It guides you through installing and running Zope. This chapter covers the most important Zope concepts. By the end of this chapter you should be able to use Zope to create and manage simple yet powerful web applications. % Anonymous User - July 5, 2002 3:42 pm: Chapter Two consists of a number of sections ... maybe something of a ToC here would help navigate this rather large slab of text. % Anonymous User - July 25, 2002 8:35 pm: I was unsure where to place this comment; and it may not be useful. I am new to Zope and have been proceeding through the Chapters one at a time, one thing I thought might be advantageous but a bit of an undertaking is to suggest that initially the user creates for themselves a 'Sanbox' folder or something similar in order to experiment with the given examples. I did this almost right away as soon as I discovered I was litering my Root or contained folders with little snippets of script or object experiments. Just a suggestion. Thank-you for this wonderful document. % mcdonc - Aug. 11, 2002 7:18 pm: test From chrism@zope.com Mon Aug 12 00:18:55 2002 From: chrism@zope.com (Chris McDonough) Date: 11 Aug 2002 19:18:55 -0400 Subject: [ZDP] Incoming mails from ZopeBook/ZDG Message-ID: <1029107944.32551.92.camel@james> I have re-enabled incoming "comment" mails from the Zope Book and Zope Developer's Guide.

It has three distinct audiences: % chrism - Dec. 10, 2001 11:02 am - Note that folks are encouraged to make comments using the comment system. Thanks! *Users* -- individuals who use of Zope's "out of the box" features to build websites. This audience is interested in making use of Zope's existing array of features to create content management solutions. They will likely make heavy use of "through the web" scripting using DTML, Page Templates, and Python Scripts as well as (of course) HTML and XML. They are generally less concerned about code reuse than the speed at which they can create a dynamic application or website. *Developers* -- individuals who wish to extend Zope to create highly customized solutions. This audience is likely interested in creating highly reusable custom code that makes Zope do something new and interesting. *Administrators* -- individuals responsible for keeping a Zope site running and performing installations and upgrades. % Anonymous User - Apr. 16, 2002 6:20 pm: Term 'Users' mean 'End user'. Better to use term 'content managers'. Main Zope's roles (audiences) are: content managers, developers, administrators. % Anonymous User - June 3, 2002 6:27 pm: "speed at which" should be "speed with which" % mcdonc - Aug. 11, 2002 7:23 pm: test From nobody@nowhere.com Mon Aug 12 13:38:40 2002 From: nobody@nowhere.com (nobody@nowhere.com) Date: Mon, 12 Aug 2002 08:38:40 -0400 Subject: [ZDP] BackTalk to Document The Zope Book (2.5 Edition)/Preface Message-ID: A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZopeBook/current/Preface.stx#1-0 --------------- Welcome to *The Zope Book*. This book is designed to introduce you to Zope and its uses. Zope is an open-source web application server. If you are interested in writing web pages, programming web scripts, using databases, managing content, or doing a collaborative web development task, then you should read this book. % mcdonc - Apr. 5, 2002 4:01 pm: Please note that folks are encouraged to use the comment buttons to submit comments. Thanks! % Anonymous User - Apr. 5, 2002 6:44 pm: The "Comment" buttons are too distracting. I like the idea but small icon on the right in the pastel colour should be enough. Large yellow button makes reading the text rather hard. % Anonymous User - Apr. 6, 2002 12:03 am: Not to "me too", but ditto on the previous comment regarding the Comment button. % Anonymous User - Apr. 6, 2002 10:36 am: Use the "COM off"/"COM on" button at the top to control whether or not comments and comment buttons are displayed. % Anonymous User - Apr. 6, 2002 8:07 pm: Turning COM off does not address the previous comments with which I concur. Why make Comment a graphic? Just make it a link on the right of the page so it isnt so distracting. % Anonymous User - Apr. 6, 2002 8:22 pm: At this point, it's a tradeoff. Please try to live with it now until I can figure out how to make it appear on the right of the page without effecting layout. Note that the COM button should set a cookie that turns comments off for all pages forever (or until you flush the cookie), but this is currently broken under some versions of Mozilla. % Anonymous User - Apr. 6, 2002 8:32 pm: Note also that you may download the HTML version and the PDF version for your own private viewing as well. % Anonymous User - Apr. 25, 2002 9:04 am: You should have your page in utf-8 if you were to allow people to add comments. Below we have an example that people add non-ascii text already. % mcdonc - May 10, 2002 2:33 am: Nope, no UTF8, sorry, and possibly never will be. But the comment cookies are fixed. They should persist across pages now. - chrism % Anonymous User - May 23, 2002 9:55 am: Your table of contents is not agreeing with your chapter numbers and also is not agreeing with your PDF.

