCGI option didn't help much. Thanks anyways. 

I'm still stuck at the
point where I get 'Authorization failed'. I've checked and double checked my
Zope/access file and I use correct username and passwd. The filepermissions
should also be set correct (according to the instructions given in the
INSTALL.txt file). Problem is, as far as I can tell, connected to the way
the rewrite module does the rewrite....

Has anyone confirmed that the way the WEBSERVER.txt file says to rewrite the
authorization header actually works?

If it works - is there someone that can say exactly how apache should be
configured and compiled to get it working (best of all also put in a working
httpd.conf also)?

And again.....Appreciate all teh help I can get!

We'd prefer that you start with the Zap distribution, as it removes a
whole bunch of variables.  Can you tell us what was the error with using
Zap?

#=0A=
# This is the main Apache server configuration file.  It contains the=0A=
# configuration directives that give the server its instructions.=0A=
# See <URL:http://www.apache.org/docs/> for detailed information about=0A=
# the directives.=0A=
#=0A=
# Do NOT simply read the instructions in here without understanding=0A=
# what they do.  They're here only as hints or reminders.  If you are =
unsure=0A=
# consult the online docs. You have been warned.  =0A=
#=0A=
# After this file is processed, the server will look for and process=0A=
# /www/conf/srm.conf and then /www/conf/access.conf=0A=
# unless you have overridden these with ResourceConfig and/or=0A=
# AccessConfig directives here.=0A=
#=0A=
# The configuration directives are grouped into three basic sections:=0A=
#  1. Directives that control the operation of the Apache server process =
as a=0A=
#     whole (the 'global environment').=0A=
#  2. Directives that define the parameters of the 'main' or 'default' =
server,=0A=
#     which responds to requests that aren't handled by a virtual host.=0A=
#     These directives also provide default values for the settings=0A=
#     of all virtual hosts.=0A=
#  3. Settings for virtual hosts, which allow Web requests to be sent to=0A=
#     different IP addresses or hostnames and have them handled by the=0A=
#     same Apache server process.=0A=
#=0A=
# Configuration and logfile names: If the filenames you specify for many=0A=
# of the server's control files begin with "/" (or "drive:/" for Win32), =
the=0A=
# server will use that explicit path.  If the filenames do *not* begin=0A=
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"=0A=
# with ServerRoot set to "/usr/local/apache" will be interpreted by the=0A=
# server as "/usr/local/apache/logs/foo.log".=0A=
#=0A=
=0A=
### Section 1: Global Environment=0A=
#=0A=
# The directives in this section affect the overall operation of Apache,=0A=
# such as the number of concurrent requests it can handle or where it=0A=
# can find its configuration files.=0A=
#=0A=
=0A=
#=0A=
# ServerType is either inetd, or standalone.  Inetd mode is only =
supported on=0A=
# Unix platforms.=0A=
#=0A=
ServerType standalone=0A=
=0A=
#=0A=
# ServerRoot: The top of the directory tree under which the server's=0A=
# configuration, error, and log files are kept.=0A=
#=0A=
# NOTE!  If you intend to place this on an NFS (or otherwise network)=0A=
# mounted filesystem then please read the LockFile documentation=0A=
# (available at <URL:http://www.apache.org/docs/mod/core.html#lockfile>);=0A=
# you will save yourself a lot of trouble.=0A=
#=0A=
# Do NOT add a slash at the end of the directory path.=0A=
#=0A=
ServerRoot "/www"=0A=
=0A=
#=0A=
# The LockFile directive sets the path to the lockfile used when Apache=0A=
# is compiled with either USE_FCNTL_SERIALIZED_ACCEPT or=0A=
# USE_FLOCK_SERIALIZED_ACCEPT. This directive should normally be left at=0A=
# its default value. The main reason for changing it is if the logs=0A=
# directory is NFS mounted, since the lockfile MUST BE STORED ON A LOCAL=0A=
# DISK. The PID of the main server process is automatically appended to=0A=
# the filename. =0A=
#=0A=
#LockFile /www/logs/httpd.lock=0A=
=0A=
#=0A=
# PidFile: The file in which the server should record its process=0A=
# identification number when it starts.=0A=
#=0A=
PidFile /www/logs/httpd.pid=0A=
=0A=
#=0A=
# ScoreBoardFile: File used to store internal server process information.=0A=
# Not all architectures require this.  But if yours does (you'll know =
because=0A=
# this file will be  created when you run Apache) then you *must* ensure =
that=0A=
# no two invocations of Apache share the same scoreboard file.=0A=
#=0A=
ScoreBoardFile /www/logs/httpd.scoreboard=0A=
=0A=
#=0A=
# In the standard configuration, the server will process httpd.conf,=0A=
# srm.conf, and access.conf in that order.  The latter two files are=0A=
# now distributed empty, as it is recommended that all directives=0A=
# be kept in a single file for simplicity.  The commented-out values=0A=
# below are the built-in defaults.  You can have the server ignore=0A=
# these files altogether by using "/dev/null" (for Unix) or=0A=
# "nul" (for Win32) for the arguments to the directives.=0A=
#=0A=
#ResourceConfig conf/srm.conf=0A=
#AccessConfig conf/access.conf=0A=

#=0A=
# KeepAlive: Whether or not to allow persistent connections (more than=0A=
# one request per connection). Set to "Off" to deactivate.=0A=
#=0A=
KeepAlive On=0A=
=0A=
#=0A=
# MaxKeepAliveRequests: The maximum number of requests to allow=0A=

# We recommend you leave this number high, for maximum performance.=0A=
#=0A=

#=0A=
KeepAliveTimeout 15=0A=
=0A=
#=0A=
# Server-pool size regulation.  Rather than making you guess how many=0A=
# server processes you need, Apache dynamically adapts to the load it=0A=
# sees --- that is, it tries to maintain enough server processes to=0A=
# handle the current load, plus a few spare servers to handle transient=0A=
# load spikes (e.g., multiple simultaneous requests from a single=0A=
# Netscape browser).=0A=
#=0A=
# It does this by periodically checking how many servers are waiting=0A=
# for a request.  If there are fewer than MinSpareServers, it creates=0A=
# a new spare.  If there are more than MaxSpareServers, some of the=0A=
# spares die off.  The default values in httpd.conf-dist are probably OK=0A=
# for most sites.=0A=
#=0A=
MinSpareServers 5=0A=

#=0A=
# Note: The order is which modules are loaded is important.  Don't change=0A=

#=0A=
# Example:=0A=
# LoadModule foo_module libexec/mod_foo.so=0A=
=0A=
#=0A=
# ExtendedStatus controls whether Apache will generate "full" status=0A=

#=0A=
#ExtendedStatus On=0A=
=0A=
### Section 2: 'Main' server configuration=0A=
#=0A=
# The directives in this section set up the values used by the 'main'=0A=
# server, which responds to any requests that aren't handled by a=0A=
# <VirtualHost> definition.  These values also provide defaults for=0A=
# any <VirtualHost> containers you may define later in the file.=0A=
#=0A=
# All of these directives may appear inside <VirtualHost> containers,=0A=
# in which case these default settings will be overridden for the=0A=
# virtual host being defined.=0A=
#=0A=
=0A=
#=0A=
# If your ServerType directive (set earlier in the 'Global Environment'=0A=
# section) is set to "inetd", the next few directives don't have any=0A=
# effect since their settings are defined by the inetd configuration.=0A=
# Skip ahead to the ServerAdmin directive.=0A=
#=0A=
=0A=
#=0A=
# Port: The port to which the standalone server listens. For=0A=
# ports < 1023, you will need httpd to be run as root initially.=0A=
#=0A=
Port 80=0A=
=0A=
#=0A=
# If you wish httpd to run as a different user or group, you must run=0A=
# httpd as root initially and it will switch.  =0A=
#=0A=
# User/Group: The name (or #number) of the user/group to run httpd as.=0A=
#  . On SCO (ODT 3) use "User nouser" and "Group nogroup".=0A=
#  . On HPUX you may not be able to use shared memory as nobody, and the=0A=
#    suggested workaround is to create a user www and use that user.=0A=

The only difference between your setup and the setup used to compile Zap
is that Zap was compiled on a RedHat 5.2 machine, with the stock 2.0.36
kernel.  Your using 2.0.35, does that imply RedHat 5.1?  If so there
might be an incompatability with Zap on 5.1.  Has anyone on the list
gotten Zap working on this platform?  Also, please send us the details
of the error you get with Zap.  When you say it's broken, how does it
break?  Does the starzap script fail to run?  Does it say 'Apache did
NOT start sucessfuly' and then spit up the last 10 lines of your error
log?  If so, what are those lines?

Can somebody please help me out. I've read through most of the postings to
the list, but I'm still in the dark.
I have defined a DTML documentproperty of type lines. Each line represents
the ID of another DTML document. When using: <!--#in notes-->   <!--#var
sequence-item-->  <BR> <!--#/in--> I get the ID's. I tried all kinds of
variations on this code (including the ones suggested by Amos) but are still
unable to turn those ID's into rendered objects.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC3E@peter.sths.org>

You need to install python... Or adjust the Makefile.pre.in to look at
Zope's internal python, instead of trying to find the external one.

Actually, from a quick runthrough of the Makefile.pre.in, you should set
the enviroment variable PYTHON to point to the local python binary; I
mean the one internal to zope, like 

PYTHON=/home/zope/bin/python
export PYTHON

(in bash)

or setenv PYTHON /home/zope/bin/python

(in tcsh) ... (and no I am not quite certain on the syntax here).

The 'make -f Makefile.pre.in boot' appears to call $(PYTHON) with
parameters that cause it to return the proper location for the python
configuration files, etc.

Good luck.

Subject: [Zope] NotMail 0.0.5 alpha release
Message-ID: <613145F79272D211914B0020AFF6401907BAB1@GANDALF>

Greetings Zopesters,

I have been working on a little pet Zope Product project for months now.
Getting hired at digicool put the brakes on it a little but I have
finally gotten the time to polish it up a bit for alpha release.

Check out:
http://starship.python.net:9673/crew/furtrapper/NotMail

for NotMail.  NotMail is a clone of 'other' popular web-mail interfaces.
Please download and evaluate.  But first a word of warning:

NotMail is alpha.  It is being released with the intention of harvesting
other developers who are interesting in breaking it, fixing it, and
improving it.  Although it is a cool program, it is unstable (try
pointing it at Exchange!) and not complete.  I have tried to document it
in code as much as possible, and it does contain a nice README.txt.  You
are expected to be able to infer the workings of NotMail by the source,
or by telepathy, whatever.  If NotMail makes your hard drive partition
go bye-bye or makes your imap server think it's a dhcp server that's the
way the cookie crumbles.

Okay, now a word of license:

NotMail is released under the GNU General Public License.  Give yourself
a piece of mind and send the Free Software Foundation a donation.  You'd
do it for NPR wouldn't you?

Now a kind word about Digital Creations:

Digicool has been kind enough to let me waste a small fraction of my
time to release this today.  They also let me use their computer to
check my personal mail, etc.  Please don't infer that because I work for
Digicool that NotMail is a product of Digital Creations.  Please do not
submit NotMail bugs to the Collector or send reports to
support@digicool.com.  These things are for Zope and other Digicool
products.  It is ok to discuss it in the list but I'd prefer all
discussion happen using the cool Confera discussion that can be found in
the same place you can get NotMail.

Regards,

Michel

What I did:

1) Extract the Zap distro into my top level Zope dir. Entered the Zap dir and
did ./startzap. 

This happened:

'./startzap /usr/local/Zope/Zap/bin/zap: No such file or directory'

2) I figured the httpd equivalent 'zap' was broken and replaced it with my
httpd (from apache 1.3.4). Again I fired up zap with ./startzap.

This happened:

No complaints this time. Apache (or rather zap) fires up correctly, but when
I try to reach the server with netscape or lynx (http://localhost/, (I
changed port back to 80)) I get 'Document contains no data'.

Same goes for trying: http://localhost/cgi-bin/Zope/manage - I get 'zero
sized reply', 'The requested URL could not be retrived'.

Now - seems like there are some settings missing from the zap.conf file?

Or if nothings wrong - then maby give the readme-file a facelift and
make it more clear to ppl like me what to do to get it running.

Zope seems just too good to just let go!!

Hope to get it running soon

I just did a fresh install and this works for me.  Can you run bin/zap
by hand from the shell prompt?

Your own httpd binary might not be compiled properly for Zope use, check
out the Zap FAQ at http://www.zope.org/Community/Projects/Zap.  Doh, I

Subject: [Zope] Is a JPython implemention within the realm of possibility?
Message-ID: <93C0BE6A6D6AD211BC7400A0C9D8FE87731223@exton1.bentley.com>

I am wondering if it is within the realm of possibility that the Zope
project might eventually support operation as a Java program (under JPython)
in addition to operation under traditional Python.  I know it would probably
be a large undertaking and that there may well be better places to spend
precious energy, but I thought I'd register my interest in the prospect.

In our case it is a given that a specialized JVM will be embedded in all of
our products and more and more of our own source will be written in Java, so
code which can integrate with Java easily is all the more interesting to us.
We already have a product which uses traditional Python behind a web server
to provide an entirely through-the-web user interface for product
configuration/administration. My aim has been to replace the traditional
Python with JPython since we'll have lot's of Java stuff we'll want to be
using on the server going forward anyway.  It looks like Zope would enable
us to do what we are already doing more easily (and therefore better). So
here's hoping we'll one day see Z-over-P-over-J.

Yeah.  I know it would have to be slower.

Zope looks cool.

I am not the expert about this, but: Zope is written entirely in Python,
except for a few 'kernel' like components written in C.  If you
translate these components into Java, you might just have something
there.  I'm not a Java guy so I have no real idea.

> Yeah.  I know it would have to be slower.

From what Ken was telling me JPython is actually quite well designed and
speedy, even for a Java program. :)  If you've commited yourself to Java
then I assume you've allready resigned yourself to the performance
penalty and are considering it in your engineering goals.  Performance
may not be your primary goal in the first place.

This was one of the things that I hoped to see by going Open Source.  So
far there have been ports to operating systems that we just wouldn't
have supported, which is a great to see.  I'm intrigued by someone that
really knows Java picking up a JZope effort.

As for Digital Creations, I doubt you'll see us focus on it unless one
of our consulting customers requires it.  Same old story -- never
enought time :^(

Subject: [Zope] Connecting Zope to Sybase: Linux or Irix ?
Message-ID: <199903011940.LAA18485@sam.engr.sgi.com>

I'm just beginning with Zope, and just beginning with a
project to develop some new software product management
(bug tracking and such) tools for use within Silicon
Graphics (SGI).

Zope appears to be an excellent fit for many of our
needs.

I will need to connect with an existing large Sybase
database (the existing bug data).

I can freely choose to use either Linux or Irix for
the server side operating system.

From which server O.S. would it be easiest to get Zope
connected to Sybase?  Something I read on www.zope.org
led me to suspect that I should use Irix, so that I
can use our Sybase licensed library, and that Linux
wouldn't work, because of a lack of the needed library.

Is that so?  Any other obvious factors that I should
consider in this choice?

Hmmm - I'm a slackware guy. And no glibc guy either....

Still the zap bin starts from the prompt and when I changed some settings in
zapctl then ./startzap also worked. That is the zap process shows on ps, but
I'm not able to connect to the server with any browsers.

Now - whats wrong?

My guess is that the hardest part of such an undertaking would be to
convert Jim's extensions to Java/JPython.  Specifically, ExtensionClasses
and Acquisition are probably the hardest to do (I believe many of the
others are just fast implementations of Python versions).  Jim Hugunin
mentioned that he had thought a bit about ExtensionClasses, but I'm not
sure how far that went. The efficient POS and other extensions are also
clearly a significant undertaking, but maybe not as hard to translate.

However, I don't see it happening until someone has a commercial
motivation to invest the large required number of hours into it.

Zope relies on a lot of code in C as well as Python, so I doubt you'll see
Zope on JPython anytime soon.

However, ZPublisher (Zope's ORB) could be made to work with JPython without
too much trouble. In fact a while ago I tried this and succeeded, though it
was quite slow. The main issue is that ZPublisher uses 'regex' while
JPython uses 're'.

FWIW, my shop is running Sybase OpenClient 11.1.1 on IRIX 6.2, 6.4, and 6.5
on a Challenge/S, O2000, and Challenge/L, respectively.  I successfully
installed ZSybaseDA into Zope on the Challenge/S; haven't tried on any others.

Also FWIW, I have experienced nothing but problems getting PCGI to work on
any of the IRIX platforms; your mileage may vary.

(Coincidentally, the company I work for owns a couple hundred SGI boxes and
we keep our inventory of them in a ZPublisher app...  it's on mySQL,
though, not Sybase.  OTOH, our request tracking system is a
ZPublisher-on-Sybase app.)

The last version I tried was the one distributed with Zope 1.9.0 - it
exhibited the same fail-on-process startup behavior as previous versions,
so I went to ZServer as a stopgap until I could complete a FastCGI
replacement.  I'm now using FastCGI, so it's no longer an issue.

Actually, some time ago I sent Jim some code that was a regex mockup
implemented using re.  It didn't do all of regex, but enough to make
DocumentTemplate work.

At first blush, I'd say that the host you've defined as the target of 
mailhost does not accept or is not running a mailer on port 25.

Are you certain you have mailhost setup correctly?

One can join now and pay for a half year $50/yr 
or $25 for half.  Membership wouldn't be effective
until April 1st (a Foolish day!) 

So, Zope is cool and so is Python.  I am considering
joining PSA on the strength of Zope and Elegance
of Python but I'm concerned that Python doesn't seem 
to have much "MindShare" like Java or Perl.

Ok so our local Borders has only one book on Python:
"Programming Python" by Mark Lutz (Pub: O'Reilly)
A great book that is dated 1996.  The shelves are
full of books on Java and there are quite a few Perl books.

What is the BIG PICTURE here?  Is Python so good
that lot of programming tomes are unnecessary?

Why is there so little press on Python and so much
for the less Elegant and slower Java?

Is Python a "secret weapon"?  If so, the secret should
get out to the world so Python gets more mind share
and doesn't develop cobwebs.

***So, where are the rabid Python fans?***
Yes, a bunch of them are on the ZOPE list.

Great answers to these questions will only help ZOPE!

I'm using pcgi from 1.9.0 (README says it's 2.0a4) under Irix 5.3 (yes, I
know, I keep bugging the sysadmin to upgrade :) ).  Occaisionally, pcgi fails
to start up, logging "Interrupted system call  (116) unable to connect, fd=4".
I also had the same problem when using FastCGI w/ threads: the application
would hang and I'd get an "interrupted system call" in the log after a while.
I have never experienced either of these problems under linux, so might this
be an Irix problem?  I remember that Philip also suspected an Irix
"sockets-and-threads-don't-mix" problem, which appears to be what I have
experienced as well.  Philip, is theaded FastCGI still broken on Irix?

As a language qua language, Python is so good in design
and implementation that it has few dark mysteries that
require a lot of documentation to explain.

The existing Python books are quite good, with at
least 4 more in the works.  More Python books are 
necessary to explain things like Win32/COM programming, 
for instance, than the language itself.  Perl has
lots of books, because for the past 2 years, almost
anything that offered to make Perl programming easy
was given shelf space.  Java has lots of books
because almost everything in Java has to be written
in Java, and the Java libraries have been a moving
target for so long.

More important than the number of books (how many
Perl books do you really need, after the Camel?) is
the level of support/platforms in the Python community,
which is quite high.  It will probably never attain 
the proportion of mindshare that Perl or Java has,
but is has critical mass, and a lot of compentent people
who contribute code.  Too many companies now rely upon 
Python as their core development language for it to go 
away anytime soon.

More importantly:  You'll spend more time learning about
the eccentricities of whatever your environment demands,
be it Unix, Windows, web servers, CE devices, COM, Tk, etc.
than learning the language itself.  This is Python's 
great (and under-reported) strength.

Message-ID: <36DB1478.E2D7915E@avalongroup.net>

Hi all,

This is probably more of a newbie Linux question than a newbie Zope
question, but I'm going to ask it here anyway:

I would like to connect Zope to a database, so I have setup both
PostgreSQL and MySQL. My reading tells me that MySQL is probably the
better choice as a web backend (Any comments from those of you more
knowledgable than I would be appreciated!) So I downloaded the MySQL
source, compiled, installed and tested it. It looks like I did it right.
I then downloaded the ZMySQLDA from the Zope site.

I have followed the directions--I think, but get the following error
when trying to do the initial make:

[tjg@puddleglum src]$ make -f Makefile.pre.in boot
rm -f *.o *~

FYI:  I know of at least 5 other Python-related book projects in various
stages of development.  One of those should be hitting those same shelves
in April sometime (http://www.oreilly.com/catalog/lpython/).  It even
mentions Zope in a couple of places.  [Disclosure: I'm a coauthor of said

Python is certainly easier to learn than some other languages.

Mostly, because Java is backed by a multibillion dollar company with lots
of $$'s for public relations.

ObZope: I'm having a hard time with the 'access' file -- it looks as if my
Zope installation (w/ ZServer) only accesses the first entry in the file.

A perfectly reasonable suggestion - and one that I have made many times myself!
<g>

I did, in fact, RTFM - but the FM makes absolutely zero mention of anything
"leverish", to adopt a seemingly Zopish mode of Englishish. ;-)  I followed your
link given in another message, and realised that what I had been reading about in
terms of Product Distributions was (I think) what you refer to as the "Lever".

IAC, I followed the instructions given, and when it didn't work I went back, and
worked my way through the Product Tutorial exercise - excellent!   The POLL
product works fine!  But the levered faq product .DAT file apparently failed to
unpickle - as described by others in this thread.  My product management screen
shows the FAQ product as installed, but the actual product directory still has
just the three files from the tarball.  In my case, however, it is on a Linux ZAP
system - so the problem is not confined to Win32 as others have conjectured.

Hope this helps, and apologies for the lack of specifics in my previous post.
Can we please have the term "lever" clarified and documented a little better.

My experience was MySQL had better support for large
streams of text data and blobs than PostgreSQL.  However,
MySQL also lacks support for transactions.  This probably
contributes to its speed, which in turn makes it popular
for web apps.

THis is completely correct.  The access file is ONLY for the
global-overall-uberuser :-)  Everything else should be defined in the
database itself :-)

I assumed that the .DAT file contained all the component DTML and PY scripts etc
and that these would be expanded into the Product's home directory somehow.  Is
this not the case?  Is the .DAT distribution a way of  distributing the objects
without the source ? (more Cathedral than Bazaar)

No - but it does show up in the installed products control panel.

Note that you could, pretty easily, write a new UserFolder type object
which worked off an access file. Could be useful for people who are generating
the access file from an /etc/passwd file, or whatever.

You could also skip the generation step and write a UserFolder which
works off of /etc/passwd.  In fact, NotMail could use this as a helper
too.

Has anyone else experienced a problem getting Explorer to connect with
Zserver?  I have no problem with any version of Navigator but MSIE 3.01 and
4.0 and 4.5 for both Mac and Windows throw up an error box claiming an
"error with Explorer's internet extensions has failed".

Very baffling, I can connect just fine via telnet using the following
requests, ZServer (medusa) returns a proper html page.

(note the difference in the sent host and recieved host, the host arg in
the start script sets the host for the ftp server, not the webserver...)

I can see nothing in the responses that would cause MSIE to fail, note this
has been tested from four different PC's on three different ip's, including
a local connection from my Lan.

Strangly enough I did a stream capture and hit my server and the startship
server (also running ZServer) and the two responses differ even though the
requests were from the same browser on the same connection.

Do starships ZServer and mine differ?

My  http_server.py  script carries RC_ID of:
 "v 1.4 1999/01/18 22:44:49 amos"  I downloaded a fresh copy of ZServer
when I grabbed the newest copy of Zope.

Any clues? I've been documenting and testing everything I could think of,
I'd report a bug but it seems MSIE works with the Starship server, so I
think it's not a bug so much as something wrong on my end?

Slackware V 3.6
Zope v 1.10.2

I understand the security problems inherent in ExternalMethods; unfortunately,
without them, Zope is merely an "also-ran" in the web applicaton race, from my
perspective.  DTML in isolation is not an "ASP-killer."

I'm CC'ing the Zope list, in hopes that someone there can either allay or slay
our fears.

It seems to me that the security problem is that ExternalMethods can get access
to "sibling objects" of the object on which they are invoked, right?  I mean, if
we could make the siblings inaccessible, and acquired properties read-only, then
we should be ok, no?  Ugh, I don't grok acquisition well enough to tackle that
myself, I fear.

Message-ID: <199903020647.RAA07473@mbuna.arbhome.com.au>

from inside DTML, is there a way to say "don't process any further DTML,
just return this to the user"?

What I'm looking at is a small DTML snippet that gets included at the
top of a number of pages, and looks for a particular variable to be
set. If it's not set, it should just display a small "please enter a
widget name" form which submits back to the same page, and not display 
the rest of the page at all.

will just doing a RESPONSE.redirect() automatically do this?

I'm making a Zope "Product" for managing and creating student surveys
(which I hope to contribute via zope.org) but I'm having trouble with a
couple of techniques:

1.	How does one enable a dtml file that is instantiated as in
		my_dtml = HTMLFile('my', globals())
	available for editing in the products' management screen?

	There's probably more to this - as at the moment the management
	screen goes straight to the "index_html" form as with the "Poll"
	Product.

2.	What's the approved way to catch database errors in methods?

	I'm creating tables on the fly, and need to check if the table
	exists before trying to create it. (I'd use a "tables" method if
	all the database interfaces supported it. I'd also use a try/except
	but the database objects have different names for their exceptions.)

Message-ID: <8174B1EE3D2CD21180960000F8056723CFB321@telisnt1020.is.tel.co.jp>

Hi All!

First off, I'd like to thank Digital Creations for an excellent (and
really fun) product. 

I'm building a prototype web site interface for a database where I
work using Zope 1.10.2 and the ZOracleDA product and have a some
questions. 

1. When trying to do a join (a lazy query, I know) like:

   select a.*, b.*
   from tablea a, tableb b
   where a.b_id=a.id

   Both tables have an ID column so Zope raises a 'ValueError'
   exception with the  message 'Duplicate column name, ID'.
   I wonder if instead of raising an exception something like the 
   following could be done?

   A diff of Shared/DC/ZRDB/Results.py:

120,131c120
<                 #raise ValueError, 'Duplicate column name, %s' % name
<
<                 #instead of error, append an extension to
<                 #create a unique name
<                 tempname=name
<                 nameext=1
<                 while schema.has_key(name):
<                     name=tempname+'_'+str(nameext)
<                     nameext=nameext+1
<
<                 #update with newly created name
<                 item['name']=name
---
>                 raise ValueError, 'Duplicate column name, %s' % name


   I tested this some and it seems to work. Are there any problems
   that could be caused by doing this?

2. I'll post the other questions separately because they are
unrelated.

The .DAT file only contains information to be added to the Object Database. It
won't be expanded into files onto your harddisk.

Zope stores all instances of classes in it's object databse, via a process
called 'pickling'. This, in simple terms, means that all data stored in an
object is turned into one stream of data that can be stored in a file.

As a 'Levered' product contains nothing but instances of classes, not the
classes themselves, it suffices to distribute only the compressed pickled
contents of the product. The source for the used classes you allready have (at
least with the FAQ you do, it uses only DTML Methods and Folders), and the DTML
scripts can be viewed in Zope, so you do get all the source.

The objects that make up the product should normally be automaticly
decompressed and imported into Zope, but the decrompressing seems to be
failing.

val wasn't set to None and so the null attribute never got used. Since
None is false, the above should be OK. (It seems to work for me,
anyway :^)

That works fine if it's all one big DTML method. But what if you have
a series of pages which each have
<!--#var check_widget_settings--> at the top.
inside check_widget_settings I want to be able to say "if this, then
enough. don't return back to the enclosing objects, just send what
you have now." kinda like a DTML exception :)

Message-ID: <153C1D93564@sahara.cspt.es>

Does anyone have any more information on AUTHENTICATED_USER? We saw a while 
back that it has properties (AUTHENTICATED_USER.has_role(['Manager', 
'Editor'])). I would like to be able to get the user name, and use that to 
index simple files for users. Is there something like 
AUTHENTICATED_USER['UserName']?? This is essentially the information that is 
returned if you try <!--#var AUTHENTICATED_USER-->. However, if you try 
something like <!--#if "AUTHENTICATED_USER in objectIds()"-->, it does not 
work.

The only way I have been able to use this information so far is to put 
<INPUT TYPE=hidden name=userID value="<!--#var AUTHENTICATED_USER-->">
in a form, and pass it in a REQUEST to another page. But I want to be able to 
get this information directly. I have even tried REQUEST.set('myUser', 
AUTHENTICATED_USER) inthe header, but this has the same problem 
(unsurprisingly) as AUTHENTICATED_USER itself.

Any hints?

Thanks,

JP

AUTHENTICATED_USER itself is an object -- the reason
<!--#var AUTHENTICATED_USER--> gives you the user name
is that it effectively does an str() on the user object.

To work with the user name directly, you can use the
getUserName() method of the user object:

<!--#if "AUTHENTICATED_USER.getUserName() in objectIds()"-->

I am not sure I understand your problem. Default arguments can be given in
the definition of the function. If you need to pass a variable in an
external method you can just do
<!--# var "mymethod(myvariable)" -->
Additionally the self argument in the external method definition is
replaced by the object (or containing folder) that calls the method so you
have access to the namespace of the object through self.

Where is your function located? Is it an external method? In this
case imports in the method's file work fine, but only inside Zope's
search path (practically, the installation path and lib subdirectory).
A good place to put your modules and packages is the 
lib//shared/<your company> dir.

Use <!--#var expr="AUTHENTICATED_USER.getUserName()"-->

More hints linke this can be found in the User.py file in your
lib/python/AccessControl directory.

The following functions could be usefull:

getUserName(self): Return the username of a user
getRoles(self): Return the list of roles assigned to a user. 
getDomains(self): Return the list of domain restrictions for a user
allowed(self, parent, roles=None): Check wether the user has access to parent
hasRole(self, parent, roles=None): Check wether the user has the specified
roles
has_role(self, roles): Check wether the user has the specified roles

allowed & hasRole are one and the same. When called with parent=None, it
just returns wether the user has the named roles. has_role also checks for
roles, but doesn't automatically include the Anonymous role. So,
hasRole(None, 'Anonymous') always returns true, but has_role('Anonymous')
returns false for every user that has been authenticated.

Note that AUTHENTICATED_USER is always defined, also for anonymous access.

Here is a little example of what you could do with these functions:

<!--#comment-->Display user info<!--#/comment-->
You are the user named <!--#var expr="AUTHENTICATED_USER.getUserName()"-->.<P>

<!--#if "AUTHENTICATED_USER.getRoles()"-->
  You have the following roles:

  <!--#in "AUTHENTICATED_USER.getRoles()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You have no roles defined.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.getDomains()"-->
  You are allowed to log in from the following domains:

  <!--#in "AUTHENTICATED_USER.getDomains()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You can log in from any domain.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.has_role(['Manager'])"-->
You have the 'Manager' role.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['Anonymous'])"-->
You have the 'Anonymous' role. You are therefore an anonymous user.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['nonexistent'])"-->
You have the 'nonexistent' role.<BR>
<!--#/if-->
<!--#var standard_html_footer-->

The last call to has_role is to show that the user defined in the 'access'
file in the root folder of your Zope installation, has ALL roles, including
non-existent ones. And even more interesting, the call to getRoles() will
get you 'manage', a misspelled version of the 'Manager' role. This is
probably the only way to reliably recognize the superuser.

Well, it's actually deeper than that. You are correct in saying
that DTML alone is not an ASP-killer. Consider the similarities
between Zope and, for example, ASP/COM (though the same holds true
for practically any other system as well):

ASP lets you use the services provided by (COM) objects, which may 
be provided by the server or provided independently. I'm sure that
MS tries to make the server-provided objects fairly safe, but there
is _nothing_ stopping a programmer from writing and installing a COM
object with an evil() method that wipes out your C: drive, except the
fact that presumably the sysadmin exercises some control over making
these independent services available.

The same holds true for Zope (and any other app server out there). 
Like ASP/COM, External Methods give you the ability to provide more 
powerful services for use by your application. It also gives you 
exactly the same problems (though I'm sure that evil() method could 
be developed in a quarter of the time in Python :)

Basically, with power comes responsibility, and I can't really imagine
any system that could _safely_ allow possibly-untrusted people to write
(basically) arbitrary code. It's not even really a matter of what
services
are or are not available to those people. I'm sure that many, many hours

and much brain-power went into the design of Java's security mechanisms.
Even so, if I were a web site manager I still couldn't let untrusted
users write their own arbitrary java code to run in my web or app
server.
Even after I had figured out a way to wall off every service I could
think
of that could possibly be harmful, the user could still probably just do
the Java equivalent of:

  while 1:
    pass

Zope DTML goes to a good deal of trouble to minimize these problems 
in DTML itself, and we would certainly consider any concrete ideas
on how to make External Methods safer. Can you give me some examples
of other app servers that you feel deal with safety of external 
services in a better way? I'd be happy to do some looking into how
others are dealing with this.

Make your Product a Folderoid (zopespeak for a Folder Object) that
contains it's own user interface which the manager can edit.  Your

Folder.  Confera and NotMail both do this (Confera does it a little

There absolutely does need to be an "unprotected mode" available though - the
system designers might *need* it to do scary destructive things like deleting
files. Zope should not get in the way.

Seems that the activity on the Zope list has exploded. A lot of the

believe a FAQ on the Zope site is neccessary.

Do the folks at digital creations have time to set it up?

This is an excellent post.  I want to add that _getPassword() is a handy
function also if you want to use your Zope user to authenticate into an
external system, like POP3 or IMAP.

Hi,
The followowing problem seems very fundamental to me.
I already did a post to this group to this topic and I got the following
answer:

On Wed, 13 Jan 1999, Dr. Armin Tschammer wrote:

The "print" goes directly to the webserver, which confused it: it
expects
HTTP headers like "HTTP/1.0 200 Okay".

The "return" sends your data to *Zope*, which then does the header stuff

for you.  Same with cookies, content-type, etc.

Summary: dont use 'print', or redirect stdout to a log file.


Now the problem is deeper, what shall I do when I am import C++ Modules
in Python ( extending Python),
and that modules are writing to the stdout via "cout" or "printf", I
have no influence to that.


If I change the stdout via "freopen( "file, "wr", stdout )" or stuff
like that, I have no chance to switch back
to the *real* stdout  ( look at the c-faq of comp.lang.c ), and I *have
to* switch back because of the cgi-mechnism,
which uses ZPublisher.
The only the chance to handle stuff like that is to work with two
processes in the Zopemechanism.
A Zopeserver which tells the Zope Client to start a pythonfunction. Now
all stdout happens on the
client and the server listen for a string on a socket ( or something
similar ). Now when
the server gets the string it does all necessary wrapping ( content-type
and so on ), and
send it to the Xserver via its stdout.

Or is there a less complicate solution ?



 Thanks in advance

   Armin

That's unfortunate, but we understand.  Getting *anything* to work with
Apache's mod_rewrite module is quite a chore.  It doesn't help that
distributions like RedHat 5.2 ship it in a broken way, then people blame
us for it, then we track down a problem that is completely outside Zope.

Did you follow the recommendations to start with the built-in webserver
before trying integrate with Apache?  If so, did that work?

I believe this is allready under construction:

By far from incomplete, but it is the right direction. I think Amos' FAQ tool
should be utilized there somewhere, and maybe some people from this list
willing to help out DC should fill it in, because it looks like Ken Manheimer
(who has been charged with community communications) allready seems overloaded.

What about

select *

    where a.b_id=a.id


Wouldn't this give you vars called a.id and b.id?

Hmmm... I bet Zope won't like that.

It occurs to me that a DTML document could contain this in a transparent
sendmail form, assuming there is already a handy Mailhost set up, to capture
and mail off the password of anyone browsing the page...

Not really -- you can't access _getPassword() from DTML. You would
have to write an external method to do that (which implies that
you have access to the filesystem, and could get the passwords
anyway if you wanted them that bad...)

While we are on the subject of AUTHENTICATED_USER, I would like my users to
be able to "logout" so that they then become anonymous again.

Any ideas?

I have seen this on Dejanews. It would be useful so that authorized users
don't leave themselves logged in if they don't quit Netscape.

	Is there any chance that you're trying to do something
	like:

	select *
	from a, b
	where a.b_id = b.id
                       ^

More generally speaking, we should be organizing the Zope documentation
project. There was word of it before, but haven't heard much on it
recently. In fact, the messages that I can find in my mailbox on it is
people saying we should start such a project :). I'd obviously be very
useful.

As an example: I myself have sent some (obscure) questions to the list
the week before last, and have only managed to receive an answer that
confused me more (I welcomed the answer though, of course!). I sent more
questions and observations last week, but haven't received answers yet
(perhaps it's because I'm doing something fundamentally wrong with Zope
but I'd like to hear it if that's so). Of course I'd like to see my
questions answered.

A FAQ would help filter out all the less obscure questions so that my
obscure questions might get answers. :)

So, the Zope Communication Project (hereby started if it doesn't exist
yet, this is open source after all :) should make its first priority to
create a fairly exhaustive FAQ. I currently have some time to invest in
the ZDP (he said, tempting fate; work's slow right now, but this can
change quickly).

Anyway, I'll help. If only with the *questions* side of the FAQ,
perhaps, but I can help. :)

Initial Plan of Action for the ZDP:

- Produce a fairly exhaustive FAQ, mining the mailing list for good
questions and answers.

- Organize the ZDP itself. :)

Regards,

Martijn

Message-ID: <36DC17B8.7F5CFF6A@pop.vet.uu.nl>

Hi there,

Hereby I announce in absolute adhoc anarchistic fashion the Zope
Documentation Project. The Zope Documentation Project aims to generate
documention on anything Zope.

The Zope Documentation Project needs people who wants to help. It needs
these people to get organized.

To get focused, I propose the ZDP's initial project is to provide FAQs
on various Zope topics. We can mine the mailing list for good questions
and answers.

The ZDP asks everybody to contribute. Right now we need everything. :)
We need questions and answers, and we need to categorize these in
separate FAQ sections. We need Zope webspace somewhere to put up the
FAQ, I assume using the FAQ product. We need to develop the FAQ product
further, if necessary. We need whatever you can think of.

The prime mean of communications for the ZDP is the Zope mailing list,
until further notice. I suggest that to keep the mailing list somewhat
organized we prepend our mailing list subjects with '[ZDP]'. If somebody
has a better way, we'll do it a better way.

Note that while I'm sending out this message, I'm not anything official.
I'm just attempting to get the ball rolling.

*nudges the ball*

Regards,

Martijn

Could it be a 1.5.1 vs 1.5.2b2 thing?  I have 1.5.1 and it failed for me.
Is the zlib.pyd in 1.5.2 based on a newer version of the zlib library that
may not be forward compatible?

I don't have any experience with Zope or even Python, but am I right
in guessing that this looks like a problem with the python binary and
not with Zope?  Any ideas to precisely what the problem might be?

python is v1.5.1.
C compiler used is gcc 2.7.2.x.

I finally got it working - just couldn't get it off my mind. Was kinda
mindblowing the whole thing but finally - YES I MADE IT! :)

What I did was to jump off the mod_rewrite thing and try let apache handle
the authentication all together. At first I didn't know of the htpasswd
binary (stupid as I am) so things didn't work at first. Then htpasswd lit my
eyes - did the 'htpasswd -c' thing and ended up with a working AuthUserFile.
Now the trick was to configure the damned thing in httpd.conf - this worked
out ok:

"""
ScriptAlias /cgi-bin/ "/usr/local/apache/cgi-bin/"

<Directory "/usr/local/apache/cgi-bin">
	AllowOverride None
	Options FollowSymLinks ExecCGI
	Order allow, deny
	Allow from all
</Directory>

AddHandler cgi-script .cgi

<Location /cgi-bin/Zope/>
	AuthType Basic
	AuthName Zope-in
	AuthUserFile /usr/local/apache/conf/zope_auth
	require valid-user
</Location>

# 'zope_auth' created with htpasswd -c /usr/local/apache/conf/zope_auth \
'username'

"""

Actually - just like the manual tells me to. I did some wrong links and
generally fucked things up. Thanks for keeping me going at least (that goes
to all U ppl answering me) - sorry for taking up your time.

Message-ID: <613145F79272D211914B0020AFF64019069109@GANDALF>

Hello everyone:

Some of you may know that many moons ago we (Brian) developed a plug-in
for Netscape Enterprise Server (ES) 2.x (and FastTrack -- based on the
same libraries) that addressed Netscape's nasty habit of removing
authenticated_user information from the environment before calling CGI
apps.  Obviously, this has a deleterious effect on interesting zope
applications.

Fortunately (?), we are up to our armpits in projects and initiatives.
As a result, we need someone to do a bit of work to upgrade the plug-in
from ES 2.x to ES 3.5.x.  I can provide the following files from our 2.x
incarnation:

o  plug-in source code
o  obj.conf
o  magnus.conf

The source code is only 153 lines of generously formatted C (w/lots of
defs) so I'm hopeful that this isn't a HUGE task.  I'm interested in
hearing quotes from people in the community that have experience with
the NSAPI and would, for a reasonable fee, develop, compile (Solaris 2.6
and NT4) and test an upgraded plug-in.  The work would be contributed
back under the ZPL.

Naturally, I'd also entertain offers from people to do this for free!
:^)

--Rob

P.S. - I KNOW there are some NSAPI wizards out there so don't be shy!

How about Mr. Creosote. This is a wonderful little utility from Jeff
Bauer. It basically an example implementation of socket datagrams... ie.
it lets you print out via a socket to a little server program. Its great
for debugging Zope/Bobo apps.

Here's Mr. Creosote's web page for more info...

Please don't ge me wrong:  I _like_ ExternalMethod / Product as a way to extend
Zope.  My comment is in the context of not (currently) being able to add
ExternalMethods to my Zope demesne on starship, given the (quite legitimate)
security concerns of the Zopemeister.

I looked at the ExternalMethod source last night a bit:  the actual method
execution is done via an apply() call, after loading and compiling the code for
the function.  We might be able to come up with an alternate product which used
a carefully tuned rexec() (Bastion?  I plead ignorance), operating on Python
code stored in the Zbase itself.

The particulars of my case are that the control structures of DTML are not quite
powerful enough to accomplish my task;  of course, strengthening them, even in a
"sandbox" model, still leaves open the possibility for buggy/malicious code to
do ugly things (like your example below).

Any Turing machine can do "while 1: pass", so no sufficiently general syntax is
"safe" from this attack.

Actually, the possibility which seemed most interesting was Doug Wyatt's
suggestion of "federating" a set of independent Zbases under one (at least
apparently one) server.  Then any damage my ExternalMethod did would be to the
Zbase would be on my own head, at least.  If that server were actually a process
running as me, then standard system security procedures should probably be fine.

You might want to consider switching to one of the official binary kits
available from MySQL's homepage. MySQL is notoriously picky about how it
is compiled.

Looks like you didn't install the development libraries for python
(python-devel or python-dev).

This was an idea I'd proffered, but honestly haven't looked at enough
yet to know whether it would work... it SHOULD work, but it might
require some modifications to the aquisition code, but I've not looked

Well, it might help if you offered what control strucuture you need, we

TO me this is just a hack to get around it near term, and doesn't fix
the problem.  Also if you have 100 users, do you have 100 instances of
zope running under 1 ZServer?  That sounds like a true administrative
nightmare...  And substantial overkill.

Ok, the "teeth-cutting" example I am trying to implement generates math-facts
problems for my five year old.  In Python, two trivial functions:


I _think_ this one is easy in DTML:

    def problem( max_term, operators ) :
        """ Generate a single math-fact problem whose terms are within
            range( max_term + 1 ), using one of the supplied operators.
        """
        lhs = random.randrange( max_term + 1 )
        rhs = random.randrange( max_term + 1 )
        operation = operators[ random.randrange( len( operators ) ) ]
        return ( lhs, operation, rhs )

But not this one:

    def gen_problem( max_term, operators ) :
        """ Generate a math-fact problem whose terms and results are all within
            range( max_term ), using the supplied operators.
        """

        while 1 : # Arbitrary looping! (could benefit from
                  #   the dreaded assignment-in-conditional :)

            probStr = "%d %s %d" % problem( max_term, operators )
            result = eval( probStr )

            if 0 <= result and result <= max_term :
                return probStr

And of course, the DTML syntax for something like this is going to be ugly.

One instance per "sandbox", not one per user (although on starship this is a
distinction without a difference).  The "content manager only" applications will
do fine in a single Zope instance, as now.

In my experience many situations where external methods are needed do not
require access to the Zope data tree, like the math test example you
presented. 

One approach is to use a second server that does XML-RPC (Fredrik Lundh
has already written a client and a simple server) and set an
account/folder where everybody can upload their scripts and access them
through XML-RPC calls from their Zope environment. I suppose we can write
a product that provides the client site of the XML-RPC based on Fredrik's
implementation. As for the server site Jim once mentioned that the support
should go in ZPublisher but initially a simple server based on python
standard libraries will be adequate. Or use the newly released asyncore
libs though I suspect a multithreading server will be better in this
situation.

If however one requires access to the 'self' argument of an external
method such an approach will not be adequate. Usually though one can
collect the relevant parameters by using DTML calls and send them to the
XML-RPC server for processing.

Suggestion: for python-python data transfer and storage
XML-RPC is overkill.  Python already has marshal which will
be a lot faster and I think do the same thing.  Also, if you
haven't, please have a look at what I did using gadfly and cgi.
I know it's more conventional and hence boring, but nevertheless...

Message-ID: <016401be64f3$2e5b79d0$8725d2d1@rogue.jenkon-dev.com>

I have a folder with various boolean properties associated with it which are
accessed by the dtml docs as flags for enabling or disabling content.  Turn
off the flag and a chunk of the page goes away when it is next viewed.  This
works great, but I would like to associate that behaviour with the security
attributes.  In other words, when somebody in the Anonymous role is viewing
objects in the folder the properties should be unset, but when users in the
manager (or some other specific role) view the pages then the properties
should be set and those parts of the pages are activated.

How can this be done?

Thank you, Martijn, you've made my day!  This is extremely cool.  

As you might expect, here at digicool we're yearning to produce more and

from anyone else who can help, is *severely* appreciated.  I know i'll

Some thoughts:

 - We would be happy to provide a mailing list or two for you all

 - If it makes sense (logistically, for us as well as for you), we could
host 
   the FAQ stuff or whatever on zope.org.  This we'll have to discuss -
both
   what all might want, and what we can safely and effectively do...

(I've been thinking about requirements for a collaborative FAQ
mechanism, which can be tricky if you want it to be available for
contribution to the community in general, yet still remain organized
enough for people to find what they're seeking.  An interesting
problem...)

For those interested changing the "chunks=1" to "chunks=0" in
http_server.py did in fact fix the incompatibility with MSIE and ZServer.

Zope's, I don't consider this a bug with ZServer but with MSIE as this also
plauged me using Frontier cgi's many times, the fix was the same. So I'm
not creating a bug report unless you want this documented.

Oops! The a.b_id=a.id was a typo in my mail. Sorry about that. I did
mean a.b_id=b.id.
I also tried out Brad Clements' suggestion (thanks, I would have never
thought to write it that way!) but it raises the same exception. It
works fine with the patch, though.

Thank you for your responses!

Hm - this indicates you've upgraded your Python since the module
_pg was compiled (postgres?)
It's not the cause of the following error, but it is something you might
want to fix, anyway.

The error looks to be caused by ZopeHTTPServer not handling a client
aborting the connection. Looking into the code, at around line 240 of
ZopeHTTPServer/ZopeHTTPServer.py, the write() method of ResponseWriter
should probably trap IOError and ignore it. 
Something like wrapping the two calls to write() in the write method
like
  try:
      write....
  except IOError:
      pass

would be a blunt fix to it. I don't think DC want to continue to 
support ZopeHTTPServer, tho. You might want to try to upgrade to ZServer,
instead.

No, because from DTML you can't call methods starting with an underscore. This
was actually the reason I didn't include this in my overview.

You can still use it in en external method, I know. But then again, I can do a
heck of a lot more bad things in external methods.

This is very hard to do from the serverside. I can force a new login, but I
cannot stop a browser from authenticating itself at every request, therefore
effectivly becoming anonymous.

Problem is more that HTTP is stateless, a user is not 'still logged in', but it
autenticates itself at every request. Only when the server says that the
authentication is incorrect, does the browser ask for the username and
password.

What you could do, is write your own UserFolder/User combo, that stores a
last-access time on the User object, and checks for this every time a user is
authenticated. If the difference is greater than, say 15 minutes, you force a
reauthentication by raising a permission denied.

I tried playing with this once upon a time, but I found that the stupid
browser still cached the original result and would continue to use it after
the failed login/relogin combination. Most frustrating.

Subject: [Zope] need help with IIS/ODBC
Message-ID: <3.0.6.32.19990304173128.008fc510@hito.eccosys.com>

As a novice (who's loving Zope!) I'm having a terrible time trying to get
Zope1.10.2 on NT with IIS to connect to MS SQL with a Z ODBC connection.
Previously I had no problem getting Zope 1.9/ZopeHTTPServer to connect to
MS SQL via Z ODBC. 

Recently I upgraded to 1.10.2 without a hitch, and was able to run it with
IIS 4.0 after putting the (PCGI executable?) MYZOPE.exe in
/InetPub/scripts/ and turning off in IIS both Basic Authentication and NT
Challenge/Response as I read here in the list.

My problem now is that when I try to open my db connection (exactly the
same connection that was working with 1.9 & ZopeHTTPServer) I get the
following error from IIS:

>HTTP Error 400
>400 Bad Request
>Due to malformed syntax, the request could not be understood by 
>the server. The client should not repeat the request without modifications.

In trying to figure out what's going on I've noticed a couple things.
First, and I think most illustrative, if I try to add a new Z ODBC
connection, none of my ODBC sources are showing up in the available list
(except the default 'LocalServer, SQL Server') - whereas if I run my 1.9
Zope with ZopeHTTPServer all my ODBC connections show up just fine.

Also, running my new 1.10.2 Zope/IIS with the faulty db connection side by
side with the functioning 1.9/ZopeHTTPServer, I printed our the environment
variables of both and noticed some differences - USERPROFILE's are Default
User vs. Administrator, and the 1.9/ZopeHTTPServer contains variables not
contained in the 1.10.2/IIS environ: HOMEPATH, TEMP, USERNAME, HOMEDRIVE,
USERDOMAIN, PROMPT, LOGONSERVER, TMP. I attempted to set at least
USERDOMAIN in the 1.10.2/IIS environ, with no luck.

I've read all the posts from the list that I could find dealing with IIS
and ODBC, but couldn't find anything with info on this type of trouble.
Have I made a boneheaded mistake and started to look in the wrong places
for the fix? Any help/info/pointers would be hugely appreciated as I
continue to bang my head on my keyboard hoping that I'll soon clear this
hurdle and get back to having fun with Zope!

Thanks!

Jay

You could, using AUTHENTICATED_USER.has_role() and manage_changeProperties(). I
think it will be better if you completely skip the property setting though..

You could just show content using
<!--#if ATHENTICATED_USER.has_role(['Anonymous'])-->
        Content _only_ for the Anonymous user
<!--#/if-->
<!--#if ATHENTICATED_USER.has_role(['Manager'])-->
        Content for users with the Manager role.
<!--#/if-->

This way you don't accidently let any properties float around, causing content
to be shown to the wrong people.

You can use the #in tag's grouping features for this. If you use GROUP BY in
your SELECT statement, or use the appropriate sorting, you can use the
following DTML code to get the desired output, assuming the column names are
the same as in your example:

<!--#in MySQLMethod sort=field2-->
<!--#if first-field2-->
    <!--#var field2 fmt="DayOfWeek"-->, 
    <!--#var field2 fmt="Month"-->
    <!--#var field2 fmt="day"--><BR>
    <BLOCKQUOTE>
<!--#/if-->

<!--#var field1-->

<!--#if last-field2-->
    </BLOCKQUOTE>
<!--#/if-->

<!--#else-->
Sorry, no colors in your query.
<!--#/in-->

The variables first-xxx and last-xxx are set whenever the field with name xxx
starts/ends in a sequence. For more information on this, read the Zope DTML
User's Guide (http://www.zope.org/Documentation/Guides/DTML

Subject: [Zope] ZPublisher and creating children
Message-ID: <36DCF9B5.97A62E66@acriter.com>

Hi,

I'm using ZPublisher+DocumentTemplate+BoboPOS in a cgi environment,
because that's all I need (and can use on my ISP's box). In the couple
of things I've developed so far, a pattern has emerged that disturbs me:
if you have a container object, when adding a child, the whole add thing
is done in the parent. IIIRC, I fetched this design from the (Bobo)
Trinkets example when I started:

class Container....
     add = HTMLFile(....)
     def do_add(self, childattrone, childattrtwo, childattrthree):
        d = self._items
        d[childattrone] = Child(childattrone, childattrtwo,
childattrthree)
        self._items = d

class Child...

     def __init__(self, childattrone, childattrtwo, childattrthree):
         ....

     edit = HTMLFile(....)
     def do_edit(self, childattrone, childattrtwo, childattrthree):
           ....

The Container, IMHO, "knows" too much about the Child in this case, and
it's hard to modify the attribute set of the Child class. Am I doing
something wrong? Is there a design pattern here I'm not aware of?

Regards,

Cees

I have exactly the same problem with an Access database, same error. I'll file

These are good ideas (and thanks Chris for the offer!), but Ken
Manheimer later on in the list is offering space on www.zope.org, and
that would of course be perfect.

It was getting obvious that this was so. You guys all did a great job,
and still are doing a great job, but the volume of questions and
documention requests has exploded in the mean time. Which is great, in
fact, of course, as it shows people are interested.

This would be great! We probably don't want to be spread out too much so
one mailing list would be best (zdp@zope.org?). I also intend to make
regular announcements of ZDP's progress (and some advertising to get
people more involved in the project) on the main Zope list (or future
multiple main Zope lists :).

Right now though to keep the ball rolling I'll be using the normal list
to send out messages.

Zope.org would I think be the ZDP's favorite place to be hosted on, so
that'd be very nice. Your thoughts on how we could best arrange this
(who gets manage access to the place, if we develop in a branch we
export to you, or develop in there directly, or use FTP, or possibly
something else, etc) are welcome.

Independently (for local purposes) I've been thinking about making a FAQ
wizard product myself, but I got stranded somewhere in the beginning (my
laments I posted some time ago to the list :). But at least I've given
some thought to the design. Now Amos made one, and we can build on that.

The use of the tree tag is nice, but probably a simple list is more
useful in some cases (one can do a text search in it, for instance).
From my cursory glance at the management screens of the example, it
seems that it's not hard to produce that.

What would also be nice is some way to simply generate plain ascii text
versions of the FAQ as well, along with possibly some other versions. We
could also think about generating DocBook SGML (which then can be
converted in a lot of different formats with for instance the Linux
SGMLtools 2.0).

I haven't given too much thought to collaboration mechanisms. It would
be useful to have the ability to easily move questions around in the
list from one section to the other. My plan is to early on just get any
question/answer pairs we can come up with (from mining the mailing list,
documentation, and whatever people contribute). Later on we can then
organize these in categories, once the pattern becomes clear (likely
we'd have a DMTL section, for instance, and an installation section). If
there's flexibility in moving questions around the FAQ might be
developed more quickly. 

People could contribute question/answer pairs (or just questions) in
some 'contribution area' and the managers of the list can then edit
these and move them to the right sections of the list after doing so.
The contribution area should still be visible for everybody, so that
even the raw entries can be useful. I'm brainstorming right now, so
here's another idea: if someone sees a question in the 'contributed'
area that he knows the answer to, that person should be able to write in
an answer. Even with the already edited questions in the main list it
would be useful if people could leave comments ("I tried this but it
didn't work for such and such reason. But if I did this and that, I got
it working."). The editors can then later review all that's added and
integrate it into the main text.

Right now I intend to just assemble a big raw plaintext file (structured
text!), though; anyone can work with these. It's good to keep the
process moving.

Martijn

I have no DNS, it's a local system only. I'm using Windows 95 and this
doesn't work. But it should no problem to "fix" the ftp_server. The
IP_ADDRESS could set in start.py and this address is used by the

Using the "in" tag's grouping capability, is there any way to get the count of

and a cell rowspanned for all the group's items (eg: related products and their

Message-ID: <01E40461E003D21195CC0080296495D80B12B3@gates.cdc-group.com>

While debugging a Product that inherits from OFS.Folder stumbled across
the following problem (copied from the debugger command line stopped
inside one of my Product's methods):

>>> self.__class__.__bases__[0].__bases__[3].__bases__[1]
<class OFS.CopySupport.CopySource at 8d11e0>

>>> isinstance (self, OFS.CopySupport.CopySource)
0

>>> (self.__class__.__bases__[0].__bases__[3].__bases__[1] 
     is OFS.CopySupport.CopySource)
1

The first line says self is an instance of OFS.CopySupport.CopySource,
the second says it's not. The class objects are identical.

My problem is that I'm not able to override one of 
OFS.CopySupport.CopySource's methods and to call the
base classes method from inside. At that point I get
a 
    TypeError: unbound method must be called with 
               class instance 1st argument

which usually occurs when calling an unbound method with
an instance of the wrong class.

I'm clueless..

No, there isn't. You will have to use the SQL statement, to add a calculated
value column to it's output. You should be able to use COUNT to achieve this.

Actually this example shows the beauty of Zope/Bobo programming -- the
code looks completely like normal Python code, no CGI hackery involved.

Anyway, this is really a Python question, IMO.  You don't the arguments
to the Child's constructor to be hardwired in the Parent, right?

You could take a route where pass a dictionary, e.g. REQUEST, into the
Child's constructor and let it figure out for itself what it needs.
This feels less OO and doesn't let Zope/Bobo help you with type
conversions and raising exceptions for missing arguments.

Good timing.  We are planning a Collector Day At The Beach pizza party
on Friday.  We'll gather everybody together for a couple of hours,
discuss a bunch of submitted issues, and try to clear them out.  I'll
articulate a policy on support within a week.

We still haven't emerged from our network hell -- our dedicated line
hasn't been installed yet -- but things are slowing getting under
control.

Count me in as well.  I'm meeting with some folks today to get a Zope
training course scheduled.  I'll create the preliminary docs which they
will improve and use for the course.  Thus I'll have some some material
for a (perhaps four day) training course to contribute.

BTW, is there any interest here in a Zope training course?

Subject: [Zope] [ZDP] Assorted FAQs
Message-ID: <36DD3FD7.F71EAE80@pop.vet.uu.nl>

Hi everybody,

Here is a start. I just randomly browsed the mailing list and created a
completely uncategorized set of questions and answers for the FAQ. I
even snuck in a question of myself, see if you can answer it. :)

If you see a problem with some of these questions or answers, send a
followup with suggested corrections to the list and I'll include them in
the FAQ. If you have more question/answer pairs, go ahead and followup
too. I prefer these things to appear in the list (in a thread, and
marked by [ZDP]) for now, as this might stop people from writing the
same FAQs twice. I hope in a while we'll get somekind of collaborative
FAQ environment going that makes all this easier.

I'd prefer additions to the FAQ in StructuredText for now. See what
follows for an example of the format I have in mind. If you think
another format works better feel free to convert. (yes, that's the theme
of open source; if you want something done differently, feel free to do
the work to change it :).

Here's what I have so far, enjoy!

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use:

        &lt!--#var "external_method_name(arguments)"--&gt
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is:

        &lt!--#var expr="external_method_name(arguments)"--&gt

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

Well, the underlying issue is the stateless-ness of the whole thing. In
normal python, you'd create an empty child, call the child's editing form
so the user can enter initial data, and only after the user's commit add
the child to the container:

def addChild(self):
     newChild = Child()
     if newChild.editForm() == true:
        container.append(newChild)

in short. I've attempted this in the ZPublisher environment, but to no
avail - either it didn't work at all or it got very messy (with the Child
needing to know about the Parent, etcetera).

I must say, I was under a bit of time pressure last night when looking for
alternatives (wanted to have a beta release on my website before
breakfast), I haven't got around playing with hidden form variables
etcetera yet - that could work. Just hoped somebody on the list here would
have a canned answer - I'm a lazy guy ;-)

Subject: [Zope] Some tough questions about zope... (long)
Message-ID: <v0410440eb302e9edd947@[128.240.198.13]>

Hi all,
This is quite a long email where I ask a lot of questions about Zope, 
but I hope you'll be lenient with me as I think I have a few hard 
decisions to make!

Some background:
I'm one of the web developers here, with a remit to implement a 
curriculum database that can;
(a) support the Medical Faculty here
(b) get rolled out to three other Medical-related sites, each with 
their own 'look and feel'
(c) possibly implement a University-wide curriculum database.

The curriculum database is essentially delivering online study guides 
(over 100 for each Faculty) whose source is originally from very well 
marked up Word Documents. In addition, we include multiple choice 
questions, file upload of lecture notes etc. and some 'active' web 
pages showing dynamical processes in medicine etc. The curriculum 
database needs to be searchable across its entire breadth (although 
initially restricted to the one site), so that students and faculty 
can find occurences of, say, 'lung cancer' in lecture resources - 
this is to plan for curriculum management, so that we can find out if 
we're pushing subjects too much (or indeed, whether we're pushing a 
subject at all!). We have other applications (nearly all of which are 
written in Perl/PHP3) and want to seemlessly integrate them into the 
curriculum database.

Currently we do all our development work on Unix, using Apache 
virtual web servers, MySQL as our database engine and Perl running as 
a CGI for most of our applications. My input has been to introduce 
PHP-3 (an Apache module with a bulit-in XML parser) and some XML 
knowledge to the group. I've been looking at a scenario where our 
study guides are converted in XML using Omnimark and held as static 
XML documents in a database. They are then rendered into HTML/RTF and 
put into static web directories. The student can run a program that 
extracts elements from selected XML documents and creates a 
customised set of HTML pages or RTF document that is built for them 
'on the fly'. My manager was a bit worried about all these static 
pages lying about and to be honest so am I, but extracting the 
relevant XML from a database to render into individual HTML pages 
seems a massive drain on the system.

I found out about Zope Monday morning, dl'ed it, installed it, got 
one or two things working... and have been worried sick ever since.

My problem? is that I can see how Zope can do so much for us, but it 
seems to need a hell of a gut-wrench to do so.
There also doesn't seem to be an easy 'half-way' house to move to Zope.
I've read a lot of the documentation, and am doing so constantly, but 
the wisdom of the list would be very helpful indeed.

The questions:
a) Is there a way for us to 'dump' the non-dynamic parts of a Zope 
database into static HTML pages. This would act as a way to say to 
the team "look, we have a parachute!".
b) Can I integrate with the Perl/PHP3 programs that we have (the Perl 
programs are mainly .cgi, but the PHP3 programs are server-side 
scripted, and as such are embedded into the HTML itself). This is so 
that I can
c) Is there any way of using the XML documents that I'm creating into 
the database and parsing them to produce either HTML or RTF output?
d) I know that this a terrible question to ask... but is Zope likely 
to 'remain' open-source (we're worried about getting stuck with a 
proprietary system)?.
e) Can I 'point' an Apache virtual server to run a Zope cgi (ie

Cookies or passing around secret messages would be the way to avoid
this, don't use Basic authentication at all.  The UserDB product shows
off a User Folder than uses cookies, and possibly today I am releasing a
User Folder product that authenticates off of a flat file, like
/etc/passwd for alpha testing which also uses either Basic or Cookie
auth.  If you use Cookie auth you are presented with a login/logout
screen to set/clear the cookie.

Thanks for the help, but...

My problem is a little bit harder than that. The data in field2 is date *and* 
time. So like this:

field1 field2
------ ---------------
red    3/1/99 10:00 AM
blue   3/1/99 11:00 AM
green  3/1/99 03:00 PM
brown  3/2/99 10:00 AM
yellow 3/2/99 04:30 PM

I've seen in the guide where you can format a data field when outputting, but 
how do actually extract the day-of-the-month number and put it in a temp 
variable. The pseudo-code I've used before to do this before is:

tempday = 0
for each record
  if tempday<>dayofmonth(datefield) then
     print out a header
  print out other fields
  tempday = dayofmonth(datefield)
next

I'm just having a little trouble translating that into DTML. Creating a simple 
temporary variable seems overly complicated.

This begs the question we've asked around here so many times, 'What is
data?'  Everything in Zope is Dynamic, in my thoughs, 'non-dynamic' is a
Document with not DTML in it.  But there is no way for Zope to sniff a
document and see if it contains dynamic structures or not.  Perhaps what
could be done is to write a simple MyDocument that you stipulate in
policy never to have dynamic stuff in it, and then write a crawler
scripts that sucks out all such documents into a local file structure.
There maybe easier solutions.

...do what? ;)  Zope can call your cgi scripts just like they are, as
URLs.  They would, of course, have to be external to Zope and if you
have a bunch of little ones you may find it better (and a damn sight
easier) to rewrite them as Python in Zope as external methods. (DTML is
also a rather powerful language for being so simple).  Just leave your
PHP stuff in your documents; Zope will parse out the DTML and return it
to the server, which will parse out the PHP stuff and return it to the
browser.  In fact, you can probably make DTML and PHP work together
nicely and simplify much of your PHP code.  In the quickie case you
don't need to change your PHP.

> c) Is there any way of using the XML documents that I'm creating into

Zope doesn't contain an XML parser.  You would need to do this with an
external package.

Yes.

Yes.

Yes.  There is an unsupported open source User Folder Product called
UserDB, where you tell it how to query your DB and it uses that for
authentication.

Not at all.

ooo.  Someone has yet to write an ExternalFile product (though I suspect
it would be fairly simple) to add objects to the db that refer to files
outside the db.  For now you can upload them as File objects to be
contained entirely in the db.  The same rules that apply to file name
conflicts in, say, a UNIX filesystem, apply to the Zope db.  You can't
have the same object id in the same folder. (With a minor non-exception
of aquisition, all lower folders can see the contents of higher folders,
but if you place an object in a lower folder with the same id as an
object in a higher folder the lower object will override the higher
object.  Get that?)

> i) Does Zope have the equivalent of 'server logs', which we

Since Zope is served through a web server you can continue to use the
server logs.  In other words, No. ;)  Object by Object logging is
something we've discussed, but would require *a lot* of thought and
work.

If that file is being served up by Apache then you can just use it's URL
as a 'pointer'.

Ah yes, the inevitable benchmarking question.  There are lots of issues
here, memory footprint vs processor speed vs concurrent access...etc.
The quick word is, Zope is fast and it will get much faster.  Zope is
currently not concurrent but will be in 2.0.  Zope+Apache is a bit slow
due to the pcgi bottleneck and is much improved by using ZServer.  As it
stands now, ZServer is something like twice to 10 times faster than
Zope+Apache.  Medusa (the web core of ZServer) serializes the requests
into Zope at the moment, but when 2.0 comes out it will be the fastest
web application platform on earth.  Don't quote me.

Let me try to answer (some) of your questions:

I will be looking into this, as soon as I have the time. The answer for now is:
probably, because everyone wants to download a local copy of part of any
website at some point. There are tools out there to do this, I haven't looked
for them yet.

>b) Can I integrate with the Perl/PHP3 programs that we have (the Perl

Just run Zope via Apache (see below).

>c) Is there any way of using the XML documents that I'm creating into 
>the database and parsing them to produce either HTML or RTF output?

Python is very capable of parsing XML. You will have to write an External
Method to handle this, though. An example of XML parsing can be found at
http://www.zope.org/Download/Contrib/XMLConfig.tar.gz. This Zope Product parses
a static XML file for use in Zope.

>d) I know that this a terrible question to ask... but is Zope likely

>proprietary system)?.

I certainly do hope so. I intent to use it en expand on it heavily anyway, and
sodo others. These extensions will generally be Open Source themselves, making
it hard for Digital Creations to pull Zope out of the Open Source domain.

>e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
>dropping the :port requirment).

Yes. The doc/WEBSERVER.txt will start you on this. Be warned though, there are
some problems with Apache and Zope integration, for reasons that others are
better equiped to explain.

>f) I'd like to have the option to have user authentication 
>information coming from a database - is this possible?

Yes, you can find the UserDB Product at
http://www.zope.org/Download/Prereleases/UserDB/UserDb-1.2.0-nonbin.tar.gz.

>g) We have something like 200 main level directories holding the

Nah, Zope has handled much more than that allready. Ask Paul =).

>h) We also need resources such as QuickTime movies, images PowerPoint 
>slides etc. to be uploaded - would they sit in the database or can

Zope can store any filetype you want it to. Filename conflicts are handled the
same way a filesystem handles them: In the same Folder, you cannot have two
objects with the same name at once. But because it is a hierachical system, you
can use the same name in two different folders.

>i) Does Zope have the equivalent of 'server logs', which we use for research.

ZopeHTTPServer's output is it's serverlog. You can start it up with STDOUT
redirected into a file. When you use Apache as your webserver, all requests
will be logged through Apache itself.

You said it yourself =).

Zope will be much much faster. I can't give you any direct numbers, maybe
someone else on this list can. You basicly don't have the overhead of starting
a fullblown new process for every request, and Zope pools Database connectiosn
for you, so you don't have the initial connection overhead either. And, your
code isn't compiled everytime, like with Perl.

| decisions to make!

I know the feeling. I was choosing between ColdFusion and Zope for
developing my new application and had some similar questions. Ultimately,
I chose Zope.

[nice application description deleted]

| a) Is there a way for us to 'dump' the non-dynamic parts of a Zope 
| database into static HTML pages. This would act as a way to say to 
| the team "look, we have a parachute!".

Right now, there isn't. This question has come up repeatedly on the list,
to the point where DC is getting sick of hearing it and thinking of actually
implementing something :)

They have said it would be pretty easy, and I believe it. I think 
the basic idea is to write a method that will go through the Folders and
use the DocumentTemplate code to render out the pages.

| b) Can I integrate with the Perl/PHP3 programs that we have (the Perl

| that I can

If you're using Zope with Apache, you use mod_rewrite to get the
authentication headers passed to Zope. You can also use mod_rewrite to
decide how URLs map to content on your server. For example, you can
have all of the content on your site go through your Zope.cgi, but
/cgi-bin/* can go directly to your CGI or PHP files. You can access
MySQL from Zope, PHP and Perl, so they can all use the same data
source for the databases.

| c) Is there any way of using the XML documents that I'm creating into 
| the database and parsing them to produce either HTML or RTF output?

I'll leave this one to people more knowledgeable about XML.

| d) I know that this a terrible question to ask... but is Zope likely 
| to 'remain' open-source (we're worried about getting stuck with a 
| proprietary system)?.

I think it would be tough for DC to try to take it back at this point :)
Even if DC did decide to not release any more updates to Zope, the community
would probably continue working from the 1.10.2 code. Anyhow, DC had
sound business reasons to release Zope as Open Source. Over time, they
will likely get a lot of benefits by having done so and by encouraging
outsiders (like us) to work with and improve Zope.

| e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
| dropping the :port requirment).

Yes. This uses a technique called Persistent CGI. It works quite well.
There is also a hope that there will be better integration with Apache
in the future. Also, as ZServer stabilizes, you may find good reason to
migrate from Apache to it.

| f) I'd like to have the option to have user authentication 
| information coming from a database - is this possible?

There is an unsupported bit of code called UserDB which is designed for
this.

| g) We have something like 200 main level directories holding the 
| study guides, each with up to 200 files in them - is that pushing the 
| Zope database too far?

Though I have no first hand experience with a Zope DB this large, the
DC guys have said that they've worked with some very large DBs.

| h) We also need resources such as QuickTime movies, images PowerPoint 
| slides etc. to be uploaded - would they sit in the database or can 
| they be held somewhere else (and what happens about file name 
| conflicts)?

You could put them in either place. There would probably be some
advantages to putting them in the database. For example, your standard
Zope security rules will apply to the downloading and updating of the
files.

| i) Does Zope have the equivalent of 'server logs', which we use for research.

I don't know about ZServer, but if you use Apache as your web server you
will be able to use your standard server logs.

| j) Is it possible to have a 'pointer' at a location in the Zope 
| database that will point to a 'real, honest to goodness' HTML file on 
| the server (ie something like a redirect..oops I think I may have 
| answered my own question)

Yes, you can do a redirect.

| and lastly
| k) What kind of loads have people put Zope under (10,000 +hits a day, 
| 100k?). We have one application which has 170 Medical Students 
| sitting in front of screens and clicking a button at the same time 
| (they're selecting their final year options) which then starts 170 
| CGI-based Perl processes off interrogating and updating the database. 
| This really grinds the system down...

I've heard it said that Zope should be able to handle 500k hits or more
on reasonable hardware. Of course, this depends on exactly what the
server has to go through for each of those hits, etc. DC is also working
on concurrency for Zope 2.0. This will probably enable you to handle a
whole bunch of requests.

Good luck!

You'll have to use SQL function for this. In MySQL you could do the following:
SELECT field1, DATE_FORMAT(field2, "W, M d") as datefield FROM MyDB.

Put this in a Z SQL Method, and then the following DTML will get you your
results:
<!--#in MySQLMethod sort=datefield-->
  <!--#if first-datefield-->
    <!--#var datefield-->, 
    <BLOCKQUOTE>
  <!--#/if-->

  <!--#var field1-->

  <!--#if last-datefield-->
    </BLOCKQUOTE>
  <!--#/if-->

<!--#else-->
  Sorry, no colors in your query.

Everybody on this list is lazy ;-)

This is my approach:
First define a Webobject class that every object needs to inherit. The
simplest could be just:

class WebObject:
	        
    def __init__(self,name):
        '''__init__(self,name)
        '''
        
        self.name=string.replace(name,' ','_')

    def _set_root(self,root_obj,parent_path):
        '''_set_root(self,root_obj,parent_path)

        sets the root object and relative path. Note: 
	one will never need to pass parent_path directly. I also need
	to have a reference to the root object so I can do stuff remotely
	similar to acquisition'''

        self.root=root_obj
        self.rel_path=parent_path+self.name+os.sep

class Container(WebObject):

    def __init__(self,name):
        WebObject.__init__(self,name)
        ##Holds contents
        self._d={}

    def __getitem__(self, key): return self._d[key]

    def items(self): return self._d.items()

    def _do_add(self,object):
        '''_do_add(self,object)

        Adds object in container. Object MUST have inherited the
        WebObject class.'''

        name=object.name
        if hasattr(self,name) or self._d.has_key(name):
            raise ValueError,'Object with same name exists in WebFolder'
        d=self._d
        object._set_root(self.root,self.rel_path)

        d[name]=object
        self._d=d

So you can create any object that has inherited the WebObject class
independently and add it to the container instance.

Subject: [Zope] [ZDP] Tree FAQs
In-Reply-To: <36DD3FD7.F71EAE80@pop.vet.uu.nl>
Message-ID: <4.1.19990303153836.00a64c50@lisp.atmm.nl>

My two cents on the tree tag:

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute of
    the tree tag. The objectValues function of a folder returns all objects
    contained by that folder. 

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML 
    Document objects in a Folder. Other metatypes you could select on are:
    Folder, DTML Method, File, Image, Mail Host, User Folder and Session.
    This is not a complete list, as Products can and will define their own
    metatypes. If you want to show more types, just add them to the list,
    like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        &lt;!--#tree branches_expr="objectValues(['Folder'])"--&gt;
	    &lt;A HREF="&lt;!--#var URL1--&gt;/&lt;!--#var id--&gt;"&gt;
            &lt;!--#var title_or_id--&gt;
            &lt;/A&gt;
	&lt;!--#/tree--&gt;

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a tree, is
    called with ?expand_all=1, the tree tag will expand all it's branches.
    Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand 'buttons'::

        &lt;A HREF="&lt;!--#var URL0--&gt;?expand_all=1"&gt;
          Expand all&lt;/A&gt;|
        &lt;A HREF="&lt;!--#var URL0--&gt;?collapse_all=1"&gt;
          Collapse all&lt;/A&gt;

        &lt;!--#tree--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        &lt;!--#tree single--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;


More cents will follow.

Great start!

Could I suggest that there be FAQs for different catagories?

My list would include:

DTML
external methods
Win32 (maybe there are specific issues, if so I don't want to read about
them :)
SQL methods
patches/hacks to Zope

I am sure that I can find lots of work for you!

This sounds like something we need.
I know that I could use it.
If folks will critique this design, I'll implement it.

- - Proposed Access Method - -
It is desired to be able to have "non DTML" files incorporated
in a Zope URL system. These files might be static GIF files,
quicktime movies, or just plain old HTML.

Obviously, they might be "included" in a DTML page by simply
referencing them directly by their URL. However, I can see cases
where one would like the access to be under the control of the Zope
system.

For example, access controls might apply.

I believe that we can achieve this by having an object
which represents an ExternalFS mount point.

In general, we map a URL onto a node of the FS.
It would be directly analogous to a symbolic link (ln -s).

The Zope mount point would enforce permissions just as if the
file were loaded into the Zope DB.

Objects can be "imported" without having them take up space
in the database. Their creation and maintanence can be handled
outside the Zope system.

They are rendered by "cat"ing their contents.

By permitting substitutions in the link, we can create effective
reformatting of the visible FS.

As an example, I am monitoring customer traffic. "mrtg" automatically
generates graphs for each customer.

In Zope, I could create customized displays by importing these files.

By using the ExFS, I can update the graphics without affecting Zope.

Further, assuming
 /mygraphs/today/customer1.gif
 /mygraphs/today/customer2.gif
 /mygraphs/yesterday/customer1.gif
 /mygraphs/yesterday/customer2.gif 

we can map them onto

somewhere/KustomerA/graphs/today
somewhere/KustomerA/graphs/yesterday


by substituting a property of the Kustomer

Thoughts and/or suggestions?

Time to move this to zope-dev?

anyway, I think this sounds like a good idea. It harkens back to an 
inquiry I made about byte-serving PDF files. I don't want to dump my 
pdf's into the database.

If you can implement this, I think I could implement byte-serving.

Although byte-serve could be handled at the ZServer level, I think for 
large external files it'd be more effective at the "cat" level

This is a good idea. I can see this FAQ growing very, very quickly.
So, I would suggest that we start thinking about a hierarchy
already... a couple suggestions below:

| 

Installation
* building
  * win32

  * ZServer

How safe would it be, to allow any random user to use the add menu to create
arbitrary symlinks into the native file system tree?

Rather than using rowspan, use nested tables. I haven't done this in
Zope yet, but it was always my solution of choice in ColdFusion. It also
makes it easier to debug your layout in a WYSIWYG editor. It does, of
course, bloat your HTML a bit.

It will work, and I'm going to have to in the short term, but I really would
like the multiple columns for each item to line up down the page, without ugly
fixed-width hacks.

Maybe by splitting up the FAQs we could split up the work, too! Have a
different person/group resposible for each FAQ.

Of course there would be nothing stopping some energetic type being
involved with all of them :)

Also, I think that HOWTOs of the Linux type would be a great idea. They
have a person/group responsible for each HOWTO to keep it up to date and
add/edit things as needed.

I am just commenting from the sidelines. Right now I barely have time to
scan through the zope-list!

Well, I think it'd be nice if there was someone "responsible" for each

You can find a "howto" LaTeX stylesheet in the Python CVS checkout, and
I'm sure Guido/Fred wouldn't mind us using this.  It works real well,
and can target HTML, ASCII (I think), Postscript, PDF, etc... this lets
you do the "bigger" stuff in a nice pretty way. 

What would also be nice is a list of "bigger" issues that people would
liek to see explained more... something that's more than a single
question.

Ok, I found:
http://www.python.org/doc/howto/writing.html
the link on that page:
you can grab [Fred Drake's documentation 
distribution], and use...
Is broken with a "Error 404: File Not Found"
Searching for "LaTeX CVS" didn't quite get it
can you please provide the links?

Not only will this be good for the DOC project
but also for general use in targeting HTML
PDF etc....etc...

Subject: [Zope] etcUserFolder Product
Message-ID: <613145F79272D211914B0020AFF6401907BACC@GANDALF>

Greetings,

(This is crossposted because it is a product anouncement, and contains
interesting developer pointers)

I've have massaged the source code for UserDb and created a new user
folder products called etcUserFolder.  This products authenticates off
of a flat file of usernames:cryptedpasswords.  If there is anything
trailing the crypted password it is ignored, so any /etc/passwd file
will work.  It is generaly not recommended, however, to use your
/etc/passwd file for security reasons.

This is an unsuported product and has been written because it was asked
for a few times, and I felt the community could use another good example
of writing user folders.  It also shows off cookie authentication which
Brian perfected with UserDb.  Here is the documentation:

etcUserFolder requires a directory called 'etcUsers' in which to place
your file containing the uid:pwd pairs.  This directory may be an
INSTANCE_HOME (typicaly your top level Zope dir), SOFTWARE_HOME
(typicaly 'lib/python') or in the etcUserFolder directory.  Jim wrote a
nifty function called getPath that sniffs all of these places for a
directory and file of your choosing.  This function is included in
etcUserFolder and will be included as a standard function of the next
release.  Other Product authors may find it interesting.

Since the flat file is meant to be b/w compatable with /etc/passwd and
htpasswd style files, there is no Role associated with the users it
authenticates.  You can specify a default role which is, by default,
'etcUser'.

I have not done extensive testing of this, therefore it is a

Subject: [Zope] DTML Method vs Document
Message-ID: <v04003a03b3034df988d1@[192.168.1.190]>

I just upgraded to 1.10.2 and I noticed that when creating a new document I
have a choice of DTML document and DTML method. This seems useful. I
noticed that all my DTML documents and DTML methods have the icon for a
DTML method. Everything seems to work.

What is the difference between a DTML document and a DTML method? Seems to
me a method should not be surfable but they are.

Is it possible to change my documents to DTML documents? Even just for
housekeeping.

One other unrelated question: What is a Principia Draft?

I just had a quick exchange with Fred Drake (who handles most of the
documentation duties for the Python organization), and he is aware of
this problem, and has forwarded the issue to AMK who is responsible for
teh HOWTO stuff.  IN the mean time, he suggests grabbing the latex
documentation whihc will have it all in it.  If this is too painful, I
can post a snapshot of the pieces taht are needed from the current CVS
repository.

The URL for the LaTeX documentation is:

I would love to see this feature (generating DocBook SGML). I thought
about something like this myself (for my howto), but I just don't have the
time at the moment. I could probably find enough time to help out a little
though.

Message-ID: <36DDA463.683D9460@avalongroup.net>

Hi,

I'm playing with Zope, and have been trying to get Zope to talk to MySQL
using the MySQLDA.

I'm running RedHat 5.2

Since there were caveats about having MySQL development enabled, and
such, I downloaded the source distribution for MySQL and made it. It
appears to be working very nicely.

When I follow the procedures outlined in the README, the following
happens:

I run make -f Makefile.pre.in boot and everything works correctly.

I then run make and get the following error.
gcc -fPIC -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5
-DHAVE_CONFIG
_H  -I/usr/local/mysql/include -I/usr/include/mysql -c ./MySQLmodule.c
./MySQLmodule.c: In function `pythonify_row':
./MySQLmodule.c:238: warning: assignment from incompatible pointer type
gcc -shared  MySQLmodule.o  -L/usr/local/mysql/lib -L/usr/lib/mysql
-lmysqlclien
t -lm -o MySQLmodule.so
ld: cannot open -lmysqlclient: No such file or directory
make: *** [MySQLmodule.so] Error 1

I did a locate on mysqlclient, and coudln't find the file. though I did
find some called libmysqlclient. So I changed the both Setup and
Setup.in to reflect that other name. however, I still get the above
error.

Any help would be greatly appreciated.

Your problem wasn't with the library, -lmysqlclient refers to
libmysqlclient (think of the -l as short for lib). The problem probably
was that libmysqlclient wasn't on the path gcc searched for libraries.
This is controled by the -L argument (-L is library paths). 

So... here's what to do:

1. Get everything cleaned up (ie. back in the condition after first
   untarring ZMySQL).
2. Edit Setup.in, add -L<the path to libmysqlclient> to the end of the
   last line.
3. Proceed as usual (make -f Makefile.pre.in boot; make)

If this would work (having Apache parse the PHP code in the pages returned by Zope), you would save me a lot of painfull converting working PHP code (mainly database related) and I would gradually convert from PHP/Apache to Zope/Python/Apache.

Pleaz tell me how this neat trick is done... (maybe some fiddling with the headers???)

Hint:
Creating a DTML Document/method with the following contents doesn't fool Apache in rendering PHP!

<!--#var standard_html_header-->
<h2>Give me the (PHP) money...</h2>
Read the phpinfo between the lines... NOT!!
<hr>
<? phpinfo(); ?>
<hr>
<!--#var standard_html_footer-->

This is my take on the situation.  As far as I can tell this is pretty
deep voodoo.

A DTML Method is what used to be just a Document in pre 1.10 releases.
DTML Methods are not objects, they are methods.  If you have a folder
called foo, and it contained a DTML Method called bar, then bar is a
method of foo.  foo doesn't contain the object bar, it has the method
bar bound to it.  What this means is that from bar's point of view,
'self' is a Folder object, and any properties it sees are properties of
foo, not itself.

DTML Documents are Zope Objects.  Their idea of 'self' is themselves.
They are contained in folders, but are not methods bound to that folder,
they are instances of DTMLDocument.DTMLDocument.  They can manage their
own Properties (because they inherit PropertyManager.PropertyManager).

Both DTML Documents and DTML Methods can hold DTML and content.  The
difference is subtle.  DTML Methods would be used when the answer to the
question 'Am I showing some other objects content through me?' is Yes.
DTML Documents should be used when the answer to the question 'Am I the
content I want to display?' is Yes.  DTML Methods have the advantage
that they don't have any properties, and their perspective of aquisition
is from their containing folders point of view.  DTML Documents have
properties which may interfere with aquisition you'd want to do, and
aquisition is from their own point of view, which may not be what you
want.

(BTW Martijn, perhaps the above should go in the FAQs)

If this isn't clear to you don't worry, it isn't even really clear to
me.  There is no way, but there really should be a way to convert
between the two because the roles for a DTML widget may change from
Method to Document as your system evolves.  This will probably be a
feature in the next release.

(This is the answer to the question 'Can I convert between DTML Meths
and DTML Docs?' for the FAQs)

You almost made it ;=)
The -lmysqlclient does refer to the libmysqlclient you found, but you should only modify the path pointing to it. This is done in the Setp[.in] just before the -lmysqlclient; modify the '-L/<path-to-the-libmysqlclient>', if have this set to -L/usr/local/lib/mysql.

[ZDP] Maybe this is something for the FAQ?

This can't be done currently. I researched this a while back, trying to
get server side includes to work. There's actually an entry in the Apache
FAQ about it:

"""
9.How can I have my script output parsed? 

     So you want to include SSI directives in the output from your CGI
     script, but can't figure out how to do it? The short answer is "you
     can't." This is potentially a security liability and, more
     importantly, it can not be cleanly implemented under the current
     server API. The best workaround is for your script itself to do what
     the SSIs would be doing. After all, it's generating the rest of the
     content. 

     This is a feature The Apache Group hopes to add in the next major
     release after 1.3. 
"""

Though this is about SSI, it basically means (I believe) that apache can't
take back the output of a CGI for additional module handling.

Hi  Sture,
try to use the P MySQL Input wizard in the contrib download area. It
will automatically create a insert sql method and a form for you. So you
can just follow the pattern.

I'm piggy backing this on Amos's post from a while ago, because that is
where I finally found my answer. I could have sworn I had seen (and
used!) a DTML code fragment that displayed the form variables sent to
it, with there values. Obviously, this involves indirection. 

After hunting through my (extensive) zope-list archive, I couldn't find
it, so I started over, with the help of Amos's text and wrote one. I
often need little tools like this to debug between my forms and sql
actions, so I can see what's really going on!

I call it 'show_vars'

The only tricky thing in it is that sequence-item is an invalid variable
name, so I need to wrap it in _[''] which leads to the double wrap when
dereferencing to get the value. Anyway, hope someone else finds it
useful!

I haven't tried it, but it could possibly be done by running two
Apaches: one which stands "in front of" the other.  The front-side
Apache would rewrite every access into a PHP wrapper-script which
include()s a corresponding URL from the back-side Apache where the
Zope things would be done.


On the other hand, I really should be asleep now so all this _may_
be utter nonsense, but I do think it's possible.  It may even be
possible with a single Apache, but that's more hairy than I dare think
about right now.  Good night.

(Btw, my suggested hack isn't in total disagreement with the quoted 
FAQ entry, because my hack surely won't work with SSI.  PHP3 isn't an
official Apache module, so they don't neccessarily mention things like
this in their FAQ.)

In all the world you might find 4 machines still plugged in that
support 'record' or 'page' structure.  The default is 'file', which is
what that command is trying to do.

Add these two methods to ftp_server.py::ftp_channel

    def cmd_stru (self, line):
        'obsolete - set file transfer structure'
        if line[1] in 'fF':
            # f == 'file'
            self.respond ('200 STRU F Ok')
        else:
            self.respond ('504 Unimplemented STRU type')

    def cmd_mode (self, line):
        'obsolete - set file transfer mode'
        if line[1] in 'sS':
            # f == 'file'
            self.respond ('200 MODE S Ok')
        else:
            self.respond ('502 Unimplemented MODE type')


And that should do the trick.

Micheal answered these perfectly.

>One other unrelated question: What is a Principia Draft?

It is a special use of the session object, but it appears to be partially
broken. When you create a Principia Draft, it asks you to specify an
orginal object, from the same Folder you are creating the Draft in. This
will be your 'draft', on which you can make changes invisible to the
outside world.

The draft contains an invisible Session object that is immediatly started
and joined, and an invisible UserFolder to facilitate extra users (for
example, customers that want to be able to view your work on it as well,
but have no access to it otherwise).

The Principia Draft suffers two problems however. The first is really a
Session object bug, in that security for Session objects is broken. This
has allready been reported as a bug to the Collector by me. The second
problem is that the Userfolder and Session controls are inaccessible via
the management screens.

The latter problem is caused by convention changes in the Folder object (or
the ObjectManager class really, used by Folder. I think that Folder objects
_used_ to call title_and_id on a object when displaying it in it's
management screen, but the current release of Zope constructs the id and
title of an object by using it's id and title separetly. Principia Drafts
made use of the call to title_and_id to insert links to its UserFolder and
Session controls. As this now doesn't happen anymore, you will have to do
this yourself.

As long as you have access to Session objects, you can change users on a
Principia Draft object by calling it's users__draft__.manage_main method,
and reach the Session controls by calling its manage_approve__draft__
method. The URLS are:
http://yoursever.com/Zope/Draft/users__draft__/manage_main and
http://yoursever.com/Zope/Draft/manage_approve__draft__

   As far as I understand there are DTML objects (templates), Products and
External methods. There is no such thing as "Internal" methods (objects,
that live in Zope's object database). Are these 3 the only 3 kinds of
executable (callable) things?

    By using the #in tag, you can easily all show all data in any dictionary
    object, like REQUEST.form, REQUEST.cookies and even REQUEST itself. Just
    call the items() method of the dictionary, and the #in tag will provide
    a sequence-key and sequence-item variable for every item in the
    dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>
        <!--#/in-->

    Use REQUEST.cookies.items() for all your cookies, and REQUEST.items()
    for all REQUEST variables, including CGI Environment variables.

I'm randomly assuming here you know more about DocBook SGML than I do,
so here I'm involuntarily inofficially  but you can back out of it
immediately appointing you the ZDP DocBook SGML expert. :)

I think perhaps the first thing you could do is get together with people
in the Latex thread for docs; they seem to have come up with it
independently. I know even less Latex than SGML and SGML seems a closer
fit with the XML-ish direction the web's taking, so my question would be
to point out the advantages of SGML to everybody.

Yup, splitting up the FAQ into different categories appears to be pretty
needed, so this is a good idea. My idea is to 'involunteer' you category
maker guys to take the assembled FAQ that I'll produce hopefully today
(in a few hours), and put each question in the category you feel it
belongs to. This way I have to do less work and thinking. :)

Subject: [Zope] Bobo or ZPublisher and stdout ( Solution: Client/Server)
Message-ID: <36DE5733.60F87988@oi42.kwu.siemens.de>

Hi,

I already sent some postings to this topic, but I would like
to discuss the following problem again and how it could be solved.

Imagine there is a big C++/Python project.
The application is mainly prgrammed in C/C++ und one supports
a scritpting interface to that application via the SWIG mechanism -
the target language is Python.

During the developping process many stuff is written to the stdout -
during initialization ( before the main-function ), during execution (
in the main-function ),
and in the destructors of the static instances ( after the main-function
).

Now we want to do some web-stuff via ZPublisher, we define
a function which return a html string, which is calculated through
calling functions
from our scritpting interface of our application, that means beside my
correct
calculated string there is many stuff sent to stdout, that confuses
the Xserver and I get an error.

Ok, you would say switch the stdout to a file via calling c-funcions
like dup() or dup2( ) and
encapsulate this in a function (wrapped via SWIG), which is called in
the function which I call from
the URL in the browser.

Less cryptic:

 xy.py:

   start():
       "XXXXXXX"

        #Now all stdout goes in a file
       stdout2file( "log.txt")

        ....
       HTMLstring = ....

        # sitches the stdout back ( REVerse )
        # The way is free for CGI
        REVstdout2file()

        return HTMLstring


the URL:    http://myserver:3333/yyy/cgi-bin/xy/start

BUT with this method I have no chance to chatch stuff which is written
to the stdout
in the destrutors of the static instances, because we already have
switched back to the
"usual" stdout (for a correctly working cgi-mechnism).
The some problem one have with things which are written
to the stdout during the initialisation of the static instances.
( Imagine python itself is compiled
against a library which writes some stuff to stdout during
initialization).

I see only one solution:
If there is a ZPublisher Server process which says to a client process
do everything
and give me a calculated string via sockets or something like that, I
have not to take
care about stuff which is written to the stdout at the client process.

Or are there better solutions ?

   Thanks in advance,

    Armin

Yes, this would be a good idea. My first priority however is to get as
much of a FAQ as possible out there. Organization we'll do at the same
time. Otherwise we run the risk getting bogged down in organizing who
does what. 

That said, volunteers who want to manage specific sections of the FAQ
are very welcome to step forward. Procedure is as follows: you get to
name your topic; the first person who names a particular topic and
produces a FAQ for it (assembling it from the FAQ we have now, and
hopefully adding more of his or her own to it) will be manager for that
section, unless that person doesn't want to, of course. :)

I suggest to mail this list instead of me personally, so that other
people can respond friday and during the weekend, when I won't be around
to check the mail. We're working on getting a zdp@zope.org mailing list
too, but I can't say yet when that'll be ready.

Aren't there some HOWTOs out there already on the Zope site? (there are
FAQs too but that doesn't stop us of course). HOWTOs and FAQs of course
have some overlap; we'll just see how it evolves.

Earlier I suggested using SGML Docbook for this purpose; I've appointed
John Eikenberry (without any feedback from him :) as our official SGML

HI all
I am a color specialist with Xerox. What i am doing with Zope is setting up
a Knowedge database for my fellow color specialist. I am having a bit of a
problem setting up a search query. Following is what i have know, Could
somebody tell me how i could improve on this query.

SELECT * FROM problems WHERE

problems_rip_model LIKE <!--#sqlvar dfe type=string optional-->
OR
problems.prob_descript LIKE '%<!--#var Problems-->%'
OR
problems.prob_solution LIKE '%<!--#var Problems-->%'

Is this the proper code or is there a better way of doing it?

Thank You

My rough sketch right now is a four-day course:

Day One -- Zope for Content Managers
Day Two -- Zope Programming Using Zope
Day Three -- Zope Programming Using Python
Day Four -- Relational Databases and Zope
         -- Zope for System Administrators

It would be a professionally produced and delivered "in the classroom"
class, a la Learning Tree.

That is, I won't be doing it. :^)  Instead, I'll produce a poor version
of the whole thing and give it to them, including the first customer
that will send maybe 7 people.  My poor version would probably become an
online version.

Just my thoughts currently.

I guess this counts as an announcement. Ken asked me to do it, but I
just mailed him I'd rather he did it (as he knows more about these

Hi everybody,

Here is the new ad-hoc FAQ. I'll start versioning it as of now; this

decide on, but at least we have a way to refer to this one now.

Note on the use of the Zope mailing lists:

    The Zope Documentation Project is getting its own mailing list
    (zdp@zope.org). In an attempt to gain publicity and support among
    the Zope community, I'll post this development FAQ to the main
    Zope list as well, however. Feel free to respond to it on either
    list for now, but you are encouraged to join the ZDP mailing list
    and to send new FAQ suggestions there.

    You can subscribe to the ZDP mailing list by using the page:

        http://www.zope.org/mailman/listinfo/zdp

Note on the categorizing of this FAQ:

    This FAQ is a FAQ in progress. It is uncompletely unstructured,
    unrelated questions are mixed haphazardly. If you feel the calling
    to categorize the FAQ or to maintain the questions for a
    particular topic, feel free to mail your changes to the list, and
    thanks in advance!

Note on the code examples and StructuredText:

    I've reconsidered and used normal '<' and '>' characters in sample
    DTML, for the reason that at least the FAQ is readable as text
    then. If you try to feed this FAQ through::
     
        <!--#var faq.stx fmt="structured-text"-->

    there will be an error message in Zope, however. For some reason
    Zope seems to try to interprete even StructuredText that uses &amp
    escape codes. Until this issue is resolved it is not possible to
    render this document into HTML.

    In my uninformed opinion, StructuredText code examples shouldn't
    be interpreted by Zope as actual DTML. There may be some rather
    subtle technical difficulties involved however. Any input on this
    is very welcome. Until the matter is resolved, the FAQ document
    will use StructuredText in the plaintext readable way.

    Thanks to Martijn Pieters in being so considerate to supply HTML
    escaped DTML examples; it's unfortunate his efforts weren't useful
    this time.

Note on my availability:
    
    Martijn Faassen (me!), ad-hoc FAQ maintainer of the ZDP's Zope FAQ

    something for the ZDP (such as editing and extending the FAQ) does
    not have to wait for Martijn to read his mail, having all relevant
    information available on the list.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like REQUEST.form, REQUEST.cookies and even
    REQUEST itself. Just call the items() method of the dictionary,
    and the #in tag will provide a sequence-key and sequence-item
    variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>
        <!--#/in-->

    Use REQUEST.cookies.items() for all your cookies, and
    REQUEST.items() for all REQUEST variables, including CGI
    Environment variables.

* What is a Principia Draft?

    It is a special use of the session object, but it appears to be
    partially broken. When you create a Principia Draft, it asks you
    to specify an orginal object, from the same Folder you are
    creating the Draft in. This will be your 'draft', on which you can
    make changes invisible to the outside world.

    The draft contains an invisible Session object that is immediatly
    started and joined, and an invisible UserFolder to facilitate
    extra users (for example, customers that want to be able to view
    your work on it as well, but have no access to it otherwise).

    The Principia Draft suffers two problems however. The first is
    really a Session object bug, in that security for Session objects
    is broken. The second problem is that the Userfolder and Session
    controls are inaccessible via the management screens.

    The latter problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately. Principia Drafts made use of
    the call to 'title_and_id' to insert links to its UserFolder and
    Session controls. As this now doesn't happen anymore, you will
    have to do this yourself.

    As long as you have access to Session objects, you can change
    users on a Principia Draft object by calling it's
    'users__draft__.manage_main' method, and reach the Session controls
    by calling its 'manage_approve__draft__' method. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main 

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

Hm, DTML methods can be called as well, naturally, that's why they're
called methods. They're called through URL. The DTML method then is
executed. This means executing any DTML in it and returning the
resulting HTML to the caller. One way of 'calling' a DTML method is by
using it in a form action, like this:

    <form action="your_dtml_method" method="POST"> 

(or method="GET", of course)

This does go through the browser, but it feels like you're calling
'your_dtml_method' when the user presses the submit button.

This is another way of 'calling' a DTML method:

<!--#var your_dtml_method-->

I'm sure there are more ways, and I'm a bit vague about this, so I'll
leave it up to other people to turn this into a nice FAQ. :)

Martijn

So that is what the MySQL Input wizard does. I've been meaning to look at
it. Instead of saving time by using it, I did it manually. It is not that
hard but you have to understand what is happening.

1. HTML form (eg. form_html) collects data and sends it to a DTML document
(eg input_html) (that is the only tricky concept).

For example:

<form action="input_html" method="get">
  <input name="num:int">
</form>

(That :int tag does error checking. It is optional. They are documented in
the Z SQL Database Methods User's Guide)

2. The receiving doc (input_html) calls an SQL method (eg input_sql) with
an in tag.

<!--#in input_sql-->
<!--/in-->

If you do a select after your INSERT or UPDATE you can use it between the
in tags, otherwise you can just display a message or do a redirect after it.

3. Your SQL method (input_sql) would be something like:

INSERT INTO database (num)
VALUES (
   <!--#sqlvar num type=int-->
)

<!--#var sql_delimiter-->

SELECT num, etc

You don't need to do a select but if you do don't forget the <!--#var
sql_delimiter--> between any SQL statements.

Have fun!

If you don't do anything with the returned data, a #call will suffice:

<!--#call input_sql-->

Hi.  I've been getting a lot of confusing complaints about gadfly
that turn out to be Zope bugs.  Just for the record.

ZGadflyDA doesn't support more than one db, gadfly does.
ZGadflyDA doesn't support newlines in string literals, gadfly does.
ZGadflyDA doesn't include kjbucketsmodule which makes gadfly run 10x
faster.
ZGadflyDA packages gadfly beta 0.2, whereas the current release is 1.0
  (October 1998) where a lot of other bugs are fixed....

I'm sure these will be fixed soon, in fact I'd offer a patch if I could
figure out how the thing works, but until then,

Umm - i know it's redundant at this point, but for completeness sake -
the Zope Documentation Project mailing list is open and ready for
business.  Thanks again to martijn for instigating this effort - have at

As a new zope user, and also according to my general documentation
sensibilities, 
i suspect it would be very valuable to have a catalogue of the various
special variables (like sequence-key and sequence-item) and the various
entities (REQUEST.cookies, ...) available to the DTML programmer.  There
may already be some sort of catalogues around - in which case pointers
to those kinds of resources would be very nice to have...

I think at least this part of your problem may be due to the fact that Zope
is running as a different user under IIS than it is under ZopeHTTPServer.
My guess is that it can't see your datasources since they weren't created
as 'System' datasources. Check under the windows ODBC control panel and
make sure your DSNs appear under 'system dsn', not 'user dsn'.

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the
MySQL
module to make sure it works. When I do, I get yet another error.

Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: libmysqlclient.so.6: cannot open shared object file: No
such
file or directory

The file does exist, so I am once again stumped.

Thank you for your continued assitance.

post script:

The current usage of gadfly in Zope makes gadfly do lots of parsing as in

insert into table(a,b,c) values (1,2,3)
insert into table(a,b,c) values (6,2,3)
insert into table(a,b,c) values (1,7,3)
insert into table(a,b,c) values (1,2,8)

The "right" way to do this would be to take advantage of gadfly's
dynamic parameter/multiinsert feature executing

insert into table(a,b,c) values (?,?,?)

ONCE with dynamic parameters list

[(1,2,3), (6,2,3), (1,7,3), (1,2,8)]

which would run much faster than thrashing the parser
with the individual inserts above (with kjbuckets present).
In general dynamic parameters on repeated statements reduce
parsing and binding overhead (even for other types of statements).

However, I understand this may be hard to implement as
it would require special features for the gadfly "adapter"
not of value for the other adapters. Oh well.

Anyway, in future please post/forward/crosspost any gadfly
related issues to the gadfly list.  I just discovered a pile of
complaints on the zope list this morning and I found it
distressing.  I don't normally read the zope list.

How can I evaluate a #var equivallent for setting a tag attribute value?

For example, Zope doesn't like this:

    <!--#sendmail smtphost=<!--#var smtpHost--> -->

or this:

    <!--#sendmail smtphost=smtpHost-->

(it tries to use smtpHost as the host name, instead of its value)

Try:

or this:

Subject: [Zope] Using Zope with CORBA (new user question)
Message-ID: <199903042212.RAA16927@hog>

I have a long running process that will be started by Zope.  This
process has a CORBA interface that is implemented using ILU.  I would
like to be able to asynchronously have this process generate data for
Zope.

My basic questions are:
	o Can I have an ILU mainloop inside of Zope?  (I really don't
	  care if I have to hack Zope or if I can use an external
	  method.)

	o Should I fork/exec the long running process and give the
	  process a URL that indicates where the data should be
	  written?  (I can use pickles or sql.)

	o How do I tell Zope that new data is avaliable if the process 
	  is external to Zope?

Message-ID: <Pine.LNX.3.96.990304141142.8459C-100000@taos.kavi.com>

Ok, what's the trick to getting special characters to be converted to
their escape codes (eg. " to &quot;). This is particularly important for
forms in which the user may enter these types of character. 

For instance, if I create a property on a folder that is a string, and if
the string I enter has quotes around it... it doesn't show in the
interface the next time I go to edit the properties. For example, in
MCExam, the 2nd sample question has this as an answer "bar, spam". If I go
to the folder's properties to change it, it doesn't show up. In the source
it looks like: 

<input type="text" name="ans3:string" size="35"
   value=""bar, spam"">

Obviously, if I then save changes, the value is gone altogether.

Is there a way of automatically converting quotes and other special
characters to their escape codes (like the sqlquote method)?

Thanks,

I do not know much about CORBA but you might find it helpful to check the
ZClient library that comes with Zope. You can use ZClient to script Zope
actions. In other words you can have your CORBA proccess running
independently of Zope and whenever there are available data you can call
Zope using ZClient and update whatever you need to.

Grovelling through the source I find something called html_quote in 
lib/python/DocumentTemplate/DT_Util.py, so I tried:

<!--#var nastyvar html_quote-->

Which seems to so the right thing in the generated source. I'm not sure
how to get at the equivalent method call, though.

Does that help?

(p.s. there's url_quote, as well)

I think we're trying to assign a string where a mailhost object is needed.
I'm not sure how to get around this, without an external method. Though
with an external method, it'd be pretty simple:

(warning: untested)

def get_mailhost(self,property_name):
	""" gets the mailhost """

	mailhost_id = getattr(self,property_name)
	return getattr(self,mailhost_id)
	
Or something like this... [shrug]

Both answers are much appreciated. Things start to clear up, but ...
As far as I understand zope it should also be possible to have forms send
data directly to external methods. How do I go abouth to make the argument
list in a python function so that it receives more than one 'form variable'.
1 is simple, but my form consists of 5. I get an error constructing the
python function to take 5 arguments. How is the 5 'variables' sent to the 
method? How do I get hold of the values each store?

Lotsa questions - probly me doing things the wrong way but - I'm learning:)

Yes. This is just what I was looking for.

This leads to a followup question/request for the group.

'manage_addProperty' calls various converters from ZPublisher.Converters
to format the properties values. Shouldn't html_quote be used when
formatting strings and text? This would be trivial to change. Would this
cause some problem I don't realize? If not, I'd like to add this to the
Collector for the next version.

Subject: [Zope] Simple DTML Method/Acquisition problem
Message-ID: <Pine.WNT.4.04.9903041647000.268-100000@rigoletto.ski.org>

I have a standard_html_header/footer pair which works much like that on
zope.org.

The header inserts a <!--#var sidebar--> in the left column.  The
sidebar DTML method is:

<!--#in expr="objectValues(['Folder'])"-->
<!--#if hidden -->
<!--#else -->
<a href="<!--#var id-->"><!--#var title--></a><p>
<!--#/if -->
<!--#/in -->

(show links to sub-folders which don't have the 'hidden' property set).

The above works fine in the toplevel folder.  In the subfolder, however,
nothing shows up, even though there are two folders which do qualify.

I'd tried originally to have it be a DTML Document and change the expr to
_.objectValues(['Folder']), but that doesn't work at all.

What am I missing?

Check if your DTML properly closes all tags. I had something similar
happening to me in a complicated DTML, when some condition failed to add a
</TABLE> tag. 

BTW you can use
<!--# unless hidden-->
...
<!--# /unless-->

Yes! This was exactly what was causing the error. I added a new 'System
DSN' which then showed up under IIS, and now I've got a shiny new and
perfectly functional Z ODBC Database Connection. 

Much thanks!

- Jay

PS - Don't know if this info is helpful, but I noticed that (after I set up
a valid System DSN) when my attempt to add a new Z ODBC DB Connection in my
IIS/1.10.2 environ was flawed for whatever reason I would receive the
cryptic 'HTTP Error 400 - Bad Request' from IIS. After some very quick
poking around I noticed that even after selecting a valid dsn, flaws such
as trying to add a connection with an ID already in use, or entering an
invalid connection string would give this 400 error - whereas in my
ZopeHTTPServer/1.9 environ I would receive relevant and helpful error
messages in such situations... Wish I knew more about how to help fix...

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the
MySQL
module to make sure it works. When I do, I get yet another error.

Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: libmysqlclient.so.6: cannot open shared object file: No
such
file or directory

The file does exist, so I am once again stumped.

Thank you for your continued assitance.

Where exactly is the file?

find out by doing a locate 'libmysqlclient'.

Let's assume that it is in /usr/local/mysql/lib.

The easiest way to accomplish what you want is this.

1.    cd /etc
2.    vi ld.so.conf
3.    Goto the end of the file and add a line that says
'/usr/local/mysql/lib'
      replace this with the exact location of you libmysqlient.so.6
4.    save the file
5.    run 'ldconfig'
6.    run 'sync' twice, this just makes sure all changes are written to the
disk.

This adds the mysql lib directory to the lib search path.

Why not use a MailHost Object? On that object you can then set the
appropriate SMTP Host, even from DTML code..

Yes, because you sometimes (most of the time, really), want to have the raw
input from the user. If you then use this raw input in HTML again, only
*then* should you quote out any HTML. Besides, what if I want the data to
be URL quoted? Or SQL quoted?

Just a quick shot: Could it be that the value 'hidden' is aquired from
somewhere else?

I did notice today that IIS 4.0 seems to be the cullprit. Whenever Zope
returns a 400 error (like 'sorry, an error occured') IIS mangles that into
the 400 Bad Request error.
This means the traceback is also gone. *grmbl*. Just try and add a
Principia Draft and not specify an ID, and compare this to the message
returned when using ZopeHTTPServer. I think I'll switch to ZServer.

Maybe this should go into the FAQ... I'll cc to ZDP

BTW, I hereby retract the bug I reported to the Zope Collector regarding
ZODBC connections being broken. I forgot to fill in the ID :|. IIS mangles
the returned errormessage.

What is the procedure for retracting bug reports? mail support@digicool.com?

Zopistas

I have encountered problems mainly associated with ZServer and ZAP:

I am using Zope-1.9.0 and the preconfigured Apache server to run my Zope
site. Last night (a couple of hours ago!) I installed ZServer. It wouldn't
run and I had to add the following to start.py to fix it:

import sys,os
sys.path.insert(0,os.path.join('..','lib','python'))

Later on upon entering the management screens I noticed that the id of the
top level folder dissappeared which caused the paths to my objects to
change. With ZAP (the preconfigured apache) I would visit:
http://www.gaaros.com:8080/Gaaros/ to get to the top level directory but
with ZServer is: http://www.gaaros.com:8080/ which spoils all kind of
links that people have on my site.

Switching back to ZAP I got the following error:

  <FONT SIZE="+2">Temporarily Unavailable</FONT>
  <P>
  The resource you requested is temporarily unavailable - please try again
later.
  </TD>
</TR>
</TABLE>
(102) failure during connect
<!--
No such file or directory
pcgi-wrapper-version 2.0a5
-->
</BODY></HTML>  

Seems like ZServer changed my root id from "Gaaros" to nothing.
I called PickleDictionary on Data.bbb directly from python but I could not
even see the subobjects. BTW can the Zope Data.bbb be accessed directly
from PickleDictionary??

Also trying to shut ZServer from the control-panel results in a core dump.

Ok enough for now, its very late and I cannot think anymore.

If anybody has any clues about the root object id problem please let me
know.

Thanks

Pavlos

No problem. Basically I filter all emails arriving in my personal account
that contain FAQ in the Subject: field. As I am subscribed to all the Zope
lists it doesn't really matter where you send it to.

This is a poor answer (as most here know I don't have the mental
horsepower to provide good responses :^), but...our _intention_ over
time is to have "ZServer" allow objects to be published via PCGI,
FastCGI, HTTP, FTP, and CORBA simultaneously.

Ideally we'd get some kind of Python implementation into the Medusa
handler layer.  Obviously this approach has some serious drawbacks...

Anyway, I realize that I'm not providing much of an answer, so sorry :^(

Right, understood.  We had to spend a lot of time figuring out Gadfly in
order to host it inside Zope.  Thus we labeled it "Demo".

I imagine that it is best for everybody if we take Gadfly out of the
base Zope and make it an external, no-warranty package like the MySQL
support.

This is really weird, it just reminded me of a (rather pathetic) dream I
had last night.  I dreamt that someone created a Python module that
would read Word files.

My DreamTV must be picking up the wrong channel.

I've been awfully interested in XML in the last few days.  Can you
describe what user-visible benefits PHP delivers due to its integrated
XML parser?

Additionally, we are working on Zope searching for a consulting project
right now.  Actually it is Zope Cataloging.  It's still a
consulting-only option, but plans are that eventually it will go "below
the line".

I *think* I have some good news to report on this, but before I squawk,
could you detail this gut-wrench a bit more?

There have been a lot of suggestions on this one.  Here's another one: a
command-line program that takes everything out, such as the wget
program.

I'd like to have this as well.  I've been doing a lot of thinking about
this lately.  It is a bit more complicated than expected, though...

This is the main reason I replied.

Having Zope as a free and Open Source(tm) platform is the heart of our
business plan.  A closed Zope would basically mean we start over
completely as a different company.  Thus, closing Zope is roughly
equivalent to closing our company.

With _that_ said, we still need to provide some assurances that we won't
legislate the connection between Zope and DC.  First, we are trying to
keep some arm's length distance between zope.org and Digital Creations.
We hope to formalize the way the community participates in the platform.
We expect to make it lucrative for other businesses to participate.

At the same time, we intend to pursue commercial opportunities atop the
platform for vertical applications.

Ultimately this is the same question put to Netscape regarding Mozilla
during the AOL talks.  The answer is simple: "The genie is out of the
bottle."

Since it is open sourced, Digital Creations must *earn* its stewardship
of Zope.  If we don't we'll become less relevant.

Earning the community's enthusiasm is pretty simple, I think.
Unfortunately we aren't doing a good job right now, though we are trying
damn hard.  But we'll keep trying...

In the meantime, I'm absolutely ecstatic to see folks in the community
step forward over the last month and lead the way.

Yep, the zope.org machine has five virtual hosts.

Previously answered.

Ditto.

We put them in the database.  The 3 Mb Zope binaries are served out of
the database, the PDF files are served out of the database.  This works
so well I don't even think about it any more.

hmmm. That's interesting because it works just like oracle or it
should,unless there are more bugs you haven't passed on to me.  Let me know
what caused the problems.  Basically any non-conformance with the db-api
is a bug.  Please report it to the gadfly-rdbms list.

Yes, this is fine.  BTW, it might be hard for your existing customers to
upgrade to Gadfly 1.0 since I think the db file formats are different
(that's why it was called beta, so I could change things like that).

I remain, Yours Truly,  Aaron Watters

I would suggest, first off, to use 1.10.2.  ZServer is being developed
against 1.10.2, and the latest Zap was tested and confirmed to work with
it.

Yes, there were discussions on this in the list about this problem.
Someone needs to go back, rassle up the discussion and submit it to the
ZDP.  Looks like you found the fix.

Hm.  Is your Zap .pcgi file named Garros or does your RewriteRule look
for Garros and then call PCGI?  If so that is why you need to use Garros
to reach the server.  ZServer can server right out of Zope and doesn't
have this problem.  Your description makes this sould like it is a
production site, I would not suggest running ZServer on a production
machine as it is alpha and still buggy.

This error comes from PCGI.  It can't find your .cgi file so Zope isn't
even being launched.  Did your zap.conf file change (specificly the
RewriteRule)?

You can open a Data.bbb file into a PickleDictionary, but you won't see
anything useful unless you really know what your doing.  The Database
itself is not a Pickle, it is a database of Pickles.  I have attached a
small 5K script that will be released with 1.10.3 which paruses the
database and generates reports.  In the future we are intending it to
translate the entire database into XML for transport. (Note, we do not
intend to use XML as the db format)

It's allways worth while! :)  I think the point paul was trying to push
is that we are interesting in publishing our objects over various
transport protocols.  If you want to look in this direction, probably
the best idea would be to write a Medusa handler.  Check out Sam's site
at:

http://www.nightmare.com/medusa

There currently exists an ftp and http medusa handler for Zope, which
you can look at in the latest ZServer alpha release availabe at
zope.org.  I'm not sure is there is a Medusa CORBA handler or not, I
suspect not, but maybe there's some type of CORBA out there written in
Python?

Yes.  ZServer really restores Zope's original intent from the Bobo days:
publishing objects through a variety of protocols.  I think ILU support was
once attempted back in those days.  However, a Bobo app at that time could
only have one publishing mechanism (ie, CGI, PCGI, FastCGI, ILU, etc...).
ZServer allows for multiple publishing mechanisms in the same application,
allowing access to the objects through the web, through FTP, or through any
other protocol developed for ZServer/Medusa.

Subject: [Zope] Documents for web and paper
Message-ID: <012c01be6729$74f6bd40$0201a8c0@hawkeye.bob.oc>

I'm looking for the best way to store and
retrieve documents with these requirements:

SPECS
*Easy storage and retrieval on the web
*Pretty printing on paper
*Easy simple collaboration (no checkout)
*One BASE format for both web and paper
*Base format *could be* edited with
   Word or WP
*Preserve text markup:
   bullets, bolds, underlines,
   tables, graphics, links...etc.
*Search by keyword
*Search by full text


*******
I look forward to comments and
Ideas on implementing this in ZOPE
Perhaps some of this has been solved
already and I don't know it.

EXAMPLE:
Say you have a small book/article
 that is fully contained in a WORD
or WP file.

It has chapters and sections:

Chap1 Plants
      Section1: Trees
      Section2: Flowers
      Section3: Vegetables
      Section4: Fruits
Chap2 Animals
      Section1: Dogs
      Section2: Cats
      Section3: Fish
      Section4: Humans

Ok, as a paper document in the
word processor it is laid out *nice* with
a new page for each chapter, section,
and subheadings for groups of paragraphs in
each section. It prints *nice* and can
even have a table of contents and index.

For the web, the whole book could be
one LONNNG web page.  Ugly and it
doesn't work well.

Ideally on the web each chapter and section
would be navigable with a left hand frame
like table a la http://www.zope.org.  Then
sections can be placed on separate pages
on the right.  This means that the one source
document becomes multiple html
"files" on the web site.

*Tree Navigation
Ok, for tree navigation like
http://localhost:9673/QuickStart
Each Chapter and Section becomes a folder and
the text from each section is contained in the same
named: "dtContent"  as in
...9673/QuickStart/Outline/Applications/External/dtContent

While the tree is nice,  and separate html "files" make the
website better,

*REVISIONS with TWO OUTPUTS

How do you do:
Make revisions to the source document in word/WP
and have it FLOW automatically to html format or
tree format for the web?

*Perhaps* XML could come to the rescue as holy grail
to help solve this problem???  I understand the idea
of mark up but how does it solve the problem of two outputs?

Can you have a template that automatically chops up
the SOURCE into the appropriate folders/files etc and
feeds it to ZOPE?   Can this or another template reformat
for pretty printing including page numbers that are
updated based on the planned printing?

Maybe I need to reconsider how documents are
stored as source, i.e. not Word.  And if not,  what
tool or mechanism would be best?  Maybe the
NATIVE source could flow to Word/WP or
via a template making for pretty printing.

Maybe for simple stuff, the source could be
simple text entered on a webpage or sent
by e-mail with *simple* markup and parsed
automatically?

*KEYWORD SEARCH
Ok, on the web (and Zope), the benefit is it's
searchability:  Do we "hide" keywords in the
source somehow and in addition use Chapter
and Section titles as Keywords?

Search for: "dogs"  gives a result of
Chapter 2 Section 1 in the example as
one entry.  Additional entries might
be lessor cross references such as
a keyword "dog" in the Section 4 humans
as "man's best friend".

*FULL TEXT SEARCH
Ok so we search for the word "Daisy"
and this word is found in the text in
sections: Flowers, Dogs (as a pet name)
and Humans (as a proper name).

The result is then three line entries that
take you to the words.

*Zope IDEAS for this?

I assume that it would be best to store
the documents and source in the ZOPE
database rather than an external datasource.

Thanks for any input on this

Nah -- getting rid of the hidden test doesn't change a thing.  Sorry I
confused the issue with that.

I think my problem has to do with my lack of understanding of the
interactions between acquitision, DTML Methods, DTML docs and namespaces.  
I just noticed that the standard html headers and footers are methods.  
That means, if I understand the earlier email, that the default namespace
in them is that of the thing they are contained in.  So, in my case, the
top-level Folder.

Now, in the sub-folder, the standard html headers and footers are acquired
from the toplevel folder.  The standard header does a #var sidebar, which
also lives in the toplevel folder, and that gets included fine.  Within
that sidebar, I'm not sure what the default namespace is -- my fuzzy
understanding makes me think that it should be either:

  a) the / Folder (the 'physical' container for the DTMLMethods)

  b) the sub Folder (the container for the thing which did the
     aqcuisition, namely the index_html DTML Document.

Problem is, neither of these makes sense given what I'm seeing.  If it was
a), I'd expect the 'objectValues()' call to return the same list of the
subfolders of the toplevel folder every time.  If it was b), I'd expect
the thing to work and give me the subfolders of the subfolder.

Let me try to summarize the hierarchy:
  
   /
     - index_html  (#var standard_html_header...#var standard_html_footer)
     - standard_html_header (#var sidebar)
     - standard_html_footer
     - sidebar
     SubFolder1/
     SubFolder2/
        - index_html  (#var standard_html_header...
                       #var standard_html_footer)
        - SubSubFolder1
        - SubSubFolder2       
    
The top sidebar shows SubFolder1 and SubFolder2, the /SubFolder2 sidebar
doesn't show a thing.

--david

PS: Thanks to pavlos for pointing out the #unless tag.

PS: For some reason the title of the root folder is "Zope" in the
    properties tag but doesn't show up in the tree or in the pathlinks.
    Anyone have a suggestion?

Try: <!--#var "sidebar(PARENTS[-1],REQUEST)"-->

This will call the method using the root folders' namespace, thereby
showing all qualifiying subfolders regardless of where the method is
called from. You might have to modify your method to construct absolute
URL's.

Thanks!  What I actually wanted was sidebar(PARENTS[0], REQUEST), but you
pointed me in the direction I needed.  Now I have to understand it, but
that's much easier with working code. 

This also led me to find a bug.  I was wondering why the REQUEST parameter
was needed, so I tried to remove it.  The next time I loaded a page
calling this code, the ZServer process died with the Win32 equivalent of a
segfault.  Is it just me?  I don't dare try it on another Zope server =).

Yeah, I already figured out that the problem was actually in the
OFS/properties.dtml file (I moved over to the zope-dev list, as I realized
this thread really belongs there). In properties.dtml the 'string' type is
listed twice:

  <!--#if "type in ('string', 'int', 'long', 'float', 'date')"-->
  <input type="text" name="<!--#var id-->:<!--#var type-->" size="35"
   value="<!--#var "_[id]"-->">
  <!--#elif "type=='string'"-->
  <input type="text" name="<!--#var id-->:string" size="35"
   value="<!--#var "_[id]" html_quote-->">

'string' needs to be removed from that first list. I'll be submitting this
to the Collector.

I'm new to Zope. I'm very excited about it's potential, but my first
impression is that I will need to master Python in order to use it. I
believe Python is an excellent language, but I do not have the time to
learn it. Several questions about this:

- Can I achieve anything useful in Zope without touching Python? I can
learn DTML, of course.

- if so, what I can and what I cannot do without Python?

- could I, for instance, do something like slashdot.org without Python?

- is there a plan to give Zope features (or ready-made
modules/factories) that would completely eliminate the need to work with
Python (for certain tasks that can be automated or turned into
templates)?

Subject: [Zope-dev] SQL methods q:

Hi guys:

I'm trying to write a SQL method though, and its giving me an error when I
try to test it..

Error, exceptions.TypeError: keyword parameter redefined
SQL used:
Could not render the query template!

The query I was using:

SELECT searches.engineID as engine,
 queries.param as query,
 MAX(searches.timestamp) AS time,
 searches.position AS position,
 MIN(lastsearch.timestamp) AS lastupdate,
 lastsearch.position AS lastsearch,
 searches.URL as URL,
 'NA' as change,
 engines.graphic as engine_gfx
FROM searches LEFT JOIN searches as lastsearch USING (queryID,engineID), engines, queries
WHERE lastsearch.timestamp BETWEEN <!--#sqlvar pstart type=int --> AND <!--#sqlvar pend type=int -->
AND searches.timestamp BETWEEN <!--#sqlvar pstart type=int --> AND <!--#sqlvar pend type=int -->
AND queries.clientID = <!--#sqlvar client type=int -->
AND queries.queryID = searches.queryID
AND engines.engineID = searches.engineID
AND searches.timestamp != lastsearch.timestamp
GROUP BY searches.engineID, searches.queryID
ORDER BY searches.engineID ASC, searches.queryID ASC, searches.timestamp ASC, lastsearch.timestamp DESC
;

Any ideas what I could be doing wrong?

BTW, Zope is great! I've been kinda messing around with it for a while,
also checking out PHP3 and other UNIX-based scripting languages and I've
very impressed.  As soon as I figure out what is causing this I plan to
write something 'cool' with Zope :)

TIA,

Hi Paul and Zopesters,

Paul writes in the thread:
[Zope] Some tough questions about zope...

I found a great description about XML in:
"20 Questions on XML"
http://builder.com/Authoring/Xml20/index.html

On Paul's Zope roadmap: (Jan 18th)
http://www.zope.org/Information/Roadmap

"(2) XML. Zope is a great fit for XML, even better 
with the machinery from Tabula going in. We also 
see XML becoming the basis for other initiatives, 
such as WebDAV and RDF. However, we just can't 
squeeze out the time to dive in deep. Rather, we'd 
love to see more community progress like that 
which popped up this weekend."

I did a search for postings that had "XML" 
in the subject and found
55 messages in ~6 threads between
Jan 8th and Feb 2nd

Other messages have "XML" in the body.

Hopefully we can get some OUTLINE of how ZOPE
and XML can work together.  --- A framework for
further discussions.

You can do just about anything with DTML.  In fact, most 'Products'
(read that, 'Zope Extnesions') are mostly DTML.  If your not writing a
Product then you can stay entirely in the domain of DTML.  DTML does use
a small bit of Python in itself, these are called expressions.  For
example, if you had an integer called num you could use:

<!--#var num-->

to 'render' it in your web page.  To get num + 1 you would use:

<!--#var "num + 1"-->

The contents of "" is a python expression.  But it's not a python
program.  If we didn't use Python we'd of had to have come up with some
other language like way of doing this that you'd have had to learn
anyway.

> - if so, what I can and what I cannot do without Python?
> 
Python is used for the following:

To write Products. This is hard core development.

To write External Methods, which are used to hook special or
wierd/pre-existing python functions into Zope.  This is rarely necesary.

> - could I, for instance, do something like slashdot.org

Yes.  There may be a 1% slice of something like slashdot needing a bit
of Python.  But remember, slashdot is a huge application written
entirely in Perl.

Yep.  These are called Zope Classes.  They are still in-house here at
Digital Creations because we are still debugging/figuring them out.  A
Zope Class lets your create your own objects that can be added into Zope
without writing Python code.

More information on my front.. I've been fiddling around a bit trying to
find out what is going wrong..

I'm using ZServer/Zope 1.10.2 with ZMySQLDA that I just downloaded 2 days
ago.

The traceback is as follows:

<!-- Traceback (innermost last):

    (Object: CopySource) TypeError: (see above)
-->

line 384 of DA.py -- __call__ reads:
query=apply(self.template, (p,), argdata)

I added a bit of debugging code and was able to a take a look at some of
the data being passed around:

argdata was {'sql_delimiter': '\000', 'client': '1', 'pend': '1',
'pstart': '1', 'sql_quote__': }

This is starting to confuse me because simple queries work fine within
Zope, its only the query that I posted in my previous message that seems
to be fowling things up.

I'll keep slagging away until either I figure it out or someone tells me
its not something I've done and that I should submit it to the Collector
:)

Subject: [Zope] DatabaseError: Corrupted data record...
Message-ID: <199903052137.VAA24776@finan.ncl.ac.uk>

Hi all,
Firstly, I'd like to thank everyone for the detailed replies I got to my 'Tough Questions' post.
I'll reply individually to you all and try to answer some of the questions that *I* got asked, but as 'they' say...

"...there is one small problem!" (MPaTHG)

My database has got nuked.

I don't know how it happened, but this is the tail of my serve.errors file

  File "lib/python/OFS/Application.py", line 319, in open_bobobase
    Bobobase=Globals.Bobobase=Globals.PickleDictionary(
  File "lib/python/BoboPOS/PickleDictionary.py", line 159, in __init__
    db=apply(DBType,(),storage_options)
  File "lib/python/BoboPOS/SimpleDB.py", line 221, in __init__
    self.open(file_name,create,revision_time,meta_index,read_only)
  File "lib/python/BoboPOS/SimpleDB.py", line 287, in open
    try: self.index,self.pos=read_index(
  File "lib/python/BoboPOS/SimpleDB.py", line 1365, in read_index
    raise DatabaseError, ('Corrupted data record at %s' % pos)
DatabaseError: Corrupted data record at 1087646

Trying to 'start' the server again just results in the serve.errors file being touched.

As you'll know from my 'Touch Questions' post, I'm a novice in Zope (but I've bought the Lutz 'Programming Python' book, have two more on order and have been reading and rereading the docs all week...so I'm learning fast), but this has me stumped.

I haven't got too far into my Zope 'career' yet, so I won't be devastated if I have to replace the database from scratch (how do you do that by the way?), but I'm sorta worried about the way that all my work seems inaccessible to me now.

any and all help would be ... appreciated.
tone.

Okay, now it makes sense.

Is 'client' a reserved variable?

If so, perhaps a warning would be nice if you attempt to use a reserved
variable as an argument to a SQL method.

Argh.. so I got that fixed and now I am getting another traceback when
testing the SQL method!

I can't believe it :)

Here it is:

Error, exceptions.KeyError: unhandled

I need to detect not only whether a list is empty (that's easy with the
#if tag for example), but also whether all of the elements in the list
have a property. In Python, one could do this with something like:

  empty = 1
  for element in theList:
    if not element.hidden: empty = 0
    print element
  if theList and not empty:
    print "no non-hidden elements"

What's the equivalent DTML?  Can one create a variable in DTML?

Can anyone tell I miss my Python when writing DTML? =)

Oh my :-)

I didn't try such a thing before. But because the Zope
database is always only appended to (if I'm understanding right),
you might try to truncate the file upto that offset and see
if it is working again? (please keep a backup :-)

Subject: [Zope] Authentication and Zope.cgi
Message-ID: <199903052211.PAA16445@daikon.tuc.noao.edu>

I'm in need of a bit of clarification about how Zope starts up and when
it decides to do its authentication and why.

I'm running 1.10.2, solaris 2.6, apache, pcgi, netscape 4.07.  When I request
mymachine/Zope/manage   I do indeed get the normal management screen.
I haven't been asked in some time for a password, which suprises me;
the 'access' file exists and (but?) hasn't changed since installation.

I'd really like the root folder to say something other than Zope, so
I added to Apache a second rewrite rule that substitues 'mpg' for Zope
in the two places (restarted Apache), and copied Zope.cgi in cgi-bin
to mpg.cgi .  These two cgi files are identical so they point to the
same /var directory.

If I try   mymachine/mpg/manage  ,  I get an authorization failed box,
and upon clicking 'retry', I get the usual authentication box with
the correct 'access' user entered.  I type in the correct password and
the system fails again ("You are not authorized to use this system.
Username and password are not correct").

So, I'm very curious as to what's going on ... and I wouldn't mind
learning how to change the top of the root name as well.

I try hard to do everything in DTML but ... python is such a breeze.
OTH if you have most of your code written in DTML it is so easy
to create similar products and move them around.

What version of Zope are you using? What OS?  Were you using NFS? MySQL?

Please send *in private mail* me a gzipped tar file (or Zip file) 
containing the Data.* files from your var directory.

Any other thoughts you might have regarding events leading up to this
would be helpful.

Good point.  I should have mentioned that as a quick
recovery, especially if the location is near the end of
the file.

But please send me the file before you truncate it. :)

Hmm. I want to create a variable whose value is given by another value.
Doing:

<!--#with "_.namespace(foo=<!--#var id-->)"-->
<!--#var foo-->
<!--#/with-->

doesn't make it through the parser.  

I've tried adding various quotes to no effect.

I think I'm going to work on understanding ExternalMethods -- this syntax
is not made for me. =)

Why does my ZMySQLDA Z SQL Method die with a KeyError: unhandled message?

Well, I was looking at the code for the MySQLmodule and it appears that it
has problems handling some fields.

This appears to be a limitation of the MySQLmodule.  It currently does not
handle the LONGLONG datatype longer timestamps use.

At least I assume its the LONGLONG that is messing it up.  I haven't
looked into that much detail to be honest.  

I'm not quite sure if this is something that should be included in the
FAQ, or considered a known bug, or submitted to the Collector?

Thanks,

This surprises me, since as far as I can see, one is always asked for password
accessing /Zope/manage. Does netscape 4.07 automatically go through authenticate
procedure?

There are at least two possibility.
1) Misconfigured rewrite rule.
2) mpg.cgi is not altered suitably.
(oh, 1+2 gives the 3rd possibility).

I was in a similar situation a few days ago. Now one of apache virtual host on my
linux box has 1) ordinary apache site tree, 2) experimental(read 'for play') Zope
site under  hostname/Zope/ (through Zope.cgi)
3) public Zope site under hostname/public/ (through public.cgi)
If this is similar enough to what you want achieve and you are desperate enough,
just mail me your rewrite rule and Zope.cgi & mpg.cgi with sensitive parts
altered suitably. But be aware that I am new to rewrite rules and pcgi
world(hence if you are desperate enough).

This is easy. Just edit BOBO_REALM (NAME?) in your *.cgi file.

ps.  my Zope's have their own var/Data.bbb but you want your Zope to point to the
same var/Data.bbb. Oh this seems far beyond the capacity of mortal being. If you
really want need this setting, I guess, the easist way to achieve it is getting
Zopal blessings from DC(i.e. make a consulting contract with DC).

Message-ID: <x1jhfrzcy2z.fsf@unhinged.engr.sgi.com>

Hello all, I recently discovered Zope and am diving right in.

I have a Z SQL Method with the following Query Template:
---
select *
from rw_ProjectData 
where _id = <!--#sqlvar projID type=int-->
---

when I test it, I get the following:
---
Sorry, an error occurred.

I'm guessing that the parsing of the tokens picks up on underscore
('_') even outside of the DTML tags. Does anyone have a solution or
workaround?

Ouch!, what we do is save the word docs as RTF. A free program (written in
Omnimark) called RTF2XML then trundles through it and creates well-formed
and valid XML. I then pass it through another Omnimark program that I wrote
that turns it into XML that is more suited to what we want.


>I've been awfully interested in XML in the last few days.  Can you

>XML parser?
>

Background:...
PHP is a (non OO) server-level scripting language, usually delivered as an
Apache module, that has it's roots in C, but with some of the arcane bits
removed. It's database integration is very good. The authors have recently
built the (almost XML-industry standard) parser Expat into it.
...

From my point of view, having the XML parser in PHP meant that (a) I didn't
need to call Perl CGIs (with all that overhead), (b) I'd understand the code
a bit (I *cannot* do Perl!), (c) there might be a performance boost from
having the parser in the Apache Module and (d) I'd be able to map XML
elements such as <topic> ... </topic> into HTML <div> ... </div> tags or RTF
control codes (all of which would be read from a user-defined database) -
thus leading to the 'Holy Grail' (ouch!) of being able to render the
documents into whatever form the end-user wanted. As well as that, using XML
means that I can select all <topic> .. </topic> tags that match a certain
criteria (eg, all first-year study guides that mention cell biology) from
*all* our study guides and create a 'composite' document that would be
passed through the XML 'converter' to get custom HTML and RTF docs.

Of course, once I 'got into' XML I found out that just having the Expat
parser around didn't necessarily mean I was going to get all that for
free...ie how 'do' you 'search' an XML document to get those matched <topic>
tags (and possibly their children). Enter XQL and it's friends, DOM and XSL.

XQL (Perl module based on a W3C recommendation) works, but it's slow. 

In short, I was at an impasse. The level of work needed to incorporate XQL
into PHP (as a CGI) or (gulp) rewriting it as PHP was just too much.

I installed the XML-Config product for Zope and my appetite was whetted. I
read about the XML-sig and downloaded the XML-0.5 toolkit from python.org. I
tried one or two examples out ... and my jaw literally fell open. By the
time I'd looked in the 'dom' directory I was almost gibbering. This was
something I felt I might be able to understand (and definitely use).

Ooops...I'll shut up as I'm waay of topic.

No, but I've spent the last week muttering 'ok, I can use UserDB to
authenticate against our StaffDB and allow per-user access to the file
upload area', 'yeah, should be able to rewrite my PHP Multi-Choice Question
engine in this DTML gubbins', 'ok, I'll pull in the Perl script that does
xxx by using a redirect' and the like ... which is probably more scary!

Simply this: 
Zope seems to do just about everything I need (which is basically to provide
a *framework* for the Electronic Curriculum - others will fill in *and
manage* the content). I can then concentrate on providing features that
people need and 'rolling them out' to the users of the systems, confident
that they will integrate into the whole system. 

I think it's a paradigm-shifty thing more than anything else. Everyone in
our group *knows* that an .htaccess file allows access to the files in that
directory. They all have at least a basic grasp of CGI programming and all
recognize the mapping between files in a unix file structure and their
representations as web pages. People using Zope will have to break that
habit of logging in to change a file ('cos it ain't there!).

(for the time being, I've desubscribed from the PHP-lists to give me more
room to think!...)

Message-ID: <3.0.6.32.19990306180733.009318b0@hito.eccosys.com>

I think there must be an easy way around a little trouble I'm having, but
it's had me stumped for a few days and I can't find any mention in the
list/docs.

From a dhtml method I want to access a subfolder's sql methods, which is
easy enough using <!--#with SUBFOLDER--> <!--#/with-->. The problem is,
because of the amount of methods involved and in order to keep things
flexible I want to add the <!--#with--> to a standard_header, and the
<!--#/with--> to a standard_footer. Of course, Zope nixes this. So I was
hoping there was an end-run around this dilemna - some other way to give
access to subfolders. 

I've tried including the opening and closing WITH's in the same document
surrounded by IF's with no luck, and have been wondering if there's a way
to set a folder property to accomplish this...

You cannot nest DTML but you can use _[] to access the namespace. For
instance you could do:
<!--#with "_.namespace(foo=_['id'])"-->

I too miss Python when working in DTML.  But in this case, I think that the
following will help:

Hi!

I'm reading 'A technical introduction to object publishing with Zope'.

The doc says 'Creating a Zope application is simply a matter of creating a
regular Python module containing the objects to be published, and placing
this module along with some Zope-provided support files in the appropriate
place on a web server'

The doc continues to say that the zope documentation covers this prosess,
but I'm not able to find it. So my question is - what are those
zope-provided support files, and where am I supposed to place those file
along with the python module that I've created?

Message-ID: <199903072025.UAA09186@cheviot.ncl.ac.uk>

Hi,
I've read on the zope-dev list that Zope is not multi-threaded.

Does this have any ominous implications for server performance? I believe it
means problems for people writing products, but does it give problems for
folk using Zope in an 'install products and use them' scenario?

many thanks for any thoughts,
tone.

We can discuss this now, but in a short while it won't really matter.
Zope as we know it now is not 'multi-threaded'.  The real issue
concerning Zope is one of concurrency, since the 'threading' of requests
is ussualy created by the web server (Apache using multi-processes or
Medusa (ZServer's) use of select(), neither of which use actual
'threads').  There are two areas that we are working on to make zope
concurrent.

The Database:
	There is a new version of BoboPOS, called BoboPOS3.  It is
currently alpha.  BoboPOS3 supports concurrent processes opening,
reading and writing the Object Database.

'Concurrifying' Zope:
	Concurrent programs have to be careful about some issues.  In
particular, the use of global data.  These can sneak in on you in wierd
ways.  For example, in the regex python module (yes, regex has been
depreciated for re, but for now regex is faster) certain uses of
compiled reg expressions don't work when two 'threads' enter the same
expression.  Also, there is an issue about passing mutable objects as
default arguments to methods.  To be truely thread safe, default
arguements need to be immutable, or mutable arguments can only be used
in immutable ways.

These are, as you said, developer issues.  Product developers have to be
careful not to block Zope for long periods of time.  People in the
'install and use them' scenario should not use these types of Products
unless they are sure the block times are low, and product developers
should be very, very careful about moving their software out into the
world if the product blocks.  It should be made clear to the user that
this software could stop up the whole works.

Why is won't matter soon is because we are working on making Zope fully
concurrent.

Subject: [Zope] Q for the group
Message-ID: <l03130300b309086b41cf@[206.40.158.77]>

Advice needed, opinions wanted.

I have a situation where there is a group of users with both a private
space and a public space. The users homepage is considered private with the
public space where all anonymous viewable docs are held. I have two
thoughts on how to do this, Zope is capable of either method, I'm curious
which method everyone else thinks best, and why.

First method;
community folder (contents public viewable by permission)
     user_folder (contents not public viewable by permission)
	users manage page (not public viewable by aquisition)
	users public folder (public viewable by permission)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by aquisition)

Second method;
community folder (contents public viewable by permission)
     user_folder (contents public viewable by aquisition)
	users manage page (not public viewable by permission)
	users public folder (public viewable by aquisition)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by permission)

Both have advantages and disadvantages, either way I end up with on - off,
off - on, in the permissions hirearchy. Anyone have a good argument for
either method?

Subject: [Zope] Why doesn't this loop over files?
Message-ID: <v04104422b3094ee5414d@[128.240.198.13]>

Hi,
I've d/led the ZopeDemos folder, installed it and started learning 
more about Zope, but there's something happening that I'm not sure 
about.

The 'looping' example doesn't seem to iterate correctly over new 
additions to the folder. The DTML is here:

<!--#in "['Document','Folder']"-->
<!--#if "objectValues(_['sequence-item'])"-->
   <H3>Objects of type <!--#var sequence-item--></H3>
   <TABLE BORDER=1>
   <TH>Id</TH><TH>Title</TH>
   <!--#with subFolder-->
      <!--#in "objectValues(_['sequence-item'])"-->
        <TR><TD><!--#var id--></TD>
        <TD><!--#var title--></TD></TR>
      <!--#/in-->
   <!--#/with-->
   </TABLE>
<!--#/if-->
<!--#/in-->

If I create a new DTML method or document in the folder 'subFolder', 
it isn't recognised. I've even copy/pasted the documents that do work 
into the subFolder with no joy. Curiously, new folders *are* 
recognised.

My Question is: What's preventing Zope from reading *all* the 
Documents in the subFolder?

This would be the core of my first real application in Zope (a 
resource upload/download facility for staff here) so any advice would 
be appreciated.

thanks
tone.

Yes.

Definitely. We have dozens and dozens (eventually hundreds) of files 
(QT movies, PowerPoints, Word Docs and the like - the mean size is 
about 600k-1Meg, but we have quite a few monsters at 6-7 Megs).

This would be excellent news for us.

Does this ensure that MIME types are kept with the document, so that 
'clicking' on its link will ensure that the correct helper

Ad-hoc Zope FAQ version 0.1.1

Note on the use of the Zope mailing lists:

    The Zope Documentation Project has its own mailing list

    Please join and help us document Zope!

Note on the categorizing of this FAQ:

    This FAQ is a FAQ in progress. It is uncompletely unstructured;
    unrelated questions are mixed haphazardly. If you feel the calling
    to help categorize the FAQ into sections, or if you'd like to
    maintain a particular FAQ section, please mail to the ZDP
    list. Thank you in advance!

Note on the use of StructuredText:

    See the (currently) first FAQ entry for information on how to
    render this FAQ into HTML using Zope. For more information on
    StructuredText see::

        http://www.zope.org/Documentation/Reference/StructuredText

    but this link is currently not completely up to date; see the
    comments in 'lib\python\StructuredText\StructuredText.py' for the
    current documentation.

* How do I render the Structured Text FAQ into HTML cleanly? (in Zope)

    When including Structured Text (STX) from a DTML Method into
    another Document with the 'fmt="structured-text"' attribute, it
    will be quoted twice. This is because the '__str__' method of the
    'DocumentTemplate.HTML' class automatically quotes its HTML when
    called.

    You can work around this by calling the STX document's
    'read_raw()' method to get the unquoted version.

    This way we can use unquoted Structured Text examples in our FAQ::

        <!--#var "FAQ_Document_stx.read_raw()" fmt="structured-text"-->

    Note that if the STX comes from a property the 'read_raw()'
    workaround is not needed.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

    Another possibly is to use '_.getitem()', like this::
   
        _.getitem('sequence-item')

    The difference is that the first renders 'sequence-item' through
    DTML, whereas 'getitem()' does not; it returns the raw value of
    'sequence-item'.

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their
names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like 'REQUEST.form', 'REQUEST.cookies' and even
    'REQUEST' itself. Just call the 'items()' method of the
    dictionary, and the #in tag will provide a 'sequence-key' and
    'sequence-item' variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
          <!--#var sequence-key-->:<!--#var sequence-item--><BR>
        <!--#/in-->

    Use 'REQUEST.cookies.items()' for all your cookies, and
    'REQUEST.items()' for all 'REQUEST' variables, including CGI
    Environment variables.
    
    If you don't mind the format, you could use '<PRE><!--#var
    REQUEST--></PRE>' as a shortcut.

* What is a Principia Draft?

    A Principia Draft is a special copy of any Zope object that is
    invisible to visitors of your site. You can make changes to this
    copy, and grant access to outsiders to view your changes (or work
    along with you). When all changes are done, you can approve all
    the changes, or discard them. Approving will make the changes
    permanent and visible to your audience. However, currently Drafts
    can appear to be broken.

    To add a draft, choose Principia Draft from the popup menu and
    click 'Add'. Next, you will have to supply an ID for the Draft,
    and specify on what base object you are going to work. Clicking
    'Add' in this screen will create the Draft for you. Next, you will
    have to specify who will have access to the Draft.

    Here the problem starts, because of the way Drafts are
    managed. First, a Draft doesn't acquire any users from its parent,
    so you will have to add anyone who has to have access explicitly,
    even if they have already been access to a parent Folder. But the
    biggest problem is that you can't reach the UserFolder and
    Approval screens via the management screens. This will make a
    Draft a bit harder to use, but it still is workable.

    This second problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately.  Principia Drafts made use
    of the call to 'title_and_id' to insert links to its UserFolder
    and Approval management screens. As this now doesn't happen
    anymore, you will have to type in the URLs to the screens
    yourself.

    You can reach the screens calling the Draft object's
    'users__draft__.manage_main' and 'manage_approve__draft__'
    methods. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

    So, the next step is typing in the URL to the Draft's UserFolder
    management screen, and adding all users that should have access to
    the Draft. These users can now edit and view all changes made to
    this Draft.

    When done, you go to the 'manage_approve__draft__' management
    screen, and approve, or discard the changes.

* How does my Folder Product load default documents?

    Create a list of tuples containing filenames (without '.dtml') and
    title pairs::

        self.defaultDocs = [
            ('index', 'NotMail'),
            ('address', 'Address Book'),
            ('attach', 'Attach a File'),
            ('composer', 'Compose a Message'),
            ('contact', 'Contact Developers'),
            ('search', 'Search Your Mailboxes'),
            ('results', 'Your Search Results'),
            ('folder', 'Mailbox'),
            ('message', 'Message'),
            ('help', 'Help'),
            ('lookup', 'Lookup Users'),
            ('standard_footer', 'Standard HTML Footer'),
            ('standard_header', 'Standard HTML Header'),
            ('noto', 'Message must have at least one recipient.'),

        # Then iterate over them and create each one

        for id,title in self.defaultDocs:

                self.defaultDocFile(id, title, id)
            except:
                pass

        # defaultDocFile is a handy little function:

        def defaultDocFile(self, id, title, file):
            f=open('%s/Products/NotMail/%s.dtml'
                   % (SOFTWARE_HOME, file))
            file=f.read()
            f.close()
            self.manage_addDocument(id, title, file)

    When you are debugging your DTML, it's a pain to keep deleting and
    creating new instances of your object in order to load the new
    dtml files off of the disk. This function comes in handy::

        def refresh_docs(self, REQUEST):
            """ refresh documents from disk (for debug purposes) """
            
            for id,title in self.defaultDocs:
                try:
                    self._delObject(id)
                except:
                    pass
                try:
                    self.defaultDocFile(id, title, id)
                except:
                    pass
            return self.manage_main(self, REQUEST)

    Then, assuming your object has an attribute 'debug' you can define
    some DTML like so in your manage_main screen::

        <!--#if debug-->
        <p><a href="refresh_docs">Refresh Documents from disk</a></p>
        <!--#/if debug-->

* How do I add management tabs to my folder sub-class?
   
   If you subclass 'OFS.Folder.Folder' to build a folderish object,
   you may want to keep around the old Folder management tabs, but add
   some of your own as well. This can be done by mucking with the
   Folder class 'manage_options' attribute. One problem is that you
   might want your own custom 'manage_main' but the FolderClass uses
   'manage_main' for displaying the contents of the folder. Here is
   what I did for my EMarket product.
   