This book is designed to introduce you to Zope and its uses. Zope is an open-source web application server.

Thanks! % Anonymous User - Apr. 5, 2002 6:44 pm: The "Comment" buttons are too distracting. I like the idea but small icon on the right in the pastel colour should be enough. Large yellow button makes reading the text rather hard. % Anonymous User - Apr. 6, 2002 12:03 am: Not to "me too", but ditto on the previous comment regarding the Comment button. % Anonymous User - Apr. 6, 2002 10:36 am: Use the "COM off"/"COM on" button at the top to control whether or not comments and comment buttons are displayed. % Anonymous User - Apr. 6, 2002 8:07 pm: Turning COM off does not address the previous comments with which I concur. Why make Comment a graphic? Just make it a link on the right of the page so it isnt so distracting. % Anonymous User - Apr. 6, 2002 8:22 pm: At this point, it's a tradeoff. Please try to live with it now until I can figure out how to make it appear on the right of the page without effecting layout. Note that the COM button should set a cookie that turns comments off for all pages forever (or until you flush the cookie), but this is currently broken under some versions of Mozilla. % Anonymous User - Apr. 6, 2002 8:32 pm: Note also that you may download the HTML version and the PDF version for your own private viewing as well. % Anonymous User - Apr. 25, 2002 9:04 am: You should have your page in utf-8 if you were to allow people to add comments. Below we have an example that people add non-ascii text already. % mcdonc - May 10, 2002 2:33 am: Nope, no UTF8, sorry, and possibly never will be. But the comment cookies are fixed.

You actually get a lot of things. Zope consists of several different components that work together to help you build web applications. Zope comes with: A Web server -- Zope comes with a built in web server that serves content to you and your users. Of course, you may already have an existing web server, such as *Apache* or *Microsoft IIS* and you may not want to use Zope's. Not to worry, Zope works with these web servers also, and any other web server that supports the Common Gateway Interface (CGI). A Web based interface -- When you build web applications with Zope, you use your web browser to interact with the Zope *management interface*. This interface is a development environment that lets you do things like create web pages, add images and documents, connect to external relational databases and write scripts in different languages. An object database -- When you work with Zope, you are mostly working with objects that are stored in Zope's object database. Zope's management interface provides a simple, familiar way to manage objects that resembles the way many common file managers work. Relational integration -- You don't have to store your information in Zope's object database if you don't want to, because Zope works with other relational databases such as *Oracle*, *PostgreSQL*, *Sybase*, *MySQL* and many others. Scripting language support -- Zope allows you to write web applications in a number of different languages, like "Python":http://www.python.org/, "Perl":http://www.perl.org/, and Zope's own Document Template Markup Language (DTML). % Anonymous User - July 23, 2002 6:23 pm: Sentences like "You actually get a lot of things." are a waste. It's why so much documentation is long and unfinished. The information content of that sentence is 0 or even negative. It pushes an opinion. It causes us to wonder if the author is sticking to the facts or has an agenda. We, the readers, will decide what we care about. And if we do care about quantity, we will judge for ourselves whether it is "a lot". Fluff is very annoying when skimming rapidly for meat. % dave_newton - Aug. 12, 2002 8:33 pm: HOw ironic.