   By examining Folder's manage_options::
   
       for option in Folder.manage_options:        
           print option 

   We get the following output::

       {'label': 'Contents', 'target': 'manage_main', 'action':
'manage_main'}
       {'label': 'Properties', 'target': 'manage_main', 'action':
'manage_propertiesForm'}
       {'label': 'Import/Export', 'target': 'manage_main', 'action':
'manage_importExportForm'}
       {'label': 'Security', 'target': 'manage_main', 'action':
'manage_access'}
       {'label': 'Undo', 'target': 'manage_main', 'action':
'manage_UndoForm'}
       {'label': 'Find', 'target': 'manage_main', 'action':
'manage_findFrame'}
   
   Notice that the "Contents" tab calls Folder's manage_main attribute.
Just
   rename that in your sub-class with something like::
   
       manage_contents=OFS.Folder.Folder.manage_main
   
   and assign that to a different tab. Here is the beginning of the
MarketItem
   class from the EMarket product::
   
       class MarketItem(OFS.Folder.Folder):
           """A MarketItem """
   
           # Specify a name for the item type:
           meta_type='MarketItem'
   
           # Specify a relative URL for the icon used to display icons:
           icon='misc_/EMarket/marketItem'
           
           # rename Folder's manage_main to manage_contents
           manage_contents=OFS.Folder.Folder.manage_main
  
           manage_main=HTMLFile('marketItemEdit', globals())
           manage_image=HTMLFile('marketItemImage', globals())
   
           # Specify definitions for tabs:
           manage_options=[
               {'label':'Attributes', 'action':'manage_main'},
               {'label':'ImageUpload','action':'manage_image'},
               {'label':'View',       'action':''},
               ]
   
           # add in the options from the Folder class.... change
           # the 'action' for Contents to 'manage_contents' 
           for item in OFS.Folder.Folder.manage_options:
               if item['label'] == 'Contents':
                   # be sure to use a *copy*
                   manage_options.append(item.copy())
                   manage_options[-1]['action'] = 'manage_contents'
               else:
                   manage_options.append(item)

Message-ID: <14051.53317.19816.135841@cuckoo.EMBL-Heidelberg.DE>

Hi Zopists,


using StructuredText 
 ($Id: StructuredText.py,v 1.11 1999/02/08 18:13:12 klm Exp $)
for content generation, I find that I can't include tilde (~) characters in
hyperlinks, i.e. a  string like 

	"brabbel":http://www.embl-heidelberg.de/~ehrlich.

is not mapped to 
	
	<p><a href="http://www.embl-heidelberg.de/~ehrlich">brabbel</a>.</p>

but output as literal 

	<p>"brabbel":http://www.embl-heidelberg.de/~ehrlich</p>.
				
I tried to fix StructuredText,StructuredText.__init__ by inserting '~' into
the gsub statements. No success whatsoever...

As I couldn't find this entry neither in the Collector nor in the archive,
I wonder whether somebody has a patch sitting somewhere?

Cheers,
	Lutz

I just ran into this error. When I did a SELECT * on joined tables it would
give the error but if I named the fields I needed it worked. I played with
it a little and got the error again when I named a field that ended in _num
in the SELECT. I have four such INT fields that I don't need, they are used
by the JOIN, and have _n counterparts in the JOINed tables (see SQL below).
As you can see my SELECT list is long and it would have been nice to just
use a * since I need almost all the fields.

Everything works fine in MySQL client but from Zope I can produce that error.

Maybe there is some conflict with the *_num names. What are your field names?

I was able to find a work around.  The problem was the handling of
the TIMESTAMP datatype by the MySQLmodule.  It doesn't know how to handle
a long timestamp unfortunately, so you'll want to retrieve it as a UNIX
timestamp or as a formatted date using one of MySQL's many date functions.

The other thing is that I doubt it handles double long integers since
AFAIK Python doesn't handle these without an extension module.

If your query is returning any of these you'll most likely get this
response from Zope...

   It sure does:

Python 1.5.2b1 (#2, Jan 18 1999, 11:01:20)  [GCC 2.7.2.1] on freebsd3

    Spiffy, eh?  I'm pretty sure it's arbritrary-precision, which means you can
make numbers as large as you have memory for.  Or is this not what you
mean?

Hey, I'm glad you proved me wrong :)

It looks like there is a limitation in the MySQLmodule when handling
MySQL's LONGLONG datatypes that could probably be corrected.

I may take a look at this later, but I am thinking I may just store UNIX
timestamps in my database since this is more portable across databases
anyways.

But anyway, this may be a FAQ item as I'm sure other people may run into
it.

Hi All,

I fetched FAQ tool from "http://www.zope.org/WebReview/" but the

* __init__.py

*version.txt

*Product.dat


No, FAQ.py file. Strange no. Thus, this is maybe why I cant view

Here is a strange one -- I am getting an L on the end of integer numbers
from MySQL. (They are INT not BIGINT!) It didn't happen in 1.9, and it
doesn't happen with methods that I created in 1.9 and moved to 1.10.2 (I
think).

In <!--#var--> I have to use fmt='%d' to get rid of it.

I also had a problem when I tried to use one in a redirect:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(num))"-->
produces:
http://server/dir/file_html?num=53L
which causes an error.

I got around that by adding an int function:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(_.int(num)))"-->


Has anybody else experienced this problem? Having to add all this extra
code is driving me crazy!

While this may seem strange, this is in fact the normal contents of a
Product distribution file for a "levered product". When you build a product
through the web inside the control panel, these are the normal files Zope
creates inside the product distribution.

>Thus, this is maybe why I cant view 
>Faq in the list of objet in Zope!!

Unfortunately this is not the case. The reason you can't use the FAQ is
that there is a bug in Zope which keeps some people from being able to use
levered distributions. As discussed on the list, it appears to be related
to zlib compression.

We are aware of the problem and are working to solve it.

Thanks for your patience.

-Amos

P.S. If you're curious about a bug, you can try searching the Collector.

http://www.zope.org/Collector

In this case a search under "lever" or "faq" would turn up the existing bug
report for this problem.

No real issues, just d/l the source release and try compiling Zope.  I'd
recommend having Python 1.5.1.  To build the source release to use the
built in simple web server, try:

'/usr/local/bin/python1.5.1 wo_pcgi.py'

to use with Apache (Note, d/l Zap and look at it's .conf file)

'/usr/local/bin/python1.5.1 w_pcgi.py'

Change the command line to reflect your python binary.

Check out, I think, INSTALL.txt in the doc directory.  All the C is
ANSI, and python is python (grin) so you shouldn't have a problem.

Message-ID: <3.0.5.32.19990308164035.011451b0@mail.aracnet.com>

Hi Guys:

I think I've nailed the problem that was keeping people from using the FAQ
Tool and levered products in general under windows.

I'd love some confirmation that this does or does not solve people's problems.

The fix is to open the product.dat file in 'rb' mode. To do this, change
line 420 of lib/python/App/Product.py to:

        f=CompressedInputFile(open(home+'/product.dat','rb'),name+' shshsh')

Again, let me know if this doesn't work for you.

-Amos

P.S. Here's a little FAQ to tide you over until you're happily building
your own ;-)

Q. What's the FAQ Tool any way?
A.  Find out for yourself at: http://www.zope.org/WebReview/

Q. What's a levered product?
A. A Product created through the web by building it inside the Control
Panel. See the Zope Manager's Guide for more information.

Yep.  Didn't work for me before (even for Levered Products I made myself)
but now it does.

This fix works for me (lline 407 in my Product.py) 

HOWEVER ... you must delete the FAQ product from the control panel, 
then restart ZServer for this fix to take effect. Apparently the old FAQ in 
bobo inhibits re-reading of the product.dat file.

There's a bug in the code, something I noticed when I was playing 
with the examples too. this is the fixed version:

001 <!--#in "['Document','Folder']"-->
002 <!--#with subFolder-->
003 <!--#if "objectValues(_['sequence-item'])"-->
004    <H3>Objects of type <!--#var sequence-item--></H3>
005   <TABLE BORDER=1>
006   <TH>Id</TH><TH>Title</TH>
007      <!--#in "objectValues(_['sequence-item'])"-->
008        <TR><TD><!--#var id--></TD>
009        <TD><!--#var title--></TD></TR>
010      <!--#/in-->
011   </TABLE>
012 <!--#/if-->
013 <!--#/with-->
014 <!--#/in-->

About the bug and the fix:
the bug was due to the statement <!--#if
"objectValues(_['sequence-item'])"-->
looping over the current folder, not the subFolder which it should be.
By moving the "with" statement to enclose it (see line 002), the
statement <!--#if "objectValues(... now loops over the objects inside
the folder named "subFolder".

I don't know who is maintaining the ZopeDemos product (or if it's
being maintained at all), 
but I hope he/she takes note of this and posts an update. 

Hope this helps.

PS. I'm playing around with the Confera product (making it more
slashdot-like) but I know it's
not "officially supported" by Zope/DC -- so who's maintaining it? I
have some detailed questions about the code (but I don't know if it's
off-topic for Zope/Zope-dev).

Zopistas

The new version of the FAQ has been uploaded at:
http://www.gaaros.com:9673/FAQ

The format has been changed after Martijn Pieters suggestions. It now
supports structured-text as the default format. Actually it was pretty
easy to upload Martijn Faassen's FAQ.

The e-mail uploading option has been dropped. If you want to submit a
FAQ entry you can do it over the web. Also the XML DTD has been changed
slightly. A typical entry would be:

<entry>
<section>DTML Scripting</section>
<question>How to you become a hermit?</question>
<author>Pavlos</author>
<email>pavlos@gaaros.com</email>
<answer>
Simple:
	
  - Install Python

  - Install Zope
</answer>
</entry>

Only the section and question fields are required. Everything else is
optional. You can view the DTD on the site. Suggestions will be
appreciated.

A few days late for this thread, but I just ran into the problem.

After reading through the thread, and poking around the MySQLmodule source
a bit.  I thought I'd see what happened if I changed the unhandled to long
in the MySQLmodule...
At line 440 in MySQLmodule.c, change 'unhandled to 'long', or as a
unified format diff:

So far, no problems.

Ok, I'm stupid. I realized right after I sent this, that I forgot a

Something I'm just curious about...

where <!--#sqltest name column=column_name type=column_type-->

VS.

where column_name = <!--#var name-->

Is the only advantage of using the first (sqltest) the type checking? I
can't find any other obvious advantages.

Butch,
Thanks for the reply - but this doesn't work completely either. I can 
add folders and delete them and the changes made show up in the 
listing, but adding documents (both documents and methods) has no 
effect. If I delete the *original* documents created by the 
installation, they show up as being gone, but even a copy-paste of 
the original documents doesn't get any new documents/methods etc. to 
show up.

Am I doing a dumb newbie thing here? (I *do* have a folder called 
'subFolder' btw).

many thanks
tone

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <19990309084120.83ca0fd9.in@mediamail.telinet.com>

Hi all,

I have been using python for years, and zope for a few months now (lovely),
ZServer for weeks, but Windows NT? Not long enough to understand the
differences between services and ordinary process (give me a break, I am
heavily from a Un*x background) :-).

I know when I installed the binary version of Zope on the windows machine
here it gave me a service in the services list which I can activate on
startup. However, I am betting that this runs the ZopeHTTPServer, not the
ZServer which I got as a separate download. I have everything working just
lovely with the ZServer now, but it needs to be run as an NT service (and
respond to start and stop signals, etc) at which point I freely admit my
own inadequacies in this area.

Now my question. How can I do what I need to do. Is it simply a case of
redirecting a python 'shell' file used by the service to the start.py in
the ZServer module, or is there more to it? If it is this simple, which
python 'shell' file do I use? If it is not this simple, can someone send me
basic instructions on how to do it (why is NT like this - give me an
rc.local file any day - I know where I stand with that stuff).

Thanks in advance.

Dick

Can you submit this problem you noted to the Collector as a

Zope-dev is the place to ask specific questions about Zope's API and
Zope Product Authoring.  Go ahead and ask your questions, the unsuported
just means we can't make any guarantees or commit company resources to
it, but if your question happens to use Confera as it's basis all the
better.  Someone out there might have the answer.

Hi All,

The DTML Example folder has been updated. I've incorporated the fix below,
but the reason that new documents were not showing up is that the page was
looking for the wrong 'meta_type' for objects in the subfolder. Up till the
last release, documents had a meta_type attribute of 'Document', but now
documents either have 'DTML Document' or 'DTML Method' as their meta_type.

Tony's problem was that Zope was correctly respecting the meta_type of the
'old' Document objects included with the demo, but any new documents added
afresh were being created with the 'DTML Document' or 'DTML Method'
meta-types, which were falling through the objectValues 'sieve'.

Here's the new version...

Cheers,

Andy.

I haven't played with it too much but I think that Zope handles undefined
variables properly if you do the sqltest.

ie.

where <!--#sqltest name column=column_name type=column_type-->
and <!--#sqltest name2 column=column_name2 type=column_type-->

will work if name2 is not defined.

It also handles the quoting and SQL syntax (such as doubling single quotes).

My guess is that you created your original database in Zope-1.9 and then
moved everything into Zope-1.10. If that is the case then you need to
replace
<!--# in "objectValues(['Document'])"--> with
<!--# in "objectValues(['Document','DTML Document','DTML Method'])"-->
or something to that effect.

Not quite.  ZopeHTTPServer is a console app just like ZServer.  The
service is a PCGI-like thing that runs Zope as a service, listening for
named pipe connections from something that is run as a CGI by the web
server.

ZServer is still at alpha 2 so it's premature to focus on things like
how it is packaged.  I *think* we have all the issues figured out and
the next release, perhaps this month, will be a beta1.  Until we get
into beta, we'll have to hope that someone in the community packages it
up as a service.

One issue off the top of my head is integration with the NT Event Log.

Absolutely...  we ran into some situations where the SQL was so dynamic
potential security problems arose.  sqltest and sqlvar are designed to
reduce that exposure.

Additionally, we've found a very common rhythm where a search UI might
expose all of a large percentage of the available data elements in the
RDBMS.  Using sqltest lets the user not specify one or more parameters
without a lot of messy <!--#if --><!--#/if --> stuff in the SQL Method.

I'll correct myself here. I was thinking of the <!--#sqlgroup ...--> tag. I
don't know what <!--#sqltest ...--> does that <!--#sqlvar name--> or
<!--#var name fmt=sql--> won't do...

I meant to bring this up in my earlier post -- this tag too, is used to
simplify what could be a terribly complicated SQL Method given an
indeterminate number and list of search criteria.

With this tag you can permit an arbitrary arguments to be supplied
connected with your predetermined ANDs and ORs

This one tag has, in the past, reduced may SQL Methods into one --
natural maintenance savings.

A _very very_ nice feature of #sqltest is the 'multiple' feature.  For
example:

SELECT * FROM inbox
WHERE <!--#sqltest doc_status type=string multiple-->

If doc_status is passed in as a single value, like "foo", the SQL statement
will be rendered as::

SELECT * FROM inbox
WHERE doc_status='foo'

BUT!!! (this is where it gets good), if doc_status is passed in as a
list/sequence, like ["foo", "bar", "drop", "ship"], it will be rendered
as::

SELECT * FROM inbox
WHERE doc_status in ('foo','bar,'drop','ship')

This is an _extremely_ handy feature of #sqltest.  Prior to #sqltest, doing
the above might be like:

SELECT * FROM inbox
WHERE doc_status in (
 <!--#in doc_status-->
 '<!--#var sequence-item fmt=sql-->'
 <!--#else sequence-end-->,<!--#/else-->
 <!--#/in-->)

(#else used to be used where #unless is used today).  The above code also
always required doc_status to be passed in as a sequence.  #sqltest is
smart enough (I believe - i've never been bitten by this) to detect the
difference between strings and lists.

I've used #sqltest with multiple many times with Acquisition where a folder
property would define part of a SQL statement.  That property in some cases
would be a single value, in other places it would be a tokens or lines
property.

So, in otherwords, you get the type checking, the multiple, the optional,
etc... with #sqltest that you don't get otherwise.  About the only problem
is that #sqltest currently doesn't do not-equals or "not in (...)".

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?

I bet your using a DTML Document.  Try using a DTML Method.  The reason
why the tree tag renders nothing for the DTML Document is because DTML
Documents are not containers of other objects, they are objects to hold
DTML content.  DTML Methods are (and this is the suble thing) *methods*
of the Folder object that contains them.  They are not 'objects' in the
same sense of the term used for DTML Documents (I can hear Jim saying
now "*everything's* an object").  Because Folder objects *are*
containers, the #tree tag used in a Folder's DTML Method will render the
contents of that Folder.  Hadar's example is a little outdated, it is
based on 1.9, in which DTML Documents didn't exist, and all Documents
were DTML methods.

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <006501be6a52$b0bbe900$fa01a8c0@rogue>

I currently have ZServer running as a service on two machines using the
srvany.exe tool from the NT resource kit or from MSDN.  Essentially srvany
is the actual service and then you tell it via registry settings what other
program you want to run.  It works good enough for me for the time being.

The only problem is that the service stop message does a hard kill on the
ZServer process so any last second updates to the Zope DB might be
fragmented if it wasn't finished writing, but with the way the DB works at
least the DB will still be usable.

I am out of the office right now so I can't provide step by step
instructions right now.  There is a .doc file that comes with srvany.exe
that I followed.  I specified that Python was the executeable to be run by
srvany, the ZServer directory is to be the CWD, and that the command-line
should be start.py.  Worked first try.

Of course the right thing to do would be to integrate native service
capabilities into ZServer itself via the win32api packages.  That way
ZServer could shhutdown gracefully and could send meaningful things to the
event log.  But srvany is good enough for alpha level, non-production
servers.  And I havn't had any problems to speak of dealing with running it
as a service.

Subject: [Zope] Images and Zope1.10.2
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC4A@peter.sths.org>

I have a nifty system whereby each individual I add to a database
automatically gets a personal directory and password. One of my users
has come to me with a problem. He can add images to his directory, but
cannot subsequently edit the image (i.e. open the image's manage screen)
as it complains about lack of permissions. The security role he has
contains all the image related options I see. He can delete it, btw.
This is not an immediate issue, but I do wonder why the permissions
don't seem to be working in a sensible manner. Why should he be able to
add images, but not manage them? Are there extra 'image manage'
permissions? If so, where do I find them?

Subject: [Zope] FAQ 0.2 - About this FAQ
Message-ID: <36E56988.CEF76199@pop.vet.uu.nl>

Zope FAQ 0.2 - About this FAQ and the Zope Documention Project

* What is this FAQ?

    This FAQ is a project of the Zope Documentation Project, and aims
    to answer any (or at least lost) questions you might have about
    Zope and how to use it.

* What is the Zope Documentation Project?

    The Zope Documentation Project (ZDP) is a community project of
    Zope users that aims to create documentation for Zope. The first
    goal of the ZDP is the creation and maintenance of an extensive
    Zope FAQ, later on other documentation will follow.

    We welcome everybody to contribute; for instance by sending in
    questions and answers for the FAQ.

* Where is the rest of this FAQ? 

    The Zope FAQ has been split into separate sections. If you are
    reading this on the ZDP mailing list, you should see the other
    documents posted as well.

    If you are reading this on zope@zope.org or zope-dev@zope.org, you
    will only see this message. The Zope FAQ is under development. It
    is probably already useful, but because I don't want to spam
    everybody you will have to look at the ZDP list to see the rest of
    the FAQ. Everyone is very welcome to join the ZDP list. 

    You can also wait until the ZDP has its web infrastructure going
    and the FAQ is published on the web. This will hopefully be very
    soon; we're working on it.

* How do I contribute?

    The Zope Documentation Project has its own mailing list
    (zdp@zope.org). You are encouraged to use this list for all ZDP
    related communications. Please do not send your messages (such as
    FAQ contributions) to Martijn Faassen (the current FAQ maintainer)
    if your message can be sent to the mailing list instead.

* How do I join the ZDP mailing list?

    You can subscribe to the ZDP mailing list by using the page::

        http://www.zope.org/mailman/listinfo/zdp

    Thanks in advance for your contributions!

* Are there other Zope-related FAQs?

    Yes, there is the "Zope Questions and Answers" at::

        http://www.zope.org/Information/QA/

    This is maintained by Digital Creations; currently it is the best
    place to look if you are brand new to Zope.

    That said, Paul Everitt of Digital Creations has kindly
    contributed the Zope Questions and Answers to the ZDP (or vice
    versa; the ZDP is contributing to the Q&A). The ZDP plans to merge
    the two FAQs shortly.

* What is Structured Text and what does it have to do with this FAQ?

    The FAQ is (currently) written in Structured Text, so you may very
    well reading the FAQ in Structured Text format (the double colons
    and the indented paragraph structure give it away). If you are
    just reading this FAQ you shouldn't worry about it. 

    If you plan to contribute to the ZDP we'd prefer it if your
    contributions were written in Structured Text, however. For more
    information see the Structured Text section of this FAQ.

* What are these FIXME comments I see scattered through the FAQ?

    If you are reading the ZDP mailing list or its archives, then it
    is the FAQ's editor (or possibly a contributor) who is not
    entirely sure about some details on Zope, and is asking people on
    the list to help figure it out.

    If you are reading this FAQ somewhere else, then oops, they don't
    belong there. Please send a message to the zdp@zope.org list
    telling us about it, and thanks!

* What other sections does this FAQ have?

  We currently have sections on:
  
      o DTML
 
      o Zope Administration

      o Structured Text
 
      o External Methods
   
      o Builtin Products

      o Product Development

Make sure the user's role has the "Change Images and Files"

I have a problem with authorization under Apache 1.3.3
I can go to introductory screen but I can't get to ./manage screen. I
get Athorization failed, and when I pres cancel I get the traceback
below.

I have put the lines (with modification reflecting my placement of
Zope.cgi) from doc/WEBSERVER.txt at the top of my srm.conf file. I
wasn't sure where to put it, since according to Apache documentation the
directive is not inherited. Later I copied those lines to Virtual WWW
section of www.sol.cz but to no avail.

What does the line "Zope configuration maps /Zope/ to the Zope.cgi cgi
script" mean? I thought that all I need to do is put Zope.cgi in my
cgi-bin, put the above lines into srm.conf, and restart Apache...

You can try it on http://www.sol.cz/cgi-bin/Zope.cgi. name is superuser,

Subject: [Zope] Root Folders and Names {Manager's Guide Update}
Message-ID: <02c001be6a6d$a24716e0$0201a8c0@hawkeye.bob.oc>

* How do I "name"  the *blank* root folder?

This is the same folder that is named "Plutonia" in 
the Zope manager's guide. 

Maybe the root folder has no name so
that if I go to  http://www.bob.com/  the 
"Folder at /     " will present index_html 
to requesting browsers.

If I did name it "plutonia" would it be accessible
both as
http://www.bob.com/   and as
http://www.bob.com/plutonia  ?

So maybe I don't need to "name" this root
folder.  If so, then the Zope manager's guide needs
to be clearer. In the fourth paragraph on page 12 
it says:

"...presuming that your ZOPE is installed at 
http://your.place.com/Objects and it's management
screen is at http://your.place.com/Objects/manage"

This does not follow through the document.
There is no folder named "Objects"

Maybe the document should say:

http://plutonia.com/ and it's management
screen is at http://plutonia.com/manage"

And to manage one of the three departments
used in the examples, say for 
example "News" then:
http://plutonia.com/news/manage"

Other notes on this issue: 
Timothy J. Grant asked:
"...My problem is that my Root folder in Zope has 
no name, and it appears that FSIMPORT requires 
a folder name for it to work."


No response was found to this post on 
the ZOPE list.

I've gotten Zope up and running on my IIS/NT server. Right now I can access it 
through www.myserver.com/cgi-bin/zope.exe. Is there any tricky way to get it to 
run as www.myserver.com/zope? including www.myserver.com/zope/folder/object?

Can you do that with Apache on NT?

I would use ZServer but I need to also be able to run Perl CGI scripts.

Right now you can't. And you don't need to. The "name" of the root folder
is simply the SCRIPT_NAME your webserver uses to access Zope. By default in
ZServer and ZopeHTTPServer this is an empty string, since they both
normally server one published module, though they both can server multiple
published modules.

So, you can give your root folder a title, but you can't use Zope to change
how your web server calls Zope. Do this with your webserver. In the case of
ZServer, check out the zope_handler.py, it has options to set the
SCRIPT_NAME. ZopeHTTPServer also has options to set the SCRIPT_NAME with
command line arguments.

Right.

>If so, then the Zope manager's guide needs
>to be clearer.

Perhaps the docs should be updated. The manager's guide probably assumes
that you're using PCGI, but it shouldn't make this assumption.

Hope this helps.

Message-ID: <Pine.LNX.3.96.990309162504.454A-100000@taos.kavi.com>

Is this behaviour a bug?

I have all my ZSQL methods collected together in a folder. If I call these
from a sibling folder[1] without any arguments, ie.

<!--#in "sql.company"-->

I get the below error, if I call them with specific arguments, ie.

<!--#in "sql.company(comp_id=_['comp_id'])"-->

I get no errors. (comp_id was in REQUEST in both cases).

[1] by sibling folder I mean something like the following arrangement...

/sql/company  		(where the sql method is stored)
/lists/company_list 	(where the call is made)

Here's the error:

<!--
 Error type:  
 Error value: 0
 -->

Traceback (innermost last):

Looking into it, line 332 in Aqueduct.py is a simple key lookup...

    def __getitem__(self, key): return self._data[key]

It would seem that an argument is getting passed in by default when the
sql in put in a parent's subfolder.

Message-ID: <Pine.LNX.3.95.990309165933.6532A-100000@animal.blarg.net>

I have been playing around with Zope/ZPublisher/DocumentTemplate and have
been extremely pleased with the ease of development, as well as the power
of the Python language.

Sometimes I have found myself wanting to save the results of an expression
in my DTML code, for use later in the same page (or even an embedded DTML
object).  The only thing I have used that is similar to DTML is
ColdFusion, which has a CFSET tag, ie: <cfset myvar = "test"> or
<cfset total = subtotal * tax>

In reading the docs, it looked like I might be able to do something along
the lines of <!--#call "REQUEST.set('var', 'value')--> but this didn't
seem to work, and it's not very elegant either.

Am I missing something? None of the howtos or tutorials seem to cover
this.  A <!--#set newvar=oldvar--> / <!--#set var="expr"--> would be
really spiffy. =)

Please make sure you CC me if you respond to this message, as I had to
unsubscribe due to the overwhelming amount of traffic.

Thanks!

Subject: [Zope] tree doesn't work 4me linux amd win32

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?



I had the same problem, but only with Zope 1.10.2.  I noticed that DTML
documents (the default to be created) won't work with the tree tag.  If you
create a DTML Method (like the old DTML from Zope 1.9) then they work as
expected.  I don't have a clue as to why this works like this.  Maybe its
the proerties of the DTML Documents that are acting folderish and tree
doesn't know what to do?

Hope that helps,

Message-ID: <4.1.19990309224955.009de8f0@10.0.0.1>

We have been unable to access properties of the new DTML Document objects
in the same way we used to access properties of Folders. 

I don't know whether we are doing something wrong or we found an
inconsistency in the new 1.10 Zope API.

Here is a very simplified test case illustrating the issue.

I have a folder with these contents:

folder1 [Folder]
- broken_html [DTML Document]
- index_html [DTML Document]
- sub-document (The Grand Sub-Document) [DTML Document]
- sub-folder (The Grand Sub-Folder) [Folder]

The source of index_html (which works) is:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-folder'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-folder'].author"--></p>
<!--#var standard_html_footer-->

This works as expected. The properties title and author of the sub-folder
are retrieved.

The source of broken_html is exactly the same, except for the sub-document
reference:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-document'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-document'].author"--></p>
<!--#var standard_html_footer-->

Viewing this document-method I get a "Zope Unavailable" message with this
traceback:

<!--
 Error type:  
 Error value: 'string' object has no attribute 'title'

So, how do I access properties of sub-documents from a sub-document in the

One way is to use DTML Methods instead of DTML Documents.

Nope, ZHS (for short) is derived from the example CGIHTTPServer.py that
ships with Python---it's heavily modified though.  ZServer is what is
derived from Medusa and is currently in alpha (though pretty stable for
me).

As for SSL, not currently, and I'm not sure what's going to happen with
this.  You can use Apache+SSL right now for this.  I've had some
thoughts about it, but I'm not sure how SSL will impact an async-socket
based system...  the setup of new SSL connections is kind of heavy.

I am using:
Red Hat 5.2
Zope 1.10.2

- I created a username of "zope_u" and a group "zope"

- I did run the installation script with a command line like:
        ./install -sAdmin:MyPassword -u zope_u -g zope

- I created the Feedback and SendFeedback forms as per the manuals.

- I added the user "zope_u" to the mail group.

- I modified user zope_u's .bash_profile file to include the path to
sendmail in /usr/sbin

- If I log-in to the Linux server as zope_u, I _am_ able to call sendmail
and to send mail outside of the server.

Anything else I missed, folks?

Regards.

I understand the difference between DTML Methods and DTML Documents. 

The very reason I chose to do it with DTML Documents was to be able to
store some special fields, such as 'author' in my example, along with the
document. I cannot do that with DTML Methods, as they do not have properties.

In Zope 1.0.9 I used folders but I was running into problems with relative
links. It seemed natural to switch from my previous folders to the new DTML
Documents.

I still do not know to reference the properties of a DTML Document 'A' from
within a document or method 'B' in located in the same folder as 'A'.

Thanks for any help.

You are right. I was using folders too for the same reason.

You can use the PARENTS variable.

so if you have a folder which contains two DTML Documents A and B then
you can access B's properties from A by:
<!--# var "PARENTS[0].B.name"-->
PARENTS[1] will return the folder or containing object one level up and 
PARENTS[-1] will return the top most Folder.

Thanks for your help, Pavlos. I found another way. Instead of writing:

<!--#var expr="_['sub-document'].author"-->

I wrote this, and it worked fine:

<!--#var expr="_.getitem('sub-document').author"-->

I found a way, but I don't understand why the first syntax worked fine with
Folders and fails with DTML Documents. If anyone would like to clarify the
semantic difference between _['sub-document'] and
_.getitem('sub-document'), I would be even happier.

By the way, Pavlo's site http://www.gaaros.com:9673/ is useful!

The answer is in both the ZDP's FAQ and the DTML Manager's Guide. 

_['foo'] "renders" foo according to DTML rules. This process mostly
consists of calling DTML and other callable objects.

_.getitem('foo') simply returns foo as found in the DTML namespace.

The reason you were having problems is that _['sub-document'] renders the
document to a string. Naturally strings don't have properties. Hence the
error you got from Zope, "'string' object has no attribute 'title'".

Make sense?

Subject: [Zope] Another "no such file" failure...
Message-ID: <Pine.BSF.4.05.9903092345060.330-100000@guru.phone.net>

I'm trying to get zope working to study it, but keep stumbling over
the "(102) failure during connect" error - with the "No such file or
directory" addendum.

The underlying OS is FreeBSD 3.1. I want to run it on an Apache web
server (at least for now), with the server doing the
authentication. That all appears to be working properly - after all,
I'm getting errors from pcgi, now, right?

The var directory is writable by nobody. In fact, the entire source
tree is owned by nobody, which is the user that the Apache httpd is
running as. However, I get log file entries from pcgi, even after
deleting the pcgi.log file. I initially tried copying the Zope.cgi
file to cgi-bin, but noticed that some (unspecified) setting in
Zope.cgi might need to change because of that, so I added a second
scriptalias to the Apache httpd.conf pointing at the source directory,
set the protections on it, and tried to load <URL:
http://localhost/Zope-bin/Zope.cgi/manage >. No change - the log file
records the same error message.

The pcgifile.py test reports 

	error attempting: 'from cgi_module_publisher import publish_module'

This doesn't appear to exist in the distribution - and I recalled
something about that being a holdover from bobo, so I removed that
test from the script, and ran it again. The modified version runs
cleans.

Was I wrong about cgi_module_publisher? Should it be finding that? If
not, then what's the next thing to look at?

FWIW, here's the entry from httpd.conf section for Zope:

SriptAlias /Zope-bin/ "/home/mwm/external-src/Zope-1.10.2-src/"
<Directory "/home/mwm/external-src/Zope-1.10.2-src/">
	AllowOverride	None
	Options		None FollowSymLinks
	Auth_PGhost		sql
	Auth_PGport		5432
	Auth_PGdatabase		web
	Auth_PGpwd_table	users
	Auth_PGuid_field	name
	Auth_PGpwd_field	password
	Auth_PG_encrypted	off

	AuthName		"Zope"
	AuthType 		basic
	require			valid-user
</Directory>

And here's Zope.cgi:

   You don't need hostname and port part, so the connection string can be
just "baseball user_name".
   (BTW, without host:port, libpq will connect to postgres using UNIX
sockets, not TCP/IP. I think it is much better - for speed and security)

I've got an external method that is generating a (possibly quite large)

in a big string, then returning it to zope. I'd _like_ to be able to just
have the external method send the data straight through (maybe in chunks)
without having to read it all into memory. Is this possible with zope
at all?

Because you are calling "sql.company" (in quotes), it is assumed to be an
expression, and your expression is referencing an attribute, not a method.
Try using the following: "sql.company()", or sql.company (without quotes).
Note: I didn't test either method.

MailHost doesn't use sendmail, but rather opens a socket to the specified
sendmail host and uses the SMTP protocol to send the messages. This is
somehow prohibited. It looks like there is maybe no SMTP server listening
on the specified address and port, or your machine is not allowed to
connect. You could try and do a manual telnet to the address and port from
the zope_u account and see what happens.

Make sure you also go through the motions, like HELO <hostname>, and such.

Can #sqltest handle the 'wildcard' situation in MySQL (and probably 
other DBMSs too)

select * from tbl where tbl_val like '%nib%' is a different SQL query from
select * from tbl where tbl_val = 'niblet'

my attempt...

select *
from tbl where
<!--#sqltest tbl_val type=string multiple-->

I think the first problem will be finding a publisher that streams.
PCGI buffers all I/O, perhaps FastCGI doesn't.  Even if you didn't,
sending it through Zope in chunks would avoid getting Zope's memory
footprint up there.

One way would be to have the ExternalMethod return a sequence, then do
something like:

<!--#in myExtMeth-->
  <!--#var "RESPONSE.write(sequence_item)"-->
<!--#/in-->

Of course the above might be completely wrong, but you get the drift :^)

Hi all,

I have tried _['answerbtn.x'] but I get a traceback from Zope.

Yes, it's a holdover from Bobo days (which some people are
still using for existing apps) but you can ignore that
particular error.

Contact me offline and we'll try to get this resolved.

Try::

   <PRE><!--#var REQUEST.form--></PRE>

or::

   <!--#in "REQUEST.form.items()"-->
      <LI><!--#var sequence-key-->: <!--#var sequence-item-->
   <!--#else-->
      No form items
   <!--#/in-->

To generate an overview of all form variables your DTML has access to.

Thanks for the suggestion Martijn but I've already tried that and it does
indeed show variables of the form 'answerbtn.x'.  But when I try to access
them using one of:

<!--#var answerbtn.x--> or
<!--#var _['answerbtn.x']--> or
<!--#var _.getitem('answerbtn.x')-->

I get a traceback error, so I am none the wiser 8^(

Thanks anyway

Any other ideas?

Nope.  ZopeHTTPServer is not Medusa, it is based on the HTTPServer that
comes with Python.  Medusa is it's own product, that we have integrated
parts of into ZServer (which uses the core of Medusa to drive it's
network end).

http://www.nightmare.com/medusa/

For medusa info.  http://www.zope.org/ for info on ZServer.

Once ZServer is stable (it is alpha at the moment) use of ZopeHTTPServer
will be depreciated (but not forgotten).

Subject: [Zope] New subscriber: Installing Zope
Message-ID: <199903101525.KAA25149@mail.howard.k12.md.us>

Having seen Zope recommended on Usenet last week, I decided to check it 
out, Monday I found the Webreview article in the email box.  I have been 
reading as much as I can find, but one question is always on my mind, 
when ever I find one of these wonderful, does it all systems.

Can I install it ?  Not, is it to complicated to install, but do I need 
root access to the machine to install this application.  This question 
and the answer have killed many a promising application (DB & BBS).

So, the question is, can Zope be installed in a typical Telnet account ?

The install docs mention, you have to be root user, to install some 
components, does this mean what I fear it means ? (machine admin, ie. 
super user)

Yes.  I am trying to reference a folder that is not in the same path.
And I tried your next suggestion a long time ago, with no luck. 
<!--#var candidate1.name-->, and get an error with traceback:

<!--

This doesn't work.  My paths are like, /staff/candidates/candidate1, and
staff/companies/company1/job1/submission1/MyDocument.  I am trying to
reference a property of the candidate1 folder in the MyDocument
document.

Hmm,

More on the image button saga.

It seem's that <!--#var answerbtn.x--> does indeed work, but <!--#var

Seems weird to me, any ideas?

You should be able to install a binary package as a typical user on a
UNIX machine.  If your machine already has Python 1.5.1 or higher
installed (don't they all?!?!?! :-) then you can just install the basic
source distribution of Zope and do the:

	$ python wo_pcgi.py

Thing :-)  You can then use the ZopeHTTPServer on a untrusted port (over
1000) and off you go :-)  If you want to use Apache+PCGI you probably
will need administrator support, and if yo uwant to be on a port under
1000 you'll need it.

You should be able to get a feel for it without being root.

Try Zap, the precompiled apache for Zope (Linux only).  The zap.conf
file will probably have something your not including in your apache.
also, do an 'httpd -l' and make sure you have mod_rewrite compiled
and/or dynamicly loaded in.

<!--#var "candidates.candidate1.propertyname"--> will work.

candidates is the object that is the common ancestor, and from there you
can reference objects down that path. You will have to place the expression
into quotes, however.

You can indeed install it. I had originally had a standard telnet 
sort of account on a FreeBSD machine. You can basically get a 
full-featured Zope if your web provider runs apache with mod_rewrite.
(If they don't have mod_rewrite, authentication is a little bit more
of a headache.)

The thing to beware of is that PCGI starts a long running process
and many hosting companies will not be pleased about this.

Zope 1.10.2

I have a ZSQL method for inserting data into the database.
The database connection is active.
the permissions are correct.
the method is defined roughly as:

insert into tblname (col1, col3, col4, col5) values
(col1val, "value taht is constant", col4val, col5val);

when I try and test it, Zope tells me that there
is a parse error near ';'.

I remove teh ';' and Zope tells me that 
"This was not a query."

I'm missing something, and I'm hoping it's not my 
mind . . . any help?

(oh, nad yes, the query works just fine when entered
by hand in a mysql or xmysql connection)

Subject: [Zope] title and id properties in DTML methods
Message-ID: <36E6A70C.687B26BA@pop.vet.uu.nl>

Hi everybody,

I'm probably completely confused, but if I understood it right, DTML
Methods in Zope 1.10 are the same as Documents in Zope 1.9. I may
remember wrongly, but wasn't it so that

<!--#var title_or_id-->
<!--#var title-->
<!--#var title-->

in 1.9 documents rendered the title and id of the actual document, and
not that of the containing folder? In 1.10 in DTML methods, they appear
to render the containing folder, instead. The only way I can access
title of a DTML method in 1.10, is by referring to it specifically, i.e.
<!--#var "some_method_id.title"-->.

It works as expected with DTML Documents.

Is this as it should be? Am I correct about the 1.9 behavior? If so,
then DTML Methods don't seem to be exactly equivalent to 1.9 Documents,
and this should probably be in the FAQ. :)

Regards,

Martijn

Do it without the ';'. When it says 'that was not a query' it simply
means that there was no returned results for it to display. If you check
the database, the values should have been successfully inserted.

If you're doing just a single query, you don't need the ';' (or its
equivilent).

If you're doing multiple queries, use <!--#var sql_delimiter--> to seperate
them.  The DA will seperate the queries using this.  This is equivilent to
what command line or other SQL tools often do with the ';' character.

> I remove teh ';' and Zope tells me that
> "This was not a query."

Nothing is being returned is what this means (or more basically, it wasn't
a SELECT based query).

I can't use another apache just for Zope. I looked into zap.conf and
incorporated some changes into my httpd.conf. No way.

Since the log file of RewriteLog remains empty, I believe no rewriting
takes place, actually. I have about 30 virtual servers on that httpd,
maybe there lies the problem? Also this is Apache 1.3.3, do I need
Apache 1.3.4?

hi!

No. Zope works fine with Apache 1.3.3. Did you remember to set the ExecCGI
option? And did you remember to turn the RewriteEngine on?

Yes I turned rewite engine on, but maybe not in the right place. I wrote
it into global config.

I believe do not need to use ExecCGI, since I use ScriptAlias. And
Zope.cgi gets executed, I otherwise wouldn't be able to get to Zope
introductory. 

I'm desperate....

Something in an external method similar to this should do the job.

from string import split, join

def stringtounderscore(str):
	return join(split(str," "),"_");

which is then called from your page as 
<!--#var "stringtounderscore(mystring)"-->

Alternatively, if this is something you only need occasionally, you can
code it directly in DTML...

<!--#var "_.string.join(_.string.split(mystring,' '),'_'"-->

Both of these are untested, but I have tested the join/split command in
python directly:

>>> join(split("this is a test string"," "),"_")
'this_is_a_test_string'
>>>

You can use something like:

<!--# var "_.getitem('foo',0).whateverproperty"--> (Is 0 the default?)

_.getitem('foo',0) returns a reference to the object with id foo.

Thanks for a very fast reply, however it doesn't work. I'm still getting:
Error value: 'string' object has no attribute 'title'.

This is what I'm trying to do:
A DTML document (index_html) has a property art1 which has an ID for another
DTML document as value (type: string). In index_html I use: <!--#var
"_[_[('art1')]]"--> which renders the article. I can of course use
<!--#var title--> in the actual article, but I rather don't. So I'm still
banging my head in the wall after hours of trying to accomplish this. Can it
be a bug with DTML documents??

I think that DTML Methods (or Documents?) are meant. They are like
methods to the folder objects that Zope publishes. Look at:
http://localhost/Zope/foo/bar/doc as asking Zope 'okay, folder 'foo', I
want your subfolder 'bar' (this could be seen as using a method on foo
to request 'bar'), and then I want to view 'doc' (which is, let's say, a
DTML method) in bar. 'doc' in that case is a method of the bar object,
which, when called, returns HTML code (to the browser).

An *external* method is a method which comes from outside the Zope
object database (though it's loaded into it, and behaves just like a
normal internal method).

If all this talk turns out to be correct (somebody tell me or send
corrections), then I can turn this into a FAQ entry. If anybody else
feels like writing this up in a nice way for the FAQ (Oleg?) that'd even
be better. Just send your contributions to the ZDP list.

Regards,

Martijn

Hi!

   That is, there are DTML Scripts and External Methods. Python code is
used in External Methods and Products, but never goes into Object Database.

I think it's true Product python code doesn't go into the Object
Database, but I'm unclear about what happens with External Method python
code. You need press the 'edit' button for an external method in Zope
each time you changed something in it and want it updated. This would
imply Python code can indeed be part of the Object database, right?

I can confirm this; this one bit me too, I recall. Can anyone write up a

FAQ document on Apache with Zope too, what's the status on this?).

Actually not. For security reasons the code of an External method does
not reside in the Object Database but in the filesystem. When you press
the 'edit' button the code is read and evaluated and it is the evaluated
code that is stored in the Object Database. There was a thread about
whether the source code should be included in the Object Database but I
think thge Digital Creators were not convinced.

How are more than 1 value submitted from a form? How can I get those values

argument?

Help is much appreciated!

No, it forces Python to recompile the code. The code itself is NOT stored
int the object database. Only instance data is stored in the object
database, no code is. Zope classes are said to change all this, aren't
they, DC?

Pressing the 'edit' button "reloads" that particular External Method code
into the system.  It's not stored in the database at all - the External
Method object you add/edit through the Zope management screens is primarily
a pointer/wrapper to a method in a module in the Extensions directory.  The
Edit button in essence acts similar to the reload(module) function in
Python.

Basically, Zope (and Python) don't have a way of knowing the code in a
module has changed unless it's explicitly reloaded, which is a good thing.

Well this is how I understood the process.

Basically the code is read and exec-ed and the the func_code
func_code.co_varnames are extracted. Then they apply all the clever tricks
to turn the function into a valid Zope method, by (I assume) creating a
Zope method and replacing its func_code and the associated func_defaults
and arguments with the ones extracted from the external function.

The relevant code can be found in
Zope/lib/python/App/Extensions.py and
Zope/lib/python/Products/ExternalMethod/ExternalMethod.py

links to the same page being viewed, but passes a value to
standard_html_header/footer that is used to _not_ render the surround Zope

External Methods are (to the best of my knowledge) evaluated and their
compiled code is kept in process memory (effectively cached) the first time
the object (the External Method object pointing to a particular
module/method) is activated.  It is removed from process memory when the
object is de-activated.

This is kindof a tricky process and may be effectively cleaned up in the
near future so I won't go into too many details here.  An important thing
to keep in mind is (again, this may change soon) that the compiled code is
kept locally in each External Method Object.  If you have two EM's in Zope
pointing to the same code, you have to use the "Edit" button on _both_
External Method objects to effectively reload it.

Hi!

Just made a small test-site, and followed the Zope magager guide to how to

by default everyone should have access to view the contents of a site made
by zope, but here the authorization/authentication dialogue pops up whenever
someone try to access the site. Cancelling username/passwd just ends in

apache handles the authentication bit, but still - shouldn't it let
'anonymous' trough? I've had a look at the security settings for both

When you say that you made it so that Apache handles the authentication,
I take that to mean you have created a .htaccess file? If that is the
case, Apache will always prompt for the password and check it against
your password file. If you use mod_rewrite to let Zope handle authentication,
you will not see the password prompt for resources that are available
to anonymous users.

Hello Zopesters:

Are you confused by the subtleties of DTML? Want the skinny on advanced
DTML tricks and gotchas? Check out my advanced DTML HowTo:

http://www.zope.org/Documentation/HowTo/DTML

This document explains in detail the concepts behind advanced DTML tricks
like indirect variable lookup, setting variables, calling sub-templates
with different client objects, etc. Its main emphasis is on understanding
how DTML uses a namespace stack to manage variable lookups.

Enjoy and send me your feedback.

-Amos

P.S. Probably at least some of this material will be incorporated into the
DTML User's Guide in the future.

Thanks! Although by now I knew most of what was mentioned (though it

Message-ID: <Pine.LNX.4.04.9903111551260.32022-100000@dolemite.psionic.com>

Hello,

I've looked through all the docs, FAQs and threads of the Zope list for
some of these answers and haven't found a clear method described. I'll
apologize now if the questions seem obvious, but I'm new to deploying Zope
on a web server and need some initial Zope setup guidance.


Question 1: 

Under Zope, what is the proper way to configure the website so users can
simply go to http://www.example.com instead of:

http://www.example.com/example
http://www.example.com:9673/
etc.

My understanding is that the mod_rewrite rules will have to come into
effect here. Will I also need to do a re-direct of some type? I need
some way to direct all URL requests so they are re-written to point to the
correct Zope folder. The ideal for me is to have a series of folders in
Zope that contain separate websites. The sites can be virtual hosted as
needed (although right now I'm only running one site). I can't find a
clear description of how to make this happen. Also I don't want to run a
separate Zope process and proxy people to the port. I want to have
everything running on port 80.

I'll have to agree with other posters that a tutorial on the design of
the actual Zope site with Zope would be very helpful as they are using a
layout of html and hierarchy that is very similar to what I'm pursuing. In
fact if someone could provide me with a description of the config they're
using it would be a huge help.


Question 2:

Under .DTML construction of links is it generally considered "better"
Zope practice to reference the entire URL or the Zope object hierarchy
directly?

Question 3: 

I don't want tracebacks to appear under any circumstances to the end
users. I haven't tried anything to counter this yet, but wanted to know
what some others have done. Would an approach to this be a try/except
positioned in the standard_html_header and footer files? Ideally I would
like to catch all exceptions and have it automatically mail the exceptions
to the webmaster instead of showing the user (In fact I think this would
be a good feature for the product). 

Question 4:

Has anyone pursued a security audit of the Zope code? I've been
considering doing this (not that I don't trust the Zope developers,
it's just that I don't trust anyone) and would like to work with
others if possible. Several of the sites I admin get hacked on very
frequently and I'm a little nervous about replacing static web pages with
no CGI running anywhere with the exact opposite end of the spectrum with
Zope. :) 

I'm also going to prepare a document describing how to run Zope
in a chroot() environment under UNIX to increase security. I'll let the
list know when it is complete.

Thank you for any responses,

-- Craig

It seems to me that the www.zope.org is rather slow this week.  Documents
are taking far too long to be parsed.  Pings seem reasonable, so I am
expecting that the server may be receiving a lot of requests and being
overloaded (maybe from the Web Review article).  So I am just wondering what
the specs of the system that the www.zope.org ISP is using.  Also wondering
about stress tests and benchmarks for the Zope system.  (It must also depend
on backend systems etc)

Use Apache's VirtualHost ability...
Look here for more info: http://www.apache.org/docs/vhosts/
An example:

# in httpd.conf

# your ip
NameVirtualHost 192.123.44.3

# your standard host.domain (this must come first)
<VirtualHost 192.123.44.3>
ServerName your.standard.name
DocumentRoot /home/httpd/html
</VirtualHost>

# one or more extra virtual hosts
<VirtualHost 192.123.44.3>
ServerName your.zope.name
DocumentRoot /home/httpd/html
RewriteEngine on

1) How do I get Zope to run as a service on my NT box so I dont have to

I'm the guilty party (!)

I found this problem before but so far haven't found the fix.... here's what
I originally posted to the list.

I'd like to get this sorted out as I'm also working on a Souped (Zoped?) up
version of Amos's poll product, which produces pie-chart gifs in response to
the poll results, but it also broke in much the same manner going from 1.9
to 1.10. So any help on this matter would be much appreciated!

Cheers,

Andy.

Subject: RE: [Zope] Guestbook Product


I get the same thing :(

Hmm.. looks like DocumentHandler no longer exists.

I've taken out DocumentHandler from the Guestbook, to mimick the change that
has been made to 'Folder' going from 1.9->1.10. When doing the guestbook, I
kept making sideways glances to Folder.py to see how it was done ;)

The book no longer crashes but I'm getting some other wierdness. The
guestbook is a folderish product which contains two documents that the user
can add to change the appearance of the guestbook. They're added by the
following lines in the 'add' method ...

        # Add a Document used to view previous entries
        fileName = os.path.join(prefix,'index.dtml')
        index2 = open(fileName,'r').read()
        i = DTMLMethod(index2,__name__='index_html')
        print "i is %s" % i.meta_type
        i.title='Change me to determine how entries are viewed'
        self._setObject('index_html',i)
        print "ObjectItems is %s" % list(self.objectItems())

The added objects no longer seem to be showing up in objectItems().

The debug statement, when run on 1.9 prints out the newly added object in
the call to 'objectItems()', while on 1.10 it returns an empty list. Is this
a side-effect of the removal of DocumentHandler? I thought that _setObject
was being inherited from ObjectManager, so wouldn't be affected by the
removal of DocumentHandler.

Cheers,

Andy.

Well, under RedHat 5.2, mod_rewrite is a DSO, and is activated
in the *middle* of the httpd.conf.
I had the same problem. The rewrite rules put a the top of the file
have no effect because they occur *before* mod_rewrite is activated.

I had to put the rewrite rules a the end of the file.
I works now.

I don't know if this will solve your problem, but, just in case...

Message-ID: <00a401be6c5d$caec6180$147800a0@pc-pi0>

Hello,

Correct me if i'm wrong: one has got to have "access content informations"
permission to be able to write:

<!--#with Folder--><!--#var title_or_id--><!--#/with-->

right? I've been bitten with that, and once i gave "access content
informations"
to the Anonymous User, my problem went away.

Also, before I submit this to the Collector, is it normal that the "use
mailhost services"
doesn't appear in the security tab of the folders? Each product has its
permissions
that are listed, but nothing with the mailhost object.
I had to change it directly in the mailhost object.
If it's normal, it means that i can't give global permission for mailhost
objects???
What confuse me, however, is that the mailhost object claims to "acquire"
permission
settings from its parents, but nowhere in its parents i can define the
permissions.

Hi all ,

We try to use DocumentTemplate not for HTML dynamic generation but for
C++ generation. For convenience, and because we are familiar with Python
we intend to use the Alternate Python String Format Syntax. The
generation code is beautiful compared to our previous output.write("blah
blah.... ") instructions.

Reading the docs, looking at the Zope site, this behaviour doesn't seem
to be shared by a lot of zope users. Moreover the Alternate Python
String Format Syntax  is poorly documented, and DTML features seems to
be usable but the way they can be used seem very strange. Basically our
needs are to use conditional structures, iterative structures and to
call methods. The last point seems to be the hardest one. The following
code shows a way to call python methods in python strings but 3 persons
during half a day have been necessary to find it out.

I suppose you can imagine my questions :

Is there a natural and convenient way to find out PSFS expressions going
from their DTML equivalent  ?
Is there a complete documentation on PSFS syntax ?
Are the features of DTML and PSFS identical ?
And the most important :
Do you encourage us to keep on using PSFS instead of DTML ?

Thank for your help
Stephane

Well you were both right. I have turned on ExecCGI for my standard
cgi-bin directory, where I placed a copy of Zope.cgi. It is NOT
neccessary to add <Directory> statement for /usr/local/zope/ (I thought
it was neccessary... so I'm writing it here for the upcoming FAQ). Also
I thought that I should use http://www.domain.com/cgi-bin/Zope.cgi
address, which brings the introductory screen (that fooled me) but does
not allow authorization. The correct address is of course
http://www.domain.com/Zope, since that's what the rewrite rule is about. 

Thanks to all who helped me!

Hi Ron.  Just a guess, but how about having the tree tag pass in the the
current level as an argument to the same SQL method, then have the SQL
method adapt itself based on the argument?  Remember that an SQL method
can embed logic and act like an object using DTML.  For instance:

<!--#if "level==1"-->
  select ...
<!--#elif "level==2"-->
  select ...
etc.

The installer for the Zope NT binary asks you if you want to run as a
service -- in fact, that's the default.  Take a look at the file
"doc/INSTALL.txt", under Installation on Windows, for more information.

Unless we do something wrong, nope.

I'm not sure if the Zope universe is big enough yet for that.  I rememer
Guido doing this for Python about a year ago and nobody showed up. :^)

Perhaps if there were coordinated events?

I think the answer will certainly be yes.  Go to:

and do a search for Dreamweaver.  There are about 18 hits.

I do hope there is. If implemented like the Apache JServ module
(http://java.apache.org/) it should solve a lot of problems for everyone,
adding performance to boot.

JServ is in effect a separate process (like Zope) that receives it's
request via the Apache server, with the help of a module, that translates
the requests into socket calls.

If someone modifies the module that comes with JServ to call the Zope
process instead of the JServ process.....

Subject: [Zope] Getting slashdot to work...
Message-ID: <v04104809b30eccb7e1ff@[128.240.198.13]>

HI all,
In my quest to figure out how Zope works, I'm starting with ExtrenalMethods.

I've moved slashdot.py into Extensions and set up an external method 
(id: get_headlines, funstion name: get_headlines, python module: 
slashdot).

My 'calling' DTML is a method (slashdot_headlines) with the following;
<!--#call get_headlines-->        
<!--#in headlines mapping-->
<p>
<a href="<!--#var href-->"><!--#var title--></a>
</p>
<!--#/in-->             
trying 'view' on this method gives the following;
<!--
 Error type: 
 Error value: read-only buffer, class
 -->
...
<!--
Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module
  File lib/python/ZPublisher/Publish.py, line 590, in publish

    (Info: ((), {}, ('headlines', 'headlines_date', 60)))
TypeError: (see above)

-->

I *did* have a problem with using a proxy, but got around that by 
adding this line to slashdot.py (just before the urllib.urlopen() 
call).
urllib.URLopener(proxies={'http': 'http://cache-box.you.domain:your_port'})

What am I doing wrong?
many thanks

A mod_pcgi Apache module has been discussed.  It would certainly
be more efficient.  One of the issues would be whether pcgi
should get out of the process launch business, which would
simplify a mod_pcgi and make it easier to debug.

Ok, I'll check that out.  My experience has been than I run it with
start.bat and when I close that ms-dos window zope stops.

I think that now that zope is "out there " and is open source that you will

Perhaps a news.zope.org newsgroup would be cool as well.

If your external method is called from DTML document 'foo' then something
like this should do it (untested):

def mymethod(self):
	if not self.hasProperty('myproperty'):
		self.manage_addProperty('myproperty','hello','string')

BTW you can achieve the same effect from DTML

<!--# unless myproperty-->
<!--# call "manage_addProperty('myproperty','hello','string')"-->
<!--#/unless-->

This is a buglet in ExternalMethod where an exception has been raised and
caught by ExternalMethod, and EM is looking at the values of the traceback
for some special conditions.  It's trying to do a string.lower() call on
one of the values that in Python1.4 was always a string, but in Python1.5.x
is an instance (in Python 1.5, standard exceptions became classes).  This
has been fixed and will be in the next release.

Welcome to the list Andrew! I'm glad you found my suggestions
interesting enough to check Zope out. Regarding my last email, did you
figure out how to do PUT and GET from DW yet? And do you know if
Macromedia is going to add WebDAV support to DW?

In case you missed it, I'd like to point you towards the Advanced DTML
Howto:
http://www.zope.org/Documentation/HowTo/DTML
as that has more thorough information than the DTML guide I showed you
before.

I would also be interested in a newsgroup, as I am currently filtering
the email into a folder and sorting it by thread, but a newsgroup would
let me see the the same threaded view from home, as well. This would
also have the effect of letting new users see the context of the current
posts.

Subject: [Zope] Access Control Advice
Message-ID: <Pine.LNX.3.96.990312123932.13260A-100000@taos.kavi.com>

Hello all,

I am working on a Zope app, and would like to see if anyone has any tips
for how I should handle access control in this situation...

The site is a corporate organization site. It has many corporate members,
each has an admin which has control over a subset of information kept in a
relational database.

I want to have just one role (comp_admin) for this. But each company can
only have access to their company info. Thus I need to check that the
admin belongs to that company. (there are also regular users who also have
to login. they can view, but not modify)

The users, passwords and roles are kept in the database too (UserDB).

Each company has a unique id, and this is the primary keys in the DB. Each
user is associated to the company using this id (a field in their table). 

Make sense?

My current idea is:

1. Have a general main page which both users and admins login to. If they
use the admin login, get their company id (comp_id) and create a link to
the admin section using the magic of direct traversal (this way they can
bookmark the admin page). Eg.

<a href="/comp/1/admin/">admin section</a>
('comp' is the zsql method, 1 is the comp_id, admin is the folder)

Thus the comp_id of the company will be available, and I could:

A. I could then (mabey?) use the comp_id in the UserDB query (in the admin
   folder) to only retrieve those people belonging to that company.

OR (if I can't get to the comp_id from the UserDB query).

B. I could then compare to the person's comp_id to the company's comp_id 
   in each of the effect pages via a new standard_header.

Thoughts? Better ways to do this?

I haven't tryed this but on pg 10 of DTML Users Guide check out:

maketrans(FROM,TO)
and
translate(S,TABLE[, DELS])

it seems to do character for character translations.

Brian built a pretty cool way to hook SQL entries to particular
folder trees for the PDMS.  Each folder has a uniqueid which is
stored in a sql table, along with the folder parent heirarchy, when
an item is added to the SQL database.  This allows each folder to
easily identify which SQL entries belong directly to it and which
SQL entries belong as children.  This allows one to easily do things
such as count the number of SQL items which are identified with a
folder tree using SQL query syntax.

Brian also provided dtml methods to move folders and their
relationships around in the Zope heirarchy quite nicely. The
mechanism holds quite a few SQL items in it and there has never
been a need for a Python or SQL god to do any maintenance on the
system at that level.

However, it does use both SQL and External Methods. So, don't
believe that just because something requires a fairly deep level
of competence to create that it requires that same level of competence
to maintain (me for example :^).  That's simply one mark of a decent
implementation.

Message-ID: <9903121826.ZM7584@saab.coinet.com>

This may be a newbie question, but I've loked thru the doc and didn't
spot any obvious way to do this, short of an External Method.

What I want to do is given a limit number, iterate over a sequence of
DTML commands. This would be an obvious use for #in (which I'm using
elsewhere for other things) except I don't have a sequence - just the
number of items in the sequence, as it were.

In psuedo-code, what I'm after is something like this:
	for (i=0; i < <!--#var max_items-->; i++)
	{
	  // some DTML/HTML code using "i"
	}

Now if, given a #var, I could get a list - e.g.:
	<!--#var max_items--> --> list = [0, 1, 2, ... max_items]
or [1, 2, ... max_items], it doesn't make much difference.
then I could just use:
	<!--#in list-->
	// some stuff using <!--#var sequence-index-->
	<!--#/in-->

Is there an easy way to do this? Is there *any* way to do it?

Message-ID: <Pine.LNX.4.04.9903122303421.21162-100000@zeus.carolina.rr.com>

I am working on a web site for a local outdoors group. They have about
1,000 members and are growing fast, but their web site needs help. I had
lunch with their leader today, and strongly advocated the use of Zope to
redo their entire web site. He loved my ideas, and gave me the go ahead on
the site.

Now, my first question (I'm sure I'll have many) to the group is: How do I
create user profiles? Each user of the system needs to have specific
information associated with them including: full name, address, telephone
numbers, a picture (gif or jpeg, easily uploadable by the user), their
interests, a history of the events they've sponsored and/or attended, a
buddy list (basically just a collection of other member ids), and so on.

I have downloaded the UserDb product, and figure I might be able to extend
it to support the extra columns I require. However, a big part of me wants
to keep as much of this in Zope as I can. I like the idea of the
objectstore, and don't necessarily like having to fudge SQL tables every
time I add or remove an attribute from the profiles (not that I will be
doing that, necessarily).

What do those with a higher Zope Zen Rating than I suggest in this
situation? I'm also going to be making an Events Calendar, which is
connected up with all the User information (who's running the event, who's
signed up to attend, etc.). Is all of this something that Tabula would be
good for? If so, who do I have to sleep with to get it? :^) 

I am willing to write up a case study, testimonial, contribute any code I
write back to the community, etc., whatever is requested. I just want to
do a good job for these guys, making myself and Zope look good in the
process.

HELP! *grin*

There is no direct way for Dreamweaver to send pages back to Zope

webdav yet).

So my question is this - when will we get ftp support in zope? (not just
alpha).

I am looking at the dtml spec right now and thinking about building

One thing I need is for someone on the zope team or elsewhere to help me

Recent notes about Lynx notwithstanding, I agree.  It's extremely
frustrating when debugging the security of an app!  Zope _CAN_ use a
cookie-based authentication scheme with the UserDB product.  UserDB uses
Database Adapter (e.g., Oracle) to connect to a store of user info
(e.g., userid and password).

I can imagine some motivated community member taking a look at the
current incarnation of UserFolder and UserDB and cookie-ifying the
UserFolder.

Since DTML already has at least two different syntaxes, would it 
be hard to give it another one, that used 'regular' tags? For getting-
user-acceptance purposes it would be really good to work with as 
many HTML editors as possible, even lame ones.

Having written the above, now I see that Jeffrey said it was a 
problem "with the current syntax" in his post.

Sorry if I'm raising a point that has been covered in a more 
intelligent way already. There are just so darn many messages on 
this list . . .

As I understand it, Zope hands the data stream to PCGI who then, outside
of the Zope process trickles the data to the consumer.

Here's a brute-force way to do it, as long as the list of items was
short:

<!--#call "REQUEST.set('foo',['1',
                       '2','3','4','5'])"-->

I predict we'll have something like this called a Membership System,
say, May 18th for a first cut.

If my previous history of fibs, spinning, obfuscation, and downright
lies makes you suspicious, or if you distrust my poor prognostication,
I'd suggest that you take the user objects in UserFolder and turn them
into extended DTML Documents, or perhaps even Folders.

There are many ways to do this, as you might imagine given
that Zope is a fully programmable environment. One such way
was done by Andy Smith (cc'ed on this reply) in building an
"alumni community site" for our (Andy and my) old
department. The site is http://www.ged.org. Unfortunately,
you won't be able to see much, as it's a password protected
site for members (there are two public pages). However, on
one of the public pages, you will note that it was the
intention all along to publish the source to the site for
the Zope Community at large.

As functional as the site is already, I think Andy had some
very cool extensions in mind before opening it up to the
public. Still, he can easily ship you the GEDUserFolder that
he built to keep track of everyone's contact info (easily
extendible to all of the fields you have in mind). As a user
of the site, I can assure you that it's a breeze to use!

Perhaps, this will also be incentive enough for Andy to
polish off some of his other goodies and release them :-)

Andy's stuff above is all kept in the Zope DB :-)

Tablua, what's that? Just kidding, it's now called Z Tables
:-). For the moment, we are actively selling (without
actively promoting) Z Tables. While you get the source, it
is _not_ an Open Source product. The license does not permit
redistribution of any kind, and does not permit derivative
works, etc. It does, however, permit you to use it to
operate any kind of website, including a publicly accessible
one, etc... The price is dirt cheap for the functionality
(IMHO). The license also has a clause that specifically
permits Digital Creations to eventually release Z Tables as
Open Source(tm). Meaning, when we're ready to release it,
don't be mad that you paid for it when others get it for
free... This is important, because it is our intention that
over time, the vast majority of our stuff will be Open
Source!

So, why do we charge now? A few reasons:

1) The docs are really weak. Rather than get beat up in
   public for it, we have a license clause that forces you
   to acknowledge that the docs are weak, and that you need
   to be able to read source to really understand the full
   power.

2) Support. Everything that we put out there causes a
   certain amount of extra work. The more sophisticated the
   code, the more work. Z Tables is _hot_, so if it were out
   there in its current form, everyone would want to use it
   (trust me on this one!), so it would become a support
   burden for us. Pay us for the product, and it's worth our
   while to support you!

3) Before putting out something to the world, we really want
   to make sure it's been beat up. It may sound strange that
   we would charge people to help us turn something into a
   polished product, but it's already powerful enough to
   solve real problems, so motivated users are our best bet
   to help us achieve our goals for a more general release.

See some earlier posts from people who have recently gotten
Z Tables! For example, check out a recent
"performance-oriented" post by Theodore Patrick of
Indigo Networks!!!

Subject: [Zope] INSERT Syntax with Zope & ZPyGreSQLDA
Message-ID: <87hfrp1js9.fsf@eurythro.savigny.stp>

Hello,

I'm trying to use PostGreSQL with Zope, but I'm having
problems using the SQL INSERT method in Z methods which
require parameters.

For example, I make a Z SQL Method named 'foo'.
In it:
INSERT INTO messages
VALUES
  (<!--#sqlvar auteur type="string"-->, 
   'blahblahblah', 'now', 'f')

I write the name auteur in the 'arguments' form.

Next I create a DTML document with:
<form action="foo" method="GET">
Auteur: <input width="30" name="auteur" value=""><br>
<input type="submit" name="SUBMIT" value="Envoyer">
<form>

When submitting the form, it displays me a new page
(generated by Zope) asking me again the auteur parameter,
as if the auteur variable wasn't passed to the Z SQL method :-(

Someone posted a mail recently with an example use
of INSERT, where he put '(auteur)' after the 'INSERT INTO messages'
text: INSERT INTO messages (auteur) ...

When I try this, I get:

Error, pg.error: server fatal error. Please report to your db administrator. 

SQL used:

INSERT INTO messages (auteur)
VALUES
  ('testing again', 
   'blahblahblah', 'now', 'f')

Is there something specific to PostGreSQL ?
(Using Zope 1.10.2, PostGreSQL 6.4.2, PyGreSQL-2.2, ZPyGreSQLDA 0.02)

I looked in the Z SQL Method User's guide, but nothing is written
about adding data to a DB :-(

A good to test your SQL is using psql.

And upgrading to PyGreSQL 2.3 or later, which return proper sql messages

This is definitely wrong ;(

something like 
INSERT INTO messages (auteur,title,bookdate,any_good)
VALUES
  ('testing again',
   'blahblahblah', 'now', 'f')

might have worked. You may also mean current_date or current_time 
instead of now or now()

I didn't find any other way, either. But here's an External Method you can
use.

--- begin loop_range.py ---
LoopRangeError = 'LoopRangeError' # Name an exception class.
loop_range_limit = 100            # Maximum allowable loop index.

def loop_range(max):
    if max <= loop_range_limit:
	return range(max)
    else:
	raise LoopRangeError, max
--- end ---

Notice that it won't allow the "max" parameter to be bigger than 100. This
prevents users from generating near-infinite amounts of HTML and freezing
your server. You can edit this to any value you like, or even remove it if
you trust all your DTML authors.

Now, create an External method with the following properties:

  id:     loop_range
  title:  Loop Iteration Method
  method: loop_range
  file:   loop_range

To use this method in DTML, try the expr attribute of the #in construct:

--- begin sample DTML ---
<!--#in expr="loop_range(max=50)"-->
<P>Index: <!--#var sequence-item--></P>
<!--#/in-->
--- end ---

> Is there an easy way to do this? Is there *any* way to do it?

Yup. ;-) Zope has tons of power hiding under the hood, and a skilled Python
programmer could make it do almost anything.

One way of doing this would be using an external method:

def MyRange(iMax):
    return range(iMax)

The property bobobase_modification_time gives you the last modification
time. This is not in the docs, I gleaned it from Zope's source (it is used
in amongst other places the document edit screen). This is a good item for
the FAQ.

Message-ID: <Pine.LNX.4.04.9903132129250.14974-100000@zeus.carolina.rr.com>

Hello, everyone. I'm bustin' ass on my project for the outdoors group and
ran into a problem with the #sqlvar command.

At the top of the file, in the docstring, it says:

    For example, given the tag::

      <!--#sqlvar x type=nb optional>

    if the value of 'x' is::

      Let\'s do it

    then the text inserted is:

      'Let''s do it'

    however, if x is ommitted or an empty string, then the value
    inserted is 'null'.

Either I'm totally off base somewhere, or this is not correct. In one of
my SQL Methods I have a query, with a line:

  <!--#sqlvar address2 type=nb optional-->

And, when I submit the query while leaving address2 blank I get:

  Invalid empty string value for address2

When reading the code, beginning on line 200 there is the else case which
handles values of types other than int or float:

        else:
            v=str(v)
            if not v and t=='nb':
                raise ValueError, (
                    'Invalid empty string value for <em>%s</em>' % name)

            v=md.getitem('sql_quote__',0)(v)
            #if find(v,"\'") >= 0: v=join(split(v,"\'"),"''")
            #v="'%s'" % v

There is absolutely no check for the optional flag in this case as there
are in the cases for int and float. Is this check supposed to be handled
elsewhere in the code, and never make it here, or is this an oversight? I
can patch it to fix the problem quite easily, but if this is not the
preferred way of doing things I'd like to know (to avoid patching it every
time a new Zope comes out.)

I have two address lines, address1 and address2. I just want it to set
address2 to null if the user does not fill it out. Is that too much to
ask? :^)

As I said, if I'm blatantly overlooking something, please let me know. If
not, I'll be happy to submit a patch and/or report this in the collector.

Thanks. Hope you all are having a good weekend!

Subject: [Zope] MySQL & integer IDs
Message-ID: <199903140517.AAA01144@mail.digiweb.com>

Hello all, 
First let me start by saying I've finally cleared time to play with zope.  
Its coming along nicely but I've hit a snag.  The following snippet in a 
form:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<!--#in qryListStaff -->
<OPTION VALUE="<!--#var user_id-->"><!--#var user_name-->
<!--#/in-->
</SELECT></TD></TR>

using MySQL produces the following HTML:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<OPTION VALUE="2L">Alan Johnston
<OPTION VALUE="1L">Tom Jenkins
</SELECT></TD></TR>

Now unfortunately I believe the L is causing the insert to fail with an 
invalid integer.  I specified user_id as integer unsigned zerofill 
auto_increment.  Does anyone know why the 'L' is being return?

TIA

The L value is caused by a long integer to string conversion. You can get
rid of the L by specifying a C format string, like so:

<!--#var user_id fmt="%u"-->

Ow you're right. But this hasn't changed anything, it still
ask me for the parameters after clicking on submit :-(

In the HTML form, I replaced the action with 
'<form action="add_message/manage_test" method="get">'

where add_message is the Z SQL method. And it adds correctly the
record to my Database, but displays 'This was not a query'.
And, well, I don't think taht's the correct method to add records,
by using the test method :-))

Is there anywhere an example of product adding some records to
a database ?

What's the difference between now and current_date / current_time
I tried all of them, and they give exactly the same result 
(the good date :-)

Subject: [Zope] Zope LDAP Products available (v0.1)
Message-ID: <199903141232.XAA17000@mbuna.arbhome.com.au>

Short Version of message: ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now 
available from http://www.interlink.com.au/anthony/python/

I'm looking for opinions on the LDAP zope product I've been building.

Right now, LDAP connections work, LDAP Methods work, but there's still 
a bit more to do. Right now, the following is unimplemented:

In ZLDAPconn:
. Anything other than simple_bind(who, passwd) for connecting to the 
    LDAP server
. meaningful doc strings

In ZLDAPMethods:
. Pluggable Brains
. Result Caching
. Limits on the number of results
. Variable interpolation in the filters, and in the base DN
. modify or add queries (only search is supported right now)
. meaningful doc strings :)

Other stuff:
. UserLDAP is not finished yet (or released) - the primary issue is the
    storing of roles and domains. Right now this would have to be some
    non-standard LDAP attribute... but what should it be? It also probably
    needs modify and add added to ZLDAPMethods before being really useful.

Things I'd like comments on:
For ZLDAPconn:
    what other bind methods would you like to see?
For ZLDAPMethods:
    how should add/modify/query be distinguished? Separate methods?

I had planned to get variable interpolation working tonight, but decided I'd
rather get an early night. Probably tomorrow evening, instead. Stuff I hope to
get going in the next day or so: variable interpolation, pluggable brains.

Anyway, ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from 
http://www.interlink.com.au/anthony/python/

It requires David Leonard's ldapmodule, from 
http://www.it.uq.edu.au/personal/leonard/dc-prj/ldapmodule/

It's been tested on Linux 2.2, under Zope 1.10.2 and ZServer. Assuming the
ldapmodule works on other platforms (it's available in source, and also as
a windows .pyd) it should work elsewhere, too.

Try something like:

<form action="add_message_result" method="get">

And then create a DTMLDocument or DTMLMethod called add_message_result
like this:

<!--#var standard_html_header-->

<!--#call "add_message(REQUEST)"-->

<h2>Success!</h2>

<p>
  Your message was added successfully! Thanks!
</p>

<!--#var standard_html_footer-->

The success message will only be shown if the query succeeds, because it
is below the #call statement.

Hope this helps!

thanks guys that was exactly the problem and the above fixed it.  I

The docs seem to imply that you provide fsdir with a *directory*
ie fsdir=/web/srvs-sol/www.so.cz/ppm

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC61@peter.sths.org>

How can I configure ZAP so that all http requests go through the cgi?
Zope is the only thing running through this apache, so I don't want
everything on the site prefixed with Zope/ (or anything else, so no, I
don't just want to know how to change the prefix). This is basically
what is keeping me on ZopeHTTPServer. 

BTW, running ZopeHTTPServer multi-threaded worked well for about 15
minutes. Then suddenly certain pages wouldn't load. I stopped and
restarted the server, but the pages still wouldn't load. I also noticed
that if I stopped Netscape and hit reload, it would cause several new
ZopeHTTPServer instances to appear, and doing so again would continue to
create new instances which never seemed to dissappear. Are these locking
the items they are downloading? The behavior I saw seemed consonant with
it locking the item it was downloading, then failing to recognize the
netscape had disconnected, and thus never removed its lock. When I
restarted it single-threaded, all the pages came up without a problem. I
would really like to move to Zap, but I can't afford at this point to
have the URL of the page change. 

How can I make a Zope pcgi accessible as the root of a Zap install?
Please help.

I've imported a directory using fsimport and it worked for me. I can only
suggest (clutching at straws here) that having '.' in the fsdir attribute
might be throwing it?

Even more clutching here - did you leave the trailing slash off the fsdir
attribute?

In lib/python/StructuredText/StructuredText.py, modify the ul() and ol() methods
as follows:

Change:

  if p: p="<p>%s</p>" % strip(ctag(p))

to

  if p: p="%s" % strip(ctag(p))

I posted a more robust diff to the zope-dev list last night, which allows
replacement of the list-element format string from an ExternalMethod.

Subject: [Zope] Simulating static URLs, end-user session management
Message-ID: <36EC3A7B.53817A8D@erols.com>

Hi.  I am very new to Zope, having spent the last day
(with only about two hours of sleep) excitedly pouring through
the documentation.  I still have a lot to digest, but
there are some questions I did want to ask at this stage:

A)  Are there reasonable ways of arranging to have
    the URLs for some/many Zope generated pages appear, as
    far as the outside world is concerned, to be URLs
    for static HTML pages?  

    The issue is one of indexing by search engine robots.
    I anticipate building a site where most of the 
    content will change fairly slowly, and where there 
    would be a standard set of views of the data which 
    would be essentially static at a logical level.  I 
    really want search engines to index those static 
    views.  (There would likely also be dynamically
    generated views which shouldn't be indexed.)

    So, I think the requirement is that there should be a
    way of getting to pages with a URL like:

	http://www.mydomain.com/here/there/everywhere.html

    as opposed to

	http://www.mydomain.com/here/there/everywhere

    or

	http://www.mydomain.com/here/there?everwhere

    I supect there are a number of ways of tricking Zope
    into accepting URLs in the first form, or perhaps
    into actually generating some static pages which would
    be served up directly by the HTTP server (though
    my quick check of the archives suggests this is an
    unresolved issue). My questions are:

    1) Has anyone already done something like this?

    2) What approaches could you suggest to accomplish
       this?

    3) Is trying to arrange this likely to be a big task
       or a little task (as subjective as that question is)?


B) On another topic entirely, I am wondering about the issue
of tracking sessions of end-users.  (Hmmm... maybe I should
have done more searching in the archives -- this must be
a common issue.)  Various application servers (e.g., for
Java servlets) that I've looked at provide facilities
for maintaining "session" information (not in the sense
of a transaction as used in Zope) about end users.   Typically
this would be done by setting a cookie or by incorporating
a session ID into dynamically generated URLs.  I haven't
noticed anything about this in the Zope documentation.
I'm guessing that perhaps that is because Zope is so
powerful that implementing something like this yourself
is regarded as trivial.  But thinking about it a bit,
I'm not sure what the Zope mindset would be about how
to do this.  Zope sends requests directly to objects.
But in order to manage a session cookie (or whatnot)
you need to add a certain functionality to every (or
most HTTP) requests.  You certainly don't want to have
every object explicitly worry about this.  Is there
a hook that would allow all requests to
pass through some sort of filter that extracts/manages
session information?  Or is there some other standard
solution to this problem?


For what it's worth, I am interested in using Zope
to build my second E-commerce site.   I built the
first site by using Python to generate static pages
from a data structure, combined with lots of JavaScript
and a little Perl CGI.  It worked, but I'm sure there
is a better way.  I was leaning towards a Java servlet
plus templating package solution, until I found Zope.
I've been a Python proponent for a while, but Zope is 
threatening to make my brain explode.  Talk about 
paradigm shifts. 

C) Despite my Python and OO background,
it's not easy to absorb it all at once.  This does
make me somewhat concerned, as my business partner,
who will be a content provider, has no OO experience.
I don't want to produce a system where it will be
hopeless for her (possibly with help from another
developer) to take over if I get hit by a bus.
Thoughts...?

Robert,

I'm only going to address your last point, but it's 
something I feel strongly about.

Let's ignore the technical issues, except to mention
that only you can judge is Zope is appropriate for
your situation.  Fortunately, you have an excellent
opportunity to discover its relative strengths and 
weaknesses.

One of the important secondary issues (some would 
claim the primary) about Open Source is that it
protects your business against the "What happens if
Robert gets hit by a bus?" scenario.  Digital Creations 
is in the business of providing support to organizations 
that use its products.  Heck, in this sense it's even 
superior to key man insurance.

Furthermore, because of DC's courageous decision to 
release Zope as Open Source, not only is your company 
protected against *your* untimely demise, but it's even 
secure against the day Hadar decides to transfer all 
the company assets into hedge funds.

Best regards,

Jeff Bauer

Subject: [Zope] Help!  How do I make the JobBoard example work?
Message-ID: <EF3E7C5CCD67D211A43C006008AE49B8181FF7@JUNG>

Hi All,

As an exercise, I'm trying to get the JobBoard example code given in
http://www.zope.org/Documentation/Reference/ObjectPublishingIntro to work in
Zope (as opposed to Bobo/ZPublisher), and am having some difficulty.

Copying the PeeWee's playhouse example in
http://www.zope.org/Documentation/Reference/ExternalMethods, I placed all
the JobBoard files in zope/lib/python/shared/JobBoard, made an empty
__init__.py file, fixed up the dtml_loc variable, and put a
JobBoard_utils.py file into zope/extensions, which reads as follows:

  "utility to add JobBoard objects to folders"

  def addJobBoard(self,id):
      "Add a playhouse to the current folder"
      if not hasattr(self,id):
          setattr(self,id,JobBoard("Python Jobs"))
          return "JobBoard added with id %s" % id
      else:
          return "id %s already in use" % id

Using Zope's management GUI, I successfully added the addJobBoard function
as an external method, and have successfully called it to create a JobBoard
object called testJobBoard.

However, when I try to view the testJobBoard object, I get an error message
that reads "Sorry, the requested document does not exist."

The addJobBoard function was added as an external method to the root folder,
so my understanding is that the testJobBoard object should also be
accessible from within the root folder (that is that its URL is
"localhost:9673/testJobBoard").

What am I doing wrong here?

Also, what is the proper way to debug this sort of problem?  The output of
the zope process merely mentions a GET request for the given URL, and the
404 response code -- no further detail is given.

Thanks in advance for the help!

-Justin

In looking through my Apache configuration files, I tried to piece
together what changes I made. Here's what I think you need to do.

In httpd.conf, make sure you have these lines (I put them at the end):

Alias / /cgi-bin/Zope.cgi

# Zope configuration maps /Zope/ to the Zope.cgi CGI script
RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

NOTE: In the RewriteRule directive above, the [e=...] stuff should go
directly after the ...Zope.cgi/$1 section, with a space separating them,
e.g. ...Zope.cgi/$1 [e=HTTP...]

You will need to munge the path in the RewriteRule directive, where it
says /home/httpd to be wherever your document root is.

I did this a while back, and have since switched from Apache to ZServer to
test it out, so I haven't used it lately. However, this should work, as I
never changed the config files after I stopped using Apache.

Let me know if you have problems; I'll do what I can to help.

Thanks

You say "one shouldn't have to use <!--#var "_['foo']"--> instead of
<!--#var foo-->."
However, i find it useful to write:

<!--#if "_['foo'] and _['bar']"-->
<!-- blah -->
<!--#/if-->

instead of:

<!--#if foo--><!--#if bar-->
<!-- blah -->
<!--#/if--><!--#/if-->

Hope that helps...

<!--#var "img.name"--> is the best way to go. It'll insert a IMG tag with
an absolute URL, and if it knows the image width and height, these will be
included in the image tag. Make sure you use the quotes! img.name means:
the attribute 'name' of the object called 'img'.

You can specify the image width and height by hand in the images' property
screen, but if you uploaded a PNG or GIF image, Zope will deduce the width
and height from the image itself. The next Zope release will also support
JPEG image size detection.

Yes, that's what I want. 

Maybe what I'm trying to do is against object-oriented concept? I can
see that images should be kept with the DTML page that calls them. I
just need images to be accessible by a group (role) of "image managers",
but the code that holds it to together should be accessible to an Admin
role only.

There is little reason to avoid naming your objects with the extension
built into the ID, like everywhere.html. You can then simply refer to the
object using that ID, which to a not so smart indexing bot will look like
an HTML file (but it should *really* look at the MIME-type...). The only
problem would be referencing the object, as you have to take precautions to
make sure Python doesn't try to reference the attribute named 'html' on the
object 'everywhere'.

So, as long as you name your DTML Documents that are to be indexed with the
.html extension, everything should go fine.

No, Zope has no Session tracking facilities at this moment. DC is however
working on this. At the moment you will find a 'Session' object in your
Zope distribution, but this is a different concept altogether, and will be
renamed to 'Version' when client session objects appear.

DC can be hired to help out... and as Zope is now Open Source, a growing
number of people can help out.

How about

<!-- blah -->
<!--#/if-->

or 

<!--#if "_.getitem('foo', 1) and _.getitem('bar', 1)"-->
<!-- blah -->
<!--#/if-->

So we can confuse each other even more =).

Yep, you got use there.... calling the Image object doesn't generate extra
information like border=0. DC is working on a solution to that, at least, I
think they said so.

For now you will have to write out the IMG tag yourself:

<IMG SRC="<!--#var BASE1-->/img/name" width="<!--#var "img.name.width"-->"
height="<!--#var "img.name.height"-->" border=0>

I assumed that the img Folder object is a direct subobject of the Zope root
object.

I was afraid it would be the case.... I thought I could use Property
somehow (adding text Property named Border with the value 0) but then I
realized that I can't interfere with it, since the rendering takes place
INSIDE while properties are OUTSIDE.

Looks terrible :-) I think I rather use <img src=img/name border=0> for
the time being.

Also, is there any problem with the instances failing to work with a newer

okay next qustion: I have a image under a folder called "images".
<!--#var "images.somefilename"--> should work - except that the image filename
contains the "." character (eg: "foo.gif") and this gets confused with the dot
notation of the object (it tries to find images/foo/gif and chokes with a

So how do I get round this one?

Subject: [Zope] File upload product anywhere?
Message-ID: <v04104401b312cbb2cbde@[128.240.198.13]>

Hi all,
Has anyone written a file upload 'product' that they'd like to share?

My own requirements are that;
the files should (optionally) go to a file system,
I need to be able to change the interface for the system,
the users should be authenticated from an external database,
the files (if held in a file system) should retain their associations 
with folders (for permissions and access),
and I'd like it in blueberry please.

What I'm basically after is the best of both worlds - Zope 
permissions/acquisition etc. with the 'safety net' of a file system 
for large files (and possible batch uploading).

My problem (or one of them) is that there's no way that I'm up to 
speed enough in Zope/Python to start on this...I have a system doing 
the file upload working well in PHP3, but that (obviously) doesn't 
have the permissions/acquisition power of Zope. I guess I could do 
redirects to my PHP3 scripts from within Zope however, but it's 
hardly (ahem) 'elegant'.

any thoughts gratefully accepted.

The find management screen does give helpful hints. If you want to
implement this kind of searching, you'll have to use the same techniques.
These are however largely undocumented.

The file lib/python/OFS/findResult.dtml should give you a lot of hints on
how to implement a search command. It comes down to calling PrincipiaFind
on a Folder with the right arguments:

obj, obj_ids, obj_metatypes, obj_searchterm, obj_expr, obj_mtime,
obj_mspec, obj_permission, obj_roles, search_sub, REQUEST, result, pre

where

* obj -- base folder to start at

* obj_ids -- (optional) list of object ID's to search

* obj_metatypes -- (optional) list of meta types to search for (if the
string 'all' is in this list, all objects, whatever their meta type will be
included in the results).

* obj_searchterm -- (optional) literal text to search for in the *source*
of DTML Documents and DTML Methods.

* obj_expr -- (optional) DTML expression (as would be used in the expr
attribute of for example the var tag). If this expression returns true
within the context of an object, the object is included in the search
results. You could use this for testing on certain properties, like 'foo=bar'.

* obj_mtime -- (optional) DateTime object or string that can be converted
to a DateTime object, specifying a modification time to compare objects
against. Will on default return objects that have been modified since
obj_mtime.

* obj_mspec -- (optional) When used with obj_mspec, and set to '<',
PrincipiaFind will only return objects which have been last modified before
the date and time specified by obj_mtime.

* obj_permission -- (optional) To be used together with obj_roles. Check if
the roles specified by obj_roles have the obj_permission permission. Only
these objects are included in the results.

* obj_roles -- (optional) List of roles to check for obj_permission access.
See obj_permission.

* search_sub -- (optional) if true, search subobjects recursively.

* REQUEST -- (optional) REQUEST object, used to make sure that
AUTHENTICATED_USER is available for obj_expr expressions.

* result -- a list of objects to be included in the returned results. Used
by the PrincipiaFind method when recursively searching subobjects.
Generally of no use to us humble DTML programmers.

* pre -- prefix the IDs in the returned result list with pre and a slash.
So, when called with pre='foo', and bar is the only object found,
PrincipiaFind will return the list of tuples: [('foo/bar', foo)]. This
argument is used when recursively searching subobjects, where pre is the
relative URL of the object searched.  Generally of no use to us humble DTML
programmers.

The method returns a list of tuples, where the first element of every tuple
is the relative URL of the object found (relative to the starting point),
and the second element is the object itself.

Object name can be different from filename. Thus you name your foo.gif
file just Foo, and that's it.

Zope's object database uses Python's pickle facility, so in general
instances only store their own data, and use whatever version of the class
is available. Classes are not stored in the database. This means that when
you change your class, your instances will be updated.

>Also, is there any problem with the instances failing to work with a newer
>product version?

Yes. And this is not a Zope-specific issue, or even a Python-specific issue.

Anytime you have long-lived instances and change the class, you may run
into problems. Python comes with a couple hooks to help you out. You should
look into __getstate__ and __setstate__ which are documented in the Python
pickle documentation.

Probably the most common type of problem occurs when your new class
definition assumes a new attribute which the old instances don't have. An
easy way to solve this is to provide a class attribute which gives a
reasonable default for this attribute.

For example:

class MyClassV1:
  'Original class'

  def __init__(self):
    self.color='red'


class MyClassV2:
  'Updated class'

  def __init__(self):
    self.color='red'
    self.texture='bumpy'

  def describe(self):
    return 'I am %s and %s' % (self.color, self.texture)

Notice that instances created with MyClassV1 will not have a 'texture'
attribute, so that when the class is updated, old instances will break when
you call the new 'describe' method. A simple fix is to provide a default
class attribute. For example:

class MyClassV2:
  'Backward compatible updated class'
  texture='nondescript'
  ...

Now old instances won't break in the 'describe' method.

Another approach is to test for the attribute and update the instance when
you're going to use it. For example:

  def describe(self):
    if self.texture=='nondescript':
      self.get_texture()
    ...

If 'describe' is the only place where you use 'texture' then you wouldn't
even need to provide a class attribute, and could simply test for the
absence of the attribute.

Finally you might include version numbers in your instances and test for
these, but this seems like overkill. I would suggest sticking to default
class attribute solution for most cases.

Hope this helps, and good luck.

In general, when you have trouble spelling an object's name in a variable
expression because its name is not a legal Python name (e.g.
'sequence-item' or 'foo.gif') then you should use _[] or _.getitem

However in your case you can simply get the sub-object with a plain old
getattr:

<!--#var "_.getattr(images,'foo.gif')"-->

Another possibility is to use the with tag:

<!--#with images-->
<!--#var foo.gif-->
<!--#/with-->

Since these are so ugly, you might consider the simpler manual method of
generating the img tag:

<img src="images/foo.gif">

or else you might consider *not* having a images directory, and keeping
your images in the Folders where they're used. Then you can refer to the
images directly:

<!--#var foo.gif-->

And because of acquisition, foo.gif is accessible to all sub-Folders of the
Folder it is located in, in the same way.

Well, since that's a symlink anyway, I tried to suck directly from

I tried both.

I'm sure I must be crazy. I summarize what I did:
1. downloaded fsimport.py
2. mkdir /usr/local/zope/Extensions
3. chown nobody:www Extensions
4. chmod /usr/local/zope/Extensions to be rwxr-xr-x
4. copied fsimport.py to /usr/local/zope/Extensions
5. chown nobody:www fsimport.py
6. chmod fsimport.py to be rw-r--r--
7. created External method fsimport inside of ppm
8. put "fsimport" into all 4 fields (Id, Title, Function name, Python
module name)
9. http://www.sol.cz/Zope/ppm/fsimport?fsdir=/home/pes/public_html
10. error "TypeError: read-only buffer, class"

I must have missed something.

Perhaps I'm failing to understand something.
Looking at pages on zope.org and some obviously dynamic pages
on other sites, they all return a MIME-type of "text/html".   Which I
think means that a smart indexing bot should *not* simply look at the 
MIME-type.

As I understand it, most search engine robots try to exclude dynamic
content because of the justifiable fear that once they start exploring
a web of dynamic content they could get lost in an infinite or
near-infinite search space.  I've read that as a result of this, 
search engine robots do things like refuse to index any URL with 
"cgi-bin" in the path, or which do not end in an approved recognized 
file extension.

Do you have a different perception of search engine robot policies/strategies?

Are there any projections available re the timing of this?  I'm wondering

FWIW, in my mind an ideal client session scheme would allow multiple strategies.
In most cases using cookies works out for the best, but I would like to be
able to accommodate anti-cookie zealots as necessary.  On the other hand,
I don't want to clutter URLs with session-id's if I don't need to.  (I suppose
having authenticated users is yet another strategy, and one that Zope currently
seems oriented towards.  Fine if users really want or need to get into your
site or need to perform authorized operations, but not so good if you're trying 
to entice them in.)

Message-ID: <36ED786F.60F36D39@erols.com>

While I expect to eventually be working under Unix
(once I can convince my hosting provider to install Zope),
at present I'm trying to use Zope under Windows 98.

The problem is: it's not working.

I'm using the Zope HTTP server, and I can contact the
management system just fine, a prowl around looking
at everything.  But if I try to add an object (whether
it be a DTML Document, a Folder, or an "Item" from
the sample_product package (which I installed), what
happens is:

	I am allowed to fill out the form where
	you enter object creation fields (ID, title, etc.),
	but when I send that form the HTTP server never
	returns.

Any clues as to how to fix this, or debug it, or get any
idea as to what is happening?

Subject: [Zope] Zope modifies HTML order of tags?
Message-ID: <36ED7A29.89A174FC@sol.cz>

It seems to me that Zope is rendering my HTML tag attributs in different
order than in the source. For instance I put 
<table width="100%" cellspacing="2" cellpadding="2">
into property named tabstart.
Looking into source produced by Zope, I found
<table CELLSPACING=2 CELLPADDING=2 WIDTH="100%" >
Why is Zope doing this? Maybe there's good reason, but I'd like to know,
because too smart software is sometimes more burden than a help.

Also some attributes are omitted in the rendering process. Property
"width=106 height=106 border=0 align=right hspace=10 vspace=0" ended up
without vspace statement.

Subject: [Zope] DTML indirection question again
Message-ID: <36ED95B4.4EE4B7DD@findlaw.com>

OK, here's the situation.

I have a "login" page that I want to list the contents of different
directories depending on the value of the AUTHENTICATED_USER

Each user has a folder under the folder 'user'.

I would like to be able to do (simplified):

<!--#with expr="_.getitem('user'.AUTHENICATED_USER,0)"-->
<!--#in "objectValues()"-->
<!--#with sequence-item-->
<a target="_view" href="user/<!--#var id-->"><!--#var title--></a><br>
<!--#/with-->
<!--#/in-->
<!--#/with-->

However, I get a TypeError on the #with line (and even if I put in the
AUTHENTICATED_USER.id instead of just AUTHENTICATED_USER).

What am I doing wrong here? I've tried a lot of different combinations
of #with and _.getitem and such..

 THANKS

Victor,

I think your problem lies elsewhere.  The client does not
have to bind a local address before calling connect.  The
connect() function automatically assigns an unused port
to the socket.

You will probably find the problem is much more obvious
than a low-level socket bug.  Check your Zope.cgi paths,
permissions, and Apache configuration.

Good luck.

FWIW, after messing around for several hours trying to diagnose
this, the problem mysteriously went away.

(I uninstalled another version of Python and its extensions,
reinstalled them, ran Zope inside Pdb -- and things started
working.  Got out of Pdb, restarted, and things continued
to work.  No clue as to  why things were consistently hanging
before.)

Subject: [Zope] setting variable
Message-ID: <199903160352.WAA04182@mail.digiweb.com>

Hello folks,
I'm stuck on a problem which I hope some one could help me with.  I 
have a database entry form where the user will enter in information for 
two related tables.  When she submits the form, I want to first post one 
tables information, then call another sql method to get the id generated 
for that post, then take that value and add it to the REQUEST object 
and pass it to the second sql insert for inserting to the second table 
(along with some other parts of the REQUEST object from the form).  

I'm planning on using MySQL that has a special select:
select LAST_INSERT_ID()
to return the last auto-generated id value to get the id.

I know you can add a variable to the REQUEST object via
<!--#call "REQUEST.set('varname', value)"-->
but how to I get the value from the sql method?  The only way I know 
now is via #var tags but you can't nest the DTML.

I hope this makes sense...

This is something Zope can´t influence, it´s part of the way your browser
works.

Could you supply us with some DTML examples of this behaviour? It´s not
something I´ve seen before. Is there any chance your HTML editor is doing this?

I'm wondering; is there a reason why 'range' isn't accessible from DTML
in the '_' namespace? Is the reason as you indicated in your external

DTML?

Just curious,

The reason if of course merory flooding attacks. A range that asks for a
list of 3 billion items is a wee bit unpolite to the machine.

A way of checking would be:

RANGELIMIT = 1000

def SafeRange(iFirst, *args):
    if not len(args):
        iStart, iEnd, iStep = 0, iFirst, 1
    elif len(args) == 1:
        iStart, iEnd, iStep = iFirst, args[0], 1
    elif len(args) == 2:
        iStart, iEnd, iStep = iFirst, args[0], args[1]
    else:
        raise AttributeError, 'SafeRange() requires 1-3 int arguments'
    
    if iStep == 0: raise ValueError, 'zero step for SafeRange()'
    
    iLen = int((iEnd - iStart) / iStep)
    if iLen < 0: iLen = 0
    
    if iLen >= RANGELIMIT: raise ValueError, 'SafeRange() too large'
    
    return range(iStart, iEnd, iStep)

Maybe this should be part of the _ object. Can someone turn this into a
patch and supply this to DC? I´m a bit short of time right now.

I really do hope this comes off, so let's make a go of this eh guys 8^)

Ok, two questions

1. What happened to the Zope web site, it seems to have gone down 
yesterday and still is not operating ?

2. I have downloaded ungziped and untared (Zope-1.10.2-linux2-x86.tgz), 
but the install instructions do not seem complete.  I retrieved the 
INSTALL.TXT file from the doc directory and started to follow them, but 
their doesn't seem to be any 'access' file in this distribution.  What's 
more some of the command line options come up as invalid, like -c,which 
the install program quit on saying it was a invalid option.  The -c 
option doesn't even show up in the --help for the installer.


I was hoping there would be some additional install info on the web site, 
but that's not working.

Try:

select LAST_INSERT_ID() as fred

then grab <!--#var fred-->

If this works then I know what the problem is!  :^)

If you use the database's command line tool and run this SQL statement I
bet it returns a single value (i.e., it doesn't return a table).  The DA
wants to munge and chew on rows in tables.  If think that if you use the
select LAST_INSERT_ID() as fred you'll get a one-row, one-column table
-- this is what Zope wants.

| 1. What happened to the Zope web site, it seems to have gone down 
| yesterday and still is not operating ?

It works from where I'm at. You may want to try
traceroute www.zope.org
(or tracert www.zope.org from Windows)
to see where things are getting hung up.

| 
| 2. I have downloaded ungziped and untared (Zope-1.10.2-linux2-x86.tgz), 
| but the install instructions do not seem complete.  I retrieved the 
| INSTALL.TXT file from the doc directory and started to follow them, but 
| their doesn't seem to be any 'access' file in this distribution.  What's 
| more some of the command line options come up as invalid, like -c,which 
| the install program quit on saying it was a invalid option.  The -c 
| option doesn't even show up in the --help for the installer.

The access file just needs one line of the format "username:password"
and should be in your zope install directory. Since I was using PCGI
with Zope, all I did was just untar it, make it and then copy Zope.cgi
into my web area...

Try: select LAST_INSERT_ID()+0 to cast it to an int...

Also, check your declaration for LAST_INSERT_ID().. if the above doesn't
work you'll need to either try the patch for ZMySQLDA that was posted a
week or so ago, or do something like: SELECT CONCAT(LAST_INSERT_ID()) to
cast it to a string and then use a nifty Python fn. to convert it to an
integer number. 

It seems the MySQL driver has problems with some datatypes.  There was a
patch posted befure.. I'm curious to know if it'll fix this problem...

Hi!

I'm not using zope, but I'm using ZPublisher and ZServer. I'm coding a
very simple counter module (with PIL). How could I set the mime header
to image/gif and return an image?

This is in the Zope FAQ, actually, at http://zdp.zope.org/FAQ/external.
At least I think I'd apply to ZPublisher as well?

How do I return an image from an External Method?

Example (for a png image):

    def foo(self, RESPONSE):
        # set the header
        RESPONSE['content-type'] = 'image/png'
        # return the actual image data
        return mkimage()

Another way to set the header information is:

    RESPONSE.setHeader('content-type','image/png')

Martijn

You are right. I wanted to check the frame, which I can't do easily
under Netscape, so I pushed File/Edit Frame, and apparently Netscape
Composer did it, because when I do "Save frame as...", it looks O.K.

Having discovered this, there is no chance I would ever use Composer. I
would be happy to have Zope work as closely as possible with
Dreamweaver, though.

I've been using this.... (Zope example but should work with ZServer)

It was fully expecting to have to mess about with headers to get browsers to
recognise the gif, but broswers seem to know a gif when they get one!

This example returns gifs in a browser when you do ....

http://mysite/renderGif

or even

<IMG src="renderGif">

(I'm fully prepared to admit there may be better ways of doing it) ;)_

Cheers,

Andy.

    def renderGif(self, size=500, counter=1):
        """Draw a pie chart"""
        im = PIL.Image.new('RGB', (size,size))

        # Do GIF manipulation stuff here!

        outFile = cStringIO.StringIO()
        im.save(outFile, 'GIF')

        outFile.seek(0)
        outString = outFile.read()

Why not use:

select 'id_field_name' from 'table' where 'id_field_name' IS NULL

id_field_name beeing the field with AUTO_INCREMENT set

When using Zope to publish XML documents (using DTML Document objects) I
often write:

  <!--#call expr="REQUEST.setHeader('Content-Type', 'text/xml')-->

Some part of Zope tries to guess the Content-Type otherwise. A lot of this
code is directly shared between Zope and Z Publisher, so you might see
similar behavior.

Eric

Subject: [Zope] Help - need a brainless guide to getting zope running
Message-ID: <36EEBBF1.B7B05990@netscape.com>

Ok, I consider myself pretty technical, but not a UNIX master, and I've
used NT enough to know about services, etc.  But I cannot for the life
of me figure out how to get zope running as a service without manually
starting it from start.bat.


Could someone please post somewhere a "zope for dummies" description of
getting zope running as a service on NT.

Here's what I do:

I downloaded zope 1.10.2
I unzipped and ran the installer.
It works fine to the point where it wants me to choose between running
zope alone or as a service.
I've tried it "both ways" and although I can get zope running fine by
manually starting it from start.bat, and
I make the zope service start automatically, it will not work as a
service!

I dont have any other web server on this machine and dont really care
which server I use. I had assumed that ZopeHTTPServer  would run as the
service, but it doesnt work...

Is there just a minimal way to get zope going on it's own?

I know the ip address etc. of my system, but that doesnt seem to be the
issue.

I wouldnt even mind if in the install you had an option for "install
default web server" so that zope can piggy back on it.

Does it have something to do with setting permissions to the var
directory?

All I'm basically looking for is sort of a recipe style instruction on
how to get it up and running. (With no handwaving like "now configure
your system to run the zope.exe".  Assume I'm a total idiot...

Which I'm not, but I'm still having problems.

No, I don't think that can work. You need another webserver, like Apache
(which you can download from www.apache.org, though of course it has its
own configuration hassles).
 
> Is there just a minimal way to get zope going on it's own?

Hm..Perhaps ZServer, but that's still not stable. Can it run as a
service in NT?
 
Otherwise I'd recommend Apache; it can do plenty, though there is a
learning curve there.

Here's what I did:

I downloaded zope 1.10.2
I unzipped and ran the installer.
I chose to run zope alone
I created a shortcut to start.bat in C:\WINNT\Profiles\All Users\Start
Menu\Programs\Startup


This will start Zope every time you reboot. Note that it will not get
rid of the annoying MSDOS command prompt window.

I hope this helps

I posted a message last week about running ZServer as a service.  You can
find the message at
http://www.zope.org/pipermail/zope/1999-March/005030.html

I built my Zope from source, so I don't know if this works the same as the
self-installer version, but it should be pretty close.

1. Install Zope 1.10.2, choosing to run standalone.
2. Untar the ZServer distribution in the root Zope directory.
3. Test that it works by running start.py in the ZServer directory.
4. Follow the directions in the message linked-to above.

OK to follow up,  if you use call mysql using the form

you get back the correct value in 'last_id'

now I'm still having problems with getting that value into the REQUEST

Umm that should read
select CONCAT(LAST_INSERT_ID()) as last_id

Well, try something like:

<!--#in lastInsert-->
	<li>The id last inserted is <!--#var new_id-->
<!--#/in-->

where lastInsert is your SQL method

Note this is untested code, so caveat emptor :)

Hi:

Are the #sqltags documented somewhere? I couldn't find them in the DTML
reference manual, etc.

I found some examples of their use, but nothing definative.

I have no problems reading the source and documenting what I find, I just
don't want to be re-inventing the wheel.

Specifically I'd like to know about #sqlgroup and friends.

Did you notice the "Z SQL Methods User's Guide":

I think that this covers what you want to know.

Do you really need this? You can put more than one sql commands in a sql
method, you just have to put a <!--#var sql_delimiter --> between them.
You can insert in the two tables with just one method. The
last_insert_id() should be in the values field of the second insert.
Take a look at the code genereated by the sql wizard in the contrib
page.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <36EEE8E7.11F8DBC@erols.com>

Right now my biggest obstacle to setting up a Zope-powered
site could be finding a hosting provider I have confidence
in who is willing to run Zope.  When I asked my first-choice
provider about running Zope, they replied:

> Though it's true that we can install programs that need root
> instlall, it only so when the program is low CPU/mem use and
> non-intrusive. Zope is neither, so to run it you would need to get
> your own dedicated server through us.

A dedicated server is not a viable option for this site at
this point in time.  So, a few questions:

1)  Are the provider's fears justified?  What sort of
    memory footprint, CPU requirements (for a site that
    should have fairly low traffic at first), and other
    impact are Zope likely to have on a hosting provider?

2)  Would anyone care to let me know what their experience
    has been with the two hosting providers (NexusWeb and
    CodeIt Computing) listed as known to host Zope-based
    sites?  (I've been sufficiently badly burned in the past
    by bad hosting providers that I cannot justify signing
    up for a provider without positive recommendations or
    multiple alternatives for backup.)

Hey Paulo, thanks for that tip.  I didn't know about #var sql_delimiter 
and the ability to put more than one sql commands in a sql method.  I 
had wondered about it but the #var sql_delimiter was the key.  With this 
information, no I don't need to insert into the REQUEST object.  But I'm 
still curious <g>.

Unfortunately, putting last_insert_id() directly into the values of the 
second insert did not work.  It works from mysql command line.

<!--#var sql_delimiter -->
INSERT INTO entry_tbl 
	(master_id,submitted_by,staff_id,version,comment)
	VALUES (LAST_INSERT_ID(),
		<!--#sqlvar entry_tbl.submitted_by type=int -->,
		<!--#sqlvar master_tbl.entered_by type=int -->,
		<!--#sqlvar entry_tbl.version type=string optional-->,
		<!--#sqlvar master_tbl.comment type=string optional-->)

It surprised me that it didn't work as I thought it would get sent enmass 
to mysql for processing so I had thought that the DA wouldn't interfer 
with it.

Subject: [Zope] newbie -  permissions on FAQ object
Message-ID: <199903170144.SAA26992@stout.atd.ucar.edu>

I'm trying to configure a ZOPE FAQ object on starship.python.net .

This is Zope v10.10.2 with ZServer 1.0b2 .

I'm baffled by the permissions scheme.  I've created a FAQ under my
ZOPE home:
http://starship.python.net:9673/crew/vanandel

I'd like selected users to add FAQ entries, but only certain trusted 
users to be able to create categories.

Unfortunately, anyone can add a new category, which is not what I want.
The Security Screen for vanandel/NumPy only enables 'view' for 
anonymous, but still an 'anonymous' user can enter the 'Add a category' 
screen, without being challenged.
There are specific permissions shown for various "add-ins" 
like TinyTables on the Security screen,
but not for the FAQ module.  (I'd expect to see permissions for 
FAQAddCategory.)

Also, when I first create a 'FAQ', I can't view it until I create
a 'isCategory' property.  This seems like a bug, since 'isFAQ' is 
already created for me.

A minor question.  I'd obviously like to test ZOPE with various users,
to see what ZOPE allows them to do.  ZOPE uses cookies to give someone 
permission, after they've supplied a password.
Under Unix, I can manually remove a cookie by editing ~/.netscape/cookies.  How do I do this under NT?  Are Netscape cookies in the registry (I hope not!).

Thanks much for your help.

Excellent.

We here at DC (well, I'm out of the office this week, but I'm there
virtualy) have been kicking around an LDAP authentication mechanism,
probably a folderoid, to go against LDAP.  In fact, this was supposed to
be one of my projects when I get back next week.  From the details below
it looks like you have thought this out well, I didn't even consider
making an API of methods like XSQL methods, good idea!

Under the catagory 'result caching' you might want to consider making some
kind of Connection Manager in your LDAP Connection.  A model I've been
kicking around is a CM class that manages Connections and uses a simple 
caching algoritm.  Wrapping all of the API in a class will also help yu 
when you want to break out the LDAP stuff and stick it in shared.  In
this way, it becomes a sort of 'Device Driver' (to use Ken's
terminology) for the entire Zope system.  We're going to be doing this
with the IMAP functionality that NotMail uses.  I'm assuming what
you call an LDAP connection is like a Database Adapter is to ZSQL methods.
Maybe you might want to consider calling these LDAP Adapters.

The etcUserFolder product has a settable property to change the 'default

Don't hurt yourself.  It looks like you got this down pretty good, I'll
proablby be looking into incorporating much of this if not all into Zope,
want to be in charge of zope LDAP?  We can give you an area on the site.

Message-ID: <Pine.LNX.4.05.9903170107540.673-100000@web.spyderlab.com>

Hey zope freaks:

Okay, I am driving myself crazy, maybe I am just doing something silly
(hopefully).

I am trying to write this recursive SQL result DTML (basically a tree):

<!--#in listCategories-->
  <p>Category <!--#var nm-->
  <blockquote>
  <!--#var recurseCategories-->
  </blockquote>
<!--#/in-->

I have a variable pwd that I want to pass along to recurseCategories..

I tried something like <!--#var recurseCategories(pwd=catID)--> (and in
quotes)

pwd is used in listCategories to get a list of categories in that 'path'

A couple questions:

1. Should I be using a DTML method or a DTML document for something like
this?

2. As I recurse will I lose access to documents in my current folder? I
got a traceback to seemed to indicate that once I was into a certain
depth I couldn't access listCategories.

3. Is there a more Zope-happy way to do this?

Probly I misunderstod your problem.

Anyways I want to say that my suggestion does just what 'select
last_insert_id()' does. namely return the number created in an
auto_increment field during your last insert

My profound apologies.  "select <field_name> from <table_name>  
where <field_name> IS NULL"  does indeed return the same value as 
last_insert_id().  My apologies again.

Hi All,

I'm just uploaded a new Product to the contrib area.

It is a poll product based on Amos's example. It uses PIL to draw
piecharts of the poll results.

I was originally going to include a precompiled PIL with the product, but
the
product swelled to 500k as a result, so instead I've left pointers to where
to get PIL in the product documentation.

I'll send a hypertext screenshot immediately after this message so that
people can decide whether or not they want to go to the effort of
downloading and installing PIL.

Pls note that there are some problems I'm having with getting the GIFs to
update appropriately, so after banging my head against a wall for a while
[in true opensource tradition ;) ] I've decided to throw it open to the
floor to see if anyone can find a workaround.

I've also uploaded a 'fixed' version of the Guestbook example product, which
broke going from Zope1.9 -> Zope1.10.

Enjoy!

Andy.

Hmm... the screenshot didn't seem to 'travel' too well,

Guess you'll just have to install PIL to see it.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <000701be709e$ea4cd4c0$642fe18d@jharris.coe.memphis.edu>

I contacted NexusWeb yesterday and they said they would provide a setup for
Zope, but no support.  They were not specific as to the setup.  They did
mention they supported Python.  I was going to write them back to see if
they ran Zserver, or just provided the links to Apache.  They did have msql
and mysql.  The minimum plan to support Zope was the 50MB/$20 a month plan.
The other site was out of my price range ($50/mo).

I just started studying Zope yesterday to use for a project I was planning
to use Visual Basic/ADO/ASP for.  I'm testing on a Win95 machine, but plan
to move testing to a Linux box.

I decided before signing up with a hosting server to wait for Zope 2, which
I've seen a couple of references to.  What's the deal on that?  One place
promised a better integrated web server.  If Zope moves more torward being a
totally self contained server, then I don't want to mess with Apache or IIS.

Subject: [Zope] Newbie questions
Message-ID: <D133051DBC4AD111B90800A0C9694983A61695@natasha.auslabs.lucent.com>

Hi Zopesters,

I'm trying out Zope for the purpose of getting a book catalogue on the web.
So far, I'm extremely impressed with it! Of course, I have some questions.
(For the record, I am running Zope 1.10.2 with Apache 1.3.something on a
MkLinux DR3 box, administered with IE4 on NT).

1. When you edit a DTML document using the Zope management interface and hit
the update button, Zope goes away and tries to parse it to ensure that it's
consistent DTML. If this fails, you are left with no option but the
browser's back button, which, under IE4 anyway, seems to discard the changes
you made to the document. Is there a fix or workaround (besides ctrl-A
ctrl-C before clicking the update button) for this? Us newbies write lots of
bad DTML :)

2. When a folder acquires an index_html document from further up in the
heirarchy, the <!--#var title--> tag refers to the title of the index_html
document, rather than the folder being displayed. How do you write the
index_html document to display the title of the acquired object, rather than
the index_html document itself? (Hope this is clear)

3. Finally, I need some advice about how best to lay out the website.
Basically I'm trying to build a site containing a book catalogue. Here's
what I've got so far:

+ Root
	+ Titles [folder]
		- index_html
		+ OriginSpecies [folder, title: "Origin of the Species",
desc: "blah",
				author: "CharlesDarwin", year: 1854]
			- cover [image]
		+ DiamondAge [folder, title: "The Diamond Age", desc:
"blab",
				author: "NealStephenson", year: 1995]
			- cover [image]
		...
	+ Authors [folder]
		- index_html
		+ CharlesDarwin [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]
		+ NealStephenson [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]

Hope the notation is clear enough. What I want to do is "link" the titles to
their authors and vice versa. So the index_html document for Authors would
display the author, their picture, bio, and a list of titles by them. A
similar arrangement would apply for Titles.

The author property of the title (*) links the title to author, but what's
the best way to link backwards? Similarly, what's the best way to display
the author's information for a title?

All advice appreciated! Thanks.

(*) assuming only one author for now

Subject: [Zope] Newbie install help needed !!!!!
Message-ID: <199903172113.QAA02057@mail.howard.k12.md.us>

Thus far my attempts to install the Zope binary release on a Linux 
machine have been for nothing.  The Install documentation and the Install 
program contradict each other at almost every turn.

The docs say use ./install -u <userid>

but the -u switch is gives a error message, saying it is a invalid switch 
and not supported at all. The install --help, says nothing about a -u 
switch.

The docs say you can specify the cgi directory, with the -c switch, but 
the install program says that is a unsupported feature.

The -s switch in the docs says this is to provide the superuser login and 
password to the install routine, yet the install program say this is used 
to strip tables (perhaps parsing the access file), none of the docs say 
anything more.

I have tried numerous variations, all to no avail.  Perhaps the ZDP 
should have started at the beginning, with usable install instructions, 
instead of with a FAQ.

I must say that the screen shots in the PDF file and those docs are quite 
nice, but thats about it.  Reading the PDF docs, just makes me want to 
get in and try Zope even more.

Is there anyone that could help or give me some pointers ?

Subject: [Zope] multiple trees
Message-ID: <199903180035.QAA28795@christopherrobin.kolo.net>

There seems to be a problem with DTML documents which 
uses more than one <!--#tree--> .. <!--/#tree--> sections.  I'm
seeing a python error when attempting to expand any node of 
the second tree.  I'm going to try and fix this on my own as
a way to familiarize myself with Zope internals but I thought
others on this list might want to be aware of the problem and/or
provide information about their own experience with multiple
trees.

It's on the list. I was originally going to write a simple LDAP auth
object, then thought about it a bit more and realised a generic interface
into LDAP would be more useful, then I can bolt the auth on top.

The way I figure it, I'll support this first. If/when someone needs 
something else, I'll look at supporting that.

Hm. The LDAP connection already is a class. It's as much a device driver
as the current Database Adaptors.

Good point. Next version, they'll be called that. (I figure I'm allowed
to make changes like this between versions 0.1 and 0.2 :)

That and maybe allowing a mapping for any organizationalRole that 
the users have. More useful for the "lecturer", "student" type
roles.

I've got variable interpolation _mostly_ working. For some reason, though,
it doesn't pick up all the namespaces - I'm probably just not using 
the document templates right. I'm going to add DTML interp. to both the
filters and to the baseDN.

Depends on my supply of round tuits - I might get the pluggable brains
also working shortly. I kinda see how they work now.

Hm - depends if it's easier to get to than my current web site. :)

Message-ID: <Pine.GSO.4.10.9903181010060.29492-100000@bonnie.sz-sb.de>

We are running Python1.5.2b2 (with thread support) , latest DCOracle,

Some of our applications hang in about 10% when they run. We trussed
the binaries and discovered that they all sleep in a lwp_sema_p() call.
Python/thread_cthread.h seems to mention a problem with the Solaris
PThreads implementation however I can't figure out if this is the

or the Oracle libraries.

Any ideas or comments ?

Hi Thomas,

>Is there anyone that could help or give me some pointers ?


Yup, those switch options are confusing so I avoid them ;-)

First, the most helpful tool for me in working with Linux is
"git".  This is a nice character based navigation and file
management utility.  Just type git.  It came on my RH Linux
and is installed automatically without your request.  This
program is alot like the DOS Norton Commander that
I started using years ago.

So you get the distribution:
  Zope-1_10_2-linux2-x86.tgz
I use git's F6 key to rename it zope1102.tgz
to ease the long typing.
Move it to a newly created directory (F7)
named perhaps "zope". 

Then in that directory, type: 
    tar -xvzf  zope1102.tgz
A new directory is then created under your
new zope directory named:
  Zope-1_10_2-linux2-x86.tgz/
Go into this directory and type

***This is were you got stuck***

./install

***No switches!!!

Then edit the access file now in
this directory and change the obscure
username and password to your favorites
with F4 key to use "vi"  Press  i to 
insert new user/passwrd -- example:
  zope:gogo
Press escape then :wq  to save.

Then 
  ./start 
to start zope
and maybe later if you EVER want
to stop zope (who would ever WANT
to stop!, 
  ./stop.

BTW,  if you want to test the integrity
of the downloaded zope distro, only change
the t to an x as in:
    tar -xvzf  zope1102.tgz

Enjoy!!!

Ok, unstuck, whoops, stuck again.

I guess I have to do this in little baby steps.  Some sort of initiation 
ritual, I think. ;-)  Now I am getting the error message below even 
though python is clearly in the bin directory under the Zope install 
directory.

"./install: bin/python: No such file or directory"

This is the shell install script:


***
#!/bin/sh

# Get script dir
if [ -n "`echo $0|sed -e 's%[^/]%%'`" ]; then
  PYTHONHOME=`echo $0 | sed -e 's%/[a-z.]*$%%'`
  cd $PYTHONHOME
else
  PYTHONHOME=.
fi

export PYTHONHOME
bin/python inst/product_install.py $*
***

A little different than the PERL I am used to seeing, but I've managed to 
make heads-and-tails of the thing.


- I checked the location of python in the Zope install dir, ok.
- I checked to ensure that the sh shell was in the bin/ dir, ok.


Next up, re-upload the Zope file and check for a corrupted archive.


Any other ideas ?

Hope you don't mind me butting in, but if you just want to check out Zope
very quickly, run the Windows version on 95/98/NT.  It was nothing to
install, and I was playing with Zope two minutes after downloading it.
Python is also a snap to insall on Windows.

Subject: [Zope] Parsing XML into/out of the database
Message-ID: <199903182236.WAA24270@cheviot.ncl.ac.uk>

Hi all,

I have an application that consists of 140+ XML documents, roughly 100k
bytes each that I want to be able to query (using XSL pattern matching at
present) and output to XML/HTML and RTF format. This will happen in real
time (if at all possible).

At the moment, my XML documents are held as files in a real file system
(sacrilige! :). However, I'd like to get them into the database structure if
at all possible, as I imagine it will make things easier in terms of
searching. For example, the XML file

<?xml version="1.0"?>
<document title="Cell Biology">
<topic title="introduction" id="cb1">
    Cell Biology is a good thing. If it weren't for Cell Biology, you
    wouldn't be around.
</topic>
<topic title="lectures" id="cb2">
    <topic title="lecture" id="cb2" num="1">
    This is lecture 1.
    </topic>
<topic title="lecture" id="cb3" num="2">
    This is lecture 2.
</topic>
<topic title="reading list" id="cb4">
    <topic title="bok" id="cb5">
        A big bok
    </topic>
</topic>
</topic>

Would lend itself to creation in the Zope database really easily (I think).
XML elements (document, topic) and attributes such as id (used to uniquely
identify an element) and title would be properties of the DTML
document/method. So long as the id numbers were properly arranged, it should
be *relatively* (good word that!) simple to recreate the original XML
document. I assume that parsing the XML (in actual fact, the DTML doc/method
would consist of *very little* XML I think, it all being taken care of in
properties) to create HTML would be, again, relatively easy (my own tendency
is to use the 'title' attribute as a class identifier for cascading style
sheets).

My question is, do people think that this idea could fly? I have spent *a
long time* looking at how to get our Word (sorry for saying that!) documents
into a format that means they can be easily put into a database and thereby
benefit from all the good things that means. Several cul-de-sacs and wasted
weekends later, it seems to me that Zope is coming out to be the closest
thing to a solution for my problem...

(I know from off-list discussions that there's a definite 'weirdness' about
how people have been wanting/needing to implement things and then finding
that (a) Zope does it already, (b) there's a product available or (c)
someones working on it... !).

any thoughts, as usual, greatly appreciated.
tone.

Message-ID: <Pine.LNX.3.96.990318144553.4537B-100000@taos.kavi.com>

I've been messing around with using direct traveral on the ZSQL methods.
I'm having a problem getting the traveral to work with anything more than
one level of depth, eg:

http://zope.kavi.com/mem/2/comp_admin/contacts/

Where 'mem' is the ZSQL query (that takes one arg), and the arg is '2'.
But it does work in this case:

http://zope.kavi.com/comp_admin/contacts/mem/2/

Is this a restriction on the use of ZSQL direct traveral, or am I doing
something wrong.

If this is a restriction on how you can use direct traversal, I was
wondering why, and if it'd be possible to 'fix' this. If so, I'm willing
to do it and supply a patch, I assume this is functionality comes from
Zope/lib/python/Shared/DC/ZRDB/DA.py, either in the DA.__call__ or in the 
Traverse object. I'll have to mess around with it a bit to figure out
exactely whats going on (but I figured I'd ask about it first).

This is more or less what I did for my original FAQ product (but on a much
smaller scale). I found out XML docs map nicely onto Zope's DB structure.
I think you should give it a try because really it is not much effort to
implement.

Since the FAQ development has moved to zdp.zope.org my site is no longer
needed so I created a guest account with the following authentication
info:

guest
bobo

at URL http://www.gaaros.com:9673

You can visit it and see my approach to the problem. I should also include
the code of the external method that creates the Zope objects. (I believe
a couple of more zopistas asked me for source access so here is your
chance.) I have backed up Zope's DB so you can mess around as much as you
want.

Without seeing your folder hierarchy, I'm not quite sure what's going on.
Frankly, my head feels like it's going to explode when I try and figure
out how your second example even worked. What are comp_admin and contacts?
Folders? Where do they fit in your folder hierarchy?

I have an event calendar, in which I use direct traversal of a ZSQL Method
to display a particular event. My hierarchy is as follows:

+ events [Folder]
  - event_details_html [DTML Method]
  - dbFindEventById [ZSQL Method]

My dbFindEventById method takes on parameter, event_id. To use direct
traversal on my dbFindEventById query, using the event_details_html file
to display the details of the event with event_id of 2 requires the
following URL:

  http://localhost/events/dbFindEventById/event_id/2/event_details_html

At first, I tried:

  http://localhost/events/dbFindEventById/2/event_details_html

which looks very close to your first example, and it did not work. Then I
realized you are required to specify the name of the parameter in the URL
as well, so I added event_id before the 2, and I was off to the races.

I'm sure I've misunderstood your problem somewhere, and if I did, I
apologize for spouting off nonsense. But, I figured this just might help,
since I got tripped up when I first tried to use direct traversal, also.
Better safe than sorry. :^)

Ok, a bit more info...

mem 		ZSQL method (on top level - stands for member company)
+ comp_admin  	folder (company admin)
  + contacts	folder (contact info for that company)

contacts has an index_html which uses information returned from the mem
query (its not how I use it, it won't even display with just #var).

'mem' takes one argument: comp_id (of which 2 is a test case)

Actually, I've found the reverse to be true. When I try:

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

I get this error:

Invalid integer value for comp_id 

Traceback (innermost last):

If I use creosote.spew to output the comp_id value before calling the
query (I made spew an external method on the top level, this has come in
very handy), the value resolves to 'comp_id'.

But when I don't use the comp_id arg (like in the original example, and
spew shows the value to be 2), it works fine as long as the method using
it is the next on the URL.

Actually you are close, but in your example you use it as I said it works.
In your code app can you do something like this (fictional change of your
example):

http://localhost/events/dbFindEventById/ 
	event_id/2/modify_event/edit_event_details_html

(should be all one line)

Make more sense now?

BTW, thanks for the help. :)

Ok, I think I figured out why we have different (opposite) results in
this. I don't think you checked the "Allow direct traversal" checkbox on
the advanced management page for the ZSQL method. If I unchecked it, then
I could traverse like so...

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

After checking it, I could traverse in this way...

http://zope.kavi.com/mem/2/comp_admin/contacts/

Strange... :)

Still doesn't address my original problem thought. I still can't get
access to any of the results of the 'mem/2' query anywhere other than
directly after it (on the url). 

Ie. 

http://zope.kavi.com/mem/2/comp_admin/contacts/index_html 

Doesn't work, but...

http://zope.kavi.com/mem/2/test_html 

Does... 

I'm still digging through the ZSQL code looking for a way to fix this.
I'll let everyone know once I've figured it out.

Ok, here's a thought. What about trying:

  http://zope.kavi.com/comp_admin/contacts/mem/2/index_html

Since the 'mem' ZSQL Method is in your root folder, it will be acquired
by all folders below the root folder. Thus, the URL above should tell
ZPublisher to go to the /comp_admin/contacts folder, then call the
acquired 'mem' ZSQL method, with 2 as an argument, and using index_html to
display the results. (Assuming the parameter name is not required, because
you have checked 'Allow direct traversal', as you described.)

I am curious to know what the 'Allow direct traversal' button does on the
Advanced tab. Can anyone else here comment on that? Frankly, I didn't know
it existed, as I've been able to use direct traversal just fine without
it. It's curious to me that it changes the behavior of the traversal in
the manner you demonstrated. I'm dying to know why. :^)

In this case, I would probably do:

  http://localhost/events/modify_event/dbFindEventById/
         event_id/2/edit_event_details_html

Hey folks,
Boy I'm feeling mighty dumb, but I just now, after maybe 8 hours of 
zope stuff (late night after work), discovered where the tracebacks were 
hiding from me.  I searched this list, but never actually saw where they 
were printed, I finally saw it in the Trinkets Tutorial which I'm sure I read 
earlier <sigh>.  So just in case someone else is out there in the same 
boat as I was - the tracebacks are comments in the html error page. 
DOH!

You'll want to check out the doc/WEBSERVER.txt file under your Zope
directory. Make sure your running a recent enough version of Apache
and have mod_rewrite installed. Then, you need to configure rewrite
rules so that Apache will pass authentication info through to Zope.

Simon,
AFAIK, all the EFNet servers require identd.  If you are running ip-masq 
then you need midentd.  You can find it at rpmfind website 
( http://rpmfind.net/RPM )

Sorry, my mistake, there isn't an rpm for midentd... here's the url

Heck, identd is a trivial enough protocol. You can always just
write one in 2 lines of python which just returns "sod off" as the 
username. :)

That EFnet require it is somewhat puzzling.

Message-ID: <v04011701b3179cd6f425@[204.244.68.39]>

I installed the  Zope binary on a linux box, and everything went well. User
authentication worked successfully with Apache using the 'REMOTE USER'
environment variable. Then I tried to get ZMySQLDA to work, but I couldn't
get the Zope Python install to find 'libmysqlclient'. I got a build of
Python 1.5.1 to successfully import MySQL.

So I decided to reinstall Zope from source, so that I could use my own
Python. The source Zope built okay, but when I tried to start Zope through
the web browser I got an "Internal Server Error" message from Apache, the
error log said I had a "Premature end of script header". I've checked
permission on the var dir and user authentication still seems to work fine.
I couldn't figure out why I was getting the error, so I tried re-installing
the binary distribution of Zope. No luck there either, I get the same
"premature end of script header" error message. I've checked the Zope.cgi
file, and it seems o.k.

Does anyone have any idea why Zope.cgi is failing on me? Is there something
I have to do to Apache or Zope if I've removed the Zope folder and then
untarred and re-installed a new Zope?

Don't know if this'll help, but this is what I get when I run Zope.cgi from
the command line:

Many thanks Pavlos - I saw that the Doc effort had moved to zdp.zope.org and
is using structured text, and thought that it was a bit of an opportunity
lost (no disrespect to the Zope Doc Effort of course) as I was amazed to see
that the FAQ system you wrote was XML-based and hence easily extensible.

Thats excellent! - thanks a lot. I'll be snooping around later on once I get
into work - I had looked at XMLConfig almost straight away, but had to put
it to one side whilst I got to grips with Zope  (and Python!) fundamentals.

At least I've got somewhere to start from now...

Also, and this is important!

Don't forget to make sure that the cgi driectory holding Zope.cgi has
ExecCGI turned on.

As I said this is important, later versions of Apache don't turn it on by
default.

The error you get when running Zope.cgi from the command line is a red
herring, ignore it?

It comes about because SCRIPT_NAME is set by the Web Server and as you
aren't running it through such, you will get errors telling you that various
ENVVARS do not exist.

As to your other problem, hmm, it still sounds as if the var dir is not set
correctly, maybe?

Message-ID: <36F26982.C8DBAF5@icube.it>

Hi everybody,

I am in a FAQish problem. I am using ZopeHTTPServer for setting up a
complex intranet site. However, access control do not seem to work at
all.

Either I can build a public site (which is viewable by everybody), or
I have to use SuperUser passwd to enter in a private site.

I would like to allow user A to see folder X but not folder Y, and so
on. I have created users, assigned roles, but it seems not to work.

BTW, cut & paste do not seem to work at all.

Any suggestions ?

Thanks.

Message-ID: <Pine.LNX.3.95.990319091005.28046A-100000@animal.blarg.net>

I'm resending this to the zope list, because I didn't get any response
from the zope-dev list.

Hi.

I have made my first Product (a little message wall that people can post
colored messages to), but I am having some trouble with the Security tab.
When I press the tab, I get a Permissions screen that looks as it should,
but when I click the change button (no matter what permissions I change,
if any), I get the following error:

Sorry, an error occurred.

Traceback (innermost last):
  File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 877, in

  File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 590, in

    (Object: RoleManager)
  File /usr/local/zope/lib/python/AccessControl/Permission.py, line 166,
in setRoles
AttributeError: manage_main

I don't doubt that I am causing this, but since it isn't occuring in my
code, I don't know how to go about finding the source of the problem.

Thanks for any help you can give.

Subject: [Zope] frames and external method lookups
Message-ID: <9903190931.ZM14151@saab.coinet.com>

I have a DTML Document that references an External Method. This document
is embedded inside another DTML document. If I view this document, then
the page is rendered correctly. If I now take this document and reference
it from a <frame> tag, Zope complains and says it can't find the external
method. What's different here that causing me problems?

Here's some more details, including the traceback:

1. Zope-1.10.2-linux2-x86
2. The innermost DTML docuemnt (lighttablebar) refers to the extermal method
   like this:
	<!--#in expr="looprange(ltblSize)"-->
   'looprange' is my external method and is located in the top level folder
   'ltblSize' is a property of the document that "includes" this document.
   This innermost DTML docuemnt is also located in the top-level folder.
3. The next DTML document (lighttable_frame) includes the previous document
   with a simple #var command (in between some other html stuff):
	<!--#var lighttablebar-->
   This document has a property named 'ltblSize' defined as 6.
   This document lives two folders down from the top-level folder
   I can use the View tab in the manager to see the rendition of this page
   and it looks just fine and there are no complaints about looprange().
4. If I include the previous DTML document in another DTML document that
   is specifying some frames, e.g.:
	<html>
	<head>
	<title>Stock Book</title>
	</head>
	<frameset rows="60%,40%">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/lighttable_frame" name="ltable_win">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/navigate_frame" name="nav_win">
	</frameset>
	</html>
   When I use the View tab to see what this page looks like, I get the two
   frames, but in the lighttable_frame frame, I get an error message about
   looprange being undefined:
---- start of traceback message ----
The specified module, looprange, couldn't be opened.

Traceback (innermost last):

---- end of traceback message ----

So again, what is happening when the DTML doc is being refered to inside a
frame
that is different than not in a frame (and more to the point, how do I get
around this apparent problem)?

Zope (up to 1.10.x) expects every managed object to have a manage_main
method that provides the default management interface for the object.

You need to rename or create an alias from your default management
method to manage_main.

In Zope 1.10, there will be a new inherited method, manage_workspace, 
which should not be overridden, that picks the first item in you
manage_options as the default management interface.  This gives 
you more flexibility in naming and will allow more dynamic view
management.

Oh, I see.  So the manage_main I see is actually being acquired from the
folder my product instance is installed in?  If so that would explain why
adding things to it actually adds things to it's parent folder.

If I write a manage_main method, will it start magically working, or do I
need to add it to __init__.methods and/or one of the __ac_permissions__
tuples?

I apologize if for the off-topic nature of this post, but felt it was
too important to ignore.

Microsoft has released IE5, which is non-compliant with many of the
standards that Microsoft has helped author. As widespread compliance to
standards is one of the things that will greatly enhance Zopes success
in the marketplace (i.e. WebDAV, XML-RPC), I felt that this issue
deserved to be aired here too.

   Recently Microsoft released their 5.0 browser and after all this time

Subject: [Zope] Web Application Software
Message-ID: <36F2C006.9D7E89C9@amvalue.com>

I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Ahh yes, Glenn "Master of Self-Promotion" Davis has found a cause with
which to attach his persona.  Glenn got his start at InfiNet, our former
majority owner.  I remember when he shared a 10x10 office with the other
Mac person there.

I love the "I'm not asking as Mr. Mega Big-wig, nor as My. Hyper Star,
I'm asking as a humble guy that singlehandedly saved the web" part.
That paragraph is so pathetic, I can't believe he actually wrote it.

IMO opinion, the only cause he is advancing is himself.  It's a shame,
because browser vendors _do_ need to be beaten into standards compliance
and away from bait-and-switch.

Ok, but what do you think of using the three templated emails? I feel

I believe the current agreement that Digital Creations has reached with
Sam Rushing (the author of Medusa) allows for open-source-style
distribution of ZServer so long as it's used with Zope.  Paul can
probably corret the exact legal situation, but basically DC bought an
unlimited license to give it away ... say thank you :-)

OK, I agree, and I ought to just focus on his words rather than on him.
Public retraction on the personal stuff, BUT I absolutely stand behind
taking offense at the words.  If you're going to lead an offensive based
on principal, make the self-aggrandizement a bit more subtle.

Hmm, didn't turn out to be much of a retraction. :^)

We reached a mutually agreeable arrangement whereby Medusa could become
the core for our object publishing system, under the Zope license.
Definately turned out to be a win-win-win (Sam, DC, and Zope).

AFAIK, ZServer was released (including Medusa) under the same license as
the rest of Zope. Which means that all of it is free software, including
the medusa code it contains.

Nope.

> 2) Is it purchased from Digital Creations?

Yes. At the moment, we are selling Collector. A number of
copies have been sold already. There are a couple of things
to note about a few of the packages that we have been
selling (relatively privately lately):

1) Most have little documentation (read the source Luke :-)

2) Our license specifically reserves the right to give the
software away at some future point (so you need to realize
you are paying to get it now, and shouldn't be annoyed
when/if others get it for free!)

3) Our license specifically prohibits redistribution, or the
creation of derivative works (for distribution)

4) We permit unlimited internal use of the code, including
operating public websites

5) We offer email-based support for 90 days (for 2 contacts
usually)

6) The license is for 5 developers only. If you have more,
you buy more copies

7) Additional support options are available for purchase.

The point of the above isn't to make a lot of money. We're
selling more copies than we anticipated, but hardly enough
to make this our business model. The point of charging is to
cover the inevitable support costs of shipping a product
that has little documentation, but is more technically
advanced to use than the content-oriented Zope general
release.

A secondary benefit is that people who purchase now are
clearly motivated to use the product(s). Therefore, the
support questions tend to be focused around real-world use
of the products, and help us make them more robust for the
inevitable Open Source release (whenever that might be).

So, which products are we currently offering for sale?

1) Collector
2) Z Tables
3) Z Network Client
4) Infoseek DA

In general, pricing is at $1,500 per package. The exception
in the above list is Collector, which is $2,000. The reason?
It makes heavy use of Z Tables, so essentially you are
getting two products for the price on 1.3333 products :-).

Those who wish to discuss this (either to become customers,
or to tell me that we're "off base") should write to me
directly, and _not_ post to the list.

I know that a number of people responded to this already,
including Paul. However, he didn't give as concrete response
as this direct question requests.

The answer is _yes_, Digital Creations most definitely paid
_real money_ to Sam for the right to embed parts of Medusa
in ZServer. However, the intent of the license is to allow
unlimited, free, Open Source(tm) use, within the Zope
environment. If you don't intend to use Zope, then you
should be licensing Medusa separately from Sam Rushing. We
highly recommend it (obviously), and have put our money
where our mouth is.

The reason that this is an important question to answer is
that we are so committed to the Open Source movement, that
not only do we release stuff that we wrote, but when
appropriate, we will invest hard cash to further the
community as well (ZServer being but one example).

<NOTE>I do not know much about btrieve.</NOTE>

<btrieve>
If you can make btrieve a data source you are home free. All you need is the
connector/drivers.

http://www.zope.org/Download/Adapters

Also look into:

http://www.python.org/download/Contributed.html#Database

Typically these modules make there way into zope as they are existing python
modules.
Actually I would gather that Btrieve has a c interface that would make a
great product.

</btrieve>

<dev>

As with all projects .... it depends.

Using attributes is the key to zope. If you take advantage of its ability to
store session variables Zope is far better than other solutions because you
do not need a database to store info during a transaction, you can simply
write it to an attribute in zope thus lowering the # database calls.

I guess the implementation depends on allot of variables that were not
listed in your email.

1. # of concurrent users
2. # of queries and "How databasy is the application? Big Queries?
OnChange?"
3. Specifics on your data model
4. # of tasks required
5. How OO(Object Oriented) are you?

It is a difficult concept to cover but developmental access to ZOPE is
remote by nature. Anything you can do in Zope is accessible anywhere, by
anyone else. Except for installing modules and products, you do not need
machine access ---> Everything is done online and inside of Zope. It is
convenient that way.

Look into the bug collector for the ZOPE site. It allows many levels of
access to the bug database except there is not database just Ztables. It
might be just the ticket.
http://www.zope.org/Collector

Also take a look at the example folder here 
http://www.zope.org/Download/Contrib
Specifically the DTML EXAMPLE FOLDER --> IT WILL GIVE YOU LOTS O' CODE and
HINTS 
</dev>

Just think in OO and Zope will work.

Best of luck.

Subject: [Zope] Web Application Software


I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Subject: [Zope] Why do I have to reimport External Methods ?
Message-ID: <99032019551700.01550@alpha>

Hi all !


I am new to Zope, and I have a problem with External Methods.

Everytime I change the implementation of my file in Extensions/test.py I have
to reimport the External Method to see the changes.

What am I doing wrong ? I just want the changes I made to the source
code to be reflected when I reload a page !

I hope someone can explain what I am doing wrong here.

Maik Röder


Some more details:

I have a folder called

VMBI

and an external method

test

in it. Everything works just fine,  the

index_html

file has a call to the external method, which just prints "Hello World!"

 <!--#var test-->

So the following URL

http://localhost:9673/VMBI/test

prints

Hello World !

But when I change the original source code to print for example

Hello Zope !

Then upon reloading the web page 

http://localhost:9673/VMBI/test

there still is printed

Hello World !

What's going on here ?

You don't have to delete and recreate an External Method each time you
change it's file. But you do have to go back to its properties page and
hit the "Edit" button to reload its module (this is actually a nice
feature of python, being able to reload modules at run time).

> What am I doing wrong ? I just want the changes I made to the source

Well, it may be possible to stat the External Methods file each time its
used, and reload it if its changed (you'd have to store its last
modification time somewhere to compare against). This probably isn't done
for performance reasons. Perhaps it could be linked to the BOBO_DEBUG_MODE
environmental variable or something to address this issue.

Is there a similar way to reload code for a Product, or is the
shutdown/restart of Zope necessary?

If I do have to continue the shutdown/restart process, is there any way of
tuning PCGI so that it loads up faster?

Thanks.

But wouldn't that kill the Zope process instead of having it shut itself
down?  How gracefully does Zope exit when receiving a SIGTERM?

A simple way that works for me is, when debugging, have a normal cgi version
postfixed with -c and use that.  This brings me to another thing:  the default
zope distribution doesn't include ZCGI and friends, I assume because Zope
users supposedly have no interest in normal cgi.  I think it should be
included anyway, so that Full Zope is a superset of Only ZP/ZT.  That's more
intuitive, and then you don't have to download both if you want to use both :)
And ZCGI.py is only a small text file, after all.  And perhaps zope users are
interested in ZCGI after all, or does zope make assumptions about running
persistently (can't see how it could, without violating http's statelessness).

And as far as tuning pcgi: you could shorten pcgi_socket():delay
or the 2 second sleep() at the end of pcgiStartProc().  The first one could
probably be pretty safely shortened with the miniscule cost of a chance of a
few extra connect() calls, but the second one should probably stay the same,
although I'm not clear on its purpose (give time for the child to sort itself
out?).

Here's a random question: how come the win32 pcgiConnect uses CONNDELAY
(defined in pcgi.h as 1), while the unix version says int delay=1; ?

See, that's the problem with open source: all sorts of grubby randoms can go
rooting through your code :)

You may season to taste.  The 2 second pause seemed safe enough 
on most tested systems, since we're flying blind.  We've reserved
an extra header byte to designate out-of-band data that could be 
much smarter about how to handle this, eventually.

I don't have the code here, but it's probably trying to
avoid some problem that I encountered when it was 
missing <wink>.

Probably historical flotsam.  The win32 portion of pcgi is
almost a completely separate product and only coexists with
its Unix cousin by virtue of an overabundance of #ifdef 
clauses. 

I've mentioned this before, but it probably won't hurt to 
repeat.  I don't think the win32 version of pcgi as the best 
solution for this sort of thing.  It's mainly there to fill 
out a niche.  Process launch is more expensive under Windows 
than Unix, so the Medusa/ZServer approach is probably more 
sensible in that environment, where good performance is
desired.

Hi!

I'm working on an intranet site (using Zope). Now I need to make the site searchable. Tried using htdig, but without luck (should it work with zopesites?). Now I wonder - is there a builtin feature in zope that can fix my problem, or are there other programs like htdig that works with zope? 

Help is much appreciated!

Subject: [Zope] one 'document' in many 'folders'
Message-ID: <199903221343.IAA17544@gem.lightlink.com>

As a demonstration project to try and get a client to go with Zope, 
I'm converting a newsfeed database that I had originally built using 
Perl.

The object of the game is to pull fresh articles from a Reuters 
server every two hours and put them in a bin. A human editor goes 
through the bin, culls and sorts the articles, edits where 
appropriate.

One article may appear in more than one section of the site. For 
example, an article titled "Zope Is Cool" might appear in the 
Python, Web Development, and Open Source sections. Each 
section has its own contents page.

This is where I get confused. My Perl application simply used the 
filesystem as a database, and generated three separate static 
copies of "Zope Is Cool", placing one in each of  three directories: 
/python, /web_development, and /open_source. I suspect there are 
much better ways to do it in Zope, but how do I organize things?

My naive idea is to make each article a Document, one of whose 
properties is a list (or dictionary) of categories in which it should be 
placed. Generating each section's contents page would then take 
some figuring out, and performance on doing the contents page 
would be a concern.

If there's a better way, I'd certainly appreciate hearing about it.

Signed,

Correct me if I'm wrong, but the only way I see to do this *inside*
the Zope application is to keep all your articles inside one folder
(pool) and have key documents in your tree structure which 
reference an article in the pool.

I don't know if problems appear when you establish an acyclic
directed graph structure in the object hierarchy itself (I asked
the question myself months ago without an answer).
I see no point why it shouldn't work, but it is not maintained 
by the application.

An interesting fact is that your object's properties vary when
accessed by different paths due to the acquisition structure.
An object inside Zope's database (again, correct me, if...)
doesn't know about its father. It only knows about its sons,
the aq_parent path is constructed on each access.

Would also like to hear more about this...

Check out the FAQ on http://zdp.zope.org  it has some information on how
to use the built-in searching capabilities :-)  It's not perfect, and

This application sounds similar to stuff that I (and others on this list are
trying to accomplish).

My immediate term solution is to make multiple copies of the article in the
ZDB. I agree that this is suboptimal.

Paul@DC has mentioned that they are working on a "Catalog" feature that they
would like to integrate with Zope. This feature will be *perfect* for this
application (and many others). Unfortunately, I don't think this is on the
very near term radar scope.

Depending on how far out Catalog is, and when I manage to finish off the
basic necessities for my sites, I was thinking of delving into Zope's btree
stuff and trying to put together some kind of search interface. Right now,
though, I've still got a bunch of work to do before I get to that point.

What a great mailing list! I posted my question, shovelled the 
driveway (Ithaca NY, 8" of heavy wet snow last night), had 
breakfast and an extra cup of coffee, then came back to my desk 
to find 2 good answers. Thanks Stefan and Kevin.

Well, on the one hand I'm pleased to hear that my question wasn't 
trivial. But I'm disappointed to hear that my problem is difficult.

I'm competing against Cold Fusion here, and the problem resolves 
itself pretty easily with linked tables. (At least until I actually try to 
write the code.) So maybe I should just co-opt the competition and 
use ZSQL? But the odb is so nice, I really want to make it work 
that way.

I don't really need for the URLs to look like a directory structure:
instead of /open_source/zopeiscool, it would be okay for the article 
URL to be /zopeiscool?section=open_source. But that still leaves 
the problem of generating a contents page for each section. I 
suppose I could have a script that periodically-or-on-demand walks 
through the articles and generates a fresh static contents page for 
each section. Seems kind of non-zopish, but that might be the 
best way to get decent rendering performance on the contents 
page anyway. (The site is very active.)

I suggest you try out your idea first. It sounds simple and
straightforward and performance won't be a problem unless you have too
many entries (but I am only guessing).

> some figuring out,

Assuming you have a folder Entries and folders Python and Zope. An entry
in the entries folder is a DTML doc with a lines property named sections
containing the sections (folder names) where the given entry belongs to.
In the root folder you have a DTML method like: (untested)

<H1><!--# var title--> contents:</H1>
<!--# with "_.namespace(section_title=_['title']"-->
<!--# in Entries-->
<!--# if "section_title in sections"-->
... Do something (ie link to the entry or render the entry etc ...
<!--# /if-->
<!--# /in-->
<!--# /with-->

you can call this method from inside the index_html method in each
section's folder.

This is great, I'm planning on doing exactly this myself. 

Roughly, if I don't want sluggish performance, what would the upper limit
be in regard to number of articles? Are we talking hundreds of articles?
Thousands?

Sorry to post a commercial plug here, but it seems in stride
with my post from this weekend to another question
(Collector).

Basically, Z Tables would be a pretty perfect fit (IMHO). I
realize that you too realize that (sort of), because you
suggested going the ZSQL route. Clearly, there are
similarities. But, Z Tables has already been independently
benchmarked as _kicking a**_ performance-wise, and is also
more closely aligned with the gestalt that you indicated you
liked about the object database.

Just a thought (and a few bucks, of course :-).

Hi Phil,
Sorry I didn't make things clear (maybe I'll update the list?).  Yes I 
solved my problem and feel really dumb.  I didn't realize that the 
traceback is in the error page as a comment.  Once I found that out, I 
saw immediately that the arguments passed in had a couple of extra 
fields that I didn't use (the master and detail tables share some initial 
fields).  I took them out of the sql statement and the form, but I didn't 
remove them from the argument list.  (Just an FYI, the system allows 
you to add additional detail records, the first one is autogenerated from 
the master)

Unless you do something tricky, I doubt you will be able to get normal
search engines to work with a Zope site, since I belive that most search
engines want to read HTML files from the filesystem for indexing.

>Now I wonder - is there a builtin feature in zope that can fix my problem, or

Right now there is a simple Find mechanism, but it isn't really a robust
search facility. In addition, Zope now includes low-level Python packages
for indexing. So the basic tools are there, but there isn't an easy to use,
out of the box search engine in Zope.

We're working on a much better solution to this problem. We're calling it
Zope Cataloging, and it is currently built with ZTables. I believe that
like ZTables, Zope Cataloging will eventually be free, and become a core
part of Zope. Unfortunately, I do not have a timeline. Sorry. :-(

As long as it's you (i.e. important cause of Zope's open sourcing)
posting commercial plugs on zope@zope.org, I doubt many people would
mind. :)

[ZTables]

Although I'm still a complete ZTables newbie, I've seen ZTables come up
repeatedly when there are similar design problems. This would indeed
seem to indicate ZTables are a good fit. :)

[Apologies if this post is considered off-topic on this list]

You might want to try Webinator, an outstanding search engine available at:

http://www.thunderstone.com/webinator/

It's free to use for up to 10,000 documents. It works by fetching documents
over HTTP (not your file system), so it should work with Zope. However, the
free version requires an Internet connection to check with the license
server, so it might be impractical for an intranet soluition without full
Internet access.


Hope That Helps,

/J

I agree :-). Of course, this is precisely why we intend to
release it (eventually) as Open Source(tm). We truly feel
that the community will benefit, so we will release it. In
the meantime, we're swamped, and prioritizing workload based
on hard currency makes for simple decisions...

I just thought a little more about the approach having a pool
and some proxy objects that refer to the pool.

I think it could be made quite neat when using just the 
following code for the proxies (DTML documents):

    <!--#var "RESPONSE.redirect ('/pool/'+id())"-->

So you just need to put zope_is_cool inside your pool
and add DTML documents with the above code under
the same id to your folder structure wherever you like.
Just check it out.

Two caveats: 
- You have to use DTML documents, not methods, otherwise
  id() refers to the folder's id
- Make sure that zope_is_cool really exists inside your
  pool, or you get an infinite redirection!
  (zope_is_cool is not found in the pool and then sought for
  along the aquisiton path, which refers to zope_is_cool itself,
  which redirects to the pool which ...)

Maybe this could be even generalized to some kind of
"symbolic link" product. Ideas anyone?

An alternate solution could be something like <!--#var "_.getattr(pool,
id)"--> for your "link" methods. I think this would take better advantage of
acquisition. A document could pick up its headers and footers from the
category, instead of the pool. It does seem like someone could create a
"symlink" product pretty easily.

Message-ID: <36F69DC5.2FBB044@eq.uc.pt>

Zope is great. It's so great that I guess I'm trying to use it for doing
something different from what zope it's expected to do. I want to make
some SQL scripts to access different databases and collect the data in a
new table. That I can do with the following external method that calls
see_data and put_data ZSQLMethods

def get_data(self):
    result = self.see_data()
    self.put_data(value=result._data[0][1])
    return None  

Then I wish to make this kind of data management automatic every hour. I
dug in the sources and I found out the Scheduler class, which I think is
what I need (is it?). But I'm having some trouble using it. This was the
external method I tried (without success).

def eventGetData(self):
    rev = RegularEvent(get_data,(),interval=60)
    self.schedule(rev)
    return(None)      

It seems that RegularEvent is not available. Besides, is schedule
available trough acquisition in the folder? 

Can someone give me some light on this. I don't even know if it's
possible to use the Scheduler with external methods so it would be great
at least to know I'm in the right path.

Thanks

Looking for some enlightenment:
<set learning on>

I understand that Ztables was formerly Tabula an
object database.  

If one were starting from scratch without legacy data
would it make sense to use an object database instead
of a relational database?  

If so, is ZTables/Tabula a full, robust database
system that can scale up and exceed the
features of Oracle or SQLxxx databases?

What are the pros/cons of Object vs
Relational databases.

Currently it appears that Ztables/Tabula
is priced at $1,500 but eventually may become
open source.

From recent posts on the list

*"Make site searchable"
*"one 'document' in many 'folders'"

It seems like Ztables would be an Ideal 
solution to these problems.  ie, rather
than the kludge of multiple copies
of the SAME document, ONE copy in
the database.  Also, searching by
key or full text would be possible.

But for further enlightenment, can anyone
point to good examples on the web of the 
use of ZTables/Tabula?

woops, your request to <set learning off>

By nature anything named "tabula" wouldn't be a pure object database :-)
OODB don't have tables, tables are a relational concept, and I believe
ZTables is a relational database last I checked---b ut then I've never
seen it either, but the implications by Jim/Paul/et. al. are that it is
something along these lines.

Maybe, it all depends on your data, the interdependencies, and what kind
of queries you run, how ad-hoc, and what level of reporting tools you
need.  OODB are mature, but their supporting structure (reporting tools,
modeling tools, and more importantly Zen :-) are quite lacking in my
opinion).

i doubt it, but then, Oracle/et al are not necessarily the right answer
for all problem sets, it's not a one hammer fits all nails solution.

> What are the pros/cons of Object vs
> Relational databases.

Dear gods, there's thousands of papers written on this topic ;-)
References are faster in OODB, ad-hoc is easier in RDB, and there are a
billion other blends... it's also necessasry to understand network
databases in my mind before you approach OODB.

You just can't generalize to this level, it's impossible, and a "quick"
overview of OODB v. Relational would require about 30 pages :-)

Subject: [Zope] passings vars to sql method
Message-ID: <36F6C357.1F277AE3@GestaltTechnology.com>

Zopists,

    I run into a problem. I have a DTML Methos that call an SQL Method.
The SQL method, displayTasks, has two parameters, userID and statusID.

The DTML method does have access to the variables userID and statusID
prior to calling the sql method with a <!--#in--> tag.

The DTML method looks like this:

<!--#var standard_html_header-->
<H2> <!--#var document_title--></H2>
<P><b><!--#in getUsers--><!--#var name--><!--#/in--></b></P>
List of tasks: <form action=displayUser method=post>

<SELECT NAME=statusID>
<!--#in listStatus-->
<OPTION VALUE=<!--#var statusID-->><!--#var keyword-->
<!--#/in-->
</SELECTED>
<input type=hidden name=userID value=<!--#var userID-->>
</form>
<table>
<!--#in displayTasks-->
<tr><td><!--#var taskID--></td><td><!--#var description--></td><!--#var
priority--><td><!--#var </td></tr>
<!--#/in-->
</table>
<!--#var standard_html_footer-->



THE SQL methos look like this:
select *
from task_schedule where
task_schedule.userID = <!--#sqlvar userID type=string--> AND
task_schedule.statusID = <!--#sqlvar statusID type=int-->

--------------------------------------------------
I basically can't run the query because it cannot get a value for userID
or statusID.
How do I pass these vars to the sql method from a dtml method???

Thanks in advance,

Freddy, did you make the variables you are passing to your SQL method
parameters of the SQL method?  If not they won't be looked up in the
request, they will only be searched via acquisition.

This is described in the Z SQL guide where it shows the order of lookup
for SQL method parameters.

Have fun!

Message-ID: <199903230130.SAA00571@stout.atd.ucar.edu>

I'm still experimenting with ZOPE and the FAQ tool, which uses the 
'tree' display widget.  When I add a category or a FAQ entry, these 
items seem to appear in reverse order of the order I added them.

The FAQ widget index_html DTML contains the line:
<!--#tree sort=isCategory-->

On what basis are the categories sorted?  By name of the object's 
folder?  Is there anyway to get the entries sorted in the order they 
were entered?

Thanks much!

Hi all!

I'm having a problem with running queries containing long numbers.
I found in db.py that the data type NUMBER is converted to an
integer which overflows in my case.

The errors:

Error, oci.error: (1455, 'ORA-01455: converting column overflows integer

Traceback (innermost last):

from

to
                if scale==0: type='f'

in order to force a float type, but this has no effect, it seems.

I'm sure that I'm misunderstanding something here.
Any pointers to where I can look to fix this would be greatly
appreciated.

Without having yet looked at the source(*) could this be an error
occuring in Oracle itself?

I just noticed the ORA-* which is typically an Oracle error message.

  I have no problems with other applications as long as I stick with
 floats. Notably, Zope on Windows running through ODBC has no
 problems--the values are all converted to python L types. (Hey! maybe
 I should take a look at the ODBC code...) This is what originally led
 me to believe that the problem wasn't with Oracle, but within the OCI
 interface to Zope.  
  I also thought that it also might have something to do with my Linux
 install, but SQL*Net doesn't have problems and Zope works wonderfully
 except for long numbers.

 Environment info:
 Zope 1.10.2
 ZOracleDA 2.0.0
 RedHat Linux 5.2
 Oracle Net8 Client
 Apache

Subject: [Zope] Questions about DocumentTemplate.
Message-ID: <004c01be74fe$35088aa0$0801a8c0@bobcat>

Ive started playing with DocTemplate for a project, but I will be
using it sans Zope.  I hope this is still the appropriate
place...

I want DocTemplate to expose an object model, and it seems
perfect for the task.  However, Im having trouble using "."
expressions.

Code speaks louder than words, so my code is:
##
class Spam:
	def eggs(self):
		return "Eggs"

spam=Spam()

from DocumentTemplate import *
ss=HTML('Eggs are <!--#var expr="spam.eggs()"-->')
print ss(spam=spam)

ss=String('Eggs are %(spam.eggs)s')
print ss(spam=spam)
##

What Im hoping to do should be quite obvious - I want to refer to
"spam.eggs" in the DTML.

With the HTML example, #var expr="spam.eggs()" is the best I can
get.  It seems ugly to me, and I feel there must be a better way.

Using the String example, I can't make _anything_ work.

Any I missing something?  Is there something I can do so that
String('Eggs are %(spam.eggs)s') does what I want?

Please CC me - Im not on the list (but did peruse the archives
before mailing...)

Thanks,

Mark.

Hi!

How come this code (from within index_html) doesn't show files and folders
within my folder?

<!--#tree branches="objectValues(['Folder', 'File'])"-->
<!--#var id-->
<!--#/tree--> 

(<!--#tree--> <!--#var id--> <!--#/tree-->) doesn't work either)

This is using Zope 1.10.2 on linux (2.0.35)

All I get is a blank screen - how come??

Here's an alternative that works:

from DocumentTemplate import HTML
class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()
print s.ss(s)

and a second choice:

from DocumentTemplate import HTML

class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()
print s.ss(s)

Thanks for the response.

My problem is that I want a deep object model.  I want the user
to be able to say "spam.eggs" or "pantry.eggs" etc.  Just using
eggs wont do - I really need it qualified.

The solution I came up with was:

class DotWrapper:
	def __init__(self, ob):
		self._obj_ = ob
	def __getattr__(self, attr):
		bits = string.split(attr, '.')
		ob = getattr(self._obj_, bits[0])
		for bit in bits[1:]:
			ob = getattr(ob, bit)
		return ob

Then:
 s=Spam()
 print s.ss(DotWrapper(s))

does pretty-much the right thing...

Thanks,

Mark.

	Small caveat: Since whitespaces could occur in an nested
attrbute
	access ("a.  b  .x") , it's better to string them first. An
alternative 
	approach for DotWrapper's __getattr__ could be (not tested):

	def __getattr__(self, attr):
	    bits = map (string.strip, string.split(attr, '.'))
	    return reduce (getattr, bits, self._obj)

If your search engine works via http it should work OK with Zope. 
Thunderstone Webinator (thunderstone.com) does this, and there's 
a free version that I think will do up to 10,000 docs. (The 
commercial version costs $700.) There's a command-line switch 
that tells Webinator to go ahead & index URLs that include /cgi-

Jeff,

I have cc'ed your question to the list, not to defer it, but to let you
pick the brains of several people who have tried, some successful, some
not, to run zope as a user in a web hosting environment.  None of us
here have tried it so we're not really the ones to ask.  It is true
there is no documentation on Zope with web hosting, perhaps your
discussion will provide information for the Zope Documentation Project,
AKA the Martijn Conspiracy.

As I understand it, the web hosting provider you pick is key to the
whole issue.  If they run the kind of environment that works with Zope,
great.  If they don't (and most probably don't by default) you must
communicate to them clearly what you want.  If they are cooperative and
cool, they will oblige you and join our Zope hosting family.  If you
can't get ahold of them and/or they don't care, your out of luck unless
you go with a Zope friendly provider of which there are two to be found
here.:

Hey Sture,
Check to see if your index_html is a DTML Document.  DTML 
Document has its own namespace and doesn't use the folder's.

If you change DTML Document to a DTML Method then you'll pick up 
the folder's files and folders.

My experience has been that if the hosting company is running Apache (many
do) and if they have mod_rewrite installed (which is probably also pretty
common), it is not *too* difficult to get Zope running in that environment.
However, many hosting companies have policies against creating long running
processes. Zope takes up a few MB of memory, which is considerably more than
an instance of Apache... so many providers are not keen on that kind of
thing. Before putting effort into trying to make Zope work in their
environment, you'll probably want to ask them if they are willing to let you
run a process that will hang out in memory all the time.

CodeIt (one of the Zope hosting companies, http://www.codeit.com) will
actually host Zope for you. You don't need to deal with building and
configuring the package at all.

This typr only affects meta-data seen by some Zope tools.

There is a similar change that needs to be made to *work around*
this problem.  In DCOracle/ociCurs.py, change:

            elif dbtype==2: # Number
                if scale:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

to:

            elif dbtype==2: # Number
                if scale or 1:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

This has the undesirable effect of causing all
numbers to be treated as ints. (This is what oracledb
does) :(  Unfortunately, you can't tell from Oracle column
meta data whether values in a column will fit into Python ints.

The right way to fix this is to implement Oracle's
NUMBER or VARNUM C data types and convert to Python
ints or longs on a case by case basis.

Right, but in this case, it's because DCOracle bound a buffer
that was too small to hold the values.

The <!--#var expr="spam.eggs()"--> is a perfectly valid way to do
it. Another way would be to use the "with" tag:

<!--#with spam-->
  <!--#var eggs-->
<!--#/with-->

Neither is really "more correct" than the other, though the with
construct is probably cleaner in situations where you use many
services of the object:

<!--#with spam-->
  <!--#var eggs-->
  <!--#var method_one-->
  <!--#var method_two-->
  <!--#var method_three-->
<!--#/with-->

Hmm - it appears that the expr support is currently broken
for the python string format syntax. We'll take a look at
that. You can, however, also use the with construct here too:

ss=String('eggs are %(with spam)[ %(eggs)s %(with)]')


Just in case you hadn't found them already, the latest DTML manuals
are on the zope site at: http://www.zope.org/Documentation/Guides/DTML.
They contain some examples that try to demonstrate common DTML idioms.

First, you should use branches_expr, instead of branches. And second, it
depends on what type of DTML object you have this code in. Is this code in
a DTML Method or a DTML Document? If it is a Document, you'll have to
specify the Folder you want the tree to start at::

<!--#tree expr="PARENTS[0]" branches_expr="objectValues(['Folder', 'File'])"-->
  <!--#var id-->
<!--#/tree-->

I think that your approach would work and have the drawbacks you suggest.
You could try it and see if performance is actually a problem.

Here are some other ideas.

First, you can put an object in many folders without creating
multiple copies.  You can't do this from DTML, but you *can*
do it from Python, and therefore, from an external method. 
This may be the simplest approach.

Second, you could come up with some sort of document management
system, based on clever indexing machinery, like ZTables or
on relational databases.  As someone else mentioned, Zope cataloging
with use ZTables to provide collections with advanced searching and
organizaing features.  This is still a work in progress, however.

You're wrong. ;)  There are a numnber of ways to solve this.  I suspect
the simplest is to simply put the same object in multiple folders.

(BTW, this is essentially the same thing as using Unix hard links.)

Sorry you didn't get an answer.  There is no problem with creating 
acyclic or cyclic graph constructors in the, uh, object hierarchy, 
which BTW, need not be a hierarchy. :)

Yes, exactly.  In fact, a better name for aq_parent might

Hello!

   I've finished large project using pure CGI concept (I used Neale's
html.py). Now I (and my boss) are thinking of switching to Zope, or at
least ZTemplates.

   While playing with Zope and SQL (I am using Postgres, hence ZPygres
Database Adapter), I found that Zope, when loaded into memory by Zope.cgi
(I am using Apache, and need to use in the future) opens a database
connection for every Folder where I created Connection object.
   It is bad, as I have many databases, so Zope eats up memory. Another
problem - what would do Zope if I restart Postgres (so all current
connections break)? Would Zope reestablish connections or just report
error?
   How could I limit number of connections Zope opens? How could I
define a timeout, after which Zope close a connection if there is no
activity between Zope and Postgres? and reestablish connection when
application ask for SQL data?

   With ZTemplates and CGI all these questions has one easy (but not so
nice) answer - there is no constant connection, a connection established on
every CGI invocation.

PS. BTW, I wrote short introduction to Zope in Russian:
http://sun.med.ru/~phd/Russian/Zope/
   Any Russian here to verify my understanding of Zope?

As I understand it, you should just create one Connection object in your 
root folder.  Then all the folders underneath the root folder have access 
to that same Connection object.

Ahh, no need.  Just put one Database Connection object in the top folder
and all the subfolders will "acquire" it.  That is, any SQL Method
defined lower down can use it.

It should re-establish the connection.  If it doesn't then there's a
bug.  This works fine with all the Database Adapters I've used.

There is one connection per Database Connection object.

Hmm, this is quite a hard thing to do, unfortunately.

Of course this means the CPU gets a tremendous beating on every request
and the response time goes down.

   There are connections to different databases. So you said "one
connection to one database"?

   I'll retest, but currently, when I ask ZPygresDA to close connection,
Zope reports "the site has technical difficulties" when I'm trying to
access the application.

Not too long ago I experimented a little with cyclic structures
inside Zope's database. One thing I noticed was, that the copy
support failed with tracebacks like this:

Traceback (innermost last):
  File D:\Programme\zope\koelnzope\lib\python\ZPublisher\Publish.py,

This led me to the conclusion to better leave my hands
off non-hierarchic data structures which differ from those
created by the management interface itself.

More or less simple answers like "this is ok and this
is not", or "you can store any complex Python data
structure inside the DB, but in conjunction with the
management interface, you get the following drawbacks.."

I'm still a quite unclear about the object management
in the database itself and the management layer Zope
adds. 
But maybe I just have to read the docs harder ;-)

If you can use one connection string in Postgres to access multiple
databases, then you just need one Database Connection.  Otherwise,
you'll need one connection per database.  Note that I don't mean per
table -- I don't know much about Postgres and don't know if it organizes
tables into separate databases that are selected with a "use database"
command.

Right, which is the correct behavior, as you had disconnected from the
database.  I thought your question was about restarting _Zope_, so I had
a misunderstanding.

I don't know anything about the Postgres client library and whether it
can reconnect to a server when the server is shutdown.  This definately
isn't a Zope issue though -- the client should handle it.

   No. Connection string include database name, so I need one connection
for every database.

   I meant 3 different situations:

1. I started Potsgres, then started Zope, then restarted Zope - Zope
reestablished connections. It's Ok.

2. I started Potsgres, then started Zope, then restarted Postgres. Zope
does not reestablish connections: This site is currently experiencing
technical difficulties...

3. I started Potsgres, then started Zope, then went to management screen
and explicitly close a connection. Zope does not reestablish connections.

   Situations 2 an3 could be resolved, if I go to management screes, close
and reopen database connections. But it is hard to remember "always restart
Zope if you restart Postgres"...

I'll admit that cyclic data structures are pretty rare, 
so handling them may not be totally correct in every case.

Export of objects partcipating in cycles is potentially, 
uh, confusing, unless the cycles are with objects that are totally
contained within the object being exported, although containment
is pretty hard to check.  I should probably take this error check out.

OK, but I need to know what "this" is.  I don't think
you want me to enumerate all possible "this"s. ;)

> or "you can store any complex Python data
> structure inside the DB,

You can store any complex Python data in the DB subject to:

  - It must be picklable,

  - It must follow the persistence rules:
 
    - Root objects must be "persistent" meaning
      they subclass BoboPOS.Persistent (or implement
      an undocumented interface that BoboPOS.Persistent
      implements, sigh)

    - Subobjects of persistent objects must be "persistent" or
      they must be immutable, or be used immutably, as in:

         def add_member(self, member):
	      members=self.members

              # Oops, mutated a list
              members.append(member)

	      # OK, so pretend it's new and readd it
              self.members=members
         

> but in conjunction with the
> management interface, you get the following drawbacks.."

Basically, the objects need to implement certain
interfaces if they want to play in the management system.
If they don't want to play, they have alot of freedom.

We need to do a much better job of documenting these interfaces.
 
> I'm still a quite unclear about the object management
> in the database itself

The object management at the database level tries to be as 
transparent as possible.  The wish is that you don't have to
think about it.  Basically, if you follow the rules above, 
you should be OK.  

Probably the biggest pitfall in the database is the inability
to get to database objects when their classes can no longer be 
imported, because classes or modules have been moved or deleted
or because errors have been introducted into the module source.
We need to figure out ways to make these problems easier to
diagnose.

Maybe you just need to read my mind better. ;)

Ok, so we don't have a problem here :-)

I agree that if a remote cause forces a database connection to close, it
should attempt to re-open it... that should be optional of-course, but
should be the default.

Nope, you closed the connection, you have to open it.  This I agree is
the appropriate way to behave.

   May be...

   Well, what about such situation:

4. I started Potsgres, then started Zope, then worked with my application
and Postgres failed (postgres fails sometimes). Postgres returned an error
and closed connection. Zope, I think, should reopen the connection back,
but will it?

Well, actually it should be the job of the DA, not Zope.  It's not
spelled out in a standard anywhere, which probably should be solved.
More documentation probably :/  But hey, someone's gotta know what the
DA is really supposed to do, other than looking at an existing one.

Don't honestly know if it WILL, but it seems reasonable that it should
be capable of trying at the very least.  Again, this is the
responsibility fo the DA, not Zope... that should be made clear.  You're
using a 3rd party DA, so you might want to talk to them about it as
well.

So class Persistent's __setattr__ is basically also the level
that transaction and undo support work on? 
Can I expect the undo support to work if I take care of the
persistence rules, regardless of cyclic and acyclic structures?

Propably about time to switch to Zope-dev...

Pedro - 
If you need to do periodic tasks, the wisdom of the list says go with a
cron job script attaching to your Zopesite via the ZClient interfaces
(caveat: I know nothing about this - just repeating what I've read here)
Anyone know were to look for info on this elusive ZClient stuff?

Read the source luke :-)  

Actually here's where to find the basics of what you're interested in...

	.../lib/python/ZPublisher/Client.py

This should probably go into the FAQ in the ZDP PDQ ;-)  I remember
seeing a few examples of it, for the the life of me, I can't find them!

Subject: [Zope] Using database-connection from external methods
Message-ID: <19990323200153.C251@RaVER.duck.org>

Hi!

This will hopefulle be my last questions in a while...

Is there some way I can reach/use ZMySQL connection method from within an
external method? Rephrase - I have a connection established within Zope - I
want to call an external method that handles some sql-queries - is this
possible, or should I still have the external method handle it's own
connection?

Can external methods set/send back variables to the calling document/method?

Another question while I'm at it - is the DateTime module in 1.10.2 broke in
some way? (I get an error if I try to make a new property with the date type
set)

Help is much appreciated

The next release of Zope will have a 'utilities' directory
in the distribution that has a load_site.py utility that 
demonstrates use of ZClient (aka ZPublisher.Client).

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

After reading Jim's mail I turned myself to the cron. I had already
written a simple script to http-call a DTMLDocument that calls my
external method. It works, but now that you told me about ZClient I see
I could have saved some time with just a single command

ZClient.py [-u username:password] url [name=value ...]

Thanks guys

Connection strings for MySQL also require you to include the database, but
you can still change databases at runtime via the 'use <database>'
command.

Subject: [Zope] Zope Database in XML
Message-ID: <36F7EF09.6AD34A99@digicool.com>

A side project of mine is to allow conversion to and from
Zope databases (and export files) and XML.  This will allow
people to more easily access their data without Zope and correct
problems, such as moved or renamed software modules, that prevent
data from being unpicklable.

I've completed a first cut at a tool for converting a Zope 
database to XML format. It is provided in the file 'bbb.py'
in a 'utilities' directory that will be included in the 
distribution directory of the next Zope release.

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

To run the tool, use:

  python utilities/bbb.py -rxml var/Data.bbb

For now, the tool provides a way to "get at"
your data without Zope and get a bit more of an idea
of how Zope organizes data in the database.

The file uses a module 'ppml.py' (Python
pickle markup language :) that must by in the
same directory as bbb.py or in the Python path.
ppml.py provides for conversion from Python pickles
to XML.  It will eventually provide conversion
from XML to Python pickles.  Comments from members
of the XML SIG (those who happen to spend time here
too) would be welcome.  I haven't written a formal DTD
for this XML format.  I would like to use a standard Python
XML pickle format, but I'm not sure if such a thing exists 
yet.

I took the approach of conversion to and from Python pickle
format for two reasons:

  - It allows me to do conversion to and from
    database format without actually creating any 
    (application objects).  This is much faster than
    creating actual objects and does not require that
    any application Python modules needed to unpickle 
    objects be around or working.  For example, this allows
    conversion of objects that are not unpicklable.

  - It means that many of the implementation details
    of pickling can be avoided.

Of course, in combination with the Python pickle modules, 
pickling objects to XML is straightforward:

  import pickle, ppml
  print ppml.ToXMLloads(pickle.dumps(myobject))

Enjoy.

Just have your external method call ZSQLMethods. For instance, I have an
external method which allows the user to upload a file to the database.
The external method reads the file, parses it, and calls a ZSQLMethod to
update the database.

To do this, assuming your ZSQLMethod is in the acquisition heirarchy,
simply call it like you would any other method. If you have a ZSQLMethod
called 'insert_client', which takes the arguments 'name, company, email',
just call it...

self.insert_client(name=client_name,company=company_name,email=client_email)

 
> Can external methods set/send back variables to the calling document/method?

External methods can modify the current REQUEST object that the DTML uses
from name resolution. If you are calling the external method from within
the DTML, just use 'self.REQUEST' to access the current REQUEST object.
Just create/set items on it like it was a dictionary... 

sekf.REQUEST['new_key'] = new_value

If you can access the database directly through this interface(xml/pickle),
couldn't you *potentially* map a network drive to the interface(cifs/nfs).
This could allow you to render data in and out of the database through the
file system interface rather than ftp/http.

Just a thought!

Alternatively your external method can return objects to the calling DTML.
for an external method spammethod you could do omething like:

class A:
	pass


def spammethod(self,n):
	a=[]
	for i in range(n):
		tmp=A()
		tmp.no=i
		a.append(tmp)
	return a

Then in your DTML you can do something like

<!--# in "spammethod(20)" sort=no -->
<!--# var no -->
<!--#/in-->

I'm not sure what you are getting at here.  You can export and import data to
a file system now, using the Zope database format, which is built on
Python's pickle format.  The XML conversion feature just gets the data into a
slightly more editable form.

One key difference between http/ftp and the file system is that
Zope trusts the file system much more and is willing to get pickles
(binary, XML, whatever) from it.  This is a sort of a security 
feature.  In the future, I'd like to make a variation on the
Python pickler that was easier to configure to be pickier and
safer to use with network supplied pickles.

Ok, I figured out a way to hack around this limitation of traversing an
ZSQLMethod. I whipped up a simple 'pluggable brain' for the ZSQLMethod in
question...

---------------------------------------------------
from Acquisition import Implicit
from Record import Record

class req_store_brain(Implicit):
    """ stores info from sql query in REQUEST """

    def __init__(self):
        new = {}
        for key in self.__record_schema__.keys():
            new[key] = getattr(self,key)
        self.aq_parent.REQUEST.other.update(new)
----------------------------------------------------

This simply sticks the results of the ZSQLMethod in the REQUEST object.
Everything in the heirarchy after this has access to the queries results.

What I am referring to is rendering objects in the ZOPE database to a file
system view. The object database could be managed as a Network Drive(except
that the view would be data in the ZOPE object database). You could through
some translation (xml or other) render the object database to CIFS/NFS.

1. Run applications directly from the ZOPE file system.
2. Modify and Render objects through a regular file explorer or file manager
potentially an external text editor or file editor(word,excel,other).
3. Objects that had no meaning to the file system view would not be
rendered. Attributes to file properties.

This is a feature of 8i that oracle is pushing. The rendering of a database
to a user that does not realize it is a database.

ie.
1. Open a spreadsheet in the Network Drive and see a current version of a
file and its data.
2. Intranet is now a shared drive - depending on your privileges - you see
different objects.

I guess what I am asking is: Can Zope act like a CIFS/NFS file
system(virtual file system) with a layer of translation for converting Zope
Objects to File system objects directly (XML or other)?

If I understand it, this is how the database is rendering objects to HTTP or
now(Zserver)FTP. Why can't you render them as a Network file system?

Any thought?

Zope trusts the file system much more and is willing to get pickles
(binary, XML, whatever) from it.  This is a sort of a security 
feature.  In the future, I'd like to make a variation on the
Python pickler that was easier to configure to be pickier and
safer to use with network supplied pickles.

I've just hit something similar in the mysql client. The mysql client
has a time-out to close the connection with the server. I'm using it in
a test environment where it isn't accessed frequently. The connection is
automatically closed and I have to manually close and open the database
connection.

Has anyone already fixed it? Excuse me if it has already been asked in
the list, but the egroups site isn't working.

You seem to be asking for a hybrid of Zope and Samba ;-)  Seriously, we
have Samba, so one answer would be a filesystem driver for the undelying
OS that talks to the Zope server to get its information. This could be
re-exported as a samba share, or NFS or AFS or Coda or what-have-you. 
I've been musing about it for linux for a little bit - I'm going to try
and convince one of the bright sparks around here to take a crack at it.
For NT hosted Zope, you'd need to write an equivalent filesystem driver
- apparently the the SDK for that is ~$1000.

Oh, and parts of this are already present in the ZServer - it talks FTP,
and there was some discussion of exposing object properties as virtual
docs of some sort. Check the list archives.

Ah.  I think that this is one of the things that WebDAV is going to
accomplish.  For example, IE5 can create an thing that looks like

Message-ID: <57D47461794DD211825300A0C9D17EF906C8CB@IGOPDC01>

Ahhhh....

Oracle's approach to this is an add-on to 8i called IFS(Internet File
System). It renders a database to http(woo...woo, Zope does this in its
native functionality). Although, they are working on a renderer for native
file systems. This would enable object methods for making files on the fly.

As Zope already accomplishes this(rendering objects), thus presenting the
view of the oo database is thus a filter. HTTP,FTP,CIFS,NFS,POP,IMAP all are
protocols that speak the requesting clients language. Make Zope the engine
and supply a framework in Zserver to plug in the server renderer.

Samba is a great example. It renders between file systems quite well,
although it is rather a tough and complex animal and very specialized.
Although it would work along the same lines.

Actually, there is a PERL module to simulate file systems already. It could
be good start. Considering that most file viewing on Windows is moving to
HTML, the Network Drive is looking more and more like a simple security
login with a connection that is persistent, rather than actually mapping the
drive.

A distributed (native-CIFS/NFS) file system would change the industry.
Actually it already has (http) through a browser window. I am wondering when
it will occur as seamlessly as not having to be in a browser. If an ORB
existed that could render data to the requesting protocol, it would be a
great product, I think ZOPE could do this through the ZServer architecture.

The Server in this case is the renderer, the ORB is the fulfillment
component and the OO Database is the storage mechanism. The protocol plug-in
is stored in Zserver and renders the appropriate view of the data.

 PROTOCOL |    SERVER    |   ORB   |  OO DATABASE  |

</OS ADD-ON CLIENT> 
   HTTP   |    ZSERVER   |    --- ZOPE ---         |     Client dependencies
   FTP    |    ZSERVER   |    --- ZOPE ---         |     Applications
designed to be client/server!!!

   IMAP   |    ZSERVER   |    --- ZOPE ---         |
   POP    |    ZSERVER   |    --- ZOPE ---         |
</OS ADD-ON CLIENT> 

<OS NATIVE>   
   CIFS   |    ZSERVER   |    --- ZOPE ---         |     No Client
dependencies - Native Applications
   NFS    |    ZSERVER   |    --- ZOPE ---         |     CLIENT/SERVER
functionality yet no dependencies!
</OS NATIVE>                                             OS support is the
dependency!

If the rendering engine were modular, ZOPE would always be first in
delivering support for new protocols and client functionality(DAV
Support!!!), without changing the structure of the underlying database. The
data exchange between the ZSERVER AND ZOPE would have to be managed. "You
wouldn't want to serve a POP client an Excel file unless it is an attachment
just as you wouldn't want to render a query to a FILE SYSTEM accept ones
that have been designated as OK." Get It?

It would save the world a little time and effort if one system could render
data to a diverse set of clients. Rather than making a new server every time
a new client arrives. I could simply build a layer of translation(XML) for a
client and BINGO! New client/server.

At the Native OS level this has the most power. Rendering live data into an
Excel file on the fly is a real world application that would be a huge hit
right now. "I want this months sales report... open Sales.xls  BINGO!!! The
data is there." I would really like to edit html in Dreamweaver as I
regularly do and have it render into Zope. If you had file system level
support every known application could be stored inside of Zope or have
access to the data inside of ZOPE.

Here is the interesting one:

If you can have direct file access you could:

Open a client application out of an oo database that rendered a view of the
database back at you.

(Sounds awfully like an OS!!!)

Just Thoughts.....

[Project Idea] Looking ahead to the future of Linux ...

[ I am on the Digest list, so send responses directly if you
  expect an immediate response. ]

Although I am a new user, I am quickly growing very fond of Zope.  Quite
amazing, multiplatform and all.  The option to use either the built-in DB or
an external one, the built-in web server or an external one.  My entire
company is thinking of standardizing on Zope since we run Solaris, Linux and
NT (along with a few, rogue *BSD variants) on our server-end.

Little and big internal projects aside, I was wondering if Zope could
possibly fill a gap that will come about with Linux shortly.  That gap is
software distribution at the enterprise server to client level.

Linux (and many other OpenSource software and systems) is winning in the
server arena, but the corporate desktop world is staying with NT and the
consumer world is staying 95/98.  While the third will take awhile, the
corporate desktop is something that is attainable in the next few years
(with all the Windows 2000 issues which I do not want to get into).
Microsoft has SMS for NT and even Apple has a better system for MacOS X
Server.  What does Linux have?

First off, most Linux distributions have RPM.  While the format is the same,
the filesystem and other distribution or installation-specific configuration
may differ.  Quite possibly, a Zope-based distributed management system
could be built to serve this purpose.

I guess my main question is if anyone else is trying to forge such a project
togther.  E.g., does the Caldera Open Administriative System (COAS) plan to
solve such software distribution issues?  If not, do any others?  If not,
I'd say it is a BIG DEAL to get such a project underway.  And Zope may be
the perfect fit for the back-end (hence, why I am posting this to this list
instead of a my local LUG).

Just an idea.  Please feel free to pick it apart (short of calling me an
idiot, well maybe you should anyway :-).  I am still learning Python at this
stage (big-time Perl advocate, but Python is definately better for
web-apps).

The field of online software distribution is certainly hot.  Marimba,
the original Java darling, has reinvented themselves in this field:

  http://www.marimba.com/products/products.htm

They are playing, though, in a pretty complicated mission-critical kind
of field.  The requirements are pretty daunting.

One thing I've seen that's pretty interesting in a low-tech kind of way
is rpmfind from rufus.w3.org from a repository.

It's certainly a big deal in that it is an enormous initiative.  Take
some time to jot down what you think the business goals and the
requirements of such a project might be and recruit some volunteers!

Beyond writing an ExternalMethod, is there a good way to catch exceptions?

For example, I have a database application that looks pretty ugly if

a <!--#try--><!--#/try--> tag to trap exceptions and to provide handlers

Anyone have any thoughts on this?

Message-ID: <8174B1EE3D2CD21180960000F8056723FCC3CE@telisnt1020.is.tel.co.jp>

 Thanks for the pointer!

 I have to retract what I said in a previous post about not having a
 problem with the ZODBCDA--it has the same problem. I had made a small
 hack of a product for my own study that connected through ODBC and
 that didn't have the problem because I used Python longs. I somehow
 got the two confused...

 This works, but everything gets converted to floats like you said. In
 my case, this is not so much a problem because I use a lot of large
 numbers but doesn't seem practical for general use.
 I found that if, in Buffer.c, I change lines 143 and 144 to

      case 'd':
         return PyLong_FromDouble(self->val.d[ii]);

 I can get the same results as my product--everything is a
 long. Unfortunately, this causes everything to be printed with
 Python's 'L' appended instead of '.0'. Either can be fixed by
 using fmt="%.f" to all of my number fields, but that seems like a 
 lot of extra work (maybe a quick hack to the Z Search Interface
 would do the trick?)

 Plus, what if I really have floats somewhere? Would something like:

      elif dbtype==2: # Number
         if scale:
            buf=Buffer(arraysize,'f')
            dbtype=4
            dbsize=8
         else:
            buf=Buffer(arraysize,'d')
            dbtype=4
            dbsize=8

 in ociCurs.py (lines 123-131) handle this? I haven't tested it yet on
 float fields. It might be better to just leave everything as floats.

I'm not sure I understand what you want here, but perhaps interesting
for you is the Trove project. Perhaps it's directed more to larger scale
internet based distribution, though. Another problem is that as far as I
know the project isn't progressing very quickly if at all (perhaps you
can help).

I've even heard mention of ZTrove, which would be a Zope based Trove, if
I understand well. I don't know what the status on that is.

Mind, I don't know a thing about Trove, just giving pointers in the hope
it's useful.

Trove is sketches of code in Python (written by Eric Raymond) and ZTrove
is vaporware, barely prototyped in bobo a few months ago when I was on
the Trove list.  It's unfortunate, since I felt that Trove was a great
idea; the Internet hasn't reached the point of 'we need it now' in order
to get some development behind it.  Personally, I think Sunsite and
RedHat should give us lots of money so we can write it. :)

With Ken and I now in the Zope loop (Ken was one of the original Trove
designers, and I was in on the GUI side of things, pushing what was at
the time Bobo) we could probably bang something out sometime in the far
future.  We'd prefer someone in the community start it up because Paul
and Rob have us booked sometime into the year 2011.

I just ran into some odd behavior with fsimport that may explain the 
problem that Milos posted last week.

On my Linux box, if fsdir == '/fred/barney', then fred as well as 
barney must be world-readable. If not, you get the error traceback 
Milos reported in his March 14 posting.

Oops, posted too fast. I should have said that fred must be world-

Confera uses ZTables functions, and these were introduced in Zope 1.10

...just download Zope 1.10.2 and Confera will work just fine.

Confera requires Zope 1.10.2 to run. SearchIndex is a package that is
oncluded in that release.

Zopists,
    I have a secure site and trying to secure a part of the site so that
only those with the role of system admin coulds access.
One special page has the following code the uses a 'with' tag to include
a parent environment:

<!--#var standard_html_header-->
<H2><!--#var document_title--></H2>
<P>
<b>Available Documents:</b><p>
<table border=1>
<!--#with gestalt -->
<!--#in displaylinks -->

<tr>
 <td><a href="<!--#var protocol-->://<!--#var host--><!--#var
path-->/<!--#var name-->"><!--#var title--></a></td>
 </tr>
 <!--#/in-->
<!--#/with--></P>
</table>
<!--#var standard_html_footer-->

The parent object has the following permission settings:
Roles
 Acquire
 permission
settings?                 Anonymous      Manager  Sysadmin  User

 no         View                                    yes

no   use SQL methods

the rest are set to acquire .... the role sysadmin is declared in the
gestalt object..

Do you what am I doing wrong?

That's just Unix-style permissions, no?  Can't expect to

Subject: [Zope] Counters
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC6F@peter.sths.org>

I remember noticing various comments on the list bemoaning the lack of
some sort of counter. I also remember noticing the objections which were
raised, and why counters weren't feasible. I don't remember reading
these objections, which may be why when I found a need for a counter, I
sat down and wrote one. I now have a working Counter product which
provides a <!--#counter--><!--#/counter--> tag .

It includes the ability to have multiple non-incrementing displays of a
counter, and the optional ability to render the individual digits using
a supplied template, thus allowing graphical counters of whatever sort
you feel like using. The counter uses a long property in the containing
folder, so you can manually set the counter to whatever you want. 

It also provides the optional capacity to have a short 'memory' of
recent IP's, preventing the 'running up' of the counter by scripts or
massive reloading (well, makes it more difficult anyhow). 

The template is supplied with variables which indicate the position of a
given digit in the list (it is wierd, it works from back to front, since
it uses modulus) including whether the particular digit is the first,
etc. 

If someone will supply me with instructions on how to package the
product, and how to upload it, I will be happy to make it available.

Thanks are due to tsarna@endicor.com, on whose product this was based,
and to Jim Fulton and Philip Aylesworth for answering my questions.

Uh, no, I think. chown root /fred, chmod 700 /fred, chmod 711 
/fred/barney. Then anybody can get a listing of barney, but only 
root can see what's in fred. And if I su nobody and run python, 
os.listdir('/fred/barney') works but os.listdir('/fred') gets 'Permission 
Denied'.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC71@peter.sths.org>

With regard to the IP checking mechanism. Realize that this reduces the
count for machines behind a masquerading firewall and increases the
count for machines on dynamic IP dialup accounts. 

If anyone is interested in using this counter but wants to prevent a
given IP from incrementing the counter a second time under any
circumstances, it should not be too hard to modify the code to store the
IPs in an SQL table as (I think) Slashdot does. I have no need for this,
and don't intend to code it, but the code, being Python, is, I think,
clear enough to modify.

Hello,

I'm trying to put together an External Method that needs to operate

How do I specify an object ID and retrieve the relevant object? sorry 
to be obtuse, but I can't find an example anyplace. In the onl;ine

I'll indicate my appreciation of your contribution by, well, asking for
more! :^)

One of the big objections of the counter kind of object is that the
object database gets bigger on every request.  A good workaround for
this would be to cache writes to the database.

Thus, imagine a counter that:

1) Only wrote to the database after a threshold had passed.  For
instance, only every tenth state change or not until ten minutes had
elapsed since the last write.

2) If the process was nicely shut down, the object would save itself.

3) Had knobs in the management screen that allowed adjusting the
"buffered write" policy.

The benefits:

1) The database wouldn't keep versioning into oblivion.

2) The application wouldn't be slowed by writes on every request.

The drawbacks:

1) If the process exited not nicely, some state changes would be lost.

Subject: [Zope] Longs on the Property page
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC72@peter.sths.org>

In the stock Zope 1.10.2 distro, putting a Long in a property causes a
curious error to manifest. When the property page is displayed, the long
is display like 44353L. If the then change any other property and
attempt to save changes, you get a traceback saying that the property
for the long is invalid. You are forced to manually remove the 'L'
before saving changes. 

May I suggest that when the properties are display, if the type is
'long' then the display code
should do something like this:
str(long_value)[:-1]

This would remove the L before it was ever displayed.... Alternatively,
something in the response code needs to be modified to accept an 'L' at
the end of an integer destined for a property whose type is 'L'.

Subject: [Zope] The best way to pack and close PickleDictionary?
Message-ID: <19990324200904.8613.rocketmail@web204.mail.yahoo.com>

Previously, using Bobo, I created several PickleDictionaries for use on
my website. Regularly, I would pack these databases before ending the
CGI call since they were altered very frequently.

Now, using Zope, I find that I cannot pack them without receiving error
messages telling me I'm attempting to write while the database is in
read-only mode (it appears the Zope threads out the packing). I also
found that Zope caches these databases and issues an error when I
attempt to open them again.

What is the best way to pack and close these databases? How can I query
which db's have been opened? Even if I do keep a mapping of previously
opened db's, how can I find out if Zope is closing them. 

Any help is appreciated. 

Thanks,
Kevin

Hey.. this isn't bad.. in writing even :)

Okay, I have a prototype of this written.. basically you can do the
following:

<!--#try-->
foo
bnar
<!--#var sgkjgdsjksdg-->

<!--#except-->

The exception was <!--#var err-->

<!--#/try-->

So, if an error occurs inside the first block, the second block is
rendered with err substituted for the variable (in this case it prints
exceptions.KeyError

This is pretty basic stuff, so I'm looking for ideas on where to take
this.

Anyone have more ideas?

This is just a guess, but I doubt it.  You'd probably need a DOS port of
Python, which would eliminate all the networking code.  This is just me,
I don't have a 3.1 box, but... you're welcome to try :-)

Message-ID: <613145F79272D211914B0020AFF640190D9F66@gandalf.digicool.com>

I've gotten a lot of reports about a broken link to the ephemeral,
much-referenced "BoboPOS3a1" technical docs.  I promised myself I
wouldn't update the link unless I updated Jim's doc to Zope-ify it.

Thus:

1) The official name of the database is "ZODB", the Z Object Database.

2) The News on the site has a link to the ZODB3 Technical Documentation.
This is a very well written, circa October document from Jim Fulton that
describes the architecture of the next version of the database (i.e.
Zope2).  It's quite nice -- contains UML diagrams, API discussions, etc.

3) The broken links have been updated.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC79@peter.sths.org>

Ok, having read the newly available ZODB manual, it seems that I should
override __setstate__ and call the old __setstate__, passing it a
dictionary containing only those attributes I wish to be persistent.
Then I don't have to call my __setstate__... it will be called
automatically by the system. This should have the effect of making any
item not mentioned in my dictionary non-persistent, which will allow me
to accomplish Paul's goal. Now, the BIG question... This ZODB manual is
for ZODB3, which we don't yet have! So is this still the correct and
workable technique for accomplishing this?

Thanks again... and please everyone, don't use the old Counter product,
since these tags are going to conflict horribly, and this new product
should be much better for the DB, according to Paul, if I can make it
work.

For .deb there is the official package manager (www.debian.org), but
there's a 'Debian Package Finder', which is already complete python :-)
On http://badger.alaska.net/debian/finder.cgi
That may be easier to convert to Zope.

Well - darn if you aren't right.  Only the

Here is the updated Counter Product. This contains two classes, one
which provides a visible Counter Product which can be added as an
object, and which has Security options, and a new tag which provides a
means of accessing the Counter Product. Note: the tag should be able to
access ANY object which possesses a getCount() and a incrementCount(md)
where md==_. So an SQLCounter Product which stores its numbers in an SQL
database should be able to use the same tag structure. Since it passes
md into the incrementCount, the Product is free to store as much or as
little of the REQUEST as it chooses. My product stores only the IP
address, and only under proper conditions.

The tag structure is described in the CounterTag.py source file, and
examples are given.

I hope this is useful to someone.

Okay after I opened my big mouth I had to deliver. :)

NOTE: THIS IS NOT ALPHA ALPHA CODE.. BEWARE

Here's an example of what this is:

<!--#try-->
 This is the try block
 <!--#raise type="bar"-->
  You suck
 <!--#/raise-->
<!--#except-->
 There was an exception! Yay!
 <p>It was <!--#var errname-->
 <p>It has this to say: <!--#var errmsg-->
<!--#/try-->

I incorporated a suggestion that except should handle <!--#except
NameError--> to specify the error to trap.  Also, <!--#except--> will
handle any errors by default.

This is packaged as a product, is this the best way to distribute this??

Grab it from:
ftp://ftp.spyderlab.com:/pub/zope/Try-0.1.0.tar.gz

Since I've only been programming Python on and off, hopefully I didn't
make any major assumptions about doing things a certain way.  Please let
me know if I have.

There is another IRC channel on the EFNET network, #zope.

It is 'protected' by an eggdrop bot so there should be little chance of the
channel disappearing.

It is manned, at the moment at least by, Phil Harris, Fredy Villa and
others.

There is also a knowledge bot, zoppy, which can answer rudimentary questions
about Zope/Apache/Python.

We have a small but growing community, join us.

See ya there

If I have a URL like '/manny/moe/jack', I know that from within the 
top-level object, I can retrieve the object 'jack' as 'manny.moe.jack'.

But if the context is jack, how do I specify the top level so I can 
talk about manny?

Hello,
I want to use a computed field to convert the broken umlauts from a

translate(ARTBEZ,maketrans('”�„','öüä'))

But when i test the expression i get the following result:

Test Computed Field
Expression: translate(ARTBEZ,maketrans('”�„','öüä'))
Computed Field Error: (, )

Does anybody have a solution for my problem?

The top-level object is the 'app' attribute in the Main
module.  Note, however, that this will change in
ZODB3.

  import Main
  Main.app.manny

From an external method, self is the object the Externel Method is called
from. If you have REQUEST passed in, you can access PARENTS[0], which is
the top object. From there you can traverse down the hierarchy.

Message-ID: <Pine.GSO.4.02.9903250839420.15119-100000@isis.visi.com>

Okay, I understand that the "fall-through" authentication to Zope will not
work with rewrite rules when Apache 1.2.6 is used.  Unfortunately the
project I'm starting is being done for a shop that refuses to upgrade to
1.2.6.

I have Zope working just fine with Apache authentication; for the needs of
my project, this method of authentication works just fine.  However, I
need to know how to properly set up Zope to run in a virtual domain
"container", _and_ to only authenticate parts of the object hierarchy at
one time.

The idea is that we have a website

docs.foobar.net

that is a virtual domain on an Apache 1.2.6 server, and we need to
authenticate any requests underneath

docs.foobar.net/manage

so that the world can see the pages but only people in our list can
manage.

Another simultaneous difficulty is finding the proper way to make this
virtual domain automatically start in folder "docs" of Zope's object
hierarchy.  I've used an Alias to translate docs.foobar.net to
docs.foobar.net/cgi-bin/Zope.cgi/docs , and it works fine, but I don't
have proper Zen mystical knowledge of Zope to understand the _proper_ ways
of doing these things, if such ways exist.

I have done a scan of Email archives and most of the documentation on the
Zope site, but either I'm dumb as nails or just don't know the proper
magic keywords to get the information I need.

Zope looks great, I've resisted learning a new language but a killer app
makes it worthwhile.

Cool.. it still needs a bit of tweaking before getting integrated.  I'd

I am not sure how to classify it. The original complaint was about the
Properties page. 

My problem seems to be with values returned from MySQL - even regular
integers get an L tacked on the end (This didn't happen with zope 1.9).

So is this two seperate collector entries?

Where does mine go - Zope, ZSQL Methods, or ZMySQLDA? What do others
think? Has this shown up with other SQL DBMSes?

One thing I just thought of: I moved my ZMySQLDA over from 1.9 to 1.10.2
without recompiling it. That is when I noticed this problem. Whould
something have  changed in the python header files or something that
would have made it advisable to recompile ZMySQLDA? What did others do?

Phil.

Subject: [Zope] The Artist Formerly Known as NotMail
Message-ID: <613145F79272D211914B0020AFF6401907BBB6@gandalf.digicool.com>

Greetings,

For those of you interested in the NotMail project we have some
announcements.

First, Digital Creations has officialy adopted NotMail as one of it's
products.

Second, in an attempt to make the products at least *sound* more mature
:), we are changing the name.

Third, in the last two weeks I have been working pretty hevily on
NotMail and it has changed significantly.

Therefore:

NotMail is, for the interum, called The Artist Formerly Known as NotMail
(TAFKAN).  We still call it NotMail, but that's just our code word.

TAFKAN was once a product, but now it's just a bunch of dtml methods.
The actuall imap functionality that TAFKAN needs has been abstracted
into another product called IMAPAdapter.

IMAPAdapter is very early alpha software.  It has several known bugs,
and Linus knows how many unknown ones.  Your millage may vary.  It may
light your computer on fire.  It might delete all your mail and crash
your imap server.  It might send insults in your general direction.  You
get the point.

IMAPAdapter is, in Zopespeak, a 'user database'.  Other examples of user
databases are User Folder, UserDb Folders, and etcUserFolders.
IMAPAdapter walks, swims, and quacks (to quote Jim) like any other type
of user database.  The simplest example of using IMAPAdapter is:

Create an empty folder without an 'acl_users'

Add an IMAPAdapter (it will automagicly call itself 'acl_users'),
telling it where to find it's imap server, what default roles to assign
to users, and other misc stuff.

Create a DTML Method called index_html containing the following DTML:

    <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

Going to this file will prompt you for a username and password (assuming
you've correctly set the permissions and roles).  The username and
password you enter here must be a valid IMAP login for your imap server.
It is *not* necessary to add a Zope user to Zope, IMAPAdapter will try
your uid:pwd pair against the IMAP server and validate/deny you based on
the sucess or failure of making an IMAP connection.

What you will see when you look at this DTML Method is a pretty #tree
breakdown of all your imap namespaces, folders and subfolders.

IMAPAdapter, like all other user databases, contains a validate() method
that Zope calls to authenticate a user.  This method returns an imapUser
object (which inherits BasicUser, like most other Zope user objects).
This user object is what AUTHENTICATED_USER refers to.  imapUser exposes
the imap API to the DTML programmer.  The API is currently a very rough
draft, and there are several functions that were in TAFKAN that are
missing in IMAPAdapter (like the folder management stuff to
add/edit/delete imap folders)  At the moment, IMAPAdapter is pretty much
read-only on your 'imap space'.

Voila!

IMAPAdapter is available in public CVS.

Web CVS access will be here soon!  (yippee!)

I have a Zope sandbox which I would like to use to play with new features 
as they become available.   Unfortunately, for the past several days my 
sandbox server has been broken because ExtensionClass/ComputedAttribute.c 
is missing.

Is it missing on purpose?  If so, is there  a way I can work around it?

Message-ID: <Pine.LNX.3.96.990325153317.2349F-100000@taos.kavi.com>

Hello,

I'm having a strange problem with logged in users getting to anonymous
areas of the site. Here's an simplified example to explain...

Two directories off the /
/private
/public

/private allows no access to "Anonymous User", requiring a login.

There are no usernames in /acl_users. All the user info for logging into
/private is kept in /private/acl_users. 

/public has no acl_users folder.

If you start up netscape, you can get to /public without any problems. But
once you've logged into /private, you can't get back to /public without
getting an unauthorized error...

  You are not authorized to access this resource. Username and password
  are not correct. 

  Traceback (innermost last):
    File lib/python/ZPublisher/Publish.py, line 877, in publish_module
    File lib/python/ZPublisher/Publish.py, line 531, in publish
      (Info: /MCExam)
    File lib/python/ZPublisher/Publish.py, line 297, in unauthorized
  Unauthorized: (see above)

Any tips about how to fix this. Note that the login info has to stay in
/private/acl_users (they can't be moved to /acl_users).

Thanks,

Ok, the problem was that I had the roles defined on the top level folder
and the users defined in the subfolder. By moving the roles into the
subfolder, the problem went away.

Thanks.  Yes, please go ahead and use this in the standard distribution

I suspect a matter of resolving.  Probably be a two step procedure, 1) try
to match the error by string exactly, otherwise 2) evaluate each handler 
in turn and see if the exception isa class.

I have fixed this in 0.1.1 of the Product which is now available from the
same directory as the original.  I've also made some other additional
fixes relating to the default error handler.

Here's the file:

Subject: [Zope] URL and #tree trouble...
Message-ID: <19990326081646.A10042@box.dust.za.net>

Hi!

A day or two since last question - now two new ones...

Q1

My site is organized so that one folder keeps several other files and folders (containing files and folders and so on). Something like:

Top [Folder]
	F1 [Folder]
	F2 [Folder]
		F2-file1
		F2-file2
		F2-folder1 [Folder]
		F2-folder2 [Folder]
			F2-folder2-file

...

index_html (Top) has <A HREF="F2">F2</A>
index_html (F2) has <A HREF="F2-folder1">F21</A> and <A HREF="Top">Top</A>

Starting at URL: localhost/Top is fine and following links to F2 and from there on to F2-folder is correct (URL beeing localhost/Tope/F2/F2-folder1), but if I, when in F2, press the link to 'Top' something strange? happens: I get to Top all rigth, but the URL is now localhost/Top/F2/Top (Top beeing appended to the URL)

What am I dooing wrong?

Q2

Recently I got help on using the #tree tag, and apparantly everything worked all rigth, but ...

I get the tree-view, can expand the tree pressing either foldernames or the '+' button - fine. But If I press the '+' button I'm not able top directly access the files appearing (404 error, file not found), I have to enter the folder first before I can get the file. This seems strange and I want to know if theres a solution to this.

Heres my #tree href part:

<A HREF="<!--#var URL1-->/<!--#var id-->"><!--#var id--></A>

Help is much appreciated

You're URL is a relative one. The browser sees 'Top', and requests the
object Top with the current Base URL, which is localhost/Top/F2/. And
because of Aquisition, Top.F2.Top exists.... And so will
Top.F2.Top.F2.Top.F2.... which can get you into a nice caching problem.

Your URL should include the realitve path to the subfolder. the var
tree-item-url gives you the URL to the current object, relative to the base
object.

Your code should read (untested):
<A HREF="<!--#var URL1-->/<!--#var tree-item-url-->"><!--#var id--></A>

Or words to that effect..

Computed attribute is not an includeable library, or something along those
lines 8^).

Hello.

   Continuing the subject...
   Next question. If Zope opens one connection to a database, how does Zope
manage concurrency?
   Currently, when two CGIs run in parallel, every CGI opens its own
connection to the database, lock neccessary tables, and Postgres manage
concurrency very good (even detecting deadlocks). Next Postgres version
(6,5) will have Multi-version Concurrency Control. But all this is for
different sessions. Zope opens only one session. Is it a problem with
concurrency?

Hi,

This is (I think) an unusual question on this thread, but I want to ask it.

We are at the start of making an intranet, which will contain a database of
procedures (how to handle some examinations etc). We want to make it able
that people can query this database and get the information they want on
there web-browser.

A day ago, we were confinced that PostgresSql with PHP3 (www.PHP3.org)
would be the solution to this problem. This on a RedHat Linux 5.2 system
with Apache as
web-server. But now we've seen Zope. I'm wondering..., can Zope do the same
things as PHP3? Or is this a complete different application? How stand Zope
and PHP3 next to each other?

I believe PHP3 is a scripting language... I'm wondering : is Zope also only
a scripting language? Or is it more? Is the scripting language (=Python?)
more powerfull then Zope)

Are there people, using PHP3 next to Zope? 

ps. Has Zope the capability to easely make these scripts? I mean not
text-based , but in a certain IDE or RAD application?

Please, say in some simple words what Zope is and for what it can be
used... I've read the web-page. But since I'm a stupid person in this field
of webservers I can't understand what they are explaining.

Thanks in advance.

Kind regards, Tom.

Subject: [Zope] Limitations of just using External Methods ?
Message-ID: <3.0.5.32.19990326185538.0093de20@mail.skinnyhippo.com>

Hi zoppelgangers,

I have several applications built 100% with python CGI
scripts that I'd like to run on Zope. The reason for 
this are :
a) For the better performance (I was worried about
   the scalability of CGI for high-availability and
   knew I had to move to FastCGI or the equivalent)
b) I really really like the way Zope takes care of
   the CGI variable handling (ie. declaring the 
   HTML form fields as arguments in the python method).

However, I don't really want to use DTML at all.
The reasons is that I find it much harder to read 
than pure Python. This is just a personal aesthetic 
thing and no criticism of Zope at all (full kudos to
Digicool on an excellent application). It's just
coding aesthetic : I like it all kept in Python, 
like servlets in java (as opposed to CFML, ASP etc).

So, I've put all of my CGI scripts in a newly-created
extensions directory and registered them via the 
Zope web-manager. It was, as the documentation says,
incredibly simple and it seems to work for simple
methods. (I'll declare my own packages later).

Now, if I just use External Methods like this (using my
own ex-CGI Python scripts to query databases, IMAP etc),
am I missing out on any of Zope's main benefits ? 
In particular, the cache management ?  
Would I have to turn my stuff into  a Zope Product to 
get these benefits ? (I've not had too much joy with
the Product stuff yet)

Message-ID: <000501be777e$83130900$147800a0@pc-pi0>

Hello,

I'm confused with external methods. Please help.

I want an external method to access its context (for the
purpose of acquisition, etc.). So I write:

def myExtMethod(self):
    pass

Within myExtMethod, I should be able to:
- write self.REQUEST to access the current REQUEST object (I
need to be able to modify the current REQUEST object with
self.REQUEST.set(...))
- or for example self.myzsqlmethod() to call a zsql method object,
right???

Let's suppose that myExtMethod is:

def myExtMethod(self):
    l=[]
    for i in self.l:
        l.append(i+1)
    self.REQUEST.set('l', l)

Now, how can I call this method from DTML?

<!--#var myExtMethod-->
<!--#var "myExtMethod()"-->
<!--#var "myExtMethod(this())"-->

All don't work. I end up in a traceback. "read only class, buffer"

Any hints?

Zope manages concurrency by being single-threaded... so only one query at a
time, on ANY connection...

   What about ZServer? It will be single-threaded too? Isn't it possible to
run Zope multithreaded?

Message-ID: <01E40461E003D21195CC0080296495D80B12F7@gates.cdc-group.com>

Hi Jepthe,
First, if you want to acces the REQUEST object, you need 
to declare it as a formal parameter:

def myExtMethod(self, REQUEST): ...

REQUEST is then passed automatically by Zope's internal
magic, which looks up formal parameter names and matches
them to arguments from HTML forms, HTTP Headers, etc.

The "read only class, buffer" traceback is due to a very 
annoying bug in ExternalMethod.py and screws up any 
other error messages in external methods.

I can't remember exactly if it was in line 254 or 256 in
ExternalMethod.py, but here's the code I use to fix it:

ExternalMethod.py, from line 254

                if type(error_type) is type('') and lower(error_type) in
('redirect',):
                    raise error_type, error_value, tb
                if (type(error_value) is type('') and
                    regex.search('[a-zA-Z]>', error_value) > 0):
                    error_message=error_value
                else:
                    error_message=''

With that you should get better error messages.

Regards,
Stefan

PS:
	<!--#var myExtMethod-->
	<!--#var "myExtMethod()"-->
should be both OK

Tom,

There are probably other guys here that can give you a better comparison
between zope and php3. I never used php3 but I used ASP (the microsoft
stuff), which is similar (though worst than php3 :-).

With Zope you get a server markup language (called DTML) which you can
mix with HTML. This concept makes it even easier to program than mixing
a scripting language with HTML like php3 and asp do. From what you said
I guess you will just need this kind of programming... so Zope will be a
better choice than php3.

But with Zope you also get *the best* scripting language available:
Python. You can add logic to your application by writing external
methods or products. This kind of extension is much more powerful than
php3, although maybe a bit more complex.

Zope also has a great IDE for managing your site through the web. 

Although I cannot tell you which one is better, if you give Zope a run
try and, ... if my instinct is correct, you will want no other thing.

hope it helps,

pedro

I've used PHP3 since it was PHP/FI and done lots of work in it. It's 
database integration is excellent and the ability to include PHP3 
code into an HTML document and have it 'executed' is really neat (I 
think CGI's are ugly, whereas code in the delivered doc itself is 
elegant - my opinion, YMMV). I've run PHP on Solaris and Linux, and 
used a lot of the contributed code.

Since I found out about Zope, I've desubscribed myself from the PHP 
lists and been focussing on Zope almost entirely. I posted a message 
a while ago 'Tough Questions about Zope' and got some excellent 
answers, for more details I'd check it out in the archives.

PHP3 is a scripting language, and is relatively easy to get started 
in. I may get a 16-ton weight dropped on me (in joke) but I think 
that if you're used to scripting languages already, you may get your 
application up and running faster in PHP3, as Zope scripting ('DTML') 
requires a bit of a mind-flip.

However, once your application gets more complex, I think you'll find 
that Zope will start to pull ahead of PHP3 and eventually pull very 
far ahead. The list of things that Zope provides 'out-of-the-box', 
which are very difficult to do in PHP3 is pretty long; access 
permissions (at varying levels) at a per-directory and per-'object' 
level, editing of web pages online, *undo* - yes, undo!, and versions 
are the things that come to mind initially. There are many others. 
Obviously, there are some things in PHP3 that are a bit 'unusual' in 
Zope too (setting variables for instance! :)

The scripting language of Zope is Python - I've bought several Python 
books (personal rec: Internet Programming in Python by Watters, van 
Rossum and Ahlstrom - top geezers in the Python world) and have found 
it to be quite a beautiful language. You can't install Python 
programs 'directly' into your DTML document, but 'External Methods' 
seem quite easy to write. Once you become familiar with 'Products' 
and what *they* can do, your jaw *will* drop.

> Are there people, using PHP3 next to Zope?

This is a question I asked. The upshot is that it's pretty difficult 
to do in seemless way with current implementations of Apache (ie more 
or less impossible) but that a later version will do that.


> ps. Has Zope the capability to easely make these scripts? I mean not
> text-based , but in a certain IDE or RAD application?

I would say, yes. I would suggest reading the FAQ, then the 
documentation, reading the documentation again (especially the DTML 
and ZSQL documents), read it once more and then if you do decide to 
try Zope over PHP3, have a go at your application. I think that it's 
highly likely that you will be able to get by with just some DTML and 
a database connection.

I'm not knocking the documentation here - the DigiCool guys (and 
gals?) have relatively recently embraced the open-source concept and 
seem to be doing 10 things at once.

I don't think you're stupid at all! :) There are some new and unusual 
concepts in Zope that many people will not be familiar with 
(particularly if you're coming from a 'traditional' web-publishing 
environment).

If it helps, I've been in contact with several other people, both 
here in the UK and elsewhere who are *extremely* excited about what 
Zope is and what it can do.

> Thanks in advance.
> Kind regards, Tom.

You're welcome - I got a lot of help starting out, just trying to 
pass it along... :)

Maybe It's self.l that causes the error. It's hard to understand what
you want, but I feel it should be

   for i in l

Maybe I can help you with this. The traceback you get is probably the
standard error raise in ExternalMethods. To debug external methods I use
try/except/raise code blocks and when I get an exception I return it to
the screen. Something like this

def mymethod(self):
    try:
	mycode
    except:
	import sys
	return sys.exc_type, sys.exc_value
    
    return something

Not yet. ZServer is multithreaded, but Zope itself isn't. This is because
the BoboPOS (cuurent version 2) doesn't support concurrent access. The all
new ZODB 3 will support this, and then Zope can (will?) become
multithreaded as well.

   So I have some time before I'll see problems with concurrent access to

Ok, I'm dumb.
After some digging, I found that the problem lies in
the expression 'self.l'

'self.' gives access to the object hierarchy, not the variables
namespace.

So, I solved my problem by writing 'self.REQUEST['l']'
instead of 'self.l'

Also, I think that this should be clearly documented.
Apparently, the only way to acess variables namespaces
in external methods is through self.REQUEST
This confuses a 'normal' python user whose variable
namespace is usually accessed through self.

Can someone confirm (or infirm?) this?

I believe that you can just ask for it in your function signature:

def my_method(self,l):
  return l + ' is cool!'

In your external method l is a local variable. You can access it by simply
referencing it. something like

def spammethod:
	l=[]
	for i in [1,2]:
		l.append(i)
	return l

It can do the same thing, and more.  This isn't a hack on PHP3, but Zope
has many more components and widgets out of the box.  It's also object
oriented, which helps when your components scales, or when you want your
application to suddenly be stitched into four other application six
months from now that you didn't forsee.

>Or is this a complete different application? 

PHP has it's niche.  Tony 'tone' McDonald mentioned that he thought code
inside HTML is elegant, and it is, but it's even more elegent when that
code is for the layout of your user interface only.  Mixing application
code with HTML, or worse yet, making your entire HTML document one huge
script, is not so elegent.

Zope is an Application written in a scripting language (Python) that is
based on several components also written in Python and C.  One of the
components of Zope is Document Templates (DTML) which is also a
scripting language.  It's a bit complex, much more so than PHP's
underlying system.  Tony also mentioned that PHPs database itegration is
excellent, and I'd like to add that Zope's is also top notch.  A
particular nice thing about Zope is it's database abstraction layer,
what we call Database Adapters.  You can write program for any SQL
server and just change the DA when you change databases.  Or your app
could use two databases transparently; the DTML programmer wouldn't need
to know which database is being queried, it would just be a case of
calling the write SQL methods.

This also give some compartmentalization.  Your Python expert writes
your external methods, your SQL expert manages DAs and writes ZSQL
Methods, and your DTML/user interface expert uses all of these methods
to layout the application.

Comming soon.  The problem is (rumor has it) that Apache sends Zopes
output directly back to the browser, not giving it a change to run
through any other handlers, like the PHP one.

There is a web based interface.  The (IMO) ultimate programmer interface
is emacs, which can use Zope with FTP (if your using ZServer).

Whew.

Zope is a web application platform.  It is a framework for writing
applications over the web.  It is more than this, because it supports
more protocols than HTTP, but for your purposes you can call it a web
app platform.

Zope provides you with a standard set of services that your application
can build on.  Services include DTML, trasparent persistence of your
data, interface to databases, a management interface for developing and
managing your application, and a whole slew of out of the box objects
for you to use (like documents, files, methods, DAs, mail transport,
etc...)

Many people have mentioned Python in responses to your question.  Python
is an incredible language, but I think the application you described can
be done easily in Zope with no Python at all.  All you need is DTML,
some ZSQL Methods, and a good design and your done.

These 'benefits' you feel you might be missing out on you might not
need.  One of Zope's best features is the fact that you can just use the
components you want.  In fact, it sounds like you may just need
ZPublisher by itself.  If you go to our site and look at the Components
section you'll see where you can download it. ZPublisher is just the ORB
part of Zope, it traverses your python module and calls your methods
based on the URL.

Now, you can still USE Zope with these application you write.  Even if
you write a pure ZPublisher application, you can then plug that
application right into Zope with the External Objects product available
in the contributed area.

Zope,Python and MySQL all work fine and the ZMySQL module compiled fine

Hi all,
just thought I'd check my sanity here...

the way to get roman numerals showing up as the label on a batch object is :

      <!--#/if previous-sequence-->
isn't it? - I get a NameError, with the following traceback ('sub' is 
nowhere in my document btw)

<!--

Message-ID: <3.0.1.32.19990326200338.009363e0@poirot>

Hi,

Thanks to all the reply I got for my question PHP3 or Zope.

I'm wanting to give it a try, but ....

I've RedHat 5.2 installed with running Apache

I'm trying to install Zope, but am expiering some problems :

I've downloaded the binary and installed it into 

 /usr/local/dc/Zope-1.10.2

installed it with ./install -sAdmin:Admin

the var directory of Zope is permissioned for nobody (done by Zope)

As in the manual, Zope created access with Admin:Admin, but it says login
with Zope:Admin

copied the Zope.cgi to the directory /home/httpd/cgi-bin

I want to use it with Apache so I had something to change in the conf file
of Apache... Apache has 3 conf files. At the moment it is written in all 3
of the files (because none of them work!).

This is the piece of script I've written : (from WEBSERVER.txt)

#Zope configuration maps /Zopz/ to the Zope.cgi CGI script

RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP-CGI-AUTHORIZATION:%1, t=application/x-httpd-cgi,l)]

When trying to browse to http://localhost/cgi-bin/manage I get the password
dialog... I enter Admin , Admin and am refused (same with Zope, Admin) ....

What am I doing wrong?????

--------------------------------------

Now try to use ZopeHTTPServer

I can't find anywhere the file serve.sh

BUT I tried to start it with start

then going to webbrowser http://localhost:9673/manage

I get a message of DNS problem etc...

So not even a question of password...

----------------


Can somebody tell me what I've done wrong? I want to get it to work with
Apache... What do I've to do?

Thanks in advance,

Tom.

Hi,

I noticed that if you're browsing two different Zope sites using the
same Netscape, the management tree on the second one is incorrectly
displayed (the COLSPAN is increased by two).

Has anyone noticed this before?

Ok, I've updated the package to remove the bug that killed it after the
first shutdown/cache loss. The _v_ technique certainly served to prevent
the saving of the variable, so when the system came back up, before I
use the _v_ variable I was testing it to make sure it was higher than
the stored value. I added a test to make certain that it exists... Is
there a way to register a function (or some __func__) that gets called
the the instance is reloaded?

It seems fairly stable now, so I'm calling this 1.0. 

Please send bug reports to shawh@sths.org.

BTW, has anyone actually tested this other than me? 
I thought from the comments I had read on the list that there were a
fair number of people who were perturbed at the lack of a counter in
Zope. Was I wrong? Am I flogging a dead horse here?

Subject: [Zope] Method icons
Message-ID: <36FBFDF1.23E9F89A@digicool.com>

Hi all.  Here's a minor issue I'd like to get some opinions on.

  There are some ideas in Zope that cross 
  object types in Zope, like folders, methods, and
  content.  We reinforce the idea of folders
  by giving folders icons derived from folder
  icons.  I'd like to do the same thing for 
  methods.

  The basic idea is that there should be
  some basic icon that indicates that something is
  a method.

  It should be possible to decorate the icon to 
  indicate a particular type of method, such as adding
  angle brackets for DTML or adding a table grid
  for SQL, or OO (or glasses ;) for Python.

  Note that one complication is that the image 
  should fit in a 16x16 icon.

I've put some ideas at:

  http://www.zope.org/methodIcons

I'm curious what folks think of these and whether
anyone has any better ideas.

Jim

Hi Tom,

Try this:-

RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

Notice the underscores, where you had hyphens.

Message-ID: <Pine.SOL2.3.96.SK.990327183725.28104M-100000@sun.med.ru>

Hello!

   I am creating a record on Zope on postgresql.org:
http://www.postgresql.org/software/detail.cgi?oid=3440544

   I need a short informative description on Zope. Something like "Zope is
opensource web application platform - software complex for creating highly
dynamic web-sites".

   What is contact e-mail? I wrote zope@zope.org. Shouldn't it be
info@digicool.com?

Oleg.

Subject: [Zope] Automatically creating instances for each user?
Message-ID: <36FE35BD.AEBBC507@dougiamas.com>

Hi,

I'm new to Zope, but I'm eagerly learning it.  I like the
paradigm - it seems to fit the way I think.

This is my first post here.  I've hit a snag, and I'm hoping
someone more experienced can point me in the best direction.

I'm developing an application that needs user-modifiable pages.
I already have a Zope form where the user can edit text properties
of an object, and another page that displays those properties as HTML.

My problem is, I want each authenticated user to be editing their 
own instance of this object, and I also want the URL to be the 
same for each user.

eg  fred sees http://host/mypage as fred's editable page
    mary sees http://host/mypage as mary's editable page

What is the best approach I should take to achieve this in DTML?

Cheers,
Martin

Yes, the documentation is a bit unclear about this.

You'll need a Database Connection String like this: 
"webdb joe password".

"webdb joe password" should work if the database is running on the same
machine.

Message-ID: <3.0.1.32.19990329102524.0097e170@poirot>

Hi all,

Well, now I don't understand it anymore....

Just back from the weekend (where on Friday I had these installation problems)

Now went to the Zope directory and what did I saw? The 'Start' and 'Stop'. 
I wrote ./Start and then surfed to the correct address and it works!

Why did'nt it worked on Friday? The whole weekend searching for a solution
and then it appears it isn't needed... (almost)

But, still I would like to work with Apache... Why? Because I've heard it's
the best in web-servers... (I don't know it's through, but I believe it) Or
is the comming ZServer better?

Now, I believe I have to recompile apache again to make it ready for Zope,
isn't it? I thought I only had to put it in one of the configuration files,
but instead you've to write that script in the ./configure file.

Kind Regards, Tom.

Is it so that I've to recompile Zope? This means that I've to download the

   You need to install and compile ZPygres Database Adapter and add it as
described in ZPygresDA docs. You don't need to recompile Zope.

AUTHENTICATED_USER.getUserName() returns the name of the current user. You
could use this in the DTML of mypage to select the object you are working on.

Hi all,

I'm using Zope 1.10 with IIS 4.0 on an NT box.  All is working well, I just
have one small query which is slightly off topic, maybe.

The URL for Zope is 'http://localhost/scripts/z.exe' and I would like it to
be 'http://localhost/z/', I know that with Apache I could do a rewrite and
this works great with Apache, but does anyone know how I would do something
similar with IIS.

TIA

Nope,

With that definition, my_method expect to be called with the arguments
set, eg <!--#var "my_method('Zope')"--> to display "Zope is cool".

However, I want to get the variable l from the namespace. (application
variables made with REQUEST.set, Folder or document properties, etc.)
The question was: is self.REQUEST the only way to access the
variable namespace? And the only way to *modify* the variable namespace
from external methods (with self.REQUEST.set)?

By the way, I'd like to thank Stefan Franke and Pedro Vale Lima who
gave me a pretty quick answer. I did find the answer before they wrote,
but anyway, a thank is not that expensive :-)
Also, thanks to Paul who gave me such a useless answer. :-) (just kidding)

The error occurs because a value is appearing in
a pcgi reserved header record, possibly because your
application is sending something to stdout.  I'm
not sure where to tell you to start looking, but
if *all* you have done is uploaded .dtml files to
trigger the error, that's probably the place to
start.  I'm honestly confused why this should
happen.

Usually this means that the Zope process is unable to start up
for some reason (an import error, syntax error, etc.). I'm not
sure how changing DTML document objects could cause this, though.
You didn't happen to change any DTML that is read from the disk
(e.g., HTMLFile objects used from Zope, installed products or 
external methods) did you? If so, there is probably a dtml syntax
error that is being raised at startup time.

You are positively right.
I stupidly wrote <!--#var "some_method(var0=value0, REQUEST)"-->
notice the non-named parameter after a named parameter.

I haven't tried it yet with other publishing mechanisms (ZServer,
ZopeHTTPServer,
which don't use PCGI), but if these servers also dies for such oddities,
this might be
a bug in error handling. Stay tuned for more informations.

Many thanks to Brian and Jeff who took the time to respond to me.

Message-ID: <613145F79272D211914B0020AFF6401907BBDA@gandalf.digicool.com>

Greetings,

As promised, it is possible now to browse the Zope public CVS repository
through the web.  If you're interested in looking at the latest Zope
developments, this is a good place to start without having the check out
your own copy.

This site is also handy for viewing the various evolutions of Zope, and
for getting pretty colored diffs between versions.  If you want to know
the difference between two recent versions of a certain file, cvsweb
will show you in glaring full color.

The web view of the Zope CVS is more fragmentary the the view you get
with the 'cvs' command.  If you want to check Zope out of the public
cvs, it is recommended you just check out 'Zope', which is an options
not shown on the web cvs.  The public CVS uses its module file to stitch
together the various components that can be seen on the web view into a
Zope distribution.  Complete instructions on how to do this can be found
at:

http://www.zope.org/Community/CVS_public_access

The web interface can be found at:

The first release of Aqueduct docs had a table with examples of
connections strings for some databases. This table disappeared in the
latest docs. Shouldn't it be the case to take it back?

After everything compiled fine I try to import MySQL and get the following
error:

rdi% python
Python 1.5.1 (#1, Mar 25 1999, 13:52:32)  [GCC 2.7.2.3] on sunos5

ImportError: ld.so.1: python: fatal: relocation error: symbol not found:

Does anyone have any ideas??
MySQL works fine as well as Zope.
Do I need to install the Sun ld.so patch??

TIA Daren

Yes, I've seen it in Principia and Bobo for cookies in the form:

.com.au  TRUE    /       FALSE   933422008       MC1 GUID=083F5B8E21DE11D28B2C08002BB74F3F

The two problems being that cookies are usually only seen by the domain
that registers them, but some badly configured servers (most probably
Microsoft servers by the look of the cookies) only list the last two parts
of the domain name. This is fine for blah.com, but for overseas domains
like blah.com.au it means the cookie is returned for ALL .com.au sites.

This wouldn't be a problem, but since the cookies are returned to Principia
in the form:

MC1=GUID=083F5B8E21DE11D28B2C08002BB74F3F

parse_cookie breaks since it looks for key value pairs WITHOUT an equals
sign on either side. The extra = really confuses it.
To fix it change the re in parse_cookies in cgi_module_publisher.py from:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-=\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'
                     ),
 
to:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'

I'd like to be more precise. Suppose my_method is:

def my_method(self):
    if self.REQUEST.has_key('my_var'):
        return "oh yes"
    return "boooo"


Now, I write in DTML:

<p><!--#var my_method--></p>
<p><!--#with "_.namespace(my_var='my_value')"-->
<!--#var my_method--><br>
<!--#var my_var-->
<!--#/with--></p>

Believe me or not, the result is:

boooo
boooo
my_value

You can now understand why I ask how to access the variable
namespace from external methods. How can I test the existence
of my_var, and access its value???

Keep the good work, I might ask you some of your photos for
my daily worship :-)

Message-ID: <3.0.1.32.19990330122825.009293a0@poirot>

Hi,

I'm getting really frustrating on this subject. Pff, I believe the
Zope-people have made already a great effort in their documentation. So I
guess my problem is my own bad english. shhg.

I finally got the Postgressql adapter compiled, thanks to two great people!
Thanks for this already.

But now I'm confused? How to use it in Zope? When I go to the product
management I see the all the installed products including : ZPyGreSQLDA
(broken product APyGreSQL).... I guess here is already something wrong
(broken... is not a positive word :-( )

But then, how can I work with it? How can I use it in Zope...? How can I
add it to the 'Add list' . I read of a connection string... but where to
place it?

Sggh, I've read in the manuals, Q&A, ... but I still don't get how to use
it....

Please, somebody, help...!

Thanks in advance,

The Idiot,

Tom.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC93@peter.sths.org>

First thing, if your product is broken you won't get anywhere. So, first
step is to delete the broken product, and shutdown and restart your zope
server. This is because Zope apparently won't replace a broken product
with a working one. 

If it is still broken, click on it, and then on the screen that comes
up, look for the 'traceback' tab on the top of the screen. Copy this
traceback and mail it to the list. 

If your product no longer says broken, then you will be able to go to a
folder above where you want to use SQL methods, and from the pull-down
menu beside the add button, choose to install the SQL Adapter. 

I don't know for certain the format for the connection string, but if
you go to <zope_homedir>/lib/python/Products/ and look in the directory
for the ZPyGreSQLDA and read the top of any *.py file you see, it should
say. 

Once you have a working adapter, you can add an SQL Method, and it will
list your adapter's id on its list of db connections. 

From this point on the documentation in the SQL Guide should be
sufficient.

Good luck!

    If I'm really lucky, I might be getting a contract to put together a
rather large site which includes selling the client's product over the web.
They'll want to be doing credit card transactions.  Has anyone been working on
a shopping cart app for Zope, or perhaps even utilities to interact with a
credit card transaction service?  It's much quicker to buy than write!

Well, this is an interesting question. In my experience, seldom do people
try to munge the DTML namespace from within an External Method. I guess it
could be done (perhaps by passing the special underscore variable to an
External Method), but I wonder if this is really the best way to solve your
problem.

Well let's see what's going on here. You call my method, it acquires the
REQUEST object and looks for a 'my_var', doesn't see it and returns
'boooo'. so far so good. Now you push a namespace containing only 'my_var'
on to the DTML namespace stack and call the method again. Not surprisingly
the method does the same thing as before, it acquires the REQUEST and finds
that it does not contain 'my_var' so it prints 'boooo'. Finally you call
'my_var' which is found in the DTML namespace and 'my_value' is printed.

So the lesson is: the DTML namespace is not the same thing as the REQUEST
object.

For more on how DTML namespace works see my advanced DTML how-to:

http://www.zope.org/Documentation/HowTo/DTML

My advice to you is to keep things simple. It's easy to confuse yourself
with the complexities of DTML. In general, I would suggest that your
External Methods take well defined arguments and return results, rather
than modify the objects passed to them. Then allow the DTML to pass those
arguments and munge its own namespace in response to the results of the
External Method. Of course, this schema isn't always the right one. Finally
I would suggest that you, don't munge the DTML namespace from within an
External Method unless you have a good reason to, I think that this would
make the DTML even harder to understand.

Good luck.

Can I recover? The db doesn't contain anything important so it's really

It looks like you're running an older release 1.9.x something?  1.10.x
will automatically fix the database under 90% of the circumstances by
simply truncating the bad record.  This should fix your problem.

BTW, it's always helpful to give information on what release of Zope
you're using.

At a minimum, you can truncate the data file (var\Data.bbb) 
at the position indicated. (Let me know if you need help with this.)

You could also just delete the database (var\Data.*) and
a new database will be created when you restart.

I'd appreciate it if you'd send me the corrupted database
as a zipped or gzipped attachment in a private email.

Also, what version of Zope were you running? What OS?
What products (not included in the Zope distribution) did
you have installed?  Can you tell me anything more about what 
might have led up to this?

I think what you want is access to the dictionary's items() right?

<!--#in "dictionary.items()"-->
  <!--#var sequence-key--> : <!--#var sequence-item-->
<!--#/in-->

The mapping attribute is not relevant here. It means treat
sequence-items as mappings not instances, that is to say, look up vars
with __getitem__, not __getattr__.

Message-ID: <Pine.BSF.4.05.9903301224520.1978-100000@nomad.dataplex.net>

I'm trying to convert shell scripts into DTML methods.

Please excuse the pseudo code. I'm using it to represent the problems
that I am addressing.

set basket_total=0
set taxable_total=0
foreach item( 'apple', 'peach', 'soap', 'pear', 'plum', 'magazine' )
 if (! isfood($item))
  @ taxable_total = $taxable_total + price_of($item)
 endif
 @ basket_total = $basket_total + price_of($item)
endfor
print "Of the $basket_total total, $taxable_total is taxable"


1) Can I generate an explicit list rather than getting it with
as the result of either a database query or enumeration of an object?

2) How do I generate "local" variables.
I know that I could use the REQUEST variable as a global property store.
However, because of nesting, global (REQUEST) variables are not desirable.

I'd like to say something like the following:

<!--#WITH "LOCAL_NAMESPACE (basket_total=0, taxable_total=0)"-->
 <!--#FOR "['apple', 'peach', 'soap', 'pear', 'plum', 'magazine']"-->
  ...
  <!--#SET basket_total=basket_total+price ...>
 <!--#/FOR-->
 ...
 <!--#var basket_total--> 
 ...
<!--#/WITH-->

Does Zope's DTML have constructs to address either of these?

Subject: [Zope] External Methods
Message-ID: <370125A1.305733AC@kw.igs.net>

Please excuse my lack of zoping intuition but I hoped someone could help
with this problem. I read all the doc's I could find but seem to be
missing something. It goes like this...
I have a ZSQLMethod that returns some tuples. There is a field in the
tuple which I wish to use to lookup an external file and return a jpeg,
if available.
I've created an external method called 'getPic' which I wish to pass the
key field to locate the file with but I can't seem to get at the
variable.
e.g
----------
<!--#in sequence -->
  <td><!--#var pic_key null=""--></td>
  <td><!--#var "getPic( <!--#var pic_key --> )" --></td>
<!--#/in -->
----------

This doesn't work for reasons not obvious to me.

I've tried creating a class to handle the records. No go.
Basically, the External method can't get at the vars defined on each
loop thru the sequence returnd from the SQLMethod.

Any insight would be appreciated.

thanks
jb

I would like to trigger a DTML document to print after the user creates
it. ( There are a few documents in my project that need to be snail
mailed)   
Circumstances aside, they aren't allowed to print from Navigator, so I'd
like Zope to shoot it out without the user having to have a printer
configured.  If a printer is configured to work with the server, can
Zope send it to lpr? I have zero experience there. :-(  

Any suggestions?

Brad,

Thanks.  Regretably, we aren't really using any Microsoft Products (Too
bad, we could have got a virus yesterday :-()  The clients are(and a
browser on the server could be) running Netscape Comm 4.08.  I'm sure
there is a similar way of controlling Netscape--Any body have a guess?

Message-ID: <19990331004836.5871.rocketmail@web129.yahoomail.com>

I am thinking about implementing a dynamic site using
zope and as little python as I can get away with.  The
site is modeled after
http://c2.com/cgi/wiki?WikiWikiWeb  

This is a dynamic site in that all the web pages are

Subject: [Zope] external methods
Message-ID: <003c01be7b40$e0c23560$147800a0@pc-pi0>

Hello,

Thanks for your answer.
In fact, I want to write external methods to replace DTML methods which work
like a charm, but are not very readable (a lot of iterative stuff, given the
fact
that mySQL doesn't support sub-select) and pretty slow.
I have used python for several years right now, but DTML is new for me.

My users can search in our news database in several ways, that are
covered by different SQL queries. However, the output of all these queries
are the same, so I use a single DTML method to display the result.
So the name of the ZSQL Method is only known at runtime, and I use something
like:

<!--#in "_[query]"-->

to display the result. The arguments of the query are taken from the
namespace.
I can also write:

<!--#with "_.namespace(cooked_arg0=some_expr(arg0),
cooked_arg1=some_expr(arg1)"-->
<!--#in "_[query]"-->
<!-- ... -->
<!--#/in-->
<!--#/with-->

If I want to cook some args before feeding it to the query.
All these work from DTML.

Now, I want to write this in an external method.

def results(self):
    for record in getattr(self, self.REQUEST['query'])(self):
        pass # do watever

'query' has to be in the form REQUEST variables (that is not a problem), but
I cannot be sure that any arguments that the query need are all accessible
through
REQUEST.

>Well let's see what's going on here. You call my method, it acquires the

I wrote this to test wether an external method has access to the entire
namespace,
or only to REQUEST variables.

>So the lesson is: the DTML namespace is not the same thing as the REQUEST
>object.
So I come back with the question: is there any way to access the DTML
namespace
from an external method. Apparently there is not

>For more on how DTML namespace works see my advanced DTML how-to:

I have already read it.
By the way, let me ask you a question (again. I already asked that, but the
answer
was not very clear, and I finally gave up):

<!--#var my_var--> and <!--#var "_['my_var']"--> are the same.
So instead of writing:

<!--#if var0--><!--#if var1-->
<!-- ... -->
<!--#/if--><!--#/if-->

I usually write:

<!--#if "_['var0'] and _['var1']"-->
<!-- ... -->
<!--#/if--><!--#/if-->

But almost everyone told me that

<!--#if "var0 and var1"-->

also work. So I wonder: are <!--#var "var0"--> and <!--#var var0-->
the same??? The DTML User's guide say that in an expression,
variable are not called by default, but _['var0'] calls var0 if possible.

To keep things simple mean I have to write several times the same external
method
with different queries and differents arguments each time. this is not what
I want.
I can remember that in DTML I only need one DTML Method.
I would really like to replace some of my DTML Methods with external
methods.

That's enough for today. Let's take some rest :-)

Subject: [Zope] multiple SUBMIT buttons for same method, with parameter
Message-ID: <129.78.8.1.126.8141.922865008.414.1008>

I can use the following in a DTML document to call a specific method:

  <INPUT TYPE="submit" NAME="mymethod:method" VALUE="Delete this item">

But what if I wanted to have lots of them?

I'd like to have multiple SUBMIT buttons, all referring to the same method
but diffentiated by parameter - possible?

Ie: something like:

  <INPUT TYPE="submit" NAME="mymethod:1:method" VALUE="Delete item 1">

passing the parameter '1' to 'mymethod', and then later

  <INPUT TYPE="submit" NAME="mymethod:2:method" VALUE="Delete item 2">

and so on.

Incidentally, is the ':method' trick documented? - I can't find it in
the DTML guide.

Message-ID: <3.0.1.32.19990331105851.00931700@poirot>

Hi all,

First of all, thanks to all with their great support and help. At the end
of last week I found out about Zope. It looked really interesting, so I
wanted to give it a try. Monday after several problems and with lots of
help I could manage to enter Zope. Not from Apache as I would like, but
from the HTTPServer.
Next I wanted to attach Zope with my PostGresSQL demo database. Boy, did it
gave me some problems (and all because of my lack in knowledge of Linux).
But again several people helped me and today it is solved! Yep, it is done,
the hard work can begin. Now, I've to convince other people that Zope is
the way to follow. 

At first blink, Zope is a really nice and great product. I hope it will get
the attention it diserves.

Still, some work on the documentation, although they already did a great
job! Most thingies are written down.

Kind Regards, Tom.


Now some questions:

1. Have you used CSS-sheets in Zope and how did you use them? Did you
incorporated them into Zope or not? Have you got a little sample?

In Zope, this is pretty easy.
Create a property at your top level of type 'lines' and called 'css' 
(you can also create a DTML document/method if you like). Populate it 
with good CSS things like (this is from the Zope site itself 
actually).

<STYLE TYPE="text/css"><!--
	.clean { font: 10pt Verdana, Geneva, Arial, sans-serif }
	.clean dt { text-decoration: underline }
	th.clean { font-weight: bold; }
	.headbottomrow td { border-bottom: 2px solid #936 }
	.header { color: #004488; font-weight: bold; font-size: 14pt; 
font-family: sans-serif }
	.smallclean { font: 9pt Verdana, Geneva, Arial, sans-serif }
	.smallclean dt { text-decoration: underline }

H1, H2, H3, H4{
  font-weight: bold;
  color: #000000;
  font-family: Verdana, Helvetica, sans-serif;
}

H1{ font-size: 16pt;}
H2{ font-size: 14pt;}
H3{ font-size: 12pt;}
H4{ font-size: 10pt;}

/* end hiding content from old browsers */ -->
</STYLE>

In standard_html_header you put something like
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#var css-->
</HEAD><BODY BGCOLOR="#FFFFFF">

and you're away...

You may want to change standard_html_header so it doesn't crash if 
css is not present.
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#if css-->
<!--#var css-->
<!--#/if -->
</HEAD><BODY BGCOLOR="#FFFFFF">

Now where it starts to get really cool is that all your documents 
*below* the top level get the CSS information by acquisition, but you 
can change CSS information in folders by creating a new CSS property 
or document within that folder.

Tres Neat.

I just installed Zope on a Netscape Enterprise Server (3.6). I compiled
and installed the nscgiauth plugin, and all seems to run OK, except for
one thing:

When I try to add items to the site through the manage screen, I get:

        Not Found

        The requested object does not exist on this server. The link you
followed is either outdated,
        inaccurate, or the server has been instructed not to let you have
it. Please inform the site
        administrator of the referring page.

When I open the frame into a new window, I see that the URL looks
something like:

http://www.foo.bar.net/Zope/GATE/manage/.?%3Amethod=manage_addDTMLDocumentForm

When I edit the URL by hand to remove the "."

http://www.foo.bar.net/Zope/GATE/manage/?%3Amethod=manage_addDTMLDocumentForm

It works fine. What is going on here, and what do I need to do to change
it? I plan on having other people from other departments access resourses
on Zope to create their own objects, and I need this to work right out of
the box.

Thanks in advance for any help.

First off, your the first person (I think) that has come forward with
the information that they are using any version of NES higher than 2.0,
which is what the nscgiauth plugin was written for.  As I have heard
(but don't know) there were some significant changes between the 2.0 and
higher versions of the NSAPI.  So, that you got it to work at all is
pretty good.

This is unreported behavior, which leads me to think that nscgiauth
needs a little tweaking.  As nscgiauth is unsuported you will have to
experiment with this a little.

If your looking to showcase this and you can't spend any time working on
nscgiauth, I would suggest using either Apache, ZServer, ZopeHTTPServer,
or IIS, all of which Zope runs out of the box with.

I think that you missed my point.

"I" can write python just fine. However, every time something changes, new
python functions must be written. It is desirable to allow 
"DTML programmers" to do simple things which they can accomplish with simple
local variables.

What I think I should do is create a function, "LOCAL", similar to REQUEST
that stores temporary variables. Unlike REQUEST, LOCAL would be bound to
the namespace multiple times, each with a different context stack.

<!--#with "_.namespace(LOCAL=LOCAL.create('basketTotal','taxable')"-->
  <!--#call "LOCAL.set('basketTotal', 0)"-->
  <!--#in "['pear', 'peach', 'boot']"-->
    <!--#call "LOCAL.set('basketTotal',
                             LOCAL.get('basketTotal')
                             + priceOf(_['sequence-item']))"-->
  <!--#/in-->
The total basket will cost <!--#var "LOCAL.get('basketTotal')"-->  
<!--#/with-->

Or perhaps we can trick the namespace into showing basketTotal without
the LOCAL.get reference.

Can the Zope server provide virtual domains or do I need to use Apache??
Right now I have Apache set up with 4 virtual domains and would rather
just use the default Zope httpserver.

Well, the only difference that stuck out to me were the include files for
NSAPI.
nscgi  calls for several, but in 3.x all the header files have been
combined into
one, "nsapi.h". I modified nscgi.c to call for this one header file and it
compiled
cleanly. It does its job very well, and am not all that certain that the
problem I
am having is related to nscgi at all.

Well, I am a contractor and really don't have that option. I have tried to
sell the idea of using Apache here, but they have already bought massively
into Netscape. If I cannot get Zope to work, I may end up recommending a
commercial package, at least for this case.

Has anyone built Zope on a BSDI machine? BSDI doesn't support shared
libraries, so everything has to be statically compiled into python.
I just got it to build (python w_pcgi.py finished), but there doesn't seem
to be a new python binary anywhere with everything compiled in. To get it
to compile, I went through and deleted all the '*shared*' from the 'Setup'
files. Any tips?

As a side note, I was planning on using the binary porting kit to get it
built, then contributing this back to the community. But the porting kit
is still Zope-1.9. Is there any plans to update the porting kit.

Thanks in advance for any help,

Message-ID: <613145F79272D211914B0020AFF6401907BBF0@gandalf.digicool.com>

Greetings,

NotMail-0.1.0 and IMAPAdapter-0.1.0 have been posted to the prereleases
area of the site:

http://www.zope.org/Download/Prereleases/Mail

These are first beta cuts.  Both programs are also available in the
public CVS.

IMAPAdapter allows you to work with IMAP folders and messages in the
context of an authenticated IMAP user.  Using IMAPAdapter, it is very
easy to build IMAP client functionality into your Zope site using DTML.

NotMail is a simple web IMAP client that requires IMAPAdapter.  Its mail
purpose is to verify the operation of IMAPAdapter and to provide an
example implimentation of IMAPAdapter's client functionality.  NotMail
is mostly DTML, and what Python there is is just specific to sending and
replying to mail, all other functionality comes from IMAPAdapter.

It is important to note that IMAPAdapter looks like a user folder to
Zope, in Zope parlance, we call this a user database.  It's not a user
folder, because it doesn't not contain users.  If Zope tries to validate
a user against an IMAPAdapter, the IMAPAdapter will contact the IMAP
server, try to make a connection with the uid:pwd that the browser
supplied, returning either a user object or None, depending on the
success or failure of that connection attempt.

This means that using IMAPAdapter is quite simple.  Here is a snip of
DTML to display all an IMAP users mail folders with the #tree tag.

   <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

The user object that IMAPAdapter returns (if the user is valid) is
placed into AUTHENTICATED_USER.  emapFolderTree is one method of this
user object, but there are about a dozen or so more methods to do
various imap related things like adding/deleting folders and listing and
fetching messages.

If you plan on installing and trying out NotMail and IMAPAdapter it is
important to know that you can configure the roles that IMAPAdapter
associates with users that it returns.  The two default associated roles
are 'NotMail' and 'IMAPUser'.  If you want NotMail to work, you will
need to add one of these roles (or any roles you care to define as
IMAPAdapter's default roles) somewhere above NotMail/IMAPAdapter and
then assign that role the 'View' permission for NotMail's DTML Methods.

Um, what VERSION of BSDI are you using?  I haven't usd anything since
3.0, but I SWEAR it has standard BSD style shared libraries, same as
FreeBSD, OpenBSD and NetBSD... It'd be a huge step backwards if it
didn't.... are you sure it just didn't auto-detect the method right?

Alright, I guess I was jumping the gun a bit with my assumptions about
shared library support. It does support them, just not in a format I'm
used to (based on my Linux/Solaris experience). 

Ok, so then mabey I messed up in autodetecting as you mentioned. How would
you suggest I do this?

Here's a few lines of the errors it reports when trying to compile any of
the shared extensions... 

www ~/Zope-1.10.2-src/lib/python/SearchIndex 242> make
gcc  -g -O2 -I/usr/local/include/python1.5 -I/usr/local/include/python1.5
-DHAVE_CONFIG_H  -I/projects/_/python -c ./Splitter.c
ld  Splitter.o  -o Splitter.so
./Splitter.c:105: Undefined symbol _PyString_AsString referenced from text
segment
./Splitter.c:114: Undefined symbol _free referenced from text segment
./Splitter.c:126: Undefined symbol _PyString_Type referenced from text
segment
etc.... (many more Undefined symbol errors)


So... any tips for compiling the Zope extensions as shared libs? I'll
probably keep working on the static python solution, as I'm actually
making progress on this, and I really have no idea where to start with
shared libs on BSDI (no good leads on dejanews, and egroups is
non-responsive as usual).

Thanks,

Here are some things I've found in previous struggles to
get Zope compiled on bsdish systems -- I'm no guru, though,
and I've seen different things work on different bsdx flavors:

o you usually need to add -rdynamic to LDSHARED in your Makefiles
  (this should be reported & worked into python's makefiles, IMHO)

o I havent been able to get threads going on many bsd flavors - so
  you may not be able to pass --with-thread to configure

o I find that extensions will all appear to blow up with unfound symbols

  (such as those you reported) - you need to run make -k and ignore the 
  errors ;)

o On some systems, I had to run make -k, ignore the errors, and rename
  the output .o files for the extensions to .so :(

o I seem to remember having to use shlicc on .so files, but
  I dont recall the details...

Hope this helps - please post a status rpt if you get it working, so
that the gory details will at least be captured. This is the sort of
thing that should be in an installation FAQ somewhere.

In the pcgi/Util directory, you'll find a killpcgi.py 
script.  You could hack it to perform a restart, i.e.
launch a new pcgi process after killing the old one.
This would speed up your initial connect time and be
much faster during debugging (multiple restarts).

My Zope Zen seem to have gone negative (started at zero - and just got worse
:( ) but HOW do you install it.  I could find no mention of any "lever"s in
the ZMG.pdf,
and I have tried as many ways as I could think of to get my Zope (1.10.2 on
ZAP) to read/import the FAQ product, but no cigar - not even close!

Where does one put which files, and what procedure does one go through to
invoke said "Lever" functionality.  Sorry about this, but surely I can't be
the *only* one that is totally lost.  (Come to think of it, maybe I can!)

It certainly looks like you are having a problem, but since I developed to
FAQ Tool under win32 and it works fine for me under Linux, I don't agree
with you assessment of the problem. Would you please file a bug report in

Subject: [Zope] acquisition from parent within standard_html_header
Message-ID: <010201be63c8$48369be0$147800a0@pc-pi0>

Hello,

I want to *add* content to the default standard_html_header in a subfolder
that we call, say, SF. The standard_html_header in SF reads:

<!--#var standard_html_header-->
<!-- other content-->

But since an object acquire from itself, this did not work (infinite
traceback,
obviously because the stack is filled with recursive calls)
So I wrote:

<!--#with aq_parent--><!--#var standard_html_header--><!--#/with>
<!-- other content-->

And it works for object accessed within SF. But when I create sub-folder
*under*
SF, say SSF, I end up with an error.

How could i write this?

I assume this means Zope will also appear in the Application Server list of

I meant, doing the equivalent (catching exceptions) not implementing the same

I got it working using the following code:
<!--#with "PARENTS[-1]"--><!--#var standard_html_header--><!--#/with-->
<!-- other content -->

This only works when this code is in a sub-Folder, and the standard_html_header
can be found in the root folder.

Does python have anything equivalent to Perl's taint mode? Because if it does
then this could be used. That and restricting allowable APIs from internal
methods - again, if this is possible.

Well, I found that standard_html_header were called several times, and
that's what caused the error.
Let SF/standard_html_header be:

--------8<--------
<!--#with aq_parent--><!--#var standard_html_header--><!--#/with-->
Hello!
--------8<--------

Then, when I access http://mysite/SF, I get:

--------8<--------
[pretty standard_html_header]
Hello! Hello!
This is the index_html document in SF.
--------8<--------

Why is Hello! printed twice???
From SSF, I get Hello! printed 3 times...

EGroups archives the mailinglist. At http://www.egroups.com/lists/zope you can
find a search interface, which quite often actually works.

and to let apache authenticate /cgi-bin/Zope/). I also grabbed the
latest Zap release, but that one din't work (broken?). Also had a look at
the zap.conf file and tried using some in my httpd.conf file, but I still
had no luck. 

Now - here is my current config:

Linux 2.0.35
Python 1.5.1
Zope 1.10.2
Apache 1.3.4

Something there that doesn't play well together?

If not - what is wrong??

Appreciate all the help I can get!

This may sound like a bit of an obvious suggestion, but it caught me out.

Check the Directory directive for <apacheroot>/cgi-bin and make sure that
the ExecCGI option is set.

It should look something like this:

<Directory "/www/cgi-bin">
    AllowOverride none
    Options ExecCGi
    Order allow,deny
    Allow from all
</Directory>

Apache 1.3.4 by default doesn't have the ExecCGI option set.

I don't get a traceback because I didn't "fiddle", the FAQ item shows up 
in the control panel, but is not in the Add drop-down.

I'm running 1.10.2 on NT with ZServer.

The 'fiddling' involves disbling the exception handling of the product
initialisation. Normally, a 'Levered' product, that has been distributed, has a
product.dat file. This file contains the compressed pickled reprensentation of
the product, which basicly consists of other Zope objects, with a Principia
Factory.

When Zope can't uncompress and depickle the product.dat file, you only get to
see that the Product is installed, but it doesn't contain anything (which a
Levered Product actually should), and nothing else happens or can happen. If
you want to know more on how to use the 'Lever', read up at
http://www.zope.org/Documentation/Guides/ZMG/ZMG-HTML/ZMG.html#pgfId-986684
(Zope Manager's Guide, Creating Zoipe Products).

When you disable the exception handling in initializeProduct in Product.py, and
restart Zope, it will exit with the traceback I reported.

I have reported this to DC with the Collector, but I used Win98. You are using
WinNT, which is interesting.. Something goes wrong with decompressing the
product.dat file on win32 platforms (Amos says he tested it succesfully on
Linux).

I don't want to get into a language war, but as someone who lives and
breathes security, taint mode is a joke.  Python's rexec module would be
great (as would Bastion), but this is going to require a much higher
level of ZopeZen to implement than I currently have.  Yes I know my
proposal was wrought with huge security problems, but regardless it is
valuable to a some people in the near term (such as those of us on the
STarship).

BTW, requiring write access to the file system is only trivially more
secure.

Unfortunately the ExecCGI option didn't help much. Thanks anyways. 

I'm still stuck at the
point where I get 'Authorization failed'. I've checked and double checked my
Zope/access file and I use correct username and passwd. The filepermissions
should also be set correct (according to the instructions given in the
INSTALL.txt file). Problem is, as far as I can tell, connected to the way
the rewrite module does the rewrite....

Has anyone confirmed that the way the WEBSERVER.txt file says to rewrite the
authorization header actually works?

If it works - is there someone that can say exactly how apache should be
configured and compiled to get it working (best of all also put in a working
httpd.conf also)?

And again.....Appreciate all teh help I can get!

We'd prefer that you start with the Zap distribution, as it removes a
whole bunch of variables.  Can you tell us what was the error with using
Zap?

The only difference between your setup and the setup used to compile Zap
is that Zap was compiled on a RedHat 5.2 machine, with the stock 2.0.36
kernel.  Your using 2.0.35, does that imply RedHat 5.1?  If so there
might be an incompatability with Zap on 5.1.  Has anyone on the list
gotten Zap working on this platform?  Also, please send us the details
of the error you get with Zap.  When you say it's broken, how does it
break?  Does the starzap script fail to run?  Does it say 'Apache did
NOT start sucessfuly' and then spit up the last 10 lines of your error
log?  If so, what are those lines?

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC3E@peter.sths.org>

You need to install python... Or adjust the Makefile.pre.in to look at
Zope's internal python, instead of trying to find the external one.

Actually, from a quick runthrough of the Makefile.pre.in, you should set
the enviroment variable PYTHON to point to the local python binary; I
mean the one internal to zope, like 

PYTHON=/home/zope/bin/python
export PYTHON

(in bash)

or setenv PYTHON /home/zope/bin/python

(in tcsh) ... (and no I am not quite certain on the syntax here).

The 'make -f Makefile.pre.in boot' appears to call $(PYTHON) with
parameters that cause it to return the proper location for the python
configuration files, etc.

Good luck.

Subject: [Zope] NotMail 0.0.5 alpha release
Message-ID: <613145F79272D211914B0020AFF6401907BAB1@GANDALF>

Greetings Zopesters,

I have been working on a little pet Zope Product project for months now.
Getting hired at digicool put the brakes on it a little but I have
finally gotten the time to polish it up a bit for alpha release.

Check out:
http://starship.python.net:9673/crew/furtrapper/NotMail

for NotMail.  NotMail is a clone of 'other' popular web-mail interfaces.
Please download and evaluate.  But first a word of warning:

NotMail is alpha.  It is being released with the intention of harvesting
other developers who are interesting in breaking it, fixing it, and
improving it.  Although it is a cool program, it is unstable (try
pointing it at Exchange!) and not complete.  I have tried to document it
in code as much as possible, and it does contain a nice README.txt.  You
are expected to be able to infer the workings of NotMail by the source,
or by telepathy, whatever.  If NotMail makes your hard drive partition
go bye-bye or makes your imap server think it's a dhcp server that's the
way the cookie crumbles.

Okay, now a word of license:

NotMail is released under the GNU General Public License.  Give yourself
a piece of mind and send the Free Software Foundation a donation.  You'd
do it for NPR wouldn't you?

Now a kind word about Digital Creations:

Digicool has been kind enough to let me waste a small fraction of my
time to release this today.  They also let me use their computer to
check my personal mail, etc.  Please don't infer that because I work for
Digicool that NotMail is a product of Digital Creations.  Please do not
submit NotMail bugs to the Collector or send reports to
support@digicool.com.  These things are for Zope and other Digicool
products.  It is ok to discuss it in the list but I'd prefer all
discussion happen using the cool Confera discussion that can be found in
the same place you can get NotMail.

Regards,

Michel

What I did:

1) Extract the Zap distro into my top level Zope dir. Entered the Zap dir and
did ./startzap. 

This happened:

'./startzap /usr/local/Zope/Zap/bin/zap: No such file or directory'

2) I figured the httpd equivalent 'zap' was broken and replaced it with my
httpd (from apache 1.3.4). Again I fired up zap with ./startzap.

This happened:

No complaints this time. Apache (or rather zap) fires up correctly, but when
I try to reach the server with netscape or lynx (http://localhost/, (I
changed port back to 80)) I get 'Document contains no data'.

Same goes for trying: http://localhost/cgi-bin/Zope/manage - I get 'zero
sized reply', 'The requested URL could not be retrived'.

Now - seems like there are some settings missing from the zap.conf file?

Or if nothings wrong - then maby give the readme-file a facelift and
make it more clear to ppl like me what to do to get it running.

Zope seems just too good to just let go!!

Hope to get it running soon

I just did a fresh install and this works for me.  Can you run bin/zap
by hand from the shell prompt?

Have you tried downloading a fresh copy of the Zap tarball?

Your own httpd binary might not be compiled properly for Zope use, check
out the Zap FAQ at http://www.zope.org/Community/Projects/Zap.  Doh, I
just noticed that this is not an obvious link from the d/l page.  I will
make it so.

The conf file that comes with zap is ok.  We and others tested it quite
a bit.

When we figure out your problem, it will get added to the docs.

Subject: [Zope] Is a JPython implemention within the realm of possibility?
Message-ID: <93C0BE6A6D6AD211BC7400A0C9D8FE87731223@exton1.bentley.com>

I am wondering if it is within the realm of possibility that the Zope
project might eventually support operation as a Java program (under JPython)
in addition to operation under traditional Python.  I know it would probably
be a large undertaking and that there may well be better places to spend
precious energy, but I thought I'd register my interest in the prospect.

In our case it is a given that a specialized JVM will be embedded in all of
our products and more and more of our own source will be written in Java, so
code which can integrate with Java easily is all the more interesting to us.
We already have a product which uses traditional Python behind a web server
to provide an entirely through-the-web user interface for product
configuration/administration. My aim has been to replace the traditional
Python with JPython since we'll have lot's of Java stuff we'll want to be
using on the server going forward anyway.  It looks like Zope would enable
us to do what we are already doing more easily (and therefore better). So
here's hoping we'll one day see Z-over-P-over-J.

Yeah.  I know it would have to be slower.

Zope looks cool.

I am not the expert about this, but: Zope is written entirely in Python,
except for a few 'kernel' like components written in C.  If you
translate these components into Java, you might just have something
there.  I'm not a Java guy so I have no real idea.

> Yeah.  I know it would have to be slower.

From what Ken was telling me JPython is actually quite well designed and
speedy, even for a Java program. :)  If you've commited yourself to Java
then I assume you've allready resigned yourself to the performance
penalty and are considering it in your engineering goals.  Performance
may not be your primary goal in the first place.

This was one of the things that I hoped to see by going Open Source.  So
far there have been ports to operating systems that we just wouldn't
have supported, which is a great to see.  I'm intrigued by someone that
really knows Java picking up a JZope effort.

As for Digital Creations, I doubt you'll see us focus on it unless one
of our consulting customers requires it.  Same old story -- never
enought time :^(

Subject: [Zope] Connecting Zope to Sybase: Linux or Irix ?
Message-ID: <199903011940.LAA18485@sam.engr.sgi.com>

I'm just beginning with Zope, and just beginning with a
project to develop some new software product management
(bug tracking and such) tools for use within Silicon
Graphics (SGI).

Zope appears to be an excellent fit for many of our
needs.

I will need to connect with an existing large Sybase
database (the existing bug data).

I can freely choose to use either Linux or Irix for
the server side operating system.

From which server O.S. would it be easiest to get Zope
connected to Sybase?  Something I read on www.zope.org
led me to suspect that I should use Irix, so that I
can use our Sybase licensed library, and that Linux
wouldn't work, because of a lack of the needed library.

Is that so?  Any other obvious factors that I should
consider in this choice?

Hmmm - I'm a slackware guy. And no glibc guy either....

Still the zap bin starts from the prompt and when I changed some settings in
zapctl then ./startzap also worked. That is the zap process shows on ps, but
I'm not able to connect to the server with any browsers.

Now - whats wrong?

My guess is that the hardest part of such an undertaking would be to
convert Jim's extensions to Java/JPython.  Specifically, ExtensionClasses
and Acquisition are probably the hardest to do (I believe many of the
others are just fast implementations of Python versions).  Jim Hugunin
mentioned that he had thought a bit about ExtensionClasses, but I'm not
sure how far that went. The efficient POS and other extensions are also
clearly a significant undertaking, but maybe not as hard to translate.

However, I don't see it happening until someone has a commercial
motivation to invest the large required number of hours into it.

Zope relies on a lot of code in C as well as Python, so I doubt you'll see
Zope on JPython anytime soon.

However, ZPublisher (Zope's ORB) could be made to work with JPython without
too much trouble. In fact a while ago I tried this and succeeded, though it
was quite slow. The main issue is that ZPublisher uses 'regex' while
JPython uses 're'.

FWIW, my shop is running Sybase OpenClient 11.1.1 on IRIX 6.2, 6.4, and 6.5
on a Challenge/S, O2000, and Challenge/L, respectively.  I successfully
installed ZSybaseDA into Zope on the Challenge/S; haven't tried on any others.

Also FWIW, I have experienced nothing but problems getting PCGI to work on
any of the IRIX platforms; your mileage may vary.

(Coincidentally, the company I work for owns a couple hundred SGI boxes and
we keep our inventory of them in a ZPublisher app...  it's on mySQL,
though, not Sybase.  OTOH, our request tracking system is a
ZPublisher-on-Sybase app.)

The last version I tried was the one distributed with Zope 1.9.0 - it
exhibited the same fail-on-process startup behavior as previous versions,
so I went to ZServer as a stopgap until I could complete a FastCGI
replacement.  I'm now using FastCGI, so it's no longer an issue.

Actually, some time ago I sent Jim some code that was a regex mockup
implemented using re.  It didn't do all of regex, but enough to make
DocumentTemplate work.

At first blush, I'd say that the host you've defined as the target of 
mailhost does not accept or is not running a mailer on port 25.

Are you certain you have mailhost setup correctly?

I Followed the URL backward from:
Michel Pelletier's "You've Not Mail !!!"  Page,  
http://starship.python.net:9673/crew/furtrapper/NotMail

Hey, this is neat,  starship.python.net must be 
running ZOPE because the port is "9673" !!!  
therefore going to:
http://starship.python.net:9673
"Welcome to Zope at the Starship Python!"

So, to join the crew of the Starship and get your own
ZOPE pages on the internet requires PSA membership.
One can join now and pay for a half year $50/yr 
or $25 for half.  Membership wouldn't be effective
until April 1st (a Foolish day!) 

So, Zope is cool and so is Python.  I am considering
joining PSA on the strength of Zope and Elegance
of Python but I'm concerned that Python doesn't seem 
to have much "MindShare" like Java or Perl.

Ok so our local Borders has only one book on Python:
"Programming Python" by Mark Lutz (Pub: O'Reilly)
A great book that is dated 1996.  The shelves are
full of books on Java and there are quite a few Perl books.

What is the BIG PICTURE here?  Is Python so good
that lot of programming tomes are unnecessary?

Why is there so little press on Python and so much
for the less Elegant and slower Java?

Is Python a "secret weapon"?  If so, the secret should
get out to the world so Python gets more mind share
and doesn't develop cobwebs.

***So, where are the rabid Python fans?***
Yes, a bunch of them are on the ZOPE list.

Great answers to these questions will only help ZOPE!

I'm using pcgi from 1.9.0 (README says it's 2.0a4) under Irix 5.3 (yes, I
know, I keep bugging the sysadmin to upgrade :) ).  Occaisionally, pcgi fails
to start up, logging "Interrupted system call  (116) unable to connect, fd=4".
I also had the same problem when using FastCGI w/ threads: the application
would hang and I'd get an "interrupted system call" in the log after a while.
I have never experienced either of these problems under linux, so might this
be an Irix problem?  I remember that Philip also suspected an Irix
"sockets-and-threads-don't-mix" problem, which appears to be what I have
experienced as well.  Philip, is theaded FastCGI still broken on Irix?

As a language qua language, Python is so good in design
and implementation that it has few dark mysteries that
require a lot of documentation to explain.

The existing Python books are quite good, with at
least 4 more in the works.  More Python books are 
necessary to explain things like Win32/COM programming, 
for instance, than the language itself.  Perl has
lots of books, because for the past 2 years, almost
anything that offered to make Perl programming easy
was given shelf space.  Java has lots of books
because almost everything in Java has to be written
in Java, and the Java libraries have been a moving
target for so long.

More important than the number of books (how many
Perl books do you really need, after the Camel?) is
the level of support/platforms in the Python community,
which is quite high.  It will probably never attain 
the proportion of mindshare that Perl or Java has,
but is has critical mass, and a lot of compentent people
who contribute code.  Too many companies now rely upon 
Python as their core development language for it to go 
away anytime soon.

More importantly:  You'll spend more time learning about
the eccentricities of whatever your environment demands,
be it Unix, Windows, web servers, CE devices, COM, Tk, etc.
than learning the language itself.  This is Python's 
great (and under-reported) strength.

Hi all,

This is probably more of a newbie Linux question than a newbie Zope
question, but I'm going to ask it here anyway:

I would like to connect Zope to a database, so I have setup both
PostgreSQL and MySQL. My reading tells me that MySQL is probably the
better choice as a web backend (Any comments from those of you more
knowledgable than I would be appreciated!) So I downloaded the MySQL
source, compiled, installed and tested it. It looks like I did it right.
I then downloaded the ZMySQLDA from the Zope site.

I have followed the directions--I think, but get the following error
when trying to do the initial make:

[tjg@puddleglum src]$ make -f Makefile.pre.in boot

FYI:  I know of at least 5 other Python-related book projects in various
stages of development.  One of those should be hitting those same shelves
in April sometime (http://www.oreilly.com/catalog/lpython/).  It even
mentions Zope in a couple of places.  [Disclosure: I'm a coauthor of said
book]

Python is certainly easier to learn than some other languages.

Mostly, because Java is backed by a multibillion dollar company with lots
of $$'s for public relations.

ObZope: I'm having a hard time with the 'access' file -- it looks as if my
Zope installation (w/ ZServer) only accesses the first entry in the file.
What am I missing?

A perfectly reasonable suggestion - and one that I have made many times myself!
<g>

I did, in fact, RTFM - but the FM makes absolutely zero mention of anything
"leverish", to adopt a seemingly Zopish mode of Englishish. ;-)  I followed your
link given in another message, and realised that what I had been reading about in
terms of Product Distributions was (I think) what you refer to as the "Lever".

IAC, I followed the instructions given, and when it didn't work I went back, and
worked my way through the Product Tutorial exercise - excellent!   The POLL
product works fine!  But the levered faq product .DAT file apparently failed to
unpickle - as described by others in this thread.  My product management screen
shows the FAQ product as installed, but the actual product directory still has
just the three files from the tarball.  In my case, however, it is on a Linux ZAP
system - so the problem is not confined to Win32 as others have conjectured.

Hope this helps, and apologies for the lack of specifics in my previous post.
Can we please have the term "lever" clarified and documented a little better.

My experience was MySQL had better support for large
streams of text data and blobs than PostgreSQL.  However,
MySQL also lacks support for transactions.  This probably
contributes to its speed, which in turn makes it popular
for web apps.

THis is completely correct.  The access file is ONLY for the
global-overall-uberuser :-)  Everything else should be defined in the

I assumed that the .DAT file contained all the component DTML and PY scripts etc
and that these would be expanded into the Product's home directory somehow.  Is
this not the case?  Is the .DAT distribution a way of  distributing the objects
without the source ? (more Cathedral than Bazaar)

Note that you could, pretty easily, write a new UserFolder type object
which worked off an access file. Could be useful for people who are generating
the access file from an /etc/passwd file, or whatever.

You could also skip the generation step and write a UserFolder which
works off of /etc/passwd.  In fact, NotMail could use this as a helper
too.

Subject: [Zope] ZServer and MSIE (long & detailed)
Message-ID: <l03130300b30112942a29@[206.40.158.77]>

Has anyone else experienced a problem getting Explorer to connect with
Zserver?  I have no problem with any version of Navigator but MSIE 3.01 and
4.0 and 4.5 for both Mac and Windows throw up an error box claiming an
"error with Explorer's internet extensions has failed".

Very baffling, I can connect just fine via telnet using the following
requests, ZServer (medusa) returns a proper html page.

Requests sent:

GET / HTTP/1.0
Connection: Keep-Alive
Host: www.fishwrapper.com
Accept: image/gif, image/jpeg, */*

response recieved:

blah, blah, blah.....

(note the difference in the sent host and recieved host, the host arg in
the start script sets the host for the ftp server, not the webserver...)

I can see nothing in the responses that would cause MSIE to fail, note this
has been tested from four different PC's on three different ip's, including
a local connection from my Lan.

Strangly enough I did a stream capture and hit my server and the startship
server (also running ZServer) and the two responses differ even though the
requests were from the same browser on the same connection.

Do starships ZServer and mine differ?

My  http_server.py  script carries RC_ID of:
 "v 1.4 1999/01/18 22:44:49 amos"  I downloaded a fresh copy of ZServer
when I grabbed the newest copy of Zope.

Any clues? I've been documenting and testing everything I could think of,
I'd report a bug but it seems MSIE works with the Starship server, so I
think it's not a bug so much as something wrong on my end?

Slackware V 3.6
Zope v 1.10.2
ZServer 1.0a2

I understand the security problems inherent in ExternalMethods; unfortunately,
without them, Zope is merely an "also-ran" in the web applicaton race, from my
perspective.  DTML in isolation is not an "ASP-killer."

I'm CC'ing the Zope list, in hopes that someone there can either allay or slay
our fears.

It seems to me that the security problem is that ExternalMethods can get access
to "sibling objects" of the object on which they are invoked, right?  I mean, if
we could make the siblings inaccessible, and acquired properties read-only, then
we should be ok, no?  Ugh, I don't grok acquisition well enough to tackle that
myself, I fear.

from inside DTML, is there a way to say "don't process any further DTML,
just return this to the user"?

What I'm looking at is a small DTML snippet that gets included at the
top of a number of pages, and looks for a particular variable to be
set. If it's not set, it should just display a small "please enter a
widget name" form which submits back to the same page, and not display 
the rest of the page at all.

will just doing a RESPONSE.redirect() automatically do this?

I'm making a Zope "Product" for managing and creating student surveys

couple of techniques:

1.	How does one enable a dtml file that is instantiated as in

	There's probably more to this - as at the moment the management
	screen goes straight to the "index_html" form as with the "Poll"
	Product.

2.	What's the approved way to catch database errors in methods?

	I'm creating tables on the fly, and need to check if the table
	exists before trying to create it. (I'd use a "tables" method if
	all the database interfaces supported it. I'd also use a try/except
	but the database objects have different names for their exceptions.)

Message-ID: <8174B1EE3D2CD21180960000F8056723CFB321@telisnt1020.is.tel.co.jp>

Hi All!

First off, I'd like to thank Digital Creations for an excellent (and
really fun) product. 

I'm building a prototype web site interface for a database where I
work using Zope 1.10.2 and the ZOracleDA product and have a some
questions. 

1. When trying to do a join (a lazy query, I know) like:

   select a.*, b.*
   from tablea a, tableb b
   where a.b_id=a.id

   Both tables have an ID column so Zope raises a 'ValueError'
   exception with the  message 'Duplicate column name, ID'.
   I wonder if instead of raising an exception something like the 
   following could be done?

   A diff of Shared/DC/ZRDB/Results.py:

120,131c120
<                 #raise ValueError, 'Duplicate column name, %s' % name
<
<                 #instead of error, append an extension to
<                 #create a unique name
<                 tempname=name
<                 nameext=1
<                 while schema.has_key(name):
<                     name=tempname+'_'+str(nameext)
<                     nameext=nameext+1
<
<                 #update with newly created name
<                 item['name']=name
---
>                 raise ValueError, 'Duplicate column name, %s' % name


   I tested this some and it seems to work. Are there any problems
   that could be caused by doing this?

2. I'll post the other questions separately because they are
unrelated. 


   TIA!,

The .DAT file only contains information to be added to the Object Database. It
won't be expanded into files onto your harddisk.

Zope stores all instances of classes in it's object databse, via a process
called 'pickling'. This, in simple terms, means that all data stored in an
object is turned into one stream of data that can be stored in a file.

As a 'Levered' product contains nothing but instances of classes, not the
classes themselves, it suffices to distribute only the compressed pickled
contents of the product. The source for the used classes you allready have (at
least with the FAQ you do, it uses only DTML Methods and Folders), and the DTML
scripts can be viewed in Zope, so you do get all the source.

The objects that make up the product should normally be automaticly
decompressed and imported into Zope, but the decrompressing seems to be
failing.

Thank you for pointing out how to fix this.  At first, the patch
didn't work with ZSQLMethods until I made a small change:

val wasn't set to None and so the null attribute never got used. Since
None is false, the above should be OK. (It seems to work for me,
anyway :^)

That works fine if it's all one big DTML method. But what if you have
a series of pages which each have
<!--#var check_widget_settings--> at the top.
inside check_widget_settings I want to be able to say "if this, then
enough. don't return back to the enclosing objects, just send what
you have now." kinda like a DTML exception :)

Subject: [Zope] AUTHENTICATED_USER
Message-ID: <153C1D93564@sahara.cspt.es>

Does anyone have any more information on AUTHENTICATED_USER? We saw a while 
back that it has properties (AUTHENTICATED_USER.has_role(['Manager', 
'Editor'])). I would like to be able to get the user name, and use that to 
index simple files for users. Is there something like 
AUTHENTICATED_USER['UserName']?? This is essentially the information that is 
returned if you try <!--#var AUTHENTICATED_USER-->. However, if you try 
something like <!--#if "AUTHENTICATED_USER in objectIds()"-->, it does not 
work.

The only way I have been able to use this information so far is to put 
<INPUT TYPE=hidden name=userID value="<!--#var AUTHENTICATED_USER-->">
in a form, and pass it in a REQUEST to another page. But I want to be able to 
get this information directly. I have even tried REQUEST.set('myUser', 
AUTHENTICATED_USER) inthe header, but this has the same problem 
(unsurprisingly) as AUTHENTICATED_USER itself.

Any hints?

Thanks,

JP

getting Zope to import that module.

2) I know I can put it in an external metod and use <!--var mymethod--> but it

AUTHENTICATED_USER itself is an object -- the reason
<!--#var AUTHENTICATED_USER--> gives you the user name
is that it effectively does an str() on the user object.

To work with the user name directly, you can use the
getUserName() method of the user object:

<!--#if "AUTHENTICATED_USER.getUserName() in objectIds()"-->

I am not sure I understand your problem. Default arguments can be given in
the definition of the function. If you need to pass a variable in an
external method you can just do
<!--# var "mymethod(myvariable)" -->
Additionally the self argument in the external method definition is
replaced by the object (or containing folder) that calls the method so you
have access to the namespace of the object through self.

Where is your function located? Is it an external method? In this
case imports in the method's file work fine, but only inside Zope's
search path (practically, the installation path and lib subdirectory).
A good place to put your modules and packages is the 
lib//shared/<your company> dir.

Use <!--#var expr="AUTHENTICATED_USER.getUserName()"-->

More hints linke this can be found in the User.py file in your
lib/python/AccessControl directory.

The following functions could be usefull:

getUserName(self): Return the username of a user
getRoles(self): Return the list of roles assigned to a user. 
getDomains(self): Return the list of domain restrictions for a user
allowed(self, parent, roles=None): Check wether the user has access to parent
hasRole(self, parent, roles=None): Check wether the user has the specified
roles
has_role(self, roles): Check wether the user has the specified roles

allowed & hasRole are one and the same. When called with parent=None, it
just returns wether the user has the named roles. has_role also checks for
roles, but doesn't automatically include the Anonymous role. So,
hasRole(None, 'Anonymous') always returns true, but has_role('Anonymous')
returns false for every user that has been authenticated.

Note that AUTHENTICATED_USER is always defined, also for anonymous access.

Here is a little example of what you could do with these functions:

<!--#comment-->Display user info<!--#/comment-->
You are the user named <!--#var expr="AUTHENTICATED_USER.getUserName()"-->.<P>

<!--#if "AUTHENTICATED_USER.getRoles()"-->
  You have the following roles:

  <!--#in "AUTHENTICATED_USER.getRoles()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You have no roles defined.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.getDomains()"-->
  You are allowed to log in from the following domains:

  <!--#in "AUTHENTICATED_USER.getDomains()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You can log in from any domain.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.has_role(['Manager'])"-->
You have the 'Manager' role.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['Anonymous'])"-->
You have the 'Anonymous' role. You are therefore an anonymous user.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['nonexistent'])"-->
You have the 'nonexistent' role.<BR>
<!--#/if-->
<!--#var standard_html_footer-->

The last call to has_role is to show that the user defined in the 'access'
file in the root folder of your Zope installation, has ALL roles, including
non-existent ones. And even more interesting, the call to getRoles() will
get you 'manage', a misspelled version of the 'Manager' role. This is
probably the only way to reliably recognize the superuser.

Well, it's actually deeper than that. You are correct in saying
that DTML alone is not an ASP-killer. Consider the similarities
between Zope and, for example, ASP/COM (though the same holds true
for practically any other system as well):

ASP lets you use the services provided by (COM) objects, which may 
be provided by the server or provided independently. I'm sure that
MS tries to make the server-provided objects fairly safe, but there
is _nothing_ stopping a programmer from writing and installing a COM
object with an evil() method that wipes out your C: drive, except the
fact that presumably the sysadmin exercises some control over making
these independent services available.

The same holds true for Zope (and any other app server out there). 
Like ASP/COM, External Methods give you the ability to provide more 
powerful services for use by your application. It also gives you 
exactly the same problems (though I'm sure that evil() method could 
be developed in a quarter of the time in Python :)

Basically, with power comes responsibility, and I can't really imagine
any system that could _safely_ allow possibly-untrusted people to write
(basically) arbitrary code. It's not even really a matter of what
services
are or are not available to those people. I'm sure that many, many hours

and much brain-power went into the design of Java's security mechanisms.
Even so, if I were a web site manager I still couldn't let untrusted
users write their own arbitrary java code to run in my web or app
server.
Even after I had figured out a way to wall off every service I could
think
of that could possibly be harmful, the user could still probably just do
the Java equivalent of:

  while 1:
    pass

Zope DTML goes to a good deal of trouble to minimize these problems 
in DTML itself, and we would certainly consider any concrete ideas
on how to make External Methods safer. Can you give me some examples
of other app servers that you feel deal with safety of external 
services in a better way? I'd be happy to do some looking into how
others are dealing with this.

Make your Product a Folderoid (zopespeak for a Folder Object) that
contains it's own user interface which the manager can edit.  Your

Folder.  Confera and NotMail both do this (Confera does it a little

There absolutely does need to be an "unprotected mode" available though - the
system designers might *need* it to do scary destructive things like deleting
files. Zope should not get in the way.

Zopistas

Seems that the activity on the Zope list has exploded. A lot of the
questions I read in the posts have been raised many times in the past. I
believe a FAQ on the Zope site is neccessary.

Do the folks at digital creations have time to set it up?

This is an excellent post.  I want to add that _getPassword() is a handy
function also if you want to use your Zope user to authenticate into an
external system, like POP3 or IMAP.

Hi,
The followowing problem seems very fundamental to me.
I already did a post to this group to this topic and I got the following
answer:

On Wed, 13 Jan 1999, Dr. Armin Tschammer wrote:

The "print" goes directly to the webserver, which confused it: it
expects
HTTP headers like "HTTP/1.0 200 Okay".

The "return" sends your data to *Zope*, which then does the header stuff

for you.  Same with cookies, content-type, etc.

Summary: dont use 'print', or redirect stdout to a log file.


Now the problem is deeper, what shall I do when I am import C++ Modules
in Python ( extending Python),
and that modules are writing to the stdout via "cout" or "printf", I
have no influence to that.


If I change the stdout via "freopen( "file, "wr", stdout )" or stuff
like that, I have no chance to switch back
to the *real* stdout  ( look at the c-faq of comp.lang.c ), and I *have
to* switch back because of the cgi-mechnism,
which uses ZPublisher.
The only the chance to handle stuff like that is to work with two
processes in the Zopemechanism.
A Zopeserver which tells the Zope Client to start a pythonfunction. Now
all stdout happens on the
client and the server listen for a string on a socket ( or something
similar ). Now when
the server gets the string it does all necessary wrapping ( content-type
and so on ), and
send it to the Xserver via its stdout.

Or is there a less complicate solution ?



 Thanks in advance

   Armin

That's unfortunate, but we understand.  Getting *anything* to work with
Apache's mod_rewrite module is quite a chore.  It doesn't help that
distributions like RedHat 5.2 ship it in a broken way, then people blame
us for it, then we track down a problem that is completely outside Zope.

Did you follow the recommendations to start with the built-in webserver
before trying integrate with Apache?  If so, did that work?

I believe this is allready under construction:
http://www.zope.org/Community/Services

By far from incomplete, but it is the right direction. I think Amos' FAQ tool
should be utilized there somewhere, and maybe some people from this list
willing to help out DC should fill it in, because it looks like Ken Manheimer
(who has been charged with community communications) allready seems overloaded.

What about

select *
    from tablea a, tableb b
    where a.b_id=a.id


Wouldn't this give you vars called a.id and b.id?

Hmmm... I bet Zope won't like that.

It occurs to me that a DTML document could contain this in a transparent
sendmail form, assuming there is already a handy Mailhost set up, to capture
and mail off the password of anyone browsing the page...

Not really -- you can't access _getPassword() from DTML. You would
have to write an external method to do that (which implies that
you have access to the filesystem, and could get the passwords
anyway if you wanted them that bad...)

While we are on the subject of AUTHENTICATED_USER, I would like my users to
be able to "logout" so that they then become anonymous again.

Any ideas?

I have seen this on Dejanews. It would be useful so that authorized users
don't leave themselves logged in if they don't quit Netscape.

	Is there any chance that you're trying to do something
	like:

	select *
	from a, b
	where a.b_id = b.id
                       ^

More generally speaking, we should be organizing the Zope documentation
project. There was word of it before, but haven't heard much on it
recently. In fact, the messages that I can find in my mailbox on it is
people saying we should start such a project :). I'd obviously be very
useful.

As an example: I myself have sent some (obscure) questions to the list
the week before last, and have only managed to receive an answer that
confused me more (I welcomed the answer though, of course!). I sent more
questions and observations last week, but haven't received answers yet
(perhaps it's because I'm doing something fundamentally wrong with Zope
but I'd like to hear it if that's so). Of course I'd like to see my
questions answered.

A FAQ would help filter out all the less obscure questions so that my
obscure questions might get answers. :)

So, the Zope Communication Project (hereby started if it doesn't exist
yet, this is open source after all :) should make its first priority to
create a fairly exhaustive FAQ. I currently have some time to invest in
the ZDP (he said, tempting fate; work's slow right now, but this can
change quickly).

Anyway, I'll help. If only with the *questions* side of the FAQ,
perhaps, but I can help. :)

Initial Plan of Action for the ZDP:

- Produce a fairly exhaustive FAQ, mining the mailing list for good
questions and answers.

- Organize the ZDP itself. :)

Regards,

Martijn

Message-ID: <36DC17B8.7F5CFF6A@pop.vet.uu.nl>

Hi there,

Hereby I announce in absolute adhoc anarchistic fashion the Zope
Documentation Project. The Zope Documentation Project aims to generate
documention on anything Zope.

The Zope Documentation Project needs people who wants to help. It needs
these people to get organized.

To get focused, I propose the ZDP's initial project is to provide FAQs
on various Zope topics. We can mine the mailing list for good questions
and answers.

The ZDP asks everybody to contribute. Right now we need everything. :)
We need questions and answers, and we need to categorize these in
separate FAQ sections. We need Zope webspace somewhere to put up the
FAQ, I assume using the FAQ product. We need to develop the FAQ product
further, if necessary. We need whatever you can think of.

The prime mean of communications for the ZDP is the Zope mailing list,
until further notice. I suggest that to keep the mailing list somewhat
organized we prepend our mailing list subjects with '[ZDP]'. If somebody
has a better way, we'll do it a better way.

Note that while I'm sending out this message, I'm not anything official.
I'm just attempting to get the ball rolling.

*nudges the ball*

Martijn

Could it be a 1.5.1 vs 1.5.2b2 thing?  I have 1.5.1 and it failed for me.
Is the zlib.pyd in 1.5.2 based on a newer version of the zlib library that
may not be forward compatible?

I don't have any experience with Zope or even Python, but am I right
in guessing that this looks like a problem with the python binary and
not with Zope?  Any ideas to precisely what the problem might be?

python is v1.5.1.
C compiler used is gcc 2.7.2.x.

I finally got it working - just couldn't get it off my mind. Was kinda
mindblowing the whole thing but finally - YES I MADE IT! :)

What I did was to jump off the mod_rewrite thing and try let apache handle
the authentication all together. At first I didn't know of the htpasswd
binary (stupid as I am) so things didn't work at first. Then htpasswd lit my
eyes - did the 'htpasswd -c' thing and ended up with a working AuthUserFile.
Now the trick was to configure the damned thing in httpd.conf - this worked
out ok:

"""
ScriptAlias /cgi-bin/ "/usr/local/apache/cgi-bin/"

<Directory "/usr/local/apache/cgi-bin">
	AllowOverride None
	Options FollowSymLinks ExecCGI
	Order allow, deny
	Allow from all
</Directory>

AddHandler cgi-script .cgi

<Location /cgi-bin/Zope/>
	AuthType Basic
	AuthName Zope-in
	AuthUserFile /usr/local/apache/conf/zope_auth
	require valid-user
</Location>

# 'zope_auth' created with htpasswd -c /usr/local/apache/conf/zope_auth \
'username'

"""

Actually - just like the manual tells me to. I did some wrong links and
generally fucked things up. Thanks for keeping me going at least (that goes
to all U ppl answering me) - sorry for taking up your time.

I discovered that my python binary was compiled without thread

Could the build script(s) check for proper thread support upon

Message-ID: <613145F79272D211914B0020AFF64019069109@GANDALF>

Hello everyone:

Some of you may know that many moons ago we (Brian) developed a plug-in
for Netscape Enterprise Server (ES) 2.x (and FastTrack -- based on the
same libraries) that addressed Netscape's nasty habit of removing
authenticated_user information from the environment before calling CGI
apps.  Obviously, this has a deleterious effect on interesting zope
applications.

Fortunately (?), we are up to our armpits in projects and initiatives.
As a result, we need someone to do a bit of work to upgrade the plug-in
from ES 2.x to ES 3.5.x.  I can provide the following files from our 2.x
incarnation:

o  plug-in source code
o  obj.conf
o  magnus.conf

The source code is only 153 lines of generously formatted C (w/lots of
defs) so I'm hopeful that this isn't a HUGE task.  I'm interested in
hearing quotes from people in the community that have experience with
the NSAPI and would, for a reasonable fee, develop, compile (Solaris 2.6
and NT4) and test an upgraded plug-in.  The work would be contributed
back under the ZPL.

Naturally, I'd also entertain offers from people to do this for free!
:^)

--Rob

P.S. - I KNOW there are some NSAPI wizards out there so don't be shy!

How about Mr. Creosote. This is a wonderful little utility from Jeff
Bauer. It basically an example implementation of socket datagrams... ie.
it lets you print out via a socket to a little server program. Its great
for debugging Zope/Bobo apps.

Here's Mr. Creosote's web page for more info...

Please don't ge me wrong:  I _like_ ExternalMethod / Product as a way to extend
Zope.  My comment is in the context of not (currently) being able to add
ExternalMethods to my Zope demesne on starship, given the (quite legitimate)
security concerns of the Zopemeister.

I looked at the ExternalMethod source last night a bit:  the actual method
execution is done via an apply() call, after loading and compiling the code for
the function.  We might be able to come up with an alternate product which used
a carefully tuned rexec() (Bastion?  I plead ignorance), operating on Python
code stored in the Zbase itself.

The particulars of my case are that the control structures of DTML are not quite
powerful enough to accomplish my task;  of course, strengthening them, even in a
"sandbox" model, still leaves open the possibility for buggy/malicious code to
do ugly things (like your example below).

Any Turing machine can do "while 1: pass", so no sufficiently general syntax is
"safe" from this attack.

Actually, the possibility which seemed most interesting was Doug Wyatt's
suggestion of "federating" a set of independent Zbases under one (at least
apparently one) server.  Then any damage my ExternalMethod did would be to the
Zbase would be on my own head, at least.  If that server were actually a process
running as me, then standard system security procedures should probably be fine.

You might want to consider switching to one of the official binary kits
available from MySQL's homepage. MySQL is notoriously picky about how it
is compiled.

Looks like you didn't install the development libraries for python
(python-devel or python-dev).

This was an idea I'd proffered, but honestly haven't looked at enough
yet to know whether it would work... it SHOULD work, but it might
require some modifications to the aquisition code, but I've not looked
neough yet.

Well, it might help if you offered what control strucuture you need, we
might be able to come up wit han interim solution.

TO me this is just a hack to get around it near term, and doesn't fix
the problem.  Also if you have 100 users, do you have 100 instances of
zope running under 1 ZServer?  That sounds like a true administrative
nightmare...  And substantial overkill.

Ok, the "teeth-cutting" example I am trying to implement generates math-facts
problems for my five year old.  In Python, two trivial functions:


I _think_ this one is easy in DTML:

    def problem( max_term, operators ) :
        """ Generate a single math-fact problem whose terms are within
            range( max_term + 1 ), using one of the supplied operators.
        """
        lhs = random.randrange( max_term + 1 )
        rhs = random.randrange( max_term + 1 )
        operation = operators[ random.randrange( len( operators ) ) ]
        return ( lhs, operation, rhs )

But not this one:

    def gen_problem( max_term, operators ) :
        """ Generate a math-fact problem whose terms and results are all within
            range( max_term ), using the supplied operators.
        """

        while 1 : # Arbitrary looping! (could benefit from
                  #   the dreaded assignment-in-conditional :)

            probStr = "%d %s %d" % problem( max_term, operators )
            result = eval( probStr )

            if 0 <= result and result <= max_term :
                return probStr

And of course, the DTML syntax for something like this is going to be ugly.

One instance per "sandbox", not one per user (although on starship this is a
distinction without a difference).  The "content manager only" applications will
do fine in a single Zope instance, as now.

In my experience many situations where external methods are needed do not
require access to the Zope data tree, like the math test example you
presented. 

One approach is to use a second server that does XML-RPC (Fredrik Lundh
has already written a client and a simple server) and set an
account/folder where everybody can upload their scripts and access them
through XML-RPC calls from their Zope environment. I suppose we can write
a product that provides the client site of the XML-RPC based on Fredrik's
implementation. As for the server site Jim once mentioned that the support
should go in ZPublisher but initially a simple server based on python
standard libraries will be adequate. Or use the newly released asyncore
libs though I suspect a multithreading server will be better in this
situation.

If however one requires access to the 'self' argument of an external
method such an approach will not be adequate. Usually though one can
collect the relevant parameters by using DTML calls and send them to the
XML-RPC server for processing.

Suggestion: for python-python data transfer and storage
XML-RPC is overkill.  Python already has marshal which will
be a lot faster and I think do the same thing.  Also, if you
haven't, please have a look at what I did using gadfly and cgi.
I know it's more conventional and hence boring, but nevertheless...

Message-ID: <016401be64f3$2e5b79d0$8725d2d1@rogue.jenkon-dev.com>

I have a folder with various boolean properties associated with it which are
accessed by the dtml docs as flags for enabling or disabling content.  Turn
off the flag and a chunk of the page goes away when it is next viewed.  This
works great, but I would like to associate that behaviour with the security
attributes.  In other words, when somebody in the Anonymous role is viewing
objects in the folder the properties should be unset, but when users in the
manager (or some other specific role) view the pages then the properties
should be set and those parts of the pages are activated.

How can this be done?

Thank you, Martijn, you've made my day!  This is extremely cool.  

As you might expect, here at digicool we're yearning to produce more and
better documentation, and, as with other things, we want to have more
time and energy to do it than we do.  This kind of effort from you, and
from anyone else who can help, is *severely* appreciated.  I know i'll

can, how else can digicool help?  Some thoughts, below...

Some thoughts:

 - We would be happy to provide a mailing list or two for you all

 - If it makes sense (logistically, for us as well as for you), we could
host 
   the FAQ stuff or whatever on zope.org.  This we'll have to discuss -
both
   what all might want, and what we can safely and effectively do...

(I've been thinking about requirements for a collaborative FAQ
mechanism, which can be tricky if you want it to be available for
contribution to the community in general, yet still remain organized
enough for people to find what they're seeking.  An interesting
problem...)

Zope's, I don't consider this a bug with ZServer but with MSIE as this also

Hm - this indicates you've upgraded your Python since the module
_pg was compiled (postgres?)
It's not the cause of the following error, but it is something you might
want to fix, anyway.

The error looks to be caused by ZopeHTTPServer not handling a client
aborting the connection. Looking into the code, at around line 240 of
ZopeHTTPServer/ZopeHTTPServer.py, the write() method of ResponseWriter
should probably trap IOError and ignore it. 
Something like wrapping the two calls to write() in the write method
like
  try:
      write....
  except IOError:
      pass

would be a blunt fix to it. I don't think DC want to continue to 
support ZopeHTTPServer, tho. You might want to try to upgrade to ZServer,
instead.

No, because from DTML you can't call methods starting with an underscore. This
was actually the reason I didn't include this in my overview.

You can still use it in en external method, I know. But then again, I can do a
heck of a lot more bad things in external methods.

This is very hard to do from the serverside. I can force a new login, but I
cannot stop a browser from authenticating itself at every request, therefore
effectivly becoming anonymous.

Problem is more that HTTP is stateless, a user is not 'still logged in', but it
autenticates itself at every request. Only when the server says that the
authentication is incorrect, does the browser ask for the username and
password.

What you could do, is write your own UserFolder/User combo, that stores a
last-access time on the User object, and checks for this every time a user is
authenticated. If the difference is greater than, say 15 minutes, you force a
reauthentication by raising a permission denied.

Just to show support, count me in. I allready started rewriting the

I tried playing with this once upon a time, but I found that the stupid
browser still cached the original result and would continue to use it after
the failed login/relogin combination. Most frustrating.

Subject: [Zope] need help with IIS/ODBC
Message-ID: <3.0.6.32.19990304173128.008fc510@hito.eccosys.com>

As a novice (who's loving Zope!) I'm having a terrible time trying to get
Zope1.10.2 on NT with IIS to connect to MS SQL with a Z ODBC connection.
Previously I had no problem getting Zope 1.9/ZopeHTTPServer to connect to
MS SQL via Z ODBC. 

Recently I upgraded to 1.10.2 without a hitch, and was able to run it with
IIS 4.0 after putting the (PCGI executable?) MYZOPE.exe in
/InetPub/scripts/ and turning off in IIS both Basic Authentication and NT
Challenge/Response as I read here in the list.

My problem now is that when I try to open my db connection (exactly the
same connection that was working with 1.9 & ZopeHTTPServer) I get the
following error from IIS:

>HTTP Error 400
>400 Bad Request
>Due to malformed syntax, the request could not be understood by 
>the server. The client should not repeat the request without modifications.

In trying to figure out what's going on I've noticed a couple things.
First, and I think most illustrative, if I try to add a new Z ODBC
connection, none of my ODBC sources are showing up in the available list
(except the default 'LocalServer, SQL Server') - whereas if I run my 1.9
Zope with ZopeHTTPServer all my ODBC connections show up just fine.

Also, running my new 1.10.2 Zope/IIS with the faulty db connection side by
side with the functioning 1.9/ZopeHTTPServer, I printed our the environment
variables of both and noticed some differences - USERPROFILE's are Default
User vs. Administrator, and the 1.9/ZopeHTTPServer contains variables not
contained in the 1.10.2/IIS environ: HOMEPATH, TEMP, USERNAME, HOMEDRIVE,
USERDOMAIN, PROMPT, LOGONSERVER, TMP. I attempted to set at least
USERDOMAIN in the 1.10.2/IIS environ, with no luck.

I've read all the posts from the list that I could find dealing with IIS
and ODBC, but couldn't find anything with info on this type of trouble.
Have I made a boneheaded mistake and started to look in the wrong places
for the fix? Any help/info/pointers would be hugely appreciated as I
continue to bang my head on my keyboard hoping that I'll soon clear this
hurdle and get back to having fun with Zope!

Thanks!

Jay

You could, using AUTHENTICATED_USER.has_role() and manage_changeProperties(). I
think it will be better if you completely skip the property setting though..

You could just show content using
<!--#if ATHENTICATED_USER.has_role(['Anonymous'])-->
        Content _only_ for the Anonymous user
<!--#/if-->
<!--#if ATHENTICATED_USER.has_role(['Manager'])-->
        Content for users with the Manager role.
<!--#/if-->

This way you don't accidently let any properties float around, causing content
to be shown to the wrong people.

You can use the #in tag's grouping features for this. If you use GROUP BY in
your SELECT statement, or use the appropriate sorting, you can use the
following DTML code to get the desired output, assuming the column names are
the same as in your example:

<!--#in MySQLMethod sort=field2-->
<!--#if first-field2-->
    <!--#var field2 fmt="DayOfWeek"-->, 
    <!--#var field2 fmt="Month"-->
    <!--#var field2 fmt="day"--><BR>
    <BLOCKQUOTE>
<!--#/if-->

<!--#var field1-->

<!--#if last-field2-->
    </BLOCKQUOTE>
<!--#/if-->

<!--#else-->
Sorry, no colors in your query.
<!--#/in-->

The variables first-xxx and last-xxx are set whenever the field with name xxx
starts/ends in a sequence. For more information on this, read the Zope DTML
User's Guide (http://www.zope.org/Documentation/Guides/DTML

Subject: [Zope] ZPublisher and creating children
Message-ID: <36DCF9B5.97A62E66@acriter.com>

Hi,

I'm using ZPublisher+DocumentTemplate+BoboPOS in a cgi environment,
because that's all I need (and can use on my ISP's box). In the couple
of things I've developed so far, a pattern has emerged that disturbs me:
if you have a container object, when adding a child, the whole add thing
is done in the parent. IIIRC, I fetched this design from the (Bobo)
Trinkets example when I started:

class Container....
     add = HTMLFile(....)
     def do_add(self, childattrone, childattrtwo, childattrthree):
        d = self._items
        d[childattrone] = Child(childattrone, childattrtwo,
childattrthree)
        self._items = d

class Child...

     def __init__(self, childattrone, childattrtwo, childattrthree):
         ....

     edit = HTMLFile(....)
     def do_edit(self, childattrone, childattrtwo, childattrthree):
           ....