You will be prompted to login again. To change logins, enter a new user name and password. % Anonymous User - May 19, 2002 1:25 pm: I selected logout and 3 times it asked for a login username and password. I had previously added a test user named bob, password bob. I entered this and the login appeared 3 times and in the end it didn't log me in. I have to close my browser and restart to get back in, and only then would it automatically log me in as my manager account, without prompting me for a password. I still cannot log in as bob. % Anonymous User - June 12, 2002 10:49 pm: The same appears to be happening for me. The client side script that brings up the login window is doing so before a refresh has gone through to perform the logout operation (at least that seems to be what's going on). % Anonymous User - June 12, 2002 10:50 pm: I just posted that I'm having the same problem. I should note that I'm using the latest version of IE6 on windows xp. % Anonymous User - June 15, 2002 10:16 am: Same here, but it seems to help to cancel the re-login first. Furthermore after a successfull re-login the old user is mentioned in the upper frame. % Anonymous User - June 19, 2002 11:25 am: Im also using windows xp, i canceled the first re-login and the closed the explorer instance, then i had to delete the historial and temporary internet files (menu tools->internet options) to log as a different user. Seems this has to do with windows xp dealing by its own with the "user cache". % Anonymous User - July 3, 2002 1:06 am: All you have to do is logout, then put the cursor in the location bar and hit enter on the /manage url - when the box pops up asking for a login and password, type in the new ones. % Anonymous User - July 10, 2002 1:00 pm: I have been stepping through this tutorial using Mozilla and Opera running on my linux box (Mandrake 8.2). I experienced exactly the same behavior that is described in the messages above. As an experiment, I created a new user in Mozilla and then went over to Opera to try to login as the new user. When I typed in the /manage URL and pressed I found myself logged in as the new user with no prompt for a password. % mcdonc - July 10, 2002 2:01 pm: I highly doubt that this happened exactly as you describe. Try this: close mozilla (all windows) close opera (all windows) 1. open mozilla and visit /manage 2. log in as an existing manager user 3. create a new account 4. open opera and visit /manage 5. log in as the newly created user. If at step 4 you are logged in as the user that you created in step 3, the world has finally ended, the milennium has come, and we've got larger things to worry about. ;-) % Anonymous User - Aug. 1, 2002 3:07 pm: I'd note that if I've logged in as Emergency User in a browser, my experience has been that I cannot log in on that browser as a regular user - whether I touch any of the acl_user entries or not. This distinction is otherwise undocumented, and for new users is a sufficient show-stopper to lead many to uninstall Zope if they can't find a clear answer. A quick observation - the answers given in the June 15 and July 3 messages don't work with my system - I need another browser to actually log in as a regular user. From my perspective, if the solutions are this inconsistent, then Zope itself needs design work on this point - urgently. % Anonymous User - Aug. 13, 2002 2:36 am: Windows 2000 user, Netscape 4.7. I hit the Logout button, and Netscape popped an "authenticate" box. I tried logging in here, since that seemed like the obvious thing to do, but received "Authentication Failure". Finally I hit cancel, and Zope gave me the message "You have Logged out". I was then able to log in with the new user.

Are we HTTP saving/updating index_html (i.e. just saving the changes directly from maya into Zope using HTTP rather than using ZMI?).

A couple suggestions to make it hopefully more clear: 1. Tell us which protocol is being used with this "save to URL" function of your HTML editor. Is it HTTP PUT? Something else? Beats me. 2. Give primary instructions in a non-specific manner (i.e., tell us to use the ZMI first). Then say something like "If your HTML editor supports [protocol], you can use it save to the URL of the index_html Page Template followed by /source.html. % Anonymous User - Aug. 13, 2002 2:52 pm: Hey "mcdonc", at this point we'd like to know ANY editor that works. whether current or old versions!

There is no other website I know about that lets psuedoanonymous people *write and run their own code* on the website itself. Lots of people write bad code. ;-) It's not really the framework's fault. It's intended as more of a demonstration of the flexibility and security of Zope rather than the raw speed of Zope. Also, FWIW, the comment dates mean very little. Zope.org does a much more than just serve this book. There are over 20,000 discrete pieces of content in this site, many of which are writable (not just readable). Note also that the largest known Zope cluster has serviced peak load of 900 requests per second.

Since Zope is free, you can download the latest version, and begin working immediately. % Anonymous User - Apr. 24, 2002 3:52 am: What advantage does Zope have over Dreamweaver or Namo Webeditor in designing the website pages??? % Anonymous User - Apr. 26, 2002 8:27 pm: you might use Dreamweaver to design a template, but then go through zope's web interface to write specific content for each individual page - at least, that's how it looks to me from what I've read so far. % Anonymous User - July 23, 2002 7:39 pm: Dreamweaver is mainly a "design tool", not a comprehensive web application framework. With dreamweaver you can produce "web pages" organized in a fairly basic "web site" of a rather static nature. Dreamweaver is meant for visually-oriented developers who do not mind delivering sub-par bloated code to http clients. Zope allows you to build "web applications", whose components can be highly-aware "objects". Those objects can grealty increase your site's modularity, flexibility and extensibility using such mechanisms as inheritance. As an example, a sub-section object will look for its own "header" object and if it does not have one, it inherits its parent's. So if you want to build a web application which lives and breathes, is managed and edited by a group of people, Zope is for you. % Anonymous User - Aug. 17, 2002 8:36 pm: You can also use Zope & Dreamweaver together. Even without destroying the logic in the zope templates, since DW leaves them untouched. I's really useful if you collaborate with a designer (or developer, depends on point of view ;)) on a project at the same point of time From nobody@nowhere.com Sun Aug 18 01:44:13 2002 From: nobody@nowhere.com (nobody@nowhere.com) Date: Sat, 17 Aug 2002 20:44:13 -0400 Subject: [ZDP] BackTalk to Document The Zope Book (2.5 Edition)/Introducing Zope Message-ID: A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZopeBook/current/IntroducingZope.stx#1-0 --------------- This chapter explains what Zope is and who it's for.