The Container, IMHO, "knows" too much about the Child in this case, and
it's hard to modify the attribute set of the Child class. Am I doing
something wrong? Is there a design pattern here I'm not aware of?

Regards,

Cees

I have exactly the same problem with an Access database, same error. I'll file

These are good ideas (and thanks Chris for the offer!), but Ken
Manheimer later on in the list is offering space on www.zope.org, and
that would of course be perfect.

Thanks again though!

It was getting obvious that this was so. You guys all did a great job,
and still are doing a great job, but the volume of questions and
documention requests has exploded in the mean time. Which is great, in
fact, of course, as it shows people are interested.

This would be great! We probably don't want to be spread out too much so
one mailing list would be best (zdp@zope.org?). I also intend to make
regular announcements of ZDP's progress (and some advertising to get
people more involved in the project) on the main Zope list (or future
multiple main Zope lists :).

Right now though to keep the ball rolling I'll be using the normal list
to send out messages.

Zope.org would I think be the ZDP's favorite place to be hosted on, so
that'd be very nice. Your thoughts on how we could best arrange this
(who gets manage access to the place, if we develop in a branch we
export to you, or develop in there directly, or use FTP, or possibly
something else, etc) are welcome.

Independently (for local purposes) I've been thinking about making a FAQ
wizard product myself, but I got stranded somewhere in the beginning (my
laments I posted some time ago to the list :). But at least I've given
some thought to the design. Now Amos made one, and we can build on that.

The use of the tree tag is nice, but probably a simple list is more
useful in some cases (one can do a text search in it, for instance).
From my cursory glance at the management screens of the example, it
seems that it's not hard to produce that.

What would also be nice is some way to simply generate plain ascii text
versions of the FAQ as well, along with possibly some other versions. We
could also think about generating DocBook SGML (which then can be
converted in a lot of different formats with for instance the Linux
SGMLtools 2.0).

I haven't given too much thought to collaboration mechanisms. It would
be useful to have the ability to easily move questions around in the
list from one section to the other. My plan is to early on just get any
question/answer pairs we can come up with (from mining the mailing list,
documentation, and whatever people contribute). Later on we can then
organize these in categories, once the pattern becomes clear (likely
we'd have a DMTL section, for instance, and an installation section). If
there's flexibility in moving questions around the FAQ might be
developed more quickly. 

People could contribute question/answer pairs (or just questions) in
some 'contribution area' and the managers of the list can then edit
these and move them to the right sections of the list after doing so.
The contribution area should still be visible for everybody, so that
even the raw entries can be useful. I'm brainstorming right now, so
here's another idea: if someone sees a question in the 'contributed'
area that he knows the answer to, that person should be able to write in
an answer. Even with the already edited questions in the main list it
would be useful if people could leave comments ("I tried this but it
didn't work for such and such reason. But if I did this and that, I got
it working."). The editors can then later review all that's added and
integrate it into the main text.

Right now I intend to just assemble a big raw plaintext file (structured
text!), though; anyone can work with these. It's good to keep the
process moving.

Martijn

As long as the *me too!* message doesn't include the entire previous

I have no DNS, it's a local system only. I'm using Windows 95 and this

Subject: [Zope] count of items in group?
Message-ID: <XFMail.990303130130.julian@zereau.net>

Using the "in" tag's grouping capability, is there any way to get the count of
items in that group? I need this so I can have a table with one row per item
and a cell rowspanned for all the group's items (eg: related products and their
picture).

Subject: [Zope] Strange problem calling a base classes method
Message-ID: <01E40461E003D21195CC0080296495D80B12B3@gates.cdc-group.com>

While debugging a Product that inherits from OFS.Folder stumbled across
the following problem (copied from the debugger command line stopped
inside one of my Product's methods):

>>> self.__class__.__bases__[0].__bases__[3].__bases__[1]
<class OFS.CopySupport.CopySource at 8d11e0>

>>> isinstance (self, OFS.CopySupport.CopySource)
0

>>> (self.__class__.__bases__[0].__bases__[3].__bases__[1] 
     is OFS.CopySupport.CopySource)
1

The first line says self is an instance of OFS.CopySupport.CopySource,
the second says it's not. The class objects are identical.

My problem is that I'm not able to override one of 
OFS.CopySupport.CopySource's methods and to call the
base classes method from inside. At that point I get
a 
    TypeError: unbound method must be called with 
               class instance 1st argument

which usually occurs when calling an unbound method with
an instance of the wrong class.

I'm clueless..

No, there isn't. You will have to use the SQL statement, to add a calculated
value column to it's output. You should be able to use COUNT to achieve this.

Actually this example shows the beauty of Zope/Bobo programming -- the
code looks completely like normal Python code, no CGI hackery involved.

Anyway, this is really a Python question, IMO.  You don't the arguments
to the Child's constructor to be hardwired in the Parent, right?

You could take a route where pass a dictionary, e.g. REQUEST, into the
Child's constructor and let it figure out for itself what it needs.
This feels less OO and doesn't let Zope/Bobo help you with type
conversions and raising exceptions for missing arguments.

Good timing.  We are planning a Collector Day At The Beach pizza party
on Friday.  We'll gather everybody together for a couple of hours,
discuss a bunch of submitted issues, and try to clear them out.  I'll
articulate a policy on support within a week.

We still haven't emerged from our network hell -- our dedicated line
hasn't been installed yet -- but things are slowing getting under
control.

Count me in as well.  I'm meeting with some folks today to get a Zope
training course scheduled.  I'll create the preliminary docs which they
will improve and use for the course.  Thus I'll have some some material
for a (perhaps four day) training course to contribute.

BTW, is there any interest here in a Zope training course?

Subject: [Zope] [ZDP] Assorted FAQs
Message-ID: <36DD3FD7.F71EAE80@pop.vet.uu.nl>

Hi everybody,

Here is a start. I just randomly browsed the mailing list and created a
completely uncategorized set of questions and answers for the FAQ. I
even snuck in a question of myself, see if you can answer it. :)

If you see a problem with some of these questions or answers, send a
followup with suggested corrections to the list and I'll include them in
the FAQ. If you have more question/answer pairs, go ahead and followup
too. I prefer these things to appear in the list (in a thread, and
marked by [ZDP]) for now, as this might stop people from writing the
same FAQs twice. I hope in a while we'll get somekind of collaborative
FAQ environment going that makes all this easier.

I'd prefer additions to the FAQ in StructuredText for now. See what
follows for an example of the format I have in mind. If you think
another format works better feel free to convert. (yes, that's the theme
of open source; if you want something done differently, feel free to do
the work to change it :).

Here's what I have so far, enjoy!

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use:

        &lt!--#var "external_method_name(arguments)"--&gt
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is:

        &lt!--#var expr="external_method_name(arguments)"--&gt

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

Well, the underlying issue is the stateless-ness of the whole thing. In
normal python, you'd create an empty child, call the child's editing form
so the user can enter initial data, and only after the user's commit add
the child to the container:

def addChild(self):
     newChild = Child()
     if newChild.editForm() == true:
        container.append(newChild)

in short. I've attempted this in the ZPublisher environment, but to no
avail - either it didn't work at all or it got very messy (with the Child
needing to know about the Parent, etcetera).

I must say, I was under a bit of time pressure last night when looking for
alternatives (wanted to have a beta release on my website before
breakfast), I haven't got around playing with hidden form variables
etcetera yet - that could work. Just hoped somebody on the list here would
have a canned answer - I'm a lazy guy ;-)

Subject: [Zope] Some tough questions about zope... (long)
Message-ID: <v0410440eb302e9edd947@[128.240.198.13]>

Hi all,
This is quite a long email where I ask a lot of questions about Zope, 
but I hope you'll be lenient with me as I think I have a few hard 
decisions to make!

Some background:
I'm one of the web developers here, with a remit to implement a 
curriculum database that can;
(a) support the Medical Faculty here
(b) get rolled out to three other Medical-related sites, each with 
their own 'look and feel'
(c) possibly implement a University-wide curriculum database.

The curriculum database is essentially delivering online study guides 
(over 100 for each Faculty) whose source is originally from very well 
marked up Word Documents. In addition, we include multiple choice 
questions, file upload of lecture notes etc. and some 'active' web 
pages showing dynamical processes in medicine etc. The curriculum 
database needs to be searchable across its entire breadth (although 
initially restricted to the one site), so that students and faculty 
can find occurences of, say, 'lung cancer' in lecture resources - 
this is to plan for curriculum management, so that we can find out if 
we're pushing subjects too much (or indeed, whether we're pushing a 
subject at all!). We have other applications (nearly all of which are 
written in Perl/PHP3) and want to seemlessly integrate them into the 
curriculum database.

Currently we do all our development work on Unix, using Apache 
virtual web servers, MySQL as our database engine and Perl running as 
a CGI for most of our applications. My input has been to introduce 
PHP-3 (an Apache module with a bulit-in XML parser) and some XML 
knowledge to the group. I've been looking at a scenario where our 
study guides are converted in XML using Omnimark and held as static 
XML documents in a database. They are then rendered into HTML/RTF and 
put into static web directories. The student can run a program that 
extracts elements from selected XML documents and creates a 
customised set of HTML pages or RTF document that is built for them 
'on the fly'. My manager was a bit worried about all these static 
pages lying about and to be honest so am I, but extracting the 
relevant XML from a database to render into individual HTML pages 
seems a massive drain on the system.

I found out about Zope Monday morning, dl'ed it, installed it, got 
one or two things working... and have been worried sick ever since.

My problem? is that I can see how Zope can do so much for us, but it 
seems to need a hell of a gut-wrench to do so.
There also doesn't seem to be an easy 'half-way' house to move to Zope.
I've read a lot of the documentation, and am doing so constantly, but 
the wisdom of the list would be very helpful indeed.

The questions:
a) Is there a way for us to 'dump' the non-dynamic parts of a Zope 
database into static HTML pages. This would act as a way to say to 
the team "look, we have a parachute!".
b) Can I integrate with the Perl/PHP3 programs that we have (the Perl 
programs are mainly .cgi, but the PHP3 programs are server-side 
scripted, and as such are embedded into the HTML itself). This is so 
that I can
c) Is there any way of using the XML documents that I'm creating into 
the database and parsing them to produce either HTML or RTF output?
d) I know that this a terrible question to ask... but is Zope likely 
to 'remain' open-source (we're worried about getting stuck with a 
proprietary system)?.
e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
dropping the :port requirment).
f) I'd like to have the option to have user authentication 
information coming from a database - is this possible?
g) We have something like 200 main level directories holding the 
study guides, each with up to 200 files in them - is that pushing the 
Zope database too far?
h) We also need resources such as QuickTime movies, images PowerPoint 
slides etc. to be uploaded - would they sit in the database or can 
they be held somewhere else (and what happens about file name 
conflicts)?
i) Does Zope have the equivalent of 'server logs', which we use for research.
j) Is it possible to have a 'pointer' at a location in the Zope 
database that will point to a 'real, honest to goodness' HTML file on 
the server (ie something like a redirect..oops I think I may have 
answered my own question)
and lastly
k) What kind of loads have people put Zope under (10,000 +hits a day, 
100k?). We have one application which has 170 Medical Students 
sitting in front of screens and clicking a button at the same time 
(they're selecting their final year options) which then starts 170 
CGI-based Perl processes off interrogating and updating the database. 
This really grinds the system down...

I hope that I haven't bored everyone to tears here - it's just that 
Zope seems to do an awful lot of what I need, and I'd really like to 
know what I'm letting myself in for if I start using it for 
everything I do....

many many thanks,
tone.

Cookies or passing around secret messages would be the way to avoid
this, don't use Basic authentication at all.  The UserDB product shows
off a User Folder than uses cookies, and possibly today I am releasing a
User Folder product that authenticates off of a flat file, like
/etc/passwd for alpha testing which also uses either Basic or Cookie
auth.  If you use Cookie auth you are presented with a login/logout
screen to set/clear the cookie.

Message-ID: <199903031517.HAA31270@hipmail1.gohip.com>

Thanks for the help, but...

My problem is a little bit harder than that. The data in field2 is date *and* 
time. So like this:

field1 field2
------ ---------------
red    3/1/99 10:00 AM
blue   3/1/99 11:00 AM
green  3/1/99 03:00 PM
brown  3/2/99 10:00 AM
yellow 3/2/99 04:30 PM

I've seen in the guide where you can format a data field when outputting, but 
how do actually extract the day-of-the-month number and put it in a temp 
variable. The pseudo-code I've used before to do this before is:

tempday = 0
for each record
  if tempday<>dayofmonth(datefield) then
     print out a header
  print out other fields
  tempday = dayofmonth(datefield)
next

I'm just having a little trouble translating that into DTML. Creating a simple 
temporary variable seems overly complicated.

This begs the question we've asked around here so many times, 'What is
data?'  Everything in Zope is Dynamic, in my thoughs, 'non-dynamic' is a
Document with not DTML in it.  But there is no way for Zope to sniff a
document and see if it contains dynamic structures or not.  Perhaps what
could be done is to write a simple MyDocument that you stipulate in
policy never to have dynamic stuff in it, and then write a crawler
scripts that sucks out all such documents into a local file structure.
There maybe easier solutions.

...do what? ;)  Zope can call your cgi scripts just like they are, as
URLs.  They would, of course, have to be external to Zope and if you
have a bunch of little ones you may find it better (and a damn sight
easier) to rewrite them as Python in Zope as external methods. (DTML is
also a rather powerful language for being so simple).  Just leave your
PHP stuff in your documents; Zope will parse out the DTML and return it
to the server, which will parse out the PHP stuff and return it to the
browser.  In fact, you can probably make DTML and PHP work together
nicely and simplify much of your PHP code.  In the quickie case you
don't need to change your PHP.

Zope doesn't contain an XML parser.  You would need to do this with an
external package.

Yes.

Yes.  There is an unsupported open source User Folder Product called
UserDB, where you tell it how to query your DB and it uses that for
authentication.

Not at all.

ooo.  Someone has yet to write an ExternalFile product (though I suspect
it would be fairly simple) to add objects to the db that refer to files
outside the db.  For now you can upload them as File objects to be
contained entirely in the db.  The same rules that apply to file name
conflicts in, say, a UNIX filesystem, apply to the Zope db.  You can't
have the same object id in the same folder. (With a minor non-exception
of aquisition, all lower folders can see the contents of higher folders,
but if you place an object in a lower folder with the same id as an
object in a higher folder the lower object will override the higher
object.  Get that?)

Since Zope is served through a web server you can continue to use the
server logs.  In other words, No. ;)  Object by Object logging is
something we've discussed, but would require *a lot* of thought and
work.

If that file is being served up by Apache then you can just use it's URL
as a 'pointer'.

Ah yes, the inevitable benchmarking question.  There are lots of issues
here, memory footprint vs processor speed vs concurrent access...etc.
The quick word is, Zope is fast and it will get much faster.  Zope is
currently not concurrent but will be in 2.0.  Zope+Apache is a bit slow
due to the pcgi bottleneck and is much improved by using ZServer.  As it
stands now, ZServer is something like twice to 10 times faster than
Zope+Apache.  Medusa (the web core of ZServer) serializes the requests
into Zope at the moment, but when 2.0 comes out it will be the fastest
web application platform on earth.  Don't quote me.

Let me try to answer (some) of your questions:

>The questions:

I will be looking into this, as soon as I have the time. The answer for now is:
probably, because everyone wants to download a local copy of part of any
website at some point. There are tools out there to do this, I haven't looked
for them yet.

>b) Can I integrate with the Perl/PHP3 programs that we have (the Perl

Just run Zope via Apache (see below).

>c) Is there any way of using the XML documents that I'm creating into 
>the database and parsing them to produce either HTML or RTF output?

Python is very capable of parsing XML. You will have to write an External
Method to handle this, though. An example of XML parsing can be found at
http://www.zope.org/Download/Contrib/XMLConfig.tar.gz. This Zope Product parses
a static XML file for use in Zope.

>d) I know that this a terrible question to ask... but is Zope likely 
>to 'remain' open-source (we're worried about getting stuck with a 
>proprietary system)?.

I certainly do hope so. I intent to use it en expand on it heavily anyway, and
sodo others. These extensions will generally be Open Source themselves, making
it hard for Digital Creations to pull Zope out of the Open Source domain.

>e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
>dropping the :port requirment).

Yes. The doc/WEBSERVER.txt will start you on this. Be warned though, there are
some problems with Apache and Zope integration, for reasons that others are
better equiped to explain.

>f) I'd like to have the option to have user authentication 
>information coming from a database - is this possible?

Yes, you can find the UserDB Product at
http://www.zope.org/Download/Prereleases/UserDB/UserDb-1.2.0-nonbin.tar.gz.

>g) We have something like 200 main level directories holding the

Nah, Zope has handled much more than that allready. Ask Paul =).

>h) We also need resources such as QuickTime movies, images PowerPoint 
>slides etc. to be uploaded - would they sit in the database or can

>conflicts)?

Zope can store any filetype you want it to. Filename conflicts are handled the
same way a filesystem handles them: In the same Folder, you cannot have two
objects with the same name at once. But because it is a hierachical system, you
can use the same name in two different folders.

>i) Does Zope have the equivalent of 'server logs', which we use for research.

ZopeHTTPServer's output is it's serverlog. You can start it up with STDOUT
redirected into a file. When you use Apache as your webserver, all requests
will be logged through Apache itself.

You said it yourself =).

Zope will be much much faster. I can't give you any direct numbers, maybe
someone else on this list can. You basicly don't have the overhead of starting
a fullblown new process for every request, and Zope pools Database connectiosn
for you, so you don't have the initial connection overhead either. And, your
code isn't compiled everytime, like with Perl.

I know the feeling. I was choosing between ColdFusion and Zope for
developing my new application and had some similar questions. Ultimately,
I chose Zope.

[nice application description deleted]

Right now, there isn't. This question has come up repeatedly on the list,
to the point where DC is getting sick of hearing it and thinking of actually
implementing something :)

They have said it would be pretty easy, and I believe it. I think 
the basic idea is to write a method that will go through the Folders and
use the DocumentTemplate code to render out the pages.

If you're using Zope with Apache, you use mod_rewrite to get the
authentication headers passed to Zope. You can also use mod_rewrite to
decide how URLs map to content on your server. For example, you can
have all of the content on your site go through your Zope.cgi, but
/cgi-bin/* can go directly to your CGI or PHP files. You can access
MySQL from Zope, PHP and Perl, so they can all use the same data
source for the databases.

| c) Is there any way of using the XML documents that I'm creating into 
| the database and parsing them to produce either HTML or RTF output?

I'll leave this one to people more knowledgeable about XML.

| d) I know that this a terrible question to ask... but is Zope likely 
| to 'remain' open-source (we're worried about getting stuck with a 
| proprietary system)?.

I think it would be tough for DC to try to take it back at this point :)
Even if DC did decide to not release any more updates to Zope, the community
would probably continue working from the 1.10.2 code. Anyhow, DC had
sound business reasons to release Zope as Open Source. Over time, they
will likely get a lot of benefits by having done so and by encouraging
outsiders (like us) to work with and improve Zope.

| e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
| dropping the :port requirment).

Yes. This uses a technique called Persistent CGI. It works quite well.
There is also a hope that there will be better integration with Apache
in the future. Also, as ZServer stabilizes, you may find good reason to
migrate from Apache to it.

| f) I'd like to have the option to have user authentication 
| information coming from a database - is this possible?

There is an unsupported bit of code called UserDB which is designed for
this.

| g) We have something like 200 main level directories holding the 
| study guides, each with up to 200 files in them - is that pushing the 
| Zope database too far?

Though I have no first hand experience with a Zope DB this large, the
DC guys have said that they've worked with some very large DBs.

| h) We also need resources such as QuickTime movies, images PowerPoint 
| slides etc. to be uploaded - would they sit in the database or can 
| they be held somewhere else (and what happens about file name 
| conflicts)?

You could put them in either place. There would probably be some
advantages to putting them in the database. For example, your standard
Zope security rules will apply to the downloading and updating of the
files.

| i) Does Zope have the equivalent of 'server logs', which we use for research.

I don't know about ZServer, but if you use Apache as your web server you
will be able to use your standard server logs.

| j) Is it possible to have a 'pointer' at a location in the Zope 
| database that will point to a 'real, honest to goodness' HTML file on 
| the server (ie something like a redirect..oops I think I may have

Yes, you can do a redirect.

| and lastly
| k) What kind of loads have people put Zope under (10,000 +hits a day, 
| 100k?). We have one application which has 170 Medical Students

| CGI-based Perl processes off interrogating and updating the database. 
| This really grinds the system down...

I've heard it said that Zope should be able to handle 500k hits or more
on reasonable hardware. Of course, this depends on exactly what the
server has to go through for each of those hits, etc. DC is also working
on concurrency for Zope 2.0. This will probably enable you to handle a
whole bunch of requests.

Good luck!

You'll have to use SQL function for this. In MySQL you could do the following:
SELECT field1, DATE_FORMAT(field2, "W, M d") as datefield FROM MyDB.

Put this in a Z SQL Method, and then the following DTML will get you your
results:
<!--#in MySQLMethod sort=datefield-->
  <!--#if first-datefield-->
    <!--#var datefield-->, 
    <BLOCKQUOTE>
  <!--#/if-->

  <!--#var field1-->

  <!--#if last-datefield-->
    </BLOCKQUOTE>
  <!--#/if-->

<!--#else-->
  Sorry, no colors in your query.

Everybody on this list is lazy ;-)

This is my approach:
First define a Webobject class that every object needs to inherit. The
simplest could be just:

class WebObject:
	        
    def __init__(self,name):
        '''__init__(self,name)
        '''
        
        self.name=string.replace(name,' ','_')

    def _set_root(self,root_obj,parent_path):
        '''_set_root(self,root_obj,parent_path)

        sets the root object and relative path. Note: 
	one will never need to pass parent_path directly. I also need
	to have a reference to the root object so I can do stuff remotely
	similar to acquisition'''

        self.root=root_obj
        self.rel_path=parent_path+self.name+os.sep

class Container(WebObject):

    def __init__(self,name):
        WebObject.__init__(self,name)
        ##Holds contents
        self._d={}

    def __getitem__(self, key): return self._d[key]

    def items(self): return self._d.items()

    def _do_add(self,object):
        '''_do_add(self,object)

        Adds object in container. Object MUST have inherited the
        WebObject class.'''

        name=object.name
        if hasattr(self,name) or self._d.has_key(name):
            raise ValueError,'Object with same name exists in WebFolder'
        d=self._d
        object._set_root(self.root,self.rel_path)

        d[name]=object
        self._d=d

So you can create any object that has inherited the WebObject class
independently and add it to the container instance.

Subject: [Zope] [ZDP] Tree FAQs
In-Reply-To: <36DD3FD7.F71EAE80@pop.vet.uu.nl>
Message-ID: <4.1.19990303153836.00a64c50@lisp.atmm.nl>

My two cents on the tree tag:

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute of
    the tree tag. The objectValues function of a folder returns all objects
    contained by that folder. 

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML 
    Document objects in a Folder. Other metatypes you could select on are:
    Folder, DTML Method, File, Image, Mail Host, User Folder and Session.
    This is not a complete list, as Products can and will define their own
    metatypes. If you want to show more types, just add them to the list,
    like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        &lt;!--#tree branches_expr="objectValues(['Folder'])"--&gt;
	    &lt;A HREF="&lt;!--#var URL1--&gt;/&lt;!--#var id--&gt;"&gt;
            &lt;!--#var title_or_id--&gt;
            &lt;/A&gt;
	&lt;!--#/tree--&gt;

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a tree, is
    called with ?expand_all=1, the tree tag will expand all it's branches.
    Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand 'buttons'::

        &lt;A HREF="&lt;!--#var URL0--&gt;?expand_all=1"&gt;
          Expand all&lt;/A&gt;|
        &lt;A HREF="&lt;!--#var URL0--&gt;?collapse_all=1"&gt;
          Collapse all&lt;/A&gt;

        &lt;!--#tree--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        &lt;!--#tree single--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;


More cents will follow.

Martijn

SQL methods
patches/hacks to Zope

This sounds like something we need.
I know that I could use it.
If folks will critique this design, I'll implement it.

- - Proposed Access Method - -
It is desired to be able to have "non DTML" files incorporated
in a Zope URL system. These files might be static GIF files,
quicktime movies, or just plain old HTML.

Obviously, they might be "included" in a DTML page by simply
referencing them directly by their URL. However, I can see cases
where one would like the access to be under the control of the Zope
system.

For example, access controls might apply.

I believe that we can achieve this by having an object
which represents an ExternalFS mount point.

In general, we map a URL onto a node of the FS.
It would be directly analogous to a symbolic link (ln -s).

The Zope mount point would enforce permissions just as if the
file were loaded into the Zope DB.

Objects can be "imported" without having them take up space
in the database. Their creation and maintanence can be handled
outside the Zope system.

They are rendered by "cat"ing their contents.

By permitting substitutions in the link, we can create effective
reformatting of the visible FS.

As an example, I am monitoring customer traffic. "mrtg" automatically
generates graphs for each customer.

In Zope, I could create customized displays by importing these files.

By using the ExFS, I can update the graphics without affecting Zope.

Further, assuming
 /mygraphs/today/customer1.gif
 /mygraphs/today/customer2.gif
 /mygraphs/yesterday/customer1.gif
 /mygraphs/yesterday/customer2.gif 

we can map them onto

somewhere/KustomerA/graphs/today
somewhere/KustomerA/graphs/yesterday


by substituting a property of the Kustomer

Thoughts and/or suggestions?

Time to move this to zope-dev?

anyway, I think this sounds like a good idea. It harkens back to an 
inquiry I made about byte-serving PDF files. I don't want to dump my 
pdf's into the database.

If you can implement this, I think I could implement byte-serving.

Although byte-serve could be handled at the ZServer level, I think for 
large external files it'd be more effective at the "cat" level

This is a good idea. I can see this FAQ growing very, very quickly.
So, I would suggest that we start thinking about a hierarchy
already... a couple suggestions below:

| 
| My list would include:
| 

Installation
* building
  * win32
  * freeBSD
  * etc.
* server configuration
  * zap
  * apache
  * ZServer

| DTML
| external methods
| Win32 (maybe there are specific issues, if so I don't want to read about
| them :)

I'm not sure if there will be many platform specific issues after
installation...

| SQL methods
| patches/hacks to Zope
| 
| I am sure that I can find lots of work for you!

How safe would it be, to allow any random user to use the add menu to create
arbitrary symlinks into the native file system tree?

Rather than using rowspan, use nested tables. I haven't done this in
Zope yet, but it was always my solution of choice in ColdFusion. It also
makes it easier to debug your layout in a WYSIWYG editor. It does, of
course, bloat your HTML a bit.

It will work, and I'm going to have to in the short term, but I really would
like the multiple columns for each item to line up down the page, without ugly
fixed-width hacks.

Maybe by splitting up the FAQs we could split up the work, too! Have a
different person/group resposible for each FAQ.

Of course there would be nothing stopping some energetic type being
involved with all of them :)

Also, I think that HOWTOs of the Linux type would be a great idea. They
have a person/group responsible for each HOWTO to keep it up to date and
add/edit things as needed.

I am just commenting from the sidelines. Right now I barely have time to
scan through the zope-list!

Well, I think it'd be nice if there was someone "responsible" for each
major section, this would keep everyone from getting swamped.

You can find a "howto" LaTeX stylesheet in the Python CVS checkout, and
I'm sure Guido/Fred wouldn't mind us using this.  It works real well,
and can target HTML, ASCII (I think), Postscript, PDF, etc... this lets
you do the "bigger" stuff in a nice pretty way. 

What would also be nice is a list of "bigger" issues that people would
liek to see explained more... something that's more than a single
question.

Ok, I found:

the link on that page:
you can grab [Fred Drake's documentation 
distribution], and use...
Is broken with a "Error 404: File Not Found"
Searching for "LaTeX CVS" didn't quite get it
can you please provide the links?

Subject: [Zope] etcUserFolder Product
Message-ID: <613145F79272D211914B0020AFF6401907BACC@GANDALF>

Greetings,

(This is crossposted because it is a product anouncement, and contains
interesting developer pointers)

I've have massaged the source code for UserDb and created a new user
folder products called etcUserFolder.  This products authenticates off
of a flat file of usernames:cryptedpasswords.  If there is anything
trailing the crypted password it is ignored, so any /etc/passwd file
will work.  It is generaly not recommended, however, to use your
/etc/passwd file for security reasons.

This is an unsuported product and has been written because it was asked
for a few times, and I felt the community could use another good example
of writing user folders.  It also shows off cookie authentication which
Brian perfected with UserDb.  Here is the documentation:

etcUserFolder requires a directory called 'etcUsers' in which to place
your file containing the uid:pwd pairs.  This directory may be an
INSTANCE_HOME (typicaly your top level Zope dir), SOFTWARE_HOME
(typicaly 'lib/python') or in the etcUserFolder directory.  Jim wrote a
nifty function called getPath that sniffs all of these places for a
directory and file of your choosing.  This function is included in
etcUserFolder and will be included as a standard function of the next
release.  Other Product authors may find it interesting.

Since the flat file is meant to be b/w compatable with /etc/passwd and
htpasswd style files, there is no Role associated with the users it
authenticates.  You can specify a default role which is, by default,
'etcUser'.

I have not done extensive testing of this, therefore it is a
pre-release.  Please send bug-reports and hopefully a patch to me

I just upgraded to 1.10.2 and I noticed that when creating a new document I
have a choice of DTML document and DTML method. This seems useful. I
noticed that all my DTML documents and DTML methods have the icon for a
DTML method. Everything seems to work.

What is the difference between a DTML document and a DTML method? Seems to
me a method should not be surfable but they are.

Is it possible to change my documents to DTML documents? Even just for
housekeeping.

One other unrelated question: What is a Principia Draft?

I just had a quick exchange with Fred Drake (who handles most of the
documentation duties for the Python organization), and he is aware of
this problem, and has forwarded the issue to AMK who is responsible for
teh HOWTO stuff.  IN the mean time, he suggests grabbing the latex
documentation whihc will have it all in it.  If this is too painful, I
can post a snapshot of the pieces taht are needed from the current CVS
repository.

The URL for the LaTeX documentation is:

I would love to see this feature (generating DocBook SGML). I thought

Subject: [Zope] ZMySQLDA
Message-ID: <36DDA463.683D9460@avalongroup.net>

Hi,

I'm playing with Zope, and have been trying to get Zope to talk to MySQL
using the MySQLDA.

I'm running RedHat 5.2

Since there were caveats about having MySQL development enabled, and
such, I downloaded the source distribution for MySQL and made it. It
appears to be working very nicely.

When I follow the procedures outlined in the README, the following
happens:

I run make -f Makefile.pre.in boot and everything works correctly.

I then run make and get the following error.
gcc -fPIC -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5
-DHAVE_CONFIG
_H  -I/usr/local/mysql/include -I/usr/include/mysql -c ./MySQLmodule.c
./MySQLmodule.c: In function `pythonify_row':
./MySQLmodule.c:238: warning: assignment from incompatible pointer type

-lmysqlclien
t -lm -o MySQLmodule.so
ld: cannot open -lmysqlclient: No such file or directory
make: *** [MySQLmodule.so] Error 1

I did a locate on mysqlclient, and coudln't find the file. though I did
find some called libmysqlclient. So I changed the both Setup and
Setup.in to reflect that other name. however, I still get the above
error.

Any help would be greatly appreciated.

Your problem wasn't with the library, -lmysqlclient refers to
libmysqlclient (think of the -l as short for lib). The problem probably
was that libmysqlclient wasn't on the path gcc searched for libraries.
This is controled by the -L argument (-L is library paths). 

So... here's what to do:

1. Get everything cleaned up (ie. back in the condition after first
   untarring ZMySQL).
2. Edit Setup.in, add -L<the path to libmysqlclient> to the end of the
   last line.
3. Proceed as usual (make -f Makefile.pre.in boot; make)

If this would work (having Apache parse the PHP code in the pages returned by Zope), you would save me a lot of painfull converting working PHP code (mainly database related) and I would gradually convert from PHP/Apache to Zope/Python/Apache.

Pleaz tell me how this neat trick is done... (maybe some fiddling with the headers???)

Hint:
Creating a DTML Document/method with the following contents doesn't fool Apache in rendering PHP!

<!--#var standard_html_header-->
<h2>Give me the (PHP) money...</h2>

This is my take on the situation.  As far as I can tell this is pretty
deep voodoo.

A DTML Method is what used to be just a Document in pre 1.10 releases.
DTML Methods are not objects, they are methods.  If you have a folder
called foo, and it contained a DTML Method called bar, then bar is a
method of foo.  foo doesn't contain the object bar, it has the method
bar bound to it.  What this means is that from bar's point of view,
'self' is a Folder object, and any properties it sees are properties of
foo, not itself.

DTML Documents are Zope Objects.  Their idea of 'self' is themselves.
They are contained in folders, but are not methods bound to that folder,
they are instances of DTMLDocument.DTMLDocument.  They can manage their
own Properties (because they inherit PropertyManager.PropertyManager).

Both DTML Documents and DTML Methods can hold DTML and content.  The
difference is subtle.  DTML Methods would be used when the answer to the
question 'Am I showing some other objects content through me?' is Yes.
DTML Documents should be used when the answer to the question 'Am I the
content I want to display?' is Yes.  DTML Methods have the advantage
that they don't have any properties, and their perspective of aquisition
is from their containing folders point of view.  DTML Documents have
properties which may interfere with aquisition you'd want to do, and
aquisition is from their own point of view, which may not be what you
want.

(BTW Martijn, perhaps the above should go in the FAQs)

If this isn't clear to you don't worry, it isn't even really clear to
me.  There is no way, but there really should be a way to convert
between the two because the roles for a DTML widget may change from
Method to Document as your system evolves.  This will probably be a
feature in the next release.

(This is the answer to the question 'Can I convert between DTML Meths
and DTML Docs?' for the FAQs)

You almost made it ;=)
The -lmysqlclient does refer to the libmysqlclient you found, but you should only modify the path pointing to it. This is done in the Setp[.in] just before the -lmysqlclient; modify the '-L/<path-to-the-libmysqlclient>', if have this set to -L/usr/local/lib/mysql.

[ZDP] Maybe this is something for the FAQ?

This can't be done currently. I researched this a while back, trying to
get server side includes to work. There's actually an entry in the Apache
FAQ about it:

"""
9.How can I have my script output parsed? 

     So you want to include SSI directives in the output from your CGI
     script, but can't figure out how to do it? The short answer is "you
     can't." This is potentially a security liability and, more
     importantly, it can not be cleanly implemented under the current
     server API. The best workaround is for your script itself to do what
     the SSIs would be doing. After all, it's generating the rest of the
     content. 

     This is a feature The Apache Group hopes to add in the next major
     release after 1.3. 
"""

Though this is about SSI, it basically means (I believe) that apache can't
take back the output of a CGI for additional module handling.

Hi  Sture,
try to use the P MySQL Input wizard in the contrib download area. It
will automatically create a insert sql method and a form for you. So you
can just follow the pattern.

I'm piggy backing this on Amos's post from a while ago, because that is
where I finally found my answer. I could have sworn I had seen (and
used!) a DTML code fragment that displayed the form variables sent to
it, with there values. Obviously, this involves indirection. 

After hunting through my (extensive) zope-list archive, I couldn't find
it, so I started over, with the help of Amos's text and wrote one. I
often need little tools like this to debug between my forms and sql
actions, so I can see what's really going on!

I call it 'show_vars'

The only tricky thing in it is that sequence-item is an invalid variable
name, so I need to wrap it in _[''] which leads to the double wrap when
dereferencing to get the value. Anyway, hope someone else finds it
useful!

I haven't tried it, but it could possibly be done by running two
Apaches: one which stands "in front of" the other.  The front-side
Apache would rewrite every access into a PHP wrapper-script which
include()s a corresponding URL from the back-side Apache where the
Zope things would be done.


On the other hand, I really should be asleep now so all this _may_
be utter nonsense, but I do think it's possible.  It may even be
possible with a single Apache, but that's more hairy than I dare think
about right now.  Good night.

(Btw, my suggested hack isn't in total disagreement with the quoted 
FAQ entry, because my hack surely won't work with SSI.  PHP3 isn't an
official Apache module, so they don't neccessarily mention things like
this in their FAQ.)

In all the world you might find 4 machines still plugged in that
support 'record' or 'page' structure.  The default is 'file', which is
what that command is trying to do.

Add these two methods to ftp_server.py::ftp_channel

    def cmd_stru (self, line):
        'obsolete - set file transfer structure'
        if line[1] in 'fF':
            # f == 'file'
            self.respond ('200 STRU F Ok')
        else:
            self.respond ('504 Unimplemented STRU type')

    def cmd_mode (self, line):
        'obsolete - set file transfer mode'
        if line[1] in 'sS':
            # f == 'file'
            self.respond ('200 MODE S Ok')
        else:
            self.respond ('502 Unimplemented MODE type')


And that should do the trick.

Micheal answered these perfectly.

>One other unrelated question: What is a Principia Draft?

It is a special use of the session object, but it appears to be partially
broken. When you create a Principia Draft, it asks you to specify an
orginal object, from the same Folder you are creating the Draft in. This
will be your 'draft', on which you can make changes invisible to the
outside world.

The draft contains an invisible Session object that is immediatly started
and joined, and an invisible UserFolder to facilitate extra users (for
example, customers that want to be able to view your work on it as well,
but have no access to it otherwise).

The Principia Draft suffers two problems however. The first is really a
Session object bug, in that security for Session objects is broken. This
has allready been reported as a bug to the Collector by me. The second
problem is that the Userfolder and Session controls are inaccessible via
the management screens.

The latter problem is caused by convention changes in the Folder object (or
the ObjectManager class really, used by Folder. I think that Folder objects
_used_ to call title_and_id on a object when displaying it in it's
management screen, but the current release of Zope constructs the id and
title of an object by using it's id and title separetly. Principia Drafts
made use of the call to title_and_id to insert links to its UserFolder and
Session controls. As this now doesn't happen anymore, you will have to do
this yourself.

As long as you have access to Session objects, you can change users on a
Principia Draft object by calling it's users__draft__.manage_main method,
and reach the Session controls by calling its manage_approve__draft__
method. The URLS are:
http://yoursever.com/Zope/Draft/users__draft__/manage_main and
http://yoursever.com/Zope/Draft/manage_approve__draft__

   As far as I understand there are DTML objects (templates), Products and
External methods. There is no such thing as "Internal" methods (objects,
that live in Zope's object database). Are these 3 the only 3 kinds of
executable (callable) things?

    By using the #in tag, you can easily all show all data in any dictionary
    object, like REQUEST.form, REQUEST.cookies and even REQUEST itself. Just
    call the items() method of the dictionary, and the #in tag will provide
    a sequence-key and sequence-item variable for every item in the
    dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>
        <!--#/in-->

    Use REQUEST.cookies.items() for all your cookies, and REQUEST.items()
    for all REQUEST variables, including CGI Environment variables.

I'm randomly assuming here you know more about DocBook SGML than I do,
so here I'm involuntarily inofficially  but you can back out of it
immediately appointing you the ZDP DocBook SGML expert. :)

I think perhaps the first thing you could do is get together with people
in the Latex thread for docs; they seem to have come up with it
independently. I know even less Latex than SGML and SGML seems a closer
fit with the XML-ish direction the web's taking, so my question would be
to point out the advantages of SGML to everybody.

Yup, splitting up the FAQ into different categories appears to be pretty
needed, so this is a good idea. My idea is to 'involunteer' you category
maker guys to take the assembled FAQ that I'll produce hopefully today
(in a few hours), and put each question in the category you feel it
belongs to. This way I have to do less work and thinking. :)

Subject: [Zope] Bobo or ZPublisher and stdout ( Solution: Client/Server)
Message-ID: <36DE5733.60F87988@oi42.kwu.siemens.de>

Hi,

I already sent some postings to this topic, but I would like
to discuss the following problem again and how it could be solved.

Imagine there is a big C++/Python project.
The application is mainly prgrammed in C/C++ und one supports
a scritpting interface to that application via the SWIG mechanism -
the target language is Python.

During the developping process many stuff is written to the stdout -
during initialization ( before the main-function ), during execution (
in the main-function ),
and in the destructors of the static instances ( after the main-function
).

Now we want to do some web-stuff via ZPublisher, we define
a function which return a html string, which is calculated through
calling functions
from our scritpting interface of our application, that means beside my
correct
calculated string there is many stuff sent to stdout, that confuses
the Xserver and I get an error.

Ok, you would say switch the stdout to a file via calling c-funcions
like dup() or dup2( ) and
encapsulate this in a function (wrapped via SWIG), which is called in
the function which I call from
the URL in the browser.

Less cryptic:

 xy.py:

   start():
       "XXXXXXX"

        #Now all stdout goes in a file
       stdout2file( "log.txt")

        ....
       HTMLstring = ....

        # sitches the stdout back ( REVerse )
        # The way is free for CGI
        REVstdout2file()

        return HTMLstring


the URL:    http://myserver:3333/yyy/cgi-bin/xy/start

BUT with this method I have no chance to chatch stuff which is written
to the stdout
in the destrutors of the static instances, because we already have
switched back to the
"usual" stdout (for a correctly working cgi-mechnism).
The some problem one have with things which are written
to the stdout during the initialisation of the static instances.
( Imagine python itself is compiled
against a library which writes some stuff to stdout during
initialization).

I see only one solution:
If there is a ZPublisher Server process which says to a client process
do everything
and give me a calculated string via sockets or something like that, I
have not to take
care about stuff which is written to the stdout at the client process.

Or are there better solutions ?

   Thanks in advance,

    Armin

Yes, this would be a good idea. My first priority however is to get as
much of a FAQ as possible out there. Organization we'll do at the same
time. Otherwise we run the risk getting bogged down in organizing who
does what. 

That said, volunteers who want to manage specific sections of the FAQ
are very welcome to step forward. Procedure is as follows: you get to
name your topic; the first person who names a particular topic and
produces a FAQ for it (assembling it from the FAQ we have now, and
hopefully adding more of his or her own to it) will be manager for that
section, unless that person doesn't want to, of course. :)

I suggest to mail this list instead of me personally, so that other
people can respond friday and during the weekend, when I won't be around
to check the mail. We're working on getting a zdp@zope.org mailing list
too, but I can't say yet when that'll be ready.

Aren't there some HOWTOs out there already on the Zope site? (there are
FAQs too but that doesn't stop us of course). HOWTOs and FAQs of course
have some overlap; we'll just see how it evolves.

Earlier I suggested using SGML Docbook for this purpose; I've appointed
John Eikenberry (without any feedback from him :) as our official SGML
docbook expert. One advantage of Docbook SGML is that it's the new Linux
standard for writing documentation.

I think essentially a HOWTO is a particular frequently asked question
with a very long answer. :)

My rough sketch right now is a four-day course:

Day One -- Zope for Content Managers
Day Two -- Zope Programming Using Zope
Day Three -- Zope Programming Using Python
Day Four -- Relational Databases and Zope
         -- Zope for System Administrators

It would be a professionally produced and delivered "in the classroom"
class, a la Learning Tree.

That is, I won't be doing it. :^)  Instead, I'll produce a poor version
of the whole thing and give it to them, including the first customer
that will send maybe 7 people.  My poor version would probably become an
online version.

Just my thoughts currently.

I guess this counts as an announcement. Ken asked me to do it, but I
just mailed him I'd rather he did it (as he knows more about these

    then. If you try to feed this FAQ through::
     
        <!--#var faq.stx fmt="structured-text"-->

    there will be an error message in Zope, however. For some reason
    Zope seems to try to interprete even StructuredText that uses &amp
    escape codes. Until this issue is resolved it is not possible to
    render this document into HTML.

    In my uninformed opinion, StructuredText code examples shouldn't
    be interpreted by Zope as actual DTML. There may be some rather
    subtle technical difficulties involved however. Any input on this
    is very welcome. Until the matter is resolved, the FAQ document
    will use StructuredText in the plaintext readable way.

    Thanks to Martijn Pieters in being so considerate to supply HTML
    escaped DTML examples; it's unfortunate his efforts weren't useful
    this time.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like REQUEST.form, REQUEST.cookies and even
    REQUEST itself. Just call the items() method of the dictionary,
    and the #in tag will provide a sequence-key and sequence-item
    variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>
        <!--#/in-->

    Use REQUEST.cookies.items() for all your cookies, and
    REQUEST.items() for all REQUEST variables, including CGI
    Environment variables.

* What is a Principia Draft?

    It is a special use of the session object, but it appears to be
    partially broken. When you create a Principia Draft, it asks you
    to specify an orginal object, from the same Folder you are
    creating the Draft in. This will be your 'draft', on which you can
    make changes invisible to the outside world.

    The draft contains an invisible Session object that is immediatly
    started and joined, and an invisible UserFolder to facilitate
    extra users (for example, customers that want to be able to view
    your work on it as well, but have no access to it otherwise).

    The Principia Draft suffers two problems however. The first is
    really a Session object bug, in that security for Session objects
    is broken. The second problem is that the Userfolder and Session
    controls are inaccessible via the management screens.

    The latter problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately. Principia Drafts made use of
    the call to 'title_and_id' to insert links to its UserFolder and
    Session controls. As this now doesn't happen anymore, you will
    have to do this yourself.

    As long as you have access to Session objects, you can change
    users on a Principia Draft object by calling it's
    'users__draft__.manage_main' method, and reach the Session controls
    by calling its 'manage_approve__draft__' method. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main 

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

Hm, DTML methods can be called as well, naturally, that's why they're
called methods. They're called through URL. The DTML method then is
executed. This means executing any DTML in it and returning the
resulting HTML to the caller. One way of 'calling' a DTML method is by
using it in a form action, like this:

    <form action="your_dtml_method" method="POST"> 

(or method="GET", of course)

This does go through the browser, but it feels like you're calling
'your_dtml_method' when the user presses the submit button.

This is another way of 'calling' a DTML method:

<!--#var your_dtml_method-->

I'm sure there are more ways, and I'm a bit vague about this, so I'll
leave it up to other people to turn this into a nice FAQ. :)

Martijn

So that is what the MySQL Input wizard does. I've been meaning to look at
it. Instead of saving time by using it, I did it manually. It is not that
hard but you have to understand what is happening.

1. HTML form (eg. form_html) collects data and sends it to a DTML document
(eg input_html) (that is the only tricky concept).

For example:

<form action="input_html" method="get">
  <input name="num:int">
</form>

(That :int tag does error checking. It is optional. They are documented in
the Z SQL Database Methods User's Guide)

2. The receiving doc (input_html) calls an SQL method (eg input_sql) with
an in tag.

<!--#in input_sql-->
<!--/in-->

If you do a select after your INSERT or UPDATE you can use it between the
in tags, otherwise you can just display a message or do a redirect after it.

3. Your SQL method (input_sql) would be something like:

INSERT INTO database (num)
VALUES (
   <!--#sqlvar num type=int-->
)

<!--#var sql_delimiter-->

SELECT num, etc

You don't need to do a select but if you do don't forget the <!--#var
sql_delimiter--> between any SQL statements.

Have fun!

If you don't do anything with the returned data, a #call will suffice:

<!--#call input_sql-->

Hi.  I've been getting a lot of confusing complaints about gadfly
that turn out to be Zope bugs.  Just for the record.

ZGadflyDA doesn't support more than one db, gadfly does.
ZGadflyDA doesn't support newlines in string literals, gadfly does.
ZGadflyDA doesn't include kjbucketsmodule which makes gadfly run 10x
faster.
ZGadflyDA packages gadfly beta 0.2, whereas the current release is 1.0

I'm sure these will be fixed soon, in fact I'd offer a patch if I could

As a new zope user, and also according to my general documentation
sensibilities, 
i suspect it would be very valuable to have a catalogue of the various
special variables (like sequence-key and sequence-item) and the various
entities (REQUEST.cookies, ...) available to the DTML programmer.  There
may already be some sort of catalogues around - in which case pointers
to those kinds of resources would be very nice to have...

I think at least this part of your problem may be due to the fact that Zope
is running as a different user under IIS than it is under ZopeHTTPServer.
My guess is that it can't see your datasources since they weren't created
as 'System' datasources. Check under the windows ODBC control panel and
make sure your DSNs appear under 'system dsn', not 'user dsn'.

The most supremely easy way is::

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the
MySQL
module to make sure it works. When I do, I get yet another error.

Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: libmysqlclient.so.6: cannot open shared object file: No
such
file or directory

The file does exist, so I am once again stumped.

Thank you for your continued assitance.

If it had been reported to the gadfly-rdbms list

post script:

The current usage of gadfly in Zope makes gadfly do lots of parsing as in

insert into table(a,b,c) values (1,2,3)
insert into table(a,b,c) values (6,2,3)
insert into table(a,b,c) values (1,7,3)
insert into table(a,b,c) values (1,2,8)

The "right" way to do this would be to take advantage of gadfly's
dynamic parameter/multiinsert feature executing

insert into table(a,b,c) values (?,?,?)

ONCE with dynamic parameters list

[(1,2,3), (6,2,3), (1,7,3), (1,2,8)]

which would run much faster than thrashing the parser
with the individual inserts above (with kjbuckets present).
In general dynamic parameters on repeated statements reduce
parsing and binding overhead (even for other types of statements).

However, I understand this may be hard to implement as
it would require special features for the gadfly "adapter"
not of value for the other adapters. Oh well.

Anyway, in future please post/forward/crosspost any gadfly
related issues to the gadfly list.  I just discovered a pile of
complaints on the zope list this morning and I found it
distressing.  I don't normally read the zope list.

How can I evaluate a #var equivallent for setting a tag attribute value?

For example, Zope doesn't like this:

    <!--#sendmail smtphost=<!--#var smtpHost--> -->

or this:

    <!--#sendmail smtphost=smtpHost-->

(it tries to use smtpHost as the host name, instead of its value)


Help!

Try:

or this:

<!--#sendmail "smtphost=_['smtpHost']"-->

Subject: [Zope] Using Zope with CORBA (new user question)
Message-ID: <199903042212.RAA16927@hog>

I have a long running process that will be started by Zope.  This
process has a CORBA interface that is implemented using ILU.  I would
like to be able to asynchronously have this process generate data for
Zope.

My basic questions are:
	o Can I have an ILU mainloop inside of Zope?  (I really don't
	  care if I have to hack Zope or if I can use an external
	  method.)

	o Should I fork/exec the long running process and give the
	  process a URL that indicates where the data should be
	  written?  (I can use pickles or sql.)

	o How do I tell Zope that new data is avaliable if the process 
	  is external to Zope?

Message-ID: <Pine.LNX.3.96.990304141142.8459C-100000@taos.kavi.com>

Ok, what's the trick to getting special characters to be converted to
their escape codes (eg. " to &quot;). This is particularly important for
forms in which the user may enter these types of character. 

For instance, if I create a property on a folder that is a string, and if
the string I enter has quotes around it... it doesn't show in the
interface the next time I go to edit the properties. For example, in
MCExam, the 2nd sample question has this as an answer "bar, spam". If I go
to the folder's properties to change it, it doesn't show up. In the source
it looks like: 

<input type="text" name="ans3:string" size="35"
   value=""bar, spam"">

Obviously, if I then save changes, the value is gone altogether.

Is there a way of automatically converting quotes and other special
characters to their escape codes (like the sqlquote method)?

Thanks,

I do not know much about CORBA but you might find it helpful to check the
ZClient library that comes with Zope. You can use ZClient to script Zope
actions. In other words you can have your CORBA proccess running
independently of Zope and whenever there are available data you can call
Zope using ZClient and update whatever you need to.

Grovelling through the source I find something called html_quote in 
lib/python/DocumentTemplate/DT_Util.py, so I tried:

<!--#var nastyvar html_quote-->

Which seems to so the right thing in the generated source. I'm not sure
how to get at the equivalent method call, though.

Does that help?

(p.s. there's url_quote, as well)

I think we're trying to assign a string where a mailhost object is needed.
I'm not sure how to get around this, without an external method. Though
with an external method, it'd be pretty simple:

(warning: untested)

def get_mailhost(self,property_name):
	""" gets the mailhost """

	mailhost_id = getattr(self,property_name)
	return getattr(self,mailhost_id)
	
Or something like this... [shrug]

Both answers are much appreciated. Things start to clear up, but ...
As far as I understand zope it should also be possible to have forms send
data directly to external methods. How do I go abouth to make the argument
list in a python function so that it receives more than one 'form variable'.
1 is simple, but my form consists of 5. I get an error constructing the
python function to take 5 arguments. How is the 5 'variables' sent to the 
method? How do I get hold of the values each store?

Lotsa questions - probly me doing things the wrong way but - I'm learning:)

Yes. This is just what I was looking for.

This leads to a followup question/request for the group.

'manage_addProperty' calls various converters from ZPublisher.Converters
to format the properties values. Shouldn't html_quote be used when
formatting strings and text? This would be trivial to change. Would this
cause some problem I don't realize? If not, I'd like to add this to the
Collector for the next version.

zope.org.

The header inserts a <!--#var sidebar--> in the left column.  The
sidebar DTML method is:

<!--#in expr="objectValues(['Folder'])"-->
<!--#if hidden -->
<!--#else -->
<a href="<!--#var id-->"><!--#var title--></a><p>
<!--#/if -->
<!--#/in -->

(show links to sub-folders which don't have the 'hidden' property set).

The above works fine in the toplevel folder.  In the subfolder, however,
nothing shows up, even though there are two folders which do qualify.

I'd tried originally to have it be a DTML Document and change the expr to
_.objectValues(['Folder']), but that doesn't work at all.

What am I missing?

Check if your DTML properly closes all tags. I had something similar
happening to me in a complicated DTML, when some condition failed to add a
</TABLE> tag. 

BTW you can use
<!--# unless hidden-->
...
<!--# /unless-->

Yes! This was exactly what was causing the error. I added a new 'System
DSN' which then showed up under IIS, and now I've got a shiny new and
perfectly functional Z ODBC Database Connection. 

Much thanks!

- Jay

PS - Don't know if this info is helpful, but I noticed that (after I set up
a valid System DSN) when my attempt to add a new Z ODBC DB Connection in my
IIS/1.10.2 environ was flawed for whatever reason I would receive the
cryptic 'HTTP Error 400 - Bad Request' from IIS. After some very quick
poking around I noticed that even after selecting a valid dsn, flaws such
as trying to add a connection with an ID already in use, or entering an
invalid connection string would give this 400 error - whereas in my
ZopeHTTPServer/1.9 environ I would receive relevant and helpful error
messages in such situations... Wish I knew more about how to help fix...

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the
MySQL
module to make sure it works. When I do, I get yet another error.

Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: libmysqlclient.so.6: cannot open shared object file: No
such
file or directory

The file does exist, so I am once again stumped.

Thank you for your continued assitance.

Where exactly is the file?

find out by doing a locate 'libmysqlclient'.

Let's assume that it is in /usr/local/mysql/lib.

The easiest way to accomplish what you want is this.

1.    cd /etc
2.    vi ld.so.conf
3.    Goto the end of the file and add a line that says
'/usr/local/mysql/lib'
      replace this with the exact location of you libmysqlient.so.6
4.    save the file
5.    run 'ldconfig'
6.    run 'sync' twice, this just makes sure all changes are written to the
disk.

This adds the mysql lib directory to the lib search path.

Why not use a MailHost Object? On that object you can then set the
appropriate SMTP Host, even from DTML code..

Yes, because you sometimes (most of the time, really), want to have the raw
input from the user. If you then use this raw input in HTML again, only
*then* should you quote out any HTML. Besides, what if I want the data to
be URL quoted? Or SQL quoted?

Just a quick shot: Could it be that the value 'hidden' is aquired from
somewhere else?

I did notice today that IIS 4.0 seems to be the cullprit. Whenever Zope
returns a 400 error (like 'sorry, an error occured') IIS mangles that into
the 400 Bad Request error.
This means the traceback is also gone. *grmbl*. Just try and add a
Principia Draft and not specify an ID, and compare this to the message
returned when using ZopeHTTPServer. I think I'll switch to ZServer.

Maybe this should go into the FAQ... I'll cc to ZDP

BTW, I hereby retract the bug I reported to the Zope Collector regarding
ZODBC connections being broken. I forgot to fill in the ID :|. IIS mangles
the returned errormessage.

What is the procedure for retracting bug reports? mail support@digicool.com?

Message-ID: <Pine.LNX.4.04.9903050506001.1539-100000@gaaros.msrc.sunysb.edu>

Zopistas

I have encountered problems mainly associated with ZServer and ZAP:

I am using Zope-1.9.0 and the preconfigured Apache server to run my Zope
site. Last night (a couple of hours ago!) I installed ZServer. It wouldn't
run and I had to add the following to start.py to fix it:

import sys,os
sys.path.insert(0,os.path.join('..','lib','python'))

Later on upon entering the management screens I noticed that the id of the
top level folder dissappeared which caused the paths to my objects to
change. With ZAP (the preconfigured apache) I would visit:
http://www.gaaros.com:8080/Gaaros/ to get to the top level directory but
with ZServer is: http://www.gaaros.com:8080/ which spoils all kind of
links that people have on my site.

Switching back to ZAP I got the following error:

  <FONT SIZE="+2">Temporarily Unavailable</FONT>
  <P>
  The resource you requested is temporarily unavailable - please try again
later.
  </TD>
</TR>
</TABLE>
(102) failure during connect
<!--
No such file or directory
pcgi-wrapper-version 2.0a5
-->
</BODY></HTML>  

Seems like ZServer changed my root id from "Gaaros" to nothing.
I called PickleDictionary on Data.bbb directly from python but I could not
even see the subobjects. BTW can the Zope Data.bbb be accessed directly
from PickleDictionary??

Also trying to shut ZServer from the control-panel results in a core dump.

Ok enough for now, its very late and I cannot think anymore.

If anybody has any clues about the root object id problem please let me
know.

Thanks

Pavlos

No problem. Basically I filter all emails arriving in my personal account
that contain FAQ in the Subject: field. As I am subscribed to all the Zope

This is a poor answer (as most here know I don't have the mental
horsepower to provide good responses :^), but...our _intention_ over
time is to have "ZServer" allow objects to be published via PCGI,
FastCGI, HTTP, FTP, and CORBA simultaneously.

Ideally we'd get some kind of Python implementation into the Medusa
handler layer.  Obviously this approach has some serious drawbacks...

Anyway, I realize that I'm not providing much of an answer, so sorry :^(

Right, understood.  We had to spend a lot of time figuring out Gadfly in
order to host it inside Zope.  Thus we labeled it "Demo".

I imagine that it is best for everybody if we take Gadfly out of the
base Zope and make it an external, no-warranty package like the MySQL
support.

I appreciate your patience and taking the time to submit well-thought
questions.

This is really weird, it just reminded me of a (rather pathetic) dream I
had last night.  I dreamt that someone created a Python module that
would read Word files.

My DreamTV must be picking up the wrong channel.

I've been awfully interested in XML in the last few days.  Can you
describe what user-visible benefits PHP delivers due to its integrated
XML parser?

Additionally, we are working on Zope searching for a consulting project
right now.  Actually it is Zope Cataloging.  It's still a
consulting-only option, but plans are that eventually it will go "below
the line".

Ahhh, you too, eh?  Did you have the dream about the chimp and the

I *think* I have some good news to report on this, but before I squawk,
could you detail this gut-wrench a bit more?

There have been a lot of suggestions on this one.  Here's another one: a
command-line program that takes everything out, such as the wget
program.

I'd like to have this as well.  I've been doing a lot of thinking about
this lately.  It is a bit more complicated than expected, though...

This is the main reason I replied.

Having Zope as a free and Open Source(tm) platform is the heart of our
business plan.  A closed Zope would basically mean we start over
completely as a different company.  Thus, closing Zope is roughly
equivalent to closing our company.

With _that_ said, we still need to provide some assurances that we won't
legislate the connection between Zope and DC.  First, we are trying to
keep some arm's length distance between zope.org and Digital Creations.
We hope to formalize the way the community participates in the platform.
We expect to make it lucrative for other businesses to participate.

At the same time, we intend to pursue commercial opportunities atop the
platform for vertical applications.

Ultimately this is the same question put to Netscape regarding Mozilla
during the AOL talks.  The answer is simple: "The genie is out of the
bottle."

Since it is open sourced, Digital Creations must *earn* its stewardship
of Zope.  If we don't we'll become less relevant.

Earning the community's enthusiasm is pretty simple, I think.
Unfortunately we aren't doing a good job right now, though we are trying
damn hard.  But we'll keep trying...

In the meantime, I'm absolutely ecstatic to see folks in the community
step forward over the last month and lead the way.

Yep, the zope.org machine has five virtual hosts.

Previously answered.

Ditto.

We put them in the database.  The 3 Mb Zope binaries are served out of
the database, the PDF files are served out of the database.  This works
so well I don't even think about it any more.

hmmm. That's interesting because it works just like oracle or it
should,unless there are more bugs you haven't passed on to me.  Let me know
what caused the problems.  Basically any non-conformance with the db-api
is a bug.  Please report it to the gadfly-rdbms list.

Yes, this is fine.  BTW, it might be hard for your existing customers to
upgrade to Gadfly 1.0 since I think the db file formats are different
(that's why it was called beta, so I could change things like that).

I remain, Yours Truly,  Aaron Watters

I would suggest, first off, to use 1.10.2.  ZServer is being developed
against 1.10.2, and the latest Zap was tested and confirmed to work with
it.

Yes, there were discussions on this in the list about this problem.
Someone needs to go back, rassle up the discussion and submit it to the
ZDP.  Looks like you found the fix.

Hm.  Is your Zap .pcgi file named Garros or does your RewriteRule look
for Garros and then call PCGI?  If so that is why you need to use Garros
to reach the server.  ZServer can server right out of Zope and doesn't
have this problem.  Your description makes this sould like it is a
production site, I would not suggest running ZServer on a production
machine as it is alpha and still buggy.

This error comes from PCGI.  It can't find your .cgi file so Zope isn't
even being launched.  Did your zap.conf file change (specificly the
RewriteRule)?

You can open a Data.bbb file into a PickleDictionary, but you won't see
anything useful unless you really know what your doing.  The Database
itself is not a Pickle, it is a database of Pickles.  I have attached a
small 5K script that will be released with 1.10.3 which paruses the
database and generates reports.  In the future we are intending it to
translate the entire database into XML for transport. (Note, we do not
intend to use XML as the db format)

I suspect this is because you are using 1.9.0

It's allways worth while! :)  I think the point paul was trying to push
is that we are interesting in publishing our objects over various
transport protocols.  If you want to look in this direction, probably
the best idea would be to write a Medusa handler.  Check out Sam's site
at:

http://www.nightmare.com/medusa

There currently exists an ftp and http medusa handler for Zope, which
you can look at in the latest ZServer alpha release availabe at
zope.org.  I'm not sure is there is a Medusa CORBA handler or not, I
suspect not, but maybe there's some type of CORBA out there written in
Python?

Yes.  ZServer really restores Zope's original intent from the Bobo days:
publishing objects through a variety of protocols.  I think ILU support was
once attempted back in those days.  However, a Bobo app at that time could
only have one publishing mechanism (ie, CGI, PCGI, FastCGI, ILU, etc...).
ZServer allows for multiple publishing mechanisms in the same application,
allowing access to the objects through the web, through FTP, or through any
other protocol developed for ZServer/Medusa.

Subject: [Zope] Documents for web and paper
Message-ID: <012c01be6729$74f6bd40$0201a8c0@hawkeye.bob.oc>

I'm looking for the best way to store and
retrieve documents with these requirements:

SPECS
*Easy storage and retrieval on the web
*Pretty printing on paper
*Easy simple collaboration (no checkout)
*One BASE format for both web and paper
*Base format *could be* edited with
   Word or WP
*Preserve text markup:
   bullets, bolds, underlines,
   tables, graphics, links...etc.
*Search by keyword
*Search by full text


*******
I look forward to comments and
Ideas on implementing this in ZOPE
Perhaps some of this has been solved
already and I don't know it.

EXAMPLE:
Say you have a small book/article
 that is fully contained in a WORD
or WP file.

It has chapters and sections:

Chap1 Plants
      Section1: Trees
      Section2: Flowers
      Section3: Vegetables
      Section4: Fruits
Chap2 Animals
      Section1: Dogs
      Section2: Cats
      Section3: Fish
      Section4: Humans

Ok, as a paper document in the
word processor it is laid out *nice* with
a new page for each chapter, section,
and subheadings for groups of paragraphs in
each section. It prints *nice* and can
even have a table of contents and index.

For the web, the whole book could be
one LONNNG web page.  Ugly and it
doesn't work well.

Ideally on the web each chapter and section
would be navigable with a left hand frame
like table a la http://www.zope.org.  Then
sections can be placed on separate pages
on the right.  This means that the one source
document becomes multiple html
"files" on the web site.

*Tree Navigation
Ok, for tree navigation like
http://localhost:9673/QuickStart
Each Chapter and Section becomes a folder and
the text from each section is contained in the same
named: "dtContent"  as in
...9673/QuickStart/Outline/Applications/External/dtContent

While the tree is nice,  and separate html "files" make the
website better,

*REVISIONS with TWO OUTPUTS

How do you do:
Make revisions to the source document in word/WP
and have it FLOW automatically to html format or
tree format for the web?

*Perhaps* XML could come to the rescue as holy grail
to help solve this problem???  I understand the idea
of mark up but how does it solve the problem of two outputs?

Can you have a template that automatically chops up
the SOURCE into the appropriate folders/files etc and
feeds it to ZOPE?   Can this or another template reformat
for pretty printing including page numbers that are
updated based on the planned printing?

Maybe I need to reconsider how documents are
stored as source, i.e. not Word.  And if not,  what
tool or mechanism would be best?  Maybe the
NATIVE source could flow to Word/WP or
via a template making for pretty printing.

Maybe for simple stuff, the source could be
simple text entered on a webpage or sent
by e-mail with *simple* markup and parsed
automatically?

*KEYWORD SEARCH
Ok, on the web (and Zope), the benefit is it's
searchability:  Do we "hide" keywords in the
source somehow and in addition use Chapter
and Section titles as Keywords?

Search for: "dogs"  gives a result of
Chapter 2 Section 1 in the example as
one entry.  Additional entries might
be lessor cross references such as
a keyword "dog" in the Section 4 humans
as "man's best friend".

*FULL TEXT SEARCH
Ok so we search for the word "Daisy"
and this word is found in the text in
sections: Flowers, Dogs (as a pet name)
and Humans (as a proper name).

The result is then three line entries that
take you to the words.

*Zope IDEAS for this?

I assume that it would be best to store
the documents and source in the ZOPE
database rather than an external datasource.

Thanks for any input on this

Nah -- getting rid of the hidden test doesn't change a thing.  Sorry I
confused the issue with that.

I think my problem has to do with my lack of understanding of the
interactions between acquitision, DTML Methods, DTML docs and namespaces.  
I just noticed that the standard html headers and footers are methods.  
That means, if I understand the earlier email, that the default namespace
in them is that of the thing they are contained in.  So, in my case, the
top-level Folder.

Now, in the sub-folder, the standard html headers and footers are acquired
from the toplevel folder.  The standard header does a #var sidebar, which
also lives in the toplevel folder, and that gets included fine.  Within
that sidebar, I'm not sure what the default namespace is -- my fuzzy
understanding makes me think that it should be either:

  a) the / Folder (the 'physical' container for the DTMLMethods)

  b) the sub Folder (the container for the thing which did the
     aqcuisition, namely the index_html DTML Document.

Problem is, neither of these makes sense given what I'm seeing.  If it was
a), I'd expect the 'objectValues()' call to return the same list of the
subfolders of the toplevel folder every time.  If it was b), I'd expect
the thing to work and give me the subfolders of the subfolder.

Let me try to summarize the hierarchy:
  
   /
     - index_html  (#var standard_html_header...#var standard_html_footer)
     - standard_html_header (#var sidebar)
     - standard_html_footer
     - sidebar
     SubFolder1/
     SubFolder2/
        - index_html  (#var standard_html_header...
                       #var standard_html_footer)
        - SubSubFolder1
        - SubSubFolder2       
    
The top sidebar shows SubFolder1 and SubFolder2, the /SubFolder2 sidebar
doesn't show a thing.

PS: Thanks to pavlos for pointing out the #unless tag.

PS: For some reason the title of the root folder is "Zope" in the
    properties tag but doesn't show up in the tree or in the pathlinks.
    Anyone have a suggestion?

Try: <!--#var "sidebar(PARENTS[-1],REQUEST)"-->

This will call the method using the root folders' namespace, thereby
showing all qualifiying subfolders regardless of where the method is
called from. You might have to modify your method to construct absolute
URL's.

Thanks!  What I actually wanted was sidebar(PARENTS[0], REQUEST), but you
pointed me in the direction I needed.  Now I have to understand it, but
that's much easier with working code. 

This also led me to find a bug.  I was wondering why the REQUEST parameter
was needed, so I tried to remove it.  The next time I loaded a page
calling this code, the ZServer process died with the Win32 equivalent of a
segfault.  Is it just me?  I don't dare try it on another Zope server =).

Yeah, I already figured out that the problem was actually in the
OFS/properties.dtml file (I moved over to the zope-dev list, as I realized
this thread really belongs there). In properties.dtml the 'string' type is
listed twice:

  <!--#if "type in ('string', 'int', 'long', 'float', 'date')"-->
  <input type="text" name="<!--#var id-->:<!--#var type-->" size="35"
   value="<!--#var "_[id]"-->">
  <!--#elif "type=='string'"-->
  <input type="text" name="<!--#var id-->:string" size="35"
   value="<!--#var "_[id]" html_quote-->">

'string' needs to be removed from that first list. I'll be submitting this
to the Collector.

I'm new to Zope. I'm very excited about it's potential, but my first
impression is that I will need to master Python in order to use it. I
believe Python is an excellent language, but I do not have the time to
learn it. Several questions about this:

- Can I achieve anything useful in Zope without touching Python? I can
learn DTML, of course.

- if so, what I can and what I cannot do without Python?

- could I, for instance, do something like slashdot.org without Python?

- is there a plan to give Zope features (or ready-made
modules/factories) that would completely eliminate the need to work with
Python (for certain tasks that can be automated or turned into
templates)?

I found a great description about XML in:
"20 Questions on XML"
http://builder.com/Authoring/Xml20/index.html

On Paul's Zope roadmap: (Jan 18th)
http://www.zope.org/Information/Roadmap

"(2) XML. Zope is a great fit for XML, even better 
with the machinery from Tabula going in. We also 
see XML becoming the basis for other initiatives, 
such as WebDAV and RDF. However, we just can't 
squeeze out the time to dive in deep. Rather, we'd 
love to see more community progress like that 
which popped up this weekend."

I did a search for postings that had "XML" 
in the subject and found
55 messages in ~6 threads between
Jan 8th and Feb 2nd

Other messages have "XML" in the body.

Hopefully we can get some OUTLINE of how ZOPE
and XML can work together.  --- A framework for
further discussions.

You do not need to know a single line of Python to use Zope.  But
learning Python is a pleasure, not a chore.

You can do just about anything with DTML.  In fact, most 'Products'
(read that, 'Zope Extnesions') are mostly DTML.  If your not writing a
Product then you can stay entirely in the domain of DTML.  DTML does use
a small bit of Python in itself, these are called expressions.  For
example, if you had an integer called num you could use:

<!--#var num-->

to 'render' it in your web page.  To get num + 1 you would use:

<!--#var "num + 1"-->

The contents of "" is a python expression.  But it's not a python
program.  If we didn't use Python we'd of had to have come up with some
other language like way of doing this that you'd have had to learn
anyway.

> - if so, what I can and what I cannot do without Python?

Python is used for the following:

To write Products. This is hard core development.

To write External Methods, which are used to hook special or
wierd/pre-existing python functions into Zope.  This is rarely necesary.

Yes.  There may be a 1% slice of something like slashdot needing a bit
of Python.  But remember, slashdot is a huge application written
entirely in Perl.

Yep.  These are called Zope Classes.  They are still in-house here at
Digital Creations because we are still debugging/figuring them out.  A
Zope Class lets your create your own objects that can be added into Zope
without writing Python code.

Message-ID: <Pine.LNX.4.05.9903051612490.29905-100000@web.spyderlab.com>

More information on my front.. I've been fiddling around a bit trying to
find out what is going wrong..

I'm using ZServer/Zope 1.10.2 with ZMySQLDA that I just downloaded 2 days
ago.

The traceback is as follows:

<!-- Traceback (innermost last):

    (Object: CopySource) TypeError: (see above)
-->

line 384 of DA.py -- __call__ reads:
query=apply(self.template, (p,), argdata)

I added a bit of debugging code and was able to a take a look at some of
the data being passed around:

argdata was {'sql_delimiter': '\000', 'client': '1', 'pend': '1',
'pstart': '1', 'sql_quote__': }

This is starting to confuse me because simple queries work fine within
Zope, its only the query that I posted in my previous message that seems
to be fowling things up.

I'll keep slagging away until either I figure it out or someone tells me
its not something I've done and that I should submit it to the Collector
:)

Subject: [Zope] DatabaseError: Corrupted data record...
Message-ID: <199903052137.VAA24776@finan.ncl.ac.uk>

Hi all,
Firstly, I'd like to thank everyone for the detailed replies I got to my 'Tough Questions' post.
I'll reply individually to you all and try to answer some of the questions that *I* got asked, but as 'they' say...

"...there is one small problem!" (MPaTHG)

My database has got nuked.

I don't know how it happened, but this is the tail of my serve.errors file

  File "lib/python/OFS/Application.py", line 319, in open_bobobase
    Bobobase=Globals.Bobobase=Globals.PickleDictionary(
  File "lib/python/BoboPOS/PickleDictionary.py", line 159, in __init__
    db=apply(DBType,(),storage_options)
  File "lib/python/BoboPOS/SimpleDB.py", line 221, in __init__
    self.open(file_name,create,revision_time,meta_index,read_only)
  File "lib/python/BoboPOS/SimpleDB.py", line 287, in open
    try: self.index,self.pos=read_index(
  File "lib/python/BoboPOS/SimpleDB.py", line 1365, in read_index
    raise DatabaseError, ('Corrupted data record at %s' % pos)
DatabaseError: Corrupted data record at 1087646

Trying to 'start' the server again just results in the serve.errors file being touched.

As you'll know from my 'Touch Questions' post, I'm a novice in Zope (but I've bought the Lutz 'Programming Python' book, have two more on order and have been reading and rereading the docs all week...so I'm learning fast), but this has me stumped.

I haven't got too far into my Zope 'career' yet, so I won't be devastated if I have to replace the database from scratch (how do you do that by the way?), but I'm sorta worried about the way that all my work seems inaccessible to me now.

any and all help would be ... appreciated.

Okay, now it makes sense.

Is 'client' a reserved variable?

If so, perhaps a warning would be nice if you attempt to use a reserved
variable as an argument to a SQL method.

Argh.. so I got that fixed and now I am getting another traceback when
testing the SQL method!

I can't believe it :)

Here it is:

I need to detect not only whether a list is empty (that's easy with the
#if tag for example), but also whether all of the elements in the list
have a property. In Python, one could do this with something like:

  empty = 1
  for element in theList:
    if not element.hidden: empty = 0
    print element
  if theList and not empty:
    print "no non-hidden elements"

What's the equivalent DTML?  Can one create a variable in DTML?

Can anyone tell I miss my Python when writing DTML? =)

Oh my :-)

I didn't try such a thing before. But because the Zope
database is always only appended to (if I'm understanding right),
you might try to truncate the file upto that offset and see
if it is working again? (please keep a backup :-)

Subject: [Zope] Authentication and Zope.cgi
Message-ID: <199903052211.PAA16445@daikon.tuc.noao.edu>

I'm in need of a bit of clarification about how Zope starts up and when
it decides to do its authentication and why.

I'm running 1.10.2, solaris 2.6, apache, pcgi, netscape 4.07.  When I request
mymachine/Zope/manage   I do indeed get the normal management screen.
I haven't been asked in some time for a password, which suprises me;
the 'access' file exists and (but?) hasn't changed since installation.

I'd really like the root folder to say something other than Zope, so
I added to Apache a second rewrite rule that substitues 'mpg' for Zope
in the two places (restarted Apache), and copied Zope.cgi in cgi-bin
to mpg.cgi .  These two cgi files are identical so they point to the
same /var directory.

If I try   mymachine/mpg/manage  ,  I get an authorization failed box,
and upon clicking 'retry', I get the usual authentication box with
the correct 'access' user entered.  I type in the correct password and
the system fails again ("You are not authorized to use this system.
Username and password are not correct").

So, I'm very curious as to what's going on ... and I wouldn't mind
learning how to change the top of the root name as well.

I try hard to do everything in DTML but ... python is such a breeze.
OTH if you have most of your code written in DTML it is so easy
to create similar products and move them around.

What version of Zope are you using? What OS?  Were you using NFS? MySQL?

Please send *in private mail* me a gzipped tar file (or Zip file) 
containing the Data.* files from your var directory.

Any other thoughts you might have regarding events leading up to this
would be helpful.

Good point.  I should have mentioned that as a quick
recovery, especially if the location is near the end of
the file.

But please send me the file before you truncate it. :)

Hmm. I want to create a variable whose value is given by another value.
Doing:

<!--#with "_.namespace(foo=<!--#var id-->)"-->
<!--#var foo-->
<!--#/with-->

doesn't make it through the parser.  

I've tried adding various quotes to no effect.

I think I'm going to work on understanding ExternalMethods -- this syntax
is not made for me. =)

Why does my ZMySQLDA Z SQL Method die with a KeyError: unhandled message?

Well, I was looking at the code for the MySQLmodule and it appears that it
has problems handling some fields.

This appears to be a limitation of the MySQLmodule.  It currently does not
handle the LONGLONG datatype longer timestamps use.

At least I assume its the LONGLONG that is messing it up.  I haven't
looked into that much detail to be honest.  

I'm not quite sure if this is something that should be included in the
FAQ, or considered a known bug, or submitted to the Collector?

Thanks,

This surprises me, since as far as I can see, one is always asked for password
accessing /Zope/manage. Does netscape 4.07 automatically go through authenticate
procedure?

There are at least two possibility.
1) Misconfigured rewrite rule.
2) mpg.cgi is not altered suitably.
(oh, 1+2 gives the 3rd possibility).

I was in a similar situation a few days ago. Now one of apache virtual host on my
linux box has 1) ordinary apache site tree, 2) experimental(read 'for play') Zope
site under  hostname/Zope/ (through Zope.cgi)
3) public Zope site under hostname/public/ (through public.cgi)
If this is similar enough to what you want achieve and you are desperate enough,
just mail me your rewrite rule and Zope.cgi & mpg.cgi with sensitive parts
altered suitably. But be aware that I am new to rewrite rules and pcgi
world(hence if you are desperate enough).

This is easy. Just edit BOBO_REALM (NAME?) in your *.cgi file.

LEE Kwan Soo.

ps.  my Zope's have their own var/Data.bbb but you want your Zope to point to the
same var/Data.bbb. Oh this seems far beyond the capacity of mortal being. If you
really want need this setting, I guess, the easist way to achieve it is getting
Zopal blessings from DC(i.e. make a consulting contract with DC).

Subject: [Zope] underscores in Z SQL Method
Message-ID: <x1jhfrzcy2z.fsf@unhinged.engr.sgi.com>

Hello all, I recently discovered Zope and am diving right in.

I have a Z SQL Method with the following Query Template:
---
select *
from rw_ProjectData 
where _id = <!--#sqlvar projID type=int-->
---

when I test it, I get the following:
---
Sorry, an error occurred.

Traceback (innermost last):

I'm guessing that the parsing of the tokens picks up on underscore
('_') even outside of the DTML tags. Does anyone have a solution or
workaround?

Ouch!, what we do is save the word docs as RTF. A free program (written in
Omnimark) called RTF2XML then trundles through it and creates well-formed
and valid XML. I then pass it through another Omnimark program that I wrote
that turns it into XML that is more suited to what we want.


>I've been awfully interested in XML in the last few days.  Can you

Background:...
PHP is a (non OO) server-level scripting language, usually delivered as an
Apache module, that has it's roots in C, but with some of the arcane bits
removed. It's database integration is very good. The authors have recently
built the (almost XML-industry standard) parser Expat into it.
...

From my point of view, having the XML parser in PHP meant that (a) I didn't
need to call Perl CGIs (with all that overhead), (b) I'd understand the code
a bit (I *cannot* do Perl!), (c) there might be a performance boost from
having the parser in the Apache Module and (d) I'd be able to map XML
elements such as <topic> ... </topic> into HTML <div> ... </div> tags or RTF
control codes (all of which would be read from a user-defined database) -
thus leading to the 'Holy Grail' (ouch!) of being able to render the
documents into whatever form the end-user wanted. As well as that, using XML
means that I can select all <topic> .. </topic> tags that match a certain
criteria (eg, all first-year study guides that mention cell biology) from
*all* our study guides and create a 'composite' document that would be
passed through the XML 'converter' to get custom HTML and RTF docs.

Of course, once I 'got into' XML I found out that just having the Expat
parser around didn't necessarily mean I was going to get all that for
free...ie how 'do' you 'search' an XML document to get those matched <topic>
tags (and possibly their children). Enter XQL and it's friends, DOM and XSL.

XQL (Perl module based on a W3C recommendation) works, but it's slow. 

In short, I was at an impasse. The level of work needed to incorporate XQL
into PHP (as a CGI) or (gulp) rewriting it as PHP was just too much.

I installed the XML-Config product for Zope and my appetite was whetted. I
read about the XML-sig and downloaded the XML-0.5 toolkit from python.org. I
tried one or two examples out ... and my jaw literally fell open. By the
time I'd looked in the 'dom' directory I was almost gibbering. This was
something I felt I might be able to understand (and definitely use).

Ooops...I'll shut up as I'm waay of topic.

No, but I've spent the last week muttering 'ok, I can use UserDB to
authenticate against our StaffDB and allow per-user access to the file
upload area', 'yeah, should be able to rewrite my PHP Multi-Choice Question
engine in this DTML gubbins', 'ok, I'll pull in the Perl script that does

Simply this: 
Zope seems to do just about everything I need (which is basically to provide
a *framework* for the Electronic Curriculum - others will fill in *and
manage* the content). I can then concentrate on providing features that
people need and 'rolling them out' to the users of the systems, confident
that they will integrate into the whole system. 

I think it's a paradigm-shifty thing more than anything else. Everyone in
our group *knows* that an .htaccess file allows access to the files in that
directory. They all have at least a basic grasp of CGI programming and all
recognize the mapping between files in a unix file structure and their
representations as web pages. People using Zope will have to break that
habit of logging in to change a file ('cos it ain't there!).

(for the time being, I've desubscribed from the PHP-lists to give me more
room to think!...)

Message-ID: <3.0.6.32.19990306180733.009318b0@hito.eccosys.com>

I think there must be an easy way around a little trouble I'm having, but
it's had me stumped for a few days and I can't find any mention in the
list/docs.

From a dhtml method I want to access a subfolder's sql methods, which is
easy enough using <!--#with SUBFOLDER--> <!--#/with-->. The problem is,
because of the amount of methods involved and in order to keep things
flexible I want to add the <!--#with--> to a standard_header, and the
<!--#/with--> to a standard_footer. Of course, Zope nixes this. So I was
hoping there was an end-run around this dilemna - some other way to give
access to subfolders. 

I've tried including the opening and closing WITH's in the same document
surrounded by IF's with no luck, and have been wondering if there's a way
to set a folder property to accomplish this...

You cannot nest DTML but you can use _[] to access the namespace. For
instance you could do:
<!--#with "_.namespace(foo=_['id'])"-->

I too miss Python when working in DTML.  But in this case, I think that the
following will help:

Subject: [Zope] Creating Zope a zope application
Message-ID: <19990307130236.A532@RaVER.duck.org>

Hi!

I'm reading 'A technical introduction to object publishing with Zope'.

The doc says 'Creating a Zope application is simply a matter of creating a
regular Python module containing the objects to be published, and placing
this module along with some Zope-provided support files in the appropriate
place on a web server'

The doc continues to say that the zope documentation covers this prosess,
but I'm not able to find it. So my question is - what are those
zope-provided support files, and where am I supposed to place those file
along with the python module that I've created?

Does this have any ominous implications for server performance? I believe it

We can discuss this now, but in a short while it won't really matter.
Zope as we know it now is not 'multi-threaded'.  The real issue
concerning Zope is one of concurrency, since the 'threading' of requests
is ussualy created by the web server (Apache using multi-processes or
Medusa (ZServer's) use of select(), neither of which use actual
'threads').  There are two areas that we are working on to make zope
concurrent.

The Database:
	There is a new version of BoboPOS, called BoboPOS3.  It is
currently alpha.  BoboPOS3 supports concurrent processes opening,
reading and writing the Object Database.

'Concurrifying' Zope:
	Concurrent programs have to be careful about some issues.  In
particular, the use of global data.  These can sneak in on you in wierd
ways.  For example, in the regex python module (yes, regex has been
depreciated for re, but for now regex is faster) certain uses of
compiled reg expressions don't work when two 'threads' enter the same
expression.  Also, there is an issue about passing mutable objects as
default arguments to methods.  To be truely thread safe, default
arguements need to be immutable, or mutable arguments can only be used
in immutable ways.

These are, as you said, developer issues.  Product developers have to be
careful not to block Zope for long periods of time.  People in the
'install and use them' scenario should not use these types of Products
unless they are sure the block times are low, and product developers
should be very, very careful about moving their software out into the
world if the product blocks.  It should be made clear to the user that
this software could stop up the whole works.

Why is won't matter soon is because we are working on making Zope fully
concurrent.

Advice needed, opinions wanted.

I have a situation where there is a group of users with both a private
space and a public space. The users homepage is considered private with the
public space where all anonymous viewable docs are held. I have two
thoughts on how to do this, Zope is capable of either method, I'm curious
which method everyone else thinks best, and why.

First method;
community folder (contents public viewable by permission)
     user_folder (contents not public viewable by permission)
	users manage page (not public viewable by aquisition)
	users public folder (public viewable by permission)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by aquisition)

Second method;
community folder (contents public viewable by permission)
     user_folder (contents public viewable by aquisition)
	users manage page (not public viewable by permission)
	users public folder (public viewable by aquisition)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by permission)

Both have advantages and disadvantages, either way I end up with on - off,
off - on, in the permissions hirearchy. Anyone have a good argument for
either method?

Subject: [Zope] Why doesn't this loop over files?
Message-ID: <v04104422b3094ee5414d@[128.240.198.13]>

Hi,
I've d/led the ZopeDemos folder, installed it and started learning 
more about Zope, but there's something happening that I'm not sure 
about.

The 'looping' example doesn't seem to iterate correctly over new 
additions to the folder. The DTML is here:

<!--#in "['Document','Folder']"-->
<!--#if "objectValues(_['sequence-item'])"-->
   <H3>Objects of type <!--#var sequence-item--></H3>
   <TABLE BORDER=1>
   <TH>Id</TH><TH>Title</TH>
   <!--#with subFolder-->
      <!--#in "objectValues(_['sequence-item'])"-->
        <TR><TD><!--#var id--></TD>
        <TD><!--#var title--></TD></TR>
      <!--#/in-->
   <!--#/with-->
   </TABLE>
<!--#/if-->
<!--#/in-->

If I create a new DTML method or document in the folder 'subFolder', 
it isn't recognised. I've even copy/pasted the documents that do work 
into the subFolder with no joy. Curiously, new folders *are* 
recognised.

My Question is: What's preventing Zope from reading *all* the 
Documents in the subFolder?

This would be the core of my first real application in Zope (a 
resource upload/download facility for staff here) so any advice would 
be appreciated.

thanks
tone.

Thanks for the informative answer Michel. Look forward to seeing the

I don't know if my critiques will be all that useful (being a Zope 
newbie), but hopefully this will help a bit.

Yes.

Definitely. We have dozens and dozens (eventually hundreds) of files 
(QT movies, PowerPoints, Word Docs and the like - the mean size is 
about 600k-1Meg, but we have quite a few monsters at 6-7 Megs).

This would be excellent news for us.

Does this ensure that MIME types are kept with the document, so that 
'clicking' on its link will ensure that the correct helper 
application is invoked?

Cheers,

Ad-hoc Zope FAQ version 0.1.1

Note on the categorizing of this FAQ:

    This FAQ is a FAQ in progress. It is uncompletely unstructured;
    unrelated questions are mixed haphazardly. If you feel the calling
    to help categorize the FAQ into sections, or if you'd like to
    maintain a particular FAQ section, please mail to the ZDP
    list. Thank you in advance!

Note on the use of StructuredText:

    See the (currently) first FAQ entry for information on how to
    render this FAQ into HTML using Zope. For more information on
    StructuredText see::

        http://www.zope.org/Documentation/Reference/StructuredText

    but this link is currently not completely up to date; see the
    comments in 'lib\python\StructuredText\StructuredText.py' for the
    current documentation.

* How do I render the Structured Text FAQ into HTML cleanly? (in Zope)

    When including Structured Text (STX) from a DTML Method into
    another Document with the 'fmt="structured-text"' attribute, it
    will be quoted twice. This is because the '__str__' method of the
    'DocumentTemplate.HTML' class automatically quotes its HTML when
    called.

    You can work around this by calling the STX document's
    'read_raw()' method to get the unquoted version.

    This way we can use unquoted Structured Text examples in our FAQ::

        <!--#var "FAQ_Document_stx.read_raw()" fmt="structured-text"-->

    Note that if the STX comes from a property the 'read_raw()'
    workaround is not needed.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

    Another possibly is to use '_.getitem()', like this::
   
        _.getitem('sequence-item')

    The difference is that the first renders 'sequence-item' through
    DTML, whereas 'getitem()' does not; it returns the raw value of
    'sequence-item'.

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their
names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like 'REQUEST.form', 'REQUEST.cookies' and even
    'REQUEST' itself. Just call the 'items()' method of the
    dictionary, and the #in tag will provide a 'sequence-key' and
    'sequence-item' variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
          <!--#var sequence-key-->:<!--#var sequence-item--><BR>
        <!--#/in-->

    Use 'REQUEST.cookies.items()' for all your cookies, and
    'REQUEST.items()' for all 'REQUEST' variables, including CGI
    Environment variables.
    
    If you don't mind the format, you could use '<PRE><!--#var
    REQUEST--></PRE>' as a shortcut.

* What is a Principia Draft?

    A Principia Draft is a special copy of any Zope object that is
    invisible to visitors of your site. You can make changes to this
    copy, and grant access to outsiders to view your changes (or work
    along with you). When all changes are done, you can approve all
    the changes, or discard them. Approving will make the changes
    permanent and visible to your audience. However, currently Drafts
    can appear to be broken.

    To add a draft, choose Principia Draft from the popup menu and
    click 'Add'. Next, you will have to supply an ID for the Draft,
    and specify on what base object you are going to work. Clicking
    'Add' in this screen will create the Draft for you. Next, you will
    have to specify who will have access to the Draft.

    Here the problem starts, because of the way Drafts are
    managed. First, a Draft doesn't acquire any users from its parent,
    so you will have to add anyone who has to have access explicitly,
    even if they have already been access to a parent Folder. But the
    biggest problem is that you can't reach the UserFolder and
    Approval screens via the management screens. This will make a
    Draft a bit harder to use, but it still is workable.

    This second problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately.  Principia Drafts made use
    of the call to 'title_and_id' to insert links to its UserFolder
    and Approval management screens. As this now doesn't happen
    anymore, you will have to type in the URLs to the screens
    yourself.

    You can reach the screens calling the Draft object's
    'users__draft__.manage_main' and 'manage_approve__draft__'
    methods. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

    So, the next step is typing in the URL to the Draft's UserFolder
    management screen, and adding all users that should have access to
    the Draft. These users can now edit and view all changes made to
    this Draft.

    When done, you go to the 'manage_approve__draft__' management
    screen, and approve, or discard the changes.

* How does my Folder Product load default documents?

    Create a list of tuples containing filenames (without '.dtml') and
    title pairs::

        self.defaultDocs = [
            ('index', 'NotMail'),
            ('address', 'Address Book'),
            ('attach', 'Attach a File'),
            ('composer', 'Compose a Message'),
            ('contact', 'Contact Developers'),
            ('search', 'Search Your Mailboxes'),
            ('results', 'Your Search Results'),
            ('folder', 'Mailbox'),
            ('message', 'Message'),
            ('help', 'Help'),
            ('lookup', 'Lookup Users'),
            ('standard_footer', 'Standard HTML Footer'),
            ('standard_header', 'Standard HTML Header'),
            ('noto', 'Message must have at least one recipient.'),
            ('reminders', 'Your Reminders'),
            ('save', 'Save Message'),
            ('logout', 'You have been logged out'),
            ('GPL', 'The GNU General Public License'),
            ('sentmail', 'Mail was sent')]

        # Then iterate over them and create each one

        for id,title in self.defaultDocs:
            try:
                self.defaultDocFile(id, title, id)
            except:
                pass

        # defaultDocFile is a handy little function:

        def defaultDocFile(self, id, title, file):
            f=open('%s/Products/NotMail/%s.dtml'
                   % (SOFTWARE_HOME, file))
            file=f.read()
            f.close()
            self.manage_addDocument(id, title, file)

    When you are debugging your DTML, it's a pain to keep deleting and
    creating new instances of your object in order to load the new
    dtml files off of the disk. This function comes in handy::

        def refresh_docs(self, REQUEST):
            """ refresh documents from disk (for debug purposes) """
            
            for id,title in self.defaultDocs:
                try:
                    self._delObject(id)
                except:
                    pass
                try:
                    self.defaultDocFile(id, title, id)
                except:
                    pass
            return self.manage_main(self, REQUEST)

    Then, assuming your object has an attribute 'debug' you can define
    some DTML like so in your manage_main screen::

        <!--#if debug-->
        <p><a href="refresh_docs">Refresh Documents from disk</a></p>
        <!--#/if debug-->

* How do I add management tabs to my folder sub-class?
   
   If you subclass 'OFS.Folder.Folder' to build a folderish object,
   you may want to keep around the old Folder management tabs, but add
   some of your own as well. This can be done by mucking with the
   Folder class 'manage_options' attribute. One problem is that you
   might want your own custom 'manage_main' but the FolderClass uses
   'manage_main' for displaying the contents of the folder. Here is
   what I did for my EMarket product.
   
   By examining Folder's manage_options::
   
       for option in Folder.manage_options:        
           print option 

   We get the following output::

       {'label': 'Contents', 'target': 'manage_main', 'action':
'manage_main'}
       {'label': 'Properties', 'target': 'manage_main', 'action':
'manage_propertiesForm'}
       {'label': 'Import/Export', 'target': 'manage_main', 'action':
'manage_importExportForm'}
       {'label': 'Security', 'target': 'manage_main', 'action':
'manage_access'}
       {'label': 'Undo', 'target': 'manage_main', 'action':
'manage_UndoForm'}
       {'label': 'Find', 'target': 'manage_main', 'action':
'manage_findFrame'}
   
   Notice that the "Contents" tab calls Folder's manage_main attribute.
Just
   rename that in your sub-class with something like::
   
       manage_contents=OFS.Folder.Folder.manage_main
   
   and assign that to a different tab. Here is the beginning of the
MarketItem
   class from the EMarket product::
   
       class MarketItem(OFS.Folder.Folder):
           """A MarketItem """
   
           # Specify a name for the item type:
           meta_type='MarketItem'
   
           # Specify a relative URL for the icon used to display icons:
           icon='misc_/EMarket/marketItem'
           
           # rename Folder's manage_main to manage_contents
           manage_contents=OFS.Folder.Folder.manage_main
  
           manage_main=HTMLFile('marketItemEdit', globals())
           manage_image=HTMLFile('marketItemImage', globals())
   
           # Specify definitions for tabs:
           manage_options=[
               {'label':'Attributes', 'action':'manage_main'},
               {'label':'ImageUpload','action':'manage_image'},
               {'label':'View',       'action':''},
               ]
   
           # add in the options from the Folder class.... change
           # the 'action' for Contents to 'manage_contents' 
           for item in OFS.Folder.Folder.manage_options:
               if item['label'] == 'Contents':
                   # be sure to use a *copy*
                   manage_options.append(item.copy())
                   manage_options[-1]['action'] = 'manage_contents'
               else:
                   manage_options.append(item)

Subject: [Zope] '~' in StructuredText links?
Message-ID: <14051.53317.19816.135841@cuckoo.EMBL-Heidelberg.DE>

Hi Zopists,


using StructuredText 
 ($Id: StructuredText.py,v 1.11 1999/02/08 18:13:12 klm Exp $)
for content generation, I find that I can't include tilde (~) characters in
hyperlinks, i.e. a  string like 

	"brabbel":http://www.embl-heidelberg.de/~ehrlich.

is not mapped to 
	
	<p><a href="http://www.embl-heidelberg.de/~ehrlich">brabbel</a>.</p>

but output as literal 

	<p>"brabbel":http://www.embl-heidelberg.de/~ehrlich</p>.
				
I tried to fix StructuredText,StructuredText.__init__ by inserting '~' into
the gsub statements. No success whatsoever...

As I couldn't find this entry neither in the Collector nor in the archive,
I wonder whether somebody has a patch sitting somewhere?

Cheers,
	Lutz

I just ran into this error. When I did a SELECT * on joined tables it would
give the error but if I named the fields I needed it worked. I played with
it a little and got the error again when I named a field that ended in _num
in the SELECT. I have four such INT fields that I don't need, they are used
by the JOIN, and have _n counterparts in the JOINed tables (see SQL below).
As you can see my SELECT list is long and it would have been nice to just
use a * since I need almost all the fields.

Everything works fine in MySQL client but from Zope I can produce that error.

Maybe there is some conflict with the *_num names. What are your field names?

SELECT
  sonum,cust_name,cust_n,description,kickoff,delivery,
  comment,partnum,pm_n,pm_initials,cad_n,cad_initials,

I was able to find a work around.  The problem was the handling of
the TIMESTAMP datatype by the MySQLmodule.  It doesn't know how to handle
a long timestamp unfortunately, so you'll want to retrieve it as a UNIX
timestamp or as a formatted date using one of MySQL's many date functions.

The other thing is that I doubt it handles double long integers since
AFAIK Python doesn't handle these without an extension module.

If your query is returning any of these you'll most likely get this
response from Zope...

   It sure does:

Python 1.5.2b1 (#2, Jan 18 1999, 11:01:20)  [GCC 2.7.2.1] on freebsd3

    Spiffy, eh?  I'm pretty sure it's arbritrary-precision, which means you can
make numbers as large as you have memory for.  Or is this not what you
mean?

Hey, I'm glad you proved me wrong :)

It looks like there is a limitation in the MySQLmodule when handling
MySQL's LONGLONG datatypes that could probably be corrected.

I may take a look at this later, but I am thinking I may just store UNIX
timestamps in my database since this is more portable across databases
anyways.

But anyway, this may be a FAQ item as I'm sure other people may run into
it.

Hi All,

I fetched FAQ tool from "http://www.zope.org/WebReview/" but the 
archive contain only :

* __init__.py

*version.txt

*Product.dat


No, FAQ.py file. Strange no. Thus, this is maybe why I cant view 
Faq in the list of objet in Zope!!

Message-ID: <v04003a10b309c53d7c44@[192.168.1.190]>

Here is a strange one -- I am getting an L on the end of integer numbers
from MySQL. (They are INT not BIGINT!) It didn't happen in 1.9, and it
doesn't happen with methods that I created in 1.9 and moved to 1.10.2 (I
think).

In <!--#var--> I have to use fmt='%d' to get rid of it.

I also had a problem when I tried to use one in a redirect:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(num))"-->
produces:
http://server/dir/file_html?num=53L
which causes an error.

I got around that by adding an int function:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(_.int(num)))"-->


Has anybody else experienced this problem? Having to add all this extra
code is driving me crazy!

While this may seem strange, this is in fact the normal contents of a
Product distribution file for a "levered product". When you build a product
through the web inside the control panel, these are the normal files Zope
creates inside the product distribution.

>Thus, this is maybe why I cant view 
>Faq in the list of objet in Zope!!

Unfortunately this is not the case. The reason you can't use the FAQ is
that there is a bug in Zope which keeps some people from being able to use
levered distributions. As discussed on the list, it appears to be related
to zlib compression.

We are aware of the problem and are working to solve it.

Thanks for your patience.

-Amos

P.S. If you're curious about a bug, you can try searching the Collector.

http://www.zope.org/Collector

In this case a search under "lever" or "faq" would turn up the existing bug
report for this problem.

No real issues, just d/l the source release and try compiling Zope.  I'd
recommend having Python 1.5.1.  To build the source release to use the
built in simple web server, try:

'/usr/local/bin/python1.5.1 wo_pcgi.py'

to use with Apache (Note, d/l Zap and look at it's .conf file)

'/usr/local/bin/python1.5.1 w_pcgi.py'

Change the command line to reflect your python binary.

Check out, I think, INSTALL.txt in the doc directory.  All the C is
ANSI, and python is python (grin) so you shouldn't have a problem.

Hi Guys:

I think I've nailed the problem that was keeping people from using the FAQ
Tool and levered products in general under windows.

I'd love some confirmation that this does or does not solve people's problems.

The fix is to open the product.dat file in 'rb' mode. To do this, change
line 420 of lib/python/App/Product.py to:

        f=CompressedInputFile(open(home+'/product.dat','rb'),name+' shshsh')

Again, let me know if this doesn't work for you.

This fix works for me (lline 407 in my Product.py) 

HOWEVER ... you must delete the FAQ product from the control panel, 
then restart ZServer for this fix to take effect. Apparently the old FAQ in 
bobo inhibits re-reading of the product.dat file.

There's a bug in the code, something I noticed when I was playing

About the bug and the fix:
the bug was due to the statement <!--#if
"objectValues(_['sequence-item'])"-->
looping over the current folder, not the subFolder which it should be.
By moving the "with" statement to enclose it (see line 002), the
statement <!--#if "objectValues(... now loops over the objects inside
the folder named "subFolder".

I don't know who is maintaining the ZopeDemos product (or if it's
being maintained at all), 
but I hope he/she takes note of this and posts an update. 

Hope this helps.

PS. I'm playing around with the Confera product (making it more
slashdot-like) but I know it's
not "officially supported" by Zope/DC -- so who's maintaining it? I
have some detailed questions about the code (but I don't know if it's
off-topic for Zope/Zope-dev).

The new version of the FAQ has been uploaded at:

The format has been changed after Martijn Pieters suggestions. It now
supports structured-text as the default format. Actually it was pretty
easy to upload Martijn Faassen's FAQ.

The e-mail uploading option has been dropped. If you want to submit a
FAQ entry you can do it over the web. Also the XML DTD has been changed
slightly. A typical entry would be:

A few days late for this thread, but I just ran into the problem.

After reading through the thread, and poking around the MySQLmodule source
a bit.  I thought I'd see what happened if I changed the unhandled to long
in the MySQLmodule...
At line 440 in MySQLmodule.c, change 'unhandled to 'long', or as a
unified format diff:

So far, no problems.

Ok, I'm stupid. I realized right after I sent this, that I forgot a

Something I'm just curious about...

where <!--#sqltest name column=column_name type=column_type-->

VS.

where column_name = <!--#var name-->

Is the only advantage of using the first (sqltest) the type checking? I
can't find any other obvious advantages.

Butch,
Thanks for the reply - but this doesn't work completely either. I can 
add folders and delete them and the changes made show up in the 
listing, but adding documents (both documents and methods) has no 
effect. If I delete the *original* documents created by the 
installation, they show up as being gone, but even a copy-paste of 
the original documents doesn't get any new documents/methods etc. to 
show up.

Am I doing a dumb newbie thing here? (I *do* have a folder called 
'subFolder' btw).

many thanks
tone

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <19990309084120.83ca0fd9.in@mediamail.telinet.com>

Hi all,

I have been using python for years, and zope for a few months now (lovely),
ZServer for weeks, but Windows NT? Not long enough to understand the
differences between services and ordinary process (give me a break, I am
heavily from a Un*x background) :-).

I know when I installed the binary version of Zope on the windows machine
here it gave me a service in the services list which I can activate on
startup. However, I am betting that this runs the ZopeHTTPServer, not the
ZServer which I got as a separate download. I have everything working just
lovely with the ZServer now, but it needs to be run as an NT service (and
respond to start and stop signals, etc) at which point I freely admit my
own inadequacies in this area.

Now my question. How can I do what I need to do. Is it simply a case of
redirecting a python 'shell' file used by the service to the start.py in
the ZServer module, or is there more to it? If it is this simple, which
python 'shell' file do I use? If it is not this simple, can someone send me
basic instructions on how to do it (why is NT like this - give me an
rc.local file any day - I know where I stand with that stuff).

Thanks in advance.

Dick

Can you submit this problem you noted to the Collector as a

Zope-dev is the place to ask specific questions about Zope's API and
Zope Product Authoring.  Go ahead and ask your questions, the unsuported
just means we can't make any guarantees or commit company resources to
it, but if your question happens to use Confera as it's basis all the
better.  Someone out there might have the answer.

Hi All,

The DTML Example folder has been updated. I've incorporated the fix below,
but the reason that new documents were not showing up is that the page was
looking for the wrong 'meta_type' for objects in the subfolder. Up till the
last release, documents had a meta_type attribute of 'Document', but now
documents either have 'DTML Document' or 'DTML Method' as their meta_type.

Tony's problem was that Zope was correctly respecting the meta_type of the
'old' Document objects included with the demo, but any new documents added
afresh were being created with the 'DTML Document' or 'DTML Method'
meta-types, which were falling through the objectValues 'sieve'.

Here's the new version...

Cheers,

Andy.

I haven't played with it too much but I think that Zope handles undefined
variables properly if you do the sqltest.

ie.

where <!--#sqltest name column=column_name type=column_type-->
and <!--#sqltest name2 column=column_name2 type=column_type-->

will work if name2 is not defined.

It also handles the quoting and SQL syntax (such as doubling single quotes).

My guess is that you created your original database in Zope-1.9 and then
moved everything into Zope-1.10. If that is the case then you need to
replace
<!--# in "objectValues(['Document'])"--> with
<!--# in "objectValues(['Document','DTML Document','DTML Method'])"-->
or something to that effect.

Not quite.  ZopeHTTPServer is a console app just like ZServer.  The
service is a PCGI-like thing that runs Zope as a service, listening for
named pipe connections from something that is run as a CGI by the web
server.

ZServer is still at alpha 2 so it's premature to focus on things like
how it is packaged.  I *think* we have all the issues figured out and
the next release, perhaps this month, will be a beta1.  Until we get
into beta, we'll have to hope that someone in the community packages it
up as a service.

One issue off the top of my head is integration with the NT Event Log.

Absolutely...  we ran into some situations where the SQL was so dynamic
potential security problems arose.  sqltest and sqlvar are designed to
reduce that exposure.

Additionally, we've found a very common rhythm where a search UI might
expose all of a large percentage of the available data elements in the
RDBMS.  Using sqltest lets the user not specify one or more parameters
without a lot of messy <!--#if --><!--#/if --> stuff in the SQL Method.

I'll correct myself here. I was thinking of the <!--#sqlgroup ...--> tag. I
don't know what <!--#sqltest ...--> does that <!--#sqlvar name--> or
<!--#var name fmt=sql--> won't do...

I meant to bring this up in my earlier post -- this tag too, is used to
simplify what could be a terribly complicated SQL Method given an
indeterminate number and list of search criteria.

With this tag you can permit an arbitrary arguments to be supplied
connected with your predetermined ANDs and ORs

This one tag has, in the past, reduced may SQL Methods into one --
natural maintenance savings.

A _very very_ nice feature of #sqltest is the 'multiple' feature.  For
example:

SELECT * FROM inbox
WHERE <!--#sqltest doc_status type=string multiple-->

If doc_status is passed in as a single value, like "foo", the SQL statement
will be rendered as::

SELECT * FROM inbox
WHERE doc_status='foo'

BUT!!! (this is where it gets good), if doc_status is passed in as a
list/sequence, like ["foo", "bar", "drop", "ship"], it will be rendered
as::

SELECT * FROM inbox
WHERE doc_status in ('foo','bar,'drop','ship')

This is an _extremely_ handy feature of #sqltest.  Prior to #sqltest, doing
the above might be like:

SELECT * FROM inbox
WHERE doc_status in (
 <!--#in doc_status-->
 '<!--#var sequence-item fmt=sql-->'
 <!--#else sequence-end-->,<!--#/else-->
 <!--#/in-->)

(#else used to be used where #unless is used today).  The above code also
always required doc_status to be passed in as a sequence.  #sqltest is
smart enough (I believe - i've never been bitten by this) to detect the
difference between strings and lists.

I've used #sqltest with multiple many times with Acquisition where a folder
property would define part of a SQL statement.  That property in some cases
would be a single value, in other places it would be a tokens or lines
property.

So, in otherwords, you get the type checking, the multiple, the optional,
etc... with #sqltest that you don't get otherwise.  About the only problem
is that #sqltest currently doesn't do not-equals or "not in (...)".

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?

I bet your using a DTML Document.  Try using a DTML Method.  The reason
why the tree tag renders nothing for the DTML Document is because DTML
Documents are not containers of other objects, they are objects to hold
DTML content.  DTML Methods are (and this is the suble thing) *methods*
of the Folder object that contains them.  They are not 'objects' in the
same sense of the term used for DTML Documents (I can hear Jim saying
now "*everything's* an object").  Because Folder objects *are*
containers, the #tree tag used in a Folder's DTML Method will render the
contents of that Folder.  Hadar's example is a little outdated, it is
based on 1.9, in which DTML Documents didn't exist, and all Documents
were DTML methods.

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <006501be6a52$b0bbe900$fa01a8c0@rogue>

I currently have ZServer running as a service on two machines using the
srvany.exe tool from the NT resource kit or from MSDN.  Essentially srvany
is the actual service and then you tell it via registry settings what other
program you want to run.  It works good enough for me for the time being.

The only problem is that the service stop message does a hard kill on the
ZServer process so any last second updates to the Zope DB might be
fragmented if it wasn't finished writing, but with the way the DB works at
least the DB will still be usable.

I am out of the office right now so I can't provide step by step
instructions right now.  There is a .doc file that comes with srvany.exe
that I followed.  I specified that Python was the executeable to be run by
srvany, the ZServer directory is to be the CWD, and that the command-line
should be start.py.  Worked first try.

Of course the right thing to do would be to integrate native service
capabilities into ZServer itself via the win32api packages.  That way
ZServer could shhutdown gracefully and could send meaningful things to the
event log.  But srvany is good enough for alpha level, non-production
servers.  And I havn't had any problems to speak of dealing with running it
as a service.

I have a nifty system whereby each individual I add to a database
automatically gets a personal directory and password. One of my users
has come to me with a problem. He can add images to his directory, but
cannot subsequently edit the image (i.e. open the image's manage screen)
as it complains about lack of permissions. The security role he has
contains all the image related options I see. He can delete it, btw.
This is not an immediate issue, but I do wonder why the permissions
don't seem to be working in a sensible manner. Why should he be able to
add images, but not manage them? Are there extra 'image manage'
permissions? If so, where do I find them?

Message-ID: <36E56988.CEF76199@pop.vet.uu.nl>

Zope FAQ 0.2 - About this FAQ and the Zope Documention Project

* What is this FAQ?

    This FAQ is a project of the Zope Documentation Project, and aims
    to answer any (or at least lost) questions you might have about
    Zope and how to use it.

* What is the Zope Documentation Project?

    The Zope Documentation Project (ZDP) is a community project of
    Zope users that aims to create documentation for Zope. The first
    goal of the ZDP is the creation and maintenance of an extensive
    Zope FAQ, later on other documentation will follow.

    We welcome everybody to contribute; for instance by sending in
    questions and answers for the FAQ.

* Where is the rest of this FAQ? 

    The Zope FAQ has been split into separate sections. If you are
    reading this on the ZDP mailing list, you should see the other
    documents posted as well.

    If you are reading this on zope@zope.org or zope-dev@zope.org, you
    will only see this message. The Zope FAQ is under development. It
    is probably already useful, but because I don't want to spam
    everybody you will have to look at the ZDP list to see the rest of
    the FAQ. Everyone is very welcome to join the ZDP list. 

    You can also wait until the ZDP has its web infrastructure going
    and the FAQ is published on the web. This will hopefully be very
    soon; we're working on it.

* How do I contribute?

    The Zope Documentation Project has its own mailing list
    (zdp@zope.org). You are encouraged to use this list for all ZDP
    related communications. Please do not send your messages (such as
    FAQ contributions) to Martijn Faassen (the current FAQ maintainer)
    if your message can be sent to the mailing list instead.

* How do I join the ZDP mailing list?

    You can subscribe to the ZDP mailing list by using the page::

        http://www.zope.org/mailman/listinfo/zdp

    Thanks in advance for your contributions!

* Are there other Zope-related FAQs?

    Yes, there is the "Zope Questions and Answers" at::

        http://www.zope.org/Information/QA/

    This is maintained by Digital Creations; currently it is the best
    place to look if you are brand new to Zope.

    That said, Paul Everitt of Digital Creations has kindly
    contributed the Zope Questions and Answers to the ZDP (or vice
    versa; the ZDP is contributing to the Q&A). The ZDP plans to merge
    the two FAQs shortly.

* What is Structured Text and what does it have to do with this FAQ?

    The FAQ is (currently) written in Structured Text, so you may very
    well reading the FAQ in Structured Text format (the double colons
    and the indented paragraph structure give it away). If you are
    just reading this FAQ you shouldn't worry about it. 

    If you plan to contribute to the ZDP we'd prefer it if your
    contributions were written in Structured Text, however. For more
    information see the Structured Text section of this FAQ.

* What are these FIXME comments I see scattered through the FAQ?

    If you are reading the ZDP mailing list or its archives, then it
    is the FAQ's editor (or possibly a contributor) who is not
    entirely sure about some details on Zope, and is asking people on
    the list to help figure it out.

    If you are reading this FAQ somewhere else, then oops, they don't
    belong there. Please send a message to the zdp@zope.org list
    telling us about it, and thanks!

* What other sections does this FAQ have?

  We currently have sections on:
  
      o DTML
 
      o Zope Administration

      o Structured Text
 
      o External Methods
   
      o Builtin Products

      o Product Development

I have a problem with authorization under Apache 1.3.3
I can go to introductory screen but I can't get to ./manage screen. I
get Athorization failed, and when I pres cancel I get the traceback
below.

I have put the lines (with modification reflecting my placement of
Zope.cgi) from doc/WEBSERVER.txt at the top of my srm.conf file. I
wasn't sure where to put it, since according to Apache documentation the
directive is not inherited. Later I copied those lines to Virtual WWW
section of www.sol.cz but to no avail.

What does the line "Zope configuration maps /Zope/ to the Zope.cgi cgi
script" mean? I thought that all I need to do is put Zope.cgi in my
cgi-bin, put the above lines into srm.conf, and restart Apache...

You can try it on http://www.sol.cz/cgi-bin/Zope.cgi. name is superuser,

Subject: [Zope] Root Folders and Names {Manager's Guide Update}
Message-ID: <02c001be6a6d$a24716e0$0201a8c0@hawkeye.bob.oc>

* How do I "name"  the *blank* root folder?

This is the same folder that is named "Plutonia" in 
the Zope manager's guide. 

Maybe the root folder has no name so
that if I go to  http://www.bob.com/  the 
"Folder at /     " will present index_html 
to requesting browsers.

If I did name it "plutonia" would it be accessible
both as
http://www.bob.com/   and as
http://www.bob.com/plutonia  ?

So maybe I don't need to "name" this root
folder.  If so, then the Zope manager's guide needs
to be clearer. In the fourth paragraph on page 12 
it says:

"...presuming that your ZOPE is installed at 
http://your.place.com/Objects and it's management
screen is at http://your.place.com/Objects/manage"

This does not follow through the document.
There is no folder named "Objects"

Maybe the document should say:

http://plutonia.com/ and it's management
screen is at http://plutonia.com/manage"

And to manage one of the three departments
used in the examples, say for 
example "News" then:
http://plutonia.com/news/manage"

Other notes on this issue: 
Timothy J. Grant asked:
"...My problem is that my Root folder in Zope has 
no name, and it appears that FSIMPORT requires 
a folder name for it to work."


No response was found to this post on 
the ZOPE list.

I've gotten Zope up and running on my IIS/NT server. Right now I can access it 
through www.myserver.com/cgi-bin/zope.exe. Is there any tricky way to get it to 
run as www.myserver.com/zope? including www.myserver.com/zope/folder/object?

Can you do that with Apache on NT?

I would use ZServer but I need to also be able to run Perl CGI scripts.

Right now you can't. And you don't need to. The "name" of the root folder
is simply the SCRIPT_NAME your webserver uses to access Zope. By default in
ZServer and ZopeHTTPServer this is an empty string, since they both
normally server one published module, though they both can server multiple
published modules.

So, you can give your root folder a title, but you can't use Zope to change
how your web server calls Zope. Do this with your webserver. In the case of
ZServer, check out the zope_handler.py, it has options to set the
SCRIPT_NAME. ZopeHTTPServer also has options to set the SCRIPT_NAME with
command line arguments.

Right.

>to be clearer.

Perhaps the docs should be updated. The manager's guide probably assumes
that you're using PCGI, but it shouldn't make this assumption.

Hope this helps.

Message-ID: <Pine.LNX.3.96.990309162504.454A-100000@taos.kavi.com>

Is this behaviour a bug?

I have all my ZSQL methods collected together in a folder. If I call these
from a sibling folder[1] without any arguments, ie.

<!--#in "sql.company"-->

I get the below error, if I call them with specific arguments, ie.

<!--#in "sql.company(comp_id=_['comp_id'])"-->

I get no errors. (comp_id was in REQUEST in both cases).

[1] by sibling folder I mean something like the following arrangement...

/sql/company  		(where the sql method is stored)
/lists/company_list 	(where the call is made)

Here's the error:

<!--
 Error type:  
 Error value: 0

Looking into it, line 332 in Aqueduct.py is a simple key lookup...

    def __getitem__(self, key): return self._data[key]

It would seem that an argument is getting passed in by default when the
sql in put in a parent's subfolder.

Message-ID: <Pine.LNX.3.95.990309165933.6532A-100000@animal.blarg.net>

I have been playing around with Zope/ZPublisher/DocumentTemplate and have
been extremely pleased with the ease of development, as well as the power
of the Python language.

Sometimes I have found myself wanting to save the results of an expression
in my DTML code, for use later in the same page (or even an embedded DTML
object).  The only thing I have used that is similar to DTML is
ColdFusion, which has a CFSET tag, ie: <cfset myvar = "test"> or
<cfset total = subtotal * tax>

In reading the docs, it looked like I might be able to do something along
the lines of <!--#call "REQUEST.set('var', 'value')--> but this didn't
seem to work, and it's not very elegant either.

Am I missing something? None of the howtos or tutorials seem to cover
this.  A <!--#set newvar=oldvar--> / <!--#set var="expr"--> would be
really spiffy. =)

Please make sure you CC me if you respond to this message, as I had to
unsubscribe due to the overwhelming amount of traffic.

Thanks!

Subject: [Zope] tree doesn't work 4me linux amd win32

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?



I had the same problem, but only with Zope 1.10.2.  I noticed that DTML
documents (the default to be created) won't work with the tree tag.  If you
create a DTML Method (like the old DTML from Zope 1.9) then they work as
expected.  I don't have a clue as to why this works like this.  Maybe its
the proerties of the DTML Documents that are acting folderish and tree
doesn't know what to do?

Hope that helps,

Message-ID: <4.1.19990309224955.009de8f0@10.0.0.1>

We have been unable to access properties of the new DTML Document objects
in the same way we used to access properties of Folders. 

I don't know whether we are doing something wrong or we found an
inconsistency in the new 1.10 Zope API.

Here is a very simplified test case illustrating the issue.

I have a folder with these contents:

folder1 [Folder]
- broken_html [DTML Document]
- index_html [DTML Document]
- sub-document (The Grand Sub-Document) [DTML Document]
- sub-folder (The Grand Sub-Folder) [Folder]

The source of index_html (which works) is:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-folder'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-folder'].author"--></p>
<!--#var standard_html_footer-->

This works as expected. The properties title and author of the sub-folder
are retrieved.

The source of broken_html is exactly the same, except for the sub-document
reference:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-document'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-document'].author"--></p>
<!--#var standard_html_footer-->

Viewing this document-method I get a "Zope Unavailable" message with this
traceback:

<!--
 Error type:  
 Error value: 'string' object has no attribute 'title'
 -->
</BODY></HTML>
<!--

So, how do I access properties of sub-documents from a sub-document in the

One way is to use DTML Methods instead of DTML Documents.

Nope, ZHS (for short) is derived from the example CGIHTTPServer.py that
ships with Python---it's heavily modified though.  ZServer is what is
derived from Medusa and is currently in alpha (though pretty stable for
me).

As for SSL, not currently, and I'm not sure what's going to happen with
this.  You can use Apache+SSL right now for this.  I've had some
thoughts about it, but I'm not sure how SSL will impact an async-socket
based system...  the setup of new SSL connections is kind of heavy.

I am using:
Red Hat 5.2
Zope 1.10.2

- I created a username of "zope_u" and a group "zope"

- I did run the installation script with a command line like:
        ./install -sAdmin:MyPassword -u zope_u -g zope

- I created the Feedback and SendFeedback forms as per the manuals.

- I added the user "zope_u" to the mail group.

- I modified user zope_u's .bash_profile file to include the path to
sendmail in /usr/sbin

- If I log-in to the Linux server as zope_u, I _am_ able to call sendmail
and to send mail outside of the server.

Anything else I missed, folks?

Regards.

I understand the difference between DTML Methods and DTML Documents. 

The very reason I chose to do it with DTML Documents was to be able to
store some special fields, such as 'author' in my example, along with the
document. I cannot do that with DTML Methods, as they do not have properties.

In Zope 1.0.9 I used folders but I was running into problems with relative
links. It seemed natural to switch from my previous folders to the new DTML
Documents.

I still do not know to reference the properties of a DTML Document 'A' from
within a document or method 'B' in located in the same folder as 'A'.

Thanks for any help.

You are right. I was using folders too for the same reason.

You can use the PARENTS variable.

so if you have a folder which contains two DTML Documents A and B then
you can access B's properties from A by:
<!--# var "PARENTS[0].B.name"-->
PARENTS[1] will return the folder or containing object one level up and 
PARENTS[-1] will return the top most Folder.

Thanks for your help, Pavlos. I found another way. Instead of writing:

<!--#var expr="_['sub-document'].author"-->

I wrote this, and it worked fine:

<!--#var expr="_.getitem('sub-document').author"-->

I found a way, but I don't understand why the first syntax worked fine with
Folders and fails with DTML Documents. If anyone would like to clarify the
semantic difference between _['sub-document'] and
_.getitem('sub-document'), I would be even happier.

By the way, Pavlo's site http://www.gaaros.com:9673/ is useful!

The answer is in both the ZDP's FAQ and the DTML Manager's Guide. 

_['foo'] "renders" foo according to DTML rules. This process mostly
consists of calling DTML and other callable objects.

_.getitem('foo') simply returns foo as found in the DTML namespace.

The reason you were having problems is that _['sub-document'] renders the
document to a string. Naturally strings don't have properties. Hence the
error you got from Zope, "'string' object has no attribute 'title'".

Make sense?

Subject: [Zope] Another "no such file" failure...
Message-ID: <Pine.BSF.4.05.9903092345060.330-100000@guru.phone.net>

I'm trying to get zope working to study it, but keep stumbling over
the "(102) failure during connect" error - with the "No such file or
directory" addendum.

The underlying OS is FreeBSD 3.1. I want to run it on an Apache web
server (at least for now), with the server doing the
authentication. That all appears to be working properly - after all,
I'm getting errors from pcgi, now, right?

The var directory is writable by nobody. In fact, the entire source
tree is owned by nobody, which is the user that the Apache httpd is
running as. However, I get log file entries from pcgi, even after
deleting the pcgi.log file. I initially tried copying the Zope.cgi
file to cgi-bin, but noticed that some (unspecified) setting in
Zope.cgi might need to change because of that, so I added a second
scriptalias to the Apache httpd.conf pointing at the source directory,
set the protections on it, and tried to load <URL:
http://localhost/Zope-bin/Zope.cgi/manage >. No change - the log file
records the same error message.

The pcgifile.py test reports 

	error attempting: 'from cgi_module_publisher import publish_module'

This doesn't appear to exist in the distribution - and I recalled
something about that being a holdover from bobo, so I removed that
test from the script, and ran it again. The modified version runs
cleans.

Was I wrong about cgi_module_publisher? Should it be finding that? If
not, then what's the next thing to look at?

FWIW, here's the entry from httpd.conf section for Zope:

SriptAlias /Zope-bin/ "/home/mwm/external-src/Zope-1.10.2-src/"
<Directory "/home/mwm/external-src/Zope-1.10.2-src/">
	AllowOverride	None
	Options		None FollowSymLinks
	Auth_PGhost		sql
	Auth_PGport		5432
	Auth_PGdatabase		web
	Auth_PGpwd_table	users
	Auth_PGuid_field	name
	Auth_PGpwd_field	password
	Auth_PG_encrypted	off

	AuthName		"Zope"
	AuthType 		basic
	require			valid-user
</Directory>

And here's Zope.cgi:

   You don't need hostname and port part, so the connection string can be
just "baseball user_name".
   (BTW, without host:port, libpq will connect to postgres using UNIX
sockets, not TCP/IP. I think it is much better - for speed and security)

I've got an external method that is generating a (possibly quite large) 
audio file and sending it back. Right now, I'm generating this in memory
in a big string, then returning it to zope. I'd _like_ to be able to just
have the external method send the data straight through (maybe in chunks)
without having to read it all into memory. Is this possible with zope
at all?

Because you are calling "sql.company" (in quotes), it is assumed to be an
expression, and your expression is referencing an attribute, not a method.
Try using the following: "sql.company()", or sql.company (without quotes).
Note: I didn't test either method.

MailHost doesn't use sendmail, but rather opens a socket to the specified
sendmail host and uses the SMTP protocol to send the messages. This is
somehow prohibited. It looks like there is maybe no SMTP server listening
on the specified address and port, or your machine is not allowed to
connect. You could try and do a manual telnet to the address and port from
the zope_u account and see what happens.

Make sure you also go through the motions, like HELO <hostname>, and such.

Can #sqltest handle the 'wildcard' situation in MySQL (and probably 
other DBMSs too)

select * from tbl where tbl_val like '%nib%' is a different SQL query from
select * from tbl where tbl_val = 'niblet'

my attempt...

I think the first problem will be finding a publisher that streams.
PCGI buffers all I/O, perhaps FastCGI doesn't.  Even if you didn't,
sending it through Zope in chunks would avoid getting Zope's memory
footprint up there.

One way would be to have the ExternalMethod return a sequence, then do
something like:

<!--#in myExtMeth-->
  <!--#var "RESPONSE.write(sequence_item)"-->
<!--#/in-->

Of course the above might be completely wrong, but you get the drift :^)

Hi all,

I'm using some image buttons and am having trouble getting the return =
values for them.

I have a button called answerbtn and the return values would be =
'answerbtn.x' and 'answerbtn.y', I need to check one of these values to =
check whether this button was pressed.

I have tried _['answerbtn.x'] but I get a traceback from Zope.

Any Ideas?

TIA

Yes, it's a holdover from Bobo days (which some people are
still using for existing apps) but you can ignore that
particular error.

Contact me offline and we'll try to get this resolved.

Try::

   <PRE><!--#var REQUEST.form--></PRE>

or::

   <!--#in "REQUEST.form.items()"-->
      <LI><!--#var sequence-key-->: <!--#var sequence-item-->
   <!--#else-->
      No form items
   <!--#/in-->

To generate an overview of all form variables your DTML has access to.

Thanks for the suggestion Martijn but I've already tried that and it does
indeed show variables of the form 'answerbtn.x'.  But when I try to access
them using one of:

<!--#var answerbtn.x--> or
<!--#var _['answerbtn.x']--> or
<!--#var _.getitem('answerbtn.x')-->

I get a traceback error, so I am none the wiser 8^(

Thanks anyway

Any other ideas?

Nope.  ZopeHTTPServer is not Medusa, it is based on the HTTPServer that
comes with Python.  Medusa is it's own product, that we have integrated
parts of into ZServer (which uses the core of Medusa to drive it's
network end).

http://www.nightmare.com/medusa/

For medusa info.  http://www.zope.org/ for info on ZServer.

Once ZServer is stable (it is alpha at the moment) use of ZopeHTTPServer
will be depreciated (but not forgotten).

Message-ID: <199903101525.KAA25149@mail.howard.k12.md.us>

Having seen Zope recommended on Usenet last week, I decided to check it 
out, Monday I found the Webreview article in the email box.  I have been 
reading as much as I can find, but one question is always on my mind, 
when ever I find one of these wonderful, does it all systems.

Can I install it ?  Not, is it to complicated to install, but do I need 
root access to the machine to install this application.  This question 
and the answer have killed many a promising application (DB & BBS).

So, the question is, can Zope be installed in a typical Telnet account ?

The install docs mention, you have to be root user, to install some 
components, does this mean what I fear it means ? (machine admin, ie. 
super user)

Yes.  I am trying to reference a folder that is not in the same path.
And I tried your next suggestion a long time ago, with no luck. 
<!--#var candidate1.name-->, and get an error with traceback:

<!--

This doesn't work.  My paths are like, /staff/candidates/candidate1, and
staff/companies/company1/job1/submission1/MyDocument.  I am trying to
reference a property of the candidate1 folder in the MyDocument
document.

Hmm,

More on the image button saga.

It seem's that <!--#var answerbtn.x--> does indeed work, but <!--#var
_['answerbtn.x']--> doesn't, and neither does the getitem way.

Seems weird to me, any ideas?

TIA

You should be able to install a binary package as a typical user on a
UNIX machine.  If your machine already has Python 1.5.1 or higher
installed (don't they all?!?!?! :-) then you can just install the basic
source distribution of Zope and do the:

	$ python wo_pcgi.py

Thing :-)  You can then use the ZopeHTTPServer on a untrusted port (over
1000) and off you go :-)  If you want to use Apache+PCGI you probably
will need administrator support, and if yo uwant to be on a port under
1000 you'll need it.

You should be able to get a feel for it without being root.

Try Zap, the precompiled apache for Zope (Linux only).  The zap.conf
file will probably have something your not including in your apache.
also, do an 'httpd -l' and make sure you have mod_rewrite compiled
and/or dynamicly loaded in.

candidates is the object that is the common ancestor, and from there you
can reference objects down that path. You will have to place the expression
into quotes, however.

You can indeed install it. I had originally had a standard telnet 
sort of account on a FreeBSD machine. You can basically get a 
full-featured Zope if your web provider runs apache with mod_rewrite.
(If they don't have mod_rewrite, authentication is a little bit more
of a headache.)

The thing to beware of is that PCGI starts a long running process
and many hosting companies will not be pleased about this.

Zope 1.10.2

I have a ZSQL method for inserting data into the database.
The database connection is active.
the permissions are correct.
the method is defined roughly as:

insert into tblname (col1, col3, col4, col5) values
(col1val, "value taht is constant", col4val, col5val);

when I try and test it, Zope tells me that there
is a parse error near ';'.

I remove teh ';' and Zope tells me that 
"This was not a query."

I'm missing something, and I'm hoping it's not my 
mind . . . any help?

(oh, nad yes, the query works just fine when entered
by hand in a mysql or xmysql connection)

Subject: [Zope] title and id properties in DTML methods
Message-ID: <36E6A70C.687B26BA@pop.vet.uu.nl>

Hi everybody,

I'm probably completely confused, but if I understood it right, DTML
Methods in Zope 1.10 are the same as Documents in Zope 1.9. I may
remember wrongly, but wasn't it so that

<!--#var title_or_id-->
<!--#var title-->
<!--#var title-->

in 1.9 documents rendered the title and id of the actual document, and
not that of the containing folder? In 1.10 in DTML methods, they appear
to render the containing folder, instead. The only way I can access
title of a DTML method in 1.10, is by referring to it specifically, i.e.
<!--#var "some_method_id.title"-->.

It works as expected with DTML Documents.

Is this as it should be? Am I correct about the 1.9 behavior? If so,
then DTML Methods don't seem to be exactly equivalent to 1.9 Documents,
and this should probably be in the FAQ. :)

Regards,

Martijn

Do it without the ';'. When it says 'that was not a query' it simply
means that there was no returned results for it to display. If you check
the database, the values should have been successfully inserted.

If you're doing just a single query, you don't need the ';' (or its
equivilent).

If you're doing multiple queries, use <!--#var sql_delimiter--> to seperate
them.  The DA will seperate the queries using this.  This is equivilent to
what command line or other SQL tools often do with the ';' character.

> I remove teh ';' and Zope tells me that
> "This was not a query."

Nothing is being returned is what this means (or more basically, it wasn't
a SELECT based query).

I can't use another apache just for Zope. I looked into zap.conf and
incorporated some changes into my httpd.conf. No way.

Since the log file of RewriteLog remains empty, I believe no rewriting
takes place, actually. I have about 30 virtual servers on that httpd,
maybe there lies the problem? Also this is Apache 1.3.3, do I need
Apache 1.3.4?

hi!

No. Zope works fine with Apache 1.3.3. Did you remember to set the ExecCGI
option? And did you remember to turn the RewriteEngine on?

Yes I turned rewite engine on, but maybe not in the right place. I wrote
it into global config.

I believe do not need to use ExecCGI, since I use ScriptAlias. And
Zope.cgi gets executed, I otherwise wouldn't be able to get to Zope
introductory. 

I'm desperate....

Something in an external method similar to this should do the job.

from string import split, join

def stringtounderscore(str):
	return join(split(str," "),"_");

which is then called from your page as 
<!--#var "stringtounderscore(mystring)"-->

Alternatively, if this is something you only need occasionally, you can
code it directly in DTML...

<!--#var "_.string.join(_.string.split(mystring,' '),'_'"-->

Both of these are untested, but I have tested the join/split command in
python directly:

>>> join(split("this is a test string"," "),"_")
'this_is_a_test_string'
>>>

You can use something like:

<!--# var "_.getitem('foo',0).whateverproperty"--> (Is 0 the default?)

_.getitem('foo',0) returns a reference to the object with id foo.

Hello!

   In ExternalMethods.html I found: "ernal Methods operate just like normal

Scripts. Are there other? Could I put Python code into Object Database?
Should I?

Thanks for a very fast reply, however it doesn't work. I'm still getting:
Error value: 'string' object has no attribute 'title'.

This is what I'm trying to do:
A DTML document (index_html) has a property art1 which has an ID for another
DTML document as value (type: string). In index_html I use: <!--#var
"_[_[('art1')]]"--> which renders the article. I can of course use
<!--#var title--> in the actual article, but I rather don't. So I'm still
banging my head in the wall after hours of trying to accomplish this. Can it
be a bug with DTML documents??

Best regards Wiebe Kunst

I think that DTML Methods (or Documents?) are meant. They are like
methods to the folder objects that Zope publishes. Look at:
http://localhost/Zope/foo/bar/doc as asking Zope 'okay, folder 'foo', I
want your subfolder 'bar' (this could be seen as using a method on foo
to request 'bar'), and then I want to view 'doc' (which is, let's say, a
DTML method) in bar. 'doc' in that case is a method of the bar object,
which, when called, returns HTML code (to the browser).

An *external* method is a method which comes from outside the Zope
object database (though it's loaded into it, and behaves just like a
normal internal method).

If all this talk turns out to be correct (somebody tell me or send
corrections), then I can turn this into a FAQ entry. If anybody else
feels like writing this up in a nice way for the FAQ (Oleg?) that'd even
be better. Just send your contributions to the ZDP list.

Hi!

   That is, there are DTML Scripts and External Methods. Python code is
used in External Methods and Products, but never goes into Object Database.

I think it's true Product python code doesn't go into the Object
Database, but I'm unclear about what happens with External Method python
code. You need press the 'edit' button for an external method in Zope
each time you changed something in it and want it updated. This would
imply Python code can indeed be part of the Object database, right?

I can confirm this; this one bit me too, I recall. Can anyone write up a

FAQ document on Apache with Zope too, what's the status on this?).

Actually not. For security reasons the code of an External method does
not reside in the Object Database but in the filesystem. When you press
the 'edit' button the code is read and evaluated and it is the evaluated
code that is stored in the Object Database. There was a thread about
whether the source code should be included in the Object Database but I
think thge Digital Creators were not convinced.

I have a form here wich should submit 5 values on to an external python

function is no problem - more then one is. Questions arise....
How are more than 1 value submitted from a form? How can I get those values 
passed onto an external method, and have the values assigned to the functions 
argument?

Help is much appreciated!

No, it forces Python to recompile the code. The code itself is NOT stored
int the object database. Only instance data is stored in the object
database, no code is. Zope classes are said to change all this, aren't
they, DC?

Pressing the 'edit' button "reloads" that particular External Method code
into the system.  It's not stored in the database at all - the External
Method object you add/edit through the Zope management screens is primarily
a pointer/wrapper to a method in a module in the Extensions directory.  The
Edit button in essence acts similar to the reload(module) function in
Python.

Basically, Zope (and Python) don't have a way of knowing the code in a
module has changed unless it's explicitly reloaded, which is a good thing.

Well this is how I understood the process.

Basically the code is read and exec-ed and the the func_code
func_code.co_varnames are extracted. Then they apply all the clever tricks
to turn the function into a valid Zope method, by (I assume) creating a
Zope method and replacing its func_code and the associated func_defaults
and arguments with the ones extracted from the external function.

The relevant code can be found in
Zope/lib/python/App/Extensions.py and
Zope/lib/python/Products/ExternalMethod/ExternalMethod.py

External Methods are (to the best of my knowledge) evaluated and their
compiled code is kept in process memory (effectively cached) the first time
the object (the External Method object pointing to a particular
module/method) is activated.  It is removed from process memory when the
object is de-activated.

This is kindof a tricky process and may be effectively cleaned up in the
near future so I won't go into too many details here.  An important thing
to keep in mind is (again, this may change soon) that the compiled code is
kept locally in each External Method Object.  If you have two EM's in Zope
pointing to the same code, you have to use the "Edit" button on _both_
External Method objects to effectively reload it.

Message-ID: <19990311184413.A1175@RaVER.duck.org>

Hi!

Just made a small test-site, and followed the Zope magager guide to how to
let anyone view my newly made site, but thisg doesn't work. The doc say that
by default everyone should have access to view the contents of a site made
by zope, but here the authorization/authentication dialogue pops up whenever
someone try to access the site. Cancelling username/passwd just ends in
failure. Why ? I'm using apache as webserver for zope and has made it so that
apache handles the authentication bit, but still - shouldn't it let
'anonymous' trough? I've had a look at the security settings for both
folders and files and they all let 'anonymous view'. Whats wrong?

When you say that you made it so that Apache handles the authentication,
I take that to mean you have created a .htaccess file? If that is the
case, Apache will always prompt for the password and check it against
your password file. If you use mod_rewrite to let Zope handle authentication,
you will not see the password prompt for resources that are available
to anonymous users.

The guestbook product is broken in 1.10.2. I've 'fixed' it by removing
both references to OFS.DocumentHandler (import and class inheritance).  
Now it's not broken, but it doesn't seem to work! Anytime I enter any

Has anyone fixed this?

BTW, I couldn't find an author name listed anywhere.

Hello Zopesters:

Are you confused by the subtleties of DTML? Want the skinny on advanced
DTML tricks and gotchas? Check out my advanced DTML HowTo:

http://www.zope.org/Documentation/HowTo/DTML

This document explains in detail the concepts behind advanced DTML tricks
like indirect variable lookup, setting variables, calling sub-templates
with different client objects, etc. Its main emphasis is on understanding
how DTML uses a namespace stack to manage variable lookups.

Enjoy and send me your feedback.

-Amos

P.S. Probably at least some of this material will be incorporated into the
DTML User's Guide in the future.

Thanks! Although by now I knew most of what was mentioned (though it

Excelent! This is so much clearer than isolated answers to 'how-do-I'

Message-ID: <Pine.LNX.4.04.9903111551260.32022-100000@dolemite.psionic.com>

Hello,

I've looked through all the docs, FAQs and threads of the Zope list for
some of these answers and haven't found a clear method described. I'll
apologize now if the questions seem obvious, but I'm new to deploying Zope
on a web server and need some initial Zope setup guidance.


Question 1: 

Under Zope, what is the proper way to configure the website so users can
simply go to http://www.example.com instead of:

http://www.example.com/example
http://www.example.com:9673/
etc.

My understanding is that the mod_rewrite rules will have to come into
effect here. Will I also need to do a re-direct of some type? I need
some way to direct all URL requests so they are re-written to point to the
correct Zope folder. The ideal for me is to have a series of folders in
Zope that contain separate websites. The sites can be virtual hosted as
needed (although right now I'm only running one site). I can't find a
clear description of how to make this happen. Also I don't want to run a
separate Zope process and proxy people to the port. I want to have
everything running on port 80.

I'll have to agree with other posters that a tutorial on the design of
the actual Zope site with Zope would be very helpful as they are using a
layout of html and hierarchy that is very similar to what I'm pursuing. In
fact if someone could provide me with a description of the config they're
using it would be a huge help.


Question 2:

Under .DTML construction of links is it generally considered "better"
Zope practice to reference the entire URL or the Zope object hierarchy
directly?

Question 3: 

I don't want tracebacks to appear under any circumstances to the end
users. I haven't tried anything to counter this yet, but wanted to know
what some others have done. Would an approach to this be a try/except
positioned in the standard_html_header and footer files? Ideally I would
like to catch all exceptions and have it automatically mail the exceptions
to the webmaster instead of showing the user (In fact I think this would
be a good feature for the product). 

Question 4:

Has anyone pursued a security audit of the Zope code? I've been
considering doing this (not that I don't trust the Zope developers,
it's just that I don't trust anyone) and would like to work with
others if possible. Several of the sites I admin get hacked on very
frequently and I'm a little nervous about replacing static web pages with
no CGI running anywhere with the exact opposite end of the spectrum with
Zope. :) 

I'm also going to prepare a document describing how to run Zope
in a chroot() environment under UNIX to increase security. I'll let the
list know when it is complete.

Thank you for any responses,

-- Craig

I'm new to this list.

It seems to me that the www.zope.org is rather slow this week.  Documents
are taking far too long to be parsed.  Pings seem reasonable, so I am
expecting that the server may be receiving a lot of requests and being
overloaded (maybe from the Web Review article).  So I am just wondering what
the specs of the system that the www.zope.org ISP is using.  Also wondering
about stress tests and benchmarks for the Zope system.  (It must also depend
on backend systems etc)

Hi,

	Using Zope 1.10.2 on Win95, I was trying to set permissions on
a DTML Method. I was trying to set everything except "View" to the
Acquired permissions. View was turned on only for "Manager" and "Editor".
When I click the change button after setting things as I just described,
I get the following Traceback:

If I'm not doing something foolish here, I'll submit this to the Collector.

Use Apache's VirtualHost ability...
Look here for more info: http://www.apache.org/docs/vhosts/
An example:

# in httpd.conf

# your ip
NameVirtualHost 192.123.44.3

# your standard host.domain (this must come first)
<VirtualHost 192.123.44.3>
ServerName your.standard.name
DocumentRoot /home/httpd/html
</VirtualHost>

# one or more extra virtual hosts
<VirtualHost 192.123.44.3>
ServerName your.zope.name
DocumentRoot /home/httpd/html
RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 \
	[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

I'm the guilty party (!)

I found this problem before but so far haven't found the fix.... here's what
I originally posted to the list.

I'd like to get this sorted out as I'm also working on a Souped (Zoped?) up
version of Amos's poll product, which produces pie-chart gifs in response to
the poll results, but it also broke in much the same manner going from 1.9
to 1.10. So any help on this matter would be much appreciated!

Cheers,

Andy.

Subject: RE: [Zope] Guestbook Product


I get the same thing :(

Hmm.. looks like DocumentHandler no longer exists.

I've taken out DocumentHandler from the Guestbook, to mimick the change that
has been made to 'Folder' going from 1.9->1.10. When doing the guestbook, I
kept making sideways glances to Folder.py to see how it was done ;)

The book no longer crashes but I'm getting some other wierdness. The
guestbook is a folderish product which contains two documents that the user
can add to change the appearance of the guestbook. They're added by the
following lines in the 'add' method ...

        # Add a Document used to view previous entries
        fileName = os.path.join(prefix,'index.dtml')
        index2 = open(fileName,'r').read()
        i = DTMLMethod(index2,__name__='index_html')
        print "i is %s" % i.meta_type
        i.title='Change me to determine how entries are viewed'
        self._setObject('index_html',i)
        print "ObjectItems is %s" % list(self.objectItems())

The added objects no longer seem to be showing up in objectItems().

The debug statement, when run on 1.9 prints out the newly added object in
the call to 'objectItems()', while on 1.10 it returns an empty list. Is this
a side-effect of the removal of DocumentHandler? I thought that _setObject
was being inherited from ObjectManager, so wouldn't be affected by the
removal of DocumentHandler.

Cheers,

Andy.

Well, under RedHat 5.2, mod_rewrite is a DSO, and is activated
in the *middle* of the httpd.conf.
I had the same problem. The rewrite rules put a the top of the file
have no effect because they occur *before* mod_rewrite is activated.

I had to put the rewrite rules a the end of the file.
I works now.

I don't know if this will solve your problem, but, just in case...

Subject: [Zope] access content informations & use mailhost services properties
Message-ID: <00a401be6c5d$caec6180$147800a0@pc-pi0>

Hello,

Correct me if i'm wrong: one has got to have "access content informations"
permission to be able to write:

<!--#with Folder--><!--#var title_or_id--><!--#/with-->

right? I've been bitten with that, and once i gave "access content
informations"
to the Anonymous User, my problem went away.

Also, before I submit this to the Collector, is it normal that the "use
mailhost services"
doesn't appear in the security tab of the folders? Each product has its
permissions
that are listed, but nothing with the mailhost object.
I had to change it directly in the mailhost object.
If it's normal, it means that i can't give global permission for mailhost
objects???
What confuse me, however, is that the mailhost object claims to "acquire"
permission
settings from its parents, but nowhere in its parents i can define the
permissions.

Hi all ,

We try to use DocumentTemplate not for HTML dynamic generation but for
C++ generation. For convenience, and because we are familiar with Python
we intend to use the Alternate Python String Format Syntax. The
generation code is beautiful compared to our previous output.write("blah
blah.... ") instructions.

Reading the docs, looking at the Zope site, this behaviour doesn't seem
to be shared by a lot of zope users. Moreover the Alternate Python
String Format Syntax  is poorly documented, and DTML features seems to
be usable but the way they can be used seem very strange. Basically our
needs are to use conditional structures, iterative structures and to
call methods. The last point seems to be the hardest one. The following
code shows a way to call python methods in python strings but 3 persons
during half a day have been necessary to find it out.

I suppose you can imagine my questions :

Is there a natural and convenient way to find out PSFS expressions going
from their DTML equivalent  ?
Is there a complete documentation on PSFS syntax ?
Are the features of DTML and PSFS identical ?
And the most important :
Do you encourage us to keep on using PSFS instead of DTML ?

Thank for your help
Stephane

Well you were both right. I have turned on ExecCGI for my standard
cgi-bin directory, where I placed a copy of Zope.cgi. It is NOT
neccessary to add <Directory> statement for /usr/local/zope/ (I thought
it was neccessary... so I'm writing it here for the upcoming FAQ). Also
I thought that I should use http://www.domain.com/cgi-bin/Zope.cgi
address, which brings the introductory screen (that fooled me) but does
not allow authorization. The correct address is of course
http://www.domain.com/Zope, since that's what the rewrite rule is about. 

Thanks to all who helped me!

Hi Ron.  Just a guess, but how about having the tree tag pass in the the
current level as an argument to the same SQL method, then have the SQL
method adapt itself based on the argument?  Remember that an SQL method
can embed logic and act like an object using DTML.  For instance:

<!--#if "level==1"-->
  select ...
<!--#elif "level==2"-->
  select ...
etc.

The installer for the Zope NT binary asks you if you want to run as a
service -- in fact, that's the default.  Take a look at the file
"doc/INSTALL.txt", under Installation on Windows, for more information.

I'm not sure if the Zope universe is big enough yet for that.  I rememer
Guido doing this for Python about a year ago and nobody showed up. :^)

Perhaps if there were coordinated events?

I think the answer will certainly be yes.  Go to:

I do hope there is. If implemented like the Apache JServ module
(http://java.apache.org/) it should solve a lot of problems for everyone,
adding performance to boot.

JServ is in effect a separate process (like Zope) that receives it's
request via the Apache server, with the help of a module, that translates
the requests into socket calls.

If someone modifies the module that comes with JServ to call the Zope
process instead of the JServ process.....

I've moved slashdot.py into Extensions and set up an external method 
(id: get_headlines, funstion name: get_headlines, python module: 
slashdot).

My 'calling' DTML is a method (slashdot_headlines) with the following;
<!--#call get_headlines-->        
<!--#in headlines mapping-->
<p>
<a href="<!--#var href-->"><!--#var title--></a>

trying 'view' on this method gives the following;

I *did* have a problem with using a proxy, but got around that by 
adding this line to slashdot.py (just before the urllib.urlopen() 
call).
urllib.URLopener(proxies={'http': 'http://cache-box.you.domain:your_port'})

What am I doing wrong?

A mod_pcgi Apache module has been discussed.  It would certainly
be more efficient.  One of the issues would be whether pcgi
should get out of the process launch business, which would
simplify a mod_pcgi and make it easier to debug.

Ok, I'll check that out.  My experience has been than I run it with
start.bat and when I close that ms-dos window zope stops.

I think that now that zope is "out there " and is open source that you will

If your external method is called from DTML document 'foo' then something
like this should do it (untested):

def mymethod(self):
	if not self.hasProperty('myproperty'):
		self.manage_addProperty('myproperty','hello','string')

BTW you can achieve the same effect from DTML

<!--# unless myproperty-->
<!--# call "manage_addProperty('myproperty','hello','string')"-->
<!--#/unless-->

This is a buglet in ExternalMethod where an exception has been raised and
caught by ExternalMethod, and EM is looking at the values of the traceback
for some special conditions.  It's trying to do a string.lower() call on
one of the values that in Python1.4 was always a string, but in Python1.5.x
is an instance (in Python 1.5, standard exceptions became classes).  This
has been fixed and will be in the next release.

Welcome to the list Andrew! I'm glad you found my suggestions
interesting enough to check Zope out. Regarding my last email, did you
figure out how to do PUT and GET from DW yet? And do you know if
Macromedia is going to add WebDAV support to DW?

In case you missed it, I'd like to point you towards the Advanced DTML
Howto:
http://www.zope.org/Documentation/HowTo/DTML
as that has more thorough information than the DTML guide I showed you
before.

I would also be interested in a newsgroup, as I am currently filtering
the email into a folder and sorting it by thread, but a newsgroup would
let me see the the same threaded view from home, as well. This would
also have the effect of letting new users see the context of the current
posts.

Subject: [Zope] Access Control Advice
Message-ID: <Pine.LNX.3.96.990312123932.13260A-100000@taos.kavi.com>

Hello all,

I am working on a Zope app, and would like to see if anyone has any tips
for how I should handle access control in this situation...

The site is a corporate organization site. It has many corporate members,
each has an admin which has control over a subset of information kept in a
relational database.

I want to have just one role (comp_admin) for this. But each company can
only have access to their company info. Thus I need to check that the
admin belongs to that company. (there are also regular users who also have
to login. they can view, but not modify)

The users, passwords and roles are kept in the database too (UserDB).

Each company has a unique id, and this is the primary keys in the DB. Each
user is associated to the company using this id (a field in their table). 

Make sense?

My current idea is:

1. Have a general main page which both users and admins login to. If they
use the admin login, get their company id (comp_id) and create a link to
the admin section using the magic of direct traversal (this way they can
bookmark the admin page). Eg.

<a href="/comp/1/admin/">admin section</a>
('comp' is the zsql method, 1 is the comp_id, admin is the folder)

Thus the comp_id of the company will be available, and I could:

A. I could then (mabey?) use the comp_id in the UserDB query (in the admin
   folder) to only retrieve those people belonging to that company.

OR (if I can't get to the comp_id from the UserDB query).

B. I could then compare to the person's comp_id to the company's comp_id 
   in each of the effect pages via a new standard_header.

Thoughts? Better ways to do this?

I haven't tryed this but on pg 10 of DTML Users Guide check out:

maketrans(FROM,TO)
and
translate(S,TABLE[, DELS])

it seems to do character for character translations.

Brian built a pretty cool way to hook SQL entries to particular
folder trees for the PDMS.  Each folder has a uniqueid which is
stored in a sql table, along with the folder parent heirarchy, when
an item is added to the SQL database.  This allows each folder to
easily identify which SQL entries belong directly to it and which
SQL entries belong as children.  This allows one to easily do things
such as count the number of SQL items which are identified with a
folder tree using SQL query syntax.

Brian also provided dtml methods to move folders and their
relationships around in the Zope heirarchy quite nicely. The
mechanism holds quite a few SQL items in it and there has never
been a need for a Python or SQL god to do any maintenance on the
system at that level.

However, it does use both SQL and External Methods. So, don't
believe that just because something requires a fairly deep level
of competence to create that it requires that same level of competence
to maintain (me for example :^).  That's simply one mark of a decent
implementation.

Message-ID: <9903121826.ZM7584@saab.coinet.com>

This may be a newbie question, but I've loked thru the doc and didn't
spot any obvious way to do this, short of an External Method.

What I want to do is given a limit number, iterate over a sequence of
DTML commands. This would be an obvious use for #in (which I'm using
elsewhere for other things) except I don't have a sequence - just the
number of items in the sequence, as it were.

In psuedo-code, what I'm after is something like this:
	for (i=0; i < <!--#var max_items-->; i++)
	{
	  // some DTML/HTML code using "i"
	}

Now if, given a #var, I could get a list - e.g.:
	<!--#var max_items--> --> list = [0, 1, 2, ... max_items]
or [1, 2, ... max_items], it doesn't make much difference.
then I could just use:
	<!--#in list-->
	// some stuff using <!--#var sequence-index-->
	<!--#/in-->

Is there an easy way to do this? Is there *any* way to do it?

Subject: [Zope] User Profiles?
Message-ID: <Pine.LNX.4.04.9903122303421.21162-100000@zeus.carolina.rr.com>

I am working on a web site for a local outdoors group. They have about
1,000 members and are growing fast, but their web site needs help. I had
lunch with their leader today, and strongly advocated the use of Zope to
redo their entire web site. He loved my ideas, and gave me the go ahead on
the site.

Now, my first question (I'm sure I'll have many) to the group is: How do I
create user profiles? Each user of the system needs to have specific
information associated with them including: full name, address, telephone
numbers, a picture (gif or jpeg, easily uploadable by the user), their
interests, a history of the events they've sponsored and/or attended, a
buddy list (basically just a collection of other member ids), and so on.

I have downloaded the UserDb product, and figure I might be able to extend
it to support the extra columns I require. However, a big part of me wants
to keep as much of this in Zope as I can. I like the idea of the
objectstore, and don't necessarily like having to fudge SQL tables every
time I add or remove an attribute from the profiles (not that I will be
doing that, necessarily).

What do those with a higher Zope Zen Rating than I suggest in this
situation? I'm also going to be making an Events Calendar, which is
connected up with all the User information (who's running the event, who's
signed up to attend, etc.). Is all of this something that Tabula would be
good for? If so, who do I have to sleep with to get it? :^) 

I am willing to write up a case study, testimonial, contribute any code I
write back to the community, etc., whatever is requested. I just want to
do a good job for these guys, making myself and Zope look good in the
process.

HELP! *grin*

I can see a  number of things that DW will (I think) do to  help out
Zope - but there is one item in the way - FTP support
There is no direct way for Dreamweaver to send pages back to Zope
without either writing to a filesystem via a LAN or by using FTP (no
webdav yet).

So my question is this - when will we get ftp support in zope? (not just
alpha).

I am looking at the dtml spec right now and thinking about building
drag-and-drop objects for DW that talk zope.
One thing I need is for someone on the zope team or elsewhere to help me
test these so that I get the syntax correct.

Recent notes about Lynx notwithstanding, I agree.  It's extremely
frustrating when debugging the security of an app!  Zope _CAN_ use a
cookie-based authentication scheme with the UserDB product.  UserDB uses
Database Adapter (e.g., Oracle) to connect to a store of user info
(e.g., userid and password).

I can imagine some motivated community member taking a look at the
current incarnation of UserFolder and UserDB and cookie-ifying the
UserFolder.

Since DTML already has at least two different syntaxes, would it 
be hard to give it another one, that used 'regular' tags? For getting-
user-acceptance purposes it would be really good to work with as 
many HTML editors as possible, even lame ones.

Having written the above, now I see that Jeffrey said it was a 
problem "with the current syntax" in his post.

Sorry if I'm raising a point that has been covered in a more 
intelligent way already. There are just so darn many messages on

As I understand it, Zope hands the data stream to PCGI who then, outside

Here's a brute-force way to do it, as long as the list of items was
short:

<!--#call "REQUEST.set('foo',['1',
                       '2','3','4','5'])"-->

That's fantastic!  Well there are lots of people on the list that are

I predict we'll have something like this called a Membership System,
say, May 18th for a first cut.

If my previous history of fibs, spinning, obfuscation, and downright
lies makes you suspicious, or if you distrust my poor prognostication,
I'd suggest that you take the user objects in UserFolder and turn them

There are many ways to do this, as you might imagine given
that Zope is a fully programmable environment. One such way
was done by Andy Smith (cc'ed on this reply) in building an
"alumni community site" for our (Andy and my) old
department. The site is http://www.ged.org. Unfortunately,
you won't be able to see much, as it's a password protected
site for members (there are two public pages). However, on
one of the public pages, you will note that it was the
intention all along to publish the source to the site for
the Zope Community at large.

As functional as the site is already, I think Andy had some
very cool extensions in mind before opening it up to the
public. Still, he can easily ship you the GEDUserFolder that
he built to keep track of everyone's contact info (easily
extendible to all of the fields you have in mind). As a user
of the site, I can assure you that it's a breeze to use!

Perhaps, this will also be incentive enough for Andy to
polish off some of his other goodies and release them :-)

Tablua, what's that? Just kidding, it's now called Z Tables
:-). For the moment, we are actively selling (without
actively promoting) Z Tables. While you get the source, it
is _not_ an Open Source product. The license does not permit
redistribution of any kind, and does not permit derivative
works, etc. It does, however, permit you to use it to
operate any kind of website, including a publicly accessible
one, etc... The price is dirt cheap for the functionality
(IMHO). The license also has a clause that specifically
permits Digital Creations to eventually release Z Tables as
Open Source(tm). Meaning, when we're ready to release it,
don't be mad that you paid for it when others get it for
free... This is important, because it is our intention that
over time, the vast majority of our stuff will be Open
Source!

So, why do we charge now? A few reasons:

1) The docs are really weak. Rather than get beat up in
   public for it, we have a license clause that forces you
   to acknowledge that the docs are weak, and that you need
   to be able to read source to really understand the full
   power.

2) Support. Everything that we put out there causes a
   certain amount of extra work. The more sophisticated the
   code, the more work. Z Tables is _hot_, so if it were out
   there in its current form, everyone would want to use it
   (trust me on this one!), so it would become a support
   burden for us. Pay us for the product, and it's worth our
   while to support you!

3) Before putting out something to the world, we really want
   to make sure it's been beat up. It may sound strange that
   we would charge people to help us turn something into a
   polished product, but it's already powerful enough to
   solve real problems, so motivated users are our best bet
   to help us achieve our goals for a more general release.

See some earlier posts from people who have recently gotten
Z Tables! For example, check out a recent
"performance-oriented" post by Theodore Patrick of
Indigo Networks!!!

Subject: [Zope] INSERT Syntax with Zope & ZPyGreSQLDA
Message-ID: <87hfrp1js9.fsf@eurythro.savigny.stp>

Hello,

I'm trying to use PostGreSQL with Zope, but I'm having
problems using the SQL INSERT method in Z methods which
require parameters.

For example, I make a Z SQL Method named 'foo'.
In it:
INSERT INTO messages
VALUES
  (<!--#sqlvar auteur type="string"-->, 
   'blahblahblah', 'now', 'f')

I write the name auteur in the 'arguments' form.

Next I create a DTML document with:
<form action="foo" method="GET">
Auteur: <input width="30" name="auteur" value=""><br>
<input type="submit" name="SUBMIT" value="Envoyer">
<form>

When submitting the form, it displays me a new page
(generated by Zope) asking me again the auteur parameter,
as if the auteur variable wasn't passed to the Z SQL method :-(

Someone posted a mail recently with an example use
of INSERT, where he put '(auteur)' after the 'INSERT INTO messages'
text: INSERT INTO messages (auteur) ...

When I try this, I get:

Error, pg.error: server fatal error. Please report to your db administrator. 

SQL used:

INSERT INTO messages (auteur)
VALUES
  ('testing again', 
   'blahblahblah', 'now', 'f')

Is there something specific to PostGreSQL ?
(Using Zope 1.10.2, PostGreSQL 6.4.2, PyGreSQL-2.2, ZPyGreSQLDA 0.02)

I looked in the Z SQL Method User's guide, but nothing is written
about adding data to a DB :-(

A good to test your SQL is using psql.

And upgrading to PyGreSQL 2.3 or later, which return proper sql messages

This is definitely wrong ;(

something like 
INSERT INTO messages (auteur,title,bookdate,any_good)
VALUES
  ('testing again',
   'blahblahblah', 'now', 'f')

might have worked. You may also mean current_date or current_time 
instead of now or now()

I didn't find any other way, either. But here's an External Method you can
use.

--- begin loop_range.py ---
LoopRangeError = 'LoopRangeError' # Name an exception class.
loop_range_limit = 100            # Maximum allowable loop index.

def loop_range(max):
    if max <= loop_range_limit:
	return range(max)
    else:
	raise LoopRangeError, max
--- end ---

Notice that it won't allow the "max" parameter to be bigger than 100. This
prevents users from generating near-infinite amounts of HTML and freezing
your server. You can edit this to any value you like, or even remove it if
you trust all your DTML authors.

Now, create an External method with the following properties:

  id:     loop_range
  title:  Loop Iteration Method
  method: loop_range
  file:   loop_range

To use this method in DTML, try the expr attribute of the #in construct:

--- begin sample DTML ---
<!--#in expr="loop_range(max=50)"-->
<P>Index: <!--#var sequence-item--></P>
<!--#/in-->
--- end ---

> Is there an easy way to do this? Is there *any* way to do it?

Yup. ;-) Zope has tons of power hiding under the hood, and a skilled Python
programmer could make it do almost anything.

Cheers,
Eric

One way of doing this would be using an external method:

def MyRange(iMax):
    return range(iMax)

The property bobobase_modification_time gives you the last modification
time. This is not in the docs, I gleaned it from Zope's source (it is used
in amongst other places the document edit screen). This is a good item for
the FAQ.

Message-ID: <Pine.LNX.4.04.9903132129250.14974-100000@zeus.carolina.rr.com>

Hello, everyone. I'm bustin' ass on my project for the outdoors group and
ran into a problem with the #sqlvar command.

At the top of the file, in the docstring, it says:

    For example, given the tag::

      <!--#sqlvar x type=nb optional>

    if the value of 'x' is::

      Let\'s do it

    then the text inserted is:

      'Let''s do it'

    however, if x is ommitted or an empty string, then the value
    inserted is 'null'.

Either I'm totally off base somewhere, or this is not correct. In one of
my SQL Methods I have a query, with a line:

  <!--#sqlvar address2 type=nb optional-->

And, when I submit the query while leaving address2 blank I get:

  Invalid empty string value for address2

When reading the code, beginning on line 200 there is the else case which
handles values of types other than int or float:

        else:
            v=str(v)
            if not v and t=='nb':
                raise ValueError, (
                    'Invalid empty string value for <em>%s</em>' % name)

            v=md.getitem('sql_quote__',0)(v)
            #if find(v,"\'") >= 0: v=join(split(v,"\'"),"''")
            #v="'%s'" % v

There is absolutely no check for the optional flag in this case as there
are in the cases for int and float. Is this check supposed to be handled
elsewhere in the code, and never make it here, or is this an oversight? I
can patch it to fix the problem quite easily, but if this is not the
preferred way of doing things I'd like to know (to avoid patching it every
time a new Zope comes out.)

I have two address lines, address1 and address2. I just want it to set
address2 to null if the user does not fill it out. Is that too much to
ask? :^)

As I said, if I'm blatantly overlooking something, please let me know. If
not, I'll be happy to submit a patch and/or report this in the collector.

Thanks. Hope you all are having a good weekend!

Hello all, 
First let me start by saying I've finally cleared time to play with zope.  
Its coming along nicely but I've hit a snag.  The following snippet in a 
form:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<!--#in qryListStaff -->
<OPTION VALUE="<!--#var user_id-->"><!--#var user_name-->
<!--#/in-->
</SELECT></TD></TR>

using MySQL produces the following HTML:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<OPTION VALUE="2L">Alan Johnston
<OPTION VALUE="1L">Tom Jenkins
</SELECT></TD></TR>

Now unfortunately I believe the L is causing the insert to fail with an 
invalid integer.  I specified user_id as integer unsigned zerofill 
auto_increment.  Does anyone know why the 'L' is being return?

TIA

The L value is caused by a long integer to string conversion. You can get
rid of the L by specifying a C format string, like so:

<!--#var user_id fmt="%u"-->

Ow you're right. But this hasn't changed anything, it still
ask me for the parameters after clicking on submit :-(

In the HTML form, I replaced the action with 
'<form action="add_message/manage_test" method="get">'

where add_message is the Z SQL method. And it adds correctly the
record to my Database, but displays 'This was not a query'.
And, well, I don't think taht's the correct method to add records,
by using the test method :-))

Is there anywhere an example of product adding some records to
a database ?

What's the difference between now and current_date / current_time
I tried all of them, and they give exactly the same result 
(the good date :-)

Message-ID: <199903141232.XAA17000@mbuna.arbhome.com.au>

Short Version of message: ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now 
available from http://www.interlink.com.au/anthony/python/

I'm looking for opinions on the LDAP zope product I've been building.

Right now, LDAP connections work, LDAP Methods work, but there's still 
a bit more to do. Right now, the following is unimplemented:

In ZLDAPconn:
. Anything other than simple_bind(who, passwd) for connecting to the 
    LDAP server
. meaningful doc strings

In ZLDAPMethods:
. Pluggable Brains
. Result Caching
. Limits on the number of results
. Variable interpolation in the filters, and in the base DN
. modify or add queries (only search is supported right now)
. meaningful doc strings :)

Other stuff:
. UserLDAP is not finished yet (or released) - the primary issue is the
    storing of roles and domains. Right now this would have to be some
    non-standard LDAP attribute... but what should it be? It also probably
    needs modify and add added to ZLDAPMethods before being really useful.

Things I'd like comments on:
For ZLDAPconn:
    what other bind methods would you like to see?
For ZLDAPMethods:
    how should add/modify/query be distinguished? Separate methods?

I had planned to get variable interpolation working tonight, but decided I'd
rather get an early night. Probably tomorrow evening, instead. Stuff I hope to
get going in the next day or so: variable interpolation, pluggable brains.

Anyway, ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from 
http://www.interlink.com.au/anthony/python/

It requires David Leonard's ldapmodule, from 
http://www.it.uq.edu.au/personal/leonard/dc-prj/ldapmodule/

It's been tested on Linux 2.2, under Zope 1.10.2 and ZServer. Assuming the
ldapmodule works on other platforms (it's available in source, and also as
a windows .pyd) it should work elsewhere, too.

Try something like:

<form action="add_message_result" method="get">

And then create a DTMLDocument or DTMLMethod called add_message_result
like this:

<!--#var standard_html_header-->

<!--#call "add_message(REQUEST)"-->

<h2>Success!</h2>

<p>
  Your message was added successfully! Thanks!
</p>

<!--#var standard_html_footer-->

The success message will only be shown if the query succeeds, because it
is below the #call statement.

Hope this helps!

The docs seem to imply that you provide fsdir with a *directory*
ie fsdir=/web/srvs-sol/www.so.cz/ppm

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC61@peter.sths.org>

How can I configure ZAP so that all http requests go through the cgi?
Zope is the only thing running through this apache, so I don't want
everything on the site prefixed with Zope/ (or anything else, so no, I
don't just want to know how to change the prefix). This is basically
what is keeping me on ZopeHTTPServer. 

BTW, running ZopeHTTPServer multi-threaded worked well for about 15
minutes. Then suddenly certain pages wouldn't load. I stopped and
restarted the server, but the pages still wouldn't load. I also noticed
that if I stopped Netscape and hit reload, it would cause several new
ZopeHTTPServer instances to appear, and doing so again would continue to
create new instances which never seemed to dissappear. Are these locking
the items they are downloading? The behavior I saw seemed consonant with
it locking the item it was downloading, then failing to recognize the
netscape had disconnected, and thus never removed its lock. When I
restarted it single-threaded, all the pages came up without a problem. I
would really like to move to Zap, but I can't afford at this point to
have the URL of the page change. 

How can I make a Zope pcgi accessible as the root of a Zap install?
Please help.

I've imported a directory using fsimport and it worked for me. I can only
suggest (clutching at straws here) that having '.' in the fsdir attribute
might be throwing it?

Even more clutching here - did you leave the trailing slash off the fsdir
attribute?

In lib/python/StructuredText/StructuredText.py, modify the ul() and ol() methods
as follows:

Change:

  if p: p="<p>%s</p>" % strip(ctag(p))

to

  if p: p="%s" % strip(ctag(p))

I posted a more robust diff to the zope-dev list last night, which allows

Subject: [Zope] Simulating static URLs, end-user session management
Message-ID: <36EC3A7B.53817A8D@erols.com>

Hi.  I am very new to Zope, having spent the last day
(with only about two hours of sleep) excitedly pouring through
the documentation.  I still have a lot to digest, but
there are some questions I did want to ask at this stage:

A)  Are there reasonable ways of arranging to have
    the URLs for some/many Zope generated pages appear, as
    far as the outside world is concerned, to be URLs
    for static HTML pages?  

    The issue is one of indexing by search engine robots.
    I anticipate building a site where most of the 
    content will change fairly slowly, and where there 
    would be a standard set of views of the data which 
    would be essentially static at a logical level.  I 
    really want search engines to index those static 
    views.  (There would likely also be dynamically
    generated views which shouldn't be indexed.)

    So, I think the requirement is that there should be a
    way of getting to pages with a URL like:

	http://www.mydomain.com/here/there/everywhere.html

    as opposed to

	http://www.mydomain.com/here/there/everywhere

    or

	http://www.mydomain.com/here/there?everwhere

    I supect there are a number of ways of tricking Zope
    into accepting URLs in the first form, or perhaps
    into actually generating some static pages which would
    be served up directly by the HTTP server (though
    my quick check of the archives suggests this is an
    unresolved issue). My questions are:

    1) Has anyone already done something like this?

    2) What approaches could you suggest to accomplish
       this?

    3) Is trying to arrange this likely to be a big task
       or a little task (as subjective as that question is)?


B) On another topic entirely, I am wondering about the issue
of tracking sessions of end-users.  (Hmmm... maybe I should
have done more searching in the archives -- this must be
a common issue.)  Various application servers (e.g., for
Java servlets) that I've looked at provide facilities
for maintaining "session" information (not in the sense
of a transaction as used in Zope) about end users.   Typically
this would be done by setting a cookie or by incorporating
a session ID into dynamically generated URLs.  I haven't
noticed anything about this in the Zope documentation.
I'm guessing that perhaps that is because Zope is so
powerful that implementing something like this yourself
is regarded as trivial.  But thinking about it a bit,
I'm not sure what the Zope mindset would be about how
to do this.  Zope sends requests directly to objects.
But in order to manage a session cookie (or whatnot)
you need to add a certain functionality to every (or
most HTTP) requests.  You certainly don't want to have
every object explicitly worry about this.  Is there
a hook that would allow all requests to
pass through some sort of filter that extracts/manages
session information?  Or is there some other standard
solution to this problem?


For what it's worth, I am interested in using Zope
to build my second E-commerce site.   I built the
first site by using Python to generate static pages
from a data structure, combined with lots of JavaScript
and a little Perl CGI.  It worked, but I'm sure there
is a better way.  I was leaning towards a Java servlet
plus templating package solution, until I found Zope.
I've been a Python proponent for a while, but Zope is 
threatening to make my brain explode.  Talk about 
paradigm shifts. 

C) Despite my Python and OO background,
it's not easy to absorb it all at once.  This does
make me somewhat concerned, as my business partner,
who will be a content provider, has no OO experience.
I don't want to produce a system where it will be
hopeless for her (possibly with help from another
developer) to take over if I get hit by a bus.
Thoughts...?

Robert,

I'm only going to address your last point, but it's 
something I feel strongly about.

Let's ignore the technical issues, except to mention
that only you can judge is Zope is appropriate for
your situation.  Fortunately, you have an excellent
opportunity to discover its relative strengths and 
weaknesses.

One of the important secondary issues (some would 
claim the primary) about Open Source is that it
protects your business against the "What happens if
Robert gets hit by a bus?" scenario.  Digital Creations 
is in the business of providing support to organizations 
that use its products.  Heck, in this sense it's even 
superior to key man insurance.

Furthermore, because of DC's courageous decision to 
release Zope as Open Source, not only is your company 
protected against *your* untimely demise, but it's even 
secure against the day Hadar decides to transfer all 
the company assets into hedge funds.

Best regards,

Message-ID: <EF3E7C5CCD67D211A43C006008AE49B8181FF7@JUNG>

Hi All,

As an exercise, I'm trying to get the JobBoard example code given in
http://www.zope.org/Documentation/Reference/ObjectPublishingIntro to work in
Zope (as opposed to Bobo/ZPublisher), and am having some difficulty.

Copying the PeeWee's playhouse example in
http://www.zope.org/Documentation/Reference/ExternalMethods, I placed all
the JobBoard files in zope/lib/python/shared/JobBoard, made an empty
__init__.py file, fixed up the dtml_loc variable, and put a
JobBoard_utils.py file into zope/extensions, which reads as follows:

  "utility to add JobBoard objects to folders"

  def addJobBoard(self,id):
      "Add a playhouse to the current folder"
      if not hasattr(self,id):
          setattr(self,id,JobBoard("Python Jobs"))
          return "JobBoard added with id %s" % id
      else:
          return "id %s already in use" % id

Using Zope's management GUI, I successfully added the addJobBoard function
as an external method, and have successfully called it to create a JobBoard
object called testJobBoard.

However, when I try to view the testJobBoard object, I get an error message
that reads "Sorry, the requested document does not exist."

The addJobBoard function was added as an external method to the root folder,
so my understanding is that the testJobBoard object should also be
accessible from within the root folder (that is that its URL is
"localhost:9673/testJobBoard").

What am I doing wrong here?

Also, what is the proper way to debug this sort of problem?  The output of
the zope process merely mentions a GET request for the given URL, and the
404 response code -- no further detail is given.

Thanks in advance for the help!

In looking through my Apache configuration files, I tried to piece
together what changes I made. Here's what I think you need to do.

In httpd.conf, make sure you have these lines (I put them at the end):

Alias / /cgi-bin/Zope.cgi

# Zope configuration maps /Zope/ to the Zope.cgi CGI script
RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

NOTE: In the RewriteRule directive above, the [e=...] stuff should go
directly after the ...Zope.cgi/$1 section, with a space separating them,
e.g. ...Zope.cgi/$1 [e=HTTP...]

You will need to munge the path in the RewriteRule directive, where it
says /home/httpd to be wherever your document root is.

I did this a while back, and have since switched from Apache to ZServer to
test it out, so I haven't used it lately. However, this should work, as I
never changed the config files after I stopped using Apache.

Let me know if you have problems; I'll do what I can to help.

I think you need <!--#var img.name-->.

wading through one message at a time over the

I haven't discovered how to get a listing of

Thanks

You say "one shouldn't have to use <!--#var "_['foo']"--> instead of
<!--#var foo-->."
However, i find it useful to write:

<!--#if "_['foo'] and _['bar']"-->
<!-- blah -->
<!--#/if-->

instead of:

<!--#if foo--><!--#if bar-->
<!-- blah -->
<!--#/if--><!--#/if-->

Hope that helps...

<!--#var "img.name"--> is the best way to go. It'll insert a IMG tag with
an absolute URL, and if it knows the image width and height, these will be
included in the image tag. Make sure you use the quotes! img.name means:
the attribute 'name' of the object called 'img'.

You can specify the image width and height by hand in the images' property
screen, but if you uploaded a PNG or GIF image, Zope will deduce the width
and height from the image itself. The next Zope release will also support
JPEG image size detection.

Yes, that's what I want. 

Maybe what I'm trying to do is against object-oriented concept? I can
see that images should be kept with the DTML page that calls them. I
just need images to be accessible by a group (role) of "image managers",
but the code that holds it to together should be accessible to an Admin
role only.

There is little reason to avoid naming your objects with the extension
built into the ID, like everywhere.html. You can then simply refer to the
object using that ID, which to a not so smart indexing bot will look like
an HTML file (but it should *really* look at the MIME-type...). The only
problem would be referencing the object, as you have to take precautions to
make sure Python doesn't try to reference the attribute named 'html' on the
object 'everywhere'.

So, as long as you name your DTML Documents that are to be indexed with the
.html extension, everything should go fine.

No, Zope has no Session tracking facilities at this moment. DC is however
working on this. At the moment you will find a 'Session' object in your
Zope distribution, but this is a different concept altogether, and will be
renamed to 'Version' when client session objects appear.

DC can be hired to help out... and as Zope is now Open Source, a growing
number of people can help out.

How about 

<!--#if "foo and bar"-->
<!-- blah -->
<!--#/if-->

or 

<!--#if "_.getitem('foo', 1) and _.getitem('bar', 1)"-->
<!-- blah -->
<!--#/if-->

So we can confuse each other even more =).

Yep, you got use there.... calling the Image object doesn't generate extra
information like border=0. DC is working on a solution to that, at least, I
think they said so.

For now you will have to write out the IMG tag yourself:

<IMG SRC="<!--#var BASE1-->/img/name" width="<!--#var "img.name.width"-->"
height="<!--#var "img.name.height"-->" border=0>

I assumed that the img Folder object is a direct subobject of the Zope root
object.

I was afraid it would be the case.... I thought I could use Property
somehow (adding text Property named Border with the value 0) but then I
realized that I can't interfere with it, since the rendering takes place
INSIDE while properties are OUTSIDE.

> <IMG SRC="<!--#var BASE1-->/img/name" width="<!--#var "img.name.width"-->"

Looks terrible :-) I think I rather use <img src=img/name border=0> for
the time being.

okay next qustion: I have a image under a folder called "images".
<!--#var "images.somefilename"--> should work - except that the image filename
contains the "." character (eg: "foo.gif") and this gets confused with the dot
notation of the object (it tries to find images/foo/gif and chokes with a

So how do I get round this one?

How do you do this?, ie to get a list of files/objects  that contain

I don't mean the 'find' tag in the manage screens, by the way...

Subject: [Zope] File upload product anywhere?
Message-ID: <v04104401b312cbb2cbde@[128.240.198.13]>

Hi all,
Has anyone written a file upload 'product' that they'd like to share?

My own requirements are that;
the files should (optionally) go to a file system,
I need to be able to change the interface for the system,
the users should be authenticated from an external database,
the files (if held in a file system) should retain their associations 
with folders (for permissions and access),
and I'd like it in blueberry please.

What I'm basically after is the best of both worlds - Zope 
permissions/acquisition etc. with the 'safety net' of a file system 
for large files (and possible batch uploading).

My problem (or one of them) is that there's no way that I'm up to 
speed enough in Zope/Python to start on this...I have a system doing 
the file upload working well in PHP3, but that (obviously) doesn't 
have the permissions/acquisition power of Zope. I guess I could do 
redirects to my PHP3 scripts from within Zope however, but it's 
hardly (ahem) 'elegant'.

any thoughts gratefully accepted.

The find management screen does give helpful hints. If you want to
implement this kind of searching, you'll have to use the same techniques.
These are however largely undocumented.

The file lib/python/OFS/findResult.dtml should give you a lot of hints on
how to implement a search command. It comes down to calling PrincipiaFind
on a Folder with the right arguments:

obj, obj_ids, obj_metatypes, obj_searchterm, obj_expr, obj_mtime,
obj_mspec, obj_permission, obj_roles, search_sub, REQUEST, result, pre

where

* obj -- base folder to start at

* obj_ids -- (optional) list of object ID's to search

* obj_metatypes -- (optional) list of meta types to search for (if the
string 'all' is in this list, all objects, whatever their meta type will be
included in the results).

* obj_searchterm -- (optional) literal text to search for in the *source*
of DTML Documents and DTML Methods.

* obj_expr -- (optional) DTML expression (as would be used in the expr
attribute of for example the var tag). If this expression returns true
within the context of an object, the object is included in the search
results. You could use this for testing on certain properties, like 'foo=bar'.

* obj_mtime -- (optional) DateTime object or string that can be converted
to a DateTime object, specifying a modification time to compare objects
against. Will on default return objects that have been modified since
obj_mtime.

* obj_mspec -- (optional) When used with obj_mspec, and set to '<',
PrincipiaFind will only return objects which have been last modified before
the date and time specified by obj_mtime.

* obj_permission -- (optional) To be used together with obj_roles. Check if
the roles specified by obj_roles have the obj_permission permission. Only
these objects are included in the results.

* obj_roles -- (optional) List of roles to check for obj_permission access.
See obj_permission.

* search_sub -- (optional) if true, search subobjects recursively.

* REQUEST -- (optional) REQUEST object, used to make sure that
AUTHENTICATED_USER is available for obj_expr expressions.

* result -- a list of objects to be included in the returned results. Used
by the PrincipiaFind method when recursively searching subobjects.
Generally of no use to us humble DTML programmers.

* pre -- prefix the IDs in the returned result list with pre and a slash.
So, when called with pre='foo', and bar is the only object found,
PrincipiaFind will return the list of tuples: [('foo/bar', foo)]. This
argument is used when recursively searching subobjects, where pre is the
relative URL of the object searched.  Generally of no use to us humble DTML
programmers.

The method returns a list of tuples, where the first element of every tuple
is the relative URL of the object found (relative to the starting point),
and the second element is the object itself.

Object name can be different from filename. Thus you name your foo.gif
file just Foo, and that's it.

Zope's object database uses Python's pickle facility, so in general
instances only store their own data, and use whatever version of the class
is available. Classes are not stored in the database. This means that when
you change your class, your instances will be updated.

>Also, is there any problem with the instances failing to work with a newer
>product version?

Yes. And this is not a Zope-specific issue, or even a Python-specific issue.

Anytime you have long-lived instances and change the class, you may run
into problems. Python comes with a couple hooks to help you out. You should
look into __getstate__ and __setstate__ which are documented in the Python
pickle documentation.

Probably the most common type of problem occurs when your new class
definition assumes a new attribute which the old instances don't have. An
easy way to solve this is to provide a class attribute which gives a
reasonable default for this attribute.

For example:

class MyClassV1:
  'Original class'

  def __init__(self):
    self.color='red'


class MyClassV2:
  'Updated class'

  def __init__(self):
    self.color='red'
    self.texture='bumpy'

  def describe(self):
    return 'I am %s and %s' % (self.color, self.texture)

Notice that instances created with MyClassV1 will not have a 'texture'
attribute, so that when the class is updated, old instances will break when
you call the new 'describe' method. A simple fix is to provide a default
class attribute. For example:

class MyClassV2:
  'Backward compatible updated class'
  texture='nondescript'
  ...

Now old instances won't break in the 'describe' method.

Another approach is to test for the attribute and update the instance when
you're going to use it. For example:

  def describe(self):
    if self.texture=='nondescript':
      self.get_texture()
    ...

If 'describe' is the only place where you use 'texture' then you wouldn't
even need to provide a class attribute, and could simply test for the
absence of the attribute.

Finally you might include version numbers in your instances and test for
these, but this seems like overkill. I would suggest sticking to default
class attribute solution for most cases.

Hope this helps, and good luck.

In general, when you have trouble spelling an object's name in a variable
expression because its name is not a legal Python name (e.g.
'sequence-item' or 'foo.gif') then you should use _[] or _.getitem

However in your case you can simply get the sub-object with a plain old
getattr:

<!--#var "_.getattr(images,'foo.gif')"-->

Another possibility is to use the with tag:

<!--#with images-->
<!--#var foo.gif-->
<!--#/with-->

Since these are so ugly, you might consider the simpler manual method of
generating the img tag:

<img src="images/foo.gif">

or else you might consider *not* having a images directory, and keeping
your images in the Folders where they're used. Then you can refer to the
images directly:

<!--#var foo.gif-->

And because of acquisition, foo.gif is accessible to all sub-Folders of the
Folder it is located in, in the same way.

I tried both.

I'm sure I must be crazy. I summarize what I did:
1. downloaded fsimport.py
2. mkdir /usr/local/zope/Extensions
3. chown nobody:www Extensions
4. chmod /usr/local/zope/Extensions to be rwxr-xr-x
4. copied fsimport.py to /usr/local/zope/Extensions
5. chown nobody:www fsimport.py
6. chmod fsimport.py to be rw-r--r--
7. created External method fsimport inside of ppm
8. put "fsimport" into all 4 fields (Id, Title, Function name, Python
module name)
9. http://www.sol.cz/Zope/ppm/fsimport?fsdir=/home/pes/public_html
10. error "TypeError: read-only buffer, class"

I must have missed something.

Perhaps I'm failing to understand something.
Looking at pages on zope.org and some obviously dynamic pages
on other sites, they all return a MIME-type of "text/html".   Which I
think means that a smart indexing bot should *not* simply look at the 
MIME-type.

As I understand it, most search engine robots try to exclude dynamic
content because of the justifiable fear that once they start exploring
a web of dynamic content they could get lost in an infinite or
near-infinite search space.  I've read that as a result of this, 
search engine robots do things like refuse to index any URL with 
"cgi-bin" in the path, or which do not end in an approved recognized 
file extension.

Do you have a different perception of search engine robot policies/strategies?

Are there any projections available re the timing of this?  I'm wondering
about how much effort to spend on ad-hoc interrim measures.

FWIW, in my mind an ideal client session scheme would allow multiple strategies.
In most cases using cookies works out for the best, but I would like to be
able to accommodate anti-cookie zealots as necessary.  On the other hand,
I don't want to clutter URLs with session-id's if I don't need to.  (I suppose
having authenticated users is yet another strategy, and one that Zope currently
seems oriented towards.  Fine if users really want or need to get into your
site or need to perform authorized operations, but not so good if you're trying 
to entice them in.)

The problem is: it's not working.

I'm using the Zope HTTP server, and I can contact the

at everything.  But if I try to add an object (whether
it be a DTML Document, a Folder, or an "Item" from
the sample_product package (which I installed), what
happens is:

	I am allowed to fill out the form where
	you enter object creation fields (ID, title, etc.),

Any clues as to how to fix this, or debug it, or get any

<!--#in "objectValues()"-->
<!--#with sequence-item-->
<a target="_view" href="user/<!--#var id-->"><!--#var title--></a><br>

<!--#/with-->

However, I get a TypeError on the #with line (and even if I put in the

What am I doing wrong here? I've tried a lot of different combinations
of #with and _.getitem and such..

Victor,

I think your problem lies elsewhere.  The client does not
have to bind a local address before calling connect.  The
connect() function automatically assigns an unused port
to the socket.

You will probably find the problem is much more obvious
than a low-level socket bug.  Check your Zope.cgi paths,
permissions, and Apache configuration.

Good luck.

Subject: [Zope] setting variable
Message-ID: <199903160352.WAA04182@mail.digiweb.com>

Hello folks,
I'm stuck on a problem which I hope some one could help me with.  I 
have a database entry form where the user will enter in information for 
two related tables.  When she submits the form, I want to first post one 
tables information, then call another sql method to get the id generated 
for that post, then take that value and add it to the REQUEST object 
and pass it to the second sql insert for inserting to the second table 
(along with some other parts of the REQUEST object from the form).  

I'm planning on using MySQL that has a special select:
select LAST_INSERT_ID()
to return the last auto-generated id value to get the id.

I know you can add a variable to the REQUEST object via
<!--#call "REQUEST.set('varname', value)"-->
but how to I get the value from the sql method?  The only way I know 
now is via #var tags but you can't nest the DTML.

I hope this makes sense...

This is something Zope can´t influence, it´s part of the way your browser
works.

Could you supply us with some DTML examples of this behaviour? It´s not
something I´ve seen before. Is there any chance your HTML editor is doing this?

[snip external method]

I'm wondering; is there a reason why 'range' isn't accessible from DTML
in the '_' namespace? Is the reason as you indicated in your external
method, i.e. that you don't want people to generate vast ranges from
DTML?

Just curious,

The reason if of course merory flooding attacks. A range that asks for a
list of 3 billion items is a wee bit unpolite to the machine.

A way of checking would be:

RANGELIMIT = 1000

def SafeRange(iFirst, *args):
    if not len(args):
        iStart, iEnd, iStep = 0, iFirst, 1
    elif len(args) == 1:
        iStart, iEnd, iStep = iFirst, args[0], 1
    elif len(args) == 2:
        iStart, iEnd, iStep = iFirst, args[0], args[1]
    else:
        raise AttributeError, 'SafeRange() requires 1-3 int arguments'
    
    if iStep == 0: raise ValueError, 'zero step for SafeRange()'
    
    iLen = int((iEnd - iStart) / iStep)
    if iLen < 0: iLen = 0
    
    if iLen >= RANGELIMIT: raise ValueError, 'SafeRange() too large'
    
    return range(iStart, iEnd, iStep)

Maybe this should be part of the _ object. Can someone turn this into a
patch and supply this to DC? I´m a bit short of time right now.

Dear Zopists,

    This is another post to make you aware of a new source of
information for Zope. You can access #zope on the EFNet servers. Their
is an infobot on this channel that could be a great resouce, but it
needs to learn a lot about zope. If you pay a visit to the channel,
query the bot by typing:  /msg wizkid1 help. This will provide more
information on the bot.

I for one think this is a brilliant idea!

friendship can be built.

I really do hope this comes off, so let's make a go of this eh guys 8^)

Ok, two questions

1. What happened to the Zope web site, it seems to have gone down 
yesterday and still is not operating ?

2. I have downloaded ungziped and untared (Zope-1.10.2-linux2-x86.tgz), 
but the install instructions do not seem complete.  I retrieved the 
INSTALL.TXT file from the doc directory and started to follow them, but 
their doesn't seem to be any 'access' file in this distribution.  What's 
more some of the command line options come up as invalid, like -c,which 
the install program quit on saying it was a invalid option.  The -c 
option doesn't even show up in the --help for the installer.


I was hoping there would be some additional install info on the web site, 
but that's not working.

Try:

select LAST_INSERT_ID() as fred

then grab <!--#var fred-->

If this works then I know what the problem is!  :^)

If you use the database's command line tool and run this SQL statement I
bet it returns a single value (i.e., it doesn't return a table).  The DA
wants to munge and chew on rows in tables.  If think that if you use the
select LAST_INSERT_ID() as fred you'll get a one-row, one-column table
-- this is what Zope wants.

It works from where I'm at. You may want to try
traceroute www.zope.org
(or tracert www.zope.org from Windows)
to see where things are getting hung up.

The access file just needs one line of the format "username:password"
and should be in your zope install directory. Since I was using PCGI
with Zope, all I did was just untar it, make it and then copy Zope.cgi
into my web area...

Try: select LAST_INSERT_ID()+0 to cast it to an int...

Also, check your declaration for LAST_INSERT_ID().. if the above doesn't
work you'll need to either try the patch for ZMySQLDA that was posted a
week or so ago, or do something like: SELECT CONCAT(LAST_INSERT_ID()) to
cast it to a string and then use a nifty Python fn. to convert it to an
integer number. 

It seems the MySQL driver has problems with some datatypes.  There was a
patch posted befure.. I'm curious to know if it'll fix this problem...

This is in the Zope FAQ, actually, at http://zdp.zope.org/FAQ/external.
At least I think I'd apply to ZPublisher as well?

How do I return an image from an External Method?

Example (for a png image):

    def foo(self, RESPONSE):
        # set the header
        RESPONSE['content-type'] = 'image/png'
        # return the actual image data
        return mkimage()

Another way to set the header information is:

    RESPONSE.setHeader('content-type','image/png')

Regards,

Martijn

You are right. I wanted to check the frame, which I can't do easily
under Netscape, so I pushed File/Edit Frame, and apparently Netscape
Composer did it, because when I do "Save frame as...", it looks O.K.

Having discovered this, there is no chance I would ever use Composer. I
would be happy to have Zope work as closely as possible with
Dreamweaver, though.

I've been using this.... (Zope example but should work with ZServer)

It was fully expecting to have to mess about with headers to get browsers to
recognise the gif, but broswers seem to know a gif when they get one!

This example returns gifs in a browser when you do ....

http://mysite/renderGif

or even

<IMG src="renderGif">

(I'm fully prepared to admit there may be better ways of doing it) ;)_

Cheers,

Andy.

    def renderGif(self, size=500, counter=1):
        """Draw a pie chart"""
        im = PIL.Image.new('RGB', (size,size))

        # Do GIF manipulation stuff here!

        outFile = cStringIO.StringIO()
        im.save(outFile, 'GIF')

        outFile.seek(0)
        outString = outFile.read()
        return outString

Why not use:

select 'id_field_name' from 'table' where 'id_field_name' IS NULL

id_field_name beeing the field with AUTO_INCREMENT set

When using Zope to publish XML documents (using DTML Document objects) I
often write:

  <!--#call expr="REQUEST.setHeader('Content-Type', 'text/xml')-->

Some part of Zope tries to guess the Content-Type otherwise. A lot of this
code is directly shared between Zope and Z Publisher, so you might see
similar behavior.

Eric

Message-ID: <36EEBBF1.B7B05990@netscape.com>

Ok, I consider myself pretty technical, but not a UNIX master, and I've
used NT enough to know about services, etc.  But I cannot for the life
of me figure out how to get zope running as a service without manually
starting it from start.bat.


Could someone please post somewhere a "zope for dummies" description of
getting zope running as a service on NT.

Here's what I do:

I downloaded zope 1.10.2
I unzipped and ran the installer.
It works fine to the point where it wants me to choose between running
zope alone or as a service.
I've tried it "both ways" and although I can get zope running fine by
manually starting it from start.bat, and
I make the zope service start automatically, it will not work as a
service!

I dont have any other web server on this machine and dont really care
which server I use. I had assumed that ZopeHTTPServer  would run as the
service, but it doesnt work...

Is there just a minimal way to get zope going on it's own?

I know the ip address etc. of my system, but that doesnt seem to be the
issue.

I wouldnt even mind if in the install you had an option for "install
default web server" so that zope can piggy back on it.

Does it have something to do with setting permissions to the var
directory?

All I'm basically looking for is sort of a recipe style instruction on
how to get it up and running. (With no handwaving like "now configure
your system to run the zope.exe".  Assume I'm a total idiot...

Which I'm not, but I'm still having problems.

No, I don't think that can work. You need another webserver, like Apache
(which you can download from www.apache.org, though of course it has its
own configuration hassles).
 
> Is there just a minimal way to get zope going on it's own?

Hm..Perhaps ZServer, but that's still not stable. Can it run as a
service in NT?
 
Otherwise I'd recommend Apache; it can do plenty, though there is a
learning curve there.

Here's what I did:

I downloaded zope 1.10.2
I unzipped and ran the installer.
I chose to run zope alone
I created a shortcut to start.bat in C:\WINNT\Profiles\All Users\Start
Menu\Programs\Startup


This will start Zope every time you reboot. Note that it will not get
rid of the annoying MSDOS command prompt window.

I hope this helps

I posted a message last week about running ZServer as a service.  You can
find the message at
http://www.zope.org/pipermail/zope/1999-March/005030.html

I built my Zope from source, so I don't know if this works the same as the
self-installer version, but it should be pretty close.

1. Install Zope 1.10.2, choosing to run standalone.
2. Untar the ZServer distribution in the root Zope directory.
3. Test that it works by running start.py in the ZServer directory.
4. Follow the directions in the message linked-to above.

Well, try something like:

<!--#in lastInsert-->
	<li>The id last inserted is <!--#var new_id-->
<!--#/in-->

where lastInsert is your SQL method

Note this is untested code, so caveat emptor :)

I found some examples of their use, but nothing definative.

I have no problems reading the source and documenting what I find, I just

Do you really need this? You can put more than one sql commands in a sql
method, you just have to put a <!--#var sql_delimiter --> between them.
You can insert in the two tables with just one method. The
last_insert_id() should be in the values field of the second insert.
Take a look at the code genereated by the sql wizard in the contrib
page.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <36EEE8E7.11F8DBC@erols.com>

Right now my biggest obstacle to setting up a Zope-powered
site could be finding a hosting provider I have confidence
in who is willing to run Zope.  When I asked my first-choice
provider about running Zope, they replied:

> Though it's true that we can install programs that need root
> instlall, it only so when the program is low CPU/mem use and
> non-intrusive. Zope is neither, so to run it you would need to get
> your own dedicated server through us.

A dedicated server is not a viable option for this site at
this point in time.  So, a few questions:

1)  Are the provider's fears justified?  What sort of
    memory footprint, CPU requirements (for a site that
    should have fairly low traffic at first), and other
    impact are Zope likely to have on a hosting provider?

2)  Would anyone care to let me know what their experience
    has been with the two hosting providers (NexusWeb and

Hey Paulo, thanks for that tip.  I didn't know about #var sql_delimiter 
and the ability to put more than one sql commands in a sql method.  I 
had wondered about it but the #var sql_delimiter was the key.  With this 
information, no I don't need to insert into the REQUEST object.  But I'm 
still curious <g>.

Unfortunately, putting last_insert_id() directly into the values of the 
second insert did not work.  It works from mysql command line.

<!--#var sql_delimiter -->
INSERT INTO entry_tbl 
	(master_id,submitted_by,staff_id,version,comment)
	VALUES (LAST_INSERT_ID(),
		<!--#sqlvar entry_tbl.submitted_by type=int -->,
		<!--#sqlvar master_tbl.entered_by type=int -->,
		<!--#sqlvar entry_tbl.version type=string optional-->,
		<!--#sqlvar master_tbl.comment type=string optional-->)

It surprised me that it didn't work as I thought it would get sent enmass 
to mysql for processing so I had thought that the DA wouldn't interfer 
with it.

Subject: [Zope] newbie -  permissions on FAQ object
Message-ID: <199903170144.SAA26992@stout.atd.ucar.edu>

I'm trying to configure a ZOPE FAQ object on starship.python.net .

This is Zope v10.10.2 with ZServer 1.0b2 .

I'm baffled by the permissions scheme.  I've created a FAQ under my
ZOPE home:
http://starship.python.net:9673/crew/vanandel

I'd like selected users to add FAQ entries, but only certain trusted 
users to be able to create categories.

Unfortunately, anyone can add a new category, which is not what I want.
The Security Screen for vanandel/NumPy only enables 'view' for 
anonymous, but still an 'anonymous' user can enter the 'Add a category' 
screen, without being challenged.
There are specific permissions shown for various "add-ins" 
like TinyTables on the Security screen,
but not for the FAQ module.  (I'd expect to see permissions for 
FAQAddCategory.)

Also, when I first create a 'FAQ', I can't view it until I create
a 'isCategory' property.  This seems like a bug, since 'isFAQ' is 
already created for me.

A minor question.  I'd obviously like to test ZOPE with various users,
to see what ZOPE allows them to do.  ZOPE uses cookies to give someone 
permission, after they've supplied a password.
Under Unix, I can manually remove a cookie by editing ~/.netscape/cookies.  How do I do this under NT?  Are Netscape cookies in the registry (I hope not!).

Thanks much for your help.

Excellent.

We here at DC (well, I'm out of the office this week, but I'm there
virtualy) have been kicking around an LDAP authentication mechanism,
probably a folderoid, to go against LDAP.  In fact, this was supposed to
be one of my projects when I get back next week.  From the details below
it looks like you have thought this out well, I didn't even consider
making an API of methods like XSQL methods, good idea!

Under the catagory 'result caching' you might want to consider making some
kind of Connection Manager in your LDAP Connection.  A model I've been
kicking around is a CM class that manages Connections and uses a simple 
caching algoritm.  Wrapping all of the API in a class will also help yu 
when you want to break out the LDAP stuff and stick it in shared.  In
this way, it becomes a sort of 'Device Driver' (to use Ken's
terminology) for the entire Zope system.  We're going to be doing this
with the IMAP functionality that NotMail uses.  I'm assuming what
you call an LDAP connection is like a Database Adapter is to ZSQL methods.
Maybe you might want to consider calling these LDAP Adapters.

The etcUserFolder product has a settable property to change the 'default

Don't hurt yourself.  It looks like you got this down pretty good, I'll
proablby be looking into incorporating much of this if not all into Zope,
want to be in charge of zope LDAP?  We can give you an area on the site.

Subject: [Zope] recursive document oddity
Message-ID: <Pine.LNX.4.05.9903170107540.673-100000@web.spyderlab.com>

Hey zope freaks:

Okay, I am driving myself crazy, maybe I am just doing something silly
(hopefully).

I am trying to write this recursive SQL result DTML (basically a tree):

<!--#in listCategories-->
  <p>Category <!--#var nm-->
  <blockquote>
  <!--#var recurseCategories-->
  </blockquote>
<!--#/in-->

I have a variable pwd that I want to pass along to recurseCategories..

I tried something like <!--#var recurseCategories(pwd=catID)--> (and in
quotes)

pwd is used in listCategories to get a list of categories in that 'path'

A couple questions:

1. Should I be using a DTML method or a DTML document for something like
this?

2. As I recurse will I lose access to documents in my current folder? I
got a traceback to seemed to indicate that once I was into a certain
depth I couldn't access listCategories.

3. Is there a more Zope-happy way to do this?

OK, so it still does not work for me. If someone on this conference

This is good for ZOPE newbees who wonder what and
why about Python (The underlying language of ZOPE).

Title: "Python, anyone? "

You may have dismissed Python as just another scripting language beginning
with 'P,' but more and more open source developers are finding Python has
some bite

Summary

At first, the Python scripting language may sound like another version of
Perl, but Robert Richardson highlights the differences that make it useful
in its own right. (1,500 words) By Robert Richardson

Probly I misunderstod your problem.

Anyways I want to say that my suggestion does just what 'select
last_insert_id()' does. namely return the number created in an
auto_increment field during your last insert

My profound apologies.  "select <field_name> from <table_name>  
where <field_name> IS NULL"  does indeed return the same value as 
last_insert_id().  My apologies again.

Hi All,

I'm just uploaded a new Product to the contrib area.

It is a poll product based on Amos's example. It uses PIL to draw
piecharts of the poll results.

I was originally going to include a precompiled PIL with the product, but
the
product swelled to 500k as a result, so instead I've left pointers to where
to get PIL in the product documentation.

I'll send a hypertext screenshot immediately after this message so that
people can decide whether or not they want to go to the effort of
downloading and installing PIL.

Pls note that there are some problems I'm having with getting the GIFs to
update appropriately, so after banging my head against a wall for a while
[in true opensource tradition ;) ] I've decided to throw it open to the
floor to see if anyone can find a workaround.

I've also uploaded a 'fixed' version of the Guestbook example product, which
broke going from Zope1.9 -> Zope1.10.

Enjoy!

Andy.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <000701be709e$ea4cd4c0$642fe18d@jharris.coe.memphis.edu>

I contacted NexusWeb yesterday and they said they would provide a setup for
Zope, but no support.  They were not specific as to the setup.  They did
mention they supported Python.  I was going to write them back to see if
they ran Zserver, or just provided the links to Apache.  They did have msql
and mysql.  The minimum plan to support Zope was the 50MB/$20 a month plan.
The other site was out of my price range ($50/mo).

I just started studying Zope yesterday to use for a project I was planning
to use Visual Basic/ADO/ASP for.  I'm testing on a Win95 machine, but plan
to move testing to a Linux box.

I decided before signing up with a hosting server to wait for Zope 2, which
I've seen a couple of references to.  What's the deal on that?  One place
promised a better integrated web server.  If Zope moves more torward being a
totally self contained server, then I don't want to mess with Apache or IIS.

Subject: [Zope] Newbie questions
Message-ID: <D133051DBC4AD111B90800A0C9694983A61695@natasha.auslabs.lucent.com>

Hi Zopesters,

I'm trying out Zope for the purpose of getting a book catalogue on the web.
So far, I'm extremely impressed with it! Of course, I have some questions.
(For the record, I am running Zope 1.10.2 with Apache 1.3.something on a
MkLinux DR3 box, administered with IE4 on NT).

1. When you edit a DTML document using the Zope management interface and hit
the update button, Zope goes away and tries to parse it to ensure that it's
consistent DTML. If this fails, you are left with no option but the
browser's back button, which, under IE4 anyway, seems to discard the changes
you made to the document. Is there a fix or workaround (besides ctrl-A
ctrl-C before clicking the update button) for this? Us newbies write lots of
bad DTML :)

2. When a folder acquires an index_html document from further up in the
heirarchy, the <!--#var title--> tag refers to the title of the index_html
document, rather than the folder being displayed. How do you write the
index_html document to display the title of the acquired object, rather than
the index_html document itself? (Hope this is clear)

3. Finally, I need some advice about how best to lay out the website.
Basically I'm trying to build a site containing a book catalogue. Here's
what I've got so far:

+ Root
	+ Titles [folder]
		- index_html
		+ OriginSpecies [folder, title: "Origin of the Species",
desc: "blah",
				author: "CharlesDarwin", year: 1854]
			- cover [image]
		+ DiamondAge [folder, title: "The Diamond Age", desc:
"blab",
				author: "NealStephenson", year: 1995]
			- cover [image]
		...
	+ Authors [folder]
		- index_html
		+ CharlesDarwin [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]
		+ NealStephenson [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]

Hope the notation is clear enough. What I want to do is "link" the titles to
their authors and vice versa. So the index_html document for Authors would
display the author, their picture, bio, and a list of titles by them. A
similar arrangement would apply for Titles.

The author property of the title (*) links the title to author, but what's
the best way to link backwards? Similarly, what's the best way to display
the author's information for a title?

All advice appreciated! Thanks.

(*) assuming only one author for now

Subject: [Zope] Newbie install help needed !!!!!
Message-ID: <199903172113.QAA02057@mail.howard.k12.md.us>

Thus far my attempts to install the Zope binary release on a Linux 
machine have been for nothing.  The Install documentation and the Install 
program contradict each other at almost every turn.

The docs say use ./install -u <userid>

but the -u switch is gives a error message, saying it is a invalid switch 
and not supported at all. The install --help, says nothing about a -u 
switch.

The docs say you can specify the cgi directory, with the -c switch, but 
the install program says that is a unsupported feature.

The -s switch in the docs says this is to provide the superuser login and 
password to the install routine, yet the install program say this is used 
to strip tables (perhaps parsing the access file), none of the docs say 
anything more.

I have tried numerous variations, all to no avail.  Perhaps the ZDP 
should have started at the beginning, with usable install instructions, 
instead of with a FAQ.

I must say that the screen shots in the PDF file and those docs are quite 
nice, but thats about it.  Reading the PDF docs, just makes me want to 
get in and try Zope even more.

Is there anyone that could help or give me some pointers ?

Tom

Subject: [Zope] multiple trees
Message-ID: <199903180035.QAA28795@christopherrobin.kolo.net>

There seems to be a problem with DTML documents which 
uses more than one <!--#tree--> .. <!--/#tree--> sections.  I'm
seeing a python error when attempting to expand any node of 
the second tree.  I'm going to try and fix this on my own as
a way to familiarize myself with Zope internals but I thought
others on this list might want to be aware of the problem and/or
provide information about their own experience with multiple
trees.

It's on the list. I was originally going to write a simple LDAP auth
object, then thought about it a bit more and realised a generic interface
into LDAP would be more useful, then I can bolt the auth on top.

The way I figure it, I'll support this first. If/when someone needs 
something else, I'll look at supporting that.

Not quite sure what you're getting at here :)

Hm. The LDAP connection already is a class. It's as much a device driver
as the current Database Adaptors.

Good point. Next version, they'll be called that. (I figure I'm allowed
to make changes like this between versions 0.1 and 0.2 :)

That and maybe allowing a mapping for any organizationalRole that 
the users have. More useful for the "lecturer", "student" type

I've got variable interpolation _mostly_ working. For some reason, though,
it doesn't pick up all the namespaces - I'm probably just not using 
the document templates right. I'm going to add DTML interp. to both the
filters and to the baseDN.

Depends on my supply of round tuits - I might get the pluggable brains
also working shortly. I kinda see how they work now.

Hm - depends if it's easier to get to than my current web site. :)

Message-ID: <Pine.GSO.4.10.9903181010060.29492-100000@bonnie.sz-sb.de>

We are running Python1.5.2b2 (with thread support) , latest DCOracle,
Oracle 7.3 under Solaris 2.5.1.

Some of our applications hang in about 10% when they run. We trussed
the binaries and discovered that they all sleep in a lwp_sema_p() call.
Python/thread_cthread.h seems to mention a problem with the Solaris
PThreads implementation however I can't figure out if this is the
real problem. I am not sure whether it's a problem of Python, DCOracle
or the Oracle libraries.

Any ideas or comments ?
Thanks,

Hi Thomas,

>Is there anyone that could help or give me some pointers ?


Yup, those switch options are confusing so I avoid them ;-)

First, the most helpful tool for me in working with Linux is
"git".  This is a nice character based navigation and file
management utility.  Just type git.  It came on my RH Linux
and is installed automatically without your request.  This
program is alot like the DOS Norton Commander that
I started using years ago.

So you get the distribution:
  Zope-1_10_2-linux2-x86.tgz
I use git's F6 key to rename it zope1102.tgz
to ease the long typing.
Move it to a newly created directory (F7)
named perhaps "zope". 

Then in that directory, type: 
    tar -xvzf  zope1102.tgz
A new directory is then created under your
new zope directory named:
  Zope-1_10_2-linux2-x86.tgz/
Go into this directory and type

***This is were you got stuck***

./install

***No switches!!!

Then edit the access file now in
this directory and change the obscure
username and password to your favorites
with F4 key to use "vi"  Press  i to 
insert new user/passwrd -- example:
  zope:gogo
Press escape then :wq  to save.

Then 
  ./start 
to start zope
and maybe later if you EVER want
to stop zope (who would ever WANT
to stop!, 
  ./stop.

BTW,  if you want to test the integrity
of the downloaded zope distro, only change
the t to an x as in:
    tar -xvzf  zope1102.tgz

Enjoy!!!

Ok, unstuck, whoops, stuck again.

I guess I have to do this in little baby steps.  Some sort of initiation 
ritual, I think. ;-)  Now I am getting the error message below even 
though python is clearly in the bin directory under the Zope install 
directory.

"./install: bin/python: No such file or directory"

This is the shell install script:


***
#!/bin/sh

# Get script dir
if [ -n "`echo $0|sed -e 's%[^/]%%'`" ]; then
  PYTHONHOME=`echo $0 | sed -e 's%/[a-z.]*$%%'`
  cd $PYTHONHOME
else
  PYTHONHOME=.
fi

export PYTHONHOME
bin/python inst/product_install.py $*
***

A little different than the PERL I am used to seeing, but I've managed to 
make heads-and-tails of the thing.


- I checked the location of python in the Zope install dir, ok.
- I checked to ensure that the sh shell was in the bin/ dir, ok.


Next up, re-upload the Zope file and check for a corrupted archive.


Any other ideas ?

Hope you don't mind me butting in, but if you just want to check out Zope
very quickly, run the Windows version on 95/98/NT.  It was nothing to
install, and I was playing with Zope two minutes after downloading it.
Python is also a snap to insall on Windows.

Subject: [Zope] Parsing XML into/out of the database
Message-ID: <199903182236.WAA24270@cheviot.ncl.ac.uk>

Hi all,

I have an application that consists of 140+ XML documents, roughly 100k
bytes each that I want to be able to query (using XSL pattern matching at
present) and output to XML/HTML and RTF format. This will happen in real
time (if at all possible).

At the moment, my XML documents are held as files in a real file system
(sacrilige! :). However, I'd like to get them into the database structure if
at all possible, as I imagine it will make things easier in terms of
searching. For example, the XML file

<?xml version="1.0"?>
<document title="Cell Biology">
<topic title="introduction" id="cb1">
    Cell Biology is a good thing. If it weren't for Cell Biology, you
    wouldn't be around.
</topic>
<topic title="lectures" id="cb2">
    <topic title="lecture" id="cb2" num="1">
    This is lecture 1.
    </topic>
<topic title="lecture" id="cb3" num="2">
    This is lecture 2.
</topic>
<topic title="reading list" id="cb4">
    <topic title="bok" id="cb5">
        A big bok
    </topic>
</topic>
</topic>

Would lend itself to creation in the Zope database really easily (I think).
XML elements (document, topic) and attributes such as id (used to uniquely
identify an element) and title would be properties of the DTML
document/method. So long as the id numbers were properly arranged, it should
be *relatively* (good word that!) simple to recreate the original XML
document. I assume that parsing the XML (in actual fact, the DTML doc/method
would consist of *very little* XML I think, it all being taken care of in
properties) to create HTML would be, again, relatively easy (my own tendency
is to use the 'title' attribute as a class identifier for cascading style
sheets).

My question is, do people think that this idea could fly? I have spent *a
long time* looking at how to get our Word (sorry for saying that!) documents
into a format that means they can be easily put into a database and thereby
benefit from all the good things that means. Several cul-de-sacs and wasted
weekends later, it seems to me that Zope is coming out to be the closest
thing to a solution for my problem...

(I know from off-list discussions that there's a definite 'weirdness' about
how people have been wanting/needing to implement things and then finding
that (a) Zope does it already, (b) there's a product available or (c)
someones working on it... !).

any thoughts, as usual, greatly appreciated.
tone.

Message-ID: <Pine.LNX.3.96.990318144553.4537B-100000@taos.kavi.com>

I've been messing around with using direct traveral on the ZSQL methods.
I'm having a problem getting the traveral to work with anything more than
one level of depth, eg:

http://zope.kavi.com/mem/2/comp_admin/contacts/

Where 'mem' is the ZSQL query (that takes one arg), and the arg is '2'.
But it does work in this case:

http://zope.kavi.com/comp_admin/contacts/mem/2/

Is this a restriction on the use of ZSQL direct traveral, or am I doing
something wrong.

If this is a restriction on how you can use direct traversal, I was
wondering why, and if it'd be possible to 'fix' this. If so, I'm willing
to do it and supply a patch, I assume this is functionality comes from
Zope/lib/python/Shared/DC/ZRDB/DA.py, either in the DA.__call__ or in the 
Traverse object. I'll have to mess around with it a bit to figure out
exactely whats going on (but I figured I'd ask about it first).

This is more or less what I did for my original FAQ product (but on a much
smaller scale). I found out XML docs map nicely onto Zope's DB structure.
I think you should give it a try because really it is not much effort to
implement.

Since the FAQ development has moved to zdp.zope.org my site is no longer
needed so I created a guest account with the following authentication
info:

guest
bobo

at URL http://www.gaaros.com:9673

You can visit it and see my approach to the problem. I should also include
the code of the external method that creates the Zope objects. (I believe
a couple of more zopistas asked me for source access so here is your
chance.) I have backed up Zope's DB so you can mess around as much as you
want.

Without seeing your folder hierarchy, I'm not quite sure what's going on.
Frankly, my head feels like it's going to explode when I try and figure
out how your second example even worked. What are comp_admin and contacts?
Folders? Where do they fit in your folder hierarchy?

I have an event calendar, in which I use direct traversal of a ZSQL Method
to display a particular event. My hierarchy is as follows:

+ events [Folder]
  - event_details_html [DTML Method]
  - dbFindEventById [ZSQL Method]

My dbFindEventById method takes on parameter, event_id. To use direct
traversal on my dbFindEventById query, using the event_details_html file
to display the details of the event with event_id of 2 requires the
following URL:

  http://localhost/events/dbFindEventById/event_id/2/event_details_html

At first, I tried:

  http://localhost/events/dbFindEventById/2/event_details_html

which looks very close to your first example, and it did not work. Then I
realized you are required to specify the name of the parameter in the URL
as well, so I added event_id before the 2, and I was off to the races.

I'm sure I've misunderstood your problem somewhere, and if I did, I
apologize for spouting off nonsense. But, I figured this just might help,
since I got tripped up when I first tried to use direct traversal, also.
Better safe than sorry. :^)

Ok, a bit more info...

mem 		ZSQL method (on top level - stands for member company)
+ comp_admin  	folder (company admin)
  + contacts	folder (contact info for that company)

contacts has an index_html which uses information returned from the mem
query (its not how I use it, it won't even display with just #var).

'mem' takes one argument: comp_id (of which 2 is a test case)

Actually, I've found the reverse to be true. When I try:

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

I get this error:

Invalid integer value for comp_id 

Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module
  File lib/python/ZPublisher/Publish.py, line 413, in publish

    (Object: <string>)
  File lib/python/Shared/DC/ZRDB/sqltest.py, line 192, in render
    (Object: comp_id)
ValueError: (see above)

If I use creosote.spew to output the comp_id value before calling the
query (I made spew an external method on the top level, this has come in
very handy), the value resolves to 'comp_id'.

But when I don't use the comp_id arg (like in the original example, and
spew shows the value to be 2), it works fine as long as the method using
it is the next on the URL.

Actually you are close, but in your example you use it as I said it works.
In your code app can you do something like this (fictional change of your
example):

http://localhost/events/dbFindEventById/ 
	event_id/2/modify_event/edit_event_details_html

(should be all one line)

Make more sense now?

BTW, thanks for the help. :)

Ok, I think I figured out why we have different (opposite) results in
this. I don't think you checked the "Allow direct traversal" checkbox on
the advanced management page for the ZSQL method. If I unchecked it, then
I could traverse like so...

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

After checking it, I could traverse in this way...

http://zope.kavi.com/mem/2/comp_admin/contacts/

Strange... :)

Still doesn't address my original problem thought. I still can't get
access to any of the results of the 'mem/2' query anywhere other than
directly after it (on the url). 

Ie. 

http://zope.kavi.com/mem/2/comp_admin/contacts/index_html 

Doesn't work, but...

http://zope.kavi.com/mem/2/test_html 

Does... 

I'm still digging through the ZSQL code looking for a way to fix this.
I'll let everyone know once I've figured it out.

Ok, here's a thought. What about trying:

  http://zope.kavi.com/comp_admin/contacts/mem/2/index_html

Since the 'mem' ZSQL Method is in your root folder, it will be acquired
by all folders below the root folder. Thus, the URL above should tell
ZPublisher to go to the /comp_admin/contacts folder, then call the
acquired 'mem' ZSQL method, with 2 as an argument, and using index_html to
display the results. (Assuming the parameter name is not required, because
you have checked 'Allow direct traversal', as you described.)

I am curious to know what the 'Allow direct traversal' button does on the
Advanced tab. Can anyone else here comment on that? Frankly, I didn't know
it existed, as I've been able to use direct traversal just fine without
it. It's curious to me that it changes the behavior of the traversal in
the manner you demonstrated. I'm dying to know why. :^)

In this case, I would probably do:

  http://localhost/events/modify_event/dbFindEventById/
         event_id/2/edit_event_details_html

(should all be one line)

Hey folks,
Boy I'm feeling mighty dumb, but I just now, after maybe 8 hours of 
zope stuff (late night after work), discovered where the tracebacks were 
hiding from me.  I searched this list, but never actually saw where they 
were printed, I finally saw it in the Trinkets Tutorial which I'm sure I read 
earlier <sigh>.  So just in case someone else is out there in the same 
boat as I was - the tracebacks are comments in the html error page. 
DOH!

You'll want to check out the doc/WEBSERVER.txt file under your Zope
directory. Make sure your running a recent enough version of Apache
and have mod_rewrite installed. Then, you need to configure rewrite
rules so that Apache will pass authentication info through to Zope.

Simon,
AFAIK, all the EFNet servers require identd.  If you are running ip-masq 
then you need midentd.  You can find it at rpmfind website 
( http://rpmfind.net/RPM )

Sorry, my mistake, there isn't an rpm for midentd... here's the url

Heck, identd is a trivial enough protocol. You can always just
write one in 2 lines of python which just returns "sod off" as the 
username. :)

That EFnet require it is somewhat puzzling.

Subject: [Zope] Zope install help needed: "Premature end of script header"
Message-ID: <v04011701b3179cd6f425@[204.244.68.39]>

I installed the  Zope binary on a linux box, and everything went well. User
authentication worked successfully with Apache using the 'REMOTE USER'
environment variable. Then I tried to get ZMySQLDA to work, but I couldn't
get the Zope Python install to find 'libmysqlclient'. I got a build of
Python 1.5.1 to successfully import MySQL.

So I decided to reinstall Zope from source, so that I could use my own
Python. The source Zope built okay, but when I tried to start Zope through
the web browser I got an "Internal Server Error" message from Apache, the
error log said I had a "Premature end of script header". I've checked
permission on the var dir and user authentication still seems to work fine.
I couldn't figure out why I was getting the error, so I tried re-installing
the binary distribution of Zope. No luck there either, I get the same
"premature end of script header" error message. I've checked the Zope.cgi
file, and it seems o.k.

Does anyone have any idea why Zope.cgi is failing on me? Is there something
I have to do to Apache or Zope if I've removed the Zope folder and then
untarred and re-installed a new Zope?

Don't know if this'll help, but this is what I get when I run Zope.cgi from
the command line:

Many thanks Pavlos - I saw that the Doc effort had moved to zdp.zope.org and
is using structured text, and thought that it was a bit of an opportunity
lost (no disrespect to the Zope Doc Effort of course) as I was amazed to see
that the FAQ system you wrote was XML-based and hence easily extensible.

Thats excellent! - thanks a lot. I'll be snooping around later on once I get
into work - I had looked at XMLConfig almost straight away, but had to put
it to one side whilst I got to grips with Zope  (and Python!) fundamentals.

At least I've got somewhere to start from now...

again many thanks for this,

Also, and this is important!

Don't forget to make sure that the cgi driectory holding Zope.cgi has
ExecCGI turned on.

As I said this is important, later versions of Apache don't turn it on by
default.

The error you get when running Zope.cgi from the command line is a red
herring, ignore it?

It comes about because SCRIPT_NAME is set by the Web Server and as you
aren't running it through such, you will get errors telling you that various
ENVVARS do not exist.

As to your other problem, hmm, it still sounds as if the var dir is not set
correctly, maybe?

Hi everybody,

I am in a FAQish problem. I am using ZopeHTTPServer for setting up a
complex intranet site. However, access control do not seem to work at
all.

Either I can build a public site (which is viewable by everybody), or
I have to use SuperUser passwd to enter in a private site.

I would like to allow user A to see folder X but not folder Y, and so
on. I have created users, assigned roles, but it seems not to work.

BTW, cut & paste do not seem to work at all.

Any suggestions ?

Thanks.

Subject: [Zope] Security tab in home grown Product
Message-ID: <Pine.LNX.3.95.990319091005.28046A-100000@animal.blarg.net>

I'm resending this to the zope list, because I didn't get any response
from the zope-dev list.

Hi.

I have made my first Product (a little message wall that people can post
colored messages to), but I am having some trouble with the Security tab.
When I press the tab, I get a Permissions screen that looks as it should,
but when I click the change button (no matter what permissions I change,
if any), I get the following error:

Sorry, an error occurred.

Traceback (innermost last):
  File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 877, in
publish_module
  File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 590, in

manage_changePermissions
    (Object: RoleManager)
  File /usr/local/zope/lib/python/AccessControl/Permission.py, line 166,
in setRoles
AttributeError: manage_main

I don't doubt that I am causing this, but since it isn't occuring in my
code, I don't know how to go about finding the source of the problem.

Thanks for any help you can give.

Subject: [Zope] frames and external method lookups
Message-ID: <9903190931.ZM14151@saab.coinet.com>

I have a DTML Document that references an External Method. This document
is embedded inside another DTML document. If I view this document, then
the page is rendered correctly. If I now take this document and reference
it from a <frame> tag, Zope complains and says it can't find the external
method. What's different here that causing me problems?

Here's some more details, including the traceback:

1. Zope-1.10.2-linux2-x86
2. The innermost DTML docuemnt (lighttablebar) refers to the extermal method
   like this:
	<!--#in expr="looprange(ltblSize)"-->
   'looprange' is my external method and is located in the top level folder
   'ltblSize' is a property of the document that "includes" this document.
   This innermost DTML docuemnt is also located in the top-level folder.
3. The next DTML document (lighttable_frame) includes the previous document
   with a simple #var command (in between some other html stuff):
	<!--#var lighttablebar-->
   This document has a property named 'ltblSize' defined as 6.
   This document lives two folders down from the top-level folder
   I can use the View tab in the manager to see the rendition of this page
   and it looks just fine and there are no complaints about looprange().
4. If I include the previous DTML document in another DTML document that
   is specifying some frames, e.g.:
	<html>
	<head>
	<title>Stock Book</title>
	</head>
	<frameset rows="60%,40%">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/lighttable_frame" name="ltable_win">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/navigate_frame" name="nav_win">
	</frameset>
	</html>
   When I use the View tab to see what this page looks like, I get the two
   frames, but in the lighttable_frame frame, I get an error message about
   looprange being undefined:
---- start of traceback message ----
The specified module, looprange, couldn't be opened.

Traceback (innermost last):

---- end of traceback message ----

So again, what is happening when the DTML doc is being refered to inside a
frame
that is different than not in a frame (and more to the point, how do I get
around this apparent problem)?

Zope (up to 1.10.x) expects every managed object to have a manage_main
method that provides the default management interface for the object.

You need to rename or create an alias from your default management
method to manage_main.

In Zope 1.10, there will be a new inherited method, manage_workspace, 
which should not be overridden, that picks the first item in you
manage_options as the default management interface.  This gives 
you more flexibility in naming and will allow more dynamic view
management.

Oh, I see.  So the manage_main I see is actually being acquired from the
folder my product instance is installed in?  If so that would explain why
adding things to it actually adds things to it's parent folder.

If I write a manage_main method, will it start magically working, or do I
need to add it to __init__.methods and/or one of the __ac_permissions__
tuples?

I apologize if for the off-topic nature of this post, but felt it was
too important to ignore.

Microsoft has released IE5, which is non-compliant with many of the
standards that Microsoft has helped author. As widespread compliance to
standards is one of the things that will greatly enhance Zopes success
in the marketplace (i.e. WebDAV, XML-RPC), I felt that this issue
deserved to be aired here too.

The original statement from the WSP can be found at:

Following is an email posted to another list I am on, as I think this
sums up the appropriate responses rather well.

Greetings!
  Since 1993 I've done my best to show everyone the good on the web and
to
help anyone who wanted it gain the knowledge they needed to create that
good.  Today I'm asking for your help.  I'm not asking not as Glenn
Davis,
CTO of Project Cool, and not as Glenn Davis, cofounder of The Web
Standards
Project.  I'm asking as Glenn Davis, a man who, for the past six years
has
worked to make the web a better place for everyone.
   Recently Microsoft released their 5.0 browser and after all this time
there is still not 100% support for the standards that make web
development
easier.  Standards that Microsoft helped create.
  Below are three simple letters.  Very to the point letters that ask
one
very simple question.  I'm hoping that you'll pick just one of those
letters and use it to ask Microsoft the very simple question within.  If
you would copy just one of those letters into an email and send that
email
to wasp@microsoft.com I would very much appreciate it.  This email
address
is one that Microsoft set up for email about standards.  I'm also asking
that you pass this email along to anyone else who has ever tried to make
a
webpage.
  My sincerest thanks for the help you provide.


Sincerely and simply,
Glenn Davis

Subject: [Zope] Web Application Software
Message-ID: <36F2C006.9D7E89C9@amvalue.com>

I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Ahh yes, Glenn "Master of Self-Promotion" Davis has found a cause with
which to attach his persona.  Glenn got his start at InfiNet, our former
majority owner.  I remember when he shared a 10x10 office with the other
Mac person there.

I love the "I'm not asking as Mr. Mega Big-wig, nor as My. Hyper Star,
I'm asking as a humble guy that singlehandedly saved the web" part.
That paragraph is so pathetic, I can't believe he actually wrote it.

IMO opinion, the only cause he is advancing is himself.  It's a shame,
because browser vendors _do_ need to be beaten into standards compliance
and away from bait-and-switch.

Ok, but what do you think of using the three templated emails? I feel

I believe the current agreement that Digital Creations has reached with
Sam Rushing (the author of Medusa) allows for open-source-style
distribution of ZServer so long as it's used with Zope.  Paul can
probably corret the exact legal situation, but basically DC bought an
unlimited license to give it away ... say thank you :-)

OK, I agree, and I ought to just focus on his words rather than on him.
Public retraction on the personal stuff, BUT I absolutely stand behind
taking offense at the words.  If you're going to lead an offensive based
on principal, make the self-aggrandizement a bit more subtle.

Hmm, didn't turn out to be much of a retraction. :^)

We reached a mutually agreeable arrangement whereby Medusa could become
the core for our object publishing system, under the Zope license.
Definately turned out to be a win-win-win (Sam, DC, and Zope).

AFAIK, ZServer was released (including Medusa) under the same license as
the rest of Zope. Which means that all of it is free software, including
the medusa code it contains.

Nope.

> 2) Is it purchased from Digital Creations?

Yes. At the moment, we are selling Collector. A number of
copies have been sold already. There are a couple of things
to note about a few of the packages that we have been
selling (relatively privately lately):

1) Most have little documentation (read the source Luke :-)

2) Our license specifically reserves the right to give the
software away at some future point (so you need to realize
you are paying to get it now, and shouldn't be annoyed
when/if others get it for free!)

3) Our license specifically prohibits redistribution, or the
creation of derivative works (for distribution)

4) We permit unlimited internal use of the code, including
operating public websites

5) We offer email-based support for 90 days (for 2 contacts
usually)

6) The license is for 5 developers only. If you have more,
you buy more copies

7) Additional support options are available for purchase.

The point of the above isn't to make a lot of money. We're
selling more copies than we anticipated, but hardly enough
to make this our business model. The point of charging is to
cover the inevitable support costs of shipping a product
that has little documentation, but is more technically
advanced to use than the content-oriented Zope general
release.

A secondary benefit is that people who purchase now are
clearly motivated to use the product(s). Therefore, the
support questions tend to be focused around real-world use
of the products, and help us make them more robust for the
inevitable Open Source release (whenever that might be).

So, which products are we currently offering for sale?

1) Collector
2) Z Tables
3) Z Network Client
4) Infoseek DA

In general, pricing is at $1,500 per package. The exception
in the above list is Collector, which is $2,000. The reason?
It makes heavy use of Z Tables, so essentially you are
getting two products for the price on 1.3333 products :-).

Those who wish to discuss this (either to become customers,
or to tell me that we're "off base") should write to me
directly, and _not_ post to the list.

I know that a number of people responded to this already,
including Paul. However, he didn't give as concrete response
as this direct question requests.

The answer is _yes_, Digital Creations most definitely paid
_real money_ to Sam for the right to embed parts of Medusa
in ZServer. However, the intent of the license is to allow
unlimited, free, Open Source(tm) use, within the Zope
environment. If you don't intend to use Zope, then you
should be licensing Medusa separately from Sam Rushing. We
highly recommend it (obviously), and have put our money
where our mouth is.

The reason that this is an important question to answer is
that we are so committed to the Open Source movement, that
not only do we release stuff that we wrote, but when
appropriate, we will invest hard cash to further the
community as well (ZServer being but one example).

<NOTE>I do not know much about btrieve.</NOTE>

<btrieve>
If you can make btrieve a data source you are home free. All you need is the
connector/drivers.

http://www.zope.org/Download/Adapters

Also look into:

http://www.python.org/download/Contributed.html#Database

Typically these modules make there way into zope as they are existing python
modules.
Actually I would gather that Btrieve has a c interface that would make a
great product.

</btrieve>

<dev>

As with all projects .... it depends.

Using attributes is the key to zope. If you take advantage of its ability to
store session variables Zope is far better than other solutions because you
do not need a database to store info during a transaction, you can simply
write it to an attribute in zope thus lowering the # database calls.

I guess the implementation depends on allot of variables that were not
listed in your email.

1. # of concurrent users
2. # of queries and "How databasy is the application? Big Queries?
OnChange?"
3. Specifics on your data model
4. # of tasks required
5. How OO(Object Oriented) are you?

It is a difficult concept to cover but developmental access to ZOPE is
remote by nature. Anything you can do in Zope is accessible anywhere, by
anyone else. Except for installing modules and products, you do not need
machine access ---> Everything is done online and inside of Zope. It is
convenient that way.

Look into the bug collector for the ZOPE site. It allows many levels of
access to the bug database except there is not database just Ztables. It
might be just the ticket.
http://www.zope.org/Collector

Also take a look at the example folder here 
http://www.zope.org/Download/Contrib
Specifically the DTML EXAMPLE FOLDER --> IT WILL GIVE YOU LOTS O' CODE and
HINTS 
</dev>

Just think in OO and Zope will work.

Best of luck.

I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Subject: [Zope] Why do I have to reimport External Methods ?
Message-ID: <99032019551700.01550@alpha>

Hi all !


I am new to Zope, and I have a problem with External Methods.

Everytime I change the implementation of my file in Extensions/test.py I have
to reimport the External Method to see the changes.

What am I doing wrong ? I just want the changes I made to the source
code to be reflected when I reload a page !

I hope someone can explain what I am doing wrong here.

Maik Röder


Some more details:

I have a folder called

VMBI

and an external method

test

in it. Everything works just fine,  the

index_html

file has a call to the external method, which just prints "Hello World!"

 <!--#var test-->

So the following URL

http://localhost:9673/VMBI/test

prints

Hello World !

But when I change the original source code to print for example

Hello Zope !

Then upon reloading the web page 

http://localhost:9673/VMBI/test

there still is printed

Hello World !

What's going on here ?

You don't have to delete and recreate an External Method each time you
change it's file. But you do have to go back to its properties page and
hit the "Edit" button to reload its module (this is actually a nice
feature of python, being able to reload modules at run time).

> What am I doing wrong ? I just want the changes I made to the source

Well, it may be possible to stat the External Methods file each time its
used, and reload it if its changed (you'd have to store its last
modification time somewhere to compare against). This probably isn't done
for performance reasons. Perhaps it could be linked to the BOBO_DEBUG_MODE
environmental variable or something to address this issue.

Is there a similar way to reload code for a Product, or is the
shutdown/restart of Zope necessary?

If I do have to continue the shutdown/restart process, is there any way of
tuning PCGI so that it loads up faster?

Thanks.

But wouldn't that kill the Zope process instead of having it shut itself
down?  How gracefully does Zope exit when receiving a SIGTERM?

A simple way that works for me is, when debugging, have a normal cgi version
postfixed with -c and use that.  This brings me to another thing:  the default
zope distribution doesn't include ZCGI and friends, I assume because Zope
users supposedly have no interest in normal cgi.  I think it should be
included anyway, so that Full Zope is a superset of Only ZP/ZT.  That's more
intuitive, and then you don't have to download both if you want to use both :)
And ZCGI.py is only a small text file, after all.  And perhaps zope users are
interested in ZCGI after all, or does zope make assumptions about running
persistently (can't see how it could, without violating http's statelessness).

And as far as tuning pcgi: you could shorten pcgi_socket():delay
or the 2 second sleep() at the end of pcgiStartProc().  The first one could
probably be pretty safely shortened with the miniscule cost of a chance of a
few extra connect() calls, but the second one should probably stay the same,
although I'm not clear on its purpose (give time for the child to sort itself
out?).

Here's a random question: how come the win32 pcgiConnect uses CONNDELAY
(defined in pcgi.h as 1), while the unix version says int delay=1; ?

See, that's the problem with open source: all sorts of grubby randoms can go
rooting through your code :)

You may season to taste.  The 2 second pause seemed safe enough 
on most tested systems, since we're flying blind.  We've reserved
an extra header byte to designate out-of-band data that could be 
much smarter about how to handle this, eventually.

I don't have the code here, but it's probably trying to
avoid some problem that I encountered when it was 
missing <wink>.

Probably historical flotsam.  The win32 portion of pcgi is
almost a completely separate product and only coexists with
its Unix cousin by virtue of an overabundance of #ifdef 
clauses. 

I've mentioned this before, but it probably won't hurt to 
repeat.  I don't think the win32 version of pcgi as the best 
solution for this sort of thing.  It's mainly there to fill 
out a niche.  Process launch is more expensive under Windows 
than Unix, so the Medusa/ZServer approach is probably more 
sensible in that environment, where good performance is
desired.

I don't consider that a problem. ;-)

People have been asking for my Calendar tag product, so I've uploaded a

Have fun, and let me know what you think.  When I get a chance I'll

Hi!

I'm working on an intranet site (using Zope). Now I need to make the site searchable. Tried using htdig, but without luck (should it work with zopesites?). Now I wonder - is there a builtin feature in zope that can fix my problem, or are there other programs like htdig that works with zope? 

Help is much appreciated!

Subject: [Zope] one 'document' in many 'folders'
Message-ID: <199903221343.IAA17544@gem.lightlink.com>

As a demonstration project to try and get a client to go with Zope, 
I'm converting a newsfeed database that I had originally built using 
Perl.

The object of the game is to pull fresh articles from a Reuters 
server every two hours and put them in a bin. A human editor goes 
through the bin, culls and sorts the articles, edits where 
appropriate.

One article may appear in more than one section of the site. For 
example, an article titled "Zope Is Cool" might appear in the 
Python, Web Development, and Open Source sections. Each 
section has its own contents page.

This is where I get confused. My Perl application simply used the 
filesystem as a database, and generated three separate static 
copies of "Zope Is Cool", placing one in each of  three directories: 
/python, /web_development, and /open_source. I suspect there are 
much better ways to do it in Zope, but how do I organize things?

My naive idea is to make each article a Document, one of whose 
properties is a list (or dictionary) of categories in which it should be 
placed. Generating each section's contents page would then take 
some figuring out, and performance on doing the contents page 
would be a concern.

If there's a better way, I'd certainly appreciate hearing about it.

Signed,

Correct me if I'm wrong, but the only way I see to do this *inside*
the Zope application is to keep all your articles inside one folder
(pool) and have key documents in your tree structure which 
reference an article in the pool.

I don't know if problems appear when you establish an acyclic
directed graph structure in the object hierarchy itself (I asked
the question myself months ago without an answer).
I see no point why it shouldn't work, but it is not maintained 
by the application.

An interesting fact is that your object's properties vary when
accessed by different paths due to the acquisition structure.
An object inside Zope's database (again, correct me, if...)
doesn't know about its father. It only knows about its sons,
the aq_parent path is constructed on each access.

Would also like to hear more about this...

Check out the FAQ on http://zdp.zope.org  it has some information on how
to use the built-in searching capabilities :-)  It's not perfect, and
needs lots more work, but it's a start.

This application sounds similar to stuff that I (and others on this list are
trying to accomplish).

My immediate term solution is to make multiple copies of the article in the
ZDB. I agree that this is suboptimal.

Paul@DC has mentioned that they are working on a "Catalog" feature that they
would like to integrate with Zope. This feature will be *perfect* for this
application (and many others). Unfortunately, I don't think this is on the
very near term radar scope.

Depending on how far out Catalog is, and when I manage to finish off the
basic necessities for my sites, I was thinking of delving into Zope's btree
stuff and trying to put together some kind of search interface. Right now,
though, I've still got a bunch of work to do before I get to that point.

What a great mailing list! I posted my question, shovelled the 
driveway (Ithaca NY, 8" of heavy wet snow last night), had 
breakfast and an extra cup of coffee, then came back to my desk 
to find 2 good answers. Thanks Stefan and Kevin.

Well, on the one hand I'm pleased to hear that my question wasn't 
trivial. But I'm disappointed to hear that my problem is difficult.

I'm competing against Cold Fusion here, and the problem resolves 
itself pretty easily with linked tables. (At least until I actually try to 
write the code.) So maybe I should just co-opt the competition and 
use ZSQL? But the odb is so nice, I really want to make it work 
that way.

I don't really need for the URLs to look like a directory structure:
instead of /open_source/zopeiscool, it would be okay for the article 
URL to be /zopeiscool?section=open_source. But that still leaves 
the problem of generating a contents page for each section. I 
suppose I could have a script that periodically-or-on-demand walks 
through the articles and generates a fresh static contents page for 
each section. Seems kind of non-zopish, but that might be the 
best way to get decent rendering performance on the contents 
page anyway. (The site is very active.)

>an acyclic directed graph structure in the object hierarchy itself

I suggest you try out your idea first. It sounds simple and
straightforward and performance won't be a problem unless you have too
many entries (but I am only guessing).

> some figuring out,

Assuming you have a folder Entries and folders Python and Zope. An entry
in the entries folder is a DTML doc with a lines property named sections
containing the sections (folder names) where the given entry belongs to.
In the root folder you have a DTML method like: (untested)

<H1><!--# var title--> contents:</H1>
<!--# with "_.namespace(section_title=_['title']"-->
<!--# in Entries-->
<!--# if "section_title in sections"-->
... Do something (ie link to the entry or render the entry etc ...
<!--# /if-->
<!--# /in-->
<!--# /with-->

you can call this method from inside the index_html method in each
section's folder.

This is great, I'm planning on doing exactly this myself. 

Roughly, if I don't want sluggish performance, what would the upper limit
be in regard to number of articles? Are we talking hundreds of articles?
Thousands?

Sorry to post a commercial plug here, but it seems in stride
with my post from this weekend to another question
(Collector).

Basically, Z Tables would be a pretty perfect fit (IMHO). I
realize that you too realize that (sort of), because you
suggested going the ZSQL route. Clearly, there are
similarities. But, Z Tables has already been independently
benchmarked as _kicking a**_ performance-wise, and is also
more closely aligned with the gestalt that you indicated you
liked about the object database.

Just a thought (and a few bucks, of course :-).

fields that I didn't use (the master and detail tables share some initial 
fields).  I took them out of the sql statement and the form, but I didn't 
remove them from the argument list.  (Just an FYI, the system allows 
you to add additional detail records, the first one is autogenerated from 
the master)

Unless you do something tricky, I doubt you will be able to get normal
search engines to work with a Zope site, since I belive that most search
engines want to read HTML files from the filesystem for indexing.

Right now there is a simple Find mechanism, but it isn't really a robust
search facility. In addition, Zope now includes low-level Python packages
for indexing. So the basic tools are there, but there isn't an easy to use,
out of the box search engine in Zope.

We're working on a much better solution to this problem. We're calling it
Zope Cataloging, and it is currently built with ZTables. I believe that
like ZTables, Zope Cataloging will eventually be free, and become a core
part of Zope. Unfortunately, I do not have a timeline. Sorry. :-(

As long as it's you (i.e. important cause of Zope's open sourcing)
posting commercial plugs on zope@zope.org, I doubt many people would
mind. :)

[ZTables]

Although I'm still a complete ZTables newbie, I've seen ZTables come up
repeatedly when there are similar design problems. This would indeed
seem to indicate ZTables are a good fit. :)

[Apologies if this post is considered off-topic on this list]

You might want to try Webinator, an outstanding search engine available at:

http://www.thunderstone.com/webinator/

It's free to use for up to 10,000 documents. It works by fetching documents
over HTTP (not your file system), so it should work with Zope. However, the
free version requires an Internet connection to check with the license
server, so it might be impractical for an intranet soluition without full
Internet access.


Hope That Helps,

I agree :-). Of course, this is precisely why we intend to
release it (eventually) as Open Source(tm). We truly feel
that the community will benefit, so we will release it. In
the meantime, we're swamped, and prioritizing workload based
on hard currency makes for simple decisions...

I just thought a little more about the approach having a pool
and some proxy objects that refer to the pool.

I think it could be made quite neat when using just the 
following code for the proxies (DTML documents):

    <!--#var "RESPONSE.redirect ('/pool/'+id())"-->

So you just need to put zope_is_cool inside your pool
and add DTML documents with the above code under
the same id to your folder structure wherever you like.
Just check it out.

Two caveats: 
- You have to use DTML documents, not methods, otherwise
  id() refers to the folder's id
- Make sure that zope_is_cool really exists inside your
  pool, or you get an infinite redirection!
  (zope_is_cool is not found in the pool and then sought for
  along the aquisiton path, which refers to zope_is_cool itself,
  which redirects to the pool which ...)

Maybe this could be even generalized to some kind of
"symbolic link" product. Ideas anyone?

An alternate solution could be something like <!--#var "_.getattr(pool,
id)"--> for your "link" methods. I think this would take better advantage of
acquisition. A document could pick up its headers and footers from the
category, instead of the pool. It does seem like someone could create a
"symlink" product pretty easily.

Subject: [Zope] Trying to understand the Scheduler
Message-ID: <36F69DC5.2FBB044@eq.uc.pt>

Zope is great. It's so great that I guess I'm trying to use it for doing
something different from what zope it's expected to do. I want to make
some SQL scripts to access different databases and collect the data in a
new table. That I can do with the following external method that calls
see_data and put_data ZSQLMethods

def get_data(self):
    result = self.see_data()
    self.put_data(value=result._data[0][1])
    return None  

Then I wish to make this kind of data management automatic every hour. I
dug in the sources and I found out the Scheduler class, which I think is
what I need (is it?). But I'm having some trouble using it. This was the
external method I tried (without success).

def eventGetData(self):
    rev = RegularEvent(get_data,(),interval=60)
    self.schedule(rev)
    return(None)      

It seems that RegularEvent is not available. Besides, is schedule
available trough acquisition in the folder? 

Can someone give me some light on this. I don't even know if it's
possible to use the Scheduler with external methods so it would be great
at least to know I'm in the right path.

Thanks

Looking for some enlightenment:
<set learning on>

I understand that Ztables was formerly Tabula an
object database.  

If one were starting from scratch without legacy data
would it make sense to use an object database instead
of a relational database?  

If so, is ZTables/Tabula a full, robust database
system that can scale up and exceed the
features of Oracle or SQLxxx databases?

What are the pros/cons of Object vs
Relational databases.

Currently it appears that Ztables/Tabula
is priced at $1,500 but eventually may become
open source.

From recent posts on the list

*"Make site searchable"
*"one 'document' in many 'folders'"

It seems like Ztables would be an Ideal 
solution to these problems.  ie, rather
than the kludge of multiple copies
of the SAME document, ONE copy in
the database.  Also, searching by
key or full text would be possible.

But for further enlightenment, can anyone
point to good examples on the web of the 
use of ZTables/Tabula?

woops, your request to <set learning off>

By nature anything named "tabula" wouldn't be a pure object database :-)
OODB don't have tables, tables are a relational concept, and I believe
ZTables is a relational database last I checked---b ut then I've never
seen it either, but the implications by Jim/Paul/et. al. are that it is
something along these lines.

> If one were starting from scratch without legacy data
> would it make sense to use an object database instead

Maybe, it all depends on your data, the interdependencies, and what kind
of queries you run, how ad-hoc, and what level of reporting tools you
need.  OODB are mature, but their supporting structure (reporting tools,
modeling tools, and more importantly Zen :-) are quite lacking in my
opinion).

> If so, is ZTables/Tabula a full, robust database

i doubt it, but then, Oracle/et al are not necessarily the right answer
for all problem sets, it's not a one hammer fits all nails solution.

> What are the pros/cons of Object vs
> Relational databases.

Dear gods, there's thousands of papers written on this topic ;-)
References are faster in OODB, ad-hoc is easier in RDB, and there are a
billion other blends... it's also necessasry to understand network
databases in my mind before you approach OODB.

You just can't generalize to this level, it's impossible, and a "quick"
overview of OODB v. Relational would require about 30 pages :-)

Subject: [Zope] passings vars to sql method
Message-ID: <36F6C357.1F277AE3@GestaltTechnology.com>

Zopists,

    I run into a problem. I have a DTML Methos that call an SQL Method.
The SQL method, displayTasks, has two parameters, userID and statusID.

The DTML method does have access to the variables userID and statusID
prior to calling the sql method with a <!--#in--> tag.

The DTML method looks like this:

<!--#var standard_html_header-->
<H2> <!--#var document_title--></H2>
<P><b><!--#in getUsers--><!--#var name--><!--#/in--></b></P>
List of tasks: <form action=displayUser method=post>

<SELECT NAME=statusID>
<!--#in listStatus-->
<OPTION VALUE=<!--#var statusID-->><!--#var keyword-->
<!--#/in-->
</SELECTED>
<input type=hidden name=userID value=<!--#var userID-->>
</form>
<table>
<!--#in displayTasks-->
<tr><td><!--#var taskID--></td><td><!--#var description--></td><!--#var
priority--><td><!--#var </td></tr>
<!--#/in-->
</table>
<!--#var standard_html_footer-->



THE SQL methos look like this:
select *
from task_schedule where
task_schedule.userID = <!--#sqlvar userID type=string--> AND
task_schedule.statusID = <!--#sqlvar statusID type=int-->

--------------------------------------------------
I basically can't run the query because it cannot get a value for userID
or statusID.
How do I pass these vars to the sql method from a dtml method???

Thanks in advance,

Freddy, did you make the variables you are passing to your SQL method
parameters of the SQL method?  If not they won't be looked up in the
request, they will only be searched via acquisition.

This is described in the Z SQL guide where it shows the order of lookup
for SQL method parameters.

Have fun!

The FAQ widget index_html DTML contains the line:

Without having yet looked at the source(*) could this be an error
occuring in Oracle itself?

I just noticed the ORA-* which is typically an Oracle error message.

  I have no problems with other applications as long as I stick with
 floats. Notably, Zope on Windows running through ODBC has no
 problems--the values are all converted to python L types. (Hey! maybe
 I should take a look at the ODBC code...) This is what originally led
 me to believe that the problem wasn't with Oracle, but within the OCI
 interface to Zope.  
  I also thought that it also might have something to do with my Linux
 install, but SQL*Net doesn't have problems and Zope works wonderfully
 except for long numbers.

 Environment info:
 Zope 1.10.2
 ZOracleDA 2.0.0
 RedHat Linux 5.2
 Oracle Net8 Client
 Apache

Message-ID: <004c01be74fe$35088aa0$0801a8c0@bobcat>

Ive started playing with DocTemplate for a project, but I will be
using it sans Zope.  I hope this is still the appropriate
place...

I want DocTemplate to expose an object model, and it seems
perfect for the task.  However, Im having trouble using "."
expressions.

Code speaks louder than words, so my code is:
##
class Spam:
	def eggs(self):
		return "Eggs"

spam=Spam()

from DocumentTemplate import *
ss=HTML('Eggs are <!--#var expr="spam.eggs()"-->')
print ss(spam=spam)

ss=String('Eggs are %(spam.eggs)s')
print ss(spam=spam)
##

What Im hoping to do should be quite obvious - I want to refer to
"spam.eggs" in the DTML.

With the HTML example, #var expr="spam.eggs()" is the best I can
get.  It seems ugly to me, and I feel there must be a better way.

Using the String example, I can't make _anything_ work.

Any I missing something?  Is there something I can do so that
String('Eggs are %(spam.eggs)s') does what I want?

Please CC me - Im not on the list (but did peruse the archives
before mailing...)

Thanks,

Mark.

Hi!

How come this code (from within index_html) doesn't show files and folders
within my folder?

<!--#tree branches="objectValues(['Folder', 'File'])"-->
<!--#var id-->
<!--#/tree--> 

(<!--#tree--> <!--#var id--> <!--#/tree-->) doesn't work either)

This is using Zope 1.10.2 on linux (2.0.35)

All I get is a blank screen - how come??

Here's an alternative that works:

from DocumentTemplate import HTML
class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()
print s.ss(s)

and a second choice:

from DocumentTemplate import HTML

class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()
print s.ss(s)

Thanks for the response.

My problem is that I want a deep object model.  I want the user
to be able to say "spam.eggs" or "pantry.eggs" etc.  Just using
eggs wont do - I really need it qualified.

The solution I came up with was:

class DotWrapper:
	def __init__(self, ob):
		self._obj_ = ob
	def __getattr__(self, attr):
		bits = string.split(attr, '.')
		ob = getattr(self._obj_, bits[0])
		for bit in bits[1:]:
			ob = getattr(ob, bit)
		return ob

Then:
 s=Spam()
 print s.ss(DotWrapper(s))

does pretty-much the right thing...

Thanks,

Mark.

	Small caveat: Since whitespaces could occur in an nested
attrbute
	access ("a.  b  .x") , it's better to string them first. An
alternative 
	approach for DotWrapper's __getattr__ could be (not tested):

	def __getattr__(self, attr):
	    bits = map (string.strip, string.split(attr, '.'))
	    return reduce (getattr, bits, self._obj)

If your search engine works via http it should work OK with Zope. 
Thunderstone Webinator (thunderstone.com) does this, and there's 
a free version that I think will do up to 10,000 docs. (The 
commercial version costs $700.) There's a command-line switch 
that tells Webinator to go ahead & index URLs that include /cgi-

We'll look at overhauling the install documentation for the next

Jeff,

I have cc'ed your question to the list, not to defer it, but to let you
pick the brains of several people who have tried, some successful, some
not, to run zope as a user in a web hosting environment.  None of us
here have tried it so we're not really the ones to ask.  It is true
there is no documentation on Zope with web hosting, perhaps your
discussion will provide information for the Zope Documentation Project,
AKA the Martijn Conspiracy.

As I understand it, the web hosting provider you pick is key to the
whole issue.  If they run the kind of environment that works with Zope,
great.  If they don't (and most probably don't by default) you must
communicate to them clearly what you want.  If they are cooperative and
cool, they will oblige you and join our Zope hosting family.  If you
can't get ahold of them and/or they don't care, your out of luck unless
you go with a Zope friendly provider of which there are two to be found
here.:

Hey Sture,
Check to see if your index_html is a DTML Document.  DTML 
Document has its own namespace and doesn't use the folder's.

If you change DTML Document to a DTML Method then you'll pick up 
the folder's files and folders.

My experience has been that if the hosting company is running Apache (many
do) and if they have mod_rewrite installed (which is probably also pretty
common), it is not *too* difficult to get Zope running in that environment.
However, many hosting companies have policies against creating long running
processes. Zope takes up a few MB of memory, which is considerably more than
an instance of Apache... so many providers are not keen on that kind of
thing. Before putting effort into trying to make Zope work in their
environment, you'll probably want to ask them if they are willing to let you
run a process that will hang out in memory all the time.

CodeIt (one of the Zope hosting companies, http://www.codeit.com) will
actually host Zope for you. You don't need to deal with building and
configuring the package at all.

This typr only affects meta-data seen by some Zope tools.

Nope, you aren't.

There is a similar change that needs to be made to *work around*
this problem.  In DCOracle/ociCurs.py, change:

            elif dbtype==2: # Number
                if scale:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

to:

            elif dbtype==2: # Number
                if scale or 1:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

This has the undesirable effect of causing all
numbers to be treated as ints. (This is what oracledb
does) :(  Unfortunately, you can't tell from Oracle column
meta data whether values in a column will fit into Python ints.

The right way to fix this is to implement Oracle's
NUMBER or VARNUM C data types and convert to Python
ints or longs on a case by case basis.

Right, but in this case, it's because DCOracle bound a buffer
that was too small to hold the values.

Again thanks for the Calendar tag.  I just ran across a php3 application
that might influence you/others.  It is http://screwdriver.net/twig/ 
The demo show you a live application and is quite cool

The <!--#var expr="spam.eggs()"--> is a perfectly valid way to do
it. Another way would be to use the "with" tag:

<!--#with spam-->
  <!--#var eggs-->
<!--#/with-->

Neither is really "more correct" than the other, though the with
construct is probably cleaner in situations where you use many
services of the object:

<!--#with spam-->
  <!--#var eggs-->
  <!--#var method_one-->
  <!--#var method_two-->
  <!--#var method_three-->
<!--#/with-->

Hmm - it appears that the expr support is currently broken
for the python string format syntax. We'll take a look at
that. You can, however, also use the with construct here too:

ss=String('eggs are %(with spam)[ %(eggs)s %(with)]')


Just in case you hadn't found them already, the latest DTML manuals
are on the zope site at: http://www.zope.org/Documentation/Guides/DTML.
They contain some examples that try to demonstrate common DTML idioms.

First, you should use branches_expr, instead of branches. And second, it
depends on what type of DTML object you have this code in. Is this code in
a DTML Method or a DTML Document? If it is a Document, you'll have to
specify the Folder you want the tree to start at::

<!--#tree expr="PARENTS[0]" branches_expr="objectValues(['Folder', 'File'])"-->
  <!--#var id-->
<!--#/tree-->

I think that your approach would work and have the drawbacks you suggest.
You could try it and see if performance is actually a problem.

Here are some other ideas.

First, you can put an object in many folders without creating
multiple copies.  You can't do this from DTML, but you *can*
do it from Python, and therefore, from an external method. 
This may be the simplest approach.

Second, you could come up with some sort of document management
system, based on clever indexing machinery, like ZTables or
on relational databases.  As someone else mentioned, Zope cataloging
with use ZTables to provide collections with advanced searching and
organizaing features.  This is still a work in progress, however.

You're wrong. ;)  There are a numnber of ways to solve this.  I suspect
the simplest is to simply put the same object in multiple folders.

(BTW, this is essentially the same thing as using Unix hard links.)

Sorry you didn't get an answer.  There is no problem with creating 
acyclic or cyclic graph constructors in the, uh, object hierarchy, 
which BTW, need not be a hierarchy. :)

Yes, exactly.  In fact, a better name for aq_parent might

Hello!

   I've finished large project using pure CGI concept (I used Neale's
html.py). Now I (and my boss) are thinking of switching to Zope, or at
least ZTemplates.

   While playing with Zope and SQL (I am using Postgres, hence ZPygres
Database Adapter), I found that Zope, when loaded into memory by Zope.cgi
(I am using Apache, and need to use in the future) opens a database
connection for every Folder where I created Connection object.
   It is bad, as I have many databases, so Zope eats up memory. Another
problem - what would do Zope if I restart Postgres (so all current
connections break)? Would Zope reestablish connections or just report
error?
   How could I limit number of connections Zope opens? How could I
define a timeout, after which Zope close a connection if there is no
activity between Zope and Postgres? and reestablish connection when
application ask for SQL data?

   With ZTemplates and CGI all these questions has one easy (but not so
nice) answer - there is no constant connection, a connection established on
every CGI invocation.

PS. BTW, I wrote short introduction to Zope in Russian:
http://sun.med.ru/~phd/Russian/Zope/
   Any Russian here to verify my understanding of Zope?

As I understand it, you should just create one Connection object in your 
root folder.  Then all the folders underneath the root folder have access 
to that same Connection object.

Ahh, no need.  Just put one Database Connection object in the top folder
and all the subfolders will "acquire" it.  That is, any SQL Method
defined lower down can use it.

It should re-establish the connection.  If it doesn't then there's a
bug.  This works fine with all the Database Adapters I've used.

There is one connection per Database Connection object.

Hmm, this is quite a hard thing to do, unfortunately.

Of course this means the CPU gets a tremendous beating on every request
and the response time goes down.

   There are connections to different databases. So you said "one
connection to one database"?

   I'll retest, but currently, when I ask ZPygresDA to close connection,
Zope reports "the site has technical difficulties" when I'm trying to
access the application.

Not too long ago I experimented a little with cyclic structures
inside Zope's database. One thing I noticed was, that the copy
support failed with tracebacks like this:

Traceback (innermost last):
  File D:\Programme\zope\koelnzope\lib\python\ZPublisher\Publish.py,
line 877, in publish_module
  File D:\Programme\zope\koelnzope\lib\python\ZPublisher\Publish.py,

ExportError: Object 184337 references itself

This led me to the conclusion to better leave my hands
off non-hierarchic data structures which differ from those
created by the management interface itself.

	>> Would also like to hear more about this...
	> Like what? :)

More or less simple answers like "this is ok and this
is not", or "you can store any complex Python data
structure inside the DB, but in conjunction with the
management interface, you get the following drawbacks.."

I'm still a quite unclear about the object management
in the database itself and the management layer Zope
adds. 
But maybe I just have to read the docs harder ;-)

If you can use one connection string in Postgres to access multiple
databases, then you just need one Database Connection.  Otherwise,
you'll need one connection per database.  Note that I don't mean per
table -- I don't know much about Postgres and don't know if it organizes
tables into separate databases that are selected with a "use database"
command.

Right, which is the correct behavior, as you had disconnected from the
database.  I thought your question was about restarting _Zope_, so I had
a misunderstanding.

I don't know anything about the Postgres client library and whether it
can reconnect to a server when the server is shutdown.  This definately
isn't a Zope issue though -- the client should handle it.

   No. Connection string include database name, so I need one connection
for every database.

   I meant 3 different situations:

1. I started Potsgres, then started Zope, then restarted Zope - Zope
reestablished connections. It's Ok.

2. I started Potsgres, then started Zope, then restarted Postgres. Zope
does not reestablish connections: This site is currently experiencing
technical difficulties...

3. I started Potsgres, then started Zope, then went to management screen
and explicitly close a connection. Zope does not reestablish connections.

   Situations 2 an3 could be resolved, if I go to management screes, close
and reopen database connections. But it is hard to remember "always restart
Zope if you restart Postgres"...

I'll admit that cyclic data structures are pretty rare, 
so handling them may not be totally correct in every case.

Export of objects partcipating in cycles is potentially, 
uh, confusing, unless the cycles are with objects that are totally
contained within the object being exported, although containment
is pretty hard to check.  I should probably take this error check out.

OK, but I need to know what "this" is.  I don't think
you want me to enumerate all possible "this"s. ;)

You can store any complex Python data in the DB subject to:

  - It must be picklable,

  - It must follow the persistence rules:
 
    - Root objects must be "persistent" meaning
      they subclass BoboPOS.Persistent (or implement
      an undocumented interface that BoboPOS.Persistent
      implements, sigh)

    - Subobjects of persistent objects must be "persistent" or
      they must be immutable, or be used immutably, as in:

         def add_member(self, member):
	      members=self.members

              # Oops, mutated a list
              members.append(member)

	      # OK, so pretend it's new and readd it
              self.members=members
         

> but in conjunction with the
> management interface, you get the following drawbacks.."

Basically, the objects need to implement certain
interfaces if they want to play in the management system.
If they don't want to play, they have alot of freedom.

We need to do a much better job of documenting these interfaces.
 
> I'm still a quite unclear about the object management
> in the database itself

The object management at the database level tries to be as 
transparent as possible.  The wish is that you don't have to
think about it.  Basically, if you follow the rules above, 
you should be OK.  

Probably the biggest pitfall in the database is the inability
to get to database objects when their classes can no longer be 
imported, because classes or modules have been moved or deleted
or because errors have been introducted into the module source.
We need to figure out ways to make these problems easier to
diagnose.

Maybe you just need to read my mind better. ;)

Ok, so we don't have a problem here :-)

I agree that if a remote cause forces a database connection to close, it
should attempt to re-open it... that should be optional of-course, but
should be the default.

Nope, you closed the connection, you have to open it.  This I agree is
the appropriate way to behave.

   Yes, I think Zope must reopen connection.

   May be...

   Well, what about such situation:

4. I started Potsgres, then started Zope, then worked with my application
and Postgres failed (postgres fails sometimes). Postgres returned an error
and closed connection. Zope, I think, should reopen the connection back,
but will it?

Well, actually it should be the job of the DA, not Zope.  It's not
spelled out in a standard anywhere, which probably should be solved.
More documentation probably :/  But hey, someone's gotta know what the
DA is really supposed to do, other than looking at an existing one.

Don't honestly know if it WILL, but it seems reasonable that it should
be capable of trying at the very least.  Again, this is the
responsibility fo the DA, not Zope... that should be made clear.  You're
using a 3rd party DA, so you might want to talk to them about it as
well.

So class Persistent's __setattr__ is basically also the level
that transaction and undo support work on? 
Can I expect the undo support to work if I take care of the
persistence rules, regardless of cyclic and acyclic structures?

Propably about time to switch to Zope-dev...

Pedro - 
If you need to do periodic tasks, the wisdom of the list says go with a
cron job script attaching to your Zopesite via the ZClient interfaces
(caveat: I know nothing about this - just repeating what I've read here)
Anyone know were to look for info on this elusive ZClient stuff?

Read the source luke :-)  

Actually here's where to find the basics of what you're interested in...

	.../lib/python/ZPublisher/Client.py

This should probably go into the FAQ in the ZDP PDQ ;-)  I remember
seeing a few examples of it, for the the life of me, I can't find them!

Subject: [Zope] Using database-connection from external methods
Message-ID: <19990323200153.C251@RaVER.duck.org>

Hi!

This will hopefulle be my last questions in a while...

Is there some way I can reach/use ZMySQL connection method from within an
external method? Rephrase - I have a connection established within Zope - I
want to call an external method that handles some sql-queries - is this
possible, or should I still have the external method handle it's own
connection?

Can external methods set/send back variables to the calling document/method?

Another question while I'm at it - is the DateTime module in 1.10.2 broke in
some way? (I get an error if I try to make a new property with the date type
set)

Help is much appreciated

(snip)

The next release of Zope will have a 'utilities' directory
in the distribution that has a load_site.py utility that 
demonstrates use of ZClient (aka ZPublisher.Client).

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

After reading Jim's mail I turned myself to the cron. I had already
written a simple script to http-call a DTMLDocument that calls my
external method. It works, but now that you told me about ZClient I see
I could have saved some time with just a single command

ZClient.py [-u username:password] url [name=value ...]

Thanks guys

Connection strings for MySQL also require you to include the database, but
you can still change databases at runtime via the 'use <database>'
command.

Subject: [Zope] Zope Database in XML
Message-ID: <36F7EF09.6AD34A99@digicool.com>

A side project of mine is to allow conversion to and from
Zope databases (and export files) and XML.  This will allow
people to more easily access their data without Zope and correct
problems, such as moved or renamed software modules, that prevent
data from being unpicklable.

I've completed a first cut at a tool for converting a Zope 
database to XML format. It is provided in the file 'bbb.py'
in a 'utilities' directory that will be included in the 
distribution directory of the next Zope release.

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

To run the tool, use:

  python utilities/bbb.py -rxml var/Data.bbb

For now, the tool provides a way to "get at"
your data without Zope and get a bit more of an idea
of how Zope organizes data in the database.

The file uses a module 'ppml.py' (Python
pickle markup language :) that must by in the
same directory as bbb.py or in the Python path.
ppml.py provides for conversion from Python pickles
to XML.  It will eventually provide conversion
from XML to Python pickles.  Comments from members
of the XML SIG (those who happen to spend time here
too) would be welcome.  I haven't written a formal DTD
for this XML format.  I would like to use a standard Python
XML pickle format, but I'm not sure if such a thing exists 
yet.

I took the approach of conversion to and from Python pickle
format for two reasons:

  - It allows me to do conversion to and from
    database format without actually creating any 
    (application objects).  This is much faster than
    creating actual objects and does not require that
    any application Python modules needed to unpickle 
    objects be around or working.  For example, this allows
    conversion of objects that are not unpicklable.

  - It means that many of the implementation details
    of pickling can be avoided.

Of course, in combination with the Python pickle modules, 
pickling objects to XML is straightforward:

  import pickle, ppml
  print ppml.ToXMLloads(pickle.dumps(myobject))

Enjoy.

Just have your external method call ZSQLMethods. For instance, I have an
external method which allows the user to upload a file to the database.
The external method reads the file, parses it, and calls a ZSQLMethod to
update the database.

To do this, assuming your ZSQLMethod is in the acquisition heirarchy,
simply call it like you would any other method. If you have a ZSQLMethod
called 'insert_client', which takes the arguments 'name, company, email',
just call it...

self.insert_client(name=client_name,company=company_name,email=client_email)

 
> Can external methods set/send back variables to the calling document/method?

External methods can modify the current REQUEST object that the DTML uses
from name resolution. If you are calling the external method from within
the DTML, just use 'self.REQUEST' to access the current REQUEST object.
Just create/set items on it like it was a dictionary... 

sekf.REQUEST['new_key'] = new_value

If you can access the database directly through this interface(xml/pickle),
couldn't you *potentially* map a network drive to the interface(cifs/nfs).
This could allow you to render data in and out of the database through the
file system interface rather than ftp/http.

Just a thought!

Alternatively your external method can return objects to the calling DTML.
for an external method spammethod you could do omething like:

class A:
	pass


def spammethod(self,n):
	a=[]
	for i in range(n):
		tmp=A()
		tmp.no=i
		a.append(tmp)
	return a

Then in your DTML you can do something like

<!--# in "spammethod(20)" sort=no -->
<!--# var no -->
<!--#/in-->

I'm not sure what you are getting at here.  You can export and import data to
a file system now, using the Zope database format, which is built on
Python's pickle format.  The XML conversion feature just gets the data into a
slightly more editable form.

One key difference between http/ftp and the file system is that
Zope trusts the file system much more and is willing to get pickles
(binary, XML, whatever) from it.  This is a sort of a security 
feature.  In the future, I'd like to make a variation on the
Python pickler that was easier to configure to be pickier and
safer to use with network supplied pickles.

Ok, I figured out a way to hack around this limitation of traversing an
ZSQLMethod. I whipped up a simple 'pluggable brain' for the ZSQLMethod in
question...

---------------------------------------------------
from Acquisition import Implicit
from Record import Record

class req_store_brain(Implicit):
    """ stores info from sql query in REQUEST """

    def __init__(self):
        new = {}
        for key in self.__record_schema__.keys():
            new[key] = getattr(self,key)
        self.aq_parent.REQUEST.other.update(new)
----------------------------------------------------

This simply sticks the results of the ZSQLMethod in the REQUEST object.
Everything in the heirarchy after this has access to the queries results.

What I am referring to is rendering objects in the ZOPE database to a file
system view. The object database could be managed as a Network Drive(except
that the view would be data in the ZOPE object database). You could through
some translation (xml or other) render the object database to CIFS/NFS.

1. Run applications directly from the ZOPE file system.
2. Modify and Render objects through a regular file explorer or file manager
potentially an external text editor or file editor(word,excel,other).
3. Objects that had no meaning to the file system view would not be
rendered. Attributes to file properties.

This is a feature of 8i that oracle is pushing. The rendering of a database
to a user that does not realize it is a database.

ie.
1. Open a spreadsheet in the Network Drive and see a current version of a
file and its data.
2. Intranet is now a shared drive - depending on your privileges - you see
different objects.

I guess what I am asking is: Can Zope act like a CIFS/NFS file
system(virtual file system) with a layer of translation for converting Zope
Objects to File system objects directly (XML or other)?

If I understand it, this is how the database is rendering objects to HTTP or
now(Zserver)FTP. Why can't you render them as a Network file system?

Any thought?

I've just hit something similar in the mysql client. The mysql client
has a time-out to close the connection with the server. I'm using it in
a test environment where it isn't accessed frequently. The connection is
automatically closed and I have to manually close and open the database
connection.

Has anyone already fixed it? Excuse me if it has already been asked in
the list, but the egroups site isn't working.

You seem to be asking for a hybrid of Zope and Samba ;-)  Seriously, we
have Samba, so one answer would be a filesystem driver for the undelying
OS that talks to the Zope server to get its information. This could be
re-exported as a samba share, or NFS or AFS or Coda or what-have-you. 
I've been musing about it for linux for a little bit - I'm going to try
and convince one of the bright sparks around here to take a crack at it.
For NT hosted Zope, you'd need to write an equivalent filesystem driver
- apparently the the SDK for that is ~$1000.

Oh, and parts of this are already present in the ZServer - it talks FTP,
and there was some discussion of exposing object properties as virtual
docs of some sort. Check the list archives.

Ah.  I think that this is one of the things that WebDAV is going to
accomplish.  For example, IE5 can create an thing that looks like

Subject: [Zope] Zope Database in XML
Message-ID: <57D47461794DD211825300A0C9D17EF906C8CB@IGOPDC01>

Ahhhh....

Oracle's approach to this is an add-on to 8i called IFS(Internet File
System). It renders a database to http(woo...woo, Zope does this in its
native functionality). Although, they are working on a renderer for native
file systems. This would enable object methods for making files on the fly.

As Zope already accomplishes this(rendering objects), thus presenting the
view of the oo database is thus a filter. HTTP,FTP,CIFS,NFS,POP,IMAP all are
protocols that speak the requesting clients language. Make Zope the engine
and supply a framework in Zserver to plug in the server renderer.

Samba is a great example. It renders between file systems quite well,
although it is rather a tough and complex animal and very specialized.
Although it would work along the same lines.

Actually, there is a PERL module to simulate file systems already. It could
be good start. Considering that most file viewing on Windows is moving to
HTML, the Network Drive is looking more and more like a simple security
login with a connection that is persistent, rather than actually mapping the
drive.

A distributed (native-CIFS/NFS) file system would change the industry.
Actually it already has (http) through a browser window. I am wondering when
it will occur as seamlessly as not having to be in a browser. If an ORB
existed that could render data to the requesting protocol, it would be a
great product, I think ZOPE could do this through the ZServer architecture.

The Server in this case is the renderer, the ORB is the fulfillment
component and the OO Database is the storage mechanism. The protocol plug-in
is stored in Zserver and renders the appropriate view of the data.

 PROTOCOL |    SERVER    |   ORB   |  OO DATABASE  |

</OS ADD-ON CLIENT> 
   HTTP   |    ZSERVER   |    --- ZOPE ---         |     Client dependencies
   FTP    |    ZSERVER   |    --- ZOPE ---         |     Applications
designed to be client/server!!!

   IMAP   |    ZSERVER   |    --- ZOPE ---         |
   POP    |    ZSERVER   |    --- ZOPE ---         |
</OS ADD-ON CLIENT> 

<OS NATIVE>   
   CIFS   |    ZSERVER   |    --- ZOPE ---         |     No Client
dependencies - Native Applications
   NFS    |    ZSERVER   |    --- ZOPE ---         |     CLIENT/SERVER
functionality yet no dependencies!
</OS NATIVE>                                             OS support is the
dependency!

If the rendering engine were modular, ZOPE would always be first in
delivering support for new protocols and client functionality(DAV
Support!!!), without changing the structure of the underlying database. The
data exchange between the ZSERVER AND ZOPE would have to be managed. "You
wouldn't want to serve a POP client an Excel file unless it is an attachment
just as you wouldn't want to render a query to a FILE SYSTEM accept ones
that have been designated as OK." Get It?

It would save the world a little time and effort if one system could render
data to a diverse set of clients. Rather than making a new server every time
a new client arrives. I could simply build a layer of translation(XML) for a
client and BINGO! New client/server.

At the Native OS level this has the most power. Rendering live data into an
Excel file on the fly is a real world application that would be a huge hit
right now. "I want this months sales report... open Sales.xls  BINGO!!! The
data is there." I would really like to edit html in Dreamweaver as I
regularly do and have it render into Zope. If you had file system level
support every known application could be stored inside of Zope or have
access to the data inside of ZOPE.

Here is the interesting one:

If you can have direct file access you could:

Open a client application out of an oo database that rendered a view of the
database back at you.

(Sounds awfully like an OS!!!)

Just Thoughts.....

You seem to be asking for a hybrid of Zope and Samba ;-)  Seriously, we
have Samba, so one answer would be a filesystem driver for the undelying
OS that talks to the Zope server to get its information. This could be
re-exported as a samba share, or NFS or AFS or Coda or what-have-you. 
I've been musing about it for linux for a little bit - I'm going to try
and convince one of the bright sparks around here to take a crack at it.
For NT hosted Zope, you'd need to write an equivalent filesystem driver
- apparently the the SDK for that is ~$1000.

Oh, and parts of this are already present in the ZServer - it talks FTP,
and there was some discussion of exposing object properties as virtual
docs of some sort. Check the list archives.

[Project Idea] Looking ahead to the future of Linux ...

[ I am on the Digest list, so send responses directly if you
  expect an immediate response. ]

Although I am a new user, I am quickly growing very fond of Zope.  Quite
amazing, multiplatform and all.  The option to use either the built-in DB or
an external one, the built-in web server or an external one.  My entire
company is thinking of standardizing on Zope since we run Solaris, Linux and
NT (along with a few, rogue *BSD variants) on our server-end.

Little and big internal projects aside, I was wondering if Zope could
possibly fill a gap that will come about with Linux shortly.  That gap is
software distribution at the enterprise server to client level.

Linux (and many other OpenSource software and systems) is winning in the
server arena, but the corporate desktop world is staying with NT and the
consumer world is staying 95/98.  While the third will take awhile, the
corporate desktop is something that is attainable in the next few years
(with all the Windows 2000 issues which I do not want to get into).
Microsoft has SMS for NT and even Apple has a better system for MacOS X
Server.  What does Linux have?

First off, most Linux distributions have RPM.  While the format is the same,
the filesystem and other distribution or installation-specific configuration
may differ.  Quite possibly, a Zope-based distributed management system
could be built to serve this purpose.

I guess my main question is if anyone else is trying to forge such a project
togther.  E.g., does the Caldera Open Administriative System (COAS) plan to
solve such software distribution issues?  If not, do any others?  If not,
I'd say it is a BIG DEAL to get such a project underway.  And Zope may be
the perfect fit for the back-end (hence, why I am posting this to this list
instead of a my local LUG).

Just an idea.  Please feel free to pick it apart (short of calling me an
idiot, well maybe you should anyway :-).  I am still learning Python at this
stage (big-time Perl advocate, but Python is definately better for
web-apps).

The field of online software distribution is certainly hot.  Marimba,
the original Java darling, has reinvented themselves in this field:

  http://www.marimba.com/products/products.htm

They are playing, though, in a pretty complicated mission-critical kind
of field.  The requirements are pretty daunting.

One thing I've seen that's pretty interesting in a low-tech kind of way
is rpmfind from rufus.w3.org from a repository.

It's certainly a big deal in that it is an enormous initiative.  Take
some time to jot down what you think the business goals and the
requirements of such a project might be and recruit some volunteers!

Beyond writing an ExternalMethod, is there a good way to catch exceptions?

For example, I have a database application that looks pretty ugly if
someone attempts to add a duplicate key to the database.  Ideally, I'd use
a <!--#try--><!--#/try--> tag to trap exceptions and to provide handlers
for them.

Anyone have any thoughts on this?

Message-ID: <8174B1EE3D2CD21180960000F8056723FCC3CE@telisnt1020.is.tel.co.jp>

 Thanks for the pointer!

 I have to retract what I said in a previous post about not having a
 problem with the ZODBCDA--it has the same problem. I had made a small
 hack of a product for my own study that connected through ODBC and
 that didn't have the problem because I used Python longs. I somehow
 got the two confused...

 This works, but everything gets converted to floats like you said. In
 my case, this is not so much a problem because I use a lot of large
 numbers but doesn't seem practical for general use.
 I found that if, in Buffer.c, I change lines 143 and 144 to

      case 'd':
         return PyLong_FromDouble(self->val.d[ii]);

 I can get the same results as my product--everything is a
 long. Unfortunately, this causes everything to be printed with
 Python's 'L' appended instead of '.0'. Either can be fixed by
 using fmt="%.f" to all of my number fields, but that seems like a 
 lot of extra work (maybe a quick hack to the Z Search Interface
 would do the trick?)

 Plus, what if I really have floats somewhere? Would something like:

      elif dbtype==2: # Number
         if scale:
            buf=Buffer(arraysize,'f')
            dbtype=4
            dbsize=8
         else:
            buf=Buffer(arraysize,'d')
            dbtype=4
            dbsize=8

 in ociCurs.py (lines 123-131) handle this? I haven't tested it yet on
 float fields. It might be better to just leave everything as floats.

I'm not sure I understand what you want here, but perhaps interesting
for you is the Trove project. Perhaps it's directed more to larger scale
internet based distribution, though. Another problem is that as far as I
know the project isn't progressing very quickly if at all (perhaps you
can help).

I've even heard mention of ZTrove, which would be a Zope based Trove, if
I understand well. I don't know what the status on that is.

Mind, I don't know a thing about Trove, just giving pointers in the hope
it's useful.

Hello

I try to set a variable to the current date with some formating:

This works:
<!--#call "REQUEST.set('MyDate1',ZopeTime)"-->

But how can I format the ZopeTime to get only the part I want.(month/year
for exemple:   fmt="%m/%Y")  ??

Trove is sketches of code in Python (written by Eric Raymond) and ZTrove
is vaporware, barely prototyped in bobo a few months ago when I was on
the Trove list.  It's unfortunate, since I felt that Trove was a great
idea; the Internet hasn't reached the point of 'we need it now' in order
to get some development behind it.  Personally, I think Sunsite and
RedHat should give us lots of money so we can write it. :)

With Ken and I now in the Zope loop (Ken was one of the original Trove
designers, and I was in on the GUI side of things, pushing what was at
the time Bobo) we could probably bang something out sometime in the far
future.  We'd prefer someone in the community start it up because Paul
and Rob have us booked sometime into the year 2011.

I just ran into some odd behavior with fsimport that may explain the 
problem that Milos posted last week.

On my Linux box, if fsdir == '/fred/barney', then fred as well as 
barney must be world-readable. If not, you get the error traceback 
Milos reported in his March 14 posting.

Oops, posted too fast. I should have said that fred must be world-

Confera uses ZTables functions, and these were introduced in Zope 1.10

...just download Zope 1.10.2 and Confera will work just fine.

Confera requires Zope 1.10.2 to run. SearchIndex is a package that is
oncluded in that release.

Zopists,

One special page has the following code the uses a 'with' tag to include

The parent object has the following permission settings:

That's just Unix-style permissions, no?  Can't expect to

Subject: [Zope] Counters
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC6F@peter.sths.org>

I remember noticing various comments on the list bemoaning the lack of
some sort of counter. I also remember noticing the objections which were
raised, and why counters weren't feasible. I don't remember reading
these objections, which may be why when I found a need for a counter, I
sat down and wrote one. I now have a working Counter product which
provides a <!--#counter--><!--#/counter--> tag .

It includes the ability to have multiple non-incrementing displays of a
counter, and the optional ability to render the individual digits using
a supplied template, thus allowing graphical counters of whatever sort
you feel like using. The counter uses a long property in the containing
folder, so you can manually set the counter to whatever you want. 

It also provides the optional capacity to have a short 'memory' of
recent IP's, preventing the 'running up' of the counter by scripts or
massive reloading (well, makes it more difficult anyhow). 

The template is supplied with variables which indicate the position of a
given digit in the list (it is wierd, it works from back to front, since
it uses modulus) including whether the particular digit is the first,
etc. 

If someone will supply me with instructions on how to package the
product, and how to upload it, I will be happy to make it available.

Thanks are due to tsarna@endicor.com, on whose product this was based,
and to Jim Fulton and Philip Aylesworth for answering my questions.

Uh, no, I think. chown root /fred, chmod 700 /fred, chmod 711 
/fred/barney. Then anybody can get a listing of barney, but only 
root can see what's in fred. And if I su nobody and run python, 
os.listdir('/fred/barney') works but os.listdir('/fred') gets 'Permission 
Denied'.

With regard to the IP checking mechanism. Realize that this reduces the
count for machines behind a masquerading firewall and increases the
count for machines on dynamic IP dialup accounts. 

If anyone is interested in using this counter but wants to prevent a
given IP from incrementing the counter a second time under any
circumstances, it should not be too hard to modify the code to store the
IPs in an SQL table as (I think) Slashdot does. I have no need for this,
and don't intend to code it, but the code, being Python, is, I think,
clear enough to modify.

I'll indicate my appreciation of your contribution by, well, asking for
more! :^)

One of the big objections of the counter kind of object is that the
object database gets bigger on every request.  A good workaround for
this would be to cache writes to the database.

Thus, imagine a counter that:

1) Only wrote to the database after a threshold had passed.  For
instance, only every tenth state change or not until ten minutes had
elapsed since the last write.

2) If the process was nicely shut down, the object would save itself.

3) Had knobs in the management screen that allowed adjusting the
"buffered write" policy.

The benefits:

1) The database wouldn't keep versioning into oblivion.

2) The application wouldn't be slowed by writes on every request.

The drawbacks:

1) If the process exited not nicely, some state changes would be lost.

The counter ought to place the properties in the Document if it is a
Document and not a Method. If anyone can contribute code which will take
'md' and return x, where x is either the Document or the Folder
containing a Method, I would appreciate it.

Would Zope run on a win3.1 laptop the same as Win95?  Anyone doing this?

I'm currently running Zope on Win95 desktop without problems.

Subject: [Zope] Longs on the Property page
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC72@peter.sths.org>

In the stock Zope 1.10.2 distro, putting a Long in a property causes a
curious error to manifest. When the property page is displayed, the long
is display like 44353L. If the then change any other property and
attempt to save changes, you get a traceback saying that the property
for the long is invalid. You are forced to manually remove the 'L'
before saving changes. 

May I suggest that when the properties are display, if the type is
'long' then the display code
should do something like this:
str(long_value)[:-1]

This would remove the L before it was ever displayed.... Alternatively,
something in the response code needs to be modified to accept an 'L' at
the end of an integer destined for a property whose type is 'L'.

Subject: [Zope] The best way to pack and close PickleDictionary?
Message-ID: <19990324200904.8613.rocketmail@web204.mail.yahoo.com>

Previously, using Bobo, I created several PickleDictionaries for use on
my website. Regularly, I would pack these databases before ending the
CGI call since they were altered very frequently.

Now, using Zope, I find that I cannot pack them without receiving error
messages telling me I'm attempting to write while the database is in
read-only mode (it appears the Zope threads out the packing). I also
found that Zope caches these databases and issues an error when I
attempt to open them again.

What is the best way to pack and close these databases? How can I query
which db's have been opened? Even if I do keep a mapping of previously
opened db's, how can I find out if Zope is closing them. 

Any help is appreciated. 

Thanks,
Kevin

Hey.. this isn't bad.. in writing even :)

Okay, I have a prototype of this written.. basically you can do the
following:

<!--#try-->
foo
bnar
<!--#var sgkjgdsjksdg-->

<!--#except-->

The exception was <!--#var err-->

<!--#/try-->

So, if an error occurs inside the first block, the second block is
rendered with err substituted for the variable (in this case it prints
exceptions.KeyError

This is pretty basic stuff, so I'm looking for ideas on where to take
this.

Anyone have more ideas?

This is just a guess, but I doubt it.  You'd probably need a DOS port of
Python, which would eliminate all the networking code.  This is just me,
I don't have a 3.1 box, but... you're welcome to try :-)

Goodie goodie :-)

Message-ID: <613145F79272D211914B0020AFF640190D9F66@gandalf.digicool.com>

I've gotten a lot of reports about a broken link to the ephemeral,
much-referenced "BoboPOS3a1" technical docs.  I promised myself I
wouldn't update the link unless I updated Jim's doc to Zope-ify it.

Thus:

1) The official name of the database is "ZODB", the Z Object Database.

2) The News on the site has a link to the ZODB3 Technical Documentation.
This is a very well written, circa October document from Jim Fulton that
describes the architecture of the next version of the database (i.e.
Zope2).  It's quite nice -- contains UML diagrams, API discussions, etc.

3) The broken links have been updated.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC79@peter.sths.org>

Ok, having read the newly available ZODB manual, it seems that I should
override __setstate__ and call the old __setstate__, passing it a
dictionary containing only those attributes I wish to be persistent.
Then I don't have to call my __setstate__... it will be called
automatically by the system. This should have the effect of making any
item not mentioned in my dictionary non-persistent, which will allow me
to accomplish Paul's goal. Now, the BIG question... This ZODB manual is
for ZODB3, which we don't yet have! So is this still the correct and
workable technique for accomplishing this?

Thanks again... and please everyone, don't use the old Counter product,
since these tags are going to conflict horribly, and this new product
should be much better for the DB, according to Paul, if I can make it
work.

For .deb there is the official package manager (www.debian.org), but
there's a 'Debian Package Finder', which is already complete python :-)
On http://badger.alaska.net/debian/finder.cgi
That may be easier to convert to Zope.

Well - darn if you aren't right.  Only the
immediate parent directory of the item to

Maybe something like this for the version 2.3 :-)

Here is the updated Counter Product. This contains two classes, one
which provides a visible Counter Product which can be added as an
object, and which has Security options, and a new tag which provides a
means of accessing the Counter Product. Note: the tag should be able to
access ANY object which possesses a getCount() and a incrementCount(md)
where md==_. So an SQLCounter Product which stores its numbers in an SQL
database should be able to use the same tag structure. Since it passes
md into the incrementCount, the Product is free to store as much or as
little of the REQUEST as it chooses. My product stores only the IP
address, and only under proper conditions.

The tag structure is described in the CounterTag.py source file, and
examples are given.

I hope this is useful to someone.

 This is the try block
 <!--#raise type="bar"-->
  You suck
 <!--#/raise-->
<!--#except-->
 There was an exception! Yay!
 <p>It was <!--#var errname-->
 <p>It has this to say: <!--#var errmsg-->
<!--#/try-->

I incorporated a suggestion that except should handle <!--#except
NameError--> to specify the error to trap.  Also, <!--#except--> will
handle any errors by default.

This is packaged as a product, is this the best way to distribute this??

Grab it from:
ftp://ftp.spyderlab.com:/pub/zope/Try-0.1.0.tar.gz

Since I've only been programming Python on and off, hopefully I didn't
make any major assumptions about doing things a certain way.  Please let
me know if I have.

There is another IRC channel on the EFNET network, #zope.

It is 'protected' by an eggdrop bot so there should be little chance of the
channel disappearing.

It is manned, at the moment at least by, Phil Harris, Fredy Villa and
others.

There is also a knowledge bot, zoppy, which can answer rudimentary questions
about Zope/Apache/Python.

We have a small but growing community, join us.

See ya there

If I have a URL like '/manny/moe/jack', I know that from within the 
top-level object, I can retrieve the object 'jack' as 'manny.moe.jack'.

But if the context is jack, how do I specify the top level so I can 
talk about manny?

The top-level object is the 'app' attribute in the Main
module.  Note, however, that this will change in
ZODB3.

  import Main
  Main.app.manny

From an external method, self is the object the Externel Method is called
from. If you have REQUEST passed in, you can access PARENTS[0], which is
the top object. From there you can traverse down the hierarchy.

Message-ID: <Pine.GSO.4.02.9903250839420.15119-100000@isis.visi.com>

Okay, I understand that the "fall-through" authentication to Zope will not
work with rewrite rules when Apache 1.2.6 is used.  Unfortunately the
project I'm starting is being done for a shop that refuses to upgrade to
1.2.6.

I have Zope working just fine with Apache authentication; for the needs of
my project, this method of authentication works just fine.  However, I
need to know how to properly set up Zope to run in a virtual domain
"container", _and_ to only authenticate parts of the object hierarchy at
one time.

The idea is that we have a website

docs.foobar.net

that is a virtual domain on an Apache 1.2.6 server, and we need to
authenticate any requests underneath

docs.foobar.net/manage

so that the world can see the pages but only people in our list can
manage.

Another simultaneous difficulty is finding the proper way to make this
virtual domain automatically start in folder "docs" of Zope's object
hierarchy.  I've used an Alias to translate docs.foobar.net to
docs.foobar.net/cgi-bin/Zope.cgi/docs , and it works fine, but I don't
have proper Zen mystical knowledge of Zope to understand the _proper_ ways
of doing these things, if such ways exist.

I have done a scan of Email archives and most of the documentation on the
Zope site, but either I'm dumb as nails or just don't know the proper
magic keywords to get the information I need.

Zope looks great, I've resisted learning a new language but a killer app
makes it worthwhile.

I am not sure how to classify it. The original complaint was about the
Properties page. 

My problem seems to be with values returned from MySQL - even regular
integers get an L tacked on the end (This didn't happen with zope 1.9).

So is this two seperate collector entries?

Where does mine go - Zope, ZSQL Methods, or ZMySQLDA? What do others
think? Has this shown up with other SQL DBMSes?

One thing I just thought of: I moved my ZMySQLDA over from 1.9 to 1.10.2
without recompiling it. That is when I noticed this problem. Whould
something have  changed in the python header files or something that
would have made it advisable to recompile ZMySQLDA? What did others do?

Phil.

Subject: [Zope] The Artist Formerly Known as NotMail
Message-ID: <613145F79272D211914B0020AFF6401907BBB6@gandalf.digicool.com>

Greetings,

For those of you interested in the NotMail project we have some
announcements.

First, Digital Creations has officialy adopted NotMail as one of it's
products.

Second, in an attempt to make the products at least *sound* more mature
:), we are changing the name.

Third, in the last two weeks I have been working pretty hevily on
NotMail and it has changed significantly.

Therefore:

NotMail is, for the interum, called The Artist Formerly Known as NotMail
(TAFKAN).  We still call it NotMail, but that's just our code word.

TAFKAN was once a product, but now it's just a bunch of dtml methods.
The actuall imap functionality that TAFKAN needs has been abstracted
into another product called IMAPAdapter.

IMAPAdapter is very early alpha software.  It has several known bugs,
and Linus knows how many unknown ones.  Your millage may vary.  It may
light your computer on fire.  It might delete all your mail and crash
your imap server.  It might send insults in your general direction.  You
get the point.

IMAPAdapter is, in Zopespeak, a 'user database'.  Other examples of user
databases are User Folder, UserDb Folders, and etcUserFolders.
IMAPAdapter walks, swims, and quacks (to quote Jim) like any other type
of user database.  The simplest example of using IMAPAdapter is:

Create an empty folder without an 'acl_users'

Add an IMAPAdapter (it will automagicly call itself 'acl_users'),
telling it where to find it's imap server, what default roles to assign
to users, and other misc stuff.

Create a DTML Method called index_html containing the following DTML:

    <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

Going to this file will prompt you for a username and password (assuming
you've correctly set the permissions and roles).  The username and
password you enter here must be a valid IMAP login for your imap server.
It is *not* necessary to add a Zope user to Zope, IMAPAdapter will try
your uid:pwd pair against the IMAP server and validate/deny you based on
the sucess or failure of making an IMAP connection.

What you will see when you look at this DTML Method is a pretty #tree
breakdown of all your imap namespaces, folders and subfolders.

IMAPAdapter, like all other user databases, contains a validate() method
that Zope calls to authenticate a user.  This method returns an imapUser
object (which inherits BasicUser, like most other Zope user objects).
This user object is what AUTHENTICATED_USER refers to.  imapUser exposes
the imap API to the DTML programmer.  The API is currently a very rough
draft, and there are several functions that were in TAFKAN that are
missing in IMAPAdapter (like the folder management stuff to
add/edit/delete imap folders)  At the moment, IMAPAdapter is pretty much
read-only on your 'imap space'.

Voila!

IMAPAdapter is available in public CVS.

Web CVS access will be here soon!  (yippee!)

I have a Zope sandbox which I would like to use to play with new features 
as they become available.   Unfortunately, for the past several days my 
sandbox server has been broken because ExtensionClass/ComputedAttribute.c 
is missing.

Is it missing on purpose?  If so, is there  a way I can work around it?

Hello,

I'm having a strange problem with logged in users getting to anonymous
areas of the site. Here's an simplified example to explain...

Two directories off the /
/private
/public

/private allows no access to "Anonymous User", requiring a login.

There are no usernames in /acl_users. All the user info for logging into
/private is kept in /private/acl_users. 

/public has no acl_users folder.

If you start up netscape, you can get to /public without any problems. But
once you've logged into /private, you can't get back to /public without
getting an unauthorized error...

  You are not authorized to access this resource. Username and password
  are not correct. 

  Traceback (innermost last):
    File lib/python/ZPublisher/Publish.py, line 877, in publish_module
    File lib/python/ZPublisher/Publish.py, line 531, in publish
      (Info: /MCExam)
    File lib/python/ZPublisher/Publish.py, line 297, in unauthorized
  Unauthorized: (see above)

Any tips about how to fix this. Note that the login info has to stay in
/private/acl_users (they can't be moved to /acl_users).

Thanks,

Ok, the problem was that I had the roles defined on the top level folder
and the users defined in the subfolder. By moving the roles into the
subfolder, the problem went away.

Thanks.  Yes, please go ahead and use this in the standard distribution

I suspect a matter of resolving.  Probably be a two step procedure, 1) try
to match the error by string exactly, otherwise 2) evaluate each handler 
in turn and see if the exception isa class.

I have fixed this in 0.1.1 of the Product which is now available from the
same directory as the original.  I've also made some other additional
fixes relating to the default error handler.

Here's the file:

Subject: [Zope] URL and #tree trouble...
Message-ID: <19990326081646.A10042@box.dust.za.net>

Hi!

A day or two since last question - now two new ones...

Q1

My site is organized so that one folder keeps several other files and folders (containing files and folders and so on). Something like:

Top [Folder]
	F1 [Folder]
	F2 [Folder]
		F2-file1
		F2-file2
		F2-folder1 [Folder]
		F2-folder2 [Folder]
			F2-folder2-file

...

index_html (Top) has <A HREF="F2">F2</A>
index_html (F2) has <A HREF="F2-folder1">F21</A> and <A HREF="Top">Top</A>

Starting at URL: localhost/Top is fine and following links to F2 and from there on to F2-folder is correct (URL beeing localhost/Tope/F2/F2-folder1), but if I, when in F2, press the link to 'Top' something strange? happens: I get to Top all rigth, but the URL is now localhost/Top/F2/Top (Top beeing appended to the URL)

What am I dooing wrong?

Q2

Recently I got help on using the #tree tag, and apparantly everything worked all rigth, but ...

I get the tree-view, can expand the tree pressing either foldernames or the '+' button - fine. But If I press the '+' button I'm not able top directly access the files appearing (404 error, file not found), I have to enter the folder first before I can get the file. This seems strange and I want to know if theres a solution to this.

Heres my #tree href part:

<A HREF="<!--#var URL1-->/<!--#var id-->"><!--#var id--></A>

Help is much appreciated

You're URL is a relative one. The browser sees 'Top', and requests the
object Top with the current Base URL, which is localhost/Top/F2/. And
because of Aquisition, Top.F2.Top exists.... And so will
Top.F2.Top.F2.Top.F2.... which can get you into a nice caching problem.

Your URL should include the realitve path to the subfolder. the var
tree-item-url gives you the URL to the current object, relative to the base
object.

Your code should read (untested):
<A HREF="<!--#var URL1-->/<!--#var tree-item-url-->"><!--#var id--></A>

Or words to that effect..

Hello.

   Continuing the subject...
   Next question. If Zope opens one connection to a database, how does Zope
manage concurrency?
   Currently, when two CGIs run in parallel, every CGI opens its own
connection to the database, lock neccessary tables, and Postgres manage
concurrency very good (even detecting deadlocks). Next Postgres version
(6,5) will have Multi-version Concurrency Control. But all this is for
different sessions. Zope opens only one session. Is it a problem with
concurrency?

Hi,

This is (I think) an unusual question on this thread, but I want to ask it.

We are at the start of making an intranet, which will contain a database of
procedures (how to handle some examinations etc). We want to make it able
that people can query this database and get the information they want on
there web-browser.

A day ago, we were confinced that PostgresSql with PHP3 (www.PHP3.org)
would be the solution to this problem. This on a RedHat Linux 5.2 system
with Apache as
web-server. But now we've seen Zope. I'm wondering..., can Zope do the same
things as PHP3? Or is this a complete different application? How stand Zope
and PHP3 next to each other?

I believe PHP3 is a scripting language... I'm wondering : is Zope also only
a scripting language? Or is it more? Is the scripting language (=Python?)
more powerfull then Zope)

Are there people, using PHP3 next to Zope? 

ps. Has Zope the capability to easely make these scripts? I mean not
text-based , but in a certain IDE or RAD application?

Please, say in some simple words what Zope is and for what it can be
used... I've read the web-page. But since I'm a stupid person in this field
of webservers I can't understand what they are explaining.

Thanks in advance.

Kind regards, Tom.

Subject: [Zope] Limitations of just using External Methods ?
Message-ID: <3.0.5.32.19990326185538.0093de20@mail.skinnyhippo.com>

Hi zoppelgangers,

I have several applications built 100% with python CGI
scripts that I'd like to run on Zope. The reason for 
this are :
a) For the better performance (I was worried about
   the scalability of CGI for high-availability and
   knew I had to move to FastCGI or the equivalent)
b) I really really like the way Zope takes care of
   the CGI variable handling (ie. declaring the 
   HTML form fields as arguments in the python method).