You also learn about the differences between Zope and other web application servers. % Anonymous User - May 27, 2002 5:06 pm: The second sentence should read: You _will_ also learn about the differences between Zope and other web application servers. % Anonymous User - June 28, 2002 8:56 pm: I've heard good things about Zope. Plone looks cool. I would really like to be able to use this product - but the SLOW PERFORMANCE of the zope.org site forces me to say no. I'm going through this site at 6pm (PST) on a Friday night, and it is dog slow. In addition, I can tell from the dates on the comments that overall traffic is not too heavy. As a business person, I can tell you that this product will never be as successfull as others out there unless performance is improved DRAMATICALLY. % mcdonc - June 28, 2002 9:12 pm: That was probably me. I was copying large chunks of the Zope Book around and generally otherwise giving Zope.org a workout. Sorry.. I wouldn't necessarily judge Zope solely on the performance of Zope.org at any given time. There is no other website I know about that lets psuedoanonymous people *write and run their own code* on the website itself. Lots of people write bad code. ;-) It's not really the framework's fault. It's intended as more of a demonstration of the flexibility and security of Zope rather than the raw speed of Zope. Also, FWIW, the comment dates mean very little. Zope.org does a much more than just serve this book. There are over 20,000 discrete pieces of content in this site, many of which are writable (not just readable). Note also that the largest known Zope cluster has serviced peak load of 900 requests per second. I think this is a good indicator that Zope is fast enough for almost anything, given the right setup and environment. It's quite understandable to want to judge Zope based on Zope.org, but you'd help yourself by doing a bit more research before jumping to any conclusions. % mcdonc - June 28, 2002 9:14 pm: One other thing: if you think Friday night isn't "geek night" for Zopists who use Zope.org, I'd have to disagree. ;-) % Anonymous User - July 27, 2002 11:56 pm: Yup (in regards to perfomance). I'm admining a site that on a single 200mz (actually 233 underclocked to 200 for stability) debian box , running Zope for multiple department squishdot's and the wiki's (awesome intranet tool!) , acting as an appletalk fileserver for over thirty machines, email, and even a covert tinymush server(!) and trust me, Zope is the least of my worries. It gets pounded constantly by departmental dudes whacking stuff on and off all day. It don't even blink. As to learning Python, don't worry! Theres a tutorial in the standard python distro that'll have you up to scratch in an afternoon. It's that easy! % Anonymous User - Aug. 16, 2002 6:21 pm: I have about 500 hits per second on a songle IIS site. 1 processor - no tuning - no cluster.

References: Message-ID: <006d01c24746$b7716520$2201000a@james> Errr.. searching Google, probably. ;-) Each Zope Product registers a number of object constructors that are made available from Zope objects. Typically, these constructors are accessible via the "manage_addProduct" mapping such as: anobject.manage_addProduct['SomeProductName'].manage_addSomeClass('id' ) This adds an instance of SomeClass to "anobject" with an id of 'id'. A shortcut for this is sometimes: anobject.manage_addSomeClass('id') Unfortunately, this doesn't work for all classes nor is there any sane naming convention. This is neither explained nor readily explicable, and is an example of Zope "DWIM" that really kicks documentors where it hurts.

The time and date corresponding to 0 in an operating system's clock and timestamp values.

System time is measured in seconds or ticks past the epoch. Weird problems may ensue when the clock wraps around (see wrap around), which is not necessarily a rare event; on systems counting 10 ticks per second, a signed 32-bit count of ticks is good only for 6.8 years.

Are there any techniques to make it became a base class extensible by ZClasses? The strange thing is that further on an __init__.py example shows how to register a class so to make it available to ZClasses for inheriting, and the __init__.py file of the Session product follows such registration directives! To be honest, it calls context.registerClass(), not context.registerBaseClass(). Maybe that's the point?