However, I don't really want to use DTML at all.
The reasons is that I find it much harder to read 
than pure Python. This is just a personal aesthetic 
thing and no criticism of Zope at all (full kudos to
Digicool on an excellent application). It's just
coding aesthetic : I like it all kept in Python, 
like servlets in java (as opposed to CFML, ASP etc).

So, I've put all of my CGI scripts in a newly-created
extensions directory and registered them via the 
Zope web-manager. It was, as the documentation says,
incredibly simple and it seems to work for simple
methods. (I'll declare my own packages later).

Now, if I just use External Methods like this (using my
own ex-CGI Python scripts to query databases, IMAP etc),
am I missing out on any of Zope's main benefits ? 
In particular, the cache management ?  
Would I have to turn my stuff into  a Zope Product to 
get these benefits ? (I've not had too much joy with
the Product stuff yet)

Message-ID: <000501be777e$83130900$147800a0@pc-pi0>

Hello,

I'm confused with external methods. Please help.

I want an external method to access its context (for the
purpose of acquisition, etc.). So I write:

def myExtMethod(self):
    pass

Within myExtMethod, I should be able to:
- write self.REQUEST to access the current REQUEST object (I
need to be able to modify the current REQUEST object with
self.REQUEST.set(...))
- or for example self.myzsqlmethod() to call a zsql method object,
right???

Let's suppose that myExtMethod is:

def myExtMethod(self):
    l=[]
    for i in self.l:
        l.append(i+1)
    self.REQUEST.set('l', l)

Now, how can I call this method from DTML?

<!--#var myExtMethod-->
<!--#var "myExtMethod()"-->
<!--#var "myExtMethod(this())"-->

All don't work. I end up in a traceback. "read only class, buffer"

Any hints?

Zope manages concurrency by being single-threaded... so only one query at a
time, on ANY connection...

Hi Jepthe,
First, if you want to acces the REQUEST object, you need 
to declare it as a formal parameter:

def myExtMethod(self, REQUEST): ...

REQUEST is then passed automatically by Zope's internal
magic, which looks up formal parameter names and matches
them to arguments from HTML forms, HTTP Headers, etc.

The "read only class, buffer" traceback is due to a very 
annoying bug in ExternalMethod.py and screws up any 
other error messages in external methods.

I can't remember exactly if it was in line 254 or 256 in
ExternalMethod.py, but here's the code I use to fix it:

ExternalMethod.py, from line 254

                if type(error_type) is type('') and lower(error_type) in
('redirect',):
                    raise error_type, error_value, tb
                if (type(error_value) is type('') and
                    regex.search('[a-zA-Z]>', error_value) > 0):
                    error_message=error_value
                else:
                    error_message=''

With that you should get better error messages.

Regards,
Stefan

PS:
	<!--#var myExtMethod-->
	<!--#var "myExtMethod()"-->
should be both OK

Tom,

There are probably other guys here that can give you a better comparison
between zope and php3. I never used php3 but I used ASP (the microsoft
stuff), which is similar (though worst than php3 :-).

With Zope you get a server markup language (called DTML) which you can
mix with HTML. This concept makes it even easier to program than mixing
a scripting language with HTML like php3 and asp do. From what you said
I guess you will just need this kind of programming... so Zope will be a
better choice than php3.

But with Zope you also get *the best* scripting language available:
Python. You can add logic to your application by writing external
methods or products. This kind of extension is much more powerful than
php3, although maybe a bit more complex.

Zope also has a great IDE for managing your site through the web. 

Although I cannot tell you which one is better, if you give Zope a run
try and, ... if my instinct is correct, you will want no other thing.

hope it helps,

I've used PHP3 since it was PHP/FI and done lots of work in it. It's 
database integration is excellent and the ability to include PHP3 
code into an HTML document and have it 'executed' is really neat (I 
think CGI's are ugly, whereas code in the delivered doc itself is 
elegant - my opinion, YMMV). I've run PHP on Solaris and Linux, and 
used a lot of the contributed code.

Since I found out about Zope, I've desubscribed myself from the PHP 
lists and been focussing on Zope almost entirely. I posted a message 
a while ago 'Tough Questions about Zope' and got some excellent 
answers, for more details I'd check it out in the archives.

PHP3 is a scripting language, and is relatively easy to get started 
in. I may get a 16-ton weight dropped on me (in joke) but I think 
that if you're used to scripting languages already, you may get your 
application up and running faster in PHP3, as Zope scripting ('DTML') 
requires a bit of a mind-flip.

However, once your application gets more complex, I think you'll find 
that Zope will start to pull ahead of PHP3 and eventually pull very 
far ahead. The list of things that Zope provides 'out-of-the-box', 
which are very difficult to do in PHP3 is pretty long; access 
permissions (at varying levels) at a per-directory and per-'object' 
level, editing of web pages online, *undo* - yes, undo!, and versions 
are the things that come to mind initially. There are many others. 
Obviously, there are some things in PHP3 that are a bit 'unusual' in 
Zope too (setting variables for instance! :)

The scripting language of Zope is Python - I've bought several Python 
books (personal rec: Internet Programming in Python by Watters, van 
Rossum and Ahlstrom - top geezers in the Python world) and have found 
it to be quite a beautiful language. You can't install Python 
programs 'directly' into your DTML document, but 'External Methods' 
seem quite easy to write. Once you become familiar with 'Products' 
and what *they* can do, your jaw *will* drop.

> Are there people, using PHP3 next to Zope?

This is a question I asked. The upshot is that it's pretty difficult 
to do in seemless way with current implementations of Apache (ie more 
or less impossible) but that a later version will do that.


> ps. Has Zope the capability to easely make these scripts? I mean not
> text-based , but in a certain IDE or RAD application?

I would say, yes. I would suggest reading the FAQ, then the 
documentation, reading the documentation again (especially the DTML 
and ZSQL documents), read it once more and then if you do decide to 
try Zope over PHP3, have a go at your application. I think that it's 
highly likely that you will be able to get by with just some DTML and 
a database connection.

I'm not knocking the documentation here - the DigiCool guys (and 
gals?) have relatively recently embraced the open-source concept and 
seem to be doing 10 things at once.

I don't think you're stupid at all! :) There are some new and unusual 
concepts in Zope that many people will not be familiar with 
(particularly if you're coming from a 'traditional' web-publishing 
environment).

If it helps, I've been in contact with several other people, both 
here in the UK and elsewhere who are *extremely* excited about what 
Zope is and what it can do.

> Thanks in advance.
> Kind regards, Tom.

You're welcome - I got a lot of help starting out, just trying to 
pass it along... :)

Maybe It's self.l that causes the error. It's hard to understand what
you want, but I feel it should be

   for i in l

Maybe I can help you with this. The traceback you get is probably the
standard error raise in ExternalMethods. To debug external methods I use
try/except/raise code blocks and when I get an exception I return it to
the screen. Something like this

def mymethod(self):
    try:
	mycode
    except:
	import sys
	return sys.exc_type, sys.exc_value
    
    return something

Not yet. ZServer is multithreaded, but Zope itself isn't. This is because
the BoboPOS (cuurent version 2) doesn't support concurrent access. The all
new ZODB 3 will support this, and then Zope can (will?) become
multithreaded as well.

   So I have some time before I'll see problems with concurrent access to
SQL server! :)

Ok, I'm dumb.
After some digging, I found that the problem lies in
the expression 'self.l'

'self.' gives access to the object hierarchy, not the variables
namespace.

So, I solved my problem by writing 'self.REQUEST['l']'
instead of 'self.l'

Also, I think that this should be clearly documented.
Apparently, the only way to acess variables namespaces
in external methods is through self.REQUEST
This confuses a 'normal' python user whose variable
namespace is usually accessed through self.

Can someone confirm (or infirm?) this?

I believe that you can just ask for it in your function signature:

def my_method(self,l):
  return l + ' is cool!'

In your external method l is a local variable. You can access it by simply
referencing it. something like

def spammethod:
	l=[]
	for i in [1,2]:
		l.append(i)
	return l

It can do the same thing, and more.  This isn't a hack on PHP3, but Zope
has many more components and widgets out of the box.  It's also object
oriented, which helps when your components scales, or when you want your
application to suddenly be stitched into four other application six
months from now that you didn't forsee.

>Or is this a complete different application? 

PHP has it's niche.  Tony 'tone' McDonald mentioned that he thought code
inside HTML is elegant, and it is, but it's even more elegent when that
code is for the layout of your user interface only.  Mixing application
code with HTML, or worse yet, making your entire HTML document one huge
script, is not so elegent.

Zope is an Application written in a scripting language (Python) that is
based on several components also written in Python and C.  One of the
components of Zope is Document Templates (DTML) which is also a
scripting language.  It's a bit complex, much more so than PHP's
underlying system.  Tony also mentioned that PHPs database itegration is
excellent, and I'd like to add that Zope's is also top notch.  A
particular nice thing about Zope is it's database abstraction layer,
what we call Database Adapters.  You can write program for any SQL
server and just change the DA when you change databases.  Or your app
could use two databases transparently; the DTML programmer wouldn't need
to know which database is being queried, it would just be a case of
calling the write SQL methods.

This also give some compartmentalization.  Your Python expert writes
your external methods, your SQL expert manages DAs and writes ZSQL
Methods, and your DTML/user interface expert uses all of these methods
to layout the application.

Comming soon.  The problem is (rumor has it) that Apache sends Zopes
output directly back to the browser, not giving it a change to run
through any other handlers, like the PHP one.

There is a web based interface.  The (IMO) ultimate programmer interface
is emacs, which can use Zope with FTP (if your using ZServer).

Whew.

Zope is a web application platform.  It is a framework for writing
applications over the web.  It is more than this, because it supports
more protocols than HTTP, but for your purposes you can call it a web
app platform.

Zope provides you with a standard set of services that your application
can build on.  Services include DTML, trasparent persistence of your
data, interface to databases, a management interface for developing and
managing your application, and a whole slew of out of the box objects
for you to use (like documents, files, methods, DAs, mail transport,
etc...)

Many people have mentioned Python in responses to your question.  Python
is an incredible language, but I think the application you described can
be done easily in Zope with no Python at all.  All you need is DTML,
some ZSQL Methods, and a good design and your done.

These 'benefits' you feel you might be missing out on you might not
need.  One of Zope's best features is the fact that you can just use the
components you want.  In fact, it sounds like you may just need
ZPublisher by itself.  If you go to our site and look at the Components
section you'll see where you can download it. ZPublisher is just the ORB
part of Zope, it traverses your python module and calls your methods
based on the URL.

Now, you can still USE Zope with these application you write.  Even if
you write a pure ZPublisher application, you can then plug that
application right into Zope with the External Objects product available
in the contributed area.

I am trying to use the ZMySQL component on a Solaris 251 machine,
I have Pyhton 151 installed from sources and MySQL 3.22.16 from sources.
Zope,Python and MySQL all work fine and the ZMySQL module compiled fine
but when I try to "import" it from python I get the following error:

I also tried it from a FreeBSD machine with pretty much the same result.

Any ideas.????

Hi all,
just thought I'd check my sanity here...

the way to get roman numerals showing up as the label on a batch object is :

        (Previous <!--#var previous-sequence-size--> results)
        </a>

      <!--#/if previous-sequence-->
isn't it? - I get a NameError, with the following traceback ('sub' is 
nowhere in my document btw)

<!--
 Error type: 
 Error value: sub

....

Subject: [Zope] installing Zope
Message-ID: <3.0.1.32.19990326200338.009363e0@poirot>

Hi,

Thanks to all the reply I got for my question PHP3 or Zope.

I'm wanting to give it a try, but ....

I've RedHat 5.2 installed with running Apache

I'm trying to install Zope, but am expiering some problems :

I've downloaded the binary and installed it into 

 /usr/local/dc/Zope-1.10.2

installed it with ./install -sAdmin:Admin

the var directory of Zope is permissioned for nobody (done by Zope)

As in the manual, Zope created access with Admin:Admin, but it says login
with Zope:Admin

copied the Zope.cgi to the directory /home/httpd/cgi-bin

I want to use it with Apache so I had something to change in the conf file
of Apache... Apache has 3 conf files. At the moment it is written in all 3
of the files (because none of them work!).

This is the piece of script I've written : (from WEBSERVER.txt)

#Zope configuration maps /Zopz/ to the Zope.cgi CGI script

RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP-CGI-AUTHORIZATION:%1, t=application/x-httpd-cgi,l)]

When trying to browse to http://localhost/cgi-bin/manage I get the password
dialog... I enter Admin , Admin and am refused (same with Zope, Admin) ....

What am I doing wrong?????

--------------------------------------

Now try to use ZopeHTTPServer

I can't find anywhere the file serve.sh

BUT I tried to start it with start

then going to webbrowser http://localhost:9673/manage

I get a message of DNS problem etc...

So not even a question of password...

----------------


Can somebody tell me what I've done wrong? I want to get it to work with
Apache... What do I've to do?

Thanks in advance,

Tom.

Hi,

I noticed that if you're browsing two different Zope sites using the
same Netscape, the management tree on the second one is incorrectly
displayed (the COLSPAN is increased by two).

Has anyone noticed this before?

Ok, I've updated the package to remove the bug that killed it after the
first shutdown/cache loss. The _v_ technique certainly served to prevent
the saving of the variable, so when the system came back up, before I
use the _v_ variable I was testing it to make sure it was higher than
the stored value. I added a test to make certain that it exists... Is
there a way to register a function (or some __func__) that gets called
the the instance is reloaded?

It seems fairly stable now, so I'm calling this 1.0. 

Please send bug reports to shawh@sths.org.

BTW, has anyone actually tested this other than me? 
I thought from the comments I had read on the list that there were a
fair number of people who were perturbed at the lack of a counter in
Zope. Was I wrong? Am I flogging a dead horse here?

Subject: [Zope] Method icons
Message-ID: <36FBFDF1.23E9F89A@digicool.com>

Hi all.  Here's a minor issue I'd like to get some opinions on.

  There are some ideas in Zope that cross 
  object types in Zope, like folders, methods, and
  content.  We reinforce the idea of folders
  by giving folders icons derived from folder
  icons.  I'd like to do the same thing for 
  methods.

  The basic idea is that there should be
  some basic icon that indicates that something is
  a method.

  It should be possible to decorate the icon to 
  indicate a particular type of method, such as adding
  angle brackets for DTML or adding a table grid
  for SQL, or OO (or glasses ;) for Python.

  Note that one complication is that the image 
  should fit in a 16x16 icon.

I've put some ideas at:

  http://www.zope.org/methodIcons

I'm curious what folks think of these and whether
anyone has any better ideas.

Jim

Hi Tom,

Try this:-

RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1

Hello!

   I am creating a record on Zope on postgresql.org:
http://www.postgresql.org/software/detail.cgi?oid=3440544

   I need a short informative description on Zope. Something like "Zope is
opensource web application platform - software complex for creating highly
dynamic web-sites".

   What is contact e-mail? I wrote zope@zope.org. Shouldn't it be
info@digicool.com?

Subject: [Zope] Automatically creating instances for each user?
Message-ID: <36FE35BD.AEBBC507@dougiamas.com>

Hi,

I'm new to Zope, but I'm eagerly learning it.  I like the
paradigm - it seems to fit the way I think.

This is my first post here.  I've hit a snag, and I'm hoping
someone more experienced can point me in the best direction.

I'm developing an application that needs user-modifiable pages.
I already have a Zope form where the user can edit text properties
of an object, and another page that displays those properties as HTML.

My problem is, I want each authenticated user to be editing their 
own instance of this object, and I also want the URL to be the 
same for each user.

eg  fred sees http://host/mypage as fred's editable page
    mary sees http://host/mypage as mary's editable page

What is the best approach I should take to achieve this in DTML?

Cheers,
Martin

Could someone please provide an example of what I need to use to create a
Z MySQL Database Connection...suppose I have MySQL running with a database

I am a bit confused as to what ZMySQLDB is asking for.

Yes, the documentation is a bit unclear about this.

You'll need a Database Connection String like this: 
"webdb joe password".

"webdb joe password" should work if the database is running on the same
machine.

Message-ID: <3.0.1.32.19990329102524.0097e170@poirot>

Hi all,

Well, now I don't understand it anymore....

Just back from the weekend (where on Friday I had these installation problems)

Now went to the Zope directory and what did I saw? The 'Start' and 'Stop'. 
I wrote ./Start and then surfed to the correct address and it works!

Why did'nt it worked on Friday? The whole weekend searching for a solution
and then it appears it isn't needed... (almost)

But, still I would like to work with Apache... Why? Because I've heard it's
the best in web-servers... (I don't know it's through, but I believe it) Or
is the comming ZServer better?

Now, I believe I have to recompile apache again to make it ready for Zope,
isn't it? I thought I only had to put it in one of the configuration files,
but instead you've to write that script in the ./configure file.

Hi again,

I've a Postgress database with some data I want to use with Zope. So I've
to install an external driver. 

Is it so that I've to recompile Zope? This means that I've to download the
source and not the binaries of Zope, like I did... Isn't there a simpler way?

Because when I need to recompile, I've do download also all the correct
libraries of each program... sghh. Please, let there be a simpler method.

Thanks in advance.

Tom.

Hi,

 Can you send me an url where I can see your work? 

 So I can get the idea (especially database related) what is possible with
Zope.

I found Zope's HTTP logs at:

   ...zope/var/server.errors

which is what I need to monitor the server, but they don't
appear to be including usernames (just a '-' in that field).

How can I turn logging of usernames on?

   You need to install and compile ZPygres Database Adapter and add it as
described in ZPygresDA docs. You don't need to recompile Zope.

AUTHENTICATED_USER.getUserName() returns the name of the current user. You
could use this in the DTML of mypage to select the object you are working on.

Hi all,

I'm using Zope 1.10 with IIS 4.0 on an NT box.  All is working well, I just
have one small query which is slightly off topic, maybe.

The URL for Zope is 'http://localhost/scripts/z.exe' and I would like it to
be 'http://localhost/z/', I know that with Apache I could do a rewrite and
this works great with Apache, but does anyone know how I would do something
similar with IIS.

TIA

Nope,

With that definition, my_method expect to be called with the arguments
set, eg <!--#var "my_method('Zope')"--> to display "Zope is cool".

However, I want to get the variable l from the namespace. (application
variables made with REQUEST.set, Folder or document properties, etc.)
The question was: is self.REQUEST the only way to access the
variable namespace? And the only way to *modify* the variable namespace
from external methods (with self.REQUEST.set)?

By the way, I'd like to thank Stefan Franke and Pedro Vale Lima who
gave me a pretty quick answer. I did find the answer before they wrote,
but anyway, a thank is not that expensive :-)
Also, thanks to Paul who gave me such a useless answer. :-) (just kidding)

The pcgi.log reads:

Have you already seen this behavior? Does someone have an idea of

The error occurs because a value is appearing in
a pcgi reserved header record, possibly because your
application is sending something to stdout.  I'm
not sure where to tell you to start looking, but
if *all* you have done is uploaded .dtml files to
trigger the error, that's probably the place to
start.  I'm honestly confused why this should
happen.

Usually this means that the Zope process is unable to start up
for some reason (an import error, syntax error, etc.). I'm not
sure how changing DTML document objects could cause this, though.
You didn't happen to change any DTML that is read from the disk
(e.g., HTMLFile objects used from Zope, installed products or 
external methods) did you? If so, there is probably a dtml syntax
error that is being raised at startup time.

You are positively right.
I stupidly wrote <!--#var "some_method(var0=value0, REQUEST)"-->
notice the non-named parameter after a named parameter.

I haven't tried it yet with other publishing mechanisms (ZServer,
ZopeHTTPServer,
which don't use PCGI), but if these servers also dies for such oddities,
this might be
a bug in error handling. Stay tuned for more informations.

Many thanks to Brian and Jeff who took the time to respond to me.

Anyone out there using Principia still? Have you seen this?

Message-ID: <613145F79272D211914B0020AFF6401907BBDA@gandalf.digicool.com>

Greetings,

As promised, it is possible now to browse the Zope public CVS repository
through the web.  If you're interested in looking at the latest Zope
developments, this is a good place to start without having the check out
your own copy.

This site is also handy for viewing the various evolutions of Zope, and
for getting pretty colored diffs between versions.  If you want to know
the difference between two recent versions of a certain file, cvsweb
will show you in glaring full color.

The web view of the Zope CVS is more fragmentary the the view you get
with the 'cvs' command.  If you want to check Zope out of the public
cvs, it is recommended you just check out 'Zope', which is an options
not shown on the web cvs.  The public CVS uses its module file to stitch
together the various components that can be seen on the web view into a
Zope distribution.  Complete instructions on how to do this can be found
at:

http://www.zope.org/Community/CVS_public_access

The web interface can be found at:

http://www.zope.org/cgi-bin/cvsweb.cgi

In case you're curious, this is not a Zope module but a CGI script
written in Perl.  It can be found at:

http://linux.fh-heilbronn.de/~zeller/cgi/cvsweb.cgi

The first release of Aqueduct docs had a table with examples of
connections strings for some databases. This table disappeared in the
latest docs. Shouldn't it be the case to take it back?

Yes, I've seen it in Principia and Bobo for cookies in the form:

.com.au  TRUE    /       FALSE   933422008       MC1 GUID=083F5B8E21DE11D28B2C08002BB74F3F

The two problems being that cookies are usually only seen by the domain
that registers them, but some badly configured servers (most probably
Microsoft servers by the look of the cookies) only list the last two parts
of the domain name. This is fine for blah.com, but for overseas domains
like blah.com.au it means the cookie is returned for ALL .com.au sites.

This wouldn't be a problem, but since the cookies are returned to Principia
in the form:

MC1=GUID=083F5B8E21DE11D28B2C08002BB74F3F

parse_cookie breaks since it looks for key value pairs WITHOUT an equals
sign on either side. The extra = really confuses it.
To fix it change the re in parse_cookies in cgi_module_publisher.py from:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-=\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'
                     ),
 
to:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'

I'd like to be more precise. Suppose my_method is:

def my_method(self):
    if self.REQUEST.has_key('my_var'):
        return "oh yes"
    return "boooo"

Believe me or not, the result is:

boooo
boooo
my_value

You can now understand why I ask how to access the variable
namespace from external methods. How can I test the existence
of my_var, and access its value???

Keep the good work, I might ask you some of your photos for

Subject: [Zope] Frustrating
Message-ID: <3.0.1.32.19990330122825.009293a0@poirot>

Hi,

I'm getting really frustrating on this subject. Pff, I believe the
Zope-people have made already a great effort in their documentation. So I
guess my problem is my own bad english. shhg.

I finally got the Postgressql adapter compiled, thanks to two great people!
Thanks for this already.

But now I'm confused? How to use it in Zope? When I go to the product
management I see the all the installed products including : ZPyGreSQLDA
(broken product APyGreSQL).... I guess here is already something wrong
(broken... is not a positive word :-( )

But then, how can I work with it? How can I use it in Zope...? How can I
add it to the 'Add list' . I read of a connection string... but where to
place it?

Sggh, I've read in the manuals, Q&A, ... but I still don't get how to use
it....

Please, somebody, help...!

Thanks in advance,

The Idiot,

Tom.

First thing, if your product is broken you won't get anywhere. So, first
step is to delete the broken product, and shutdown and restart your zope
server. This is because Zope apparently won't replace a broken product
with a working one. 

If it is still broken, click on it, and then on the screen that comes
up, look for the 'traceback' tab on the top of the screen. Copy this
traceback and mail it to the list. 

If your product no longer says broken, then you will be able to go to a
folder above where you want to use SQL methods, and from the pull-down
menu beside the add button, choose to install the SQL Adapter. 

I don't know for certain the format for the connection string, but if
you go to <zope_homedir>/lib/python/Products/ and look in the directory
for the ZPyGreSQLDA and read the top of any *.py file you see, it should
say. 

Once you have a working adapter, you can add an SQL Method, and it will
list your adapter's id on its list of db connections. 

From this point on the documentation in the SQL Guide should be
sufficient.

Good luck!

Using Netscape 3.04, I can't edit the text in DTML Methods. I get the
textbox, and I can place my cursor where I choose, and scroll through
it, but I can't type in it, I can't paste into it. I can copy the whole
contents, make a DTML Document, paste it in, and edit there! Any idea
what's going on? When I access it from Netscape 4.07 on Linux it works
fine...

    If I'm really lucky, I might be getting a contract to put together a
rather large site which includes selling the client's product over the web.
They'll want to be doing credit card transactions.  Has anyone been working on
a shopping cart app for Zope, or perhaps even utilities to interact with a
credit card transaction service?  It's much quicker to buy than write!

Well, this is an interesting question. In my experience, seldom do people
try to munge the DTML namespace from within an External Method. I guess it
could be done (perhaps by passing the special underscore variable to an
External Method), but I wonder if this is really the best way to solve your
problem.

Well let's see what's going on here. You call my method, it acquires the
REQUEST object and looks for a 'my_var', doesn't see it and returns
'boooo'. so far so good. Now you push a namespace containing only 'my_var'
on to the DTML namespace stack and call the method again. Not surprisingly
the method does the same thing as before, it acquires the REQUEST and finds
that it does not contain 'my_var' so it prints 'boooo'. Finally you call
'my_var' which is found in the DTML namespace and 'my_value' is printed.

So the lesson is: the DTML namespace is not the same thing as the REQUEST
object.

For more on how DTML namespace works see my advanced DTML how-to:

http://www.zope.org/Documentation/HowTo/DTML

My advice to you is to keep things simple. It's easy to confuse yourself
with the complexities of DTML. In general, I would suggest that your
External Methods take well defined arguments and return results, rather
than modify the objects passed to them. Then allow the DTML to pass those
arguments and munge its own namespace in response to the results of the
External Method. Of course, this schema isn't always the right one. Finally
I would suggest that you, don't munge the DTML namespace from within an
External Method unless you have a good reason to, I think that this would
make the DTML even harder to understand.

Good luck.

Can I recover? The db doesn't contain anything important so it's really
okay to reinstall, should that be neccessary.

It looks like you're running an older release 1.9.x something?  1.10.x
will automatically fix the database under 90% of the circumstances by
simply truncating the bad record.  This should fix your problem.

BTW, it's always helpful to give information on what release of Zope
you're using.

At a minimum, you can truncate the data file (var\Data.bbb) 
at the position indicated. (Let me know if you need help with this.)

You could also just delete the database (var\Data.*) and
a new database will be created when you restart.

I'd appreciate it if you'd send me the corrupted database
as a zipped or gzipped attachment in a private email.

Also, what version of Zope were you running? What OS?
What products (not included in the Zope distribution) did
you have installed?  Can you tell me anything more about what 
might have led up to this?

I think what you want is access to the dictionary's items() right?

<!--#in "dictionary.items()"-->
  <!--#var sequence-key--> : <!--#var sequence-item-->
<!--#/in-->

The mapping attribute is not relevant here. It means treat
sequence-items as mappings not instances, that is to say, look up vars
with __getitem__, not __getattr__.

The DTML User's Guide is your friend.

I'm trying to convert shell scripts into DTML methods.

Please excuse the pseudo code. I'm using it to represent the problems
that I am addressing.

set basket_total=0
set taxable_total=0
foreach item( 'apple', 'peach', 'soap', 'pear', 'plum', 'magazine' )
 if (! isfood($item))
  @ taxable_total = $taxable_total + price_of($item)
 endif
 @ basket_total = $basket_total + price_of($item)
endfor
print "Of the $basket_total total, $taxable_total is taxable"


1) Can I generate an explicit list rather than getting it with
as the result of either a database query or enumeration of an object?

2) How do I generate "local" variables.
I know that I could use the REQUEST variable as a global property store.
However, because of nesting, global (REQUEST) variables are not desirable.

I'd like to say something like the following:

<!--#WITH "LOCAL_NAMESPACE (basket_total=0, taxable_total=0)"-->
 <!--#FOR "['apple', 'peach', 'soap', 'pear', 'plum', 'magazine']"-->
  ...
  <!--#SET basket_total=basket_total+price ...>
 <!--#/FOR-->
 ...
 <!--#var basket_total--> 
 ...
<!--#/WITH-->

Does Zope's DTML have constructs to address either of these?

Message-ID: <370125A1.305733AC@kw.igs.net>

Please excuse my lack of zoping intuition but I hoped someone could help
with this problem. I read all the doc's I could find but seem to be
missing something. It goes like this...
I have a ZSQLMethod that returns some tuples. There is a field in the
tuple which I wish to use to lookup an external file and return a jpeg,
if available.
I've created an external method called 'getPic' which I wish to pass the
key field to locate the file with but I can't seem to get at the
variable.
e.g
----------
<!--#in sequence -->
  <td><!--#var pic_key null=""--></td>
  <td><!--#var "getPic( <!--#var pic_key --> )" --></td>
<!--#/in -->
----------

This doesn't work for reasons not obvious to me.

I've tried creating a class to handle the records. No go.
Basically, the External method can't get at the vars defined on each
loop thru the sequence returnd from the SQLMethod.

Any insight would be appreciated.

thanks

Zope send it to lpr? I have zero experience there. :-(  

Any suggestions?

Brad,

Thanks.  Regretably, we aren't really using any Microsoft Products (Too
bad, we could have got a virus yesterday :-()  The clients are(and a
browser on the server could be) running Netscape Comm 4.08.  I'm sure
there is a similar way of controlling Netscape--Any body have a guess?

I am thinking about implementing a dynamic site using
zope and as little python as I can get away with.  The
site is modeled after
http://c2.com/cgi/wiki?WikiWikiWeb  

This is a dynamic site in that all the web pages are
dynamically generated and you are allowed to edit any
page right from your browser (sound familiar?) and also
create new pages very easily.  There are many other
implementation of wikiwiki (see the WikiWikiClones
link).

I am interested in any creative ways of dynamically
generating the pages and storing the underlying date in
the objectDB.  Thanks!  Mark

Thanks for your answer.
In fact, I want to write external methods to replace DTML methods which work
like a charm, but are not very readable (a lot of iterative stuff, given the
fact
that mySQL doesn't support sub-select) and pretty slow.
I have used python for several years right now, but DTML is new for me.

My users can search in our news database in several ways, that are
covered by different SQL queries. However, the output of all these queries
are the same, so I use a single DTML method to display the result.
So the name of the ZSQL Method is only known at runtime, and I use something
like:

<!--#in "_[query]"-->

to display the result. The arguments of the query are taken from the
namespace.
I can also write:

<!--#with "_.namespace(cooked_arg0=some_expr(arg0),
cooked_arg1=some_expr(arg1)"-->
<!--#in "_[query]"-->
<!-- ... -->
<!--#/in-->
<!--#/with-->

If I want to cook some args before feeding it to the query.
All these work from DTML.

Now, I want to write this in an external method.

def results(self):
    for record in getattr(self, self.REQUEST['query'])(self):
        pass # do watever

'query' has to be in the form REQUEST variables (that is not a problem), but
I cannot be sure that any arguments that the query need are all accessible
through
REQUEST.

I wrote this to test wether an external method has access to the entire
namespace,
or only to REQUEST variables.

So I come back with the question: is there any way to access the DTML
namespace
from an external method. Apparently there is not

>For more on how DTML namespace works see my advanced DTML how-to:

I have already read it.
By the way, let me ask you a question (again. I already asked that, but the
answer
was not very clear, and I finally gave up):

<!--#var my_var--> and <!--#var "_['my_var']"--> are the same.
So instead of writing:

<!--#if var0--><!--#if var1-->
<!-- ... -->
<!--#/if--><!--#/if-->

I usually write:

<!--#if "_['var0'] and _['var1']"-->
<!-- ... -->
<!--#/if--><!--#/if-->

But almost everyone told me that

<!--#if "var0 and var1"-->

also work. So I wonder: are <!--#var "var0"--> and <!--#var var0-->
the same??? The DTML User's guide say that in an expression,
variable are not called by default, but _['var0'] calls var0 if possible.

To keep things simple mean I have to write several times the same external
method
with different queries and differents arguments each time. this is not what
I want.
I can remember that in DTML I only need one DTML Method.
I would really like to replace some of my DTML Methods with external
methods.

That's enough for today. Let's take some rest :-)

Message-ID: <129.78.8.1.126.8141.922865008.414.1008>

I can use the following in a DTML document to call a specific method:

  <INPUT TYPE="submit" NAME="mymethod:method" VALUE="Delete this item">

But what if I wanted to have lots of them?

I'd like to have multiple SUBMIT buttons, all referring to the same method
but diffentiated by parameter - possible?

Ie: something like:

  <INPUT TYPE="submit" NAME="mymethod:1:method" VALUE="Delete item 1">

passing the parameter '1' to 'mymethod', and then later

  <INPUT TYPE="submit" NAME="mymethod:2:method" VALUE="Delete item 2">

and so on.

Incidentally, is the ':method' trick documented? - I can't find it in
the DTML guide.

Message-ID: <3.0.1.32.19990331105851.00931700@poirot>

Hi all,

First of all, thanks to all with their great support and help. At the end
of last week I found out about Zope. It looked really interesting, so I
wanted to give it a try. Monday after several problems and with lots of
help I could manage to enter Zope. Not from Apache as I would like, but
from the HTTPServer.
Next I wanted to attach Zope with my PostGresSQL demo database. Boy, did it
gave me some problems (and all because of my lack in knowledge of Linux).
But again several people helped me and today it is solved! Yep, it is done,
the hard work can begin. Now, I've to convince other people that Zope is
the way to follow. 

At first blink, Zope is a really nice and great product. I hope it will get
the attention it diserves.

Still, some work on the documentation, although they already did a great
job! Most thingies are written down.

Kind Regards, Tom.


Now some questions:

1. Have you used CSS-sheets in Zope and how did you use them? Did you
incorporated them into Zope or not? Have you got a little sample?

In Zope, this is pretty easy.
Create a property at your top level of type 'lines' and called 'css' 
(you can also create a DTML document/method if you like). Populate it 
with good CSS things like (this is from the Zope site itself 
actually).

<STYLE TYPE="text/css"><!--
	.clean { font: 10pt Verdana, Geneva, Arial, sans-serif }
	.clean dt { text-decoration: underline }
	th.clean { font-weight: bold; }
	.headbottomrow td { border-bottom: 2px solid #936 }
	.header { color: #004488; font-weight: bold; font-size: 14pt; 
font-family: sans-serif }
	.smallclean { font: 9pt Verdana, Geneva, Arial, sans-serif }
	.smallclean dt { text-decoration: underline }

H1, H2, H3, H4{
  font-weight: bold;
  color: #000000;
  font-family: Verdana, Helvetica, sans-serif;
}

H1{ font-size: 16pt;}
H2{ font-size: 14pt;}
H3{ font-size: 12pt;}
H4{ font-size: 10pt;}

/* end hiding content from old browsers */ -->
</STYLE>

In standard_html_header you put something like
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#var css-->
</HEAD><BODY BGCOLOR="#FFFFFF">

and you're away...

You may want to change standard_html_header so it doesn't crash if 
css is not present.
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#if css-->
<!--#var css-->
<!--#/if -->
</HEAD><BODY BGCOLOR="#FFFFFF">

Now where it starts to get really cool is that all your documents 
*below* the top level get the CSS information by acquisition, but you 
can change CSS information in folders by creating a new CSS property 
or document within that folder.

Tres Neat.

I just installed Zope on a Netscape Enterprise Server (3.6). I compiled
and installed the nscgiauth plugin, and all seems to run OK, except for
one thing:

When I try to add items to the site through the manage screen, I get:

        Not Found

        The requested object does not exist on this server. The link you
followed is either outdated,
        inaccurate, or the server has been instructed not to let you have
it. Please inform the site
        administrator of the referring page.

When I open the frame into a new window, I see that the URL looks
something like:

http://www.foo.bar.net/Zope/GATE/manage/.?%3Amethod=manage_addDTMLDocumentForm

When I edit the URL by hand to remove the "."

http://www.foo.bar.net/Zope/GATE/manage/?%3Amethod=manage_addDTMLDocumentForm

It works fine. What is going on here, and what do I need to do to change
it? I plan on having other people from other departments access resourses
on Zope to create their own objects, and I need this to work right out of
the box.

Thanks in advance for any help.

First off, your the first person (I think) that has come forward with
the information that they are using any version of NES higher than 2.0,
which is what the nscgiauth plugin was written for.  As I have heard
(but don't know) there were some significant changes between the 2.0 and
higher versions of the NSAPI.  So, that you got it to work at all is
pretty good.

This is unreported behavior, which leads me to think that nscgiauth
needs a little tweaking.  As nscgiauth is unsuported you will have to
experiment with this a little.

If your looking to showcase this and you can't spend any time working on
nscgiauth, I would suggest using either Apache, ZServer, ZopeHTTPServer,
or IIS, all of which Zope runs out of the box with.

I think that you missed my point.

"I" can write python just fine. However, every time something changes, new
python functions must be written. It is desirable to allow 
"DTML programmers" to do simple things which they can accomplish with simple
local variables.

What I think I should do is create a function, "LOCAL", similar to REQUEST
that stores temporary variables. Unlike REQUEST, LOCAL would be bound to
the namespace multiple times, each with a different context stack.

<!--#with "_.namespace(LOCAL=LOCAL.create('basketTotal','taxable')"-->
  <!--#call "LOCAL.set('basketTotal', 0)"-->
  <!--#in "['pear', 'peach', 'boot']"-->
    <!--#call "LOCAL.set('basketTotal',
                             LOCAL.get('basketTotal')
                             + priceOf(_['sequence-item']))"-->
  <!--#/in-->
The total basket will cost <!--#var "LOCAL.get('basketTotal')"-->  
<!--#/with-->

Or perhaps we can trick the namespace into showing basketTotal without
the LOCAL.get reference.

Can the Zope server provide virtual domains or do I need to use Apache??
Right now I have Apache set up with 4 virtual domains and would rather
just use the default Zope httpserver.

Well, the only difference that stuck out to me were the include files for
NSAPI.
nscgi  calls for several, but in 3.x all the header files have been
combined into
one, "nsapi.h". I modified nscgi.c to call for this one header file and it
compiled
cleanly. It does its job very well, and am not all that certain that the
problem I
am having is related to nscgi at all.

Well, I am a contractor and really don't have that option. I have tried to
sell the idea of using Apache here, but they have already bought massively
into Netscape. If I cannot get Zope to work, I may end up recommending a
commercial package, at least for this case.

Message-ID: <Pine.LNX.3.96.990331124956.26207A-100000@taos.kavi.com>

Has anyone built Zope on a BSDI machine? BSDI doesn't support shared
libraries, so everything has to be statically compiled into python.
I just got it to build (python w_pcgi.py finished), but there doesn't seem
to be a new python binary anywhere with everything compiled in. To get it
to compile, I went through and deleted all the '*shared*' from the 'Setup'
files. Any tips?

As a side note, I was planning on using the binary porting kit to get it
built, then contributing this back to the community. But the porting kit
is still Zope-1.9. Is there any plans to update the porting kit.

Thanks in advance for any help,

Subject: [Zope] NotMail 0.1.0 and IMAPAdapter 0.1.0
Message-ID: <613145F79272D211914B0020AFF6401907BBF0@gandalf.digicool.com>

Greetings,

NotMail-0.1.0 and IMAPAdapter-0.1.0 have been posted to the prereleases
area of the site:

http://www.zope.org/Download/Prereleases/Mail

These are first beta cuts.  Both programs are also available in the
public CVS.

IMAPAdapter allows you to work with IMAP folders and messages in the
context of an authenticated IMAP user.  Using IMAPAdapter, it is very
easy to build IMAP client functionality into your Zope site using DTML.

NotMail is a simple web IMAP client that requires IMAPAdapter.  Its mail
purpose is to verify the operation of IMAPAdapter and to provide an
example implimentation of IMAPAdapter's client functionality.  NotMail
is mostly DTML, and what Python there is is just specific to sending and
replying to mail, all other functionality comes from IMAPAdapter.

It is important to note that IMAPAdapter looks like a user folder to
Zope, in Zope parlance, we call this a user database.  It's not a user
folder, because it doesn't not contain users.  If Zope tries to validate
a user against an IMAPAdapter, the IMAPAdapter will contact the IMAP
server, try to make a connection with the uid:pwd that the browser
supplied, returning either a user object or None, depending on the
success or failure of that connection attempt.

This means that using IMAPAdapter is quite simple.  Here is a snip of
DTML to display all an IMAP users mail folders with the #tree tag.

   <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

The user object that IMAPAdapter returns (if the user is valid) is
placed into AUTHENTICATED_USER.  emapFolderTree is one method of this
user object, but there are about a dozen or so more methods to do
various imap related things like adding/deleting folders and listing and
fetching messages.

If you plan on installing and trying out NotMail and IMAPAdapter it is
important to know that you can configure the roles that IMAPAdapter
associates with users that it returns.  The two default associated roles
are 'NotMail' and 'IMAPUser'.  If you want NotMail to work, you will
need to add one of these roles (or any roles you care to define as
IMAPAdapter's default roles) somewhere above NotMail/IMAPAdapter and
then assign that role the 'View' permission for NotMail's DTML Methods.

Have Fun!

-Michel

Um, what VERSION of BSDI are you using?  I haven't usd anything since
3.0, but I SWEAR it has standard BSD style shared libraries, same as
FreeBSD, OpenBSD and NetBSD... It'd be a huge step backwards if it
didn't.... are you sure it just didn't auto-detect the method right?

Alright, I guess I was jumping the gun a bit with my assumptions about
shared library support. It does support them, just not in a format I'm
used to (based on my Linux/Solaris experience). 

Ok, so then mabey I messed up in autodetecting as you mentioned. How would
you suggest I do this?

Here's a few lines of the errors it reports when trying to compile any of
the shared extensions... 

www ~/Zope-1.10.2-src/lib/python/SearchIndex 242> make
gcc  -g -O2 -I/usr/local/include/python1.5 -I/usr/local/include/python1.5
-DHAVE_CONFIG_H  -I/projects/_/python -c ./Splitter.c
ld  Splitter.o  -o Splitter.so
./Splitter.c:105: Undefined symbol _PyString_AsString referenced from text
segment
./Splitter.c:114: Undefined symbol _free referenced from text segment
./Splitter.c:126: Undefined symbol _PyString_Type referenced from text
segment
etc.... (many more Undefined symbol errors)


So... any tips for compiling the Zope extensions as shared libs? I'll
probably keep working on the static python solution, as I'm actually
making progress on this, and I really have no idea where to start with
shared libs on BSDI (no good leads on dejanews, and egroups is
non-responsive as usual).

Thanks,

Here are some things I've found in previous struggles to
get Zope compiled on bsdish systems -- I'm no guru, though,
and I've seen different things work on different bsdx flavors:

o you usually need to add -rdynamic to LDSHARED in your Makefiles

Hope this helps - please post a status rpt if you get it working, so
that the gory details will at least be captured. This is the sort of
thing that should be in an installation FAQ somewhere.

In the pcgi/Util directory, you'll find a killpcgi.py 
script.  You could hack it to perform a restart, i.e.
launch a new pcgi process after killing the old one.
This would speed up your initial connect time and be
much faster during debugging (multiple restarts).

My Zope Zen seem to have gone negative (started at zero - and just got worse
:( ) but HOW do you install it.  I could find no mention of any "lever"s in
the ZMG.pdf,
and I have tried as many ways as I could think of to get my Zope (1.10.2 on
ZAP) to read/import the FAQ product, but no cigar - not even close!

Where does one put which files, and what procedure does one go through to
invoke said "Lever" functionality.  Sorry about this, but surely I can't be
the *only* one that is totally lost.  (Come to think of it, maybe I can!)

It certainly looks like you are having a problem, but since I developed to
FAQ Tool under win32 and it works fine for me under Linux, I don't agree
with you assessment of the problem. Would you please file a bug report in
the collector including this traceback. This is getting deeper than I can

Message-ID: <010201be63c8$48369be0$147800a0@pc-pi0>

Hello,

I want to *add* content to the default standard_html_header in a subfolder
that we call, say, SF. The standard_html_header in SF reads:

<!--#var standard_html_header-->
<!-- other content-->

But since an object acquire from itself, this did not work (infinite
traceback,
obviously because the stack is filled with recursive calls)
So I wrote:

<!--#with aq_parent--><!--#var standard_html_header--><!--#/with>
<!-- other content-->

And it works for object accessed within SF. But when I create sub-folder
*under*
SF, say SSF, I end up with an error.

How could i write this?

I assume this means Zope will also appear in the Application Server list of

I meant, doing the equivalent (catching exceptions) not implementing the same

I got it working using the following code:
<!--#with "PARENTS[-1]"--><!--#var standard_html_header--><!--#/with-->
<!-- other content -->

This only works when this code is in a sub-Folder, and the standard_html_header
can be found in the root folder.

Does python have anything equivalent to Perl's taint mode? Because if it does
then this could be used. That and restricting allowable APIs from internal
methods - again, if this is possible.

Well, I found that standard_html_header were called several times, and
that's what caused the error.
Let SF/standard_html_header be:

--------8<--------
<!--#with aq_parent--><!--#var standard_html_header--><!--#/with-->
Hello!
--------8<--------

Then, when I access http://mysite/SF, I get:

--------8<--------
[pretty standard_html_header]
Hello! Hello!
This is the index_html document in SF.
--------8<--------

Why is Hello! printed twice???
From SSF, I get Hello! printed 3 times...

EGroups archives the mailinglist. At http://www.egroups.com/lists/zope you can
find a search interface, which quite often actually works.

Message-ID: <19990301132234.A682@RaVER.duck.org>

Hi all!

I know the question has been up to debate earlier on the list, but still...

I can't get Apache to send authorization headers on to Zope - even tough
I've tried to do what the doc/WEBSERVER.txt tells me to (tried both rewrite
and to let apache authenticate /cgi-bin/Zope/). I also grabbed the
latest Zap release, but that one din't work (broken?). Also had a look at
the zap.conf file and tried using some in my httpd.conf file, but I still
had no luck. 

Now - here is my current config:

Linux 2.0.35
Python 1.5.1
Zope 1.10.2
Apache 1.3.4

Something there that doesn't play well together?

If not - what is wrong??

Appreciate all the help I can get!

This may sound like a bit of an obvious suggestion, but it caught me out.

Check the Directory directive for <apacheroot>/cgi-bin and make sure that
the ExecCGI option is set.

It should look something like this:

<Directory "/www/cgi-bin">
    AllowOverride none
    Options ExecCGi
    Order allow,deny
    Allow from all
</Directory>

Apache 1.3.4 by default doesn't have the ExecCGI option set.

I don't get a traceback because I didn't "fiddle", the FAQ item shows up 
in the control panel, but is not in the Add drop-down.

I'm running 1.10.2 on NT with ZServer.

The 'fiddling' involves disbling the exception handling of the product
initialisation. Normally, a 'Levered' product, that has been distributed, has a
product.dat file. This file contains the compressed pickled reprensentation of
the product, which basicly consists of other Zope objects, with a Principia
Factory.

When Zope can't uncompress and depickle the product.dat file, you only get to
see that the Product is installed, but it doesn't contain anything (which a
Levered Product actually should), and nothing else happens or can happen. If
you want to know more on how to use the 'Lever', read up at
http://www.zope.org/Documentation/Guides/ZMG/ZMG-HTML/ZMG.html#pgfId-986684
(Zope Manager's Guide, Creating Zoipe Products).

When you disable the exception handling in initializeProduct in Product.py, and
restart Zope, it will exit with the traceback I reported.

I have reported this to DC with the Collector, but I used Win98. You are using
WinNT, which is interesting.. Something goes wrong with decompressing the
product.dat file on win32 platforms (Amos says he tested it succesfully on
Linux).

I don't want to get into a language war, but as someone who lives and
breathes security, taint mode is a joke.  Python's rexec module would be
great (as would Bastion), but this is going to require a much higher
level of ZopeZen to implement than I currently have.  Yes I know my
proposal was wrought with huge security problems, but regardless it is
valuable to a some people in the near term (such as those of us on the
STarship).

BTW, requiring write access to the file system is only trivially more
secure.

Unfortunately the ExecCGI option didn't help much. Thanks anyways. 

I'm still stuck at the
point where I get 'Authorization failed'. I've checked and double checked my
Zope/access file and I use correct username and passwd. The filepermissions
should also be set correct (according to the instructions given in the
INSTALL.txt file). Problem is, as far as I can tell, connected to the way
the rewrite module does the rewrite....

Has anyone confirmed that the way the WEBSERVER.txt file says to rewrite the
authorization header actually works?

If it works - is there someone that can say exactly how apache should be
configured and compiled to get it working (best of all also put in a working
httpd.conf also)?

And again.....Appreciate all teh help I can get!

We'd prefer that you start with the Zap distribution, as it removes a
whole bunch of variables.  Can you tell us what was the error with using
Zap?

Well the WEBSERVER.txt instructions work for me.

Find attached a working httpd.conf.

Also attahced is a module listing from my 'httpd'.

#=0A=

The only difference between your setup and the setup used to compile Zap
is that Zap was compiled on a RedHat 5.2 machine, with the stock 2.0.36
kernel.  Your using 2.0.35, does that imply RedHat 5.1?  If so there

I have defined a DTML documentproperty of type lines. Each line represents

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC3E@peter.sths.org>

You need to install python... Or adjust the Makefile.pre.in to look at
Zope's internal python, instead of trying to find the external one.

Actually, from a quick runthrough of the Makefile.pre.in, you should set
the enviroment variable PYTHON to point to the local python binary; I
mean the one internal to zope, like 

PYTHON=/home/zope/bin/python
export PYTHON

(in bash)

or setenv PYTHON /home/zope/bin/python

(in tcsh) ... (and no I am not quite certain on the syntax here).

The 'make -f Makefile.pre.in boot' appears to call $(PYTHON) with
parameters that cause it to return the proper location for the python
configuration files, etc.

Good luck.

Subject: [Zope] NotMail 0.0.5 alpha release
Message-ID: <613145F79272D211914B0020AFF6401907BAB1@GANDALF>

Greetings Zopesters,

I have been working on a little pet Zope Product project for months now.
Getting hired at digicool put the brakes on it a little but I have
finally gotten the time to polish it up a bit for alpha release.

Check out:
http://starship.python.net:9673/crew/furtrapper/NotMail

for NotMail.  NotMail is a clone of 'other' popular web-mail interfaces.
Please download and evaluate.  But first a word of warning:

NotMail is alpha.  It is being released with the intention of harvesting
other developers who are interesting in breaking it, fixing it, and
improving it.  Although it is a cool program, it is unstable (try
pointing it at Exchange!) and not complete.  I have tried to document it
in code as much as possible, and it does contain a nice README.txt.  You
are expected to be able to infer the workings of NotMail by the source,
or by telepathy, whatever.  If NotMail makes your hard drive partition
go bye-bye or makes your imap server think it's a dhcp server that's the
way the cookie crumbles.

Okay, now a word of license:

NotMail is released under the GNU General Public License.  Give yourself
a piece of mind and send the Free Software Foundation a donation.  You'd
do it for NPR wouldn't you?

Now a kind word about Digital Creations:

Digicool has been kind enough to let me waste a small fraction of my
time to release this today.  They also let me use their computer to
check my personal mail, etc.  Please don't infer that because I work for
Digicool that NotMail is a product of Digital Creations.  Please do not
submit NotMail bugs to the Collector or send reports to
support@digicool.com.  These things are for Zope and other Digicool
products.  It is ok to discuss it in the list but I'd prefer all
discussion happen using the cool Confera discussion that can be found in
the same place you can get NotMail.

Regards,

Michel

What I did:

1) Extract the Zap distro into my top level Zope dir. Entered the Zap dir and
did ./startzap. 

This happened:

'./startzap /usr/local/Zope/Zap/bin/zap: No such file or directory'

2) I figured the httpd equivalent 'zap' was broken and replaced it with my
httpd (from apache 1.3.4). Again I fired up zap with ./startzap.

This happened:

No complaints this time. Apache (or rather zap) fires up correctly, but when
I try to reach the server with netscape or lynx (http://localhost/, (I
changed port back to 80)) I get 'Document contains no data'.

Same goes for trying: http://localhost/cgi-bin/Zope/manage - I get 'zero
sized reply', 'The requested URL could not be retrived'.

Now - seems like there are some settings missing from the zap.conf file?

Or if nothings wrong - then maby give the readme-file a facelift and
make it more clear to ppl like me what to do to get it running.

Zope seems just too good to just let go!!

Hope to get it running soon

I just did a fresh install and this works for me.  Can you run bin/zap
by hand from the shell prompt?

Have you tried downloading a fresh copy of the Zap tarball?

Your own httpd binary might not be compiled properly for Zope use, check
out the Zap FAQ at http://www.zope.org/Community/Projects/Zap.  Doh, I
just noticed that this is not an obvious link from the d/l page.  I will
make it so.

The conf file that comes with zap is ok.  We and others tested it quite
a bit.

Subject: [Zope] Is a JPython implemention within the realm of possibility?
Message-ID: <93C0BE6A6D6AD211BC7400A0C9D8FE87731223@exton1.bentley.com>

I am wondering if it is within the realm of possibility that the Zope
project might eventually support operation as a Java program (under JPython)
in addition to operation under traditional Python.  I know it would probably
be a large undertaking and that there may well be better places to spend
precious energy, but I thought I'd register my interest in the prospect.

In our case it is a given that a specialized JVM will be embedded in all of
our products and more and more of our own source will be written in Java, so
code which can integrate with Java easily is all the more interesting to us.
We already have a product which uses traditional Python behind a web server
to provide an entirely through-the-web user interface for product
configuration/administration. My aim has been to replace the traditional
Python with JPython since we'll have lot's of Java stuff we'll want to be
using on the server going forward anyway.  It looks like Zope would enable
us to do what we are already doing more easily (and therefore better). So
here's hoping we'll one day see Z-over-P-over-J.

Yeah.  I know it would have to be slower.

Zope looks cool.

I am not the expert about this, but: Zope is written entirely in Python,
except for a few 'kernel' like components written in C.  If you
translate these components into Java, you might just have something
there.  I'm not a Java guy so I have no real idea.

> Yeah.  I know it would have to be slower.

From what Ken was telling me JPython is actually quite well designed and
speedy, even for a Java program. :)  If you've commited yourself to Java
then I assume you've allready resigned yourself to the performance
penalty and are considering it in your engineering goals.  Performance
may not be your primary goal in the first place.

This was one of the things that I hoped to see by going Open Source.  So
far there have been ports to operating systems that we just wouldn't
have supported, which is a great to see.  I'm intrigued by someone that
really knows Java picking up a JZope effort.

As for Digital Creations, I doubt you'll see us focus on it unless one
of our consulting customers requires it.  Same old story -- never
enought time :^(

Subject: [Zope] Connecting Zope to Sybase: Linux or Irix ?
Message-ID: <199903011940.LAA18485@sam.engr.sgi.com>

I'm just beginning with Zope, and just beginning with a
project to develop some new software product management
(bug tracking and such) tools for use within Silicon
Graphics (SGI).

Zope appears to be an excellent fit for many of our
needs.

I will need to connect with an existing large Sybase
database (the existing bug data).

I can freely choose to use either Linux or Irix for
the server side operating system.

From which server O.S. would it be easiest to get Zope
connected to Sybase?  Something I read on www.zope.org
led me to suspect that I should use Irix, so that I
can use our Sybase licensed library, and that Linux
wouldn't work, because of a lack of the needed library.

Is that so?  Any other obvious factors that I should
consider in this choice?

Hmmm - I'm a slackware guy. And no glibc guy either....

Still the zap bin starts from the prompt and when I changed some settings in
zapctl then ./startzap also worked. That is the zap process shows on ps, but
I'm not able to connect to the server with any browsers.

Now - whats wrong?

My guess is that the hardest part of such an undertaking would be to
convert Jim's extensions to Java/JPython.  Specifically, ExtensionClasses
and Acquisition are probably the hardest to do (I believe many of the
others are just fast implementations of Python versions).  Jim Hugunin
mentioned that he had thought a bit about ExtensionClasses, but I'm not
sure how far that went. The efficient POS and other extensions are also
clearly a significant undertaking, but maybe not as hard to translate.

However, I don't see it happening until someone has a commercial
motivation to invest the large required number of hours into it.

Zope relies on a lot of code in C as well as Python, so I doubt you'll see
Zope on JPython anytime soon.

However, ZPublisher (Zope's ORB) could be made to work with JPython without
too much trouble. In fact a while ago I tried this and succeeded, though it
was quite slow. The main issue is that ZPublisher uses 'regex' while
JPython uses 're'.

FWIW, my shop is running Sybase OpenClient 11.1.1 on IRIX 6.2, 6.4, and 6.5
on a Challenge/S, O2000, and Challenge/L, respectively.  I successfully
installed ZSybaseDA into Zope on the Challenge/S; haven't tried on any others.

Also FWIW, I have experienced nothing but problems getting PCGI to work on
any of the IRIX platforms; your mileage may vary.

(Coincidentally, the company I work for owns a couple hundred SGI boxes and
we keep our inventory of them in a ZPublisher app...  it's on mySQL,
though, not Sybase.  OTOH, our request tracking system is a
ZPublisher-on-Sybase app.)

Does this include the latest version of PCGI?  

FWIW, I'm willing to work with anyone getting PCGI 
to work on their platform of choice.

Folks:

Error message when trying to send e-mail from a Zope-generated web-form. I
did RTFM at http://www.zope.org/Documentation/HowTo/MailForm and I still
get the following error message:

Both sendmail and DNS are properly installed since I was able to send

I'm no Zope expert, so any suggestions appreciated.

The last version I tried was the one distributed with Zope 1.9.0 - it
exhibited the same fail-on-process startup behavior as previous versions,
so I went to ZServer as a stopgap until I could complete a FastCGI
replacement.  I'm now using FastCGI, so it's no longer an issue.

Actually, some time ago I sent Jim some code that was a regex mockup
implemented using re.  It didn't do all of regex, but enough to make
DocumentTemplate work.

At first blush, I'd say that the host you've defined as the target of 
mailhost does not accept or is not running a mailer on port 25.

Are you certain you have mailhost setup correctly?

I Followed the URL backward from:
Michel Pelletier's "You've Not Mail !!!"  Page,  
http://starship.python.net:9673/crew/furtrapper/NotMail

Hey, this is neat,  starship.python.net must be 
running ZOPE because the port is "9673" !!!  
therefore going to:
http://starship.python.net:9673
"Welcome to Zope at the Starship Python!"

So, to join the crew of the Starship and get your own
ZOPE pages on the internet requires PSA membership.
One can join now and pay for a half year $50/yr 
or $25 for half.  Membership wouldn't be effective
until April 1st (a Foolish day!) 

So, Zope is cool and so is Python.  I am considering
joining PSA on the strength of Zope and Elegance
of Python but I'm concerned that Python doesn't seem 
to have much "MindShare" like Java or Perl.

Ok so our local Borders has only one book on Python:
"Programming Python" by Mark Lutz (Pub: O'Reilly)
A great book that is dated 1996.  The shelves are
full of books on Java and there are quite a few Perl books.

What is the BIG PICTURE here?  Is Python so good
that lot of programming tomes are unnecessary?

Why is there so little press on Python and so much
for the less Elegant and slower Java?

Is Python a "secret weapon"?  If so, the secret should
get out to the world so Python gets more mind share
and doesn't develop cobwebs.

***So, where are the rabid Python fans?***
Yes, a bunch of them are on the ZOPE list.

Great answers to these questions will only help ZOPE!

I'm using pcgi from 1.9.0 (README says it's 2.0a4) under Irix 5.3 (yes, I
know, I keep bugging the sysadmin to upgrade :) ).  Occaisionally, pcgi fails
to start up, logging "Interrupted system call  (116) unable to connect, fd=4".
I also had the same problem when using FastCGI w/ threads: the application
would hang and I'd get an "interrupted system call" in the log after a while.
I have never experienced either of these problems under linux, so might this
be an Irix problem?  I remember that Philip also suspected an Irix
"sockets-and-threads-don't-mix" problem, which appears to be what I have
experienced as well.  Philip, is theaded FastCGI still broken on Irix?

As a language qua language, Python is so good in design
and implementation that it has few dark mysteries that
require a lot of documentation to explain.

The existing Python books are quite good, with at
least 4 more in the works.  More Python books are 
necessary to explain things like Win32/COM programming, 
for instance, than the language itself.  Perl has
lots of books, because for the past 2 years, almost
anything that offered to make Perl programming easy
was given shelf space.  Java has lots of books
because almost everything in Java has to be written
in Java, and the Java libraries have been a moving
target for so long.

More important than the number of books (how many
Perl books do you really need, after the Camel?) is
the level of support/platforms in the Python community,
which is quite high.  It will probably never attain 
the proportion of mindshare that Perl or Java has,
but is has critical mass, and a lot of compentent people
who contribute code.  Too many companies now rely upon 
Python as their core development language for it to go 
away anytime soon.

More importantly:  You'll spend more time learning about
the eccentricities of whatever your environment demands,
be it Unix, Windows, web servers, CE devices, COM, Tk, etc.
than learning the language itself.  This is Python's 
great (and under-reported) strength.

Hi all,

This is probably more of a newbie Linux question than a newbie Zope
question, but I'm going to ask it here anyway:

I would like to connect Zope to a database, so I have setup both
PostgreSQL and MySQL. My reading tells me that MySQL is probably the
better choice as a web backend (Any comments from those of you more
knowledgable than I would be appreciated!) So I downloaded the MySQL
source, compiled, installed and tested it. It looks like I did it right.
I then downloaded the ZMySQLDA from the Zope site.

I have followed the directions--I think, but get the following error
when trying to do the initial make:

[tjg@puddleglum src]$ make -f Makefile.pre.in boot
rm -f *.o *~

FYI:  I know of at least 5 other Python-related book projects in various
stages of development.  One of those should be hitting those same shelves
in April sometime (http://www.oreilly.com/catalog/lpython/).  It even
mentions Zope in a couple of places.  [Disclosure: I'm a coauthor of said

Python is certainly easier to learn than some other languages.

Mostly, because Java is backed by a multibillion dollar company with lots
of $$'s for public relations.

ObZope: I'm having a hard time with the 'access' file -- it looks as if my

A perfectly reasonable suggestion - and one that I have made many times myself!
<g>

I did, in fact, RTFM - but the FM makes absolutely zero mention of anything
"leverish", to adopt a seemingly Zopish mode of Englishish. ;-)  I followed your
link given in another message, and realised that what I had been reading about in
terms of Product Distributions was (I think) what you refer to as the "Lever".

IAC, I followed the instructions given, and when it didn't work I went back, and
worked my way through the Product Tutorial exercise - excellent!   The POLL
product works fine!  But the levered faq product .DAT file apparently failed to
unpickle - as described by others in this thread.  My product management screen
shows the FAQ product as installed, but the actual product directory still has
just the three files from the tarball.  In my case, however, it is on a Linux ZAP
system - so the problem is not confined to Win32 as others have conjectured.

Hope this helps, and apologies for the lack of specifics in my previous post.
Can we please have the term "lever" clarified and documented a little better.

My experience was MySQL had better support for large
streams of text data and blobs than PostgreSQL.  However,
MySQL also lacks support for transactions.  This probably
contributes to its speed, which in turn makes it popular
for web apps.

THis is completely correct.  The access file is ONLY for the

I assumed that the .DAT file contained all the component DTML and PY scripts etc
and that these would be expanded into the Product's home directory somehow.  Is
this not the case?  Is the .DAT distribution a way of  distributing the objects
without the source ? (more Cathedral than Bazaar)

No - but it does show up in the installed products control panel.

As stated before, Zope 1.10.2 running on ZAP-Linux.

Note that you could, pretty easily, write a new UserFolder type object
which worked off an access file. Could be useful for people who are generating
the access file from an /etc/passwd file, or whatever.

You could also skip the generation step and write a UserFolder which
works off of /etc/passwd.  In fact, NotMail could use this as a helper
too.

Subject: [Zope] ZServer and MSIE (long & detailed)
Message-ID: <l03130300b30112942a29@[206.40.158.77]>

Has anyone else experienced a problem getting Explorer to connect with
Zserver?  I have no problem with any version of Navigator but MSIE 3.01 and
4.0 and 4.5 for both Mac and Windows throw up an error box claiming an
"error with Explorer's internet extensions has failed".

Very baffling, I can connect just fine via telnet using the following
requests, ZServer (medusa) returns a proper html page.

Requests sent:

GET / HTTP/1.0
Connection: Keep-Alive
Host: www.fishwrapper.com
Accept: image/gif, image/jpeg, */*

response recieved:

blah, blah, blah.....

(note the difference in the sent host and recieved host, the host arg in
the start script sets the host for the ftp server, not the webserver...)

I can see nothing in the responses that would cause MSIE to fail, note this
has been tested from four different PC's on three different ip's, including
a local connection from my Lan.

Strangly enough I did a stream capture and hit my server and the startship
server (also running ZServer) and the two responses differ even though the
requests were from the same browser on the same connection.

Do starships ZServer and mine differ?

My  http_server.py  script carries RC_ID of:
 "v 1.4 1999/01/18 22:44:49 amos"  I downloaded a fresh copy of ZServer
when I grabbed the newest copy of Zope.

Any clues? I've been documenting and testing everything I could think of,
I'd report a bug but it seems MSIE works with the Starship server, so I
think it's not a bug so much as something wrong on my end?

Slackware V 3.6
Zope v 1.10.2
ZServer 1.0a2

I understand the security problems inherent in ExternalMethods; unfortunately,
without them, Zope is merely an "also-ran" in the web applicaton race, from my
perspective.  DTML in isolation is not an "ASP-killer."

I'm CC'ing the Zope list, in hopes that someone there can either allay or slay
our fears.

It seems to me that the security problem is that ExternalMethods can get access
to "sibling objects" of the object on which they are invoked, right?  I mean, if
we could make the siblings inaccessible, and acquired properties read-only, then
we should be ok, no?  Ugh, I don't grok acquisition well enough to tackle that
myself, I fear.

from inside DTML, is there a way to say "don't process any further DTML,
just return this to the user"?

What I'm looking at is a small DTML snippet that gets included at the
top of a number of pages, and looks for a particular variable to be
set. If it's not set, it should just display a small "please enter a
widget name" form which submits back to the same page, and not display 
the rest of the page at all.

will just doing a RESPONSE.redirect() automatically do this?

Message-ID: <129.78.8.1.126.8280.920360936.257.8891>

I'm making a Zope "Product" for managing and creating student surveys
(which I hope to contribute via zope.org) but I'm having trouble with a
couple of techniques:

1.	How does one enable a dtml file that is instantiated as in
		my_dtml = HTMLFile('my', globals())
	available for editing in the products' management screen?

	There's probably more to this - as at the moment the management
	screen goes straight to the "index_html" form as with the "Poll"
	Product.

2.	What's the approved way to catch database errors in methods?

	I'm creating tables on the fly, and need to check if the table
	exists before trying to create it. (I'd use a "tables" method if
	all the database interfaces supported it. I'd also use a try/except
	but the database objects have different names for their exceptions.)

Message-ID: <8174B1EE3D2CD21180960000F8056723CFB321@telisnt1020.is.tel.co.jp>

Hi All!

First off, I'd like to thank Digital Creations for an excellent (and
really fun) product. 

I'm building a prototype web site interface for a database where I
work using Zope 1.10.2 and the ZOracleDA product and have a some
questions. 

1. When trying to do a join (a lazy query, I know) like:

   select a.*, b.*
   from tablea a, tableb b
   where a.b_id=a.id

   Both tables have an ID column so Zope raises a 'ValueError'
   exception with the  message 'Duplicate column name, ID'.
   I wonder if instead of raising an exception something like the 
   following could be done?

   A diff of Shared/DC/ZRDB/Results.py:

120,131c120
<                 #raise ValueError, 'Duplicate column name, %s' % name
<
<                 #instead of error, append an extension to
<                 #create a unique name
<                 tempname=name
<                 nameext=1
<                 while schema.has_key(name):
<                     name=tempname+'_'+str(nameext)
<                     nameext=nameext+1
<
<                 #update with newly created name
<                 item['name']=name
---
>                 raise ValueError, 'Duplicate column name, %s' % name


   I tested this some and it seems to work. Are there any problems
   that could be caused by doing this?

2. I'll post the other questions separately because they are
unrelated. 


   TIA!,

The .DAT file only contains information to be added to the Object Database. It
won't be expanded into files onto your harddisk.

Zope stores all instances of classes in it's object databse, via a process
called 'pickling'. This, in simple terms, means that all data stored in an
object is turned into one stream of data that can be stored in a file.

As a 'Levered' product contains nothing but instances of classes, not the
classes themselves, it suffices to distribute only the compressed pickled
contents of the product. The source for the used classes you allready have (at
least with the FAQ you do, it uses only DTML Methods and Folders), and the DTML
scripts can be viewed in Zope, so you do get all the source.

The objects that make up the product should normally be automaticly
decompressed and imported into Zope, but the decrompressing seems to be
failing.

val wasn't set to None and so the null attribute never got used. Since
None is false, the above should be OK. (It seems to work for me,
anyway :^)

That works fine if it's all one big DTML method. But what if you have
a series of pages which each have
<!--#var check_widget_settings--> at the top.
inside check_widget_settings I want to be able to say "if this, then
enough. don't return back to the enclosing objects, just send what
you have now." kinda like a DTML exception :)

Subject: [Zope] AUTHENTICATED_USER
Message-ID: <153C1D93564@sahara.cspt.es>

Does anyone have any more information on AUTHENTICATED_USER? We saw a while 
back that it has properties (AUTHENTICATED_USER.has_role(['Manager', 
'Editor'])). I would like to be able to get the user name, and use that to 
index simple files for users. Is there something like 
AUTHENTICATED_USER['UserName']?? This is essentially the information that is 
returned if you try <!--#var AUTHENTICATED_USER-->. However, if you try 
something like <!--#if "AUTHENTICATED_USER in objectIds()"-->, it does not 
work.

The only way I have been able to use this information so far is to put 
<INPUT TYPE=hidden name=userID value="<!--#var AUTHENTICATED_USER-->">
in a form, and pass it in a REQUEST to another page. But I want to be able to 
get this information directly. I have even tried REQUEST.set('myUser', 
AUTHENTICATED_USER) inthe header, but this has the same problem 
(unsurprisingly) as AUTHENTICATED_USER itself.

Any hints?

Thanks,

JP

I want to call a function I have made, with arguments.

1) is there any way to call it direct, complete with module name? It would mean
getting Zope to import that module.

2) I know I can put it in an external metod and use <!--var mymethod--> but it
needs arguments, so I'll need to set and re-set the same DTML-namespace

AUTHENTICATED_USER itself is an object -- the reason
<!--#var AUTHENTICATED_USER--> gives you the user name
is that it effectively does an str() on the user object.

To work with the user name directly, you can use the
getUserName() method of the user object:

<!--#if "AUTHENTICATED_USER.getUserName() in objectIds()"-->

I am not sure I understand your problem. Default arguments can be given in
the definition of the function. If you need to pass a variable in an
external method you can just do
<!--# var "mymethod(myvariable)" -->
Additionally the self argument in the external method definition is
replaced by the object (or containing folder) that calls the method so you
have access to the namespace of the object through self.

Where is your function located? Is it an external method? In this
case imports in the method's file work fine, but only inside Zope's
search path (practically, the installation path and lib subdirectory).
A good place to put your modules and packages is the 
lib//shared/<your company> dir.

Use <!--#var expr="AUTHENTICATED_USER.getUserName()"-->

More hints linke this can be found in the User.py file in your
lib/python/AccessControl directory.

The following functions could be usefull:

getUserName(self): Return the username of a user
getRoles(self): Return the list of roles assigned to a user. 
getDomains(self): Return the list of domain restrictions for a user
allowed(self, parent, roles=None): Check wether the user has access to parent
hasRole(self, parent, roles=None): Check wether the user has the specified
roles
has_role(self, roles): Check wether the user has the specified roles

allowed & hasRole are one and the same. When called with parent=None, it
just returns wether the user has the named roles. has_role also checks for
roles, but doesn't automatically include the Anonymous role. So,
hasRole(None, 'Anonymous') always returns true, but has_role('Anonymous')
returns false for every user that has been authenticated.

Note that AUTHENTICATED_USER is always defined, also for anonymous access.

Here is a little example of what you could do with these functions:

<!--#comment-->Display user info<!--#/comment-->
You are the user named <!--#var expr="AUTHENTICATED_USER.getUserName()"-->.<P>

<!--#if "AUTHENTICATED_USER.getRoles()"-->
  You have the following roles:

  <!--#in "AUTHENTICATED_USER.getRoles()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You have no roles defined.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.getDomains()"-->
  You are allowed to log in from the following domains:

  <!--#in "AUTHENTICATED_USER.getDomains()"-->
    <LI><!--#var sequence-item-->
  <!--#/in-->
<!--#else-->
  You can log in from any domain.
<!--#/if-->
<P>

<!--#if "AUTHENTICATED_USER.has_role(['Manager'])"-->
You have the 'Manager' role.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['Anonymous'])"-->
You have the 'Anonymous' role. You are therefore an anonymous user.<BR>
<!--#/if-->

<!--#if "AUTHENTICATED_USER.has_role(['nonexistent'])"-->
You have the 'nonexistent' role.<BR>
<!--#/if-->
<!--#var standard_html_footer-->

The last call to has_role is to show that the user defined in the 'access'
file in the root folder of your Zope installation, has ALL roles, including
non-existent ones. And even more interesting, the call to getRoles() will
get you 'manage', a misspelled version of the 'Manager' role. This is
probably the only way to reliably recognize the superuser.

Well, it's actually deeper than that. You are correct in saying
that DTML alone is not an ASP-killer. Consider the similarities
between Zope and, for example, ASP/COM (though the same holds true
for practically any other system as well):

ASP lets you use the services provided by (COM) objects, which may 
be provided by the server or provided independently. I'm sure that
MS tries to make the server-provided objects fairly safe, but there
is _nothing_ stopping a programmer from writing and installing a COM
object with an evil() method that wipes out your C: drive, except the
fact that presumably the sysadmin exercises some control over making
these independent services available.

The same holds true for Zope (and any other app server out there). 
Like ASP/COM, External Methods give you the ability to provide more 
powerful services for use by your application. It also gives you 
exactly the same problems (though I'm sure that evil() method could 
be developed in a quarter of the time in Python :)

Basically, with power comes responsibility, and I can't really imagine
any system that could _safely_ allow possibly-untrusted people to write
(basically) arbitrary code. It's not even really a matter of what
services
are or are not available to those people. I'm sure that many, many hours

and much brain-power went into the design of Java's security mechanisms.
Even so, if I were a web site manager I still couldn't let untrusted
users write their own arbitrary java code to run in my web or app
server.
Even after I had figured out a way to wall off every service I could
think
of that could possibly be harmful, the user could still probably just do
the Java equivalent of:

  while 1:
    pass

Zope DTML goes to a good deal of trouble to minimize these problems 
in DTML itself, and we would certainly consider any concrete ideas
on how to make External Methods safer. Can you give me some examples
of other app servers that you feel deal with safety of external 
services in a better way? I'd be happy to do some looking into how
others are dealing with this.

Make your Product a Folderoid (zopespeak for a Folder Object) that
contains it's own user interface which the manager can edit.  Your
__init__ function initially loads the documents off disk into the
Folder.  Confera and NotMail both do this (Confera does it a little

There absolutely does need to be an "unprotected mode" available though - the
system designers might *need* it to do scary destructive things like deleting
files. Zope should not get in the way.

believe a FAQ on the Zope site is neccessary.

Do the folks at digital creations have time to set it up?

This is an excellent post.  I want to add that _getPassword() is a handy
function also if you want to use your Zope user to authenticate into an
external system, like POP3 or IMAP.

Message-ID: <36DC0962.7996940D@oi42.kwu.siemens.de>

Hi,
The followowing problem seems very fundamental to me.
I already did a post to this group to this topic and I got the following
answer:

On Wed, 13 Jan 1999, Dr. Armin Tschammer wrote:

The "print" goes directly to the webserver, which confused it: it
expects
HTTP headers like "HTTP/1.0 200 Okay".

The "return" sends your data to *Zope*, which then does the header stuff

for you.  Same with cookies, content-type, etc.

Summary: dont use 'print', or redirect stdout to a log file.


Now the problem is deeper, what shall I do when I am import C++ Modules
in Python ( extending Python),
and that modules are writing to the stdout via "cout" or "printf", I
have no influence to that.


If I change the stdout via "freopen( "file, "wr", stdout )" or stuff
like that, I have no chance to switch back
to the *real* stdout  ( look at the c-faq of comp.lang.c ), and I *have
to* switch back because of the cgi-mechnism,
which uses ZPublisher.
The only the chance to handle stuff like that is to work with two
processes in the Zopemechanism.
A Zopeserver which tells the Zope Client to start a pythonfunction. Now
all stdout happens on the
client and the server listen for a string on a socket ( or something
similar ). Now when
the server gets the string it does all necessary wrapping ( content-type
and so on ), and
send it to the Xserver via its stdout.

Or is there a less complicate solution ?



 Thanks in advance

   Armin

That's unfortunate, but we understand.  Getting *anything* to work with
Apache's mod_rewrite module is quite a chore.  It doesn't help that
distributions like RedHat 5.2 ship it in a broken way, then people blame
us for it, then we track down a problem that is completely outside Zope.

Did you follow the recommendations to start with the built-in webserver
before trying integrate with Apache?  If so, did that work?

I believe this is allready under construction:
http://www.zope.org/Community/Services

By far from incomplete, but it is the right direction. I think Amos' FAQ tool
should be utilized there somewhere, and maybe some people from this list
willing to help out DC should fill it in, because it looks like Ken Manheimer
(who has been charged with community communications) allready seems overloaded.

What about

select *
    from tablea a, tableb b
    where a.b_id=a.id


Wouldn't this give you vars called a.id and b.id?

Hmmm... I bet Zope won't like that.

It occurs to me that a DTML document could contain this in a transparent
sendmail form, assuming there is already a handy Mailhost set up, to capture
and mail off the password of anyone browsing the page...

Not really -- you can't access _getPassword() from DTML. You would
have to write an external method to do that (which implies that
you have access to the filesystem, and could get the passwords
anyway if you wanted them that bad...)

While we are on the subject of AUTHENTICATED_USER, I would like my users to
be able to "logout" so that they then become anonymous again.

Any ideas?

I have seen this on Dejanews. It would be useful so that authorized users
don't leave themselves logged in if they don't quit Netscape.

	Is there any chance that you're trying to do something
	like:

	select *
	from a, b
	where a.b_id = b.id
                       ^

More generally speaking, we should be organizing the Zope documentation
project. There was word of it before, but haven't heard much on it
recently. In fact, the messages that I can find in my mailbox on it is
people saying we should start such a project :). I'd obviously be very
useful.

As an example: I myself have sent some (obscure) questions to the list
the week before last, and have only managed to receive an answer that
confused me more (I welcomed the answer though, of course!). I sent more
questions and observations last week, but haven't received answers yet
(perhaps it's because I'm doing something fundamentally wrong with Zope
but I'd like to hear it if that's so). Of course I'd like to see my
questions answered.

A FAQ would help filter out all the less obscure questions so that my
obscure questions might get answers. :)

So, the Zope Communication Project (hereby started if it doesn't exist
yet, this is open source after all :) should make its first priority to
create a fairly exhaustive FAQ. I currently have some time to invest in
the ZDP (he said, tempting fate; work's slow right now, but this can
change quickly).

Anyway, I'll help. If only with the *questions* side of the FAQ,
perhaps, but I can help. :)

Initial Plan of Action for the ZDP:

- Produce a fairly exhaustive FAQ, mining the mailing list for good
questions and answers.

- Organize the ZDP itself. :)

Regards,

Martijn

Subject: [Zope] [ZDP] Announcing the Zope Documentation Project
Message-ID: <36DC17B8.7F5CFF6A@pop.vet.uu.nl>

Hi there,

Hereby I announce in absolute adhoc anarchistic fashion the Zope
Documentation Project. The Zope Documentation Project aims to generate
documention on anything Zope.

The Zope Documentation Project needs people who wants to help. It needs
these people to get organized.

To get focused, I propose the ZDP's initial project is to provide FAQs
on various Zope topics. We can mine the mailing list for good questions
and answers.

The ZDP asks everybody to contribute. Right now we need everything. :)
We need questions and answers, and we need to categorize these in
separate FAQ sections. We need Zope webspace somewhere to put up the
FAQ, I assume using the FAQ product. We need to develop the FAQ product
further, if necessary. We need whatever you can think of.

The prime mean of communications for the ZDP is the Zope mailing list,
until further notice. I suggest that to keep the mailing list somewhat
organized we prepend our mailing list subjects with '[ZDP]'. If somebody
has a better way, we'll do it a better way.

Note that while I'm sending out this message, I'm not anything official.
I'm just attempting to get the ball rolling.

*nudges the ball*

Regards,

Martijn

Could it be a 1.5.1 vs 1.5.2b2 thing?  I have 1.5.1 and it failed for me.
Is the zlib.pyd in 1.5.2 based on a newer version of the zlib library that
may not be forward compatible?

I don't have any experience with Zope or even Python, but am I right
in guessing that this looks like a problem with the python binary and
not with Zope?  Any ideas to precisely what the problem might be?

python is v1.5.1.

I finally got it working - just couldn't get it off my mind. Was kinda
mindblowing the whole thing but finally - YES I MADE IT! :)

What I did was to jump off the mod_rewrite thing and try let apache handle
the authentication all together. At first I didn't know of the htpasswd
binary (stupid as I am) so things didn't work at first. Then htpasswd lit my
eyes - did the 'htpasswd -c' thing and ended up with a working AuthUserFile.
Now the trick was to configure the damned thing in httpd.conf - this worked
out ok:

"""
ScriptAlias /cgi-bin/ "/usr/local/apache/cgi-bin/"

<Directory "/usr/local/apache/cgi-bin">
	AllowOverride None
	Options FollowSymLinks ExecCGI
	Order allow, deny
	Allow from all
</Directory>

AddHandler cgi-script .cgi

<Location /cgi-bin/Zope/>

Message-ID: <613145F79272D211914B0020AFF64019069109@GANDALF>

Hello everyone:

Some of you may know that many moons ago we (Brian) developed a plug-in
for Netscape Enterprise Server (ES) 2.x (and FastTrack -- based on the
same libraries) that addressed Netscape's nasty habit of removing
authenticated_user information from the environment before calling CGI
apps.  Obviously, this has a deleterious effect on interesting zope
applications.

Fortunately (?), we are up to our armpits in projects and initiatives.
As a result, we need someone to do a bit of work to upgrade the plug-in
from ES 2.x to ES 3.5.x.  I can provide the following files from our 2.x
incarnation:

o  plug-in source code
o  obj.conf
o  magnus.conf

The source code is only 153 lines of generously formatted C (w/lots of
defs) so I'm hopeful that this isn't a HUGE task.  I'm interested in
hearing quotes from people in the community that have experience with
the NSAPI and would, for a reasonable fee, develop, compile (Solaris 2.6
and NT4) and test an upgraded plug-in.  The work would be contributed
back under the ZPL.

Naturally, I'd also entertain offers from people to do this for free!
:^)

--Rob

P.S. - I KNOW there are some NSAPI wizards out there so don't be shy!

How about Mr. Creosote. This is a wonderful little utility from Jeff
Bauer. It basically an example implementation of socket datagrams... ie.
it lets you print out via a socket to a little server program. Its great
for debugging Zope/Bobo apps.

Here's Mr. Creosote's web page for more info...

Please don't ge me wrong:  I _like_ ExternalMethod / Product as a way to extend
Zope.  My comment is in the context of not (currently) being able to add
ExternalMethods to my Zope demesne on starship, given the (quite legitimate)
security concerns of the Zopemeister.

I looked at the ExternalMethod source last night a bit:  the actual method
execution is done via an apply() call, after loading and compiling the code for
the function.  We might be able to come up with an alternate product which used
a carefully tuned rexec() (Bastion?  I plead ignorance), operating on Python
code stored in the Zbase itself.

The particulars of my case are that the control structures of DTML are not quite
powerful enough to accomplish my task;  of course, strengthening them, even in a
"sandbox" model, still leaves open the possibility for buggy/malicious code to
do ugly things (like your example below).

Any Turing machine can do "while 1: pass", so no sufficiently general syntax is
"safe" from this attack.

Actually, the possibility which seemed most interesting was Doug Wyatt's
suggestion of "federating" a set of independent Zbases under one (at least
apparently one) server.  Then any damage my ExternalMethod did would be to the
Zbase would be on my own head, at least.  If that server were actually a process
running as me, then standard system security procedures should probably be fine.

You might want to consider switching to one of the official binary kits
available from MySQL's homepage. MySQL is notoriously picky about how it

Looks like you didn't install the development libraries for python
(python-devel or python-dev).

This was an idea I'd proffered, but honestly haven't looked at enough
yet to know whether it would work... it SHOULD work, but it might
require some modifications to the aquisition code, but I've not looked
neough yet.

Well, it might help if you offered what control strucuture you need, we
might be able to come up wit han interim solution.

TO me this is just a hack to get around it near term, and doesn't fix
the problem.  Also if you have 100 users, do you have 100 instances of
zope running under 1 ZServer?  That sounds like a true administrative
nightmare...  And substantial overkill.

Ok, the "teeth-cutting" example I am trying to implement generates math-facts
problems for my five year old.  In Python, two trivial functions:


I _think_ this one is easy in DTML:

    def problem( max_term, operators ) :
        """ Generate a single math-fact problem whose terms are within
            range( max_term + 1 ), using one of the supplied operators.
        """
        lhs = random.randrange( max_term + 1 )
        rhs = random.randrange( max_term + 1 )
        operation = operators[ random.randrange( len( operators ) ) ]
        return ( lhs, operation, rhs )

But not this one:

    def gen_problem( max_term, operators ) :
        """ Generate a math-fact problem whose terms and results are all within
            range( max_term ), using the supplied operators.
        """

        while 1 : # Arbitrary looping! (could benefit from
                  #   the dreaded assignment-in-conditional :)

            probStr = "%d %s %d" % problem( max_term, operators )
            result = eval( probStr )

            if 0 <= result and result <= max_term :
                return probStr

And of course, the DTML syntax for something like this is going to be ugly.

One instance per "sandbox", not one per user (although on starship this is a
distinction without a difference).  The "content manager only" applications will
do fine in a single Zope instance, as now.

In my experience many situations where external methods are needed do not
require access to the Zope data tree, like the math test example you
presented. 

One approach is to use a second server that does XML-RPC (Fredrik Lundh
has already written a client and a simple server) and set an
account/folder where everybody can upload their scripts and access them
through XML-RPC calls from their Zope environment. I suppose we can write
a product that provides the client site of the XML-RPC based on Fredrik's
implementation. As for the server site Jim once mentioned that the support
should go in ZPublisher but initially a simple server based on python
standard libraries will be adequate. Or use the newly released asyncore
libs though I suspect a multithreading server will be better in this
situation.

If however one requires access to the 'self' argument of an external
method such an approach will not be adequate. Usually though one can
collect the relevant parameters by using DTML calls and send them to the
XML-RPC server for processing.

Message-ID: <016401be64f3$2e5b79d0$8725d2d1@rogue.jenkon-dev.com>

I have a folder with various boolean properties associated with it which are
accessed by the dtml docs as flags for enabling or disabling content.  Turn
off the flag and a chunk of the page goes away when it is next viewed.  This
works great, but I would like to associate that behaviour with the security
attributes.  In other words, when somebody in the Anonymous role is viewing
objects in the folder the properties should be unset, but when users in the
manager (or some other specific role) view the pages then the properties
should be set and those parts of the pages are activated.

How can this be done?

Thank you, Martijn, you've made my day!  This is extremely cool.  

As you might expect, here at digicool we're yearning to produce more and
better documentation, and, as with other things, we want to have more
time and energy to do it than we do.  This kind of effort from you, and
from anyone else who can help, is *severely* appreciated.  I know i'll

can, how else can digicool help?  Some thoughts, below...

Some thoughts:

 - We would be happy to provide a mailing list or two for you all

 - If it makes sense (logistically, for us as well as for you), we could
host 
   the FAQ stuff or whatever on zope.org.  This we'll have to discuss -
both
   what all might want, and what we can safely and effectively do...

(I've been thinking about requirements for a collaborative FAQ
mechanism, which can be tricky if you want it to be available for
contribution to the community in general, yet still remain organized
enough for people to find what they're seeking.  An interesting
problem...)

For those interested changing the "chunks=1" to "chunks=0" in

Zope's, I don't consider this a bug with ZServer but with MSIE as this also

Hm - this indicates you've upgraded your Python since the module
_pg was compiled (postgres?)
It's not the cause of the following error, but it is something you might
want to fix, anyway.

The error looks to be caused by ZopeHTTPServer not handling a client
aborting the connection. Looking into the code, at around line 240 of
ZopeHTTPServer/ZopeHTTPServer.py, the write() method of ResponseWriter
should probably trap IOError and ignore it. 
Something like wrapping the two calls to write() in the write method
like
  try:
      write....
  except IOError:
      pass

would be a blunt fix to it. I don't think DC want to continue to 
support ZopeHTTPServer, tho. You might want to try to upgrade to ZServer,
instead.

No, because from DTML you can't call methods starting with an underscore. This
was actually the reason I didn't include this in my overview.

You can still use it in en external method, I know. But then again, I can do a
heck of a lot more bad things in external methods.

This is very hard to do from the serverside. I can force a new login, but I
cannot stop a browser from authenticating itself at every request, therefore
effectivly becoming anonymous.

Problem is more that HTTP is stateless, a user is not 'still logged in', but it
autenticates itself at every request. Only when the server says that the
authentication is incorrect, does the browser ask for the username and
password.

What you could do, is write your own UserFolder/User combo, that stores a
last-access time on the User object, and checks for this every time a user is
authenticated. If the difference is greater than, say 15 minutes, you force a
reauthentication by raising a permission denied.

I tried playing with this once upon a time, but I found that the stupid
browser still cached the original result and would continue to use it after
the failed login/relogin combination. Most frustrating.

Subject: [Zope] need help with IIS/ODBC
Message-ID: <3.0.6.32.19990304173128.008fc510@hito.eccosys.com>

As a novice (who's loving Zope!) I'm having a terrible time trying to get
Zope1.10.2 on NT with IIS to connect to MS SQL with a Z ODBC connection.
Previously I had no problem getting Zope 1.9/ZopeHTTPServer to connect to
MS SQL via Z ODBC. 

Recently I upgraded to 1.10.2 without a hitch, and was able to run it with
IIS 4.0 after putting the (PCGI executable?) MYZOPE.exe in
/InetPub/scripts/ and turning off in IIS both Basic Authentication and NT
Challenge/Response as I read here in the list.

My problem now is that when I try to open my db connection (exactly the
same connection that was working with 1.9 & ZopeHTTPServer) I get the
following error from IIS:

>HTTP Error 400
>400 Bad Request
>Due to malformed syntax, the request could not be understood by 
>the server. The client should not repeat the request without modifications.

In trying to figure out what's going on I've noticed a couple things.
First, and I think most illustrative, if I try to add a new Z ODBC
connection, none of my ODBC sources are showing up in the available list
(except the default 'LocalServer, SQL Server') - whereas if I run my 1.9
Zope with ZopeHTTPServer all my ODBC connections show up just fine.

Also, running my new 1.10.2 Zope/IIS with the faulty db connection side by
side with the functioning 1.9/ZopeHTTPServer, I printed our the environment
variables of both and noticed some differences - USERPROFILE's are Default
User vs. Administrator, and the 1.9/ZopeHTTPServer contains variables not
contained in the 1.10.2/IIS environ: HOMEPATH, TEMP, USERNAME, HOMEDRIVE,
USERDOMAIN, PROMPT, LOGONSERVER, TMP. I attempted to set at least
USERDOMAIN in the 1.10.2/IIS environ, with no luck.

I've read all the posts from the list that I could find dealing with IIS
and ODBC, but couldn't find anything with info on this type of trouble.
Have I made a boneheaded mistake and started to look in the wrong places
for the fix? Any help/info/pointers would be hugely appreciated as I
continue to bang my head on my keyboard hoping that I'll soon clear this
hurdle and get back to having fun with Zope!

Thanks!

Jay

You could, using AUTHENTICATED_USER.has_role() and manage_changeProperties(). I
think it will be better if you completely skip the property setting though..

You could just show content using
<!--#if ATHENTICATED_USER.has_role(['Anonymous'])-->
        Content _only_ for the Anonymous user
<!--#/if-->
<!--#if ATHENTICATED_USER.has_role(['Manager'])-->
        Content for users with the Manager role.
<!--#/if-->

This way you don't accidently let any properties float around, causing content
to be shown to the wrong people.

You can use the #in tag's grouping features for this. If you use GROUP BY in
your SELECT statement, or use the appropriate sorting, you can use the
following DTML code to get the desired output, assuming the column names are
the same as in your example:

<!--#in MySQLMethod sort=field2-->
<!--#if first-field2-->
    <!--#var field2 fmt="DayOfWeek"-->, 
    <!--#var field2 fmt="Month"-->
    <!--#var field2 fmt="day"--><BR>
    <BLOCKQUOTE>
<!--#/if-->

<!--#var field1-->

<!--#if last-field2-->
    </BLOCKQUOTE>
<!--#/if-->

<!--#else-->
Sorry, no colors in your query.
<!--#/in-->

The variables first-xxx and last-xxx are set whenever the field with name xxx
starts/ends in a sequence. For more information on this, read the Zope DTML
User's Guide (http://www.zope.org/Documentation/Guides/DTML

Subject: [Zope] ZPublisher and creating children
Message-ID: <36DCF9B5.97A62E66@acriter.com>

Hi,

I'm using ZPublisher+DocumentTemplate+BoboPOS in a cgi environment,
because that's all I need (and can use on my ISP's box). In the couple
of things I've developed so far, a pattern has emerged that disturbs me:
if you have a container object, when adding a child, the whole add thing
is done in the parent. IIIRC, I fetched this design from the (Bobo)
Trinkets example when I started:

class Container....
     add = HTMLFile(....)
     def do_add(self, childattrone, childattrtwo, childattrthree):
        d = self._items
        d[childattrone] = Child(childattrone, childattrtwo,
childattrthree)
        self._items = d

class Child...

     def __init__(self, childattrone, childattrtwo, childattrthree):
         ....

     edit = HTMLFile(....)
     def do_edit(self, childattrone, childattrtwo, childattrthree):
           ....

The Container, IMHO, "knows" too much about the Child in this case, and
it's hard to modify the attribute set of the Child class. Am I doing
something wrong? Is there a design pattern here I'm not aware of?

Regards,

Cees

These are good ideas (and thanks Chris for the offer!), but Ken

It was getting obvious that this was so. You guys all did a great job,
and still are doing a great job, but the volume of questions and
documention requests has exploded in the mean time. Which is great, in
fact, of course, as it shows people are interested.

This would be great! We probably don't want to be spread out too much so
one mailing list would be best (zdp@zope.org?). I also intend to make
regular announcements of ZDP's progress (and some advertising to get
people more involved in the project) on the main Zope list (or future
multiple main Zope lists :).

Right now though to keep the ball rolling I'll be using the normal list
to send out messages.

Zope.org would I think be the ZDP's favorite place to be hosted on, so
that'd be very nice. Your thoughts on how we could best arrange this
(who gets manage access to the place, if we develop in a branch we
export to you, or develop in there directly, or use FTP, or possibly
something else, etc) are welcome.

Independently (for local purposes) I've been thinking about making a FAQ
wizard product myself, but I got stranded somewhere in the beginning (my
laments I posted some time ago to the list :). But at least I've given
some thought to the design. Now Amos made one, and we can build on that.

The use of the tree tag is nice, but probably a simple list is more
useful in some cases (one can do a text search in it, for instance).
From my cursory glance at the management screens of the example, it
seems that it's not hard to produce that.

What would also be nice is some way to simply generate plain ascii text
versions of the FAQ as well, along with possibly some other versions. We
could also think about generating DocBook SGML (which then can be
converted in a lot of different formats with for instance the Linux
SGMLtools 2.0).

I haven't given too much thought to collaboration mechanisms. It would
be useful to have the ability to easily move questions around in the
list from one section to the other. My plan is to early on just get any
question/answer pairs we can come up with (from mining the mailing list,
documentation, and whatever people contribute). Later on we can then
organize these in categories, once the pattern becomes clear (likely
we'd have a DMTL section, for instance, and an installation section). If
there's flexibility in moving questions around the FAQ might be
developed more quickly. 

People could contribute question/answer pairs (or just questions) in
some 'contribution area' and the managers of the list can then edit
these and move them to the right sections of the list after doing so.
The contribution area should still be visible for everybody, so that
even the raw entries can be useful. I'm brainstorming right now, so
here's another idea: if someone sees a question in the 'contributed'
area that he knows the answer to, that person should be able to write in
an answer. Even with the already edited questions in the main list it
would be useful if people could leave comments ("I tried this but it
didn't work for such and such reason. But if I did this and that, I got
it working."). The editors can then later review all that's added and
integrate it into the main text.

Right now I intend to just assemble a big raw plaintext file (structured
text!), though; anyone can work with these. It's good to keep the
process moving.

Martijn

As long as the *me too!* message doesn't include the entire previous

I have no DNS, it's a local system only. I'm using Windows 95 and this
doesn't work. But it should no problem to "fix" the ftp_server. The
IP_ADDRESS could set in start.py and this address is used by the

Using the "in" tag's grouping capability, is there any way to get the count of

and a cell rowspanned for all the group's items (eg: related products and their

Message-ID: <01E40461E003D21195CC0080296495D80B12B3@gates.cdc-group.com>

While debugging a Product that inherits from OFS.Folder stumbled across
the following problem (copied from the debugger command line stopped
inside one of my Product's methods):

>>> self.__class__.__bases__[0].__bases__[3].__bases__[1]
<class OFS.CopySupport.CopySource at 8d11e0>

>>> isinstance (self, OFS.CopySupport.CopySource)
0

>>> (self.__class__.__bases__[0].__bases__[3].__bases__[1] 
     is OFS.CopySupport.CopySource)
1

The first line says self is an instance of OFS.CopySupport.CopySource,
the second says it's not. The class objects are identical.

My problem is that I'm not able to override one of 
OFS.CopySupport.CopySource's methods and to call the
base classes method from inside. At that point I get
a 
    TypeError: unbound method must be called with 
               class instance 1st argument

which usually occurs when calling an unbound method with
an instance of the wrong class.

I'm clueless..

No, there isn't. You will have to use the SQL statement, to add a calculated
value column to it's output. You should be able to use COUNT to achieve this.

Actually this example shows the beauty of Zope/Bobo programming -- the
code looks completely like normal Python code, no CGI hackery involved.

Anyway, this is really a Python question, IMO.  You don't the arguments
to the Child's constructor to be hardwired in the Parent, right?

You could take a route where pass a dictionary, e.g. REQUEST, into the
Child's constructor and let it figure out for itself what it needs.
This feels less OO and doesn't let Zope/Bobo help you with type
conversions and raising exceptions for missing arguments.

Good timing.  We are planning a Collector Day At The Beach pizza party
on Friday.  We'll gather everybody together for a couple of hours,
discuss a bunch of submitted issues, and try to clear them out.  I'll
articulate a policy on support within a week.

We still haven't emerged from our network hell -- our dedicated line
hasn't been installed yet -- but things are slowing getting under
control.

Count me in as well.  I'm meeting with some folks today to get a Zope
training course scheduled.  I'll create the preliminary docs which they
will improve and use for the course.  Thus I'll have some some material
for a (perhaps four day) training course to contribute.

BTW, is there any interest here in a Zope training course?

Subject: [Zope] [ZDP] Assorted FAQs
Message-ID: <36DD3FD7.F71EAE80@pop.vet.uu.nl>

Hi everybody,

Here is a start. I just randomly browsed the mailing list and created a
completely uncategorized set of questions and answers for the FAQ. I
even snuck in a question of myself, see if you can answer it. :)

If you see a problem with some of these questions or answers, send a
followup with suggested corrections to the list and I'll include them in
the FAQ. If you have more question/answer pairs, go ahead and followup
too. I prefer these things to appear in the list (in a thread, and
marked by [ZDP]) for now, as this might stop people from writing the
same FAQs twice. I hope in a while we'll get somekind of collaborative
FAQ environment going that makes all this easier.

I'd prefer additions to the FAQ in StructuredText for now. See what
follows for an example of the format I have in mind. If you think
another format works better feel free to convert. (yes, that's the theme
of open source; if you want something done differently, feel free to do
the work to change it :).

Here's what I have so far, enjoy!

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use:

        &lt!--#var "external_method_name(arguments)"--&gt
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is:

        &lt!--#var expr="external_method_name(arguments)"--&gt

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

Well, the underlying issue is the stateless-ness of the whole thing. In
normal python, you'd create an empty child, call the child's editing form
so the user can enter initial data, and only after the user's commit add
the child to the container:

def addChild(self):
     newChild = Child()
     if newChild.editForm() == true:
        container.append(newChild)

in short. I've attempted this in the ZPublisher environment, but to no
avail - either it didn't work at all or it got very messy (with the Child
needing to know about the Parent, etcetera).

I must say, I was under a bit of time pressure last night when looking for
alternatives (wanted to have a beta release on my website before
breakfast), I haven't got around playing with hidden form variables
etcetera yet - that could work. Just hoped somebody on the list here would
have a canned answer - I'm a lazy guy ;-)

Subject: [Zope] Some tough questions about zope... (long)
Message-ID: <v0410440eb302e9edd947@[128.240.198.13]>

Hi all,
This is quite a long email where I ask a lot of questions about Zope, 
but I hope you'll be lenient with me as I think I have a few hard 
decisions to make!

Some background:
I'm one of the web developers here, with a remit to implement a 
curriculum database that can;
(a) support the Medical Faculty here
(b) get rolled out to three other Medical-related sites, each with 
their own 'look and feel'
(c) possibly implement a University-wide curriculum database.

The curriculum database is essentially delivering online study guides 
(over 100 for each Faculty) whose source is originally from very well 
marked up Word Documents. In addition, we include multiple choice 
questions, file upload of lecture notes etc. and some 'active' web 
pages showing dynamical processes in medicine etc. The curriculum 
database needs to be searchable across its entire breadth (although 
initially restricted to the one site), so that students and faculty 
can find occurences of, say, 'lung cancer' in lecture resources - 
this is to plan for curriculum management, so that we can find out if 
we're pushing subjects too much (or indeed, whether we're pushing a 
subject at all!). We have other applications (nearly all of which are 
written in Perl/PHP3) and want to seemlessly integrate them into the 
curriculum database.

Currently we do all our development work on Unix, using Apache 
virtual web servers, MySQL as our database engine and Perl running as 
a CGI for most of our applications. My input has been to introduce 
PHP-3 (an Apache module with a bulit-in XML parser) and some XML 
knowledge to the group. I've been looking at a scenario where our 
study guides are converted in XML using Omnimark and held as static 
XML documents in a database. They are then rendered into HTML/RTF and 
put into static web directories. The student can run a program that 
extracts elements from selected XML documents and creates a 
customised set of HTML pages or RTF document that is built for them 
'on the fly'. My manager was a bit worried about all these static 
pages lying about and to be honest so am I, but extracting the 
relevant XML from a database to render into individual HTML pages 
seems a massive drain on the system.

I found out about Zope Monday morning, dl'ed it, installed it, got 
one or two things working... and have been worried sick ever since.

My problem? is that I can see how Zope can do so much for us, but it 
seems to need a hell of a gut-wrench to do so.
There also doesn't seem to be an easy 'half-way' house to move to Zope.
I've read a lot of the documentation, and am doing so constantly, but 
the wisdom of the list would be very helpful indeed.

The questions:
a) Is there a way for us to 'dump' the non-dynamic parts of a Zope 
database into static HTML pages. This would act as a way to say to 
the team "look, we have a parachute!".
b) Can I integrate with the Perl/PHP3 programs that we have (the Perl 
programs are mainly .cgi, but the PHP3 programs are server-side 
scripted, and as such are embedded into the HTML itself). This is so 
that I can
c) Is there any way of using the XML documents that I'm creating into 
the database and parsing them to produce either HTML or RTF output?
d) I know that this a terrible question to ask... but is Zope likely 
to 'remain' open-source (we're worried about getting stuck with a 
proprietary system)?.
e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
dropping the :port requirment).
f) I'd like to have the option to have user authentication 
information coming from a database - is this possible?
g) We have something like 200 main level directories holding the 
study guides, each with up to 200 files in them - is that pushing the 
Zope database too far?
h) We also need resources such as QuickTime movies, images PowerPoint 
slides etc. to be uploaded - would they sit in the database or can 
they be held somewhere else (and what happens about file name 
conflicts)?
i) Does Zope have the equivalent of 'server logs', which we use for research.
j) Is it possible to have a 'pointer' at a location in the Zope 
database that will point to a 'real, honest to goodness' HTML file on 
the server (ie something like a redirect..oops I think I may have 
answered my own question)
and lastly
k) What kind of loads have people put Zope under (10,000 +hits a day, 
100k?). We have one application which has 170 Medical Students 
sitting in front of screens and clicking a button at the same time 
(they're selecting their final year options) which then starts 170 
CGI-based Perl processes off interrogating and updating the database. 
This really grinds the system down...

I hope that I haven't bored everyone to tears here - it's just that 
Zope seems to do an awful lot of what I need, and I'd really like to 
know what I'm letting myself in for if I start using it for 
everything I do....

many many thanks,
tone.

Cookies or passing around secret messages would be the way to avoid
this, don't use Basic authentication at all.  The UserDB product shows
off a User Folder than uses cookies, and possibly today I am releasing a
User Folder product that authenticates off of a flat file, like
/etc/passwd for alpha testing which also uses either Basic or Cookie
auth.  If you use Cookie auth you are presented with a login/logout
screen to set/clear the cookie.

Message-ID: <199903031517.HAA31270@hipmail1.gohip.com>

Thanks for the help, but...

My problem is a little bit harder than that. The data in field2 is date *and* 
time. So like this:

field1 field2
------ ---------------
red    3/1/99 10:00 AM
blue   3/1/99 11:00 AM
green  3/1/99 03:00 PM
brown  3/2/99 10:00 AM
yellow 3/2/99 04:30 PM

I've seen in the guide where you can format a data field when outputting, but 
how do actually extract the day-of-the-month number and put it in a temp 
variable. The pseudo-code I've used before to do this before is:

tempday = 0
for each record
  if tempday<>dayofmonth(datefield) then
     print out a header
  print out other fields
  tempday = dayofmonth(datefield)
next

I'm just having a little trouble translating that into DTML. Creating a simple 
temporary variable seems overly complicated.

If you continue to use it you will get the Zope Zen. :)

This begs the question we've asked around here so many times, 'What is
data?'  Everything in Zope is Dynamic, in my thoughs, 'non-dynamic' is a
Document with not DTML in it.  But there is no way for Zope to sniff a
document and see if it contains dynamic structures or not.  Perhaps what
could be done is to write a simple MyDocument that you stipulate in
policy never to have dynamic stuff in it, and then write a crawler
scripts that sucks out all such documents into a local file structure.
There maybe easier solutions.

...do what? ;)  Zope can call your cgi scripts just like they are, as
URLs.  They would, of course, have to be external to Zope and if you
have a bunch of little ones you may find it better (and a damn sight
easier) to rewrite them as Python in Zope as external methods. (DTML is
also a rather powerful language for being so simple).  Just leave your
PHP stuff in your documents; Zope will parse out the DTML and return it
to the server, which will parse out the PHP stuff and return it to the
browser.  In fact, you can probably make DTML and PHP work together
nicely and simplify much of your PHP code.  In the quickie case you
don't need to change your PHP.

> c) Is there any way of using the XML documents that I'm creating into

Zope doesn't contain an XML parser.  You would need to do this with an
external package.

Yes.

Yes.

Yes.  There is an unsupported open source User Folder Product called
UserDB, where you tell it how to query your DB and it uses that for
authentication.

Not at all.

ooo.  Someone has yet to write an ExternalFile product (though I suspect
it would be fairly simple) to add objects to the db that refer to files
outside the db.  For now you can upload them as File objects to be
contained entirely in the db.  The same rules that apply to file name
conflicts in, say, a UNIX filesystem, apply to the Zope db.  You can't
have the same object id in the same folder. (With a minor non-exception
of aquisition, all lower folders can see the contents of higher folders,
but if you place an object in a lower folder with the same id as an
object in a higher folder the lower object will override the higher
object.  Get that?)

Since Zope is served through a web server you can continue to use the
server logs.  In other words, No. ;)  Object by Object logging is
something we've discussed, but would require *a lot* of thought and
work.

If that file is being served up by Apache then you can just use it's URL
as a 'pointer'.

Ah yes, the inevitable benchmarking question.  There are lots of issues
here, memory footprint vs processor speed vs concurrent access...etc.
The quick word is, Zope is fast and it will get much faster.  Zope is
currently not concurrent but will be in 2.0.  Zope+Apache is a bit slow
due to the pcgi bottleneck and is much improved by using ZServer.  As it
stands now, ZServer is something like twice to 10 times faster than
Zope+Apache.  Medusa (the web core of ZServer) serializes the requests
into Zope at the moment, but when 2.0 comes out it will be the fastest
web application platform on earth.  Don't quote me.

I will be looking into this, as soon as I have the time. The answer for now is:
probably, because everyone wants to download a local copy of part of any
website at some point. There are tools out there to do this, I haven't looked
for them yet.

Just run Zope via Apache (see below).

Python is very capable of parsing XML. You will have to write an External
Method to handle this, though. An example of XML parsing can be found at
http://www.zope.org/Download/Contrib/XMLConfig.tar.gz. This Zope Product parses
a static XML file for use in Zope.

I certainly do hope so. I intent to use it en expand on it heavily anyway, and
sodo others. These extensions will generally be Open Source themselves, making
it hard for Digital Creations to pull Zope out of the Open Source domain.

>e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
>dropping the :port requirment).

Yes. The doc/WEBSERVER.txt will start you on this. Be warned though, there are
some problems with Apache and Zope integration, for reasons that others are
better equiped to explain.

>f) I'd like to have the option to have user authentication

Yes, you can find the UserDB Product at
http://www.zope.org/Download/Prereleases/UserDB/UserDb-1.2.0-nonbin.tar.gz.

Nah, Zope has handled much more than that allready. Ask Paul =).

Zope can store any filetype you want it to. Filename conflicts are handled the
same way a filesystem handles them: In the same Folder, you cannot have two
objects with the same name at once. But because it is a hierachical system, you
can use the same name in two different folders.

>i) Does Zope have the equivalent of 'server logs', which we use for research.

ZopeHTTPServer's output is it's serverlog. You can start it up with STDOUT
redirected into a file. When you use Apache as your webserver, all requests
will be logged through Apache itself.

Zope will be much much faster. I can't give you any direct numbers, maybe
someone else on this list can. You basicly don't have the overhead of starting
a fullblown new process for every request, and Zope pools Database connectiosn
for you, so you don't have the initial connection overhead either. And, your
code isn't compiled everytime, like with Perl.

I know the feeling. I was choosing between ColdFusion and Zope for
developing my new application and had some similar questions. Ultimately,
I chose Zope.

[nice application description deleted]

| a) Is there a way for us to 'dump' the non-dynamic parts of a Zope

| the team "look, we have a parachute!".

Right now, there isn't. This question has come up repeatedly on the list,
to the point where DC is getting sick of hearing it and thinking of actually
implementing something :)

They have said it would be pretty easy, and I believe it. I think 
the basic idea is to write a method that will go through the Folders and
use the DocumentTemplate code to render out the pages.

| b) Can I integrate with the Perl/PHP3 programs that we have (the Perl 
| programs are mainly .cgi, but the PHP3 programs are server-side 
| scripted, and as such are embedded into the HTML itself). This is so 
| that I can

If you're using Zope with Apache, you use mod_rewrite to get the
authentication headers passed to Zope. You can also use mod_rewrite to
decide how URLs map to content on your server. For example, you can
have all of the content on your site go through your Zope.cgi, but
/cgi-bin/* can go directly to your CGI or PHP files. You can access
MySQL from Zope, PHP and Perl, so they can all use the same data
source for the databases.

| c) Is there any way of using the XML documents that I'm creating into 
| the database and parsing them to produce either HTML or RTF output?

I'll leave this one to people more knowledgeable about XML.

| d) I know that this a terrible question to ask... but is Zope likely 
| to 'remain' open-source (we're worried about getting stuck with a 
| proprietary system)?.

I think it would be tough for DC to try to take it back at this point :)
Even if DC did decide to not release any more updates to Zope, the community
would probably continue working from the 1.10.2 code. Anyhow, DC had
sound business reasons to release Zope as Open Source. Over time, they
will likely get a lot of benefits by having done so and by encouraging
outsiders (like us) to work with and improve Zope.

| e) Can I 'point' an Apache virtual server to run a Zope cgi (ie 
| dropping the :port requirment).

Yes. This uses a technique called Persistent CGI. It works quite well.
There is also a hope that there will be better integration with Apache
in the future. Also, as ZServer stabilizes, you may find good reason to
migrate from Apache to it.

| f) I'd like to have the option to have user authentication 
| information coming from a database - is this possible?

There is an unsupported bit of code called UserDB which is designed for
this.

| g) We have something like 200 main level directories holding the 
| study guides, each with up to 200 files in them - is that pushing the 
| Zope database too far?

Though I have no first hand experience with a Zope DB this large, the
DC guys have said that they've worked with some very large DBs.

| h) We also need resources such as QuickTime movies, images PowerPoint 
| slides etc. to be uploaded - would they sit in the database or can 
| they be held somewhere else (and what happens about file name 
| conflicts)?

You could put them in either place. There would probably be some
advantages to putting them in the database. For example, your standard
Zope security rules will apply to the downloading and updating of the
files.

| i) Does Zope have the equivalent of 'server logs', which we use for research.

I don't know about ZServer, but if you use Apache as your web server you
will be able to use your standard server logs.

| j) Is it possible to have a 'pointer' at a location in the Zope 
| database that will point to a 'real, honest to goodness' HTML file on 
| the server (ie something like a redirect..oops I think I may have 
| answered my own question)

Yes, you can do a redirect.

| and lastly
| k) What kind of loads have people put Zope under (10,000 +hits a day, 
| 100k?). We have one application which has 170 Medical Students 
| sitting in front of screens and clicking a button at the same time 
| (they're selecting their final year options) which then starts 170 
| CGI-based Perl processes off interrogating and updating the database. 
| This really grinds the system down...

I've heard it said that Zope should be able to handle 500k hits or more
on reasonable hardware. Of course, this depends on exactly what the
server has to go through for each of those hits, etc. DC is also working
on concurrency for Zope 2.0. This will probably enable you to handle a
whole bunch of requests.

Good luck!

You'll have to use SQL function for this. In MySQL you could do the following:
SELECT field1, DATE_FORMAT(field2, "W, M d") as datefield FROM MyDB.

Put this in a Z SQL Method, and then the following DTML will get you your
results:
<!--#in MySQLMethod sort=datefield-->
  <!--#if first-datefield-->
    <!--#var datefield-->, 
    <BLOCKQUOTE>
  <!--#/if-->

  <!--#var field1-->

  <!--#if last-datefield-->
    </BLOCKQUOTE>
  <!--#/if-->

<!--#else-->

Everybody on this list is lazy ;-)

This is my approach:
First define a Webobject class that every object needs to inherit. The
simplest could be just:

class WebObject:
	        
    def __init__(self,name):
        '''__init__(self,name)
        '''
        
        self.name=string.replace(name,' ','_')

    def _set_root(self,root_obj,parent_path):
        '''_set_root(self,root_obj,parent_path)

        sets the root object and relative path. Note: 
	one will never need to pass parent_path directly. I also need
	to have a reference to the root object so I can do stuff remotely
	similar to acquisition'''

        self.root=root_obj
        self.rel_path=parent_path+self.name+os.sep

class Container(WebObject):

    def __init__(self,name):
        WebObject.__init__(self,name)
        ##Holds contents
        self._d={}

    def __getitem__(self, key): return self._d[key]

    def items(self): return self._d.items()

    def _do_add(self,object):
        '''_do_add(self,object)

        Adds object in container. Object MUST have inherited the
        WebObject class.'''

        name=object.name
        if hasattr(self,name) or self._d.has_key(name):
            raise ValueError,'Object with same name exists in WebFolder'
        d=self._d
        object._set_root(self.root,self.rel_path)

        d[name]=object
        self._d=d

So you can create any object that has inherited the WebObject class
independently and add it to the container instance.

Subject: [Zope] [ZDP] Tree FAQs
In-Reply-To: <36DD3FD7.F71EAE80@pop.vet.uu.nl>
Message-ID: <4.1.19990303153836.00a64c50@lisp.atmm.nl>

My two cents on the tree tag:

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute of
    the tree tag. The objectValues function of a folder returns all objects
    contained by that folder. 

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML 
    Document objects in a Folder. Other metatypes you could select on are:
    Folder, DTML Method, File, Image, Mail Host, User Folder and Session.
    This is not a complete list, as Products can and will define their own
    metatypes. If you want to show more types, just add them to the list,
    like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        &lt;!--#tree branches_expr="objectValues(['Folder'])"--&gt;
	    &lt;A HREF="&lt;!--#var URL1--&gt;/&lt;!--#var id--&gt;"&gt;
            &lt;!--#var title_or_id--&gt;
            &lt;/A&gt;
	&lt;!--#/tree--&gt;

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a tree, is
    called with ?expand_all=1, the tree tag will expand all it's branches.
    Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand 'buttons'::

        &lt;A HREF="&lt;!--#var URL0--&gt;?expand_all=1"&gt;
          Expand all&lt;/A&gt;|
        &lt;A HREF="&lt;!--#var URL0--&gt;?collapse_all=1"&gt;
          Collapse all&lt;/A&gt;

        &lt;!--#tree--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        &lt;!--#tree single--&gt;&lt;!--#var id--&gt;&lt;!--#/tree--&gt;


More cents will follow.

This sounds like something we need.
I know that I could use it.
If folks will critique this design, I'll implement it.

- - Proposed Access Method - -
It is desired to be able to have "non DTML" files incorporated
in a Zope URL system. These files might be static GIF files,
quicktime movies, or just plain old HTML.

Obviously, they might be "included" in a DTML page by simply
referencing them directly by their URL. However, I can see cases
where one would like the access to be under the control of the Zope
system.

For example, access controls might apply.

I believe that we can achieve this by having an object
which represents an ExternalFS mount point.

In general, we map a URL onto a node of the FS.
It would be directly analogous to a symbolic link (ln -s).

The Zope mount point would enforce permissions just as if the
file were loaded into the Zope DB.

Objects can be "imported" without having them take up space
in the database. Their creation and maintanence can be handled
outside the Zope system.

They are rendered by "cat"ing their contents.

By permitting substitutions in the link, we can create effective
reformatting of the visible FS.

As an example, I am monitoring customer traffic. "mrtg" automatically
generates graphs for each customer.

In Zope, I could create customized displays by importing these files.

By using the ExFS, I can update the graphics without affecting Zope.

Further, assuming
 /mygraphs/today/customer1.gif
 /mygraphs/today/customer2.gif
 /mygraphs/yesterday/customer1.gif
 /mygraphs/yesterday/customer2.gif 

we can map them onto

somewhere/KustomerA/graphs/today
somewhere/KustomerA/graphs/yesterday


by substituting a property of the Kustomer

- - - 

Thoughts and/or suggestions?

Time to move this to zope-dev?

anyway, I think this sounds like a good idea. It harkens back to an 
inquiry I made about byte-serving PDF files. I don't want to dump my 
pdf's into the database.

If you can implement this, I think I could implement byte-serving.

Although byte-serve could be handled at the ZServer level, I think for 
large external files it'd be more effective at the "cat" level

This is a good idea. I can see this FAQ growing very, very quickly.
So, I would suggest that we start thinking about a hierarchy

Installation

How safe would it be, to allow any random user to use the add menu to create
arbitrary symlinks into the native file system tree?

Rather than using rowspan, use nested tables. I haven't done this in
Zope yet, but it was always my solution of choice in ColdFusion. It also
makes it easier to debug your layout in a WYSIWYG editor. It does, of
course, bloat your HTML a bit.

It will work, and I'm going to have to in the short term, but I really would
like the multiple columns for each item to line up down the page, without ugly
fixed-width hacks.

Maybe by splitting up the FAQs we could split up the work, too! Have a
different person/group resposible for each FAQ.

Of course there would be nothing stopping some energetic type being
involved with all of them :)

Also, I think that HOWTOs of the Linux type would be a great idea. They
have a person/group responsible for each HOWTO to keep it up to date and
add/edit things as needed.

I am just commenting from the sidelines. Right now I barely have time to
scan through the zope-list!

Well, I think it'd be nice if there was someone "responsible" for each

You can find a "howto" LaTeX stylesheet in the Python CVS checkout, and
I'm sure Guido/Fred wouldn't mind us using this.  It works real well,
and can target HTML, ASCII (I think), Postscript, PDF, etc... this lets
you do the "bigger" stuff in a nice pretty way. 

What would also be nice is a list of "bigger" issues that people would
liek to see explained more... something that's more than a single
question.

Ok, I found:

the link on that page:
you can grab [Fred Drake's documentation 
distribution], and use...
Is broken with a "Error 404: File Not Found"

Message-ID: <613145F79272D211914B0020AFF6401907BACC@GANDALF>

Greetings,

(This is crossposted because it is a product anouncement, and contains
interesting developer pointers)

I've have massaged the source code for UserDb and created a new user
folder products called etcUserFolder.  This products authenticates off
of a flat file of usernames:cryptedpasswords.  If there is anything
trailing the crypted password it is ignored, so any /etc/passwd file
will work.  It is generaly not recommended, however, to use your
/etc/passwd file for security reasons.

This is an unsuported product and has been written because it was asked
for a few times, and I felt the community could use another good example
of writing user folders.  It also shows off cookie authentication which
Brian perfected with UserDb.  Here is the documentation:

etcUserFolder requires a directory called 'etcUsers' in which to place
your file containing the uid:pwd pairs.  This directory may be an
INSTANCE_HOME (typicaly your top level Zope dir), SOFTWARE_HOME
(typicaly 'lib/python') or in the etcUserFolder directory.  Jim wrote a
nifty function called getPath that sniffs all of these places for a
directory and file of your choosing.  This function is included in
etcUserFolder and will be included as a standard function of the next
release.  Other Product authors may find it interesting.

Since the flat file is meant to be b/w compatable with /etc/passwd and
htpasswd style files, there is no Role associated with the users it
authenticates.  You can specify a default role which is, by default,
'etcUser'.

I have not done extensive testing of this, therefore it is a
pre-release.  Please send bug-reports and hopefully a patch to me

Message-ID: <v04003a03b3034df988d1@[192.168.1.190]>

I just upgraded to 1.10.2 and I noticed that when creating a new document I
have a choice of DTML document and DTML method. This seems useful. I
noticed that all my DTML documents and DTML methods have the icon for a
DTML method. Everything seems to work.

What is the difference between a DTML document and a DTML method? Seems to
me a method should not be surfable but they are.

Is it possible to change my documents to DTML documents? Even just for
housekeeping.

One other unrelated question: What is a Principia Draft?

I just had a quick exchange with Fred Drake (who handles most of the
documentation duties for the Python organization), and he is aware of
this problem, and has forwarded the issue to AMK who is responsible for
teh HOWTO stuff.  IN the mean time, he suggests grabbing the latex
documentation whihc will have it all in it.  If this is too painful, I
can post a snapshot of the pieces taht are needed from the current CVS
repository.

The URL for the LaTeX documentation is:

I would love to see this feature (generating DocBook SGML). I thought
about something like this myself (for my howto), but I just don't have the
time at the moment. I could probably find enough time to help out a little

Message-ID: <36DDA463.683D9460@avalongroup.net>

Hi,

I'm playing with Zope, and have been trying to get Zope to talk to MySQL
using the MySQLDA.

I'm running RedHat 5.2

Since there were caveats about having MySQL development enabled, and
such, I downloaded the source distribution for MySQL and made it. It
appears to be working very nicely.

When I follow the procedures outlined in the README, the following
happens:

I run make -f Makefile.pre.in boot and everything works correctly.

I then run make and get the following error.
gcc -fPIC -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5
-DHAVE_CONFIG
_H  -I/usr/local/mysql/include -I/usr/include/mysql -c ./MySQLmodule.c
./MySQLmodule.c: In function `pythonify_row':
./MySQLmodule.c:238: warning: assignment from incompatible pointer type
gcc -shared  MySQLmodule.o  -L/usr/local/mysql/lib -L/usr/lib/mysql
-lmysqlclien
t -lm -o MySQLmodule.so
ld: cannot open -lmysqlclient: No such file or directory
make: *** [MySQLmodule.so] Error 1

I did a locate on mysqlclient, and coudln't find the file. though I did
find some called libmysqlclient. So I changed the both Setup and
Setup.in to reflect that other name. however, I still get the above
error.

Any help would be greatly appreciated.

Your problem wasn't with the library, -lmysqlclient refers to
libmysqlclient (think of the -l as short for lib). The problem probably
was that libmysqlclient wasn't on the path gcc searched for libraries.
This is controled by the -L argument (-L is library paths). 

So... here's what to do:

1. Get everything cleaned up (ie. back in the condition after first
   untarring ZMySQL).
2. Edit Setup.in, add -L<the path to libmysqlclient> to the end of the
   last line.
3. Proceed as usual (make -f Makefile.pre.in boot; make)

If this would work (having Apache parse the PHP code in the pages returned by Zope), you would save me a lot of painfull converting working PHP code (mainly database related) and I would gradually convert from PHP/Apache to Zope/Python/Apache.

Pleaz tell me how this neat trick is done... (maybe some fiddling with the headers???)

Hint:
Creating a DTML Document/method with the following contents doesn't fool Apache in rendering PHP!

<!--#var standard_html_header-->
<h2>Give me the (PHP) money...</h2>
Read the phpinfo between the lines... NOT!!

This is my take on the situation.  As far as I can tell this is pretty
deep voodoo.

A DTML Method is what used to be just a Document in pre 1.10 releases.
DTML Methods are not objects, they are methods.  If you have a folder
called foo, and it contained a DTML Method called bar, then bar is a
method of foo.  foo doesn't contain the object bar, it has the method
bar bound to it.  What this means is that from bar's point of view,
'self' is a Folder object, and any properties it sees are properties of
foo, not itself.

DTML Documents are Zope Objects.  Their idea of 'self' is themselves.
They are contained in folders, but are not methods bound to that folder,
they are instances of DTMLDocument.DTMLDocument.  They can manage their
own Properties (because they inherit PropertyManager.PropertyManager).

Both DTML Documents and DTML Methods can hold DTML and content.  The
difference is subtle.  DTML Methods would be used when the answer to the
question 'Am I showing some other objects content through me?' is Yes.
DTML Documents should be used when the answer to the question 'Am I the
content I want to display?' is Yes.  DTML Methods have the advantage
that they don't have any properties, and their perspective of aquisition
is from their containing folders point of view.  DTML Documents have
properties which may interfere with aquisition you'd want to do, and
aquisition is from their own point of view, which may not be what you
want.

(BTW Martijn, perhaps the above should go in the FAQs)

If this isn't clear to you don't worry, it isn't even really clear to
me.  There is no way, but there really should be a way to convert
between the two because the roles for a DTML widget may change from
Method to Document as your system evolves.  This will probably be a
feature in the next release.

(This is the answer to the question 'Can I convert between DTML Meths
and DTML Docs?' for the FAQs)

Message-ID: <36DDB670.4B15C6A4@networklogic.com>

Version 0.3 of ZPyGreSQLDA has been posted to the Contrib area of the
Zope site.

This version upgrades to PyGreSQL 2.3 and compiles under Zope-1.10.2. It
now closes the backend connection to postgres when the database
connection is shut down from Zope.

You almost made it ;=)
The -lmysqlclient does refer to the libmysqlclient you found, but you should only modify the path pointing to it. This is done in the Setp[.in] just before the -lmysqlclient; modify the '-L/<path-to-the-libmysqlclient>', if have this set to -L/usr/local/lib/mysql.

[ZDP] Maybe this is something for the FAQ?

This can't be done currently. I researched this a while back, trying to
get server side includes to work. There's actually an entry in the Apache
FAQ about it:

"""
9.How can I have my script output parsed? 

     So you want to include SSI directives in the output from your CGI
     script, but can't figure out how to do it? The short answer is "you
     can't." This is potentially a security liability and, more
     importantly, it can not be cleanly implemented under the current
     server API. The best workaround is for your script itself to do what
     the SSIs would be doing. After all, it's generating the rest of the
     content. 

     This is a feature The Apache Group hopes to add in the next major
     release after 1.3. 
"""

Though this is about SSI, it basically means (I believe) that apache can't
take back the output of a CGI for additional module handling.

Hi  Sture,
try to use the P MySQL Input wizard in the contrib download area. It
will automatically create a insert sql method and a form for you. So you
can just follow the pattern.

<a nice dissertation on variable indirection, which I now understand>

I'm piggy backing this on Amos's post from a while ago, because that is
where I finally found my answer. I could have sworn I had seen (and
used!) a DTML code fragment that displayed the form variables sent to
it, with there values. Obviously, this involves indirection. 

After hunting through my (extensive) zope-list archive, I couldn't find
it, so I started over, with the help of Amos's text and wrote one. I
often need little tools like this to debug between my forms and sql
actions, so I can see what's really going on!

I call it 'show_vars'

The only tricky thing in it is that sequence-item is an invalid variable
name, so I need to wrap it in _[''] which leads to the double wrap when
dereferencing to get the value. Anyway, hope someone else finds it
useful!

<!--#var standard_html_header-->

I haven't tried it, but it could possibly be done by running two
Apaches: one which stands "in front of" the other.  The front-side
Apache would rewrite every access into a PHP wrapper-script which
include()s a corresponding URL from the back-side Apache where the
Zope things would be done.


On the other hand, I really should be asleep now so all this _may_
be utter nonsense, but I do think it's possible.  It may even be
possible with a single Apache, but that's more hairy than I dare think
about right now.  Good night.

(Btw, my suggested hack isn't in total disagreement with the quoted 
FAQ entry, because my hack surely won't work with SSI.  PHP3 isn't an
official Apache module, so they don't neccessarily mention things like
this in their FAQ.)

I'm attempting to use ZServer's ftp daemon to upload a number of

I've tried this with an image that doesn't exist, as well as for one
that already exists. Is it just a matter of "it doesn't work for images"
or what? Also, where does ZServer send errors from ftp sessions? It looks
to me like it's just silently eating them. :(

In all the world you might find 4 machines still plugged in that
support 'record' or 'page' structure.  The default is 'file', which is
what that command is trying to do.

Add these two methods to ftp_server.py::ftp_channel

    def cmd_stru (self, line):
        'obsolete - set file transfer structure'
        if line[1] in 'fF':
            # f == 'file'
            self.respond ('200 STRU F Ok')
        else:
            self.respond ('504 Unimplemented STRU type')

    def cmd_mode (self, line):
        'obsolete - set file transfer mode'
        if line[1] in 'sS':
            # f == 'file'
            self.respond ('200 MODE S Ok')
        else:
            self.respond ('502 Unimplemented MODE type')


And that should do the trick.

Micheal answered these perfectly.

>One other unrelated question: What is a Principia Draft?

It is a special use of the session object, but it appears to be partially
broken. When you create a Principia Draft, it asks you to specify an
orginal object, from the same Folder you are creating the Draft in. This
will be your 'draft', on which you can make changes invisible to the
outside world.

The draft contains an invisible Session object that is immediatly started
and joined, and an invisible UserFolder to facilitate extra users (for
example, customers that want to be able to view your work on it as well,
but have no access to it otherwise).

The Principia Draft suffers two problems however. The first is really a
Session object bug, in that security for Session objects is broken. This
has allready been reported as a bug to the Collector by me. The second
problem is that the Userfolder and Session controls are inaccessible via
the management screens.

The latter problem is caused by convention changes in the Folder object (or
the ObjectManager class really, used by Folder. I think that Folder objects
_used_ to call title_and_id on a object when displaying it in it's
management screen, but the current release of Zope constructs the id and
title of an object by using it's id and title separetly. Principia Drafts
made use of the call to title_and_id to insert links to its UserFolder and
Session controls. As this now doesn't happen anymore, you will have to do
this yourself.

As long as you have access to Session objects, you can change users on a
Principia Draft object by calling it's users__draft__.manage_main method,
and reach the Session controls by calling its manage_approve__draft__
method. The URLS are:
http://yoursever.com/Zope/Draft/users__draft__/manage_main and
http://yoursever.com/Zope/Draft/manage_approve__draft__

   As far as I understand there are DTML objects (templates), Products and
External methods. There is no such thing as "Internal" methods (objects,
that live in Zope's object database). Are these 3 the only 3 kinds of
executable (callable) things?

* How can I show all form data/cookies/REQUEST vars without knowing their

    By using the #in tag, you can easily all show all data in any dictionary
    object, like REQUEST.form, REQUEST.cookies and even REQUEST itself. Just
    call the items() method of the dictionary, and the #in tag will provide
    a sequence-key and sequence-item variable for every item in the
    dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>
        <!--#/in-->

    Use REQUEST.cookies.items() for all your cookies, and REQUEST.items()
    for all REQUEST variables, including CGI Environment variables.

In-Reply-To: <4.1.19990304101312.00b9b100@lisp.atmm.nl>
Message-ID: <4.1.19990304103150.00b90ef0@lisp.atmm.nl>

Take two, now with escaped HTML....

* How can I show all form data/cookies/REQUEST vars without knowing their
names?

    By using the #in tag, you can easily all show all data in any dictionary
    object, like REQUEST.form, REQUEST.cookies and even REQUEST itself. Just
    call the items() method of the dictionary, and the #in tag will provide
    a sequence-key and sequence-item variable for every item in the
    dictionary.

    Show showing all form data can be done like this::

        &lt;!--#in "REQUEST.form.items()" sort--&gt;
        &lt;!--#var sequence-key--&gt;: &lt;!--#var
sequence-item--&gt;&lt;BR&gt;
        &lt;!--#/in--&gt;

    Use REQUEST.cookies.items() for all your cookies, and REQUEST.items()
    for all REQUEST variables, including CGI Environment variables.

I'm randomly assuming here you know more about DocBook SGML than I do,
so here I'm involuntarily inofficially  but you can back out of it
immediately appointing you the ZDP DocBook SGML expert. :)

I think perhaps the first thing you could do is get together with people
in the Latex thread for docs; they seem to have come up with it
independently. I know even less Latex than SGML and SGML seems a closer
fit with the XML-ish direction the web's taking, so my question would be
to point out the advantages of SGML to everybody.

[snip proposed hierarchies]

Yup, splitting up the FAQ into different categories appears to be pretty
needed, so this is a good idea. My idea is to 'involunteer' you category
maker guys to take the assembled FAQ that I'll produce hopefully today
(in a few hours), and put each question in the category you feel it
belongs to. This way I have to do less work and thinking. :)

Subject: [Zope] Bobo or ZPublisher and stdout ( Solution: Client/Server)
Message-ID: <36DE5733.60F87988@oi42.kwu.siemens.de>

Hi,

I already sent some postings to this topic, but I would like
to discuss the following problem again and how it could be solved.

Imagine there is a big C++/Python project.
The application is mainly prgrammed in C/C++ und one supports
a scritpting interface to that application via the SWIG mechanism -
the target language is Python.

During the developping process many stuff is written to the stdout -
during initialization ( before the main-function ), during execution (
in the main-function ),
and in the destructors of the static instances ( after the main-function
).

Now we want to do some web-stuff via ZPublisher, we define
a function which return a html string, which is calculated through
calling functions
from our scritpting interface of our application, that means beside my
correct
calculated string there is many stuff sent to stdout, that confuses
the Xserver and I get an error.

Ok, you would say switch the stdout to a file via calling c-funcions
like dup() or dup2( ) and
encapsulate this in a function (wrapped via SWIG), which is called in
the function which I call from
the URL in the browser.

Less cryptic:

 xy.py:

   start():
       "XXXXXXX"

        #Now all stdout goes in a file
       stdout2file( "log.txt")

        ....
       HTMLstring = ....

        # sitches the stdout back ( REVerse )
        # The way is free for CGI
        REVstdout2file()

        return HTMLstring


the URL:    http://myserver:3333/yyy/cgi-bin/xy/start

BUT with this method I have no chance to chatch stuff which is written
to the stdout
in the destrutors of the static instances, because we already have
switched back to the
"usual" stdout (for a correctly working cgi-mechnism).
The some problem one have with things which are written
to the stdout during the initialisation of the static instances.
( Imagine python itself is compiled
against a library which writes some stuff to stdout during
initialization).

I see only one solution:
If there is a ZPublisher Server process which says to a client process
do everything
and give me a calculated string via sockets or something like that, I
have not to take
care about stuff which is written to the stdout at the client process.

Or are there better solutions ?

   Thanks in advance,

    Armin

Yes, this would be a good idea. My first priority however is to get as
much of a FAQ as possible out there. Organization we'll do at the same
time. Otherwise we run the risk getting bogged down in organizing who
does what. 

That said, volunteers who want to manage specific sections of the FAQ
are very welcome to step forward. Procedure is as follows: you get to
name your topic; the first person who names a particular topic and
produces a FAQ for it (assembling it from the FAQ we have now, and
hopefully adding more of his or her own to it) will be manager for that
section, unless that person doesn't want to, of course. :)

I suggest to mail this list instead of me personally, so that other
people can respond friday and during the weekend, when I won't be around
to check the mail. We're working on getting a zdp@zope.org mailing list
too, but I can't say yet when that'll be ready.

Aren't there some HOWTOs out there already on the Zope site? (there are
FAQs too but that doesn't stop us of course). HOWTOs and FAQs of course
have some overlap; we'll just see how it evolves.

Earlier I suggested using SGML Docbook for this purpose; I've appointed
John Eikenberry (without any feedback from him :) as our official SGML
docbook expert. One advantage of Docbook SGML is that it's the new Linux
standard for writing documentation.

I think essentially a HOWTO is a particular frequently asked question
with a very long answer. :)

My rough sketch right now is a four-day course:

Day One -- Zope for Content Managers
Day Two -- Zope Programming Using Zope
Day Three -- Zope Programming Using Python
Day Four -- Relational Databases and Zope
         -- Zope for System Administrators

It would be a professionally produced and delivered "in the classroom"
class, a la Learning Tree.

That is, I won't be doing it. :^)  Instead, I'll produce a poor version
of the whole thing and give it to them, including the first customer
that will send maybe 7 people.  My poor version would probably become an
online version.

Just my thoughts currently.

I guess this counts as an announcement. Ken asked me to do it, but I
just mailed him I'd rather he did it (as he knows more about these
things than I do, and I won't be available to deal with problems until
monday, after today, thursday).

But, now you did, so that's fine too. :)

Hi everybody,

Here is the new ad-hoc FAQ. I'll start versioning it as of now; this
is version 0.1. How we'll do the actual versioning we'll still have to
decide on, but at least we have a way to refer to this one now.

Note on the use of the Zope mailing lists:

    The Zope Documentation Project is getting its own mailing list
    (zdp@zope.org). In an attempt to gain publicity and support among
    the Zope community, I'll post this development FAQ to the main
    Zope list as well, however. Feel free to respond to it on either
    list for now, but you are encouraged to join the ZDP mailing list
    and to send new FAQ suggestions there.

    You can subscribe to the ZDP mailing list by using the page:

        http://www.zope.org/mailman/listinfo/zdp

Note on the categorizing of this FAQ:

    This FAQ is a FAQ in progress. It is uncompletely unstructured,
    unrelated questions are mixed haphazardly. If you feel the calling
    to categorize the FAQ or to maintain the questions for a
    particular topic, feel free to mail your changes to the list, and
    thanks in advance!

Note on the code examples and StructuredText:

    I've reconsidered and used normal '<' and '>' characters in sample
    DTML, for the reason that at least the FAQ is readable as text
    then. If you try to feed this FAQ through::
     
        <!--#var faq.stx fmt="structured-text"-->

    there will be an error message in Zope, however. For some reason
    Zope seems to try to interprete even StructuredText that uses &amp
    escape codes. Until this issue is resolved it is not possible to
    render this document into HTML.

    In my uninformed opinion, StructuredText code examples shouldn't
    be interpreted by Zope as actual DTML. There may be some rather
    subtle technical difficulties involved however. Any input on this
    is very welcome. Until the matter is resolved, the FAQ document
    will use StructuredText in the plaintext readable way.

    Thanks to Martijn Pieters in being so considerate to supply HTML
    escaped DTML examples; it's unfortunate his efforts weren't useful
    this time.

Note on my availability:
    
    Martijn Faassen (me!), ad-hoc FAQ maintainer of the ZDP's Zope FAQ
    is generally not available to read or respond to email on friday,
    saturday and sunday. It is suggested ZDP related communication
    goes through the ZDP mailing list at zdp@zope.org anyway, and is
    not sent directly Martijn. This way anyone who wants to do
    something for the ZDP (such as editing and extending the FAQ) does
    not have to wait for Martijn to read his mail, having all relevant
    information available on the list.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.
 
* Why does StructuredText have trouble rendering the '#var' tags in
  the FAQ? Why do you use the HTML &amp escape codes in the FAQ when
  they don't work well either?

    I suspect there is some interaction between StructuredText and
    DTML that causes '#var' tags to be interpreted even when in a
    StructuredText code block (indicated by '::' or single quotes). I
    don't know any workaround right now, so I leave in ugly escape
    codes to encourage suggestions. :)

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like REQUEST.form, REQUEST.cookies and even
    REQUEST itself. Just call the items() method of the dictionary,
    and the #in tag will provide a sequence-key and sequence-item
    variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
        <!--#var sequence-key-->: <!--#var sequence-item--><BR>
        <!--#/in-->

    Use REQUEST.cookies.items() for all your cookies, and
    REQUEST.items() for all REQUEST variables, including CGI
    Environment variables.

* What is a Principia Draft?

    It is a special use of the session object, but it appears to be
    partially broken. When you create a Principia Draft, it asks you
    to specify an orginal object, from the same Folder you are
    creating the Draft in. This will be your 'draft', on which you can
    make changes invisible to the outside world.

    The draft contains an invisible Session object that is immediatly
    started and joined, and an invisible UserFolder to facilitate
    extra users (for example, customers that want to be able to view
    your work on it as well, but have no access to it otherwise).

    The Principia Draft suffers two problems however. The first is
    really a Session object bug, in that security for Session objects
    is broken. The second problem is that the Userfolder and Session
    controls are inaccessible via the management screens.

    The latter problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately. Principia Drafts made use of
    the call to 'title_and_id' to insert links to its UserFolder and
    Session controls. As this now doesn't happen anymore, you will
    have to do this yourself.

    As long as you have access to Session objects, you can change
    users on a Principia Draft object by calling it's
    'users__draft__.manage_main' method, and reach the Session controls
    by calling its 'manage_approve__draft__' method. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main 

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

Hm, DTML methods can be called as well, naturally, that's why they're
called methods. They're called through URL. The DTML method then is
executed. This means executing any DTML in it and returning the
resulting HTML to the caller. One way of 'calling' a DTML method is by
using it in a form action, like this:

    <form action="your_dtml_method" method="POST"> 

(or method="GET", of course)

This does go through the browser, but it feels like you're calling
'your_dtml_method' when the user presses the submit button.

This is another way of 'calling' a DTML method:

<!--#var your_dtml_method-->

I'm sure there are more ways, and I'm a bit vague about this, so I'll
leave it up to other people to turn this into a nice FAQ. :)

Martijn

So that is what the MySQL Input wizard does. I've been meaning to look at
it. Instead of saving time by using it, I did it manually. It is not that
hard but you have to understand what is happening.

1. HTML form (eg. form_html) collects data and sends it to a DTML document
(eg input_html) (that is the only tricky concept).

For example:

<form action="input_html" method="get">
  <input name="num:int">
</form>

(That :int tag does error checking. It is optional. They are documented in
the Z SQL Database Methods User's Guide)

2. The receiving doc (input_html) calls an SQL method (eg input_sql) with
an in tag.

<!--#in input_sql-->
<!--/in-->

If you do a select after your INSERT or UPDATE you can use it between the
in tags, otherwise you can just display a message or do a redirect after it.

3. Your SQL method (input_sql) would be something like:

INSERT INTO database (num)
VALUES (
   <!--#sqlvar num type=int-->
)

<!--#var sql_delimiter-->

SELECT num, etc

You don't need to do a select but if you do don't forget the <!--#var
sql_delimiter--> between any SQL statements.

Have fun!

If you don't do anything with the returned data, a #call will suffice:

<!--#call input_sql-->

Hi.  I've been getting a lot of confusing complaints about gadfly

ZGadflyDA doesn't support more than one db, gadfly does.
ZGadflyDA doesn't support newlines in string literals, gadfly does.
ZGadflyDA doesn't include kjbucketsmodule which makes gadfly run 10x
faster.
ZGadflyDA packages gadfly beta 0.2, whereas the current release is 1.0

As a new zope user, and also according to my general documentation
sensibilities, 
i suspect it would be very valuable to have a catalogue of the various
special variables (like sequence-key and sequence-item) and the various
entities (REQUEST.cookies, ...) available to the DTML programmer.  There
may already be some sort of catalogues around - in which case pointers
to those kinds of resources would be very nice to have...

I think at least this part of your problem may be due to the fact that Zope
is running as a different user under IIS than it is under ZopeHTTPServer.
My guess is that it can't see your datasources since they weren't created
as 'System' datasources. Check under the windows ODBC control panel and
make sure your DSNs appear under 'system dsn', not 'user dsn'.

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the

The file does exist, so I am once again stumped.

post script:

The current usage of gadfly in Zope makes gadfly do lots of parsing as in

insert into table(a,b,c) values (1,2,3)
insert into table(a,b,c) values (6,2,3)
insert into table(a,b,c) values (1,7,3)
insert into table(a,b,c) values (1,2,8)

The "right" way to do this would be to take advantage of gadfly's
dynamic parameter/multiinsert feature executing

insert into table(a,b,c) values (?,?,?)

ONCE with dynamic parameters list

[(1,2,3), (6,2,3), (1,7,3), (1,2,8)]

which would run much faster than thrashing the parser
with the individual inserts above (with kjbuckets present).
In general dynamic parameters on repeated statements reduce
parsing and binding overhead (even for other types of statements).

However, I understand this may be hard to implement as
it would require special features for the gadfly "adapter"
not of value for the other adapters. Oh well.

Anyway, in future please post/forward/crosspost any gadfly
related issues to the gadfly list.  I just discovered a pile of
complaints on the zope list this morning and I found it
distressing.  I don't normally read the zope list.

Try:

or this:

Subject: [Zope] Using Zope with CORBA (new user question)
Message-ID: <199903042212.RAA16927@hog>

I have a long running process that will be started by Zope.  This
process has a CORBA interface that is implemented using ILU.  I would
like to be able to asynchronously have this process generate data for
Zope.

My basic questions are:
	o Can I have an ILU mainloop inside of Zope?  (I really don't
	  care if I have to hack Zope or if I can use an external
	  method.)

	o Should I fork/exec the long running process and give the
	  process a URL that indicates where the data should be
	  written?  (I can use pickles or sql.)

	o How do I tell Zope that new data is avaliable if the process 
	  is external to Zope?

Message-ID: <Pine.LNX.3.96.990304141142.8459C-100000@taos.kavi.com>

Ok, what's the trick to getting special characters to be converted to
their escape codes (eg. " to &quot;). This is particularly important for
forms in which the user may enter these types of character. 

For instance, if I create a property on a folder that is a string, and if
the string I enter has quotes around it... it doesn't show in the
interface the next time I go to edit the properties. For example, in
MCExam, the 2nd sample question has this as an answer "bar, spam". If I go
to the folder's properties to change it, it doesn't show up. In the source
it looks like: 

<input type="text" name="ans3:string" size="35"
   value=""bar, spam"">

Obviously, if I then save changes, the value is gone altogether.

Is there a way of automatically converting quotes and other special
characters to their escape codes (like the sqlquote method)?

Thanks,

Sorry, your ideas don't work either.

This time I get a NameError for mhost in the following code in
SendMailtag.py.  mhost is never being created.


        if self.mailhost:
            mhost=md[self.mailhost]
        elif self.smtphost:
            mhost=MailBase()

        mhost.send(self.section(md.this, md), self.mailto, self.mailfrom,

Are you the wonderful folk that manage the atmospheric database at

I do not know much about CORBA but you might find it helpful to check the
ZClient library that comes with Zope. You can use ZClient to script Zope
actions. In other words you can have your CORBA proccess running
independently of Zope and whenever there are available data you can call
Zope using ZClient and update whatever you need to.

Grovelling through the source I find something called html_quote in 
lib/python/DocumentTemplate/DT_Util.py, so I tried:

<!--#var nastyvar html_quote-->

Which seems to so the right thing in the generated source. I'm not sure
how to get at the equivalent method call, though.

Does that help?

(p.s. there's url_quote, as well)

I think we're trying to assign a string where a mailhost object is needed.
I'm not sure how to get around this, without an external method. Though
with an external method, it'd be pretty simple:

(warning: untested)

def get_mailhost(self,property_name):
	""" gets the mailhost """

	mailhost_id = getattr(self,property_name)
	return getattr(self,mailhost_id)
	
Or something like this... [shrug]

Both answers are much appreciated. Things start to clear up, but ...
As far as I understand zope it should also be possible to have forms send
data directly to external methods. How do I go abouth to make the argument
list in a python function so that it receives more than one 'form variable'.
1 is simple, but my form consists of 5. I get an error constructing the
python function to take 5 arguments. How is the 5 'variables' sent to the 
method? How do I get hold of the values each store?

Lotsa questions - probly me doing things the wrong way but - I'm learning:)

Yes. This is just what I was looking for.

This leads to a followup question/request for the group.

'manage_addProperty' calls various converters from ZPublisher.Converters
to format the properties values. Shouldn't html_quote be used when
formatting strings and text? This would be trivial to change. Would this
cause some problem I don't realize? If not, I'd like to add this to the
Collector for the next version.

Message-ID: <Pine.WNT.4.04.9903041647000.268-100000@rigoletto.ski.org>

I have a standard_html_header/footer pair which works much like that on
zope.org.

The header inserts a <!--#var sidebar--> in the left column.  The
sidebar DTML method is:

<!--#in expr="objectValues(['Folder'])"-->
<!--#if hidden -->
<!--#else -->
<a href="<!--#var id-->"><!--#var title--></a><p>
<!--#/if -->
<!--#/in -->

(show links to sub-folders which don't have the 'hidden' property set).

The above works fine in the toplevel folder.  In the subfolder, however,
nothing shows up, even though there are two folders which do qualify.

I'd tried originally to have it be a DTML Document and change the expr to
_.objectValues(['Folder']), but that doesn't work at all.

What am I missing?

Check if your DTML properly closes all tags. I had something similar
happening to me in a complicated DTML, when some condition failed to add a
</TABLE> tag. 

BTW you can use
<!--# unless hidden-->
...
<!--# /unless-->

Yes! This was exactly what was causing the error. I added a new 'System
DSN' which then showed up under IIS, and now I've got a shiny new and
perfectly functional Z ODBC Database Connection. 

Much thanks!

PS - Don't know if this info is helpful, but I noticed that (after I set up
a valid System DSN) when my attempt to add a new Z ODBC DB Connection in my
IIS/1.10.2 environ was flawed for whatever reason I would receive the
cryptic 'HTTP Error 400 - Bad Request' from IIS. After some very quick
poking around I noticed that even after selecting a valid dsn, flaws such
as trying to add a connection with an ID already in use, or entering an
invalid connection string would give this 400 error - whereas in my
ZopeHTTPServer/1.9 environ I would receive relevant and helpful error
messages in such situations... Wish I knew more about how to help fix...

Thanks to both John and Ronald for their kind assitance. I have made it
past
my original error and got everything compiled correctly. However, my
general
Newbieness is still coming back and biting me on the you-know-what.

The instructions state that I should start python, and then Import the
MySQL
module to make sure it works. When I do, I get yet another error.

Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: libmysqlclient.so.6: cannot open shared object file: No
such
file or directory

The file does exist, so I am once again stumped.

Thank you for your continued assitance.

Where exactly is the file?

find out by doing a locate 'libmysqlclient'.

Let's assume that it is in /usr/local/mysql/lib.

The easiest way to accomplish what you want is this.

1.    cd /etc
2.    vi ld.so.conf
3.    Goto the end of the file and add a line that says
'/usr/local/mysql/lib'
      replace this with the exact location of you libmysqlient.so.6
4.    save the file
5.    run 'ldconfig'
6.    run 'sync' twice, this just makes sure all changes are written to the
disk.

This adds the mysql lib directory to the lib search path.

Why not use a MailHost Object? On that object you can then set the
appropriate SMTP Host, even from DTML code..

Yes, because you sometimes (most of the time, really), want to have the raw
input from the user. If you then use this raw input in HTML again, only
*then* should you quote out any HTML. Besides, what if I want the data to
be URL quoted? Or SQL quoted?

Just a quick shot: Could it be that the value 'hidden' is aquired from

I did notice today that IIS 4.0 seems to be the cullprit. Whenever Zope
returns a 400 error (like 'sorry, an error occured') IIS mangles that into
the 400 Bad Request error.
This means the traceback is also gone. *grmbl*. Just try and add a
Principia Draft and not specify an ID, and compare this to the message
returned when using ZopeHTTPServer. I think I'll switch to ZServer.

Maybe this should go into the FAQ... I'll cc to ZDP

BTW, I hereby retract the bug I reported to the Zope Collector regarding
ZODBC connections being broken. I forgot to fill in the ID :|. IIS mangles
the returned errormessage.

What is the procedure for retracting bug reports? mail support@digicool.com?

Message-ID: <Pine.LNX.4.04.9903050506001.1539-100000@gaaros.msrc.sunysb.edu>

Zopistas

I have encountered problems mainly associated with ZServer and ZAP:

I am using Zope-1.9.0 and the preconfigured Apache server to run my Zope
site. Last night (a couple of hours ago!) I installed ZServer. It wouldn't
run and I had to add the following to start.py to fix it:

import sys,os
sys.path.insert(0,os.path.join('..','lib','python'))

Later on upon entering the management screens I noticed that the id of the
top level folder dissappeared which caused the paths to my objects to
change. With ZAP (the preconfigured apache) I would visit:
http://www.gaaros.com:8080/Gaaros/ to get to the top level directory but
with ZServer is: http://www.gaaros.com:8080/ which spoils all kind of
links that people have on my site.

Switching back to ZAP I got the following error:

  <FONT SIZE="+2">Temporarily Unavailable</FONT>
  <P>
  The resource you requested is temporarily unavailable - please try again
later.
  </TD>
</TR>
</TABLE>
(102) failure during connect
<!--
No such file or directory
pcgi-wrapper-version 2.0a5
-->
</BODY></HTML>  

Seems like ZServer changed my root id from "Gaaros" to nothing.
I called PickleDictionary on Data.bbb directly from python but I could not
even see the subobjects. BTW can the Zope Data.bbb be accessed directly
from PickleDictionary??

Also trying to shut ZServer from the control-panel results in a core dump.

Ok enough for now, its very late and I cannot think anymore.

If anybody has any clues about the root object id problem please let me
know.

Thanks

Pavlos

No problem. Basically I filter all emails arriving in my personal account
that contain FAQ in the Subject: field. As I am subscribed to all the Zope

This is a poor answer (as most here know I don't have the mental
horsepower to provide good responses :^), but...our _intention_ over
time is to have "ZServer" allow objects to be published via PCGI,
FastCGI, HTTP, FTP, and CORBA simultaneously.

Ideally we'd get some kind of Python implementation into the Medusa
handler layer.  Obviously this approach has some serious drawbacks...

Anyway, I realize that I'm not providing much of an answer, so sorry :^(

Right, understood.  We had to spend a lot of time figuring out Gadfly in
order to host it inside Zope.  Thus we labeled it "Demo".

I imagine that it is best for everybody if we take Gadfly out of the
base Zope and make it an external, no-warranty package like the MySQL
support.

This is really weird, it just reminded me of a (rather pathetic) dream I

My DreamTV must be picking up the wrong channel.

I've been awfully interested in XML in the last few days.  Can you
describe what user-visible benefits PHP delivers due to its integrated
XML parser?

Additionally, we are working on Zope searching for a consulting project
right now.  Actually it is Zope Cataloging.  It's still a
consulting-only option, but plans are that eventually it will go "below
the line".

I *think* I have some good news to report on this, but before I squawk,

There have been a lot of suggestions on this one.  Here's another one: a
command-line program that takes everything out, such as the wget
program.

I'd like to have this as well.  I've been doing a lot of thinking about
this lately.  It is a bit more complicated than expected, though...

This is the main reason I replied.

Having Zope as a free and Open Source(tm) platform is the heart of our
business plan.  A closed Zope would basically mean we start over
completely as a different company.  Thus, closing Zope is roughly
equivalent to closing our company.

With _that_ said, we still need to provide some assurances that we won't
legislate the connection between Zope and DC.  First, we are trying to
keep some arm's length distance between zope.org and Digital Creations.
We hope to formalize the way the community participates in the platform.
We expect to make it lucrative for other businesses to participate.

At the same time, we intend to pursue commercial opportunities atop the
platform for vertical applications.

Ultimately this is the same question put to Netscape regarding Mozilla
during the AOL talks.  The answer is simple: "The genie is out of the
bottle."

Since it is open sourced, Digital Creations must *earn* its stewardship
of Zope.  If we don't we'll become less relevant.

Earning the community's enthusiasm is pretty simple, I think.
Unfortunately we aren't doing a good job right now, though we are trying
damn hard.  But we'll keep trying...

In the meantime, I'm absolutely ecstatic to see folks in the community
step forward over the last month and lead the way.

Yep, the zope.org machine has five virtual hosts.

Previously answered.

Ditto.

We put them in the database.  The 3 Mb Zope binaries are served out of
the database, the PDF files are served out of the database.  This works
so well I don't even think about it any more.

hmmm. That's interesting because it works just like oracle or it
should,unless there are more bugs you haven't passed on to me.  Let me know
what caused the problems.  Basically any non-conformance with the db-api
is a bug.  Please report it to the gadfly-rdbms list.

Yes, this is fine.  BTW, it might be hard for your existing customers to
upgrade to Gadfly 1.0 since I think the db file formats are different

I would suggest, first off, to use 1.10.2.  ZServer is being developed

Yes, there were discussions on this in the list about this problem.
Someone needs to go back, rassle up the discussion and submit it to the
ZDP.  Looks like you found the fix.

Hm.  Is your Zap .pcgi file named Garros or does your RewriteRule look
for Garros and then call PCGI?  If so that is why you need to use Garros
to reach the server.  ZServer can server right out of Zope and doesn't
have this problem.  Your description makes this sould like it is a
production site, I would not suggest running ZServer on a production
machine as it is alpha and still buggy.

This error comes from PCGI.  It can't find your .cgi file so Zope isn't
even being launched.  Did your zap.conf file change (specificly the
RewriteRule)?

You can open a Data.bbb file into a PickleDictionary, but you won't see
anything useful unless you really know what your doing.  The Database
itself is not a Pickle, it is a database of Pickles.  I have attached a
small 5K script that will be released with 1.10.3 which paruses the
database and generates reports.  In the future we are intending it to
translate the entire database into XML for transport. (Note, we do not
intend to use XML as the db format)

I suspect this is because you are using 1.9.0

It's allways worth while! :)  I think the point paul was trying to push
is that we are interesting in publishing our objects over various
transport protocols.  If you want to look in this direction, probably
the best idea would be to write a Medusa handler.  Check out Sam's site
at:

http://www.nightmare.com/medusa

There currently exists an ftp and http medusa handler for Zope, which
you can look at in the latest ZServer alpha release availabe at
zope.org.  I'm not sure is there is a Medusa CORBA handler or not, I
suspect not, but maybe there's some type of CORBA out there written in
Python?

Yes.  ZServer really restores Zope's original intent from the Bobo days:
publishing objects through a variety of protocols.  I think ILU support was
once attempted back in those days.  However, a Bobo app at that time could
only have one publishing mechanism (ie, CGI, PCGI, FastCGI, ILU, etc...).
ZServer allows for multiple publishing mechanisms in the same application,
allowing access to the objects through the web, through FTP, or through any
other protocol developed for ZServer/Medusa.

Subject: [Zope] Documents for web and paper
Message-ID: <012c01be6729$74f6bd40$0201a8c0@hawkeye.bob.oc>

I'm looking for the best way to store and
retrieve documents with these requirements:

SPECS
*Easy storage and retrieval on the web
*Pretty printing on paper
*Easy simple collaboration (no checkout)
*One BASE format for both web and paper
*Base format *could be* edited with
   Word or WP
*Preserve text markup:
   bullets, bolds, underlines,
   tables, graphics, links...etc.
*Search by keyword
*Search by full text


*******
I look forward to comments and
Ideas on implementing this in ZOPE
Perhaps some of this has been solved
already and I don't know it.

EXAMPLE:
Say you have a small book/article
 that is fully contained in a WORD
or WP file.

It has chapters and sections:

Chap1 Plants
      Section1: Trees
      Section2: Flowers
      Section3: Vegetables
      Section4: Fruits
Chap2 Animals
      Section1: Dogs
      Section2: Cats
      Section3: Fish
      Section4: Humans

Ok, as a paper document in the
word processor it is laid out *nice* with
a new page for each chapter, section,
and subheadings for groups of paragraphs in
each section. It prints *nice* and can
even have a table of contents and index.

For the web, the whole book could be
one LONNNG web page.  Ugly and it
doesn't work well.

Ideally on the web each chapter and section
would be navigable with a left hand frame
like table a la http://www.zope.org.  Then
sections can be placed on separate pages
on the right.  This means that the one source
document becomes multiple html
"files" on the web site.

*Tree Navigation
Ok, for tree navigation like
http://localhost:9673/QuickStart
Each Chapter and Section becomes a folder and
the text from each section is contained in the same
named: "dtContent"  as in
...9673/QuickStart/Outline/Applications/External/dtContent

While the tree is nice,  and separate html "files" make the
website better,

*REVISIONS with TWO OUTPUTS

How do you do:
Make revisions to the source document in word/WP
and have it FLOW automatically to html format or
tree format for the web?

*Perhaps* XML could come to the rescue as holy grail
to help solve this problem???  I understand the idea
of mark up but how does it solve the problem of two outputs?

Can you have a template that automatically chops up
the SOURCE into the appropriate folders/files etc and
feeds it to ZOPE?   Can this or another template reformat
for pretty printing including page numbers that are
updated based on the planned printing?

Maybe I need to reconsider how documents are
stored as source, i.e. not Word.  And if not,  what
tool or mechanism would be best?  Maybe the
NATIVE source could flow to Word/WP or
via a template making for pretty printing.

Maybe for simple stuff, the source could be
simple text entered on a webpage or sent
by e-mail with *simple* markup and parsed
automatically?

*KEYWORD SEARCH
Ok, on the web (and Zope), the benefit is it's
searchability:  Do we "hide" keywords in the
source somehow and in addition use Chapter
and Section titles as Keywords?

Search for: "dogs"  gives a result of
Chapter 2 Section 1 in the example as
one entry.  Additional entries might
be lessor cross references such as
a keyword "dog" in the Section 4 humans
as "man's best friend".

*FULL TEXT SEARCH
Ok so we search for the word "Daisy"
and this word is found in the text in
sections: Flowers, Dogs (as a pet name)
and Humans (as a proper name).

The result is then three line entries that
take you to the words.

*Zope IDEAS for this?

I assume that it would be best to store
the documents and source in the ZOPE
database rather than an external datasource.

Thanks for any input on this

Nah -- getting rid of the hidden test doesn't change a thing.  Sorry I
confused the issue with that.

I think my problem has to do with my lack of understanding of the
interactions between acquitision, DTML Methods, DTML docs and namespaces.  
I just noticed that the standard html headers and footers are methods.  
That means, if I understand the earlier email, that the default namespace
in them is that of the thing they are contained in.  So, in my case, the
top-level Folder.

Now, in the sub-folder, the standard html headers and footers are acquired
from the toplevel folder.  The standard header does a #var sidebar, which
also lives in the toplevel folder, and that gets included fine.  Within
that sidebar, I'm not sure what the default namespace is -- my fuzzy
understanding makes me think that it should be either:

  a) the / Folder (the 'physical' container for the DTMLMethods)

  b) the sub Folder (the container for the thing which did the
     aqcuisition, namely the index_html DTML Document.

Problem is, neither of these makes sense given what I'm seeing.  If it was
a), I'd expect the 'objectValues()' call to return the same list of the
subfolders of the toplevel folder every time.  If it was b), I'd expect
the thing to work and give me the subfolders of the subfolder.

Let me try to summarize the hierarchy:
  
   /
     - index_html  (#var standard_html_header...#var standard_html_footer)
     - standard_html_header (#var sidebar)
     - standard_html_footer
     - sidebar
     SubFolder1/
     SubFolder2/
        - index_html  (#var standard_html_header...
                       #var standard_html_footer)
        - SubSubFolder1
        - SubSubFolder2       
    
The top sidebar shows SubFolder1 and SubFolder2, the /SubFolder2 sidebar
doesn't show a thing.

PS: Thanks to pavlos for pointing out the #unless tag.

PS: For some reason the title of the root folder is "Zope" in the
    properties tag but doesn't show up in the tree or in the pathlinks.
    Anyone have a suggestion?

Try: <!--#var "sidebar(PARENTS[-1],REQUEST)"-->

This will call the method using the root folders' namespace, thereby
showing all qualifiying subfolders regardless of where the method is
called from. You might have to modify your method to construct absolute
URL's.

Thanks!  What I actually wanted was sidebar(PARENTS[0], REQUEST), but you
pointed me in the direction I needed.  Now I have to understand it, but
that's much easier with working code. 

This also led me to find a bug.  I was wondering why the REQUEST parameter
was needed, so I tried to remove it.  The next time I loaded a page
calling this code, the ZServer process died with the Win32 equivalent of a
segfault.  Is it just me?  I don't dare try it on another Zope server =).

Yeah, I already figured out that the problem was actually in the
OFS/properties.dtml file (I moved over to the zope-dev list, as I realized
this thread really belongs there). In properties.dtml the 'string' type is
listed twice:

  <!--#if "type in ('string', 'int', 'long', 'float', 'date')"-->
  <input type="text" name="<!--#var id-->:<!--#var type-->" size="35"
   value="<!--#var "_[id]"-->">
  <!--#elif "type=='string'"-->
  <input type="text" name="<!--#var id-->:string" size="35"
   value="<!--#var "_[id]" html_quote-->">

'string' needs to be removed from that first list. I'll be submitting this
to the Collector.

I'm new to Zope. I'm very excited about it's potential, but my first
impression is that I will need to master Python in order to use it. I
believe Python is an excellent language, but I do not have the time to
learn it. Several questions about this:

- Can I achieve anything useful in Zope without touching Python? I can
learn DTML, of course.

- if so, what I can and what I cannot do without Python?

- could I, for instance, do something like slashdot.org without Python?

- is there a plan to give Zope features (or ready-made
modules/factories) that would completely eliminate the need to work with
Python (for certain tasks that can be automated or turned into
templates)?

Hi Paul and Zopesters,

I found a great description about XML in:
"20 Questions on XML"
http://builder.com/Authoring/Xml20/index.html

On Paul's Zope roadmap: (Jan 18th)
http://www.zope.org/Information/Roadmap

"(2) XML. Zope is a great fit for XML, even better 
with the machinery from Tabula going in. We also 
see XML becoming the basis for other initiatives, 
such as WebDAV and RDF. However, we just can't 
squeeze out the time to dive in deep. Rather, we'd 
love to see more community progress like that 
which popped up this weekend."

I did a search for postings that had "XML" 
in the subject and found
55 messages in ~6 threads between
Jan 8th and Feb 2nd

Other messages have "XML" in the body.

Hopefully we can get some OUTLINE of how ZOPE
and XML can work together.  --- A framework for
further discussions.

You do not need to know a single line of Python to use Zope.  But
learning Python is a pleasure, not a chore.

You can do just about anything with DTML.  In fact, most 'Products'
(read that, 'Zope Extnesions') are mostly DTML.  If your not writing a
Product then you can stay entirely in the domain of DTML.  DTML does use
a small bit of Python in itself, these are called expressions.  For
example, if you had an integer called num you could use:

<!--#var num-->

to 'render' it in your web page.  To get num + 1 you would use:

<!--#var "num + 1"-->

The contents of "" is a python expression.  But it's not a python
program.  If we didn't use Python we'd of had to have come up with some
other language like way of doing this that you'd have had to learn
anyway.

> - if so, what I can and what I cannot do without Python?
> 
Python is used for the following:

To write Products. This is hard core development.

To write External Methods, which are used to hook special or
wierd/pre-existing python functions into Zope.  This is rarely necesary.

Yes.  There may be a 1% slice of something like slashdot needing a bit
of Python.  But remember, slashdot is a huge application written
entirely in Perl.

Yep.  These are called Zope Classes.  They are still in-house here at
Digital Creations because we are still debugging/figuring them out.  A
Zope Class lets your create your own objects that can be added into Zope
without writing Python code.

More information on my front.. I've been fiddling around a bit trying to
find out what is going wrong..

I'm using ZServer/Zope 1.10.2 with ZMySQLDA that I just downloaded 2 days
ago.

The traceback is as follows:

<!-- Traceback (innermost last):

line 384 of DA.py -- __call__ reads:
query=apply(self.template, (p,), argdata)

I added a bit of debugging code and was able to a take a look at some of
the data being passed around:

argdata was {'sql_delimiter': '\000', 'client': '1', 'pend': '1',
'pstart': '1', 'sql_quote__': }

This is starting to confuse me because simple queries work fine within
Zope, its only the query that I posted in my previous message that seems
to be fowling things up.

I'll keep slagging away until either I figure it out or someone tells me
its not something I've done and that I should submit it to the Collector
:)

Subject: [Zope] DatabaseError: Corrupted data record...
Message-ID: <199903052137.VAA24776@finan.ncl.ac.uk>

Hi all,
Firstly, I'd like to thank everyone for the detailed replies I got to my 'Tough Questions' post.
I'll reply individually to you all and try to answer some of the questions that *I* got asked, but as 'they' say...

"...there is one small problem!" (MPaTHG)

My database has got nuked.

I don't know how it happened, but this is the tail of my serve.errors file

  File "lib/python/OFS/Application.py", line 319, in open_bobobase
    Bobobase=Globals.Bobobase=Globals.PickleDictionary(
  File "lib/python/BoboPOS/PickleDictionary.py", line 159, in __init__
    db=apply(DBType,(),storage_options)
  File "lib/python/BoboPOS/SimpleDB.py", line 221, in __init__
    self.open(file_name,create,revision_time,meta_index,read_only)
  File "lib/python/BoboPOS/SimpleDB.py", line 287, in open
    try: self.index,self.pos=read_index(
  File "lib/python/BoboPOS/SimpleDB.py", line 1365, in read_index
    raise DatabaseError, ('Corrupted data record at %s' % pos)
DatabaseError: Corrupted data record at 1087646

Trying to 'start' the server again just results in the serve.errors file being touched.

As you'll know from my 'Touch Questions' post, I'm a novice in Zope (but I've bought the Lutz 'Programming Python' book, have two more on order and have been reading and rereading the docs all week...so I'm learning fast), but this has me stumped.

I haven't got too far into my Zope 'career' yet, so I won't be devastated if I have to replace the database from scratch (how do you do that by the way?), but I'm sorta worried about the way that all my work seems inaccessible to me now.

any and all help would be ... appreciated.

Okay, now it makes sense.

Is 'client' a reserved variable?

If so, perhaps a warning would be nice if you attempt to use a reserved
variable as an argument to a SQL method.

Argh.. so I got that fixed and now I am getting another traceback when
testing the SQL method!

I can't believe it :)

Here it is:

Message-ID: <Pine.WNT.4.04.9903051334580.264-100000@rigoletto.ski.org>

I need to detect not only whether a list is empty (that's easy with the
#if tag for example), but also whether all of the elements in the list
have a property. In Python, one could do this with something like:

  empty = 1
  for element in theList:
    if not element.hidden: empty = 0
    print element
  if theList and not empty:
    print "no non-hidden elements"

What's the equivalent DTML?  Can one create a variable in DTML?

Can anyone tell I miss my Python when writing DTML? =)

I didn't try such a thing before. But because the Zope
database is always only appended to (if I'm understanding right),
you might try to truncate the file upto that offset and see
if it is working again? (please keep a backup :-)

Subject: [Zope] Authentication and Zope.cgi
Message-ID: <199903052211.PAA16445@daikon.tuc.noao.edu>

I'm in need of a bit of clarification about how Zope starts up and when
it decides to do its authentication and why.

I'm running 1.10.2, solaris 2.6, apache, pcgi, netscape 4.07.  When I request
mymachine/Zope/manage   I do indeed get the normal management screen.
I haven't been asked in some time for a password, which suprises me;
the 'access' file exists and (but?) hasn't changed since installation.

I'd really like the root folder to say something other than Zope, so
I added to Apache a second rewrite rule that substitues 'mpg' for Zope
in the two places (restarted Apache), and copied Zope.cgi in cgi-bin
to mpg.cgi .  These two cgi files are identical so they point to the
same /var directory.

If I try   mymachine/mpg/manage  ,  I get an authorization failed box,
and upon clicking 'retry', I get the usual authentication box with
the correct 'access' user entered.  I type in the correct password and
the system fails again ("You are not authorized to use this system.
Username and password are not correct").

So, I'm very curious as to what's going on ... and I wouldn't mind
learning how to change the top of the root name as well.

OTH if you have most of your code written in DTML it is so easy

What version of Zope are you using? What OS?  Were you using NFS? MySQL?

Please send *in private mail* me a gzipped tar file (or Zip file) 
containing the Data.* files from your var directory.

Any other thoughts you might have regarding events leading up to this

Good point.  I should have mentioned that as a quick

But please send me the file before you truncate it. :)

Hmm. I want to create a variable whose value is given by another value.
Doing:

<!--#with "_.namespace(foo=<!--#var id-->)"-->
<!--#var foo-->
<!--#/with-->

doesn't make it through the parser.  

I've tried adding various quotes to no effect.

I think I'm going to work on understanding ExternalMethods -- this syntax
is not made for me. =)

Why does my ZMySQLDA Z SQL Method die with a KeyError: unhandled message?

Well, I was looking at the code for the MySQLmodule and it appears that it
has problems handling some fields.

This appears to be a limitation of the MySQLmodule.  It currently does not
handle the LONGLONG datatype longer timestamps use.

At least I assume its the LONGLONG that is messing it up.  I haven't
looked into that much detail to be honest.  

I'm not quite sure if this is something that should be included in the
FAQ, or considered a known bug, or submitted to the Collector?

Thanks,

This surprises me, since as far as I can see, one is always asked for password
accessing /Zope/manage. Does netscape 4.07 automatically go through authenticate
procedure?

There are at least two possibility.
1) Misconfigured rewrite rule.
2) mpg.cgi is not altered suitably.
(oh, 1+2 gives the 3rd possibility).

I was in a similar situation a few days ago. Now one of apache virtual host on my
linux box has 1) ordinary apache site tree, 2) experimental(read 'for play') Zope
site under  hostname/Zope/ (through Zope.cgi)
3) public Zope site under hostname/public/ (through public.cgi)
If this is similar enough to what you want achieve and you are desperate enough,
just mail me your rewrite rule and Zope.cgi & mpg.cgi with sensitive parts
altered suitably. But be aware that I am new to rewrite rules and pcgi
world(hence if you are desperate enough).

This is easy. Just edit BOBO_REALM (NAME?) in your *.cgi file.

LEE Kwan Soo.

ps.  my Zope's have their own var/Data.bbb but you want your Zope to point to the
same var/Data.bbb. Oh this seems far beyond the capacity of mortal being. If you
really want need this setting, I guess, the easist way to achieve it is getting
Zopal blessings from DC(i.e. make a consulting contract with DC).

I'm guessing that the parsing of the tokens picks up on underscore

Ouch!, what we do is save the word docs as RTF. A free program (written in
Omnimark) called RTF2XML then trundles through it and creates well-formed
and valid XML. I then pass it through another Omnimark program that I wrote
that turns it into XML that is more suited to what we want.


>I've been awfully interested in XML in the last few days.  Can you

Background:...
PHP is a (non OO) server-level scripting language, usually delivered as an
Apache module, that has it's roots in C, but with some of the arcane bits
removed. It's database integration is very good. The authors have recently
built the (almost XML-industry standard) parser Expat into it.
...

From my point of view, having the XML parser in PHP meant that (a) I didn't
need to call Perl CGIs (with all that overhead), (b) I'd understand the code
a bit (I *cannot* do Perl!), (c) there might be a performance boost from
having the parser in the Apache Module and (d) I'd be able to map XML
elements such as <topic> ... </topic> into HTML <div> ... </div> tags or RTF
control codes (all of which would be read from a user-defined database) -
thus leading to the 'Holy Grail' (ouch!) of being able to render the
documents into whatever form the end-user wanted. As well as that, using XML
means that I can select all <topic> .. </topic> tags that match a certain
criteria (eg, all first-year study guides that mention cell biology) from
*all* our study guides and create a 'composite' document that would be
passed through the XML 'converter' to get custom HTML and RTF docs.

Of course, once I 'got into' XML I found out that just having the Expat
parser around didn't necessarily mean I was going to get all that for
free...ie how 'do' you 'search' an XML document to get those matched <topic>
tags (and possibly their children). Enter XQL and it's friends, DOM and XSL.

XQL (Perl module based on a W3C recommendation) works, but it's slow. 

In short, I was at an impasse. The level of work needed to incorporate XQL
into PHP (as a CGI) or (gulp) rewriting it as PHP was just too much.

I installed the XML-Config product for Zope and my appetite was whetted. I
read about the XML-sig and downloaded the XML-0.5 toolkit from python.org. I
tried one or two examples out ... and my jaw literally fell open. By the
time I'd looked in the 'dom' directory I was almost gibbering. This was
something I felt I might be able to understand (and definitely use).

Ooops...I'll shut up as I'm waay of topic.

No, but I've spent the last week muttering 'ok, I can use UserDB to
authenticate against our StaffDB and allow per-user access to the file
upload area', 'yeah, should be able to rewrite my PHP Multi-Choice Question
engine in this DTML gubbins', 'ok, I'll pull in the Perl script that does
xxx by using a redirect' and the like ... which is probably more scary!

Simply this: 
Zope seems to do just about everything I need (which is basically to provide
a *framework* for the Electronic Curriculum - others will fill in *and
manage* the content). I can then concentrate on providing features that
people need and 'rolling them out' to the users of the systems, confident
that they will integrate into the whole system. 

I think it's a paradigm-shifty thing more than anything else. Everyone in
our group *knows* that an .htaccess file allows access to the files in that
directory. They all have at least a basic grasp of CGI programming and all
recognize the mapping between files in a unix file structure and their
representations as web pages. People using Zope will have to break that
habit of logging in to change a file ('cos it ain't there!).

(for the time being, I've desubscribed from the PHP-lists to give me more
room to think!...)

Subject: [Zope] Subfolder Access?
Message-ID: <3.0.6.32.19990306180733.009318b0@hito.eccosys.com>

I think there must be an easy way around a little trouble I'm having, but
it's had me stumped for a few days and I can't find any mention in the
list/docs.

From a dhtml method I want to access a subfolder's sql methods, which is
easy enough using <!--#with SUBFOLDER--> <!--#/with-->. The problem is,
because of the amount of methods involved and in order to keep things
flexible I want to add the <!--#with--> to a standard_header, and the
<!--#/with--> to a standard_footer. Of course, Zope nixes this. So I was
hoping there was an end-run around this dilemna - some other way to give
access to subfolders. 

I've tried including the opening and closing WITH's in the same document
surrounded by IF's with no luck, and have been wondering if there's a way
to set a folder property to accomplish this...

You cannot nest DTML but you can use _[] to access the namespace. For
instance you could do:
<!--#with "_.namespace(foo=_['id'])"-->

I too miss Python when working in DTML.  But in this case, I think that the

Subject: [Zope] Creating Zope a zope application
Message-ID: <19990307130236.A532@RaVER.duck.org>

Hi!

I'm reading 'A technical introduction to object publishing with Zope'.

The doc says 'Creating a Zope application is simply a matter of creating a
regular Python module containing the objects to be published, and placing
this module along with some Zope-provided support files in the appropriate
place on a web server'

The doc continues to say that the zope documentation covers this prosess,
but I'm not able to find it. So my question is - what are those
zope-provided support files, and where am I supposed to place those file
along with the python module that I've created?

Hi,
I've read on the zope-dev list that Zope is not multi-threaded.

Does this have any ominous implications for server performance? I believe it
means problems for people writing products, but does it give problems for
folk using Zope in an 'install products and use them' scenario?

many thanks for any thoughts,

We can discuss this now, but in a short while it won't really matter.
Zope as we know it now is not 'multi-threaded'.  The real issue
concerning Zope is one of concurrency, since the 'threading' of requests
is ussualy created by the web server (Apache using multi-processes or
Medusa (ZServer's) use of select(), neither of which use actual
'threads').  There are two areas that we are working on to make zope
concurrent.

The Database:
	There is a new version of BoboPOS, called BoboPOS3.  It is
currently alpha.  BoboPOS3 supports concurrent processes opening,
reading and writing the Object Database.

'Concurrifying' Zope:
	Concurrent programs have to be careful about some issues.  In
particular, the use of global data.  These can sneak in on you in wierd
ways.  For example, in the regex python module (yes, regex has been
depreciated for re, but for now regex is faster) certain uses of
compiled reg expressions don't work when two 'threads' enter the same
expression.  Also, there is an issue about passing mutable objects as
default arguments to methods.  To be truely thread safe, default
arguements need to be immutable, or mutable arguments can only be used
in immutable ways.

These are, as you said, developer issues.  Product developers have to be
careful not to block Zope for long periods of time.  People in the
'install and use them' scenario should not use these types of Products
unless they are sure the block times are low, and product developers
should be very, very careful about moving their software out into the
world if the product blocks.  It should be made clear to the user that
this software could stop up the whole works.

Why is won't matter soon is because we are working on making Zope fully
concurrent.

Message-ID: <l03130300b309086b41cf@[206.40.158.77]>

Advice needed, opinions wanted.

I have a situation where there is a group of users with both a private
space and a public space. The users homepage is considered private with the
public space where all anonymous viewable docs are held. I have two
thoughts on how to do this, Zope is capable of either method, I'm curious
which method everyone else thinks best, and why.

First method;
community folder (contents public viewable by permission)
     user_folder (contents not public viewable by permission)
	users manage page (not public viewable by aquisition)
	users public folder (public viewable by permission)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by aquisition)

Second method;
community folder (contents public viewable by permission)
     user_folder (contents public viewable by aquisition)
	users manage page (not public viewable by permission)
	users public folder (public viewable by aquisition)
	     public_html (public viewable by aquisition)
	     public2_html (public viewable by aquisition)
	users private folder (not public viewable by permission)

Both have advantages and disadvantages, either way I end up with on - off,
off - on, in the permissions hirearchy. Anyone have a good argument for
either method?

Subject: [Zope] Why doesn't this loop over files?
Message-ID: <v04104422b3094ee5414d@[128.240.198.13]>

Hi,
I've d/led the ZopeDemos folder, installed it and started learning 
more about Zope, but there's something happening that I'm not sure 
about.

The 'looping' example doesn't seem to iterate correctly over new 
additions to the folder. The DTML is here:

<!--#in "['Document','Folder']"-->
<!--#if "objectValues(_['sequence-item'])"-->
   <H3>Objects of type <!--#var sequence-item--></H3>
   <TABLE BORDER=1>
   <TH>Id</TH><TH>Title</TH>
   <!--#with subFolder-->
      <!--#in "objectValues(_['sequence-item'])"-->
        <TR><TD><!--#var id--></TD>
        <TD><!--#var title--></TD></TR>
      <!--#/in-->
   <!--#/with-->
   </TABLE>
<!--#/if-->
<!--#/in-->

If I create a new DTML method or document in the folder 'subFolder', 
it isn't recognised. I've even copy/pasted the documents that do work 
into the subFolder with no joy. Curiously, new folders *are* 
recognised.

My Question is: What's preventing Zope from reading *all* the 
Documents in the subFolder?

This would be the core of my first real application in Zope (a 
resource upload/download facility for staff here) so any advice would 
be appreciated.

thanks
tone.

Definitely. We have dozens and dozens (eventually hundreds) of files 
(QT movies, PowerPoints, Word Docs and the like - the mean size is 
about 600k-1Meg, but we have quite a few monsters at 6-7 Megs).

This would be excellent news for us.

Does this ensure that MIME types are kept with the document, so that

Ad-hoc Zope FAQ version 0.1.1

    The Zope Documentation Project has its own mailing list

    related communications. Please do not send your messages (such as

    Please join and help us document Zope!

Note on the categorizing of this FAQ:

    This FAQ is a FAQ in progress. It is uncompletely unstructured;
    unrelated questions are mixed haphazardly. If you feel the calling
    to help categorize the FAQ into sections, or if you'd like to
    maintain a particular FAQ section, please mail to the ZDP
    list. Thank you in advance!

Note on the use of StructuredText:

    See the (currently) first FAQ entry for information on how to
    render this FAQ into HTML using Zope. For more information on
    StructuredText see::

        http://www.zope.org/Documentation/Reference/StructuredText

    but this link is currently not completely up to date; see the
    comments in 'lib\python\StructuredText\StructuredText.py' for the
    current documentation.

* How do I render the Structured Text FAQ into HTML cleanly? (in Zope)

    When including Structured Text (STX) from a DTML Method into
    another Document with the 'fmt="structured-text"' attribute, it
    will be quoted twice. This is because the '__str__' method of the
    'DocumentTemplate.HTML' class automatically quotes its HTML when
    called.

    You can work around this by calling the STX document's
    'read_raw()' method to get the unquoted version.

    This way we can use unquoted Structured Text examples in our FAQ::

        <!--#var "FAQ_Document_stx.read_raw()" fmt="structured-text"-->

    Note that if the STX comes from a property the 'read_raw()'
    workaround is not needed.

* How do I return an image from an External Method?

    Example (for a png image)::

        def foo(self, RESPONSE):
            # set the header
            RESPONSE['content-type'] = 'image/png'
            # return the actual image data
            return mkimage()

    Another way to set the header information is::

        RESPONSE.setHeader('content-type','image/png')
  
* How can an External Method refer to the objects in the Zope app?

    Use an External Method that gets passed 'self'. 'self' is your
    hook into Zope world. From 'self' you should be able to get
    anywhere you'd like to go. 

    'self' is the folder in which the external method is
    called. External Methods are methods of Folders. Since External
    Methods are acquired, self is not always the same Folder in which
    the method is defined--it may be a child Folder.

* Is there any way for External Methods to access files on the
  filesystem of the server?

    An External Method can access anything on the server computer that
    the Zope process has access to. Therefore, an External Method can
    do just about anything a Python program can do. This is both a
    power and a liability.
 
* Can I restrict what an External Method can do? Is there somekind of
  sandbox environment for External Methods?

    Right now there is no sandbox execution environment for External
    Methods. An External Method has access to everything that the Zope
    process has access to. This is one of the reasons why External
    Methods are required to be defined in the Extensions
    directory--it's easier to keep an eye on them there.

* How do I call an external method from DTML?

    Use::

        <!--#var "external_method_name(arguments)"-->
   
    to call any External Method in the folder (or acquired by the
    folder). The more explicit alternative is::

        <!--#var expr="external_method_name(arguments)"-->

    The rule is that anything between double quotes in the first
    argument of the #var tag is interpreted as an expression
    attribute; a first argument without quotes is interpreted as a
    name attribute.

* In a DTML expression, how do I access variable names with a '-' in
  them? (such as 'sequence-item')

    Any variable name (including those with '-') can be accessed in
    the '_' namespace. This contains a dictionary of all variables in
    the default namespace. To access 'sequence-item' you therefore use::

        _['sequence-item']

    Another possibly is to use '_.getitem()', like this::
   
        _.getitem('sequence-item')

    The difference is that the first renders 'sequence-item' through
    DTML, whereas 'getitem()' does not; it returns the raw value of
    'sequence-item'.

* How do you safely do a backup of the Zope database? ('data.bbb' in
  the 'var' directory)

    In Zope 1.10 and later, you can simply back up the
    data.bbb. Because of the way the file written (all write
    operations are appends), it is highly unlikely for a backup file
    created directly to have a problem. If the database is being
    written while the file is being copied, then the Zope may discard
    the last transaction when reading the copy, if the last record is
    incomplete.
 
    Alternatively, you could export the entire site and backup the
    export file. This won't be a full backup however, as it won't
    contain old revisions of objects.

    Yet another alternative is to (mis)use the Pack operation (in the
    Zope Control Panel, database management). Pack will create a
    Data.bbb.old backup copy of your file before packing (for safety),
    which you could then back up. To exploit this side effect you
    could do a pack that says something ridiculous (like pack anything
    older than thousand days).

* How do I pass a non-form variable to the next requested URL?

    Use Hidden fields within the form::

        <input type="hidden" name="varname" value="<!--#var varname-->">


* How do I define a variable for use in a document

    Set it in REQUEST::

        <!--#call "REQUEST.set('varname', value)"-->

* How do I tell the tree tag to show only Folders?

    By using the objectValues function in the branches_expr attribute
    of the tree tag. The objectValues function of a folder returns all
    objects contained by that folder.

    You can however, specify a list of object metatypes that it should
    return. objectValues(['DTML Document']) will only return all DTML
    Document objects in a Folder. Other metatypes you could select on
    are: Folder, DTML Method, File, Image, Mail Host, User Folder and
    Session.  This is not a complete list, as Products can and will
    define their own metatypes. If you want to show more types, just
    add them to the list, like objValues(['Image', 'File']).
    
    Example of a Folder tree (with links to them)::

        <!--#tree branches_expr="objectValues(['Folder'])"-->
            <A HREF="<!--#var URL1-->/<!--#var id-->">
            <!--#var title_or_id-->
            </A>
        <!--#/tree-->

* How can I collapse or expand a tree using a URL?

    The tree tag will show a tree fully expanded when the 'expand_all'
    variable is present in its namespace. So when a URL, showing a
    tree, is called with ?expand_all=1, the tree tag will expand all
    it's branches.  Collapsing can be achieved with collapse_all.

    The following example shows a tree with collapse and expand
'buttons'::

        <A HREF="<!--#var URL0-->?expand_all=1">
          Expand all</A>|
        <A HREF="<!--#var URL0-->?collapse_all=1">
          Collapse all</A>

        <!--#tree--><!--#var id--><!--#/tree-->

* How can I limit a tree to showing only *one* branch at a time?

    Use the 'single' attribute for your tree, like in::

        <!--#tree single--><!--#var id--><!--#/tree-->

* What is the difference between a DTML Method and a DTML Document?

    A DTML Method is what used to be just a Document in pre 1.10
    releases. DTML Methods are not objects, they are methods. If you
    have a folder called 'foo', and it contained a DTML Method called
    'bar', then 'bar' is a method of 'foo'. 'foo' doesn't contain the
    object 'bar', it has the method 'bar' bound to it. What this means
    is that from 'bar''s point of view, 'self' is a Folder object, and
    any properties it sees are properties of 'foo', not itself.

    DTML Documents are Zope Objects. Their idea of 'self' is
    themselves.  They are contained in folders, but are not methods
    bound to that folder, they are instances of
    'DTMLDocument.DTMLDocument'. They can manage their own Properties
    (because they inherit 'PropertyManager.PropertyManager').

    Both DTML Documents and DTML Methods can hold DTML and content.
    The difference is subtle. DTML Methods would be used when the
    answer to the question "Am I showing some other objects content
    through me?" is Yes. DTML Documents should be used when the answer
    to the question "Am I the content I want to display?" is Yes. 

    DTML Methods have the advantage that they don't have any
    properties, and their perspective of aquisition is from their
    containing folders point of view. DTML Documents have properties
    which may interfere with aquisition you'd want to do, and
    aquisition is from their own point of view, which may not be what
    you want.

* How can I show all form data/cookies/REQUEST vars without knowing
their
names?

    By using the #in tag, you can easily all show all data in any
    dictionary object, like 'REQUEST.form', 'REQUEST.cookies' and even
    'REQUEST' itself. Just call the 'items()' method of the
    dictionary, and the #in tag will provide a 'sequence-key' and
    'sequence-item' variable for every item in the dictionary.

    Show showing all form data can be done like this::

        <!--#in "REQUEST.form.items()" sort-->
          <!--#var sequence-key-->:<!--#var sequence-item--><BR>
        <!--#/in-->

    Use 'REQUEST.cookies.items()' for all your cookies, and
    'REQUEST.items()' for all 'REQUEST' variables, including CGI
    Environment variables.
    
    If you don't mind the format, you could use '<PRE><!--#var
    REQUEST--></PRE>' as a shortcut.

* What is a Principia Draft?

    A Principia Draft is a special copy of any Zope object that is
    invisible to visitors of your site. You can make changes to this
    copy, and grant access to outsiders to view your changes (or work
    along with you). When all changes are done, you can approve all
    the changes, or discard them. Approving will make the changes
    permanent and visible to your audience. However, currently Drafts
    can appear to be broken.

    To add a draft, choose Principia Draft from the popup menu and
    click 'Add'. Next, you will have to supply an ID for the Draft,
    and specify on what base object you are going to work. Clicking
    'Add' in this screen will create the Draft for you. Next, you will
    have to specify who will have access to the Draft.

    Here the problem starts, because of the way Drafts are
    managed. First, a Draft doesn't acquire any users from its parent,
    so you will have to add anyone who has to have access explicitly,
    even if they have already been access to a parent Folder. But the
    biggest problem is that you can't reach the UserFolder and
    Approval screens via the management screens. This will make a
    Draft a bit harder to use, but it still is workable.

    This second problem is caused by convention changes in the Folder
    object (or the ObjectManager class really, used by Folder). I
    think that Folder objects *used* to call 'title_and_id' on a
    object when displaying it in it's management screen, but the
    current release of Zope constructs the id and title of an object
    by using its id and title separately.  Principia Drafts made use
    of the call to 'title_and_id' to insert links to its UserFolder
    and Approval management screens. As this now doesn't happen
    anymore, you will have to type in the URLs to the screens
    yourself.

    You can reach the screens calling the Draft object's
    'users__draft__.manage_main' and 'manage_approve__draft__'
    methods. The URLS are::

        http://yoursever.com/Zope/Draft/users__draft__/manage_main

    and::

        http://yoursever.com/Zope/Draft/manage_approve__draft__

    So, the next step is typing in the URL to the Draft's UserFolder
    management screen, and adding all users that should have access to
    the Draft. These users can now edit and view all changes made to
    this Draft.

    When done, you go to the 'manage_approve__draft__' management
    screen, and approve, or discard the changes.

* How does my Folder Product load default documents?

    Create a list of tuples containing filenames (without '.dtml') and
    title pairs::

        self.defaultDocs = [
            ('index', 'NotMail'),
            ('address', 'Address Book'),
            ('attach', 'Attach a File'),
            ('composer', 'Compose a Message'),
            ('contact', 'Contact Developers'),
            ('search', 'Search Your Mailboxes'),
            ('results', 'Your Search Results'),
            ('folder', 'Mailbox'),
            ('message', 'Message'),
            ('help', 'Help'),
            ('lookup', 'Lookup Users'),
            ('standard_footer', 'Standard HTML Footer'),
            ('standard_header', 'Standard HTML Header'),
            ('noto', 'Message must have at least one recipient.'),
            ('reminders', 'Your Reminders'),
            ('save', 'Save Message'),
            ('logout', 'You have been logged out'),
            ('GPL', 'The GNU General Public License'),
            ('sentmail', 'Mail was sent')]

        # Then iterate over them and create each one

        for id,title in self.defaultDocs:
            try:
                self.defaultDocFile(id, title, id)
            except:
                pass

        # defaultDocFile is a handy little function:

        def defaultDocFile(self, id, title, file):
            f=open('%s/Products/NotMail/%s.dtml'
                   % (SOFTWARE_HOME, file))
            file=f.read()
            f.close()
            self.manage_addDocument(id, title, file)

    When you are debugging your DTML, it's a pain to keep deleting and
    creating new instances of your object in order to load the new
    dtml files off of the disk. This function comes in handy::

        def refresh_docs(self, REQUEST):
            """ refresh documents from disk (for debug purposes) """
            
            for id,title in self.defaultDocs:
                try:
                    self._delObject(id)
                except:
                    pass
                try:
                    self.defaultDocFile(id, title, id)
                except:
                    pass
            return self.manage_main(self, REQUEST)

    Then, assuming your object has an attribute 'debug' you can define
    some DTML like so in your manage_main screen::

        <!--#if debug-->
        <p><a href="refresh_docs">Refresh Documents from disk</a></p>
        <!--#/if debug-->

* How do I add management tabs to my folder sub-class?
   
   If you subclass 'OFS.Folder.Folder' to build a folderish object,
   you may want to keep around the old Folder management tabs, but add
   some of your own as well. This can be done by mucking with the
   Folder class 'manage_options' attribute. One problem is that you
   might want your own custom 'manage_main' but the FolderClass uses
   'manage_main' for displaying the contents of the folder. Here is
   what I did for my EMarket product.
   
   By examining Folder's manage_options::
   
       for option in Folder.manage_options:        
           print option 

   We get the following output::

       {'label': 'Contents', 'target': 'manage_main', 'action':
'manage_main'}
       {'label': 'Properties', 'target': 'manage_main', 'action':
'manage_propertiesForm'}
       {'label': 'Import/Export', 'target': 'manage_main', 'action':
'manage_importExportForm'}
       {'label': 'Security', 'target': 'manage_main', 'action':
'manage_access'}
       {'label': 'Undo', 'target': 'manage_main', 'action':
'manage_UndoForm'}
       {'label': 'Find', 'target': 'manage_main', 'action':
'manage_findFrame'}
   
   Notice that the "Contents" tab calls Folder's manage_main attribute.
Just
   rename that in your sub-class with something like::
   
       manage_contents=OFS.Folder.Folder.manage_main
   
   and assign that to a different tab. Here is the beginning of the
MarketItem
   class from the EMarket product::
   
       class MarketItem(OFS.Folder.Folder):
           """A MarketItem """
   
           # Specify a name for the item type:
           meta_type='MarketItem'
   
           # Specify a relative URL for the icon used to display icons:
           icon='misc_/EMarket/marketItem'
           
           # rename Folder's manage_main to manage_contents
           manage_contents=OFS.Folder.Folder.manage_main
  
           manage_main=HTMLFile('marketItemEdit', globals())
           manage_image=HTMLFile('marketItemImage', globals())
   
           # Specify definitions for tabs:
           manage_options=[
               {'label':'Attributes', 'action':'manage_main'},
               {'label':'ImageUpload','action':'manage_image'},
               {'label':'View',       'action':''},
               ]
   
           # add in the options from the Folder class.... change
           # the 'action' for Contents to 'manage_contents' 
           for item in OFS.Folder.Folder.manage_options:
               if item['label'] == 'Contents':
                   # be sure to use a *copy*
                   manage_options.append(item.copy())
                   manage_options[-1]['action'] = 'manage_contents'
               else:
                   manage_options.append(item)

Message-ID: <14051.53317.19816.135841@cuckoo.EMBL-Heidelberg.DE>

Hi Zopists,


using StructuredText 
 ($Id: StructuredText.py,v 1.11 1999/02/08 18:13:12 klm Exp $)
for content generation, I find that I can't include tilde (~) characters in
hyperlinks, i.e. a  string like 

	"brabbel":http://www.embl-heidelberg.de/~ehrlich.

is not mapped to 
	
	<p><a href="http://www.embl-heidelberg.de/~ehrlich">brabbel</a>.</p>

but output as literal 

	<p>"brabbel":http://www.embl-heidelberg.de/~ehrlich</p>.
				
I tried to fix StructuredText,StructuredText.__init__ by inserting '~' into
the gsub statements. No success whatsoever...

As I couldn't find this entry neither in the Collector nor in the archive,
I wonder whether somebody has a patch sitting somewhere?

Cheers,
	Lutz

I just ran into this error. When I did a SELECT * on joined tables it would
give the error but if I named the fields I needed it worked. I played with
it a little and got the error again when I named a field that ended in _num
in the SELECT. I have four such INT fields that I don't need, they are used
by the JOIN, and have _n counterparts in the JOINed tables (see SQL below).
As you can see my SELECT list is long and it would have been nice to just
use a * since I need almost all the fields.

Everything works fine in MySQL client but from Zope I can produce that error.

Maybe there is some conflict with the *_num names. What are your field names?

I was able to find a work around.  The problem was the handling of
the TIMESTAMP datatype by the MySQLmodule.  It doesn't know how to handle
a long timestamp unfortunately, so you'll want to retrieve it as a UNIX
timestamp or as a formatted date using one of MySQL's many date functions.

The other thing is that I doubt it handles double long integers since
AFAIK Python doesn't handle these without an extension module.

If your query is returning any of these you'll most likely get this
response from Zope...

   It sure does:

    Spiffy, eh?  I'm pretty sure it's arbritrary-precision, which means you can
make numbers as large as you have memory for.  Or is this not what you
mean?

Hey, I'm glad you proved me wrong :)

It looks like there is a limitation in the MySQLmodule when handling
MySQL's LONGLONG datatypes that could probably be corrected.

I may take a look at this later, but I am thinking I may just store UNIX
timestamps in my database since this is more portable across databases
anyways.

But anyway, this may be a FAQ item as I'm sure other people may run into
it.

Hi All,

I fetched FAQ tool from "http://www.zope.org/WebReview/" but the 
archive contain only :

* __init__.py

*version.txt

*Product.dat


No, FAQ.py file. Strange no. Thus, this is maybe why I cant view 
Faq in the list of objet in Zope!!

Message-ID: <v04003a10b309c53d7c44@[192.168.1.190]>

Here is a strange one -- I am getting an L on the end of integer numbers
from MySQL. (They are INT not BIGINT!) It didn't happen in 1.9, and it
doesn't happen with methods that I created in 1.9 and moved to 1.10.2 (I
think).

In <!--#var--> I have to use fmt='%d' to get rid of it.

I also had a problem when I tried to use one in a redirect:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(num))"-->
produces:
http://server/dir/file_html?num=53L
which causes an error.

I got around that by adding an int function:

<!--#call "RESPONSE.redirect('file_html?num='+_.str(_.int(num)))"-->


Has anybody else experienced this problem? Having to add all this extra
code is driving me crazy!

While this may seem strange, this is in fact the normal contents of a
Product distribution file for a "levered product". When you build a product
through the web inside the control panel, these are the normal files Zope
creates inside the product distribution.

>Thus, this is maybe why I cant view 
>Faq in the list of objet in Zope!!

Unfortunately this is not the case. The reason you can't use the FAQ is
that there is a bug in Zope which keeps some people from being able to use
levered distributions. As discussed on the list, it appears to be related
to zlib compression.

We are aware of the problem and are working to solve it.

Thanks for your patience.

-Amos

P.S. If you're curious about a bug, you can try searching the Collector.

http://www.zope.org/Collector

In this case a search under "lever" or "faq" would turn up the existing bug
report for this problem.

When I try to install binary distribution of zope (on Linux), I run the

bash: ./python: No such file or firectory

even though python binary is there, with correct rights.
Does it mean that the binary lacks some libraries? If so, can I find

No real issues, just d/l the source release and try compiling Zope.  I'd
recommend having Python 1.5.1.  To build the source release to use the
built in simple web server, try:

'/usr/local/bin/python1.5.1 wo_pcgi.py'

to use with Apache (Note, d/l Zap and look at it's .conf file)

'/usr/local/bin/python1.5.1 w_pcgi.py'

Change the command line to reflect your python binary.

Check out, I think, INSTALL.txt in the doc directory.  All the C is
ANSI, and python is python (grin) so you shouldn't have a problem.

Hi Guys:

I think I've nailed the problem that was keeping people from using the FAQ
Tool and levered products in general under windows.

I'd love some confirmation that this does or does not solve people's problems.

The fix is to open the product.dat file in 'rb' mode. To do this, change
line 420 of lib/python/App/Product.py to:

        f=CompressedInputFile(open(home+'/product.dat','rb'),name+' shshsh')

Again, let me know if this doesn't work for you.

-Amos

P.S. Here's a little FAQ to tide you over until you're happily building
your own ;-)

Q. What's the FAQ Tool any way?
A.  Find out for yourself at: http://www.zope.org/WebReview/

Q. What's a levered product?
A. A Product created through the web by building it inside the Control
Panel. See the Zope Manager's Guide for more information.

This fix works for me (lline 407 in my Product.py) 

HOWEVER ... you must delete the FAQ product from the control panel, 
then restart ZServer for this fix to take effect. Apparently the old FAQ in 
bobo inhibits re-reading of the product.dat file.

There's a bug in the code, something I noticed when I was playing 
with the examples too. this is the fixed version:

001 <!--#in "['Document','Folder']"-->
002 <!--#with subFolder-->
003 <!--#if "objectValues(_['sequence-item'])"-->
004    <H3>Objects of type <!--#var sequence-item--></H3>
005   <TABLE BORDER=1>
006   <TH>Id</TH><TH>Title</TH>
007      <!--#in "objectValues(_['sequence-item'])"-->
008        <TR><TD><!--#var id--></TD>
009        <TD><!--#var title--></TD></TR>
010      <!--#/in-->
011   </TABLE>
012 <!--#/if-->
013 <!--#/with-->
014 <!--#/in-->

About the bug and the fix:
the bug was due to the statement <!--#if
"objectValues(_['sequence-item'])"-->
looping over the current folder, not the subFolder which it should be.
By moving the "with" statement to enclose it (see line 002), the
statement <!--#if "objectValues(... now loops over the objects inside
the folder named "subFolder".

I don't know who is maintaining the ZopeDemos product (or if it's
being maintained at all), 
but I hope he/she takes note of this and posts an update. 

Hope this helps.

Butch Landingin
butchland@yahoo.com

PS. I'm playing around with the Confera product (making it more
slashdot-like) but I know it's
not "officially supported" by Zope/DC -- so who's maintaining it? I
have some detailed questions about the code (but I don't know if it's
off-topic for Zope/Zope-dev).

Zopistas

The new version of the FAQ has been uploaded at:
http://www.gaaros.com:9673/FAQ

The format has been changed after Martijn Pieters suggestions. It now
supports structured-text as the default format. Actually it was pretty
easy to upload Martijn Faassen's FAQ.

The e-mail uploading option has been dropped. If you want to submit a
FAQ entry you can do it over the web. Also the XML DTD has been changed
slightly. A typical entry would be:

<entry>
<section>DTML Scripting</section>
<question>How to you become a hermit?</question>
<author>Pavlos</author>
<email>pavlos@gaaros.com</email>
<answer>
Simple:
	
  - Install Python

  - Install Zope
</answer>
</entry>

Only the section and question fields are required. Everything else is
optional. You can view the DTD on the site. Suggestions will be
appreciated.

Is the only advantage of using the first (sqltest) the type checking? I
can't find any other obvious advantages.

Butch,
Thanks for the reply - but this doesn't work completely either. I can 
add folders and delete them and the changes made show up in the 
listing, but adding documents (both documents and methods) has no 
effect. If I delete the *original* documents created by the 
installation, they show up as being gone, but even a copy-paste of 
the original documents doesn't get any new documents/methods etc. to 
show up.

Am I doing a dumb newbie thing here? (I *do* have a folder called 
'subFolder' btw).

many thanks
tone

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <19990309084120.83ca0fd9.in@mediamail.telinet.com>

Hi all,

I have been using python for years, and zope for a few months now (lovely),
ZServer for weeks, but Windows NT? Not long enough to understand the
differences between services and ordinary process (give me a break, I am
heavily from a Un*x background) :-).

I know when I installed the binary version of Zope on the windows machine
here it gave me a service in the services list which I can activate on
startup. However, I am betting that this runs the ZopeHTTPServer, not the
ZServer which I got as a separate download. I have everything working just
lovely with the ZServer now, but it needs to be run as an NT service (and
respond to start and stop signals, etc) at which point I freely admit my
own inadequacies in this area.

Now my question. How can I do what I need to do. Is it simply a case of
redirecting a python 'shell' file used by the service to the start.py in
the ZServer module, or is there more to it? If it is this simple, which
python 'shell' file do I use? If it is not this simple, can someone send me
basic instructions on how to do it (why is NT like this - give me an
rc.local file any day - I know where I stand with that stuff).

Thanks in advance.

Dick

Zope-dev is the place to ask specific questions about Zope's API and
Zope Product Authoring.  Go ahead and ask your questions, the unsuported
just means we can't make any guarantees or commit company resources to
it, but if your question happens to use Confera as it's basis all the
better.  Someone out there might have the answer.

Hi All,

The DTML Example folder has been updated. I've incorporated the fix below,
but the reason that new documents were not showing up is that the page was
looking for the wrong 'meta_type' for objects in the subfolder. Up till the
last release, documents had a meta_type attribute of 'Document', but now
documents either have 'DTML Document' or 'DTML Method' as their meta_type.

Tony's problem was that Zope was correctly respecting the meta_type of the
'old' Document objects included with the demo, but any new documents added
afresh were being created with the 'DTML Document' or 'DTML Method'
meta-types, which were falling through the objectValues 'sieve'.

Here's the new version...

Cheers,

Andy.

<!--#in "['Document','Folder', 'DTML Document', 'DTML Method']"-->

I haven't played with it too much but I think that Zope handles undefined
variables properly if you do the sqltest.

ie.

where <!--#sqltest name column=column_name type=column_type-->
and <!--#sqltest name2 column=column_name2 type=column_type-->

will work if name2 is not defined.

It also handles the quoting and SQL syntax (such as doubling single quotes).

My guess is that you created your original database in Zope-1.9 and then
moved everything into Zope-1.10. If that is the case then you need to
replace
<!--# in "objectValues(['Document'])"--> with
<!--# in "objectValues(['Document','DTML Document','DTML Method'])"-->
or something to that effect.

Not quite.  ZopeHTTPServer is a console app just like ZServer.  The
service is a PCGI-like thing that runs Zope as a service, listening for
named pipe connections from something that is run as a CGI by the web
server.

ZServer is still at alpha 2 so it's premature to focus on things like
how it is packaged.  I *think* we have all the issues figured out and
the next release, perhaps this month, will be a beta1.  Until we get
into beta, we'll have to hope that someone in the community packages it
up as a service.

One issue off the top of my head is integration with the NT Event Log.

Absolutely...  we ran into some situations where the SQL was so dynamic
potential security problems arose.  sqltest and sqlvar are designed to
reduce that exposure.

Additionally, we've found a very common rhythm where a search UI might
expose all of a large percentage of the available data elements in the
RDBMS.  Using sqltest lets the user not specify one or more parameters
without a lot of messy <!--#if --><!--#/if --> stuff in the SQL Method.

I'll correct myself here. I was thinking of the <!--#sqlgroup ...--> tag. I
don't know what <!--#sqltest ...--> does that <!--#sqlvar name--> or
<!--#var name fmt=sql--> won't do...

I meant to bring this up in my earlier post -- this tag too, is used to
simplify what could be a terribly complicated SQL Method given an
indeterminate number and list of search criteria.

With this tag you can permit an arbitrary arguments to be supplied
connected with your predetermined ANDs and ORs

This one tag has, in the past, reduced may SQL Methods into one --
natural maintenance savings.

A _very very_ nice feature of #sqltest is the 'multiple' feature.  For
example:

SELECT * FROM inbox
WHERE <!--#sqltest doc_status type=string multiple-->

If doc_status is passed in as a single value, like "foo", the SQL statement
will be rendered as::

SELECT * FROM inbox
WHERE doc_status='foo'

BUT!!! (this is where it gets good), if doc_status is passed in as a
list/sequence, like ["foo", "bar", "drop", "ship"], it will be rendered
as::

SELECT * FROM inbox
WHERE doc_status in ('foo','bar,'drop','ship')

This is an _extremely_ handy feature of #sqltest.  Prior to #sqltest, doing
the above might be like:

SELECT * FROM inbox
WHERE doc_status in (
 <!--#in doc_status-->
 '<!--#var sequence-item fmt=sql-->'
 <!--#else sequence-end-->,<!--#/else-->
 <!--#/in-->)

(#else used to be used where #unless is used today).  The above code also
always required doc_status to be passed in as a sequence.  #sqltest is
smart enough (I believe - i've never been bitten by this) to detect the
difference between strings and lists.

I've used #sqltest with multiple many times with Acquisition where a folder
property would define part of a SQL statement.  That property in some cases
would be a single value, in other places it would be a tokens or lines
property.

So, in otherwords, you get the type checking, the multiple, the optional,
etc... with #sqltest that you don't get otherwise.  About the only problem
is that #sqltest currently doesn't do not-equals or "not in (...)".

Subject: [Zope] tree doesn't work 4me linux amd win32
Message-ID: <199903091705.RAA07667@teak.shu.ac.uk>

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?

Andy
btw: Zope looks really good to me (when I can get over these glitches).

I found that this problem came up when I used MEDIUMINT in MySQL. I changed
my database to INT and it worked fine.

I bet your using a DTML Document.  Try using a DTML Method.  The reason
why the tree tag renders nothing for the DTML Document is because DTML
Documents are not containers of other objects, they are objects to hold
DTML content.  DTML Methods are (and this is the suble thing) *methods*
of the Folder object that contains them.  They are not 'objects' in the
same sense of the term used for DTML Documents (I can hear Jim saying
now "*everything's* an object").  Because Folder objects *are*
containers, the #tree tag used in a Folder's DTML Method will render the
contents of that Folder.  Hadar's example is a little outdated, it is
based on 1.9, in which DTML Documents didn't exist, and all Documents
were DTML methods.

Subject: [Zope] ZServer as a windows NT service?
Message-ID: <006501be6a52$b0bbe900$fa01a8c0@rogue>

I currently have ZServer running as a service on two machines using the
srvany.exe tool from the NT resource kit or from MSDN.  Essentially srvany
is the actual service and then you tell it via registry settings what other
program you want to run.  It works good enough for me for the time being.

The only problem is that the service stop message does a hard kill on the
ZServer process so any last second updates to the Zope DB might be
fragmented if it wasn't finished writing, but with the way the DB works at
least the DB will still be usable.

I am out of the office right now so I can't provide step by step
instructions right now.  There is a .doc file that comes with srvany.exe
that I followed.  I specified that Python was the executeable to be run by
srvany, the ZServer directory is to be the CWD, and that the command-line
should be start.py.  Worked first try.

Of course the right thing to do would be to integrate native service
capabilities into ZServer itself via the win32api packages.  That way
ZServer could shhutdown gracefully and could send meaningful things to the
event log.  But srvany is good enough for alpha level, non-production
servers.  And I havn't had any problems to speak of dealing with running it
as a service.

Message-ID: <3.0.5.32.19990309103419.00a35920@email.byu.edu>

I just installed the updated version of PostgreSQL 6.4.2 on Linux 2.2.2.  I
was able to compile and add the ZPyGreSQL Product to my Zope installation.
I want to create a Database connection.  When I go to create a new one, it
asks for the Id, Title, and Database Connection String.  What do I put into
the Database Connection String?  I tried the database I want to use, but it
gives

Invalid connection String: baseball

Is it a rights issue with PostgreSQL or something else?  What is it
expecting the database connection string field anyway?  Thanks for your help!

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC4A@peter.sths.org>

I have a nifty system whereby each individual I add to a database
automatically gets a personal directory and password. One of my users
has come to me with a problem. He can add images to his directory, but
cannot subsequently edit the image (i.e. open the image's manage screen)
as it complains about lack of permissions. The security role he has
contains all the image related options I see. He can delete it, btw.
This is not an immediate issue, but I do wonder why the permissions
don't seem to be working in a sensible manner. Why should he be able to
add images, but not manage them? Are there extra 'image manage'
permissions? If so, where do I find them?

Subject: [Zope] FAQ 0.2 - About this FAQ
Message-ID: <36E56988.CEF76199@pop.vet.uu.nl>

Zope FAQ 0.2 - About this FAQ and the Zope Documention Project

* What is this FAQ?

    This FAQ is a project of the Zope Documentation Project, and aims
    to answer any (or at least lost) questions you might have about
    Zope and how to use it.

* What is the Zope Documentation Project?

    The Zope Documentation Project (ZDP) is a community project of
    Zope users that aims to create documentation for Zope. The first
    goal of the ZDP is the creation and maintenance of an extensive
    Zope FAQ, later on other documentation will follow.

    We welcome everybody to contribute; for instance by sending in
    questions and answers for the FAQ.

* Where is the rest of this FAQ? 

    The Zope FAQ has been split into separate sections. If you are
    reading this on the ZDP mailing list, you should see the other
    documents posted as well.

    If you are reading this on zope@zope.org or zope-dev@zope.org, you
    will only see this message. The Zope FAQ is under development. It
    is probably already useful, but because I don't want to spam
    everybody you will have to look at the ZDP list to see the rest of
    the FAQ. Everyone is very welcome to join the ZDP list. 

    You can also wait until the ZDP has its web infrastructure going
    and the FAQ is published on the web. This will hopefully be very
    soon; we're working on it.

* How do I contribute?

    The Zope Documentation Project has its own mailing list
    (zdp@zope.org). You are encouraged to use this list for all ZDP
    related communications. Please do not send your messages (such as
    FAQ contributions) to Martijn Faassen (the current FAQ maintainer)
    if your message can be sent to the mailing list instead.

* How do I join the ZDP mailing list?

    You can subscribe to the ZDP mailing list by using the page::

        http://www.zope.org/mailman/listinfo/zdp

    Thanks in advance for your contributions!

* Are there other Zope-related FAQs?

    Yes, there is the "Zope Questions and Answers" at::

        http://www.zope.org/Information/QA/

    This is maintained by Digital Creations; currently it is the best
    place to look if you are brand new to Zope.

    That said, Paul Everitt of Digital Creations has kindly
    contributed the Zope Questions and Answers to the ZDP (or vice
    versa; the ZDP is contributing to the Q&A). The ZDP plans to merge
    the two FAQs shortly.

* What is Structured Text and what does it have to do with this FAQ?

    The FAQ is (currently) written in Structured Text, so you may very
    well reading the FAQ in Structured Text format (the double colons
    and the indented paragraph structure give it away). If you are
    just reading this FAQ you shouldn't worry about it. 

    If you plan to contribute to the ZDP we'd prefer it if your
    contributions were written in Structured Text, however. For more
    information see the Structured Text section of this FAQ.

* What are these FIXME comments I see scattered through the FAQ?

    If you are reading the ZDP mailing list or its archives, then it
    is the FAQ's editor (or possibly a contributor) who is not
    entirely sure about some details on Zope, and is asking people on
    the list to help figure it out.

    If you are reading this FAQ somewhere else, then oops, they don't
    belong there. Please send a message to the zdp@zope.org list
    telling us about it, and thanks!

* What other sections does this FAQ have?

  We currently have sections on:
  
      o DTML
 
      o Zope Administration

      o Structured Text
 
      o External Methods
   
      o Builtin Products

      o Product Development

"The CD Index project (this is a temporary name -- we should find a better

Make sure the user's role has the "Change Images and Files"

I have put the lines (with modification reflecting my placement of

Subject: [Zope] Root Folders and Names {Manager's Guide Update}
Message-ID: <02c001be6a6d$a24716e0$0201a8c0@hawkeye.bob.oc>

* How do I "name"  the *blank* root folder?

This is the same folder that is named "Plutonia" in 
the Zope manager's guide. 

Maybe the root folder has no name so
that if I go to  http://www.bob.com/  the 
"Folder at /     " will present index_html 
to requesting browsers.

If I did name it "plutonia" would it be accessible
both as
http://www.bob.com/   and as
http://www.bob.com/plutonia  ?

So maybe I don't need to "name" this root
folder.  If so, then the Zope manager's guide needs
to be clearer. In the fourth paragraph on page 12 
it says:

"...presuming that your ZOPE is installed at 
http://your.place.com/Objects and it's management
screen is at http://your.place.com/Objects/manage"

This does not follow through the document.
There is no folder named "Objects"

Maybe the document should say:

http://plutonia.com/ and it's management
screen is at http://plutonia.com/manage"

And to manage one of the three departments
used in the examples, say for 
example "News" then:
http://plutonia.com/news/manage"

Other notes on this issue: 
Timothy J. Grant asked:
"...My problem is that my Root folder in Zope has 
no name, and it appears that FSIMPORT requires 
a folder name for it to work."


No response was found to this post on 
the ZOPE list.

I've gotten Zope up and running on my IIS/NT server. Right now I can access it 
through www.myserver.com/cgi-bin/zope.exe. Is there any tricky way to get it to 
run as www.myserver.com/zope? including www.myserver.com/zope/folder/object?

Can you do that with Apache on NT?

I would use ZServer but I need to also be able to run Perl CGI scripts.

Right now you can't. And you don't need to. The "name" of the root folder
is simply the SCRIPT_NAME your webserver uses to access Zope. By default in
ZServer and ZopeHTTPServer this is an empty string, since they both
normally server one published module, though they both can server multiple
published modules.

So, you can give your root folder a title, but you can't use Zope to change
how your web server calls Zope. Do this with your webserver. In the case of
ZServer, check out the zope_handler.py, it has options to set the
SCRIPT_NAME. ZopeHTTPServer also has options to set the SCRIPT_NAME with
command line arguments.

Right.

Perhaps the docs should be updated. The manager's guide probably assumes
that you're using PCGI, but it shouldn't make this assumption.

Hope this helps.

Message-ID: <Pine.LNX.3.96.990309162504.454A-100000@taos.kavi.com>

Is this behaviour a bug?

I have all my ZSQL methods collected together in a folder. If I call these
from a sibling folder[1] without any arguments, ie.

<!--#in "sql.company"-->

I get the below error, if I call them with specific arguments, ie.

<!--#in "sql.company(comp_id=_['comp_id'])"-->

I get no errors. (comp_id was in REQUEST in both cases).

[1] by sibling folder I mean something like the following arrangement...

/sql/company  		(where the sql method is stored)
/lists/company_list 	(where the call is made)

Here's the error:

<!--
 Error type:

Looking into it, line 332 in Aqueduct.py is a simple key lookup...

    def __getitem__(self, key): return self._data[key]

It would seem that an argument is getting passed in by default when the
sql in put in a parent's subfolder.

Message-ID: <Pine.LNX.3.95.990309165933.6532A-100000@animal.blarg.net>

I have been playing around with Zope/ZPublisher/DocumentTemplate and have
been extremely pleased with the ease of development, as well as the power
of the Python language.

Sometimes I have found myself wanting to save the results of an expression
in my DTML code, for use later in the same page (or even an embedded DTML
object).  The only thing I have used that is similar to DTML is
ColdFusion, which has a CFSET tag, ie: <cfset myvar = "test"> or
<cfset total = subtotal * tax>

In reading the docs, it looked like I might be able to do something along
the lines of <!--#call "REQUEST.set('var', 'value')--> but this didn't
seem to work, and it's not very elegant either.

Am I missing something? None of the howtos or tutorials seem to cover
this.  A <!--#set newvar=oldvar--> / <!--#set var="expr"--> would be
really spiffy. =)

Please make sure you CC me if you respond to this message, as I had to
unsubscribe due to the overwhelming amount of traffic.

Thanks!

Subject: [Zope] tree doesn't work 4me linux amd win32

I'm a zope newbie.

I just installed on a windows 95 box and on a linux 2.0.something
but I can't get anything with tree working (other stuff seems ok).

Hadars' second sample app doesn't work for me (the tree part
produces no output).

Even the minimal

<!--#tree-->
<!--#/tree-->

doesn't produce output (tried this with the second Habar example after
creating the "sub-folders").

I get the same behaviour on windows as linux.

I must be doing something wrong.  Clues please ?



I had the same problem, but only with Zope 1.10.2.  I noticed that DTML
documents (the default to be created) won't work with the tree tag.  If you
create a DTML Method (like the old DTML from Zope 1.9) then they work as
expected.  I don't have a clue as to why this works like this.  Maybe its
the proerties of the DTML Documents that are acting folderish and tree
doesn't know what to do?

Hope that helps,

Message-ID: <4.1.19990309224955.009de8f0@10.0.0.1>

We have been unable to access properties of the new DTML Document objects
in the same way we used to access properties of Folders. 

I don't know whether we are doing something wrong or we found an
inconsistency in the new 1.10 Zope API.

Here is a very simplified test case illustrating the issue.

I have a folder with these contents:

folder1 [Folder]
- broken_html [DTML Document]
- index_html [DTML Document]
- sub-document (The Grand Sub-Document) [DTML Document]
- sub-folder (The Grand Sub-Folder) [Folder]

The source of index_html (which works) is:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-folder'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-folder'].author"--></p>
<!--#var standard_html_footer-->

This works as expected. The properties title and author of the sub-folder
are retrieved.

The source of broken_html is exactly the same, except for the sub-document
reference:

<!--#var standard_html_header-->
<h2><!--#var title_or_id--></h2>
<p>Title of sub-item: <!--#var expr="_['sub-document'].title"--></p>
<p>Author of sub-item: <!--#var expr="_['sub-document'].author"--></p>
<!--#var standard_html_footer-->

Viewing this document-method I get a "Zope Unavailable" message with this
traceback:

<!--
 Error type:  
 Error value: 'string' object has no attribute 'title'
 -->
</BODY></HTML>
<!--

So, how do I access properties of sub-documents from a sub-document in the

One way is to use DTML Methods instead of DTML Documents.

Nope, ZHS (for short) is derived from the example CGIHTTPServer.py that
ships with Python---it's heavily modified though.  ZServer is what is
derived from Medusa and is currently in alpha (though pretty stable for
me).

As for SSL, not currently, and I'm not sure what's going to happen with
this.  You can use Apache+SSL right now for this.  I've had some
thoughts about it, but I'm not sure how SSL will impact an async-socket
based system...  the setup of new SSL connections is kind of heavy.

I am using:
Red Hat 5.2
Zope 1.10.2

- I created a username of "zope_u" and a group "zope"

- I did run the installation script with a command line like:
        ./install -sAdmin:MyPassword -u zope_u -g zope

- I created the Feedback and SendFeedback forms as per the manuals.

- I added the user "zope_u" to the mail group.

- I modified user zope_u's .bash_profile file to include the path to
sendmail in /usr/sbin

- If I log-in to the Linux server as zope_u, I _am_ able to call sendmail
and to send mail outside of the server.

Anything else I missed, folks?

Regards.

I understand the difference between DTML Methods and DTML Documents. 

The very reason I chose to do it with DTML Documents was to be able to
store some special fields, such as 'author' in my example, along with the
document. I cannot do that with DTML Methods, as they do not have properties.

In Zope 1.0.9 I used folders but I was running into problems with relative
links. It seemed natural to switch from my previous folders to the new DTML
Documents.

I still do not know to reference the properties of a DTML Document 'A' from
within a document or method 'B' in located in the same folder as 'A'.

Thanks for any help.

You are right. I was using folders too for the same reason.

You can use the PARENTS variable.

so if you have a folder which contains two DTML Documents A and B then
you can access B's properties from A by:
<!--# var "PARENTS[0].B.name"-->
PARENTS[1] will return the folder or containing object one level up and 
PARENTS[-1] will return the top most Folder.

Thanks for your help, Pavlos. I found another way. Instead of writing:

<!--#var expr="_['sub-document'].author"-->

I wrote this, and it worked fine:

<!--#var expr="_.getitem('sub-document').author"-->

I found a way, but I don't understand why the first syntax worked fine with
Folders and fails with DTML Documents. If anyone would like to clarify the
semantic difference between _['sub-document'] and
_.getitem('sub-document'), I would be even happier.

By the way, Pavlo's site http://www.gaaros.com:9673/ is useful!

The answer is in both the ZDP's FAQ and the DTML Manager's Guide. 

_['foo'] "renders" foo according to DTML rules. This process mostly
consists of calling DTML and other callable objects.

_.getitem('foo') simply returns foo as found in the DTML namespace.

The reason you were having problems is that _['sub-document'] renders the
document to a string. Naturally strings don't have properties. Hence the
error you got from Zope, "'string' object has no attribute 'title'".

Make sense?

Message-ID: <Pine.BSF.4.05.9903092345060.330-100000@guru.phone.net>

I'm trying to get zope working to study it, but keep stumbling over
the "(102) failure during connect" error - with the "No such file or
directory" addendum.

The underlying OS is FreeBSD 3.1. I want to run it on an Apache web
server (at least for now), with the server doing the
authentication. That all appears to be working properly - after all,
I'm getting errors from pcgi, now, right?

The var directory is writable by nobody. In fact, the entire source
tree is owned by nobody, which is the user that the Apache httpd is
running as. However, I get log file entries from pcgi, even after
deleting the pcgi.log file. I initially tried copying the Zope.cgi
file to cgi-bin, but noticed that some (unspecified) setting in
Zope.cgi might need to change because of that, so I added a second
scriptalias to the Apache httpd.conf pointing at the source directory,
set the protections on it, and tried to load <URL:
http://localhost/Zope-bin/Zope.cgi/manage >. No change - the log file
records the same error message.

The pcgifile.py test reports 

	error attempting: 'from cgi_module_publisher import publish_module'

This doesn't appear to exist in the distribution - and I recalled
something about that being a holdover from bobo, so I removed that
test from the script, and ran it again. The modified version runs
cleans.

Was I wrong about cgi_module_publisher? Should it be finding that? If
not, then what's the next thing to look at?

FWIW, here's the entry from httpd.conf section for Zope:

SriptAlias /Zope-bin/ "/home/mwm/external-src/Zope-1.10.2-src/"
<Directory "/home/mwm/external-src/Zope-1.10.2-src/">

	Auth_PGpwd_field	password
	Auth_PG_encrypted	off

	AuthName		"Zope"
	AuthType 		basic
	require			valid-user
</Directory>

And here's Zope.cgi:

   You don't need hostname and port part, so the connection string can be
just "baseball user_name".
   (BTW, without host:port, libpq will connect to postgres using UNIX
sockets, not TCP/IP. I think it is much better - for speed and security)

Message-ID: <199903100907.UAA01717@mbuna.arbhome.com.au>

I've got an external method that is generating a (possibly quite large) 
audio file and sending it back. Right now, I'm generating this in memory
in a big string, then returning it to zope. I'd _like_ to be able to just
have the external method send the data straight through (maybe in chunks)
without having to read it all into memory. Is this possible with zope
at all?

Because you are calling "sql.company" (in quotes), it is assumed to be an
expression, and your expression is referencing an attribute, not a method.
Try using the following: "sql.company()", or sql.company (without quotes).
Note: I didn't test either method.

MailHost doesn't use sendmail, but rather opens a socket to the specified
sendmail host and uses the SMTP protocol to send the messages. This is
somehow prohibited. It looks like there is maybe no SMTP server listening
on the specified address and port, or your machine is not allowed to
connect. You could try and do a manual telnet to the address and port from
the zope_u account and see what happens.

Make sure you also go through the motions, like HELO <hostname>, and such.

Can #sqltest handle the 'wildcard' situation in MySQL (and probably 
other DBMSs too)

select * from tbl where tbl_val like '%nib%' is a different SQL query from
select * from tbl where tbl_val = 'niblet'

my attempt...

select *
from tbl where
<!--#sqltest tbl_val type=string multiple-->

I think the first problem will be finding a publisher that streams.
PCGI buffers all I/O, perhaps FastCGI doesn't.  Even if you didn't,
sending it through Zope in chunks would avoid getting Zope's memory
footprint up there.

One way would be to have the ExternalMethod return a sequence, then do
something like:

<!--#in myExtMeth-->
  <!--#var "RESPONSE.write(sequence_item)"-->
<!--#/in-->

Of course the above might be completely wrong, but you get the drift :^)

Yes, it's a holdover from Bobo days (which some people are
still using for existing apps) but you can ignore that
particular error.

Contact me offline and we'll try to get this resolved.

Try::

   <PRE><!--#var REQUEST.form--></PRE>

or::

   <!--#in "REQUEST.form.items()"-->
      <LI><!--#var sequence-key-->: <!--#var sequence-item-->
   <!--#else-->
      No form items
   <!--#/in-->

To generate an overview of all form variables your DTML has access to.

Thanks for the suggestion Martijn but I've already tried that and it does
indeed show variables of the form 'answerbtn.x'.  But when I try to access
them using one of:

<!--#var answerbtn.x--> or
<!--#var _['answerbtn.x']--> or
<!--#var _.getitem('answerbtn.x')-->

I get a traceback error, so I am none the wiser 8^(

Thanks anyway

Any other ideas?

Read my reply to the orginal message in this thread as to why the tree
tag doesn't work as you expect in DTML Documents.

Nope.  ZopeHTTPServer is not Medusa, it is based on the HTTPServer that
comes with Python.  Medusa is it's own product, that we have integrated
parts of into ZServer (which uses the core of Medusa to drive it's
network end).

http://www.nightmare.com/medusa/

For medusa info.  http://www.zope.org/ for info on ZServer.

Once ZServer is stable (it is alpha at the moment) use of ZopeHTTPServer
will be depreciated (but not forgotten).

Subject: [Zope] New subscriber: Installing Zope
Message-ID: <199903101525.KAA25149@mail.howard.k12.md.us>

Having seen Zope recommended on Usenet last week, I decided to check it 
out, Monday I found the Webreview article in the email box.  I have been 
reading as much as I can find, but one question is always on my mind, 
when ever I find one of these wonderful, does it all systems.

Can I install it ?  Not, is it to complicated to install, but do I need 
root access to the machine to install this application.  This question 
and the answer have killed many a promising application (DB & BBS).

So, the question is, can Zope be installed in a typical Telnet account ?

The install docs mention, you have to be root user, to install some 
components, does this mean what I fear it means ? (machine admin, ie. 
super user)

Yes.  I am trying to reference a folder that is not in the same path.
And I tried your next suggestion a long time ago, with no luck. 
<!--#var candidate1.name-->, and get an error with traceback:

<!--

This doesn't work.  My paths are like, /staff/candidates/candidate1, and
staff/companies/company1/job1/submission1/MyDocument.  I am trying to
reference a property of the candidate1 folder in the MyDocument
document.

Hmm,

More on the image button saga.

It seem's that <!--#var answerbtn.x--> does indeed work, but <!--#var
_['answerbtn.x']--> doesn't, and neither does the getitem way.

Seems weird to me, any ideas?

TIA

You should be able to install a binary package as a typical user on a
UNIX machine.  If your machine already has Python 1.5.1 or higher
installed (don't they all?!?!?! :-) then you can just install the basic
source distribution of Zope and do the:

	$ python wo_pcgi.py

Thing :-)  You can then use the ZopeHTTPServer on a untrusted port (over
1000) and off you go :-)  If you want to use Apache+PCGI you probably
will need administrator support, and if yo uwant to be on a port under
1000 you'll need it.

You should be able to get a feel for it without being root.

Try Zap, the precompiled apache for Zope (Linux only).  The zap.conf
file will probably have something your not including in your apache.
also, do an 'httpd -l' and make sure you have mod_rewrite compiled
and/or dynamicly loaded in.

<!--#var "candidates.candidate1.propertyname"--> will work.

candidates is the object that is the common ancestor, and from there you
can reference objects down that path. You will have to place the expression
into quotes, however.

You can indeed install it. I had originally had a standard telnet 
sort of account on a FreeBSD machine. You can basically get a 
full-featured Zope if your web provider runs apache with mod_rewrite.
(If they don't have mod_rewrite, authentication is a little bit more
of a headache.)

The thing to beware of is that PCGI starts a long running process
and many hosting companies will not be pleased about this.

Zope 1.10.2

I have a ZSQL method for inserting data into the database.
The database connection is active.
the permissions are correct.
the method is defined roughly as:

insert into tblname (col1, col3, col4, col5) values
(col1val, "value taht is constant", col4val, col5val);

when I try and test it, Zope tells me that there
is a parse error near ';'.

I remove teh ';' and Zope tells me that 
"This was not a query."

I'm missing something, and I'm hoping it's not my 
mind . . . any help?

(oh, nad yes, the query works just fine when entered
by hand in a mysql or xmysql connection)

Subject: [Zope] title and id properties in DTML methods
Message-ID: <36E6A70C.687B26BA@pop.vet.uu.nl>

Hi everybody,

I'm probably completely confused, but if I understood it right, DTML
Methods in Zope 1.10 are the same as Documents in Zope 1.9. I may
remember wrongly, but wasn't it so that

<!--#var title_or_id-->
<!--#var title-->
<!--#var title-->

in 1.9 documents rendered the title and id of the actual document, and
not that of the containing folder? In 1.10 in DTML methods, they appear
to render the containing folder, instead. The only way I can access
title of a DTML method in 1.10, is by referring to it specifically, i.e.
<!--#var "some_method_id.title"-->.

It works as expected with DTML Documents.

Is this as it should be? Am I correct about the 1.9 behavior? If so,
then DTML Methods don't seem to be exactly equivalent to 1.9 Documents,
and this should probably be in the FAQ. :)

Regards,

Martijn

Do it without the ';'. When it says 'that was not a query' it simply
means that there was no returned results for it to display. If you check
the database, the values should have been successfully inserted.

If you're doing just a single query, you don't need the ';' (or its
equivilent).

If you're doing multiple queries, use <!--#var sql_delimiter--> to seperate
them.  The DA will seperate the queries using this.  This is equivilent to
what command line or other SQL tools often do with the ';' character.

> I remove teh ';' and Zope tells me that

Nothing is being returned is what this means (or more basically, it wasn't
a SELECT based query).

I can't use another apache just for Zope. I looked into zap.conf and
incorporated some changes into my httpd.conf. No way.

Since the log file of RewriteLog remains empty, I believe no rewriting
takes place, actually. I have about 30 virtual servers on that httpd,
maybe there lies the problem? Also this is Apache 1.3.3, do I need
Apache 1.3.4?

hi!

No. Zope works fine with Apache 1.3.3. Did you remember to set the ExecCGI
option? And did you remember to turn the RewriteEngine on?

Yes I turned rewite engine on, but maybe not in the right place. I wrote
it into global config.

I believe do not need to use ExecCGI, since I use ScriptAlias. And
Zope.cgi gets executed, I otherwise wouldn't be able to get to Zope
introductory. 

I'm desperate....

Something in an external method similar to this should do the job.

from string import split, join

def stringtounderscore(str):
	return join(split(str," "),"_");

which is then called from your page as 
<!--#var "stringtounderscore(mystring)"-->

Alternatively, if this is something you only need occasionally, you can
code it directly in DTML...

<!--#var "_.string.join(_.string.split(mystring,' '),'_'"-->

Both of these are untested, but I have tested the join/split command in
python directly:

>>> join(split("this is a test string"," "),"_")
'this_is_a_test_string'
>>>

You can use something like:

<!--# var "_.getitem('foo',0).whateverproperty"--> (Is 0 the default?)

_.getitem('foo',0) returns a reference to the object with id foo.

Thanks for a very fast reply, however it doesn't work. I'm still getting:
Error value: 'string' object has no attribute 'title'.

This is what I'm trying to do:
A DTML document (index_html) has a property art1 which has an ID for another
DTML document as value (type: string). In index_html I use: <!--#var
"_[_[('art1')]]"--> which renders the article. I can of course use
<!--#var title--> in the actual article, but I rather don't. So I'm still
banging my head in the wall after hours of trying to accomplish this. Can it
be a bug with DTML documents??

I think that DTML Methods (or Documents?) are meant. They are like
methods to the folder objects that Zope publishes. Look at:
http://localhost/Zope/foo/bar/doc as asking Zope 'okay, folder 'foo', I
want your subfolder 'bar' (this could be seen as using a method on foo
to request 'bar'), and then I want to view 'doc' (which is, let's say, a
DTML method) in bar. 'doc' in that case is a method of the bar object,
which, when called, returns HTML code (to the browser).

An *external* method is a method which comes from outside the Zope
object database (though it's loaded into it, and behaves just like a
normal internal method).

If all this talk turns out to be correct (somebody tell me or send
corrections), then I can turn this into a FAQ entry. If anybody else
feels like writing this up in a nice way for the FAQ (Oleg?) that'd even
be better. Just send your contributions to the ZDP list.

Martijn

Hi!

   That is, there are DTML Scripts and External Methods. Python code is
used in External Methods and Products, but never goes into Object Database.

I think it's true Product python code doesn't go into the Object
Database, but I'm unclear about what happens with External Method python
code. You need press the 'edit' button for an external method in Zope
each time you changed something in it and want it updated. This would
imply Python code can indeed be part of the Object database, right?

Actually not. For security reasons the code of an External method does
not reside in the Object Database but in the filesystem. When you press
the 'edit' button the code is read and evaluated and it is the evaluated
code that is stored in the Object Database. There was a thread about
whether the source code should be included in the Object Database but I
think thge Digital Creators were not convinced.

How are more than 1 value submitted from a form? How can I get those values

Help is much appreciated!

No, it forces Python to recompile the code. The code itself is NOT stored
int the object database. Only instance data is stored in the object
database, no code is. Zope classes are said to change all this, aren't
they, DC?

Pressing the 'edit' button "reloads" that particular External Method code
into the system.  It's not stored in the database at all - the External
Method object you add/edit through the Zope management screens is primarily
a pointer/wrapper to a method in a module in the Extensions directory.  The
Edit button in essence acts similar to the reload(module) function in
Python.

Basically, Zope (and Python) don't have a way of knowing the code in a
module has changed unless it's explicitly reloaded, which is a good thing.

Well this is how I understood the process.

Basically the code is read and exec-ed and the the func_code
func_code.co_varnames are extracted. Then they apply all the clever tricks
to turn the function into a valid Zope method, by (I assume) creating a
Zope method and replacing its func_code and the associated func_defaults
and arguments with the ones extracted from the external function.

The relevant code can be found in
Zope/lib/python/App/Extensions.py and
Zope/lib/python/Products/ExternalMethod/ExternalMethod.py

External Methods are (to the best of my knowledge) evaluated and their
compiled code is kept in process memory (effectively cached) the first time
the object (the External Method object pointing to a particular
module/method) is activated.  It is removed from process memory when the
object is de-activated.

This is kindof a tricky process and may be effectively cleaned up in the
near future so I won't go into too many details here.  An important thing
to keep in mind is (again, this may change soon) that the compiled code is
kept locally in each External Method Object.  If you have two EM's in Zope
pointing to the same code, you have to use the "Edit" button on _both_
External Method objects to effectively reload it.

When you say that you made it so that Apache handles the authentication,
I take that to mean you have created a .htaccess file? If that is the
case, Apache will always prompt for the password and check it against
your password file. If you use mod_rewrite to let Zope handle authentication,
you will not see the password prompt for resources that are available
to anonymous users.

data, it says 'data entered' but nothing ever shows up in the data view.
Has anyone fixed this?

BTW, I couldn't find an author name listed anywhere.

Hello Zopesters:

Are you confused by the subtleties of DTML? Want the skinny on advanced
DTML tricks and gotchas? Check out my advanced DTML HowTo:

http://www.zope.org/Documentation/HowTo/DTML

This document explains in detail the concepts behind advanced DTML tricks
like indirect variable lookup, setting variables, calling sub-templates
with different client objects, etc. Its main emphasis is on understanding
how DTML uses a namespace stack to manage variable lookups.

Enjoy and send me your feedback.

-Amos

P.S. Probably at least some of this material will be incorporated into the
DTML User's Guide in the future.

Thanks! Although by now I knew most of what was mentioned (though it
sure was nice seeing it all together in one place) this will be
invaluable for people who want to get up to speed with DTML.

Excelent! This is so much clearer than isolated answers to 'how-do-I'

Message-ID: <Pine.LNX.4.04.9903111551260.32022-100000@dolemite.psionic.com>

Hello,

I've looked through all the docs, FAQs and threads of the Zope list for
some of these answers and haven't found a clear method described. I'll
apologize now if the questions seem obvious, but I'm new to deploying Zope
on a web server and need some initial Zope setup guidance.


Question 1: 

Under Zope, what is the proper way to configure the website so users can
simply go to http://www.example.com instead of:

http://www.example.com/example
http://www.example.com:9673/
etc.

My understanding is that the mod_rewrite rules will have to come into
effect here. Will I also need to do a re-direct of some type? I need
some way to direct all URL requests so they are re-written to point to the
correct Zope folder. The ideal for me is to have a series of folders in
Zope that contain separate websites. The sites can be virtual hosted as
needed (although right now I'm only running one site). I can't find a
clear description of how to make this happen. Also I don't want to run a
separate Zope process and proxy people to the port. I want to have
everything running on port 80.

I'll have to agree with other posters that a tutorial on the design of
the actual Zope site with Zope would be very helpful as they are using a
layout of html and hierarchy that is very similar to what I'm pursuing. In
fact if someone could provide me with a description of the config they're
using it would be a huge help.


Question 2:

Under .DTML construction of links is it generally considered "better"
Zope practice to reference the entire URL or the Zope object hierarchy
directly?

Question 3: 

I don't want tracebacks to appear under any circumstances to the end
users. I haven't tried anything to counter this yet, but wanted to know
what some others have done. Would an approach to this be a try/except
positioned in the standard_html_header and footer files? Ideally I would
like to catch all exceptions and have it automatically mail the exceptions
to the webmaster instead of showing the user (In fact I think this would
be a good feature for the product). 

Question 4:

Has anyone pursued a security audit of the Zope code? I've been
considering doing this (not that I don't trust the Zope developers,
it's just that I don't trust anyone) and would like to work with
others if possible. Several of the sites I admin get hacked on very
frequently and I'm a little nervous about replacing static web pages with
no CGI running anywhere with the exact opposite end of the spectrum with
Zope. :) 

I'm also going to prepare a document describing how to run Zope
in a chroot() environment under UNIX to increase security. I'll let the
list know when it is complete.

Thank you for any responses,

-- Craig

I'm new to this list.

It seems to me that the www.zope.org is rather slow this week.  Documents
are taking far too long to be parsed.  Pings seem reasonable, so I am
expecting that the server may be receiving a lot of requests and being
overloaded (maybe from the Web Review article).  So I am just wondering what
the specs of the system that the www.zope.org ISP is using.  Also wondering
about stress tests and benchmarks for the Zope system.  (It must also depend
on backend systems etc)

Hi,

	Using Zope 1.10.2 on Win95, I was trying to set permissions on
a DTML Method. I was trying to set everything except "View" to the
Acquired permissions. View was turned on only for "Manager" and "Editor".
When I click the change button after setting things as I just described,
I get the following Traceback:

If I'm not doing something foolish here, I'll submit this to the Collector.

Thanks!

Use Apache's VirtualHost ability...
Look here for more info: http://www.apache.org/docs/vhosts/
An example:

# in httpd.conf

# your ip
NameVirtualHost 192.123.44.3

# your standard host.domain (this must come first)
<VirtualHost 192.123.44.3>
ServerName your.standard.name
DocumentRoot /home/httpd/html
</VirtualHost>

# one or more extra virtual hosts
<VirtualHost 192.123.44.3>
ServerName your.zope.name
DocumentRoot /home/httpd/html
RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 \
	[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

I'm the guilty party (!)

I found this problem before but so far haven't found the fix.... here's what
I originally posted to the list.

I'd like to get this sorted out as I'm also working on a Souped (Zoped?) up
version of Amos's poll product, which produces pie-chart gifs in response to
the poll results, but it also broke in much the same manner going from 1.9
to 1.10. So any help on this matter would be much appreciated!

Cheers,

Andy.

Subject: RE: [Zope] Guestbook Product


I get the same thing :(

Hmm.. looks like DocumentHandler no longer exists.

I've taken out DocumentHandler from the Guestbook, to mimick the change that
has been made to 'Folder' going from 1.9->1.10. When doing the guestbook, I
kept making sideways glances to Folder.py to see how it was done ;)

The book no longer crashes but I'm getting some other wierdness. The
guestbook is a folderish product which contains two documents that the user
can add to change the appearance of the guestbook. They're added by the
following lines in the 'add' method ...

        # Add a Document used to view previous entries
        fileName = os.path.join(prefix,'index.dtml')
        index2 = open(fileName,'r').read()
        i = DTMLMethod(index2,__name__='index_html')
        print "i is %s" % i.meta_type
        i.title='Change me to determine how entries are viewed'
        self._setObject('index_html',i)
        print "ObjectItems is %s" % list(self.objectItems())

The added objects no longer seem to be showing up in objectItems().

The debug statement, when run on 1.9 prints out the newly added object in
the call to 'objectItems()', while on 1.10 it returns an empty list. Is this
a side-effect of the removal of DocumentHandler? I thought that _setObject
was being inherited from ObjectManager, so wouldn't be affected by the
removal of DocumentHandler.

Cheers,

Andy.

Well, under RedHat 5.2, mod_rewrite is a DSO, and is activated
in the *middle* of the httpd.conf.
I had the same problem. The rewrite rules put a the top of the file
have no effect because they occur *before* mod_rewrite is activated.

I had to put the rewrite rules a the end of the file.
I works now.

I don't know if this will solve your problem, but, just in case...

Hello,

Correct me if i'm wrong: one has got to have "access content informations"
permission to be able to write:

<!--#with Folder--><!--#var title_or_id--><!--#/with-->

right? I've been bitten with that, and once i gave "access content
informations"
to the Anonymous User, my problem went away.

Also, before I submit this to the Collector, is it normal that the "use
mailhost services"
doesn't appear in the security tab of the folders? Each product has its
permissions
that are listed, but nothing with the mailhost object.
I had to change it directly in the mailhost object.
If it's normal, it means that i can't give global permission for mailhost
objects???
What confuse me, however, is that the mailhost object claims to "acquire"
permission
settings from its parents, but nowhere in its parents i can define the
permissions.

Hi all ,

We try to use DocumentTemplate not for HTML dynamic generation but for
C++ generation. For convenience, and because we are familiar with Python
we intend to use the Alternate Python String Format Syntax. The
generation code is beautiful compared to our previous output.write("blah
blah.... ") instructions.

Reading the docs, looking at the Zope site, this behaviour doesn't seem
to be shared by a lot of zope users. Moreover the Alternate Python
String Format Syntax  is poorly documented, and DTML features seems to
be usable but the way they can be used seem very strange. Basically our
needs are to use conditional structures, iterative structures and to
call methods. The last point seems to be the hardest one. The following
code shows a way to call python methods in python strings but 3 persons
during half a day have been necessary to find it out.

I suppose you can imagine my questions :

Is there a natural and convenient way to find out PSFS expressions going
from their DTML equivalent  ?
Is there a complete documentation on PSFS syntax ?
Are the features of DTML and PSFS identical ?
And the most important :
Do you encourage us to keep on using PSFS instead of DTML ?

Thank for your help

Well you were both right. I have turned on ExecCGI for my standard
cgi-bin directory, where I placed a copy of Zope.cgi. It is NOT
neccessary to add <Directory> statement for /usr/local/zope/ (I thought
it was neccessary... so I'm writing it here for the upcoming FAQ). Also
I thought that I should use http://www.domain.com/cgi-bin/Zope.cgi
address, which brings the introductory screen (that fooled me) but does
not allow authorization. The correct address is of course
http://www.domain.com/Zope, since that's what the rewrite rule is about. 

Thanks to all who helped me!

Hi Ron.  Just a guess, but how about having the tree tag pass in the the
current level as an argument to the same SQL method, then have the SQL
method adapt itself based on the argument?  Remember that an SQL method
can embed logic and act like an object using DTML.  For instance:

<!--#if "level==1"-->
  select ...
<!--#elif "level==2"-->
  select ...
etc.

The installer for the Zope NT binary asks you if you want to run as a
service -- in fact, that's the default.  Take a look at the file
"doc/INSTALL.txt", under Installation on Windows, for more information.

I'm not sure if the Zope universe is big enough yet for that.  I rememer
Guido doing this for Python about a year ago and nobody showed up. :^)

Perhaps if there were coordinated events?

I think the answer will certainly be yes.  Go to:

I do hope there is. If implemented like the Apache JServ module
(http://java.apache.org/) it should solve a lot of problems for everyone,
adding performance to boot.

JServ is in effect a separate process (like Zope) that receives it's
request via the Apache server, with the help of a module, that translates
the requests into socket calls.

If someone modifies the module that comes with JServ to call the Zope
process instead of the JServ process.....

HI all,
In my quest to figure out how Zope works, I'm starting with ExtrenalMethods.

I've moved slashdot.py into Extensions and set up an external method 
(id: get_headlines, funstion name: get_headlines, python module: 
slashdot).

My 'calling' DTML is a method (slashdot_headlines) with the following;
<!--#call get_headlines-->        
<!--#in headlines mapping-->
<p>
<a href="<!--#var href-->"><!--#var title--></a>
</p>
<!--#/in-->             
trying 'view' on this method gives the following;
<!--
 Error type: 
 Error value: read-only buffer, class
 -->
...
<!--
Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module

-->

I *did* have a problem with using a proxy, but got around that by 
adding this line to slashdot.py (just before the urllib.urlopen() 
call).
urllib.URLopener(proxies={'http': 'http://cache-box.you.domain:your_port'})

What am I doing wrong?
many thanks

A mod_pcgi Apache module has been discussed.  It would certainly
be more efficient.  One of the issues would be whether pcgi
should get out of the process launch business, which would
simplify a mod_pcgi and make it easier to debug.

Ok, I'll check that out.  My experience has been than I run it with
start.bat and when I close that ms-dos window zope stops.

If your external method is called from DTML document 'foo' then something
like this should do it (untested):

def mymethod(self):
	if not self.hasProperty('myproperty'):
		self.manage_addProperty('myproperty','hello','string')

BTW you can achieve the same effect from DTML

<!--# unless myproperty-->
<!--# call "manage_addProperty('myproperty','hello','string')"-->
<!--#/unless-->

This is a buglet in ExternalMethod where an exception has been raised and
caught by ExternalMethod, and EM is looking at the values of the traceback
for some special conditions.  It's trying to do a string.lower() call on
one of the values that in Python1.4 was always a string, but in Python1.5.x
is an instance (in Python 1.5, standard exceptions became classes).  This
has been fixed and will be in the next release.

Welcome to the list Andrew! I'm glad you found my suggestions
interesting enough to check Zope out. Regarding my last email, did you
figure out how to do PUT and GET from DW yet? And do you know if
Macromedia is going to add WebDAV support to DW?

In case you missed it, I'd like to point you towards the Advanced DTML
Howto:
http://www.zope.org/Documentation/HowTo/DTML
as that has more thorough information than the DTML guide I showed you
before.

I would also be interested in a newsgroup, as I am currently filtering
the email into a folder and sorting it by thread, but a newsgroup would
let me see the the same threaded view from home, as well. This would
also have the effect of letting new users see the context of the current
posts.

Subject: [Zope] Access Control Advice
Message-ID: <Pine.LNX.3.96.990312123932.13260A-100000@taos.kavi.com>

Hello all,

I am working on a Zope app, and would like to see if anyone has any tips
for how I should handle access control in this situation...

The site is a corporate organization site. It has many corporate members,
each has an admin which has control over a subset of information kept in a
relational database.

I want to have just one role (comp_admin) for this. But each company can
only have access to their company info. Thus I need to check that the
admin belongs to that company. (there are also regular users who also have
to login. they can view, but not modify)

The users, passwords and roles are kept in the database too (UserDB).

Each company has a unique id, and this is the primary keys in the DB. Each
user is associated to the company using this id (a field in their table). 

Make sense?

My current idea is:

1. Have a general main page which both users and admins login to. If they
use the admin login, get their company id (comp_id) and create a link to
the admin section using the magic of direct traversal (this way they can
bookmark the admin page). Eg.

<a href="/comp/1/admin/">admin section</a>
('comp' is the zsql method, 1 is the comp_id, admin is the folder)

Thus the comp_id of the company will be available, and I could:

A. I could then (mabey?) use the comp_id in the UserDB query (in the admin
   folder) to only retrieve those people belonging to that company.

OR (if I can't get to the comp_id from the UserDB query).

B. I could then compare to the person's comp_id to the company's comp_id 
   in each of the effect pages via a new standard_header.

Thoughts? Better ways to do this?

I haven't tryed this but on pg 10 of DTML Users Guide check out:

maketrans(FROM,TO)
and
translate(S,TABLE[, DELS])

it seems to do character for character translations.

Brian built a pretty cool way to hook SQL entries to particular
folder trees for the PDMS.  Each folder has a uniqueid which is
stored in a sql table, along with the folder parent heirarchy, when
an item is added to the SQL database.  This allows each folder to
easily identify which SQL entries belong directly to it and which
SQL entries belong as children.  This allows one to easily do things
such as count the number of SQL items which are identified with a
folder tree using SQL query syntax.

Brian also provided dtml methods to move folders and their
relationships around in the Zope heirarchy quite nicely. The
mechanism holds quite a few SQL items in it and there has never
been a need for a Python or SQL god to do any maintenance on the
system at that level.

However, it does use both SQL and External Methods. So, don't
believe that just because something requires a fairly deep level
of competence to create that it requires that same level of competence
to maintain (me for example :^).  That's simply one mark of a decent
implementation.

Subject: [Zope] sequence of numbers
Message-ID: <9903121826.ZM7584@saab.coinet.com>

This may be a newbie question, but I've loked thru the doc and didn't
spot any obvious way to do this, short of an External Method.

What I want to do is given a limit number, iterate over a sequence of
DTML commands. This would be an obvious use for #in (which I'm using
elsewhere for other things) except I don't have a sequence - just the
number of items in the sequence, as it were.

In psuedo-code, what I'm after is something like this:
	for (i=0; i < <!--#var max_items-->; i++)
	{
	  // some DTML/HTML code using "i"
	}

Now if, given a #var, I could get a list - e.g.:
	<!--#var max_items--> --> list = [0, 1, 2, ... max_items]
or [1, 2, ... max_items], it doesn't make much difference.
then I could just use:
	<!--#in list-->
	// some stuff using <!--#var sequence-index-->
	<!--#/in-->

Is there an easy way to do this? Is there *any* way to do it?

Subject: [Zope] User Profiles?
Message-ID: <Pine.LNX.4.04.9903122303421.21162-100000@zeus.carolina.rr.com>

I am working on a web site for a local outdoors group. They have about
1,000 members and are growing fast, but their web site needs help. I had
lunch with their leader today, and strongly advocated the use of Zope to
redo their entire web site. He loved my ideas, and gave me the go ahead on
the site.

Now, my first question (I'm sure I'll have many) to the group is: How do I
create user profiles? Each user of the system needs to have specific
information associated with them including: full name, address, telephone
numbers, a picture (gif or jpeg, easily uploadable by the user), their
interests, a history of the events they've sponsored and/or attended, a
buddy list (basically just a collection of other member ids), and so on.

I have downloaded the UserDb product, and figure I might be able to extend
it to support the extra columns I require. However, a big part of me wants
to keep as much of this in Zope as I can. I like the idea of the
objectstore, and don't necessarily like having to fudge SQL tables every
time I add or remove an attribute from the profiles (not that I will be
doing that, necessarily).

What do those with a higher Zope Zen Rating than I suggest in this
situation? I'm also going to be making an Events Calendar, which is
connected up with all the User information (who's running the event, who's
signed up to attend, etc.). Is all of this something that Tabula would be
good for? If so, who do I have to sleep with to get it? :^) 

I am willing to write up a case study, testimonial, contribute any code I
write back to the community, etc., whatever is requested. I just want to
do a good job for these guys, making myself and Zope look good in the
process.

HELP! *grin*

I can see a  number of things that DW will (I think) do to  help out
Zope - but there is one item in the way - FTP support
There is no direct way for Dreamweaver to send pages back to Zope
without either writing to a filesystem via a LAN or by using FTP (no
webdav yet).

So my question is this - when will we get ftp support in zope? (not just
alpha).

I am looking at the dtml spec right now and thinking about building
drag-and-drop objects for DW that talk zope.
One thing I need is for someone on the zope team or elsewhere to help me
test these so that I get the syntax correct.

Recent notes about Lynx notwithstanding, I agree.  It's extremely
frustrating when debugging the security of an app!  Zope _CAN_ use a
cookie-based authentication scheme with the UserDB product.  UserDB uses
Database Adapter (e.g., Oracle) to connect to a store of user info
(e.g., userid and password).

I can imagine some motivated community member taking a look at the
current incarnation of UserFolder and UserDB and cookie-ifying the
UserFolder.

Since DTML already has at least two different syntaxes, would it 
be hard to give it another one, that used 'regular' tags? For getting-
user-acceptance purposes it would be really good to work with as 
many HTML editors as possible, even lame ones.

Having written the above, now I see that Jeffrey said it was a 
problem "with the current syntax" in his post.

Sorry if I'm raising a point that has been covered in a more 
intelligent way already. There are just so darn many messages on

As I understand it, Zope hands the data stream to PCGI who then, outside
of the Zope process trickles the data to the consumer.

Here's a brute-force way to do it, as long as the list of items was
short:

<!--#call "REQUEST.set('foo',['1',
                       '2','3','4','5'])"-->

<!--#in foo-->

That's fantastic!  Well there are lots of people on the list that are

I predict we'll have something like this called a Membership System,
say, May 18th for a first cut.

If my previous history of fibs, spinning, obfuscation, and downright
lies makes you suspicious, or if you distrust my poor prognostication,
I'd suggest that you take the user objects in UserFolder and turn them
into extended DTML Documents, or perhaps even Folders.

There are many ways to do this, as you might imagine given
that Zope is a fully programmable environment. One such way
was done by Andy Smith (cc'ed on this reply) in building an
"alumni community site" for our (Andy and my) old
department. The site is http://www.ged.org. Unfortunately,
you won't be able to see much, as it's a password protected
site for members (there are two public pages). However, on
one of the public pages, you will note that it was the
intention all along to publish the source to the site for
the Zope Community at large.

As functional as the site is already, I think Andy had some
very cool extensions in mind before opening it up to the
public. Still, he can easily ship you the GEDUserFolder that
he built to keep track of everyone's contact info (easily
extendible to all of the fields you have in mind). As a user
of the site, I can assure you that it's a breeze to use!

Perhaps, this will also be incentive enough for Andy to
polish off some of his other goodies and release them :-)

Andy's stuff above is all kept in the Zope DB :-)

Tablua, what's that? Just kidding, it's now called Z Tables
:-). For the moment, we are actively selling (without
actively promoting) Z Tables. While you get the source, it
is _not_ an Open Source product. The license does not permit
redistribution of any kind, and does not permit derivative
works, etc. It does, however, permit you to use it to
operate any kind of website, including a publicly accessible
one, etc... The price is dirt cheap for the functionality
(IMHO). The license also has a clause that specifically
permits Digital Creations to eventually release Z Tables as
Open Source(tm). Meaning, when we're ready to release it,
don't be mad that you paid for it when others get it for
free... This is important, because it is our intention that
over time, the vast majority of our stuff will be Open
Source!

So, why do we charge now? A few reasons:

1) The docs are really weak. Rather than get beat up in
   public for it, we have a license clause that forces you
   to acknowledge that the docs are weak, and that you need
   to be able to read source to really understand the full
   power.

2) Support. Everything that we put out there causes a
   certain amount of extra work. The more sophisticated the
   code, the more work. Z Tables is _hot_, so if it were out
   there in its current form, everyone would want to use it
   (trust me on this one!), so it would become a support
   burden for us. Pay us for the product, and it's worth our
   while to support you!

3) Before putting out something to the world, we really want
   to make sure it's been beat up. It may sound strange that
   we would charge people to help us turn something into a
   polished product, but it's already powerful enough to
   solve real problems, so motivated users are our best bet
   to help us achieve our goals for a more general release.

See some earlier posts from people who have recently gotten
Z Tables! For example, check out a recent
"performance-oriented" post by Theodore Patrick of
Indigo Networks!!!

Subject: [Zope] INSERT Syntax with Zope & ZPyGreSQLDA
Message-ID: <87hfrp1js9.fsf@eurythro.savigny.stp>

Hello,

I'm trying to use PostGreSQL with Zope, but I'm having
problems using the SQL INSERT method in Z methods which
require parameters.

For example, I make a Z SQL Method named 'foo'.
In it:
INSERT INTO messages
VALUES
  (<!--#sqlvar auteur type="string"-->, 
   'blahblahblah', 'now', 'f')

I write the name auteur in the 'arguments' form.

Next I create a DTML document with:
<form action="foo" method="GET">
Auteur: <input width="30" name="auteur" value=""><br>
<input type="submit" name="SUBMIT" value="Envoyer">
<form>

When submitting the form, it displays me a new page
(generated by Zope) asking me again the auteur parameter,
as if the auteur variable wasn't passed to the Z SQL method :-(

Someone posted a mail recently with an example use
of INSERT, where he put '(auteur)' after the 'INSERT INTO messages'
text: INSERT INTO messages (auteur) ...

When I try this, I get:

Error, pg.error: server fatal error. Please report to your db administrator. 

SQL used:

INSERT INTO messages (auteur)
VALUES
  ('testing again', 
   'blahblahblah', 'now', 'f')

Is there something specific to PostGreSQL ?
(Using Zope 1.10.2, PostGreSQL 6.4.2, PyGreSQL-2.2, ZPyGreSQLDA 0.02)

I looked in the Z SQL Method User's guide, but nothing is written
about adding data to a DB :-(

A good to test your SQL is using psql.

And upgrading to PyGreSQL 2.3 or later, which return proper sql messages

This is definitely wrong ;(

something like 
INSERT INTO messages (auteur,title,bookdate,any_good)
VALUES
  ('testing again',
   'blahblahblah', 'now', 'f')

might have worked. You may also mean current_date or current_time 
instead of now or now()

I didn't find any other way, either. But here's an External Method you can
use.

--- begin loop_range.py ---
LoopRangeError = 'LoopRangeError' # Name an exception class.
loop_range_limit = 100            # Maximum allowable loop index.

def loop_range(max):
    if max <= loop_range_limit:
	return range(max)
    else:
	raise LoopRangeError, max
--- end ---

Notice that it won't allow the "max" parameter to be bigger than 100. This
prevents users from generating near-infinite amounts of HTML and freezing
your server. You can edit this to any value you like, or even remove it if
you trust all your DTML authors.

Now, create an External method with the following properties:

  id:     loop_range
  title:  Loop Iteration Method
  method: loop_range
  file:   loop_range

To use this method in DTML, try the expr attribute of the #in construct:

--- begin sample DTML ---
<!--#in expr="loop_range(max=50)"-->
<P>Index: <!--#var sequence-item--></P>
<!--#/in-->
--- end ---

> Is there an easy way to do this? Is there *any* way to do it?

Yup. ;-) Zope has tons of power hiding under the hood, and a skilled Python
programmer could make it do almost anything.

One way of doing this would be using an external method:

def MyRange(iMax):
    return range(iMax)

The property bobobase_modification_time gives you the last modification
time. This is not in the docs, I gleaned it from Zope's source (it is used
in amongst other places the document edit screen). This is a good item for
the FAQ.

Subject: [Zope] Bug in sqlvar.py?
Message-ID: <Pine.LNX.4.04.9903132129250.14974-100000@zeus.carolina.rr.com>

Hello, everyone. I'm bustin' ass on my project for the outdoors group and
ran into a problem with the #sqlvar command.

At the top of the file, in the docstring, it says:

    For example, given the tag::

      <!--#sqlvar x type=nb optional>

    if the value of 'x' is::

      Let\'s do it

    then the text inserted is:

      'Let''s do it'

    however, if x is ommitted or an empty string, then the value
    inserted is 'null'.

Either I'm totally off base somewhere, or this is not correct. In one of
my SQL Methods I have a query, with a line:

  <!--#sqlvar address2 type=nb optional-->

And, when I submit the query while leaving address2 blank I get:

  Invalid empty string value for address2

When reading the code, beginning on line 200 there is the else case which
handles values of types other than int or float:

        else:
            v=str(v)
            if not v and t=='nb':
                raise ValueError, (
                    'Invalid empty string value for <em>%s</em>' % name)

            v=md.getitem('sql_quote__',0)(v)
            #if find(v,"\'") >= 0: v=join(split(v,"\'"),"''")
            #v="'%s'" % v

There is absolutely no check for the optional flag in this case as there
are in the cases for int and float. Is this check supposed to be handled
elsewhere in the code, and never make it here, or is this an oversight? I
can patch it to fix the problem quite easily, but if this is not the
preferred way of doing things I'd like to know (to avoid patching it every
time a new Zope comes out.)

I have two address lines, address1 and address2. I just want it to set
address2 to null if the user does not fill it out. Is that too much to
ask? :^)

As I said, if I'm blatantly overlooking something, please let me know. If
not, I'll be happy to submit a patch and/or report this in the collector.

Thanks. Hope you all are having a good weekend!

Hello all, 
First let me start by saying I've finally cleared time to play with zope.  
Its coming along nicely but I've hit a snag.  The following snippet in a 
form:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<!--#in qryListStaff -->
<OPTION VALUE="<!--#var user_id-->"><!--#var user_name-->
<!--#/in-->
</SELECT></TD></TR>

using MySQL produces the following HTML:

<TR><TD ALIGN="RIGHT">Staff</TD><TD><SELECT 
NAME="bugs_tbl.staff">
<OPTION VALUE="2L">Alan Johnston
<OPTION VALUE="1L">Tom Jenkins
</SELECT></TD></TR>

Now unfortunately I believe the L is causing the insert to fail with an 
invalid integer.  I specified user_id as integer unsigned zerofill 
auto_increment.  Does anyone know why the 'L' is being return?

TIA

The L value is caused by a long integer to string conversion. You can get
rid of the L by specifying a C format string, like so:

<!--#var user_id fmt="%u"-->

Ow you're right. But this hasn't changed anything, it still
ask me for the parameters after clicking on submit :-(

In the HTML form, I replaced the action with 
'<form action="add_message/manage_test" method="get">'

where add_message is the Z SQL method. And it adds correctly the
record to my Database, but displays 'This was not a query'.
And, well, I don't think taht's the correct method to add records,
by using the test method :-))

Is there anywhere an example of product adding some records to
a database ?

What's the difference between now and current_date / current_time
I tried all of them, and they give exactly the same result 
(the good date :-)

Message-ID: <199903141232.XAA17000@mbuna.arbhome.com.au>

Short Version of message: ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now 
available from http://www.interlink.com.au/anthony/python/

I'm looking for opinions on the LDAP zope product I've been building.

Right now, LDAP connections work, LDAP Methods work, but there's still 
a bit more to do. Right now, the following is unimplemented:

In ZLDAPconn:
. Anything other than simple_bind(who, passwd) for connecting to the 
    LDAP server
. meaningful doc strings

In ZLDAPMethods:
. Pluggable Brains
. Result Caching
. Limits on the number of results
. Variable interpolation in the filters, and in the base DN
. modify or add queries (only search is supported right now)
. meaningful doc strings :)

Other stuff:
. UserLDAP is not finished yet (or released) - the primary issue is the
    storing of roles and domains. Right now this would have to be some
    non-standard LDAP attribute... but what should it be? It also probably
    needs modify and add added to ZLDAPMethods before being really useful.

Things I'd like comments on:
For ZLDAPconn:
    what other bind methods would you like to see?
For ZLDAPMethods:
    how should add/modify/query be distinguished? Separate methods?

I had planned to get variable interpolation working tonight, but decided I'd
rather get an early night. Probably tomorrow evening, instead. Stuff I hope to
get going in the next day or so: variable interpolation, pluggable brains.

Anyway, ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from 
http://www.interlink.com.au/anthony/python/

It requires David Leonard's ldapmodule, from 
http://www.it.uq.edu.au/personal/leonard/dc-prj/ldapmodule/

It's been tested on Linux 2.2, under Zope 1.10.2 and ZServer. Assuming the
ldapmodule works on other platforms (it's available in source, and also as
a windows .pyd) it should work elsewhere, too.

Try something like:

<form action="add_message_result" method="get">

And then create a DTMLDocument or DTMLMethod called add_message_result
like this:

<!--#var standard_html_header-->

<!--#call "add_message(REQUEST)"-->

<h2>Success!</h2>

<p>
  Your message was added successfully! Thanks!
</p>

<!--#var standard_html_footer-->

The success message will only be shown if the query succeeds, because it
is below the #call statement.

Hope this helps!

thanks guys that was exactly the problem and the above fixed it.  I

The docs seem to imply that you provide fsdir with a *directory*
ie fsdir=/web/srvs-sol/www.so.cz/ppm

Subject: [Zope] ZAP
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC61@peter.sths.org>

How can I configure ZAP so that all http requests go through the cgi?
Zope is the only thing running through this apache, so I don't want
everything on the site prefixed with Zope/ (or anything else, so no, I
don't just want to know how to change the prefix). This is basically
what is keeping me on ZopeHTTPServer. 

BTW, running ZopeHTTPServer multi-threaded worked well for about 15
minutes. Then suddenly certain pages wouldn't load. I stopped and
restarted the server, but the pages still wouldn't load. I also noticed
that if I stopped Netscape and hit reload, it would cause several new
ZopeHTTPServer instances to appear, and doing so again would continue to
create new instances which never seemed to dissappear. Are these locking
the items they are downloading? The behavior I saw seemed consonant with
it locking the item it was downloading, then failing to recognize the
netscape had disconnected, and thus never removed its lock. When I
restarted it single-threaded, all the pages came up without a problem. I
would really like to move to Zap, but I can't afford at this point to
have the URL of the page change. 

How can I make a Zope pcgi accessible as the root of a Zap install?
Please help.

I've imported a directory using fsimport and it worked for me. I can only
suggest (clutching at straws here) that having '.' in the fsdir attribute
might be throwing it?

Even more clutching here - did you leave the trailing slash off the fsdir
attribute?

In lib/python/StructuredText/StructuredText.py, modify the ul() and ol() methods
as follows:

Change:

  if p: p="<p>%s</p>" % strip(ctag(p))

to

  if p: p="%s" % strip(ctag(p))

I posted a more robust diff to the zope-dev list last night, which allows

Subject: [Zope] Simulating static URLs, end-user session management
Message-ID: <36EC3A7B.53817A8D@erols.com>

Hi.  I am very new to Zope, having spent the last day
(with only about two hours of sleep) excitedly pouring through
the documentation.  I still have a lot to digest, but
there are some questions I did want to ask at this stage:

A)  Are there reasonable ways of arranging to have
    the URLs for some/many Zope generated pages appear, as
    far as the outside world is concerned, to be URLs
    for static HTML pages?  

    The issue is one of indexing by search engine robots.
    I anticipate building a site where most of the 
    content will change fairly slowly, and where there 
    would be a standard set of views of the data which 
    would be essentially static at a logical level.  I 
    really want search engines to index those static 
    views.  (There would likely also be dynamically
    generated views which shouldn't be indexed.)

    So, I think the requirement is that there should be a
    way of getting to pages with a URL like:

	http://www.mydomain.com/here/there/everywhere.html

    as opposed to

	http://www.mydomain.com/here/there/everywhere

    or

	http://www.mydomain.com/here/there?everwhere

    I supect there are a number of ways of tricking Zope
    into accepting URLs in the first form, or perhaps
    into actually generating some static pages which would
    be served up directly by the HTTP server (though
    my quick check of the archives suggests this is an
    unresolved issue). My questions are:

    1) Has anyone already done something like this?

    2) What approaches could you suggest to accomplish
       this?

    3) Is trying to arrange this likely to be a big task
       or a little task (as subjective as that question is)?


B) On another topic entirely, I am wondering about the issue
of tracking sessions of end-users.  (Hmmm... maybe I should
have done more searching in the archives -- this must be
a common issue.)  Various application servers (e.g., for
Java servlets) that I've looked at provide facilities
for maintaining "session" information (not in the sense
of a transaction as used in Zope) about end users.   Typically
this would be done by setting a cookie or by incorporating
a session ID into dynamically generated URLs.  I haven't
noticed anything about this in the Zope documentation.
I'm guessing that perhaps that is because Zope is so
powerful that implementing something like this yourself
is regarded as trivial.  But thinking about it a bit,
I'm not sure what the Zope mindset would be about how
to do this.  Zope sends requests directly to objects.
But in order to manage a session cookie (or whatnot)
you need to add a certain functionality to every (or
most HTTP) requests.  You certainly don't want to have
every object explicitly worry about this.  Is there
a hook that would allow all requests to
pass through some sort of filter that extracts/manages
session information?  Or is there some other standard
solution to this problem?


For what it's worth, I am interested in using Zope
to build my second E-commerce site.   I built the
first site by using Python to generate static pages
from a data structure, combined with lots of JavaScript
and a little Perl CGI.  It worked, but I'm sure there
is a better way.  I was leaning towards a Java servlet
plus templating package solution, until I found Zope.
I've been a Python proponent for a while, but Zope is 
threatening to make my brain explode.  Talk about 
paradigm shifts. 

C) Despite my Python and OO background,
it's not easy to absorb it all at once.  This does
make me somewhat concerned, as my business partner,
who will be a content provider, has no OO experience.
I don't want to produce a system where it will be
hopeless for her (possibly with help from another
developer) to take over if I get hit by a bus.
Thoughts...?

Robert,

I'm only going to address your last point, but it's 
something I feel strongly about.

Let's ignore the technical issues, except to mention
that only you can judge is Zope is appropriate for
your situation.  Fortunately, you have an excellent
opportunity to discover its relative strengths and 
weaknesses.

One of the important secondary issues (some would 
claim the primary) about Open Source is that it
protects your business against the "What happens if
Robert gets hit by a bus?" scenario.  Digital Creations 
is in the business of providing support to organizations 
that use its products.  Heck, in this sense it's even 
superior to key man insurance.

Furthermore, because of DC's courageous decision to 
release Zope as Open Source, not only is your company 
protected against *your* untimely demise, but it's even 
secure against the day Hadar decides to transfer all 
the company assets into hedge funds.

Best regards,

Message-ID: <EF3E7C5CCD67D211A43C006008AE49B8181FF7@JUNG>

Hi All,

As an exercise, I'm trying to get the JobBoard example code given in
http://www.zope.org/Documentation/Reference/ObjectPublishingIntro to work in
Zope (as opposed to Bobo/ZPublisher), and am having some difficulty.

Copying the PeeWee's playhouse example in
http://www.zope.org/Documentation/Reference/ExternalMethods, I placed all
the JobBoard files in zope/lib/python/shared/JobBoard, made an empty
__init__.py file, fixed up the dtml_loc variable, and put a
JobBoard_utils.py file into zope/extensions, which reads as follows:

  "utility to add JobBoard objects to folders"

  def addJobBoard(self,id):
      "Add a playhouse to the current folder"
      if not hasattr(self,id):
          setattr(self,id,JobBoard("Python Jobs"))
          return "JobBoard added with id %s" % id
      else:
          return "id %s already in use" % id

Using Zope's management GUI, I successfully added the addJobBoard function
as an external method, and have successfully called it to create a JobBoard
object called testJobBoard.

However, when I try to view the testJobBoard object, I get an error message
that reads "Sorry, the requested document does not exist."

The addJobBoard function was added as an external method to the root folder,
so my understanding is that the testJobBoard object should also be
accessible from within the root folder (that is that its URL is
"localhost:9673/testJobBoard").

What am I doing wrong here?

Also, what is the proper way to debug this sort of problem?  The output of
the zope process merely mentions a GET request for the given URL, and the
404 response code -- no further detail is given.

Thanks in advance for the help!

-Justin

In looking through my Apache configuration files, I tried to piece
together what changes I made. Here's what I think you need to do.

In httpd.conf, make sure you have these lines (I put them at the end):

Alias / /cgi-bin/Zope.cgi

# Zope configuration maps /Zope/ to the Zope.cgi CGI script
RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

NOTE: In the RewriteRule directive above, the [e=...] stuff should go
directly after the ...Zope.cgi/$1 section, with a space separating them,
e.g. ...Zope.cgi/$1 [e=HTTP...]

You will need to munge the path in the RewriteRule directive, where it
says /home/httpd to be wherever your document root is.

I did this a while back, and have since switched from Apache to ZServer to
test it out, so I haven't used it lately. However, this should work, as I
never changed the config files after I stopped using Apache.

Let me know if you have problems; I'll do what I can to help.

You say "one shouldn't have to use <!--#var "_['foo']"--> instead of
<!--#var foo-->."
However, i find it useful to write:

<!--#if "_['foo'] and _['bar']"-->
<!-- blah -->
<!--#/if-->

instead of:

<!--#if foo--><!--#if bar-->
<!-- blah -->
<!--#/if--><!--#/if-->

<!--#var "img.name"--> is the best way to go. It'll insert a IMG tag with
an absolute URL, and if it knows the image width and height, these will be
included in the image tag. Make sure you use the quotes! img.name means:
the attribute 'name' of the object called 'img'.

You can specify the image width and height by hand in the images' property
screen, but if you uploaded a PNG or GIF image, Zope will deduce the width
and height from the image itself. The next Zope release will also support
JPEG image size detection.

Yes, that's what I want. 

Maybe what I'm trying to do is against object-oriented concept? I can
see that images should be kept with the DTML page that calls them. I
just need images to be accessible by a group (role) of "image managers",
but the code that holds it to together should be accessible to an Admin
role only.

There is little reason to avoid naming your objects with the extension
built into the ID, like everywhere.html. You can then simply refer to the
object using that ID, which to a not so smart indexing bot will look like
an HTML file (but it should *really* look at the MIME-type...). The only
problem would be referencing the object, as you have to take precautions to
make sure Python doesn't try to reference the attribute named 'html' on the
object 'everywhere'.

So, as long as you name your DTML Documents that are to be indexed with the
.html extension, everything should go fine.

No, Zope has no Session tracking facilities at this moment. DC is however
working on this. At the moment you will find a 'Session' object in your
Zope distribution, but this is a different concept altogether, and will be
renamed to 'Version' when client session objects appear.

DC can be hired to help out... and as Zope is now Open Source, a growing
number of people can help out.

How about

<!--#/if-->

or 

<!--#if "_.getitem('foo', 1) and _.getitem('bar', 1)"-->
<!-- blah -->
<!--#/if-->

Yep, you got use there.... calling the Image object doesn't generate extra
information like border=0. DC is working on a solution to that, at least, I
think they said so.

For now you will have to write out the IMG tag yourself:

<IMG SRC="<!--#var BASE1-->/img/name" width="<!--#var "img.name.width"-->"
height="<!--#var "img.name.height"-->" border=0>

I assumed that the img Folder object is a direct subobject of the Zope root
object.

I was afraid it would be the case.... I thought I could use Property
somehow (adding text Property named Border with the value 0) but then I
realized that I can't interfere with it, since the rendering takes place
INSIDE while properties are OUTSIDE.

> <IMG SRC="<!--#var BASE1-->/img/name" width="<!--#var "img.name.width"-->"

Looks terrible :-) I think I rather use <img src=img/name border=0> for
the time being.

okay next qustion: I have a image under a folder called "images".
<!--#var "images.somefilename"--> should work - except that the image filename
contains the "." character (eg: "foo.gif") and this gets confused with the dot
notation of the object (it tries to find images/foo/gif and chokes with a
traceback)

So how do I get round this one?

Subject: [Zope] File upload product anywhere?
Message-ID: <v04104401b312cbb2cbde@[128.240.198.13]>

Hi all,
Has anyone written a file upload 'product' that they'd like to share?

My own requirements are that;
the files should (optionally) go to a file system,
I need to be able to change the interface for the system,
the users should be authenticated from an external database,
the files (if held in a file system) should retain their associations 
with folders (for permissions and access),
and I'd like it in blueberry please.

What I'm basically after is the best of both worlds - Zope 
permissions/acquisition etc. with the 'safety net' of a file system 
for large files (and possible batch uploading).

My problem (or one of them) is that there's no way that I'm up to 
speed enough in Zope/Python to start on this...I have a system doing 
the file upload working well in PHP3, but that (obviously) doesn't 
have the permissions/acquisition power of Zope. I guess I could do 
redirects to my PHP3 scripts from within Zope however, but it's 
hardly (ahem) 'elegant'.

any thoughts gratefully accepted.

Tone

The find management screen does give helpful hints. If you want to
implement this kind of searching, you'll have to use the same techniques.
These are however largely undocumented.

The file lib/python/OFS/findResult.dtml should give you a lot of hints on
how to implement a search command. It comes down to calling PrincipiaFind
on a Folder with the right arguments:

obj, obj_ids, obj_metatypes, obj_searchterm, obj_expr, obj_mtime,
obj_mspec, obj_permission, obj_roles, search_sub, REQUEST, result, pre

where

* obj -- base folder to start at

* obj_ids -- (optional) list of object ID's to search

* obj_metatypes -- (optional) list of meta types to search for (if the
string 'all' is in this list, all objects, whatever their meta type will be
included in the results).

* obj_searchterm -- (optional) literal text to search for in the *source*
of DTML Documents and DTML Methods.

* obj_expr -- (optional) DTML expression (as would be used in the expr
attribute of for example the var tag). If this expression returns true
within the context of an object, the object is included in the search
results. You could use this for testing on certain properties, like 'foo=bar'.

* obj_mtime -- (optional) DateTime object or string that can be converted
to a DateTime object, specifying a modification time to compare objects
against. Will on default return objects that have been modified since
obj_mtime.

* obj_mspec -- (optional) When used with obj_mspec, and set to '<',
PrincipiaFind will only return objects which have been last modified before
the date and time specified by obj_mtime.

* obj_permission -- (optional) To be used together with obj_roles. Check if
the roles specified by obj_roles have the obj_permission permission. Only
these objects are included in the results.

* obj_roles -- (optional) List of roles to check for obj_permission access.
See obj_permission.

* search_sub -- (optional) if true, search subobjects recursively.

* REQUEST -- (optional) REQUEST object, used to make sure that
AUTHENTICATED_USER is available for obj_expr expressions.

* result -- a list of objects to be included in the returned results. Used
by the PrincipiaFind method when recursively searching subobjects.
Generally of no use to us humble DTML programmers.

* pre -- prefix the IDs in the returned result list with pre and a slash.
So, when called with pre='foo', and bar is the only object found,
PrincipiaFind will return the list of tuples: [('foo/bar', foo)]. This
argument is used when recursively searching subobjects, where pre is the
relative URL of the object searched.  Generally of no use to us humble DTML
programmers.

The method returns a list of tuples, where the first element of every tuple
is the relative URL of the object found (relative to the starting point),
and the second element is the object itself.

Object name can be different from filename. Thus you name your foo.gif
file just Foo, and that's it.

Zope's object database uses Python's pickle facility, so in general
instances only store their own data, and use whatever version of the class
is available. Classes are not stored in the database. This means that when
you change your class, your instances will be updated.

>Also, is there any problem with the instances failing to work with a newer

Yes. And this is not a Zope-specific issue, or even a Python-specific issue.

Anytime you have long-lived instances and change the class, you may run
into problems. Python comes with a couple hooks to help you out. You should
look into __getstate__ and __setstate__ which are documented in the Python
pickle documentation.

Probably the most common type of problem occurs when your new class
definition assumes a new attribute which the old instances don't have. An
easy way to solve this is to provide a class attribute which gives a
reasonable default for this attribute.

For example:

class MyClassV1:
  'Original class'

  def __init__(self):
    self.color='red'


class MyClassV2:
  'Updated class'

  def __init__(self):
    self.color='red'
    self.texture='bumpy'

  def describe(self):
    return 'I am %s and %s' % (self.color, self.texture)

Notice that instances created with MyClassV1 will not have a 'texture'
attribute, so that when the class is updated, old instances will break when
you call the new 'describe' method. A simple fix is to provide a default
class attribute. For example:

class MyClassV2:
  'Backward compatible updated class'
  texture='nondescript'
  ...

Now old instances won't break in the 'describe' method.

Another approach is to test for the attribute and update the instance when
you're going to use it. For example:

  def describe(self):
    if self.texture=='nondescript':
      self.get_texture()
    ...

If 'describe' is the only place where you use 'texture' then you wouldn't
even need to provide a class attribute, and could simply test for the
absence of the attribute.

Finally you might include version numbers in your instances and test for
these, but this seems like overkill. I would suggest sticking to default
class attribute solution for most cases.

Hope this helps, and good luck.

In general, when you have trouble spelling an object's name in a variable
expression because its name is not a legal Python name (e.g.
'sequence-item' or 'foo.gif') then you should use _[] or _.getitem

However in your case you can simply get the sub-object with a plain old
getattr:

<!--#var "_.getattr(images,'foo.gif')"-->

Another possibility is to use the with tag:

<!--#with images-->
<!--#var foo.gif-->
<!--#/with-->

Since these are so ugly, you might consider the simpler manual method of
generating the img tag:

<img src="images/foo.gif">

or else you might consider *not* having a images directory, and keeping
your images in the Folders where they're used. Then you can refer to the
images directly:

<!--#var foo.gif-->

And because of acquisition, foo.gif is accessible to all sub-Folders of the
Folder it is located in, in the same way.

Well, since that's a symlink anyway, I tried to suck directly from
/home/pes/public_html. Still nothing. I even changed that dir to be
world writable.

I tried both.

I'm sure I must be crazy. I summarize what I did:
1. downloaded fsimport.py
2. mkdir /usr/local/zope/Extensions
3. chown nobody:www Extensions
4. chmod /usr/local/zope/Extensions to be rwxr-xr-x
4. copied fsimport.py to /usr/local/zope/Extensions
5. chown nobody:www fsimport.py
6. chmod fsimport.py to be rw-r--r--
7. created External method fsimport inside of ppm
8. put "fsimport" into all 4 fields (Id, Title, Function name, Python
module name)
9. http://www.sol.cz/Zope/ppm/fsimport?fsdir=/home/pes/public_html
10. error "TypeError: read-only buffer, class"

I must have missed something.

look in source code and found that in pcgiConnect() function only
socket() & connect() are present.  But where is bind()?.  When I fix
this problem I found new error message "unable to connect".  In function
pcgiStartProc I found that sigemptyset(&zmask) we use the foollowing:

	while (sigflag == 0)

So, after first iteration we have empty signal set and kill(pid,

If I wrong, please correct me.

Perhaps I'm failing to understand something.
Looking at pages on zope.org and some obviously dynamic pages
on other sites, they all return a MIME-type of "text/html".   Which I
think means that a smart indexing bot should *not* simply look at the 
MIME-type.

As I understand it, most search engine robots try to exclude dynamic
content because of the justifiable fear that once they start exploring
a web of dynamic content they could get lost in an infinite or
near-infinite search space.  I've read that as a result of this, 
search engine robots do things like refuse to index any URL with 
"cgi-bin" in the path, or which do not end in an approved recognized 
file extension.

Do you have a different perception of search engine robot policies/strategies?

Guess I'm going to need to experiment.  I'm a little fuzzy on how this

Are there any projections available re the timing of this?  I'm wondering
about how much effort to spend on ad-hoc interrim measures.

FWIW, in my mind an ideal client session scheme would allow multiple strategies.
In most cases using cookies works out for the best, but I would like to be
able to accommodate anti-cookie zealots as necessary.  On the other hand,
I don't want to clutter URLs with session-id's if I don't need to.  (I suppose
having authenticated users is yet another strategy, and one that Zope currently
seems oriented towards.  Fine if users really want or need to get into your
site or need to perform authorized operations, but not so good if you're trying 
to entice them in.)

While I expect to eventually be working under Unix

at present I'm trying to use Zope under Windows 98.

The problem is: it's not working.

I'm using the Zope HTTP server, and I can contact the
management system just fine, a prowl around looking
at everything.  But if I try to add an object (whether
it be a DTML Document, a Folder, or an "Item" from
the sample_product package (which I installed), what
happens is:

	I am allowed to fill out the form where
	you enter object creation fields (ID, title, etc.),
	but when I send that form the HTTP server never
	returns.

Any clues as to how to fix this, or debug it, or get any
idea as to what is happening?

It seems to me that Zope is rendering my HTML tag attributs in different

Looking into source produced by Zope, I found

Why is Zope doing this? Maybe there's good reason, but I'd like to know,
because too smart software is sometimes more burden than a help.

Also some attributes are omitted in the rendering process. Property
"width=106 height=106 border=0 align=right hspace=10 vspace=0" ended up
without vspace statement.

OK, here's the situation.

I have a "login" page that I want to list the contents of different
directories depending on the value of the AUTHENTICATED_USER

Each user has a folder under the folder 'user'.

I would like to be able to do (simplified):

<!--#with expr="_.getitem('user'.AUTHENICATED_USER,0)"-->
<!--#in "objectValues()"-->
<!--#with sequence-item-->
<a target="_view" href="user/<!--#var id-->"><!--#var title--></a><br>
<!--#/with-->
<!--#/in-->
<!--#/with-->

However, I get a TypeError on the #with line (and even if I put in the
AUTHENTICATED_USER.id instead of just AUTHENTICATED_USER).

What am I doing wrong here? I've tried a lot of different combinations
of #with and _.getitem and such..

 THANKS

Victor,

I think your problem lies elsewhere.  The client does not
have to bind a local address before calling connect.  The
connect() function automatically assigns an unused port
to the socket.

You will probably find the problem is much more obvious
than a low-level socket bug.  Check your Zope.cgi paths,
permissions, and Apache configuration.

Good luck.

Message-ID: <199903160352.WAA04182@mail.digiweb.com>

Hello folks,
I'm stuck on a problem which I hope some one could help me with.  I 
have a database entry form where the user will enter in information for 
two related tables.  When she submits the form, I want to first post one 
tables information, then call another sql method to get the id generated 
for that post, then take that value and add it to the REQUEST object 
and pass it to the second sql insert for inserting to the second table 
(along with some other parts of the REQUEST object from the form).  

I'm planning on using MySQL that has a special select:
select LAST_INSERT_ID()
to return the last auto-generated id value to get the id.

I know you can add a variable to the REQUEST object via
<!--#call "REQUEST.set('varname', value)"-->
but how to I get the value from the sql method?  The only way I know 
now is via #var tags but you can't nest the DTML.

I hope this makes sense...

This is something Zope can´t influence, it´s part of the way your browser

Could you supply us with some DTML examples of this behaviour? It´s not
something I´ve seen before. Is there any chance your HTML editor is doing this?

[snip external method]

I'm wondering; is there a reason why 'range' isn't accessible from DTML
in the '_' namespace? Is the reason as you indicated in your external
method, i.e. that you don't want people to generate vast ranges from
DTML?

Just curious,

The reason if of course merory flooding attacks. A range that asks for a
list of 3 billion items is a wee bit unpolite to the machine.

A way of checking would be:

RANGELIMIT = 1000

def SafeRange(iFirst, *args):
    if not len(args):
        iStart, iEnd, iStep = 0, iFirst, 1
    elif len(args) == 1:
        iStart, iEnd, iStep = iFirst, args[0], 1
    elif len(args) == 2:
        iStart, iEnd, iStep = iFirst, args[0], args[1]
    else:
        raise AttributeError, 'SafeRange() requires 1-3 int arguments'
    
    if iStep == 0: raise ValueError, 'zero step for SafeRange()'
    
    iLen = int((iEnd - iStart) / iStep)
    if iLen < 0: iLen = 0
    
    if iLen >= RANGELIMIT: raise ValueError, 'SafeRange() too large'
    
    return range(iStart, iEnd, iStep)

Maybe this should be part of the _ object. Can someone turn this into a
patch and supply this to DC? I´m a bit short of time right now.

Dear Zopists,

    This is another post to make you aware of a new source of
information for Zope. You can access #zope on the EFNet servers. Their
is an infobot on this channel that could be a great resouce, but it
needs to learn a lot about zope. If you pay a visit to the channel,
query the bot by typing:  /msg wizkid1 help. This will provide more
information on the bot.

I for one think this is a brilliant idea!

I visit the PHP3 channel on EFNET frequently, a real sense of community and
friendship can be built.

I really do hope this comes off, so let's make a go of this eh guys 8^)

Ok, two questions

1. What happened to the Zope web site, it seems to have gone down 
yesterday and still is not operating ?

2. I have downloaded ungziped and untared (Zope-1.10.2-linux2-x86.tgz), 
but the install instructions do not seem complete.  I retrieved the 
INSTALL.TXT file from the doc directory and started to follow them, but 
their doesn't seem to be any 'access' file in this distribution.  What's 
more some of the command line options come up as invalid, like -c,which 
the install program quit on saying it was a invalid option.  The -c 
option doesn't even show up in the --help for the installer.


I was hoping there would be some additional install info on the web site, 
but that's not working.

Try:

select LAST_INSERT_ID() as fred

then grab <!--#var fred-->

If this works then I know what the problem is!  :^)

If you use the database's command line tool and run this SQL statement I
bet it returns a single value (i.e., it doesn't return a table).  The DA
wants to munge and chew on rows in tables.  If think that if you use the
select LAST_INSERT_ID() as fred you'll get a one-row, one-column table
-- this is what Zope wants.

It works from where I'm at. You may want to try
traceroute www.zope.org
(or tracert www.zope.org from Windows)
to see where things are getting hung up.

The access file just needs one line of the format "username:password"
and should be in your zope install directory. Since I was using PCGI
with Zope, all I did was just untar it, make it and then copy Zope.cgi
into my web area...

Try: select LAST_INSERT_ID()+0 to cast it to an int...

Also, check your declaration for LAST_INSERT_ID().. if the above doesn't
work you'll need to either try the patch for ZMySQLDA that was posted a
week or so ago, or do something like: SELECT CONCAT(LAST_INSERT_ID()) to
cast it to a string and then use a nifty Python fn. to convert it to an
integer number. 

It seems the MySQL driver has problems with some datatypes.  There was a
patch posted befure.. I'm curious to know if it'll fix this problem...

I'm not using zope, but I'm using ZPublisher and ZServer. I'm coding a

This is in the Zope FAQ, actually, at http://zdp.zope.org/FAQ/external.
At least I think I'd apply to ZPublisher as well?

How do I return an image from an External Method?

Example (for a png image):

    def foo(self, RESPONSE):
        # set the header
        RESPONSE['content-type'] = 'image/png'
        # return the actual image data
        return mkimage()

Another way to set the header information is:

    RESPONSE.setHeader('content-type','image/png')

Martijn

You are right. I wanted to check the frame, which I can't do easily
under Netscape, so I pushed File/Edit Frame, and apparently Netscape
Composer did it, because when I do "Save frame as...", it looks O.K.

Having discovered this, there is no chance I would ever use Composer. I
would be happy to have Zope work as closely as possible with
Dreamweaver, though.

I've been using this.... (Zope example but should work with ZServer)

It was fully expecting to have to mess about with headers to get browsers to
recognise the gif, but broswers seem to know a gif when they get one!

This example returns gifs in a browser when you do ....

http://mysite/renderGif

or even

<IMG src="renderGif">

(I'm fully prepared to admit there may be better ways of doing it) ;)_

Cheers,

    def renderGif(self, size=500, counter=1):
        """Draw a pie chart"""
        im = PIL.Image.new('RGB', (size,size))

        # Do GIF manipulation stuff here!

        outFile = cStringIO.StringIO()
        im.save(outFile, 'GIF')

Why not use:

select 'id_field_name' from 'table' where 'id_field_name' IS NULL

id_field_name beeing the field with AUTO_INCREMENT set

When using Zope to publish XML documents (using DTML Document objects) I
often write:

  <!--#call expr="REQUEST.setHeader('Content-Type', 'text/xml')-->

Some part of Zope tries to guess the Content-Type otherwise. A lot of this
code is directly shared between Zope and Z Publisher, so you might see
similar behavior.

Eric

Ok, I consider myself pretty technical, but not a UNIX master, and I've

Here's what I do:

I downloaded zope 1.10.2
I unzipped and ran the installer.
It works fine to the point where it wants me to choose between running
zope alone or as a service.
I've tried it "both ways" and although I can get zope running fine by
manually starting it from start.bat, and
I make the zope service start automatically, it will not work as a
service!

I dont have any other web server on this machine and dont really care
which server I use. I had assumed that ZopeHTTPServer  would run as the
service, but it doesnt work...

Is there just a minimal way to get zope going on it's own?

I know the ip address etc. of my system, but that doesnt seem to be the
issue.

I wouldnt even mind if in the install you had an option for "install
default web server" so that zope can piggy back on it.

Does it have something to do with setting permissions to the var
directory?

All I'm basically looking for is sort of a recipe style instruction on
how to get it up and running. (With no handwaving like "now configure
your system to run the zope.exe".  Assume I'm a total idiot...

Which I'm not, but I'm still having problems.

No, I don't think that can work. You need another webserver, like Apache
(which you can download from www.apache.org, though of course it has its
own configuration hassles).

Hm..Perhaps ZServer, but that's still not stable. Can it run as a
service in NT?
 
Otherwise I'd recommend Apache; it can do plenty, though there is a
learning curve there.

Here's what I did:

I downloaded zope 1.10.2
I unzipped and ran the installer.
I chose to run zope alone
I created a shortcut to start.bat in C:\WINNT\Profiles\All Users\Start
Menu\Programs\Startup


This will start Zope every time you reboot. Note that it will not get
rid of the annoying MSDOS command prompt window.

I hope this helps

I posted a message last week about running ZServer as a service.  You can
find the message at
http://www.zope.org/pipermail/zope/1999-March/005030.html

I built my Zope from source, so I don't know if this works the same as the
self-installer version, but it should be pretty close.

1. Install Zope 1.10.2, choosing to run standalone.
2. Untar the ZServer distribution in the root Zope directory.
3. Test that it works by running start.py in the ZServer directory.
4. Follow the directions in the message linked-to above.

Well, try something like:

<!--#in lastInsert-->
	<li>The id last inserted is <!--#var new_id-->
<!--#/in-->

where lastInsert is your SQL method

Note this is untested code, so caveat emptor :)

Are the #sqltags documented somewhere? I couldn't find them in the DTML

I found some examples of their use, but nothing definative.

I have no problems reading the source and documenting what I find, I just

Specifically I'd like to know about #sqlgroup and friends.

Do you really need this? You can put more than one sql commands in a sql
method, you just have to put a <!--#var sql_delimiter --> between them.
You can insert in the two tables with just one method. The
last_insert_id() should be in the values field of the second insert.
Take a look at the code genereated by the sql wizard in the contrib
page.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <36EEE8E7.11F8DBC@erols.com>

Right now my biggest obstacle to setting up a Zope-powered
site could be finding a hosting provider I have confidence
in who is willing to run Zope.  When I asked my first-choice
provider about running Zope, they replied:

> Though it's true that we can install programs that need root
> instlall, it only so when the program is low CPU/mem use and
> non-intrusive. Zope is neither, so to run it you would need to get
> your own dedicated server through us.

A dedicated server is not a viable option for this site at
this point in time.  So, a few questions:

1)  Are the provider's fears justified?  What sort of
    memory footprint, CPU requirements (for a site that
    should have fairly low traffic at first), and other
    impact are Zope likely to have on a hosting provider?

2)  Would anyone care to let me know what their experience
    has been with the two hosting providers (NexusWeb and
    CodeIt Computing) listed as known to host Zope-based
    sites?  (I've been sufficiently badly burned in the past
    by bad hosting providers that I cannot justify signing
    up for a provider without positive recommendations or
    multiple alternatives for backup.)

Hey Paulo, thanks for that tip.  I didn't know about #var sql_delimiter 
and the ability to put more than one sql commands in a sql method.  I 
had wondered about it but the #var sql_delimiter was the key.  With this 
information, no I don't need to insert into the REQUEST object.  But I'm 
still curious <g>.

Unfortunately, putting last_insert_id() directly into the values of the 
second insert did not work.  It works from mysql command line.

<!--#var sql_delimiter -->
INSERT INTO entry_tbl 
	(master_id,submitted_by,staff_id,version,comment)
	VALUES (LAST_INSERT_ID(),
		<!--#sqlvar entry_tbl.submitted_by type=int -->,
		<!--#sqlvar master_tbl.entered_by type=int -->,
		<!--#sqlvar entry_tbl.version type=string optional-->,
		<!--#sqlvar master_tbl.comment type=string optional-->)

It surprised me that it didn't work as I thought it would get sent enmass 
to mysql for processing so I had thought that the DA wouldn't interfer 
with it.

Subject: [Zope] newbie -  permissions on FAQ object
Message-ID: <199903170144.SAA26992@stout.atd.ucar.edu>

I'm trying to configure a ZOPE FAQ object on starship.python.net .

This is Zope v10.10.2 with ZServer 1.0b2 .

I'm baffled by the permissions scheme.  I've created a FAQ under my
ZOPE home:
http://starship.python.net:9673/crew/vanandel

I'd like selected users to add FAQ entries, but only certain trusted 
users to be able to create categories.

Unfortunately, anyone can add a new category, which is not what I want.
The Security Screen for vanandel/NumPy only enables 'view' for 
anonymous, but still an 'anonymous' user can enter the 'Add a category' 
screen, without being challenged.
There are specific permissions shown for various "add-ins" 
like TinyTables on the Security screen,
but not for the FAQ module.  (I'd expect to see permissions for 
FAQAddCategory.)

Also, when I first create a 'FAQ', I can't view it until I create
a 'isCategory' property.  This seems like a bug, since 'isFAQ' is 
already created for me.

A minor question.  I'd obviously like to test ZOPE with various users,
to see what ZOPE allows them to do.  ZOPE uses cookies to give someone 
permission, after they've supplied a password.
Under Unix, I can manually remove a cookie by editing ~/.netscape/cookies.  How do I do this under NT?  Are Netscape cookies in the registry (I hope not!).

Thanks much for your help.

Excellent.

We here at DC (well, I'm out of the office this week, but I'm there
virtualy) have been kicking around an LDAP authentication mechanism,
probably a folderoid, to go against LDAP.  In fact, this was supposed to
be one of my projects when I get back next week.  From the details below
it looks like you have thought this out well, I didn't even consider
making an API of methods like XSQL methods, good idea!

Under the catagory 'result caching' you might want to consider making some
kind of Connection Manager in your LDAP Connection.  A model I've been
kicking around is a CM class that manages Connections and uses a simple 
caching algoritm.  Wrapping all of the API in a class will also help yu 
when you want to break out the LDAP stuff and stick it in shared.  In
this way, it becomes a sort of 'Device Driver' (to use Ken's
terminology) for the entire Zope system.  We're going to be doing this
with the IMAP functionality that NotMail uses.  I'm assuming what
you call an LDAP connection is like a Database Adapter is to ZSQL methods.
Maybe you might want to consider calling these LDAP Adapters.

The etcUserFolder product has a settable property to change the 'default

Don't hurt yourself.  It looks like you got this down pretty good, I'll
proablby be looking into incorporating much of this if not all into Zope,
want to be in charge of zope LDAP?  We can give you an area on the site.

Subject: [Zope] recursive document oddity
Message-ID: <Pine.LNX.4.05.9903170107540.673-100000@web.spyderlab.com>

Hey zope freaks:

Okay, I am driving myself crazy, maybe I am just doing something silly
(hopefully).

I am trying to write this recursive SQL result DTML (basically a tree):

<!--#in listCategories-->
  <p>Category <!--#var nm-->
  <blockquote>
  <!--#var recurseCategories-->
  </blockquote>
<!--#/in-->

I have a variable pwd that I want to pass along to recurseCategories..

I tried something like <!--#var recurseCategories(pwd=catID)--> (and in
quotes)

pwd is used in listCategories to get a list of categories in that 'path'

A couple questions:

1. Should I be using a DTML method or a DTML document for something like
this?

2. As I recurse will I lose access to documents in my current folder? I
got a traceback to seemed to indicate that once I was into a certain
depth I couldn't access listCategories.

3. Is there a more Zope-happy way to do this?

Does fsdir parameter of fsimport specify the remote directory (where
Zope is) or local directory (from where I look at Zope)?

OK, so it still does not work for me. If someone on this conference
would look at my mail from Monday, I would be grateful. The idea of
having to put all my images into Zope by hand makes me very sick :-)

Check out the article in Linuxworld:
This is good for ZOPE newbees who wonder what and
why about Python (The underlying language of ZOPE).

http://www.linuxworld.com/linuxworld/expo/lw-python.html

Title: "Python, anyone? "

You may have dismissed Python as just another scripting language beginning
with 'P,' but more and more open source developers are finding Python has
some bite

Summary

At first, the Python scripting language may sound like another version of
Perl, but Robert Richardson highlights the differences that make it useful
in its own right. (1,500 words) By Robert Richardson

Probly I misunderstod your problem.

Anyways I want to say that my suggestion does just what 'select
last_insert_id()' does. namely return the number created in an
auto_increment field during your last insert

Hi,

	I just saw an interesting thread over at
http://www.scripting.com. Here's the direct link to the
article:
http://discuss.userland.com/msgReader$4124

Someone wrote a comparison of Zope and Frontier. Followed up by a
technology demo of getting the two to talk via XML.

Interesting stuff.

My profound apologies.  "select <field_name> from <table_name>  
where <field_name> IS NULL"  does indeed return the same value as 
last_insert_id().  My apologies again.

Hi All,

I'm just uploaded a new Product to the contrib area.

It is a poll product based on Amos's example. It uses PIL to draw
piecharts of the poll results.

I was originally going to include a precompiled PIL with the product, but
the
product swelled to 500k as a result, so instead I've left pointers to where
to get PIL in the product documentation.

I'll send a hypertext screenshot immediately after this message so that
people can decide whether or not they want to go to the effort of
downloading and installing PIL.

Pls note that there are some problems I'm having with getting the GIFs to
update appropriately, so after banging my head against a wall for a while
[in true opensource tradition ;) ] I've decided to throw it open to the
floor to see if anyone can find a workaround.

I've also uploaded a 'fixed' version of the Guestbook example product, which
broke going from Zope1.9 -> Zope1.10.

Enjoy!

Andy.

Subject: [Zope] Impact of Zope on hosting provider?
Message-ID: <000701be709e$ea4cd4c0$642fe18d@jharris.coe.memphis.edu>

I contacted NexusWeb yesterday and they said they would provide a setup for
Zope, but no support.  They were not specific as to the setup.  They did
mention they supported Python.  I was going to write them back to see if
they ran Zserver, or just provided the links to Apache.  They did have msql
and mysql.  The minimum plan to support Zope was the 50MB/$20 a month plan.
The other site was out of my price range ($50/mo).

I just started studying Zope yesterday to use for a project I was planning
to use Visual Basic/ADO/ASP for.  I'm testing on a Win95 machine, but plan
to move testing to a Linux box.

I decided before signing up with a hosting server to wait for Zope 2, which
I've seen a couple of references to.  What's the deal on that?  One place
promised a better integrated web server.  If Zope moves more torward being a
totally self contained server, then I don't want to mess with Apache or IIS.

Subject: [Zope] Newbie questions
Message-ID: <D133051DBC4AD111B90800A0C9694983A61695@natasha.auslabs.lucent.com>

Hi Zopesters,

I'm trying out Zope for the purpose of getting a book catalogue on the web.
So far, I'm extremely impressed with it! Of course, I have some questions.
(For the record, I am running Zope 1.10.2 with Apache 1.3.something on a
MkLinux DR3 box, administered with IE4 on NT).

1. When you edit a DTML document using the Zope management interface and hit
the update button, Zope goes away and tries to parse it to ensure that it's
consistent DTML. If this fails, you are left with no option but the
browser's back button, which, under IE4 anyway, seems to discard the changes
you made to the document. Is there a fix or workaround (besides ctrl-A
ctrl-C before clicking the update button) for this? Us newbies write lots of
bad DTML :)

2. When a folder acquires an index_html document from further up in the
heirarchy, the <!--#var title--> tag refers to the title of the index_html
document, rather than the folder being displayed. How do you write the
index_html document to display the title of the acquired object, rather than
the index_html document itself? (Hope this is clear)

3. Finally, I need some advice about how best to lay out the website.
Basically I'm trying to build a site containing a book catalogue. Here's
what I've got so far:

+ Root
	+ Titles [folder]
		- index_html
		+ OriginSpecies [folder, title: "Origin of the Species",
desc: "blah",
				author: "CharlesDarwin", year: 1854]
			- cover [image]
		+ DiamondAge [folder, title: "The Diamond Age", desc:
"blab",
				author: "NealStephenson", year: 1995]
			- cover [image]
		...
	+ Authors [folder]
		- index_html
		+ CharlesDarwin [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]
		+ NealStephenson [folder, title: "Charles Darwin", bio:
"..."]
			- photo [image]

Hope the notation is clear enough. What I want to do is "link" the titles to
their authors and vice versa. So the index_html document for Authors would
display the author, their picture, bio, and a list of titles by them. A
similar arrangement would apply for Titles.

The author property of the title (*) links the title to author, but what's
the best way to link backwards? Similarly, what's the best way to display
the author's information for a title?

All advice appreciated! Thanks.

(*) assuming only one author for now

Subject: [Zope] Newbie install help needed !!!!!
Message-ID: <199903172113.QAA02057@mail.howard.k12.md.us>

Thus far my attempts to install the Zope binary release on a Linux 
machine have been for nothing.  The Install documentation and the Install 
program contradict each other at almost every turn.

The docs say use ./install -u <userid>

but the -u switch is gives a error message, saying it is a invalid switch 
and not supported at all. The install --help, says nothing about a -u 
switch.

The docs say you can specify the cgi directory, with the -c switch, but 
the install program says that is a unsupported feature.

The -s switch in the docs says this is to provide the superuser login and 
password to the install routine, yet the install program say this is used 
to strip tables (perhaps parsing the access file), none of the docs say 
anything more.

I have tried numerous variations, all to no avail.  Perhaps the ZDP 
should have started at the beginning, with usable install instructions, 
instead of with a FAQ.

I must say that the screen shots in the PDF file and those docs are quite 
nice, but thats about it.  Reading the PDF docs, just makes me want to 
get in and try Zope even more.

Is there anyone that could help or give me some pointers ?

Message-ID: <199903180035.QAA28795@christopherrobin.kolo.net>

There seems to be a problem with DTML documents which 
uses more than one <!--#tree--> .. <!--/#tree--> sections.  I'm
seeing a python error when attempting to expand any node of 
the second tree.  I'm going to try and fix this on my own as
a way to familiarize myself with Zope internals but I thought
others on this list might want to be aware of the problem and/or
provide information about their own experience with multiple
trees.

It's on the list. I was originally going to write a simple LDAP auth
object, then thought about it a bit more and realised a generic interface
into LDAP would be more useful, then I can bolt the auth on top.

The way I figure it, I'll support this first. If/when someone needs 
something else, I'll look at supporting that.

Not quite sure what you're getting at here :)

Hm. The LDAP connection already is a class. It's as much a device driver
as the current Database Adaptors.

Good point. Next version, they'll be called that. (I figure I'm allowed
to make changes like this between versions 0.1 and 0.2 :)

That and maybe allowing a mapping for any organizationalRole that 
the users have. More useful for the "lecturer", "student" type
roles.

I've got variable interpolation _mostly_ working. For some reason, though,
it doesn't pick up all the namespaces - I'm probably just not using 
the document templates right. I'm going to add DTML interp. to both the
filters and to the baseDN.

Depends on my supply of round tuits - I might get the pluggable brains
also working shortly. I kinda see how they work now.

Hm - depends if it's easier to get to than my current web site. :)

Some of our applications hang in about 10% when they run. We trussed

Python/thread_cthread.h seems to mention a problem with the Solaris

Hi Thomas,

>Is there anyone that could help or give me some pointers ?


Yup, those switch options are confusing so I avoid them ;-)

First, the most helpful tool for me in working with Linux is
"git".  This is a nice character based navigation and file
management utility.  Just type git.  It came on my RH Linux
and is installed automatically without your request.  This
program is alot like the DOS Norton Commander that
I started using years ago.

So you get the distribution:
  Zope-1_10_2-linux2-x86.tgz
I use git's F6 key to rename it zope1102.tgz
to ease the long typing.
Move it to a newly created directory (F7)
named perhaps "zope". 

Then in that directory, type: 
    tar -xvzf  zope1102.tgz
A new directory is then created under your
new zope directory named:
  Zope-1_10_2-linux2-x86.tgz/
Go into this directory and type

***This is were you got stuck***

./install

***No switches!!!

Then edit the access file now in
this directory and change the obscure
username and password to your favorites
with F4 key to use "vi"  Press  i to 
insert new user/passwrd -- example:
  zope:gogo
Press escape then :wq  to save.

Then 
  ./start 
to start zope
and maybe later if you EVER want
to stop zope (who would ever WANT
to stop!, 
  ./stop.

BTW,  if you want to test the integrity
of the downloaded zope distro, only change
the t to an x as in:
    tar -xvzf  zope1102.tgz

Enjoy!!!

Ok, unstuck, whoops, stuck again.

I guess I have to do this in little baby steps.  Some sort of initiation 
ritual, I think. ;-)  Now I am getting the error message below even 
though python is clearly in the bin directory under the Zope install 
directory.

"./install: bin/python: No such file or directory"

This is the shell install script:


***
#!/bin/sh

# Get script dir
if [ -n "`echo $0|sed -e 's%[^/]%%'`" ]; then
  PYTHONHOME=`echo $0 | sed -e 's%/[a-z.]*$%%'`
  cd $PYTHONHOME
else
  PYTHONHOME=.
fi

export PYTHONHOME
bin/python inst/product_install.py $*
***

A little different than the PERL I am used to seeing, but I've managed to 
make heads-and-tails of the thing.


- I checked the location of python in the Zope install dir, ok.
- I checked to ensure that the sh shell was in the bin/ dir, ok.


Next up, re-upload the Zope file and check for a corrupted archive.


Any other ideas ?

Hope you don't mind me butting in, but if you just want to check out Zope
very quickly, run the Windows version on 95/98/NT.  It was nothing to
install, and I was playing with Zope two minutes after downloading it.
Python is also a snap to insall on Windows.

Hi.  Here's the required History:
Cold Fusion almost then found PHP3
and now ZOPE.

I am running a P100 RH5.2 Apache 1.3,
Kernel 2.0.36 and I am pretty sure I have
Zope running:

http://memes.org

But neither my guru or I can get Apache
to dance with Zope -- I am having all
kinds of problems getting the admin page
to work with me and my Login/PW is just
not taking.

My guru cannot even get it going and
suggests using the Python server -- but
I shall not be dashed -- any more info
you need, I will give you a wee bit more:

Want to use MySQL and will be developing
a Writer's site -- for my fun and no profit,
currently at: http://coelaboration.com --
I want to publish Hyperfiction and Hypertext
using Zope as opposed to Perl or flatstatic...

Subject: [Zope] Parsing XML into/out of the database
Message-ID: <199903182236.WAA24270@cheviot.ncl.ac.uk>

Hi all,

I have an application that consists of 140+ XML documents, roughly 100k
bytes each that I want to be able to query (using XSL pattern matching at
present) and output to XML/HTML and RTF format. This will happen in real
time (if at all possible).

At the moment, my XML documents are held as files in a real file system
(sacrilige! :). However, I'd like to get them into the database structure if
at all possible, as I imagine it will make things easier in terms of
searching. For example, the XML file

<?xml version="1.0"?>
<document title="Cell Biology">
<topic title="introduction" id="cb1">
    Cell Biology is a good thing. If it weren't for Cell Biology, you
    wouldn't be around.
</topic>
<topic title="lectures" id="cb2">
    <topic title="lecture" id="cb2" num="1">
    This is lecture 1.
    </topic>
<topic title="lecture" id="cb3" num="2">
    This is lecture 2.
</topic>
<topic title="reading list" id="cb4">
    <topic title="bok" id="cb5">
        A big bok
    </topic>
</topic>
</topic>

Would lend itself to creation in the Zope database really easily (I think).
XML elements (document, topic) and attributes such as id (used to uniquely
identify an element) and title would be properties of the DTML
document/method. So long as the id numbers were properly arranged, it should
be *relatively* (good word that!) simple to recreate the original XML
document. I assume that parsing the XML (in actual fact, the DTML doc/method
would consist of *very little* XML I think, it all being taken care of in
properties) to create HTML would be, again, relatively easy (my own tendency
is to use the 'title' attribute as a class identifier for cascading style
sheets).

My question is, do people think that this idea could fly? I have spent *a
long time* looking at how to get our Word (sorry for saying that!) documents
into a format that means they can be easily put into a database and thereby
benefit from all the good things that means. Several cul-de-sacs and wasted
weekends later, it seems to me that Zope is coming out to be the closest
thing to a solution for my problem...

(I know from off-list discussions that there's a definite 'weirdness' about
how people have been wanting/needing to implement things and then finding
that (a) Zope does it already, (b) there's a product available or (c)
someones working on it... !).

any thoughts, as usual, greatly appreciated.

Message-ID: <Pine.LNX.3.96.990318144553.4537B-100000@taos.kavi.com>

I've been messing around with using direct traveral on the ZSQL methods.
I'm having a problem getting the traveral to work with anything more than
one level of depth, eg:

http://zope.kavi.com/mem/2/comp_admin/contacts/

Where 'mem' is the ZSQL query (that takes one arg), and the arg is '2'.
But it does work in this case:

http://zope.kavi.com/comp_admin/contacts/mem/2/

Is this a restriction on the use of ZSQL direct traveral, or am I doing
something wrong.

If this is a restriction on how you can use direct traversal, I was
wondering why, and if it'd be possible to 'fix' this. If so, I'm willing
to do it and supply a patch, I assume this is functionality comes from
Zope/lib/python/Shared/DC/ZRDB/DA.py, either in the DA.__call__ or in the 
Traverse object. I'll have to mess around with it a bit to figure out
exactely whats going on (but I figured I'd ask about it first).

This is more or less what I did for my original FAQ product (but on a much
smaller scale). I found out XML docs map nicely onto Zope's DB structure.
I think you should give it a try because really it is not much effort to
implement.

Since the FAQ development has moved to zdp.zope.org my site is no longer
needed so I created a guest account with the following authentication
info:

guest
bobo

at URL http://www.gaaros.com:9673

You can visit it and see my approach to the problem. I should also include
the code of the external method that creates the Zope objects. (I believe
a couple of more zopistas asked me for source access so here is your
chance.) I have backed up Zope's DB so you can mess around as much as you
want.

Without seeing your folder hierarchy, I'm not quite sure what's going on.
Frankly, my head feels like it's going to explode when I try and figure
out how your second example even worked. What are comp_admin and contacts?
Folders? Where do they fit in your folder hierarchy?

I have an event calendar, in which I use direct traversal of a ZSQL Method
to display a particular event. My hierarchy is as follows:

+ events [Folder]
  - event_details_html [DTML Method]
  - dbFindEventById [ZSQL Method]

My dbFindEventById method takes on parameter, event_id. To use direct
traversal on my dbFindEventById query, using the event_details_html file
to display the details of the event with event_id of 2 requires the
following URL:

  http://localhost/events/dbFindEventById/event_id/2/event_details_html

At first, I tried:

  http://localhost/events/dbFindEventById/2/event_details_html

which looks very close to your first example, and it did not work. Then I
realized you are required to specify the name of the parameter in the URL
as well, so I added event_id before the 2, and I was off to the races.

I'm sure I've misunderstood your problem somewhere, and if I did, I
apologize for spouting off nonsense. But, I figured this just might help,
since I got tripped up when I first tried to use direct traversal, also.
Better safe than sorry. :^)

Ok, a bit more info...

mem 		ZSQL method (on top level - stands for member company)
+ comp_admin  	folder (company admin)
  + contacts	folder (contact info for that company)

contacts has an index_html which uses information returned from the mem
query (its not how I use it, it won't even display with just #var).

'mem' takes one argument: comp_id (of which 2 is a test case)

Actually, I've found the reverse to be true. When I try:

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

I get this error:

Invalid integer value for comp_id 

Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module
  File lib/python/ZPublisher/Publish.py, line 413, in publish

    (Object: comp_id)
ValueError: (see above)

If I use creosote.spew to output the comp_id value before calling the
query (I made spew an external method on the top level, this has come in
very handy), the value resolves to 'comp_id'.

But when I don't use the comp_id arg (like in the original example, and
spew shows the value to be 2), it works fine as long as the method using
it is the next on the URL.

Actually you are close, but in your example you use it as I said it works.
In your code app can you do something like this (fictional change of your
example):

http://localhost/events/dbFindEventById/ 
	event_id/2/modify_event/edit_event_details_html

(should be all one line)

Make more sense now?

BTW, thanks for the help. :)

Ok, I think I figured out why we have different (opposite) results in
this. I don't think you checked the "Allow direct traversal" checkbox on
the advanced management page for the ZSQL method. If I unchecked it, then
I could traverse like so...

http://zope.kavi.com/mem/comp_id/2/comp_admin/contacts/

After checking it, I could traverse in this way...

http://zope.kavi.com/mem/2/comp_admin/contacts/

Strange... :)

Still doesn't address my original problem thought. I still can't get
access to any of the results of the 'mem/2' query anywhere other than
directly after it (on the url). 

Ie. 

http://zope.kavi.com/mem/2/comp_admin/contacts/index_html 

Doesn't work, but...

http://zope.kavi.com/mem/2/test_html 

Does... 

I'm still digging through the ZSQL code looking for a way to fix this.
I'll let everyone know once I've figured it out.

Ok, here's a thought. What about trying:

  http://zope.kavi.com/comp_admin/contacts/mem/2/index_html

Since the 'mem' ZSQL Method is in your root folder, it will be acquired
by all folders below the root folder. Thus, the URL above should tell
ZPublisher to go to the /comp_admin/contacts folder, then call the
acquired 'mem' ZSQL method, with 2 as an argument, and using index_html to
display the results. (Assuming the parameter name is not required, because
you have checked 'Allow direct traversal', as you described.)

I am curious to know what the 'Allow direct traversal' button does on the
Advanced tab. Can anyone else here comment on that? Frankly, I didn't know
it existed, as I've been able to use direct traversal just fine without
it. It's curious to me that it changes the behavior of the traversal in
the manner you demonstrated. I'm dying to know why. :^)

In this case, I would probably do:

Hey folks,
Boy I'm feeling mighty dumb, but I just now, after maybe 8 hours of

were printed, I finally saw it in the Trinkets Tutorial which I'm sure I read 
earlier <sigh>.  So just in case someone else is out there in the same

You'll want to check out the doc/WEBSERVER.txt file under your Zope
directory. Make sure your running a recent enough version of Apache
and have mod_rewrite installed. Then, you need to configure rewrite
rules so that Apache will pass authentication info through to Zope.

thanks for the resource - I want to check it out. Maybe you could
answer this for me and other irc newbies, since I cannot find an
answer elsewhere:

All EFNet servers I've tried require me to be running "identd". Is
there one which doesn't ? It's not on my default redhat system and I
won't install it if I don't have to.

Simon,
AFAIK, all the EFNet servers require identd.  If you are running ip-masq 
then you need midentd.  You can find it at rpmfind website 
( http://rpmfind.net/RPM )

Sorry, my mistake, there isn't an rpm for midentd... here's the url
ftp://ftp.ox.compsoc.org.uk/pub/users/steve/midentd/
get the midentd-0.1.1.tar.gz  file

Heck, identd is a trivial enough protocol. You can always just
write one in 2 lines of python which just returns "sod off" as the 
username. :)

That EFnet require it is somewhat puzzling.

Subject: [Zope] Zope install help needed: "Premature end of script header"
Message-ID: <v04011701b3179cd6f425@[204.244.68.39]>

I installed the  Zope binary on a linux box, and everything went well. User
authentication worked successfully with Apache using the 'REMOTE USER'
environment variable. Then I tried to get ZMySQLDA to work, but I couldn't
get the Zope Python install to find 'libmysqlclient'. I got a build of
Python 1.5.1 to successfully import MySQL.

So I decided to reinstall Zope from source, so that I could use my own
Python. The source Zope built okay, but when I tried to start Zope through
the web browser I got an "Internal Server Error" message from Apache, the
error log said I had a "Premature end of script header". I've checked
permission on the var dir and user authentication still seems to work fine.
I couldn't figure out why I was getting the error, so I tried re-installing
the binary distribution of Zope. No luck there either, I get the same
"premature end of script header" error message. I've checked the Zope.cgi
file, and it seems o.k.

Does anyone have any idea why Zope.cgi is failing on me? Is there something
I have to do to Apache or Zope if I've removed the Zope folder and then
untarred and re-installed a new Zope?

Don't know if this'll help, but this is what I get when I run Zope.cgi from
the command line:

Many thanks Pavlos - I saw that the Doc effort had moved to zdp.zope.org and
is using structured text, and thought that it was a bit of an opportunity
lost (no disrespect to the Zope Doc Effort of course) as I was amazed to see
that the FAQ system you wrote was XML-based and hence easily extensible.

Thats excellent! - thanks a lot. I'll be snooping around later on once I get
into work - I had looked at XMLConfig almost straight away, but had to put
it to one side whilst I got to grips with Zope  (and Python!) fundamentals.

At least I've got somewhere to start from now...

again many thanks for this,

Also, and this is important!

Don't forget to make sure that the cgi driectory holding Zope.cgi has
ExecCGI turned on.

As I said this is important, later versions of Apache don't turn it on by
default.

The error you get when running Zope.cgi from the command line is a red
herring, ignore it?

It comes about because SCRIPT_NAME is set by the Web Server and as you
aren't running it through such, you will get errors telling you that various
ENVVARS do not exist.

As to your other problem, hmm, it still sounds as if the var dir is not set
correctly, maybe?

Hi everybody,

I am in a FAQish problem. I am using ZopeHTTPServer for setting up a
complex intranet site. However, access control do not seem to work at
all.

Either I can build a public site (which is viewable by everybody), or
I have to use SuperUser passwd to enter in a private site.

I would like to allow user A to see folder X but not folder Y, and so
on. I have created users, assigned roles, but it seems not to work.

BTW, cut & paste do not seem to work at all.

Any suggestions ?

Thanks.

I'm resending this to the zope list, because I didn't get any response
from the zope-dev list.

Hi.

I have made my first Product (a little message wall that people can post
colored messages to), but I am having some trouble with the Security tab.
When I press the tab, I get a Permissions screen that looks as it should,
but when I click the change button (no matter what permissions I change,
if any), I get the following error:

Sorry, an error occurred.

I don't doubt that I am causing this, but since it isn't occuring in my

Subject: [Zope] frames and external method lookups
Message-ID: <9903190931.ZM14151@saab.coinet.com>

I have a DTML Document that references an External Method. This document
is embedded inside another DTML document. If I view this document, then
the page is rendered correctly. If I now take this document and reference
it from a <frame> tag, Zope complains and says it can't find the external
method. What's different here that causing me problems?

Here's some more details, including the traceback:

1. Zope-1.10.2-linux2-x86
2. The innermost DTML docuemnt (lighttablebar) refers to the extermal method
   like this:
	<!--#in expr="looprange(ltblSize)"-->
   'looprange' is my external method and is located in the top level folder
   'ltblSize' is a property of the document that "includes" this document.
   This innermost DTML docuemnt is also located in the top-level folder.
3. The next DTML document (lighttable_frame) includes the previous document
   with a simple #var command (in between some other html stuff):
	<!--#var lighttablebar-->
   This document has a property named 'ltblSize' defined as 6.
   This document lives two folders down from the top-level folder
   I can use the View tab in the manager to see the rendition of this page
   and it looks just fine and there are no complaints about looprange().
4. If I include the previous DTML document in another DTML document that
   is specifying some frames, e.g.:
	<html>
	<head>
	<title>Stock Book</title>
	</head>
	<frameset rows="60%,40%">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/lighttable_frame" name="ltable_win">
	<frame src="<!--#var server_path
		-->/Stockbook/LightTable/navigate_frame" name="nav_win">
	</frameset>
	</html>
   When I use the View tab to see what this page looks like, I get the two
   frames, but in the lighttable_frame frame, I get an error message about
   looprange being undefined:

So again, what is happening when the DTML doc is being refered to inside a
frame
that is different than not in a frame (and more to the point, how do I get
around this apparent problem)?

Zope (up to 1.10.x) expects every managed object to have a manage_main
method that provides the default management interface for the object.

You need to rename or create an alias from your default management
method to manage_main.

In Zope 1.10, there will be a new inherited method, manage_workspace, 
which should not be overridden, that picks the first item in you
manage_options as the default management interface.  This gives 
you more flexibility in naming and will allow more dynamic view
management.

Oh, I see.  So the manage_main I see is actually being acquired from the
folder my product instance is installed in?  If so that would explain why
adding things to it actually adds things to it's parent folder.

If I write a manage_main method, will it start magically working, or do I
need to add it to __init__.methods and/or one of the __ac_permissions__
tuples?

I apologize if for the off-topic nature of this post, but felt it was
too important to ignore.

Microsoft has released IE5, which is non-compliant with many of the
standards that Microsoft has helped author. As widespread compliance to
standards is one of the things that will greatly enhance Zopes success
in the marketplace (i.e. WebDAV, XML-RPC), I felt that this issue
deserved to be aired here too.

Greetings Webmakers.

The following is a special note from our friend Glenn Davis regarding a

Greetings!
  Since 1993 I've done my best to show everyone the good on the web and
to
help anyone who wanted it gain the knowledge they needed to create that
good.  Today I'm asking for your help.  I'm not asking not as Glenn
Davis,
CTO of Project Cool, and not as Glenn Davis, cofounder of The Web
Standards
Project.  I'm asking as Glenn Davis, a man who, for the past six years
has
worked to make the web a better place for everyone.
   Recently Microsoft released their 5.0 browser and after all this time
there is still not 100% support for the standards that make web
development
easier.  Standards that Microsoft helped create.
  Below are three simple letters.  Very to the point letters that ask
one
very simple question.  I'm hoping that you'll pick just one of those
letters and use it to ask Microsoft the very simple question within.  If
you would copy just one of those letters into an email and send that
email
to wasp@microsoft.com I would very much appreciate it.  This email
address
is one that Microsoft set up for email about standards.  I'm also asking
that you pass this email along to anyone else who has ever tried to make
a
webpage.
  My sincerest thanks for the help you provide.


Sincerely and simply,
Glenn Davis

Subject: [Zope] Web Application Software
Message-ID: <36F2C006.9D7E89C9@amvalue.com>

I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Ahh yes, Glenn "Master of Self-Promotion" Davis has found a cause with
which to attach his persona.  Glenn got his start at InfiNet, our former
majority owner.  I remember when he shared a 10x10 office with the other
Mac person there.

I love the "I'm not asking as Mr. Mega Big-wig, nor as My. Hyper Star,
I'm asking as a humble guy that singlehandedly saved the web" part.
That paragraph is so pathetic, I can't believe he actually wrote it.

IMO opinion, the only cause he is advancing is himself.  It's a shame,
because browser vendors _do_ need to be beaten into standards compliance
and away from bait-and-switch.

Ok, but what do you think of using the three templated emails? I feel
that they're rather well written, and could be effective. After all,

I believe the current agreement that Digital Creations has reached with
Sam Rushing (the author of Medusa) allows for open-source-style
distribution of ZServer so long as it's used with Zope.  Paul can
probably corret the exact legal situation, but basically DC bought an
unlimited license to give it away ... say thank you :-)

OK, I agree, and I ought to just focus on his words rather than on him.
Public retraction on the personal stuff, BUT I absolutely stand behind
taking offense at the words.  If you're going to lead an offensive based
on principal, make the self-aggrandizement a bit more subtle.

Hmm, didn't turn out to be much of a retraction. :^)

We reached a mutually agreeable arrangement whereby Medusa could become
the core for our object publishing system, under the Zope license.
Definately turned out to be a win-win-win (Sam, DC, and Zope).

1) Is it shipped with ZOPE 1.10.2?  (I couldn't find it)

2) Is it purchased from Digital Creations?

AFAIK, ZServer was released (including Medusa) under the same license as
the rest of Zope. Which means that all of it is free software, including
the medusa code it contains.

Nope.

> 2) Is it purchased from Digital Creations?

Yes. At the moment, we are selling Collector. A number of
copies have been sold already. There are a couple of things
to note about a few of the packages that we have been
selling (relatively privately lately):

1) Most have little documentation (read the source Luke :-)

2) Our license specifically reserves the right to give the
software away at some future point (so you need to realize
you are paying to get it now, and shouldn't be annoyed
when/if others get it for free!)

3) Our license specifically prohibits redistribution, or the
creation of derivative works (for distribution)

4) We permit unlimited internal use of the code, including
operating public websites

5) We offer email-based support for 90 days (for 2 contacts
usually)

6) The license is for 5 developers only. If you have more,
you buy more copies

7) Additional support options are available for purchase.

The point of the above isn't to make a lot of money. We're
selling more copies than we anticipated, but hardly enough
to make this our business model. The point of charging is to
cover the inevitable support costs of shipping a product
that has little documentation, but is more technically
advanced to use than the content-oriented Zope general
release.

A secondary benefit is that people who purchase now are
clearly motivated to use the product(s). Therefore, the
support questions tend to be focused around real-world use
of the products, and help us make them more robust for the
inevitable Open Source release (whenever that might be).

So, which products are we currently offering for sale?

1) Collector
2) Z Tables
3) Z Network Client
4) Infoseek DA

In general, pricing is at $1,500 per package. The exception
in the above list is Collector, which is $2,000. The reason?
It makes heavy use of Z Tables, so essentially you are
getting two products for the price on 1.3333 products :-).

Those who wish to discuss this (either to become customers,
or to tell me that we're "off base") should write to me
directly, and _not_ post to the list.

I know that a number of people responded to this already,
including Paul. However, he didn't give as concrete response
as this direct question requests.

The answer is _yes_, Digital Creations most definitely paid
_real money_ to Sam for the right to embed parts of Medusa
in ZServer. However, the intent of the license is to allow
unlimited, free, Open Source(tm) use, within the Zope
environment. If you don't intend to use Zope, then you
should be licensing Medusa separately from Sam Rushing. We
highly recommend it (obviously), and have put our money
where our mouth is.

The reason that this is an important question to answer is
that we are so committed to the Open Source movement, that
not only do we release stuff that we wrote, but when
appropriate, we will invest hard cash to further the
community as well (ZServer being but one example).

<btrieve>
If you can make btrieve a data source you are home free. All you need is the
connector/drivers.

http://www.zope.org/Download/Adapters

Also look into:

http://www.python.org/download/Contributed.html#Database

Typically these modules make there way into zope as they are existing python
modules.
Actually I would gather that Btrieve has a c interface that would make a
great product.

</btrieve>

<dev>

As with all projects .... it depends.

Using attributes is the key to zope. If you take advantage of its ability to
store session variables Zope is far better than other solutions because you
do not need a database to store info during a transaction, you can simply
write it to an attribute in zope thus lowering the # database calls.

I guess the implementation depends on allot of variables that were not
listed in your email.

1. # of concurrent users
2. # of queries and "How databasy is the application? Big Queries?
OnChange?"
3. Specifics on your data model
4. # of tasks required
5. How OO(Object Oriented) are you?

It is a difficult concept to cover but developmental access to ZOPE is
remote by nature. Anything you can do in Zope is accessible anywhere, by
anyone else. Except for installing modules and products, you do not need
machine access ---> Everything is done online and inside of Zope. It is
convenient that way.

Look into the bug collector for the ZOPE site. It allows many levels of
access to the bug database except there is not database just Ztables. It
might be just the ticket.
http://www.zope.org/Collector

Also take a look at the example folder here 
http://www.zope.org/Download/Contrib
Specifically the DTML EXAMPLE FOLDER --> IT WILL GIVE YOU LOTS O' CODE and
HINTS 
</dev>

Just think in OO and Zope will work.

Best of luck.

I wonder just how robust Zope is.

I am writing an internal application for a tour operator that I work
for.  Right now, I'm considering the software for a group quote program
that will allow people on the Intranet or people travelling abroad with
the groups to add or edit services on a complete group package.  

The kicker is that we need to access some btrieve files that are part of
another accounting package that needs to be tied into this.  

Assuming I figure a way around the btrieve packages, is Zope robust
enough to handle an application like this?  All I've seen so far are
shopping cart programs, but this would be much more complex.

Are there any references to any pointers or any such information about
just what Zope can do?  I haven't been able to glean as much as I wanted
from the site.

Subject: [Zope] Why do I have to reimport External Methods ?
Message-ID: <99032019551700.01550@alpha>

Hi all !


I am new to Zope, and I have a problem with External Methods.

Everytime I change the implementation of my file in Extensions/test.py I have
to reimport the External Method to see the changes.

What am I doing wrong ? I just want the changes I made to the source
code to be reflected when I reload a page !

I hope someone can explain what I am doing wrong here.

Maik Röder


Some more details:

I have a folder called

VMBI

and an external method

test

in it. Everything works just fine,  the

index_html

file has a call to the external method, which just prints "Hello World!"

 <!--#var test-->

So the following URL

http://localhost:9673/VMBI/test

prints

Hello World !

But when I change the original source code to print for example

Hello Zope !

Then upon reloading the web page 

http://localhost:9673/VMBI/test

there still is printed

Hello World !

What's going on here ?

You don't have to delete and recreate an External Method each time you
change it's file. But you do have to go back to its properties page and
hit the "Edit" button to reload its module (this is actually a nice
feature of python, being able to reload modules at run time).

> What am I doing wrong ? I just want the changes I made to the source

Well, it may be possible to stat the External Methods file each time its
used, and reload it if its changed (you'd have to store its last
modification time somewhere to compare against). This probably isn't done
for performance reasons. Perhaps it could be linked to the BOBO_DEBUG_MODE
environmental variable or something to address this issue.

Is there a similar way to reload code for a Product, or is the
shutdown/restart of Zope necessary?

If I do have to continue the shutdown/restart process, is there any way of
tuning PCGI so that it loads up faster?

Thanks.

But wouldn't that kill the Zope process instead of having it shut itself

A simple way that works for me is, when debugging, have a normal cgi version
postfixed with -c and use that.  This brings me to another thing:  the default
zope distribution doesn't include ZCGI and friends, I assume because Zope
users supposedly have no interest in normal cgi.  I think it should be
included anyway, so that Full Zope is a superset of Only ZP/ZT.  That's more
intuitive, and then you don't have to download both if you want to use both :)
And ZCGI.py is only a small text file, after all.  And perhaps zope users are
interested in ZCGI after all, or does zope make assumptions about running
persistently (can't see how it could, without violating http's statelessness).

And as far as tuning pcgi: you could shorten pcgi_socket():delay
or the 2 second sleep() at the end of pcgiStartProc().  The first one could
probably be pretty safely shortened with the miniscule cost of a chance of a
few extra connect() calls, but the second one should probably stay the same,
although I'm not clear on its purpose (give time for the child to sort itself
out?).

Here's a random question: how come the win32 pcgiConnect uses CONNDELAY
(defined in pcgi.h as 1), while the unix version says int delay=1; ?

See, that's the problem with open source: all sorts of grubby randoms can go
rooting through your code :)

You may season to taste.  The 2 second pause seemed safe enough 
on most tested systems, since we're flying blind.  We've reserved
an extra header byte to designate out-of-band data that could be 
much smarter about how to handle this, eventually.

I don't have the code here, but it's probably trying to
avoid some problem that I encountered when it was 
missing <wink>.

Probably historical flotsam.  The win32 portion of pcgi is
almost a completely separate product and only coexists with
its Unix cousin by virtue of an overabundance of #ifdef 
clauses. 

I've mentioned this before, but it probably won't hurt to 
repeat.  I don't think the win32 version of pcgi as the best 
solution for this sort of thing.  It's mainly there to fill 
out a niche.  Process launch is more expensive under Windows 
than Unix, so the Medusa/ZServer approach is probably more 
sensible in that environment, where good performance is
desired.

Message-ID: <199903221343.IAA17544@gem.lightlink.com>

As a demonstration project to try and get a client to go with Zope, 
I'm converting a newsfeed database that I had originally built using 
Perl.

The object of the game is to pull fresh articles from a Reuters 
server every two hours and put them in a bin. A human editor goes 
through the bin, culls and sorts the articles, edits where 
appropriate.

One article may appear in more than one section of the site. For 
example, an article titled "Zope Is Cool" might appear in the 
Python, Web Development, and Open Source sections. Each 
section has its own contents page.

This is where I get confused. My Perl application simply used the 
filesystem as a database, and generated three separate static 
copies of "Zope Is Cool", placing one in each of  three directories: 
/python, /web_development, and /open_source. I suspect there are 
much better ways to do it in Zope, but how do I organize things?

My naive idea is to make each article a Document, one of whose 
properties is a list (or dictionary) of categories in which it should be 
placed. Generating each section's contents page would then take 
some figuring out, and performance on doing the contents page 
would be a concern.

If there's a better way, I'd certainly appreciate hearing about it.

Subject: [Zope] AW: [Zope] one 'document' in many 'folders'
Message-ID: <01E40461E003D21195CC0080296495D80B12E6@gates.cdc-group.com>

Correct me if I'm wrong, but the only way I see to do this *inside*
the Zope application is to keep all your articles inside one folder
(pool) and have key documents in your tree structure which 
reference an article in the pool.

I don't know if problems appear when you establish an acyclic
directed graph structure in the object hierarchy itself (I asked
the question myself months ago without an answer).
I see no point why it shouldn't work, but it is not maintained 
by the application.

An interesting fact is that your object's properties vary when
accessed by different paths due to the acquisition structure.
An object inside Zope's database (again, correct me, if...)
doesn't know about its father. It only knows about its sons,
the aq_parent path is constructed on each access.

Would also like to hear more about this...

Check out the FAQ on http://zdp.zope.org  it has some information on how
to use the built-in searching capabilities :-)  It's not perfect, and
needs lots more work, but it's a start.

This application sounds similar to stuff that I (and others on this list are
trying to accomplish).

My immediate term solution is to make multiple copies of the article in the
ZDB. I agree that this is suboptimal.

Paul@DC has mentioned that they are working on a "Catalog" feature that they
would like to integrate with Zope. This feature will be *perfect* for this
application (and many others). Unfortunately, I don't think this is on the
very near term radar scope.

Depending on how far out Catalog is, and when I manage to finish off the
basic necessities for my sites, I was thinking of delving into Zope's btree
stuff and trying to put together some kind of search interface. Right now,
though, I've still got a bunch of work to do before I get to that point.

What a great mailing list! I posted my question, shovelled the 
driveway (Ithaca NY, 8" of heavy wet snow last night), had 
breakfast and an extra cup of coffee, then came back to my desk 
to find 2 good answers. Thanks Stefan and Kevin.

Well, on the one hand I'm pleased to hear that my question wasn't 
trivial. But I'm disappointed to hear that my problem is difficult.

I'm competing against Cold Fusion here, and the problem resolves 
itself pretty easily with linked tables. (At least until I actually try to 
write the code.) So maybe I should just co-opt the competition and 
use ZSQL? But the odb is so nice, I really want to make it work 
that way.

I don't really need for the URLs to look like a directory structure:
instead of /open_source/zopeiscool, it would be okay for the article 
URL to be /zopeiscool?section=open_source. But that still leaves 
the problem of generating a contents page for each section. I 
suppose I could have a script that periodically-or-on-demand walks 
through the articles and generates a fresh static contents page for 
each section. Seems kind of non-zopish, but that might be the 
best way to get decent rendering performance on the contents 
page anyway. (The site is very active.)

>an acyclic directed graph structure in the object hierarchy itself

Yow!

I suggest you try out your idea first. It sounds simple and
straightforward and performance won't be a problem unless you have too
many entries (but I am only guessing).

> placed. Generating each section's contents page would then take 
> some figuring out,

Assuming you have a folder Entries and folders Python and Zope. An entry
in the entries folder is a DTML doc with a lines property named sections
containing the sections (folder names) where the given entry belongs to.
In the root folder you have a DTML method like: (untested)

<H1><!--# var title--> contents:</H1>
<!--# with "_.namespace(section_title=_['title']"-->
<!--# in Entries-->
<!--# if "section_title in sections"-->
... Do something (ie link to the entry or render the entry etc ...
<!--# /if-->
<!--# /in-->
<!--# /with-->

you can call this method from inside the index_html method in each
section's folder.

This is great, I'm planning on doing exactly this myself. 

Roughly, if I don't want sluggish performance, what would the upper limit
be in regard to number of articles? Are we talking hundreds of articles?
Thousands?

Sorry to post a commercial plug here, but it seems in stride
with my post from this weekend to another question
(Collector).

Basically, Z Tables would be a pretty perfect fit (IMHO). I
realize that you too realize that (sort of), because you
suggested going the ZSQL route. Clearly, there are
similarities. But, Z Tables has already been independently
benchmarked as _kicking a**_ performance-wise, and is also
more closely aligned with the gestalt that you indicated you
liked about the object database.

Just a thought (and a few bucks, of course :-).

Hi Phil,
Sorry I didn't make things clear (maybe I'll update the list?).  Yes I 
solved my problem and feel really dumb.  I didn't realize that the 
traceback is in the error page as a comment.  Once I found that out, I 
saw immediately that the arguments passed in had a couple of extra 
fields that I didn't use (the master and detail tables share some initial 
fields).  I took them out of the sql statement and the form, but I didn't 
remove them from the argument list.  (Just an FYI, the system allows 
you to add additional detail records, the first one is autogenerated from 
the master)

Can the denizens of this group enlighten me about what the 
advantages of Python are, versus Perl? "python" is more likely
to pass unharmed through your spelling checker than "perl".

Unless you do something tricky, I doubt you will be able to get normal
search engines to work with a Zope site, since I belive that most search
engines want to read HTML files from the filesystem for indexing.

>Now I wonder - is there a builtin feature in zope that can fix my problem, or

Right now there is a simple Find mechanism, but it isn't really a robust
search facility. In addition, Zope now includes low-level Python packages
for indexing. So the basic tools are there, but there isn't an easy to use,
out of the box search engine in Zope.

We're working on a much better solution to this problem. We're calling it
Zope Cataloging, and it is currently built with ZTables. I believe that
like ZTables, Zope Cataloging will eventually be free, and become a core
part of Zope. Unfortunately, I do not have a timeline. Sorry. :-(

As long as it's you (i.e. important cause of Zope's open sourcing)
posting commercial plugs on zope@zope.org, I doubt many people would
mind. :)

[ZTables]

Although I'm still a complete ZTables newbie, I've seen ZTables come up
repeatedly when there are similar design problems. This would indeed
seem to indicate ZTables are a good fit. :)

[Apologies if this post is considered off-topic on this list]

You might want to try Webinator, an outstanding search engine available at:

http://www.thunderstone.com/webinator/

It's free to use for up to 10,000 documents. It works by fetching documents
over HTTP (not your file system), so it should work with Zope. However, the
free version requires an Internet connection to check with the license
server, so it might be impractical for an intranet soluition without full
Internet access.


Hope That Helps,

/J

I agree :-). Of course, this is precisely why we intend to
release it (eventually) as Open Source(tm). We truly feel
that the community will benefit, so we will release it. In
the meantime, we're swamped, and prioritizing workload based
on hard currency makes for simple decisions...

I just thought a little more about the approach having a pool
and some proxy objects that refer to the pool.

I think it could be made quite neat when using just the 
following code for the proxies (DTML documents):

    <!--#var "RESPONSE.redirect ('/pool/'+id())"-->

So you just need to put zope_is_cool inside your pool
and add DTML documents with the above code under
the same id to your folder structure wherever you like.
Just check it out.

Two caveats: 
- You have to use DTML documents, not methods, otherwise
  id() refers to the folder's id
- Make sure that zope_is_cool really exists inside your
  pool, or you get an infinite redirection!
  (zope_is_cool is not found in the pool and then sought for
  along the aquisiton path, which refers to zope_is_cool itself,
  which redirects to the pool which ...)

Maybe this could be even generalized to some kind of
"symbolic link" product. Ideas anyone?

An alternate solution could be something like <!--#var "_.getattr(pool,
id)"--> for your "link" methods. I think this would take better advantage of
acquisition. A document could pick up its headers and footers from the
category, instead of the pool. It does seem like someone could create a
"symlink" product pretty easily.

Subject: [Zope] Trying to understand the Scheduler
Message-ID: <36F69DC5.2FBB044@eq.uc.pt>

Zope is great. It's so great that I guess I'm trying to use it for doing
something different from what zope it's expected to do. I want to make
some SQL scripts to access different databases and collect the data in a
new table. That I can do with the following external method that calls
see_data and put_data ZSQLMethods

def get_data(self):
    result = self.see_data()
    self.put_data(value=result._data[0][1])
    return None  

Then I wish to make this kind of data management automatic every hour. I
dug in the sources and I found out the Scheduler class, which I think is
what I need (is it?). But I'm having some trouble using it. This was the
external method I tried (without success).

def eventGetData(self):
    rev = RegularEvent(get_data,(),interval=60)
    self.schedule(rev)
    return(None)      

It seems that RegularEvent is not available. Besides, is schedule
available trough acquisition in the folder? 

Can someone give me some light on this. I don't even know if it's
possible to use the Scheduler with external methods so it would be great
at least to know I'm in the right path.

Thanks

Message-ID: <000a01be749d$3ceb65a0$0201a8c0@hawkeye.bob.oc>

Looking for some enlightenment:
<set learning on>

I understand that Ztables was formerly Tabula an
object database.  

If one were starting from scratch without legacy data
would it make sense to use an object database instead
of a relational database?  

If so, is ZTables/Tabula a full, robust database
system that can scale up and exceed the
features of Oracle or SQLxxx databases?

What are the pros/cons of Object vs
Relational databases.

Currently it appears that Ztables/Tabula
is priced at $1,500 but eventually may become
open source.

From recent posts on the list

*"Make site searchable"
*"one 'document' in many 'folders'"

It seems like Ztables would be an Ideal 
solution to these problems.  ie, rather
than the kludge of multiple copies
of the SAME document, ONE copy in
the database.  Also, searching by
key or full text would be possible.

But for further enlightenment, can anyone
point to good examples on the web of the 
use of ZTables/Tabula?

woops, your request to <set learning off>

Do not try to understand the scheduler.  It's not really implemented
nor is it useful for anything at this time.

By nature anything named "tabula" wouldn't be a pure object database :-)
OODB don't have tables, tables are a relational concept, and I believe
ZTables is a relational database last I checked---b ut then I've never
seen it either, but the implications by Jim/Paul/et. al. are that it is
something along these lines.

Maybe, it all depends on your data, the interdependencies, and what kind
of queries you run, how ad-hoc, and what level of reporting tools you
need.  OODB are mature, but their supporting structure (reporting tools,
modeling tools, and more importantly Zen :-) are quite lacking in my
opinion).

i doubt it, but then, Oracle/et al are not necessarily the right answer
for all problem sets, it's not a one hammer fits all nails solution.

> What are the pros/cons of Object vs
> Relational databases.

Dear gods, there's thousands of papers written on this topic ;-)
References are faster in OODB, ad-hoc is easier in RDB, and there are a
billion other blends... it's also necessasry to understand network
databases in my mind before you approach OODB.

You just can't generalize to this level, it's impossible, and a "quick"
overview of OODB v. Relational would require about 30 pages :-)

Subject: [Zope] passings vars to sql method
Message-ID: <36F6C357.1F277AE3@GestaltTechnology.com>

Zopists,

    I run into a problem. I have a DTML Methos that call an SQL Method.
The SQL method, displayTasks, has two parameters, userID and statusID.

The DTML method does have access to the variables userID and statusID
prior to calling the sql method with a <!--#in--> tag.

The DTML method looks like this:

<!--#var standard_html_header-->
<H2> <!--#var document_title--></H2>
<P><b><!--#in getUsers--><!--#var name--><!--#/in--></b></P>
List of tasks: <form action=displayUser method=post>

<SELECT NAME=statusID>
<!--#in listStatus-->
<OPTION VALUE=<!--#var statusID-->><!--#var keyword-->
<!--#/in-->
</SELECTED>
<input type=hidden name=userID value=<!--#var userID-->>
</form>
<table>
<!--#in displayTasks-->
<tr><td><!--#var taskID--></td><td><!--#var description--></td><!--#var
priority--><td><!--#var </td></tr>
<!--#/in-->
</table>
<!--#var standard_html_footer-->



THE SQL methos look like this:
select *
from task_schedule where
task_schedule.userID = <!--#sqlvar userID type=string--> AND
task_schedule.statusID = <!--#sqlvar statusID type=int-->

--------------------------------------------------
I basically can't run the query because it cannot get a value for userID
or statusID.
How do I pass these vars to the sql method from a dtml method???

Thanks in advance,

Freddy, did you make the variables you are passing to your SQL method
parameters of the SQL method?  If not they won't be looked up in the
request, they will only be searched via acquisition.

This is described in the Z SQL guide where it shows the order of lookup
for SQL method parameters.

Have fun!

I'm still experimenting with ZOPE and the FAQ tool, which uses the 
'tree' display widget.  When I add a category or a FAQ entry, these 
items seem to appear in reverse order of the order I added them.

The FAQ widget index_html DTML contains the line:
<!--#tree sort=isCategory-->

On what basis are the categories sorted?  By name of the object's 
folder?  Is there anyway to get the entries sorted in the order they 
were entered?

Thanks much!

Hi all!

I'm having a problem with running queries containing long numbers.
I found in db.py that the data type NUMBER is converted to an
integer which overflows in my case.

The errors:

from
                if scale==0: type='i'
to
                if scale==0: type='f'

in order to force a float type, but this has no effect, it seems.

I'm sure that I'm misunderstanding something here.
Any pointers to where I can look to fix this would be greatly
appreciated.

Without having yet looked at the source(*) could this be an error
occuring in Oracle itself?

I just noticed the ORA-* which is typically an Oracle error message.

  I have no problems with other applications as long as I stick with
 floats. Notably, Zope on Windows running through ODBC has no
 problems--the values are all converted to python L types. (Hey! maybe
 I should take a look at the ODBC code...) This is what originally led
 me to believe that the problem wasn't with Oracle, but within the OCI
 interface to Zope.  
  I also thought that it also might have something to do with my Linux
 install, but SQL*Net doesn't have problems and Zope works wonderfully
 except for long numbers.

 Environment info:
 Zope 1.10.2
 ZOracleDA 2.0.0
 RedHat Linux 5.2
 Oracle Net8 Client

Subject: [Zope] Questions about DocumentTemplate.
Message-ID: <004c01be74fe$35088aa0$0801a8c0@bobcat>

Ive started playing with DocTemplate for a project, but I will be
using it sans Zope.  I hope this is still the appropriate
place...

I want DocTemplate to expose an object model, and it seems
perfect for the task.  However, Im having trouble using "."
expressions.

Code speaks louder than words, so my code is:
##
class Spam:
	def eggs(self):
		return "Eggs"

spam=Spam()

from DocumentTemplate import *
ss=HTML('Eggs are <!--#var expr="spam.eggs()"-->')
print ss(spam=spam)

ss=String('Eggs are %(spam.eggs)s')
print ss(spam=spam)
##

What Im hoping to do should be quite obvious - I want to refer to
"spam.eggs" in the DTML.

With the HTML example, #var expr="spam.eggs()" is the best I can
get.  It seems ugly to me, and I feel there must be a better way.

Using the String example, I can't make _anything_ work.

Any I missing something?  Is there something I can do so that
String('Eggs are %(spam.eggs)s') does what I want?

Please CC me - Im not on the list (but did peruse the archives
before mailing...)

Thanks,

Mark.

(<!--#tree--> <!--#var id--> <!--#/tree-->) doesn't work either)

This is using Zope 1.10.2 on linux (2.0.35)

All I get is a blank screen - how come??

Here's an alternative that works:

from DocumentTemplate import HTML
class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()
print s.ss(s)

and a second choice:

from DocumentTemplate import HTML

class Spam:
  def eggs(self):
    return "Eggs"

  ss = HTML('Eggs are <!--#var eggs-->.')

s=Spam()

Thanks for the response.

My problem is that I want a deep object model.  I want the user
to be able to say "spam.eggs" or "pantry.eggs" etc.  Just using
eggs wont do - I really need it qualified.

The solution I came up with was:

class DotWrapper:
	def __init__(self, ob):
		self._obj_ = ob
	def __getattr__(self, attr):
		bits = string.split(attr, '.')
		ob = getattr(self._obj_, bits[0])
		for bit in bits[1:]:
			ob = getattr(ob, bit)
		return ob

Then:
 s=Spam()
 print s.ss(DotWrapper(s))

does pretty-much the right thing...

Thanks,

Mark.

	Small caveat: Since whitespaces could occur in an nested
attrbute
	access ("a.  b  .x") , it's better to string them first. An
alternative 
	approach for DotWrapper's __getattr__ could be (not tested):

	def __getattr__(self, attr):
	    bits = map (string.strip, string.split(attr, '.'))
	    return reduce (getattr, bits, self._obj)

If your search engine works via http it should work OK with Zope. 
Thunderstone Webinator (thunderstone.com) does this, and there's 
a free version that I think will do up to 10,000 docs. (The 
commercial version costs $700.) There's a command-line switch 
that tells Webinator to go ahead & index URLs that include /cgi-
bin/.

We'll look at overhauling the install documentation for the next

Jeff,

I have cc'ed your question to the list, not to defer it, but to let you
pick the brains of several people who have tried, some successful, some
not, to run zope as a user in a web hosting environment.  None of us
here have tried it so we're not really the ones to ask.  It is true
there is no documentation on Zope with web hosting, perhaps your
discussion will provide information for the Zope Documentation Project,
AKA the Martijn Conspiracy.

As I understand it, the web hosting provider you pick is key to the
whole issue.  If they run the kind of environment that works with Zope,
great.  If they don't (and most probably don't by default) you must
communicate to them clearly what you want.  If they are cooperative and
cool, they will oblige you and join our Zope hosting family.  If you
can't get ahold of them and/or they don't care, your out of luck unless
you go with a Zope friendly provider of which there are two to be found
here.:

Hey Sture,
Check to see if your index_html is a DTML Document.  DTML 
Document has its own namespace and doesn't use the folder's.

If you change DTML Document to a DTML Method then you'll pick up 
the folder's files and folders.

My experience has been that if the hosting company is running Apache (many
do) and if they have mod_rewrite installed (which is probably also pretty
common), it is not *too* difficult to get Zope running in that environment.
However, many hosting companies have policies against creating long running
processes. Zope takes up a few MB of memory, which is considerably more than
an instance of Apache... so many providers are not keen on that kind of
thing. Before putting effort into trying to make Zope work in their
environment, you'll probably want to ask them if they are willing to let you
run a process that will hang out in memory all the time.

CodeIt (one of the Zope hosting companies, http://www.codeit.com) will
actually host Zope for you. You don't need to deal with building and
configuring the package at all.

This typr only affects meta-data seen by some Zope tools.

There is a similar change that needs to be made to *work around*
this problem.  In DCOracle/ociCurs.py, change:

            elif dbtype==2: # Number
                if scale:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

to:

            elif dbtype==2: # Number
                if scale or 1:
                    buf=Buffer(arraysize,'d')
                    dbtype=4
                    dbsize=8
                else:
                    buf=Buffer(arraysize,'i')
                    dbtype=3
                    dbsize=4
                f=None

This has the undesirable effect of causing all
numbers to be treated as ints. (This is what oracledb
does) :(  Unfortunately, you can't tell from Oracle column
meta data whether values in a column will fit into Python ints.

The right way to fix this is to implement Oracle's
NUMBER or VARNUM C data types and convert to Python
ints or longs on a case by case basis.

Right, but in this case, it's because DCOracle bound a buffer
that was too small to hold the values.

The <!--#var expr="spam.eggs()"--> is a perfectly valid way to do
it. Another way would be to use the "with" tag:

<!--#with spam-->
  <!--#var eggs-->
<!--#/with-->

Neither is really "more correct" than the other, though the with
construct is probably cleaner in situations where you use many
services of the object:

<!--#with spam-->
  <!--#var eggs-->
  <!--#var method_one-->
  <!--#var method_two-->
  <!--#var method_three-->
<!--#/with-->

Hmm - it appears that the expr support is currently broken
for the python string format syntax. We'll take a look at
that. You can, however, also use the with construct here too:

ss=String('eggs are %(with spam)[ %(eggs)s %(with)]')


Just in case you hadn't found them already, the latest DTML manuals
are on the zope site at: http://www.zope.org/Documentation/Guides/DTML.
They contain some examples that try to demonstrate common DTML idioms.

First, you should use branches_expr, instead of branches. And second, it
depends on what type of DTML object you have this code in. Is this code in
a DTML Method or a DTML Document? If it is a Document, you'll have to
specify the Folder you want the tree to start at::

<!--#tree expr="PARENTS[0]" branches_expr="objectValues(['Folder', 'File'])"-->
  <!--#var id-->
<!--#/tree-->

I think that your approach would work and have the drawbacks you suggest.
You could try it and see if performance is actually a problem.

Here are some other ideas.

First, you can put an object in many folders without creating
multiple copies.  You can't do this from DTML, but you *can*
do it from Python, and therefore, from an external method. 
This may be the simplest approach.

Second, you could come up with some sort of document management
system, based on clever indexing machinery, like ZTables or
on relational databases.  As someone else mentioned, Zope cataloging
with use ZTables to provide collections with advanced searching and
organizaing features.  This is still a work in progress, however.

You're wrong. ;)  There are a numnber of ways to solve this.  I suspect
the simplest is to simply put the same object in multiple folders.

(BTW, this is essentially the same thing as using Unix hard links.)

Sorry you didn't get an answer.  There is no problem with creating 
acyclic or cyclic graph constructors in the, uh, object hierarchy, 
which BTW, need not be a hierarchy. :)

Yes, exactly.  In fact, a better name for aq_parent might

Hello!

   I've finished large project using pure CGI concept (I used Neale's
html.py). Now I (and my boss) are thinking of switching to Zope, or at
least ZTemplates.

   While playing with Zope and SQL (I am using Postgres, hence ZPygres
Database Adapter), I found that Zope, when loaded into memory by Zope.cgi
(I am using Apache, and need to use in the future) opens a database
connection for every Folder where I created Connection object.
   It is bad, as I have many databases, so Zope eats up memory. Another
problem - what would do Zope if I restart Postgres (so all current
connections break)? Would Zope reestablish connections or just report
error?
   How could I limit number of connections Zope opens? How could I
define a timeout, after which Zope close a connection if there is no
activity between Zope and Postgres? and reestablish connection when
application ask for SQL data?

   With ZTemplates and CGI all these questions has one easy (but not so
nice) answer - there is no constant connection, a connection established on
every CGI invocation.

PS. BTW, I wrote short introduction to Zope in Russian:

   Any Russian here to verify my understanding of Zope?

As I understand it, you should just create one Connection object in your 
root folder.  Then all the folders underneath the root folder have access 
to that same Connection object.

Ahh, no need.  Just put one Database Connection object in the top folder
and all the subfolders will "acquire" it.  That is, any SQL Method
defined lower down can use it.

It should re-establish the connection.  If it doesn't then there's a
bug.  This works fine with all the Database Adapters I've used.

There is one connection per Database Connection object.

Hmm, this is quite a hard thing to do, unfortunately.

Of course this means the CPU gets a tremendous beating on every request
and the response time goes down.

   There are connections to different databases. So you said "one
connection to one database"?

   I'll retest, but currently, when I ask ZPygresDA to close connection,
Zope reports "the site has technical difficulties" when I'm trying to
access the application.

Not too long ago I experimented a little with cyclic structures
inside Zope's database. One thing I noticed was, that the copy
support failed with tracebacks like this:

Traceback (innermost last):
  File D:\Programme\zope\koelnzope\lib\python\ZPublisher\Publish.py,
line 877, in publish_module

  File D:\Programme\zope\koelnzope\lib\python\BoboPOS\SimpleDB.py, line
958, in exportoid
ExportError: Object 184337 references itself

This led me to the conclusion to better leave my hands
off non-hierarchic data structures which differ from those
created by the management interface itself.

	>> Would also like to hear more about this...
	> Like what? :)

More or less simple answers like "this is ok and this
is not", or "you can store any complex Python data
structure inside the DB, but in conjunction with the
management interface, you get the following drawbacks.."

I'm still a quite unclear about the object management
in the database itself and the management layer Zope
adds. 
But maybe I just have to read the docs harder ;-)

If you can use one connection string in Postgres to access multiple
databases, then you just need one Database Connection.  Otherwise,
you'll need one connection per database.  Note that I don't mean per
table -- I don't know much about Postgres and don't know if it organizes
tables into separate databases that are selected with a "use database"
command.

Right, which is the correct behavior, as you had disconnected from the
database.  I thought your question was about restarting _Zope_, so I had
a misunderstanding.

I don't know anything about the Postgres client library and whether it
can reconnect to a server when the server is shutdown.  This definately
isn't a Zope issue though -- the client should handle it.

   No. Connection string include database name, so I need one connection
for every database.

   I meant 3 different situations:

1. I started Potsgres, then started Zope, then restarted Zope - Zope
reestablished connections. It's Ok.

2. I started Potsgres, then started Zope, then restarted Postgres. Zope
does not reestablish connections: This site is currently experiencing
technical difficulties...

3. I started Potsgres, then started Zope, then went to management screen
and explicitly close a connection. Zope does not reestablish connections.

   Situations 2 an3 could be resolved, if I go to management screes, close
and reopen database connections. But it is hard to remember "always restart
Zope if you restart Postgres"...

I'll admit that cyclic data structures are pretty rare, 
so handling them may not be totally correct in every case.

Export of objects partcipating in cycles is potentially, 
uh, confusing, unless the cycles are with objects that are totally
contained within the object being exported, although containment
is pretty hard to check.  I should probably take this error check out.

OK, but I need to know what "this" is.  I don't think
you want me to enumerate all possible "this"s. ;)

> structure inside the DB,

You can store any complex Python data in the DB subject to:

  - It must be picklable,

  - It must follow the persistence rules:
 
    - Root objects must be "persistent" meaning
      they subclass BoboPOS.Persistent (or implement
      an undocumented interface that BoboPOS.Persistent
      implements, sigh)

    - Subobjects of persistent objects must be "persistent" or
      they must be immutable, or be used immutably, as in:

         def add_member(self, member):
	      members=self.members

              # Oops, mutated a list
              members.append(member)

	      # OK, so pretend it's new and readd it
              self.members=members
         

> but in conjunction with the
> management interface, you get the following drawbacks.."

Basically, the objects need to implement certain
interfaces if they want to play in the management system.
If they don't want to play, they have alot of freedom.

We need to do a much better job of documenting these interfaces.
 
> I'm still a quite unclear about the object management
> in the database itself

The object management at the database level tries to be as 
transparent as possible.  The wish is that you don't have to
think about it.  Basically, if you follow the rules above, 
you should be OK.  

Probably the biggest pitfall in the database is the inability
to get to database objects when their classes can no longer be 
imported, because classes or modules have been moved or deleted
or because errors have been introducted into the module source.
We need to figure out ways to make these problems easier to
diagnose.

Ok, so we don't have a problem here :-)

I agree that if a remote cause forces a database connection to close, it
should attempt to re-open it... that should be optional of-course, but
should be the default.

> 3. I started Potsgres, then started Zope, then went to management screen

Nope, you closed the connection, you have to open it.  This I agree is
the appropriate way to behave.

   Yes, I think Zope must reopen connection.

   May be...

   Well, what about such situation:

4. I started Potsgres, then started Zope, then worked with my application
and Postgres failed (postgres fails sometimes). Postgres returned an error
and closed connection. Zope, I think, should reopen the connection back,
but will it?

Well, actually it should be the job of the DA, not Zope.  It's not
spelled out in a standard anywhere, which probably should be solved.
More documentation probably :/  But hey, someone's gotta know what the
DA is really supposed to do, other than looking at an existing one.

Don't honestly know if it WILL, but it seems reasonable that it should
be capable of trying at the very least.  Again, this is the
responsibility fo the DA, not Zope... that should be made clear.  You're
using a 3rd party DA, so you might want to talk to them about it as
well.

So class Persistent's __setattr__ is basically also the level

Can I expect the undo support to work if I take care of the

Pedro - 
If you need to do periodic tasks, the wisdom of the list says go with a
cron job script attaching to your Zopesite via the ZClient interfaces
(caveat: I know nothing about this - just repeating what I've read here)
Anyone know were to look for info on this elusive ZClient stuff?

Read the source luke :-)  

Actually here's where to find the basics of what you're interested in...

	.../lib/python/ZPublisher/Client.py

This should probably go into the FAQ in the ZDP PDQ ;-)  I remember
seeing a few examples of it, for the the life of me, I can't find them!

Subject: [Zope] Using database-connection from external methods
Message-ID: <19990323200153.C251@RaVER.duck.org>

Hi!

This will hopefulle be my last questions in a while...

Is there some way I can reach/use ZMySQL connection method from within an
external method? Rephrase - I have a connection established within Zope - I
want to call an external method that handles some sql-queries - is this
possible, or should I still have the external method handle it's own
connection?

Can external methods set/send back variables to the calling document/method?

Another question while I'm at it - is the DateTime module in 1.10.2 broke in
some way? (I get an error if I try to make a new property with the date type
set)

Help is much appreciated

The next release of Zope will have a 'utilities' directory
in the distribution that has a load_site.py utility that 
demonstrates use of ZClient (aka ZPublisher.Client).

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

After reading Jim's mail I turned myself to the cron. I had already
written a simple script to http-call a DTMLDocument that calls my
external method. It works, but now that you told me about ZClient I see
I could have saved some time with just a single command

ZClient.py [-u username:password] url [name=value ...]

Thanks guys

Connection strings for MySQL also require you to include the database, but
you can still change databases at runtime via the 'use <database>'
command.

Subject: [Zope] Zope Database in XML
Message-ID: <36F7EF09.6AD34A99@digicool.com>

A side project of mine is to allow conversion to and from
Zope databases (and export files) and XML.  This will allow
people to more easily access their data without Zope and correct
problems, such as moved or renamed software modules, that prevent
data from being unpicklable.

I've completed a first cut at a tool for converting a Zope 
database to XML format. It is provided in the file 'bbb.py'
in a 'utilities' directory that will be included in the 
distribution directory of the next Zope release.

If you want to get this now, you can get it via Zope
public CVS access.  See 
http://www.zope.org/Community/Services/CVS_public_access
for details.

To run the tool, use:

  python utilities/bbb.py -rxml var/Data.bbb

For now, the tool provides a way to "get at"
your data without Zope and get a bit more of an idea
of how Zope organizes data in the database.

The file uses a module 'ppml.py' (Python
pickle markup language :) that must by in the
same directory as bbb.py or in the Python path.
ppml.py provides for conversion from Python pickles
to XML.  It will eventually provide conversion
from XML to Python pickles.  Comments from members
of the XML SIG (those who happen to spend time here
too) would be welcome.  I haven't written a formal DTD
for this XML format.  I would like to use a standard Python
XML pickle format, but I'm not sure if such a thing exists 
yet.

I took the approach of conversion to and from Python pickle
format for two reasons:

  - It allows me to do conversion to and from
    database format without actually creating any 
    (application objects).  This is much faster than
    creating actual objects and does not require that
    any application Python modules needed to unpickle 
    objects be around or working.  For example, this allows
    conversion of objects that are not unpicklable.

  - It means that many of the implementation details
    of pickling can be avoided.

Of course, in combination with the Python pickle modules, 
pickling objects to XML is straightforward:

  import pickle, ppml
  print ppml.ToXMLloads(pickle.dumps(myobject))

Enjoy.

Jim

Just have your external method call ZSQLMethods. For instance, I have an
external method which allows the user to upload a file to the database.
The external method reads the file, parses it, and calls a ZSQLMethod to
update the database.

To do this, assuming your ZSQLMethod is in the acquisition heirarchy,
simply call it like you would any other method. If you have a ZSQLMethod
called 'insert_client', which takes the arguments 'name, company, email',
just call it...

self.insert_client(name=client_name,company=company_name,email=client_email)

 
> Can external methods set/send back variables to the calling document/method?

External methods can modify the current REQUEST object that the DTML uses
from name resolution. If you are calling the external method from within
the DTML, just use 'self.REQUEST' to access the current REQUEST object.
Just create/set items on it like it was a dictionary... 

sekf.REQUEST['new_key'] = new_value

If you can access the database directly through this interface(xml/pickle),
couldn't you *potentially* map a network drive to the interface(cifs/nfs).
This could allow you to render data in and out of the database through the
file system interface rather than ftp/http.

Alternatively your external method can return objects to the calling DTML.
for an external method spammethod you could do omething like:

class A:
	pass


def spammethod(self,n):
	a=[]
	for i in range(n):
		tmp=A()
		tmp.no=i
		a.append(tmp)
	return a

Then in your DTML you can do something like

<!--# in "spammethod(20)" sort=no -->
<!--# var no -->
<!--#/in-->

Ugh.  I thought I had checked it in, but I handn't.
I just checked it in.  Try a cvs update.

I'm not sure what you are getting at here.  You can export and import data to
a file system now, using the Zope database format, which is built on
Python's pickle format.  The XML conversion feature just gets the data into a
slightly more editable form.

One key difference between http/ftp and the file system is that
Zope trusts the file system much more and is willing to get pickles
(binary, XML, whatever) from it.  This is a sort of a security 
feature.  In the future, I'd like to make a variation on the
Python pickler that was easier to configure to be pickier and
safer to use with network supplied pickles.

Ok, I figured out a way to hack around this limitation of traversing an
ZSQLMethod. I whipped up a simple 'pluggable brain' for the ZSQLMethod in
question...

---------------------------------------------------
from Acquisition import Implicit
from Record import Record

class req_store_brain(Implicit):
    """ stores info from sql query in REQUEST """

    def __init__(self):
        new = {}
        for key in self.__record_schema__.keys():
            new[key] = getattr(self,key)
        self.aq_parent.REQUEST.other.update(new)
----------------------------------------------------

This simply sticks the results of the ZSQLMethod in the REQUEST object.
Everything in the heirarchy after this has access to the queries results.

What I am referring to is rendering objects in the ZOPE database to a file
system view. The object database could be managed as a Network Drive(except
that the view would be data in the ZOPE object database). You could through
some translation (xml or other) render the object database to CIFS/NFS.

1. Run applications directly from the ZOPE file system.
2. Modify and Render objects through a regular file explorer or file manager
potentially an external text editor or file editor(word,excel,other).
3. Objects that had no meaning to the file system view would not be
rendered. Attributes to file properties.

This is a feature of 8i that oracle is pushing. The rendering of a database
to a user that does not realize it is a database.

ie.
1. Open a spreadsheet in the Network Drive and see a current version of a
file and its data.
2. Intranet is now a shared drive - depending on your privileges - you see
different objects.

I guess what I am asking is: Can Zope act like a CIFS/NFS file
system(virtual file system) with a layer of translation for converting Zope
Objects to File system objects directly (XML or other)?

If I understand it, this is how the database is rendering objects to HTTP or
now(Zserver)FTP. Why can't you render them as a Network file system?

Any thought?

I've just hit something similar in the mysql client. The mysql client
has a time-out to close the connection with the server. I'm using it in
a test environment where it isn't accessed frequently. The connection is
automatically closed and I have to manually close and open the database
connection.

Has anyone already fixed it? Excuse me if it has already been asked in
the list, but the egroups site isn't working.

You seem to be asking for a hybrid of Zope and Samba ;-)  Seriously, we
have Samba, so one answer would be a filesystem driver for the undelying
OS that talks to the Zope server to get its information. This could be
re-exported as a samba share, or NFS or AFS or Coda or what-have-you. 
I've been musing about it for linux for a little bit - I'm going to try
and convince one of the bright sparks around here to take a crack at it.
For NT hosted Zope, you'd need to write an equivalent filesystem driver
- apparently the the SDK for that is ~$1000.

Oh, and parts of this are already present in the ZServer - it talks FTP,
and there was some discussion of exposing object properties as virtual
docs of some sort. Check the list archives.

Ah.  I think that this is one of the things that WebDAV is going to
accomplish.  For example, IE5 can create an thing that looks like 
that looks like a Windows explorer on a Zope folder.

Ahhhh....

Oracle's approach to this is an add-on to 8i called IFS(Internet File
System). It renders a database to http(woo...woo, Zope does this in its
native functionality). Although, they are working on a renderer for native
file systems. This would enable object methods for making files on the fly.

As Zope already accomplishes this(rendering objects), thus presenting the
view of the oo database is thus a filter. HTTP,FTP,CIFS,NFS,POP,IMAP all are
protocols that speak the requesting clients language. Make Zope the engine
and supply a framework in Zserver to plug in the server renderer.

Samba is a great example. It renders between file systems quite well,
although it is rather a tough and complex animal and very specialized.
Although it would work along the same lines.

Actually, there is a PERL module to simulate file systems already. It could
be good start. Considering that most file viewing on Windows is moving to
HTML, the Network Drive is looking more and more like a simple security
login with a connection that is persistent, rather than actually mapping the
drive.

A distributed (native-CIFS/NFS) file system would change the industry.
Actually it already has (http) through a browser window. I am wondering when
it will occur as seamlessly as not having to be in a browser. If an ORB
existed that could render data to the requesting protocol, it would be a
great product, I think ZOPE could do this through the ZServer architecture.

The Server in this case is the renderer, the ORB is the fulfillment
component and the OO Database is the storage mechanism. The protocol plug-in
is stored in Zserver and renders the appropriate view of the data.

 PROTOCOL |    SERVER    |   ORB   |  OO DATABASE  |

</OS ADD-ON CLIENT> 
   HTTP   |    ZSERVER   |    --- ZOPE ---         |     Client dependencies
   FTP    |    ZSERVER   |    --- ZOPE ---         |     Applications
designed to be client/server!!!

   IMAP   |    ZSERVER   |    --- ZOPE ---         |
   POP    |    ZSERVER   |    --- ZOPE ---         |
</OS ADD-ON CLIENT> 

<OS NATIVE>   
   CIFS   |    ZSERVER   |    --- ZOPE ---         |     No Client
dependencies - Native Applications
   NFS    |    ZSERVER   |    --- ZOPE ---         |     CLIENT/SERVER
functionality yet no dependencies!
</OS NATIVE>                                             OS support is the
dependency!

If the rendering engine were modular, ZOPE would always be first in
delivering support for new protocols and client functionality(DAV
Support!!!), without changing the structure of the underlying database. The
data exchange between the ZSERVER AND ZOPE would have to be managed. "You
wouldn't want to serve a POP client an Excel file unless it is an attachment
just as you wouldn't want to render a query to a FILE SYSTEM accept ones
that have been designated as OK." Get It?

It would save the world a little time and effort if one system could render
data to a diverse set of clients. Rather than making a new server every time
a new client arrives. I could simply build a layer of translation(XML) for a
client and BINGO! New client/server.

At the Native OS level this has the most power. Rendering live data into an
Excel file on the fly is a real world application that would be a huge hit
right now. "I want this months sales report... open Sales.xls  BINGO!!! The
data is there." I would really like to edit html in Dreamweaver as I
regularly do and have it render into Zope. If you had file system level
support every known application could be stored inside of Zope or have
access to the data inside of ZOPE.

Here is the interesting one:

If you can have direct file access you could:

Open a client application out of an oo database that rendered a view of the
database back at you.

(Sounds awfully like an OS!!!)

Just Thoughts.....

[Project Idea] Looking ahead to the future of Linux ...

[ I am on the Digest list, so send responses directly if you
  expect an immediate response. ]

Although I am a new user, I am quickly growing very fond of Zope.  Quite
amazing, multiplatform and all.  The option to use either the built-in DB or
an external one, the built-in web server or an external one.  My entire
company is thinking of standardizing on Zope since we run Solaris, Linux and
NT (along with a few, rogue *BSD variants) on our server-end.

Little and big internal projects aside, I was wondering if Zope could
possibly fill a gap that will come about with Linux shortly.  That gap is
software distribution at the enterprise server to client level.

Linux (and many other OpenSource software and systems) is winning in the
server arena, but the corporate desktop world is staying with NT and the
consumer world is staying 95/98.  While the third will take awhile, the
corporate desktop is something that is attainable in the next few years
(with all the Windows 2000 issues which I do not want to get into).
Microsoft has SMS for NT and even Apple has a better system for MacOS X
Server.  What does Linux have?

First off, most Linux distributions have RPM.  While the format is the same,
the filesystem and other distribution or installation-specific configuration
may differ.  Quite possibly, a Zope-based distributed management system
could be built to serve this purpose.

I guess my main question is if anyone else is trying to forge such a project
togther.  E.g., does the Caldera Open Administriative System (COAS) plan to

The field of online software distribution is certainly hot.  Marimba,
the original Java darling, has reinvented themselves in this field:

  http://www.marimba.com/products/products.htm

They are playing, though, in a pretty complicated mission-critical kind
of field.  The requirements are pretty daunting.

One thing I've seen that's pretty interesting in a low-tech kind of way
is rpmfind from rufus.w3.org from a repository.

It's certainly a big deal in that it is an enormous initiative.  Take
some time to jot down what you think the business goals and the
requirements of such a project might be and recruit some volunteers!

Beyond writing an ExternalMethod, is there a good way to catch exceptions?

For example, I have a database application that looks pretty ugly if
someone attempts to add a duplicate key to the database.  Ideally, I'd use
a <!--#try--><!--#/try--> tag to trap exceptions and to provide handlers
for them.

Anyone have any thoughts on this?

Message-ID: <8174B1EE3D2CD21180960000F8056723FCC3CE@telisnt1020.is.tel.co.jp>

 Thanks for the pointer!

 I have to retract what I said in a previous post about not having a
 problem with the ZODBCDA--it has the same problem. I had made a small
 hack of a product for my own study that connected through ODBC and
 that didn't have the problem because I used Python longs. I somehow
 got the two confused...

 This works, but everything gets converted to floats like you said. In
 my case, this is not so much a problem because I use a lot of large
 numbers but doesn't seem practical for general use.
 I found that if, in Buffer.c, I change lines 143 and 144 to

      case 'd':
         return PyLong_FromDouble(self->val.d[ii]);

 I can get the same results as my product--everything is a
 long. Unfortunately, this causes everything to be printed with
 Python's 'L' appended instead of '.0'. Either can be fixed by
 using fmt="%.f" to all of my number fields, but that seems like a 
 lot of extra work (maybe a quick hack to the Z Search Interface
 would do the trick?)

 Plus, what if I really have floats somewhere? Would something like:

      elif dbtype==2: # Number
         if scale:
            buf=Buffer(arraysize,'f')
            dbtype=4
            dbsize=8
         else:
            buf=Buffer(arraysize,'d')
            dbtype=4
            dbsize=8

 in ociCurs.py (lines 123-131) handle this? I haven't tested it yet on
 float fields. It might be better to just leave everything as floats.

I'm not sure I understand what you want here, but perhaps interesting
for you is the Trove project. Perhaps it's directed more to larger scale
internet based distribution, though. Another problem is that as far as I
know the project isn't progressing very quickly if at all (perhaps you
can help).

I've even heard mention of ZTrove, which would be a Zope based Trove, if
I understand well. I don't know what the status on that is.

Mind, I don't know a thing about Trove, just giving pointers in the hope
it's useful.

Trove is sketches of code in Python (written by Eric Raymond) and ZTrove
is vaporware, barely prototyped in bobo a few months ago when I was on
the Trove list.  It's unfortunate, since I felt that Trove was a great
idea; the Internet hasn't reached the point of 'we need it now' in order
to get some development behind it.  Personally, I think Sunsite and
RedHat should give us lots of money so we can write it. :)

With Ken and I now in the Zope loop (Ken was one of the original Trove
designers, and I was in on the GUI side of things, pushing what was at
the time Bobo) we could probably bang something out sometime in the far
future.  We'd prefer someone in the community start it up because Paul
and Rob have us booked sometime into the year 2011.

Confera uses ZTables functions, and these were introduced in Zope 1.10

...just download Zope 1.10.2 and Confera will work just fine.

Confera requires Zope 1.10.2 to run. SearchIndex is a package that is
oncluded in that release.

<!--#var standard_html_header-->
<H2><!--#var document_title--></H2>
<P>
<b>Available Documents:</b><p>
<table border=1>
<!--#with gestalt -->

 </tr>
 <!--#/in-->
<!--#/with--></P>
</table>
<!--#var standard_html_footer-->

The parent object has the following permission settings:
Roles

settings?                 Anonymous      Manager  Sysadmin  User

 no         View                                    yes

no   use SQL methods

the rest are set to acquire .... the role sysadmin is declared in the
gestalt object..

Do you what am I doing wrong?

Subject: [Zope] Counters
Message-ID: <B10C0321620CD2119A4B00805F295A8405DC6F@peter.sths.org>

I remember noticing various comments on the list bemoaning the lack of
some sort of counter. I also remember noticing the objections which were
raised, and why counters weren't feasible. I don't remember reading
these objections, which may be why when I found a need for a counter, I
sat down and wrote one. I now have a working Counter product which
provides a <!--#counter--><!--#/counter--> tag .

It includes the ability to have multiple non-incrementing displays of a
counter, and the optional ability to render the individual digits using
a supplied template, thus allowing graphical counters of whatever sort
you feel like using. The counter uses a long property in the containing
folder, so you can manually set the counter to whatever you want. 

It also provides the optional capacity to have a short 'memory' of
recent IP's, preventing the 'running up' of the counter by scripts or
massive reloading (well, makes it more difficult anyhow). 

The template is supplied with variables which indicate the position of a
given digit in the list (it is wierd, it works from back to front, since
it uses modulus) including whether the particular digit is the first,
etc. 

If someone will supply me with instructions on how to package the
product, and how to upload it, I will be happy to make it available.

Thanks are due to tsarna@endicor.com, on whose product this was based,
and to Jim Fulton and Philip Aylesworth for answering my questions.

Uh, no, I think. chown root /fred, chmod 700 /fred, chmod 711 
/fred/barney. Then anybody can get a listing of barney, but only 
root can see what's in fred. And if I su nobody and run python, 
os.listdir('/fred/barney') works but os.listdir('/fred') gets 'Permission 
Denied'.

With regard to the IP checking mechanism. Realize that this reduces the
count for machines behind a masquerading firewall and increases the
count for machines on dynamic IP dialup accounts. 

If anyone is interested in using this counter but wants to prevent a
given IP from incrementing the counter a second time under any
circumstances, it should not be too hard to modify the code to store the
IPs in an SQL table as (I think) Slashdot does. I have no need for this,
and don't intend to code it, but the code, being Python, is, I think,
clear enough to modify.

I'll indicate my appreciation of your contribution by, well, asking for
more! :^)

One of the big objections of the counter kind of object is that the
object database gets bigger on every request.  A good workaround for
this would be to cache writes to the database.

Thus, imagine a counter that:

1) Only wrote to the database after a threshold had passed.  For
instance, only every tenth state change or not until ten minutes had
elapsed since the last write.

2) If the process was nicely shut down, the object would save itself.

3) Had knobs in the management screen that allowed adjusting the
"buffered write" policy.

The benefits:

1) The database wouldn't keep versioning into oblivion.

2) The application wouldn't be slowed by writes on every request.

The drawbacks:

1) If the process exited not nicely, some state changes would be lost.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC72@peter.sths.org>

In the stock Zope 1.10.2 distro, putting a Long in a property causes a
curious error to manifest. When the property page is displayed, the long
is display like 44353L. If the then change any other property and
attempt to save changes, you get a traceback saying that the property
for the long is invalid. You are forced to manually remove the 'L'
before saving changes. 

May I suggest that when the properties are display, if the type is
'long' then the display code
should do something like this:
str(long_value)[:-1]

This would remove the L before it was ever displayed.... Alternatively,
something in the response code needs to be modified to accept an 'L' at
the end of an integer destined for a property whose type is 'L'.

Message-ID: <19990324200904.8613.rocketmail@web204.mail.yahoo.com>

Previously, using Bobo, I created several PickleDictionaries for use on
my website. Regularly, I would pack these databases before ending the
CGI call since they were altered very frequently.

Now, using Zope, I find that I cannot pack them without receiving error
messages telling me I'm attempting to write while the database is in
read-only mode (it appears the Zope threads out the packing). I also
found that Zope caches these databases and issues an error when I
attempt to open them again.

What is the best way to pack and close these databases? How can I query
which db's have been opened? Even if I do keep a mapping of previously
opened db's, how can I find out if Zope is closing them. 

Any help is appreciated. 

Thanks,
Kevin

Hey.. this isn't bad.. in writing even :)

Okay, I have a prototype of this written.. basically you can do the
following:

<!--#try-->
foo
bnar
<!--#var sgkjgdsjksdg-->

<!--#except-->

The exception was <!--#var err-->

<!--#/try-->

So, if an error occurs inside the first block, the second block is
rendered with err substituted for the variable (in this case it prints
exceptions.KeyError

This is pretty basic stuff, so I'm looking for ideas on where to take
this.

Anyone have more ideas?

This is just a guess, but I doubt it.  You'd probably need a DOS port of
Python, which would eliminate all the networking code.  This is just me,
I don't have a 3.1 box, but... you're welcome to try :-)

I've gotten a lot of reports about a broken link to the ephemeral,
much-referenced "BoboPOS3a1" technical docs.  I promised myself I
wouldn't update the link unless I updated Jim's doc to Zope-ify it.

Thus:

1) The official name of the database is "ZODB", the Z Object Database.

2) The News on the site has a link to the ZODB3 Technical Documentation.
This is a very well written, circa October document from Jim Fulton that
describes the architecture of the next version of the database (i.e.
Zope2).  It's quite nice -- contains UML diagrams, API discussions, etc.

3) The broken links have been updated.

Message-ID: <B10C0321620CD2119A4B00805F295A8405DC79@peter.sths.org>

Ok, having read the newly available ZODB manual, it seems that I should
override __setstate__ and call the old __setstate__, passing it a
dictionary containing only those attributes I wish to be persistent.
Then I don't have to call my __setstate__... it will be called
automatically by the system. This should have the effect of making any
item not mentioned in my dictionary non-persistent, which will allow me
to accomplish Paul's goal. Now, the BIG question... This ZODB manual is
for ZODB3, which we don't yet have! So is this still the correct and
workable technique for accomplishing this?

Thanks again... and please everyone, don't use the old Counter product,
since these tags are going to conflict horribly, and this new product
should be much better for the DB, according to Paul, if I can make it
work.

For .deb there is the official package manager (www.debian.org), but
there's a 'Debian Package Finder', which is already complete python :-)
On http://badger.alaska.net/debian/finder.cgi
That may be easier to convert to Zope.

Well - darn if you aren't right.  Only the
immediate parent directory of the item to
be opened/listed matters (so far as execture
permissions), not the grandparents and up.

Seems strange to me -- but seems you're right.

Maybe something like this for the version 2.3 :-)

<!--#try-->

<!--#except KeyError-->

<!--#except ValueError IndexError-->

Here is the updated Counter Product. This contains two classes, one
which provides a visible Counter Product which can be added as an
object, and which has Security options, and a new tag which provides a
means of accessing the Counter Product. Note: the tag should be able to
access ANY object which possesses a getCount() and a incrementCount(md)
where md==_. So an SQLCounter Product which stores its numbers in an SQL
database should be able to use the same tag structure. Since it passes
md into the incrementCount, the Product is free to store as much or as
little of the REQUEST as it chooses. My product stores only the IP
address, and only under proper conditions.

The tag structure is described in the CounterTag.py source file, and
examples are given.

I hope this is useful to someone.

Okay after I opened my big mouth I had to deliver. :)

NOTE: THIS IS NOT ALPHA ALPHA CODE.. BEWARE

Here's an example of what this is:

<!--#try-->
 This is the try block
 <!--#raise type="bar"-->
  You suck
 <!--#/raise-->
<!--#except-->
 There was an exception! Yay!
 <p>It was <!--#var errname-->
 <p>It has this to say: <!--#var errmsg-->
<!--#/try-->

I incorporated a suggestion that except should handle <!--#except
NameError--> to specify the error to trap.  Also, <!--#except--> will
handle any errors by default.

This is packaged as a product, is this the best way to distribute this??

Grab it from:
ftp://ftp.spyderlab.com:/pub/zope/Try-0.1.0.tar.gz

Since I've only been programming Python on and off, hopefully I didn't
make any major assumptions about doing things a certain way.  Please let
me know if I have.

There is another IRC channel on the EFNET network, #zope.

It is 'protected' by an eggdrop bot so there should be little chance of the
channel disappearing.

It is manned, at the moment at least by, Phil Harris, Fredy Villa and
others.

There is also a knowledge bot, zoppy, which can answer rudimentary questions
about Zope/Apache/Python.

We have a small but growing community, join us.

See ya there

If I have a URL like '/manny/moe/jack', I know that from within the 
top-level object, I can retrieve the object 'jack' as 'manny.moe.jack'.

But if the context is jack, how do I specify the top level so I can 
talk about manny?

I want to use a computed field to convert the broken umlauts from a

But when i test the expression i get the following result:

Does anybody have a solution for my problem?

The top-level object is the 'app' attribute in the Main
module.  Note, however, that this will change in
ZODB3.

  import Main
  Main.app.manny

From an external method, self is the object the Externel Method is called
from. If you have REQUEST passed in, you can access PARENTS[0], which is
the top object. From there you can traverse down the hierarchy.

Subject: [Zope] Configuration of Apache-authenticated Zope on Apache 1.2.6
Message-ID: <Pine.GSO.4.02.9903250839420.15119-100000@isis.visi.com>

Okay, I understand that the "fall-through" authentication to Zope will not
work with rewrite rules when Apache 1.2.6 is used.  Unfortunately the
project I'm starting is being done for a shop that refuses to upgrade to
1.2.6.

I have Zope working just fine with Apache authentication; for the needs of
my project, this method of authentication works just fine.  However, I
need to know how to properly set up Zope to run in a virtual domain
"container", _and_ to only authenticate parts of the object hierarchy at
one time.

The idea is that we have a website

docs.foobar.net

that is a virtual domain on an Apache 1.2.6 server, and we need to
authenticate any requests underneath

docs.foobar.net/manage

so that the world can see the pages but only people in our list can
manage.

Another simultaneous difficulty is finding the proper way to make this
virtual domain automatically start in folder "docs" of Zope's object
hierarchy.  I've used an Alias to translate docs.foobar.net to
docs.foobar.net/cgi-bin/Zope.cgi/docs , and it works fine, but I don't
have proper Zen mystical knowledge of Zope to understand the _proper_ ways
of doing these things, if such ways exist.

I have done a scan of Email archives and most of the documentation on the
Zope site, but either I'm dumb as nails or just don't know the proper
magic keywords to get the information I need.

Zope looks great, I've resisted learning a new language but a killer app
makes it worthwhile.

I am not sure how to classify it. The original complaint was about the
Properties page. 

My problem seems to be with values returned from MySQL - even regular
integers get an L tacked on the end (This didn't happen with zope 1.9).

So is this two seperate collector entries?

Where does mine go - Zope, ZSQL Methods, or ZMySQLDA? What do others
think? Has this shown up with other SQL DBMSes?

One thing I just thought of: I moved my ZMySQLDA over from 1.9 to 1.10.2
without recompiling it. That is when I noticed this problem. Whould
something have  changed in the python header files or something that
would have made it advisable to recompile ZMySQLDA? What did others do?

Phil.

Message-ID: <613145F79272D211914B0020AFF6401907BBB6@gandalf.digicool.com>

Greetings,

For those of you interested in the NotMail project we have some
announcements.

First, Digital Creations has officialy adopted NotMail as one of it's
products.

Second, in an attempt to make the products at least *sound* more mature
:), we are changing the name.

Third, in the last two weeks I have been working pretty hevily on
NotMail and it has changed significantly.

Therefore:

NotMail is, for the interum, called The Artist Formerly Known as NotMail
(TAFKAN).  We still call it NotMail, but that's just our code word.

TAFKAN was once a product, but now it's just a bunch of dtml methods.
The actuall imap functionality that TAFKAN needs has been abstracted
into another product called IMAPAdapter.

IMAPAdapter is very early alpha software.  It has several known bugs,
and Linus knows how many unknown ones.  Your millage may vary.  It may
light your computer on fire.  It might delete all your mail and crash
your imap server.  It might send insults in your general direction.  You
get the point.

IMAPAdapter is, in Zopespeak, a 'user database'.  Other examples of user
databases are User Folder, UserDb Folders, and etcUserFolders.
IMAPAdapter walks, swims, and quacks (to quote Jim) like any other type
of user database.  The simplest example of using IMAPAdapter is:

Create an empty folder without an 'acl_users'

Add an IMAPAdapter (it will automagicly call itself 'acl_users'),
telling it where to find it's imap server, what default roles to assign
to users, and other misc stuff.

Create a DTML Method called index_html containing the following DTML:

    <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

Going to this file will prompt you for a username and password (assuming
you've correctly set the permissions and roles).  The username and
password you enter here must be a valid IMAP login for your imap server.
It is *not* necessary to add a Zope user to Zope, IMAPAdapter will try
your uid:pwd pair against the IMAP server and validate/deny you based on
the sucess or failure of making an IMAP connection.

What you will see when you look at this DTML Method is a pretty #tree
breakdown of all your imap namespaces, folders and subfolders.

IMAPAdapter, like all other user databases, contains a validate() method
that Zope calls to authenticate a user.  This method returns an imapUser
object (which inherits BasicUser, like most other Zope user objects).
This user object is what AUTHENTICATED_USER refers to.  imapUser exposes
the imap API to the DTML programmer.  The API is currently a very rough
draft, and there are several functions that were in TAFKAN that are
missing in IMAPAdapter (like the folder management stuff to
add/edit/delete imap folders)  At the moment, IMAPAdapter is pretty much
read-only on your 'imap space'.

Voila!

IMAPAdapter is available in public CVS.

Web CVS access will be here soon!  (yippee!)

I have a Zope sandbox which I would like to use to play with new features 
as they become available.   Unfortunately, for the past several days my 
sandbox server has been broken because ExtensionClass/ComputedAttribute.c 
is missing.

Is it missing on purpose?  If so, is there  a way I can work around it?

Message-ID: <Pine.LNX.3.96.990325153317.2349F-100000@taos.kavi.com>

Hello,

I'm having a strange problem with logged in users getting to anonymous
areas of the site. Here's an simplified example to explain...

Two directories off the /
/private
/public

/private allows no access to "Anonymous User", requiring a login.

There are no usernames in /acl_users. All the user info for logging into
/private is kept in /private/acl_users. 

/public has no acl_users folder.

If you start up netscape, you can get to /public without any problems. But
once you've logged into /private, you can't get back to /public without
getting an unauthorized error...

  You are not authorized to access this resource. Username and password
  are not correct. 

  Traceback (innermost last):
    File lib/python/ZPublisher/Publish.py, line 877, in publish_module
    File lib/python/ZPublisher/Publish.py, line 531, in publish
      (Info: /MCExam)
    File lib/python/ZPublisher/Publish.py, line 297, in unauthorized
  Unauthorized: (see above)

Any tips about how to fix this. Note that the login info has to stay in
/private/acl_users (they can't be moved to /acl_users).

Thanks,

Ok, the problem was that I had the roles defined on the top level folder
and the users defined in the subfolder. By moving the roles into the
subfolder, the problem went away.

I suspect a matter of resolving.  Probably be a two step procedure, 1) try
to match the error by string exactly, otherwise 2) evaluate each handler 
in turn and see if the exception isa class.

I have fixed this in 0.1.1 of the Product which is now available from the
same directory as the original.  I've also made some other additional
fixes relating to the default error handler.

Here's the file:

Subject: [Zope] URL and #tree trouble...
Message-ID: <19990326081646.A10042@box.dust.za.net>

Hi!

A day or two since last question - now two new ones...

Q1

My site is organized so that one folder keeps several other files and folders (containing files and folders and so on). Something like:

Top [Folder]
	F1 [Folder]
	F2 [Folder]
		F2-file1
		F2-file2
		F2-folder1 [Folder]
		F2-folder2 [Folder]
			F2-folder2-file

...

index_html (Top) has <A HREF="F2">F2</A>
index_html (F2) has <A HREF="F2-folder1">F21</A> and <A HREF="Top">Top</A>

Starting at URL: localhost/Top is fine and following links to F2 and from there on to F2-folder is correct (URL beeing localhost/Tope/F2/F2-folder1), but if I, when in F2, press the link to 'Top' something strange? happens: I get to Top all rigth, but the URL is now localhost/Top/F2/Top (Top beeing appended to the URL)

What am I dooing wrong?

Q2

Recently I got help on using the #tree tag, and apparantly everything worked all rigth, but ...

I get the tree-view, can expand the tree pressing either foldernames or the '+' button - fine. But If I press the '+' button I'm not able top directly access the files appearing (404 error, file not found), I have to enter the folder first before I can get the file. This seems strange and I want to know if theres a solution to this.

Heres my #tree href part:

<A HREF="<!--#var URL1-->/<!--#var id-->"><!--#var id--></A>

Help is much appreciated

You're URL is a relative one. The browser sees 'Top', and requests the
object Top with the current Base URL, which is localhost/Top/F2/. And
because of Aquisition, Top.F2.Top exists.... And so will
Top.F2.Top.F2.Top.F2.... which can get you into a nice caching problem.

Your URL should include the realitve path to the subfolder. the var
tree-item-url gives you the URL to the current object, relative to the base
object.

Your code should read (untested):
<A HREF="<!--#var URL1-->/<!--#var tree-item-url-->"><!--#var id--></A>

Or words to that effect..

Oh good, it's not just me.

I also tried the cvs version last night and was getting the same problem,
Computed attribute is not an includeable library, or something along those
lines 8^).

Hello.

   Continuing the subject...
   Next question. If Zope opens one connection to a database, how does Zope
manage concurrency?
   Currently, when two CGIs run in parallel, every CGI opens its own
connection to the database, lock neccessary tables, and Postgres manage
concurrency very good (even detecting deadlocks). Next Postgres version
(6,5) will have Multi-version Concurrency Control. But all this is for
different sessions. Zope opens only one session. Is it a problem with
concurrency?

Hi,

This is (I think) an unusual question on this thread, but I want to ask it.

We are at the start of making an intranet, which will contain a database of
procedures (how to handle some examinations etc). We want to make it able
that people can query this database and get the information they want on
there web-browser.

A day ago, we were confinced that PostgresSql with PHP3 (www.PHP3.org)
would be the solution to this problem. This on a RedHat Linux 5.2 system
with Apache as
web-server. But now we've seen Zope. I'm wondering..., can Zope do the same
things as PHP3? Or is this a complete different application? How stand Zope
and PHP3 next to each other?

I believe PHP3 is a scripting language... I'm wondering : is Zope also only
a scripting language? Or is it more? Is the scripting language (=Python?)
more powerfull then Zope)

Are there people, using PHP3 next to Zope? 

ps. Has Zope the capability to easely make these scripts? I mean not
text-based , but in a certain IDE or RAD application?

Please, say in some simple words what Zope is and for what it can be
used... I've read the web-page. But since I'm a stupid person in this field
of webservers I can't understand what they are explaining.

Thanks in advance.

Kind regards, Tom.

Subject: [Zope] Limitations of just using External Methods ?
Message-ID: <3.0.5.32.19990326185538.0093de20@mail.skinnyhippo.com>

Hi zoppelgangers,

I have several applications built 100% with python CGI
scripts that I'd like to run on Zope. The reason for 
this are :
a) For the better performance (I was worried about
   the scalability of CGI for high-availability and
   knew I had to move to FastCGI or the equivalent)
b) I really really like the way Zope takes care of
   the CGI variable handling (ie. declaring the 
   HTML form fields as arguments in the python method).

However, I don't really want to use DTML at all.
The reasons is that I find it much harder to read 
than pure Python. This is just a personal aesthetic 
thing and no criticism of Zope at all (full kudos to
Digicool on an excellent application). It's just
coding aesthetic : I like it all kept in Python, 
like servlets in java (as opposed to CFML, ASP etc).

So, I've put all of my CGI scripts in a newly-created
extensions directory and registered them via the 
Zope web-manager. It was, as the documentation says,
incredibly simple and it seems to work for simple
methods. (I'll declare my own packages later).

Now, if I just use External Methods like this (using my
own ex-CGI Python scripts to query databases, IMAP etc),
am I missing out on any of Zope's main benefits ? 
In particular, the cache management ?  
Would I have to turn my stuff into  a Zope Product to 
get these benefits ? (I've not had too much joy with
the Product stuff yet)

Message-ID: <000501be777e$83130900$147800a0@pc-pi0>

Hello,

I'm confused with external methods. Please help.

I want an external method to access its context (for the
purpose of acquisition, etc.). So I write:

def myExtMethod(self):
    pass

Within myExtMethod, I should be able to:
- write self.REQUEST to access the current REQUEST object (I
need to be able to modify the current REQUEST object with
self.REQUEST.set(...))
- or for example self.myzsqlmethod() to call a zsql method object,
right???

Let's suppose that myExtMethod is:

def myExtMethod(self):
    l=[]
    for i in self.l:
        l.append(i+1)
    self.REQUEST.set('l', l)

Now, how can I call this method from DTML?

<!--#var myExtMethod-->
<!--#var "myExtMethod()"-->
<!--#var "myExtMethod(this())"-->

All don't work. I end up in a traceback. "read only class, buffer"

Any hints?

Zope manages concurrency by being single-threaded... so only one query at a
time, on ANY connection...

Hi Jepthe,
First, if you want to acces the REQUEST object, you need 
to declare it as a formal parameter:

def myExtMethod(self, REQUEST): ...

REQUEST is then passed automatically by Zope's internal
magic, which looks up formal parameter names and matches
them to arguments from HTML forms, HTTP Headers, etc.

The "read only class, buffer" traceback is due to a very 
annoying bug in ExternalMethod.py and screws up any 
other error messages in external methods.

I can't remember exactly if it was in line 254 or 256 in
ExternalMethod.py, but here's the code I use to fix it:

ExternalMethod.py, from line 254

                if type(error_type) is type('') and lower(error_type) in
('redirect',):
                    raise error_type, error_value, tb
                if (type(error_value) is type('') and
                    regex.search('[a-zA-Z]>', error_value) > 0):
                    error_message=error_value
                else:
                    error_message=''

With that you should get better error messages.

Regards,
Stefan

PS:
	<!--#var myExtMethod-->
	<!--#var "myExtMethod()"-->
should be both OK

Tom,

There are probably other guys here that can give you a better comparison
between zope and php3. I never used php3 but I used ASP (the microsoft
stuff), which is similar (though worst than php3 :-).

With Zope you get a server markup language (called DTML) which you can
mix with HTML. This concept makes it even easier to program than mixing
a scripting language with HTML like php3 and asp do. From what you said
I guess you will just need this kind of programming... so Zope will be a
better choice than php3.

But with Zope you also get *the best* scripting language available:
Python. You can add logic to your application by writing external
methods or products. This kind of extension is much more powerful than
php3, although maybe a bit more complex.

Zope also has a great IDE for managing your site through the web. 

Although I cannot tell you which one is better, if you give Zope a run
try and, ... if my instinct is correct, you will want no other thing.

hope it helps,

pedro

I've used PHP3 since it was PHP/FI and done lots of work in it. It's 
database integration is excellent and the ability to include PHP3 
code into an HTML document and have it 'executed' is really neat (I 
think CGI's are ugly, whereas code in the delivered doc itself is 
elegant - my opinion, YMMV). I've run PHP on Solaris and Linux, and 
used a lot of the contributed code.

Since I found out about Zope, I've desubscribed myself from the PHP 
lists and been focussing on Zope almost entirely. I posted a message 
a while ago 'Tough Questions about Zope' and got some excellent 
answers, for more details I'd check it out in the archives.

PHP3 is a scripting language, and is relatively easy to get started 
in. I may get a 16-ton weight dropped on me (in joke) but I think 
that if you're used to scripting languages already, you may get your 
application up and running faster in PHP3, as Zope scripting ('DTML') 
requires a bit of a mind-flip.

However, once your application gets more complex, I think you'll find 
that Zope will start to pull ahead of PHP3 and eventually pull very 
far ahead. The list of things that Zope provides 'out-of-the-box', 
which are very difficult to do in PHP3 is pretty long; access 
permissions (at varying levels) at a per-directory and per-'object' 
level, editing of web pages online, *undo* - yes, undo!, and versions 
are the things that come to mind initially. There are many others. 
Obviously, there are some things in PHP3 that are a bit 'unusual' in 
Zope too (setting variables for instance! :)

The scripting language of Zope is Python - I've bought several Python 
books (personal rec: Internet Programming in Python by Watters, van 
Rossum and Ahlstrom - top geezers in the Python world) and have found 
it to be quite a beautiful language. You can't install Python 
programs 'directly' into your DTML document, but 'External Methods' 
seem quite easy to write. Once you become familiar with 'Products' 
and what *they* can do, your jaw *will* drop.

> Are there people, using PHP3 next to Zope?

This is a question I asked. The upshot is that it's pretty difficult 
to do in seemless way with current implementations of Apache (ie more 
or less impossible) but that a later version will do that.


> ps. Has Zope the capability to easely make these scripts? I mean not
> text-based , but in a certain IDE or RAD application?

I would say, yes. I would suggest reading the FAQ, then the 
documentation, reading the documentation again (especially the DTML 
and ZSQL documents), read it once more and then if you do decide to 
try Zope over PHP3, have a go at your application. I think that it's 
highly likely that you will be able to get by with just some DTML and 
a database connection.

I'm not knocking the documentation here - the DigiCool guys (and 
gals?) have relatively recently embraced the open-source concept and 
seem to be doing 10 things at once.

I don't think you're stupid at all! :) There are some new and unusual 
concepts in Zope that many people will not be familiar with 
(particularly if you're coming from a 'traditional' web-publishing 
environment).

If it helps, I've been in contact with several other people, both 
here in the UK and elsewhere who are *extremely* excited about what 
Zope is and what it can do.

> Thanks in advance.
> Kind regards, Tom.

You're welcome - I got a lot of help starting out, just trying to 
pass it along... :)

Maybe It's self.l that causes the error. It's hard to understand what
you want, but I feel it should be

   for i in l

Maybe I can help you with this. The traceback you get is probably the
standard error raise in ExternalMethods. To debug external methods I use
try/except/raise code blocks and when I get an exception I return it to
the screen. Something like this

def mymethod(self):
    try:
	mycode
    except:
	import sys
	return sys.exc_type, sys.exc_value
    
    return something

Not yet. ZServer is multithreaded, but Zope itself isn't. This is because
the BoboPOS (cuurent version 2) doesn't support concurrent access. The all
new ZODB 3 will support this, and then Zope can (will?) become
multithreaded as well.

   So I have some time before I'll see problems with concurrent access to

Ok, I'm dumb.
After some digging, I found that the problem lies in
the expression 'self.l'

'self.' gives access to the object hierarchy, not the variables
namespace.

So, I solved my problem by writing 'self.REQUEST['l']'
instead of 'self.l'

Also, I think that this should be clearly documented.
Apparently, the only way to acess variables namespaces
in external methods is through self.REQUEST
This confuses a 'normal' python user whose variable
namespace is usually accessed through self.

Can someone confirm (or infirm?) this?

I believe that you can just ask for it in your function signature:

def my_method(self,l):
  return l + ' is cool!'

Jephte 

In your external method l is a local variable. You can access it by simply
referencing it. something like

def spammethod:
	l=[]
	for i in [1,2]:
		l.append(i)
	return l

It can do the same thing, and more.  This isn't a hack on PHP3, but Zope
has many more components and widgets out of the box.  It's also object
oriented, which helps when your components scales, or when you want your
application to suddenly be stitched into four other application six
months from now that you didn't forsee.

>Or is this a complete different application? 

PHP has it's niche.  Tony 'tone' McDonald mentioned that he thought code
inside HTML is elegant, and it is, but it's even more elegent when that
code is for the layout of your user interface only.  Mixing application
code with HTML, or worse yet, making your entire HTML document one huge
script, is not so elegent.

Zope is an Application written in a scripting language (Python) that is
based on several components also written in Python and C.  One of the
components of Zope is Document Templates (DTML) which is also a
scripting language.  It's a bit complex, much more so than PHP's
underlying system.  Tony also mentioned that PHPs database itegration is
excellent, and I'd like to add that Zope's is also top notch.  A
particular nice thing about Zope is it's database abstraction layer,
what we call Database Adapters.  You can write program for any SQL
server and just change the DA when you change databases.  Or your app
could use two databases transparently; the DTML programmer wouldn't need
to know which database is being queried, it would just be a case of
calling the write SQL methods.

This also give some compartmentalization.  Your Python expert writes
your external methods, your SQL expert manages DAs and writes ZSQL
Methods, and your DTML/user interface expert uses all of these methods
to layout the application.

Comming soon.  The problem is (rumor has it) that Apache sends Zopes
output directly back to the browser, not giving it a change to run
through any other handlers, like the PHP one.

There is a web based interface.  The (IMO) ultimate programmer interface
is emacs, which can use Zope with FTP (if your using ZServer).

Whew.

Zope is a web application platform.  It is a framework for writing
applications over the web.  It is more than this, because it supports
more protocols than HTTP, but for your purposes you can call it a web
app platform.

Zope provides you with a standard set of services that your application
can build on.  Services include DTML, trasparent persistence of your
data, interface to databases, a management interface for developing and
managing your application, and a whole slew of out of the box objects
for you to use (like documents, files, methods, DAs, mail transport,
etc...)

Many people have mentioned Python in responses to your question.  Python
is an incredible language, but I think the application you described can
be done easily in Zope with no Python at all.  All you need is DTML,
some ZSQL Methods, and a good design and your done.

These 'benefits' you feel you might be missing out on you might not
need.  One of Zope's best features is the fact that you can just use the
components you want.  In fact, it sounds like you may just need
ZPublisher by itself.  If you go to our site and look at the Components
section you'll see where you can download it. ZPublisher is just the ORB
part of Zope, it traverses your python module and calls your methods
based on the URL.

Now, you can still USE Zope with these application you write.  Even if
you write a pure ZPublisher application, you can then plug that
application right into Zope with the External Objects product available
in the contributed area.

but when I try to "import" it from python I get the following error:


Python 1.5.1 (#1, Mar 25 1999, 13:52:32)  [GCC 2.7.2.3] on sunos5
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import MySQL
Traceback (innermost last):
  File "<stdin>", line 1, in ?
ImportError: ld.so.1: python: fatal: relocation error: symbol not found: __umodd
i3: referenced in /usr/local/mysql/lib/mysql/libmysqlclient.so.5

I also tried it from a FreeBSD machine with pretty much the same result.

Any ideas.????

TIA

Subject: [Zope] Anyone using '-roman' in next-sequence tags?
Message-ID: <v04104402b3215abd54fb@[128.240.198.13]>

Hi all,
just thought I'd check my sanity here...

the way to get roman numerals showing up as the label on a batch object is :

      <!--#if previous-sequence-->
        <a href="<!--#var URL--><!--#var sequence-query -->query_start=<!--#var
                 previous-sequence-start-roman -->">
        (Previous <!--#var previous-sequence-size--> results)
        </a>

      <!--#/if previous-sequence-->
isn't it? - I get a NameError, with the following traceback ('sub' is 
nowhere in my document btw)

<!--
 Error type: 
 Error value: sub
 -->

....

Subject: [Zope] installing Zope
Message-ID: <3.0.1.32.19990326200338.009363e0@poirot>

Hi,

Thanks to all the reply I got for my question PHP3 or Zope.

I'm wanting to give it a try, but ....

I've RedHat 5.2 installed with running Apache

I'm trying to install Zope, but am expiering some problems :

I've downloaded the binary and installed it into 

 /usr/local/dc/Zope-1.10.2

installed it with ./install -sAdmin:Admin

the var directory of Zope is permissioned for nobody (done by Zope)

As in the manual, Zope created access with Admin:Admin, but it says login
with Zope:Admin

copied the Zope.cgi to the directory /home/httpd/cgi-bin

I want to use it with Apache so I had something to change in the conf file
of Apache... Apache has 3 conf files. At the moment it is written in all 3
of the files (because none of them work!).

This is the piece of script I've written : (from WEBSERVER.txt)

#Zope configuration maps /Zopz/ to the Zope.cgi CGI script

RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1
[e=HTTP-CGI-AUTHORIZATION:%1, t=application/x-httpd-cgi,l)]

When trying to browse to http://localhost/cgi-bin/manage I get the password
dialog... I enter Admin , Admin and am refused (same with Zope, Admin) ....

What am I doing wrong?????

--------------------------------------

Now try to use ZopeHTTPServer

I can't find anywhere the file serve.sh

BUT I tried to start it with start

then going to webbrowser http://localhost:9673/manage

I get a message of DNS problem etc...

So not even a question of password...

----------------


Can somebody tell me what I've done wrong? I want to get it to work with
Apache... What do I've to do?

Thanks in advance,

Tom.

Hi,

I noticed that if you're browsing two different Zope sites using the
same Netscape, the management tree on the second one is incorrectly
displayed (the COLSPAN is increased by two).

Has anyone noticed this before?

regards,
Nuno

Ok, I've updated the package to remove the bug that killed it after the
first shutdown/cache loss. The _v_ technique certainly served to prevent
the saving of the variable, so when the system came back up, before I
use the _v_ variable I was testing it to make sure it was higher than
the stored value. I added a test to make certain that it exists... Is
there a way to register a function (or some __func__) that gets called
the the instance is reloaded?

It seems fairly stable now, so I'm calling this 1.0. 

Please send bug reports to shawh@sths.org.

BTW, has anyone actually tested this other than me? 
I thought from the comments I had read on the list that there were a
fair number of people who were perturbed at the lack of a counter in
Zope. Was I wrong? Am I flogging a dead horse here?

Subject: [Zope] Method icons
Message-ID: <36FBFDF1.23E9F89A@digicool.com>

Hi all.  Here's a minor issue I'd like to get some opinions on.

  There are some ideas in Zope that cross 
  object types in Zope, like folders, methods, and
  content.  We reinforce the idea of folders
  by giving folders icons derived from folder
  icons.  I'd like to do the same thing for 
  methods.

  The basic idea is that there should be
  some basic icon that indicates that something is
  a method.

  It should be possible to decorate the icon to 
  indicate a particular type of method, such as adding
  angle brackets for DTML or adding a table grid
  for SQL, or OO (or glasses ;) for Python.

  Note that one complication is that the image 
  should fit in a 16x16 icon.

I've put some ideas at:

  http://www.zope.org/methodIcons

I'm curious what folks think of these and whether
anyone has any better ideas.

Jim

Hello!

http://www.postgresql.org/software/detail.cgi?oid=3440544

   I need a short informative description on Zope. Something like "Zope is
opensource web application platform - software complex for creating highly

   What is contact e-mail? I wrote zope@zope.org. Shouldn't it be

Subject: [Zope] Automatically creating instances for each user?
Message-ID: <36FE35BD.AEBBC507@dougiamas.com>

Hi,

I'm new to Zope, but I'm eagerly learning it.  I like the
paradigm - it seems to fit the way I think.

This is my first post here.  I've hit a snag, and I'm hoping
someone more experienced can point me in the best direction.

I'm developing an application that needs user-modifiable pages.
I already have a Zope form where the user can edit text properties
of an object, and another page that displays those properties as HTML.

My problem is, I want each authenticated user to be editing their 
own instance of this object, and I also want the URL to be the 
same for each user.

eg  fred sees http://host/mypage as fred's editable page
    mary sees http://host/mypage as mary's editable page

What is the best approach I should take to achieve this in DTML?

Cheers,
Martin

Yes, the documentation is a bit unclear about this.

You'll need a Database Connection String like this: 
"webdb joe password".

"webdb joe password" should work if the database is running on the same
machine.

Message-ID: <3.0.1.32.19990329102524.0097e170@poirot>

Hi all,

Well, now I don't understand it anymore....

Just back from the weekend (where on Friday I had these installation problems)

Now went to the Zope directory and what did I saw? The 'Start' and 'Stop'. 
I wrote ./Start and then surfed to the correct address and it works!

Why did'nt it worked on Friday? The whole weekend searching for a solution
and then it appears it isn't needed... (almost)

But, still I would like to work with Apache... Why? Because I've heard it's
the best in web-servers... (I don't know it's through, but I believe it) Or
is the comming ZServer better?

Now, I believe I have to recompile apache again to make it ready for Zope,
isn't it? I thought I only had to put it in one of the configuration files,
but instead you've to write that script in the ./configure file.

Kind Regards, Tom.

to install an external driver. 

Is it so that I've to recompile Zope? This means that I've to download the

Because when I need to recompile, I've do download also all the correct

Thanks in advance.

   You need to install and compile ZPygres Database Adapter and add it as
described in ZPygresDA docs. You don't need to recompile Zope.

AUTHENTICATED_USER.getUserName() returns the name of the current user. You
could use this in the DTML of mypage to select the object you are working on.

Hi all,

I'm using Zope 1.10 with IIS 4.0 on an NT box.  All is working well, I just
have one small query which is slightly off topic, maybe.

The URL for Zope is 'http://localhost/scripts/z.exe' and I would like it to
be 'http://localhost/z/', I know that with Apache I could do a rewrite and
this works great with Apache, but does anyone know how I would do something
similar with IIS.

TIA

Nope,

With that definition, my_method expect to be called with the arguments
set, eg <!--#var "my_method('Zope')"--> to display "Zope is cool".

However, I want to get the variable l from the namespace. (application
variables made with REQUEST.set, Folder or document properties, etc.)
The question was: is self.REQUEST the only way to access the
variable namespace? And the only way to *modify* the variable namespace
from external methods (with self.REQUEST.set)?

By the way, I'd like to thank Stefan Franke and Pedro Vale Lima who
gave me a pretty quick answer. I did find the answer before they wrote,
but anyway, a thank is not that expensive :-)
Also, thanks to Paul who gave me such a useless answer. :-) (just kidding)

Subject: [Zope] error in pcgi
Message-ID: <003601be79e7$80d806c0$147800a0@pc-pi0>

Hello,

my site was working great when suddenly, I got a "Temporarily unavailable"
message.
The pcgi.log reads:

unexpected out-of-bound data in stdin t[0]=60

several times. I suppose this means that something is writing to the
stream read by pcgi. I didn't do anything other than uploading new versions
of my DTML Documents to the site. (I have done this all the aternoon long).

Have you already seen this behavior? Does someone have an idea of
where to start to find the problem?

The error occurs because a value is appearing in
a pcgi reserved header record, possibly because your
application is sending something to stdout.  I'm
not sure where to tell you to start looking, but
if *all* you have done is uploaded .dtml files to
trigger the error, that's probably the place to
start.  I'm honestly confused why this should
happen.

Usually this means that the Zope process is unable to start up
for some reason (an import error, syntax error, etc.). I'm not
sure how changing DTML document objects could cause this, though.
You didn't happen to change any DTML that is read from the disk
(e.g., HTMLFile objects used from Zope, installed products or 
external methods) did you? If so, there is probably a dtml syntax
error that is being raised at startup time.

You are positively right.
I stupidly wrote <!--#var "some_method(var0=value0, REQUEST)"-->
notice the non-named parameter after a named parameter.

I haven't tried it yet with other publishing mechanisms (ZServer,
ZopeHTTPServer,
which don't use PCGI), but if these servers also dies for such oddities,
this might be
a bug in error handling. Stay tuned for more informations.

Many thanks to Brian and Jeff who took the time to respond to me.

All of my "real" sites are still running under Principia. Recently a

using the latest versions of IE and Netscape are unable to access the
sites now unless they turn off cookies, or they get an error in
cgi_module_publish to do with parsing cookies. (I'm still trying to get
someone to send me the actual error text).

Anyone out there using Principia still? Have you seen this?
Anyone using Zope seen this?

Message-ID: <613145F79272D211914B0020AFF6401907BBDA@gandalf.digicool.com>

Greetings,

As promised, it is possible now to browse the Zope public CVS repository
through the web.  If you're interested in looking at the latest Zope
developments, this is a good place to start without having the check out
your own copy.

This site is also handy for viewing the various evolutions of Zope, and
for getting pretty colored diffs between versions.  If you want to know
the difference between two recent versions of a certain file, cvsweb
will show you in glaring full color.

The web view of the Zope CVS is more fragmentary the the view you get
with the 'cvs' command.  If you want to check Zope out of the public
cvs, it is recommended you just check out 'Zope', which is an options
not shown on the web cvs.  The public CVS uses its module file to stitch
together the various components that can be seen on the web view into a
Zope distribution.  Complete instructions on how to do this can be found
at:

http://www.zope.org/Community/CVS_public_access

The web interface can be found at:

http://www.zope.org/cgi-bin/cvsweb.cgi

In case you're curious, this is not a Zope module but a CGI script
written in Perl.  It can be found at:

http://linux.fh-heilbronn.de/~zeller/cgi/cvsweb.cgi

The first release of Aqueduct docs had a table with examples of
connections strings for some databases. This table disappeared in the
latest docs. Shouldn't it be the case to take it back?

After everything compiled fine I try to import MySQL and get the following
error:

Does anyone have any ideas??
MySQL works fine as well as Zope.
Do I need to install the Sun ld.so patch??

Yes, I've seen it in Principia and Bobo for cookies in the form:

.com.au  TRUE    /       FALSE   933422008       MC1 GUID=083F5B8E21DE11D28B2C08002BB74F3F

The two problems being that cookies are usually only seen by the domain
that registers them, but some badly configured servers (most probably
Microsoft servers by the look of the cookies) only list the last two parts
of the domain name. This is fine for blah.com, but for overseas domains
like blah.com.au it means the cookie is returned for ALL .com.au sites.

This wouldn't be a problem, but since the cookies are returned to Principia
in the form:

MC1=GUID=083F5B8E21DE11D28B2C08002BB74F3F

parse_cookie breaks since it looks for key value pairs WITHOUT an equals
sign on either side. The extra = really confuses it.
To fix it change the re in parse_cookies in cgi_module_publisher.py from:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-=\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'
                     ),
 
to:

                 parmre=regex.compile(
                     '\([\0- ]*'
                     '\([^\0- ;,=\"]+\)=\([^\0;-\"]*\)'
                     '\([\0- ]*[;,]\)?[\0- ]*\)'
                     ),

I'd like to be more precise. Suppose my_method is:

def my_method(self):
    if self.REQUEST.has_key('my_var'):
        return "oh yes"
    return "boooo"


Now, I write in DTML:

<p><!--#var my_method--></p>
<p><!--#with "_.namespace(my_var='my_value')"-->
<!--#var my_method--><br>
<!--#var my_var-->
<!--#/with--></p>

Believe me or not, the result is:

boooo
boooo
my_value

You can now understand why I ask how to access the variable
namespace from external methods. How can I test the existence
of my_var, and access its value???

Keep the good work, I might ask you some of your photos for
my daily worship :-)

Hi,

I'm getting really frustrating on this subject. Pff, I believe the
Zope-people have made already a great effort in their documentation. So I
guess my problem is my own bad english. shhg.

I finally got the Postgressql adapter compiled, thanks to two great people!
Thanks for this already.

But now I'm confused? How to use it in Zope? When I go to the product
management I see the all the installed products including : ZPyGreSQLDA
(broken product APyGreSQL).... I guess here is already something wrong
(broken... is not a positive word :-( )

But then, how can I work with it? How can I use it in Zope...? How can I
add it to the 'Add list' . I read of a connection string... but where to
place it?

Sggh, I've read in the manuals, Q&A, ... but I still don't get how to use
it....

Please, somebody, help...!

Thanks in advance,

The Idiot,

Tom.

First thing, if your product is broken you won't get anywhere. So, first
step is to delete the broken product, and shutdown and restart your zope
server. This is because Zope apparently won't replace a broken product
with a working one. 

If it is still broken, click on it, and then on the screen that comes
up, look for the 'traceback' tab on the top of the screen. Copy this
traceback and mail it to the list. 

If your product no longer says broken, then you will be able to go to a
folder above where you want to use SQL methods, and from the pull-down
menu beside the add button, choose to install the SQL Adapter. 

I don't know for certain the format for the connection string, but if
you go to <zope_homedir>/lib/python/Products/ and look in the directory
for the ZPyGreSQLDA and read the top of any *.py file you see, it should
say. 

Once you have a working adapter, you can add an SQL Method, and it will
list your adapter's id on its list of db connections. 

From this point on the documentation in the SQL Guide should be
sufficient.

Good luck!

They'll want to be doing credit card transactions.  Has anyone been working on

Well, this is an interesting question. In my experience, seldom do people
try to munge the DTML namespace from within an External Method. I guess it
could be done (perhaps by passing the special underscore variable to an
External Method), but I wonder if this is really the best way to solve your
problem.

Well let's see what's going on here. You call my method, it acquires the
REQUEST object and looks for a 'my_var', doesn't see it and returns
'boooo'. so far so good. Now you push a namespace containing only 'my_var'
on to the DTML namespace stack and call the method again. Not surprisingly
the method does the same thing as before, it acquires the REQUEST and finds
that it does not contain 'my_var' so it prints 'boooo'. Finally you call
'my_var' which is found in the DTML namespace and 'my_value' is printed.

So the lesson is: the DTML namespace is not the same thing as the REQUEST
object.

For more on how DTML namespace works see my advanced DTML how-to:

http://www.zope.org/Documentation/HowTo/DTML

My advice to you is to keep things simple. It's easy to confuse yourself
with the complexities of DTML. In general, I would suggest that your
External Methods take well defined arguments and return results, rather
than modify the objects passed to them. Then allow the DTML to pass those
arguments and munge its own namespace in response to the results of the
External Method. Of course, this schema isn't always the right one. Finally
I would suggest that you, don't munge the DTML namespace from within an
External Method unless you have a good reason to, I think that this would
make the DTML even harder to understand.

Good luck.

Can I recover? The db doesn't contain anything important so it's really
okay to reinstall, should that be neccessary.

It looks like you're running an older release 1.9.x something?  1.10.x
will automatically fix the database under 90% of the circumstances by
simply truncating the bad record.  This should fix your problem.

BTW, it's always helpful to give information on what release of Zope
you're using.

At a minimum, you can truncate the data file (var\Data.bbb) 
at the position indicated. (Let me know if you need help with this.)

You could also just delete the database (var\Data.*) and
a new database will be created when you restart.

I'd appreciate it if you'd send me the corrupted database
as a zipped or gzipped attachment in a private email.

Also, what version of Zope were you running? What OS?
What products (not included in the Zope distribution) did
you have installed?  Can you tell me anything more about what 
might have led up to this?

I think what you want is access to the dictionary's items() right?

<!--#in "dictionary.items()"-->
  <!--#var sequence-key--> : <!--#var sequence-item-->
<!--#/in-->

The mapping attribute is not relevant here. It means treat
sequence-items as mappings not instances, that is to say, look up vars
with __getitem__, not __getattr__.

The DTML User's Guide is your friend.

Message-ID: <Pine.BSF.4.05.9903301224520.1978-100000@nomad.dataplex.net>

I'm trying to convert shell scripts into DTML methods.

Please excuse the pseudo code. I'm using it to represent the problems
that I am addressing.

set basket_total=0
set taxable_total=0
foreach item( 'apple', 'peach', 'soap', 'pear', 'plum', 'magazine' )
 if (! isfood($item))
  @ taxable_total = $taxable_total + price_of($item)
 endif
 @ basket_total = $basket_total + price_of($item)
endfor
print "Of the $basket_total total, $taxable_total is taxable"


1) Can I generate an explicit list rather than getting it with
as the result of either a database query or enumeration of an object?

2) How do I generate "local" variables.
I know that I could use the REQUEST variable as a global property store.
However, because of nesting, global (REQUEST) variables are not desirable.

I'd like to say something like the following:

<!--#WITH "LOCAL_NAMESPACE (basket_total=0, taxable_total=0)"-->
 <!--#FOR "['apple', 'peach', 'soap', 'pear', 'plum', 'magazine']"-->
  ...
  <!--#SET basket_total=basket_total+price ...>
 <!--#/FOR-->
 ...
 <!--#var basket_total--> 
 ...
<!--#/WITH-->

Does Zope's DTML have constructs to address either of these?

Message-ID: <370125A1.305733AC@kw.igs.net>

Please excuse my lack of zoping intuition but I hoped someone could help
with this problem. I read all the doc's I could find but seem to be
missing something. It goes like this...
I have a ZSQLMethod that returns some tuples. There is a field in the
tuple which I wish to use to lookup an external file and return a jpeg,
if available.
I've created an external method called 'getPic' which I wish to pass the
key field to locate the file with but I can't seem to get at the
variable.
e.g
----------
<!--#in sequence -->
  <td><!--#var pic_key null=""--></td>
  <td><!--#var "getPic( <!--#var pic_key --> )" --></td>
<!--#/in -->
----------

This doesn't work for reasons not obvious to me.

I've tried creating a class to handle the records. No go.
Basically, the External method can't get at the vars defined on each
loop thru the sequence returnd from the SQLMethod.

Any insight would be appreciated.

thanks

I would like to trigger a DTML document to print after the user creates
it. ( There are a few documents in my project that need to be snail
mailed)   
Circumstances aside, they aren't allowed to print from Navigator, so I'd
like Zope to shoot it out without the user having to have a printer
configured.  If a printer is configured to work with the server, can
Zope send it to lpr? I have zero experience there. :-(  

Any suggestions?

Brad,

Thanks.  Regretably, we aren't really using any Microsoft Products (Too
bad, we could have got a virus yesterday :-()  The clients are(and a
browser on the server could be) running Netscape Comm 4.08.  I'm sure
there is a similar way of controlling Netscape--Any body have a guess?

I am thinking about implementing a dynamic site using
zope and as little python as I can get away with.  The
site is modeled after
http://c2.com/cgi/wiki?WikiWikiWeb  

This is a dynamic site in that all the web pages are
dynamically generated and you are allowed to edit any
page right from your browser (sound familiar?) and also
create new pages very easily.  There are many other
implementation of wikiwiki (see the WikiWikiClones
link).

I am interested in any creative ways of dynamically
generating the pages and storing the underlying date in
the objectDB.  Thanks!  Mark

Hello,

Thanks for your answer.
In fact, I want to write external methods to replace DTML methods which work
like a charm, but are not very readable (a lot of iterative stuff, given the
fact
that mySQL doesn't support sub-select) and pretty slow.
I have used python for several years right now, but DTML is new for me.

My users can search in our news database in several ways, that are
covered by different SQL queries. However, the output of all these queries
are the same, so I use a single DTML method to display the result.
So the name of the ZSQL Method is only known at runtime, and I use something
like:

<!--#in "_[query]"-->

to display the result. The arguments of the query are taken from the
namespace.
I can also write:

<!--#with "_.namespace(cooked_arg0=some_expr(arg0),
cooked_arg1=some_expr(arg1)"-->
<!--#in "_[query]"-->
<!-- ... -->
<!--#/in-->
<!--#/with-->

If I want to cook some args before feeding it to the query.
All these work from DTML.

Now, I want to write this in an external method.

def results(self):
    for record in getattr(self, self.REQUEST['query'])(self):
        pass # do watever

'query' has to be in the form REQUEST variables (that is not a problem), but
I cannot be sure that any arguments that the query need are all accessible
through
REQUEST.

I wrote this to test wether an external method has access to the entire
namespace,
or only to REQUEST variables.

So I come back with the question: is there any way to access the DTML
namespace
from an external method. Apparently there is not

I have already read it.
By the way, let me ask you a question (again. I already asked that, but the
answer
was not very clear, and I finally gave up):

<!--#var my_var--> and <!--#var "_['my_var']"--> are the same.
So instead of writing:

<!--#if var0--><!--#if var1-->
<!-- ... -->
<!--#/if--><!--#/if-->

I usually write:

<!--#if "_['var0'] and _['var1']"-->
<!-- ... -->
<!--#/if--><!--#/if-->

But almost everyone told me that

<!--#if "var0 and var1"-->

also work. So I wonder: are <!--#var "var0"--> and <!--#var var0-->
the same??? The DTML User's guide say that in an expression,
variable are not called by default, but _['var0'] calls var0 if possible.

To keep things simple mean I have to write several times the same external
method
with different queries and differents arguments each time. this is not what
I want.
I can remember that in DTML I only need one DTML Method.
I would really like to replace some of my DTML Methods with external
methods.

That's enough for today. Let's take some rest :-)

Subject: [Zope] multiple SUBMIT buttons for same method, with parameter
Message-ID: <129.78.8.1.126.8141.922865008.414.1008>

I can use the following in a DTML document to call a specific method:

  <INPUT TYPE="submit" NAME="mymethod:method" VALUE="Delete this item">

But what if I wanted to have lots of them?

I'd like to have multiple SUBMIT buttons, all referring to the same method
but diffentiated by parameter - possible?

Ie: something like:

  <INPUT TYPE="submit" NAME="mymethod:1:method" VALUE="Delete item 1">

passing the parameter '1' to 'mymethod', and then later

  <INPUT TYPE="submit" NAME="mymethod:2:method" VALUE="Delete item 2">

and so on.

Incidentally, is the ':method' trick documented? - I can't find it in
the DTML guide.

Message-ID: <3.0.1.32.19990331105851.00931700@poirot>

Hi all,

First of all, thanks to all with their great support and help. At the end
of last week I found out about Zope. It looked really interesting, so I
wanted to give it a try. Monday after several problems and with lots of
help I could manage to enter Zope. Not from Apache as I would like, but
from the HTTPServer.
Next I wanted to attach Zope with my PostGresSQL demo database. Boy, did it
gave me some problems (and all because of my lack in knowledge of Linux).
But again several people helped me and today it is solved! Yep, it is done,
the hard work can begin. Now, I've to convince other people that Zope is
the way to follow. 

At first blink, Zope is a really nice and great product. I hope it will get
the attention it diserves.

Still, some work on the documentation, although they already did a great
job! Most thingies are written down.

Kind Regards, Tom.


Now some questions:

1. Have you used CSS-sheets in Zope and how did you use them? Did you
incorporated them into Zope or not? Have you got a little sample?

In Zope, this is pretty easy.
Create a property at your top level of type 'lines' and called 'css' 
(you can also create a DTML document/method if you like). Populate it 
with good CSS things like (this is from the Zope site itself 
actually).

<STYLE TYPE="text/css"><!--
	.clean { font: 10pt Verdana, Geneva, Arial, sans-serif }
	.clean dt { text-decoration: underline }
	th.clean { font-weight: bold; }
	.headbottomrow td { border-bottom: 2px solid #936 }
	.header { color: #004488; font-weight: bold; font-size: 14pt; 
font-family: sans-serif }
	.smallclean { font: 9pt Verdana, Geneva, Arial, sans-serif }
	.smallclean dt { text-decoration: underline }

H1, H2, H3, H4{
  font-weight: bold;
  color: #000000;
  font-family: Verdana, Helvetica, sans-serif;
}

H1{ font-size: 16pt;}
H2{ font-size: 14pt;}
H3{ font-size: 12pt;}
H4{ font-size: 10pt;}

/* end hiding content from old browsers */ -->
</STYLE>

In standard_html_header you put something like
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#var css-->
</HEAD><BODY BGCOLOR="#FFFFFF">

and you're away...

You may want to change standard_html_header so it doesn't crash if 
css is not present.
<HTML><HEAD><TITLE><!--#var title_or_id-->
</TITLE>
<!--#if css-->
<!--#var css-->
<!--#/if -->
</HEAD><BODY BGCOLOR="#FFFFFF">

Now where it starts to get really cool is that all your documents 
*below* the top level get the CSS information by acquisition, but you 
can change CSS information in folders by creating a new CSS property 
or document within that folder.

Tres Neat.

I just installed Zope on a Netscape Enterprise Server (3.6). I compiled
and installed the nscgiauth plugin, and all seems to run OK, except for
one thing:

When I try to add items to the site through the manage screen, I get:

        Not Found

        The requested object does not exist on this server. The link you
followed is either outdated,
        inaccurate, or the server has been instructed not to let you have
it. Please inform the site
        administrator of the referring page.

When I open the frame into a new window, I see that the URL looks
something like:

http://www.foo.bar.net/Zope/GATE/manage/.?%3Amethod=manage_addDTMLDocumentForm

When I edit the URL by hand to remove the "."

http://www.foo.bar.net/Zope/GATE/manage/?%3Amethod=manage_addDTMLDocumentForm

It works fine. What is going on here, and what do I need to do to change
it? I plan on having other people from other departments access resourses
on Zope to create their own objects, and I need this to work right out of
the box.

Thanks in advance for any help.

First off, your the first person (I think) that has come forward with
the information that they are using any version of NES higher than 2.0,
which is what the nscgiauth plugin was written for.  As I have heard
(but don't know) there were some significant changes between the 2.0 and
higher versions of the NSAPI.  So, that you got it to work at all is
pretty good.

This is unreported behavior, which leads me to think that nscgiauth
needs a little tweaking.  As nscgiauth is unsuported you will have to
experiment with this a little.

If your looking to showcase this and you can't spend any time working on
nscgiauth, I would suggest using either Apache, ZServer, ZopeHTTPServer,
or IIS, all of which Zope runs out of the box with.

I think that you missed my point.

"I" can write python just fine. However, every time something changes, new
python functions must be written. It is desirable to allow 
"DTML programmers" to do simple things which they can accomplish with simple
local variables.

What I think I should do is create a function, "LOCAL", similar to REQUEST
that stores temporary variables. Unlike REQUEST, LOCAL would be bound to
the namespace multiple times, each with a different context stack.

<!--#with "_.namespace(LOCAL=LOCAL.create('basketTotal','taxable')"-->
  <!--#call "LOCAL.set('basketTotal', 0)"-->
  <!--#in "['pear', 'peach', 'boot']"-->
    <!--#call "LOCAL.set('basketTotal',
                             LOCAL.get('basketTotal')
                             + priceOf(_['sequence-item']))"-->
  <!--#/in-->
The total basket will cost <!--#var "LOCAL.get('basketTotal')"-->  
<!--#/with-->

Or perhaps we can trick the namespace into showing basketTotal without

Can the Zope server provide virtual domains or do I need to use Apache??
Right now I have Apache set up with 4 virtual domains and would rather
just use the default Zope httpserver.

Well, the only difference that stuck out to me were the include files for
NSAPI.
nscgi  calls for several, but in 3.x all the header files have been
combined into
one, "nsapi.h". I modified nscgi.c to call for this one header file and it
compiled
cleanly. It does its job very well, and am not all that certain that the
problem I
am having is related to nscgi at all.

Well, I am a contractor and really don't have that option. I have tried to
sell the idea of using Apache here, but they have already bought massively
into Netscape. If I cannot get Zope to work, I may end up recommending a
commercial package, at least for this case.

Message-ID: <Pine.LNX.3.96.990331124956.26207A-100000@taos.kavi.com>

Has anyone built Zope on a BSDI machine? BSDI doesn't support shared
libraries, so everything has to be statically compiled into python.
I just got it to build (python w_pcgi.py finished), but there doesn't seem
to be a new python binary anywhere with everything compiled in. To get it
to compile, I went through and deleted all the '*shared*' from the 'Setup'
files. Any tips?

As a side note, I was planning on using the binary porting kit to get it
built, then contributing this back to the community. But the porting kit
is still Zope-1.9. Is there any plans to update the porting kit.

Thanks in advance for any help,

Subject: [Zope] NotMail 0.1.0 and IMAPAdapter 0.1.0
Message-ID: <613145F79272D211914B0020AFF6401907BBF0@gandalf.digicool.com>

Greetings,

NotMail-0.1.0 and IMAPAdapter-0.1.0 have been posted to the prereleases
area of the site:

http://www.zope.org/Download/Prereleases/Mail

These are first beta cuts.  Both programs are also available in the
public CVS.

IMAPAdapter allows you to work with IMAP folders and messages in the
context of an authenticated IMAP user.  Using IMAPAdapter, it is very
easy to build IMAP client functionality into your Zope site using DTML.

NotMail is a simple web IMAP client that requires IMAPAdapter.  Its mail
purpose is to verify the operation of IMAPAdapter and to provide an
example implimentation of IMAPAdapter's client functionality.  NotMail
is mostly DTML, and what Python there is is just specific to sending and
replying to mail, all other functionality comes from IMAPAdapter.

It is important to note that IMAPAdapter looks like a user folder to
Zope, in Zope parlance, we call this a user database.  It's not a user
folder, because it doesn't not contain users.  If Zope tries to validate
a user against an IMAPAdapter, the IMAPAdapter will contact the IMAP
server, try to make a connection with the uid:pwd that the browser
supplied, returning either a user object or None, depending on the
success or failure of that connection attempt.

This means that using IMAPAdapter is quite simple.  Here is a snip of
DTML to display all an IMAP users mail folders with the #tree tag.

   <!--#var standard_html_header-->
      <!--#with AUTHENTICATED_USER-->
        <!--#tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1-->
	    <img src=<!--#var icon-->>
	    <!--#var shortname-->
	    <!--#if num-->
	      (<!--#var num-->)
	    <!--#/if-->
        <!--#/tree-->
      <!--#/with-->
    <!--#var standard_html_footer-->

The user object that IMAPAdapter returns (if the user is valid) is
placed into AUTHENTICATED_USER.  emapFolderTree is one method of this
user object, but there are about a dozen or so more methods to do
various imap related things like adding/deleting folders and listing and
fetching messages.

If you plan on installing and trying out NotMail and IMAPAdapter it is
important to know that you can configure the roles that IMAPAdapter
associates with users that it returns.  The two default associated roles
are 'NotMail' and 'IMAPUser'.  If you want NotMail to work, you will
need to add one of these roles (or any roles you care to define as
IMAPAdapter's default roles) somewhere above NotMail/IMAPAdapter and
then assign that role the 'View' permission for NotMail's DTML Methods.

Have Fun!

-Michel

Um, what VERSION of BSDI are you using?  I haven't usd anything since
3.0, but I SWEAR it has standard BSD style shared libraries, same as
FreeBSD, OpenBSD and NetBSD... It'd be a huge step backwards if it
didn't.... are you sure it just didn't auto-detect the method right?

Alright, I guess I was jumping the gun a bit with my assumptions about
shared library support. It does support them, just not in a format I'm
used to (based on my Linux/Solaris experience). 

Ok, so then mabey I messed up in autodetecting as you mentioned. How would
you suggest I do this?

Here's a few lines of the errors it reports when trying to compile any of
the shared extensions... 

www ~/Zope-1.10.2-src/lib/python/SearchIndex 242> make
gcc  -g -O2 -I/usr/local/include/python1.5 -I/usr/local/include/python1.5
-DHAVE_CONFIG_H  -I/projects/_/python -c ./Splitter.c
ld  Splitter.o  -o Splitter.so
./Splitter.c:105: Undefined symbol _PyString_AsString referenced from text
segment
./Splitter.c:114: Undefined symbol _free referenced from text segment
./Splitter.c:126: Undefined symbol _PyString_Type referenced from text
segment
etc.... (many more Undefined symbol errors)


So... any tips for compiling the Zope extensions as shared libs? I'll
probably keep working on the static python solution, as I'm actually
making progress on this, and I really have no idea where to start with
shared libs on BSDI (no good leads on dejanews, and egroups is
non-responsive as usual).

Thanks,

When I try to access http://somedomain/cgi-bin/Zope.cgi/manage
I get the following error in the http-error log:

Here are some things I've found in previous struggles to
get Zope compiled on bsdish systems -- I'm no guru, though,
and I've seen different things work on different bsdx flavors:

o you usually need to add -rdynamic to LDSHARED in your Makefiles
  (this should be reported & worked into python's makefiles, IMHO)

o I havent been able to get threads going on many bsd flavors - so
  you may not be able to pass --with-thread to configure

o I find that extensions will all appear to blow up with unfound symbols

  (such as those you reported) - you need to run make -k and ignore the 
  errors ;)

o On some systems, I had to run make -k, ignore the errors, and rename
  the output .o files for the extensions to .so :(

o I seem to remember having to use shlicc on .so files, but
  I dont recall the details...

Hope this helps - please post a status rpt if you get it working, so
that the gory details will at least be captured. This is the sort of
thing that should be in an installation FAQ somewhere.

In the pcgi/Util directory, you'll find a killpcgi.py 
script.  You could hack it to perform a restart, i.e.
launch a new pcgi process after killing the old one.
This would speed up your initial connect time and be
much faster during debugging (multiple restarts).