By design, different objects handle different parts of your application. Some objects hold your content data, such as word processor documents, spreadsheets and images. Some objects handle your application's logic by accepting input from a web form, or executing a script. Some objects control the way your content is displayed, or *presented* to your viewer, for example, as a web page, or via email. In general Zope objects take three types of roles: Content -- Zope objects such as documents, images and files hold different kinds of textual and binary data. In addition to objects in Zope containing content, Zope can work with content stored externally, for example, in a relational database. Logic -- Zope has facilities for scripting business logic. Zope allows you to script behavior using Python, Perl, and SQL. "Business logic" is any kind of programming that does not involve presentation, but rather involves carrying out tasks like changing objects, sending messages, testing conditions and responding to events. Presentation -- You can control the look and feel of your site with Zope objects that act as web page templates. Zope comes with a tag based scripting language called the Document Template Markup Language (DTML) to control presentation. % Anonymous User - May 31, 2002 10:39 am: This three types are a bit artificial. I agree with the CONTENT. I also agree on the LOGIC section. But I am having some problems with the PRESENTATION layer. DTML (why did you not mention ZPT) is a mixture of LOGIC, CONTENT and PRESENTATION. After all I would say DTML belongs to the realm of LOGIC. It is a "programming" language and not "really" responsible for PRESENTATION. It is a means of bringing content into a site... but like HTML which mixes STUCTURE (

etc.) and PRESENTATION () it is neither fish nor flesh. CSS is an example for "pure" PRESENTATION. I read an article that said, ZOPE had a problem with the separation of CONTENT - LOGIC - PRESENTATION. To me it looks as if the explanation tries to show the opposite... well, it failed and creates an artifical and wrong separation of CONTENT, LOGIC and PRESENTATION. % Anonymous User - July 2, 2002 1:49 pm: Can somebody confirm this: DTML is going away and ZPT will play a bigger role? If this is the case, I don't want to learn DTML. Zope should have a section where both Zope and users can post any new "trend" or future changes. Thanks. % Anonymous User - Aug. 21, 2002 10:39 am: "...it is neither fish nor flesh." Should be "neither fish nor fowl."

Database Connections must be established before database methods can be defined. Moreover, every Z SQL Method must be associated with a database connection. Database adapters (or DAs for short) are available for a number of databases: Oracle -- Oracle is a powerful and popular commercial relational database. This DA is written and commercially supported by Zope Corporation. Oracle can be purchased or evaluated from the "Oracle Website":http://www.oracle.com/. Sybase -- Sybase is another popular commercial relational database. The Sybase DA is written and commercially supported by Zope Corporation. Sybase can be purchased or evaluated from the "Sybase Website":http://www.sybase.com/. ODBC -- ODBC is a cross-platform, industry standard database protocol supported by many commercial and open source databases. The ODBC DA is written and commercially supported by Zope Corporation. PostgreSQL -- PostgreSQL is a leading open source relational database. There are several database adapters for PostgreSQL including "ZPoPy":http://sourceforge.net/projects/zpopyda/ which is maintained by Zope community member Thierry Michel. You can find more information about PostgreSQL at the "PostgreSQL web site":http://www.postgresql.org/. MySQL -- MySQL is a fast open source relational database. You can find more information about MySQL at the "MySQL web site":http://www.mysql.com/. The MySQL DA is maintained by Zope community member Monty Taylor. Interbase -- Interbase is an open source relational database from Borland/Inprise. You can find more information about Interbase at the "Borland web site":http://www.borland.com/interbase/. You may also be interested in "FireBird":http://sourceforge.net/projects/firebird which is a community maintained offshoot of Interbase. The Zope Interbase adapter is maintained by Zope community member Bob Tierney. Gadfly -- Gadfly is a relational database written in Python by Aaron Waters. Gadfly is included with Zope for demonstration purposes and small data sets. Gadfly is fast, but is not intended for large amounts of information since it reads the entire database into memory. You can find out more about Gadfly at the "Chordate website":http://www.chordate.com/gadfly.html. % Anonymous User - May 30, 2002 4:03 pm: Whoa! "Database Adaptors" come out of left field, with no description of what they are and how they fit into the scheme of "Database Connectors" and "Z SQL Methods", both of which have been described and related to each other. % Anonymous User - June 26, 2002 2:33 pm: I have figured this out; you only need a Connection object for the specific database, for example zope includes Z Gadfly Connection, you can install the MySql Connection and you will use the same Z Sql Methods as always, the connector will do the job of translating the zope languaje to the database interface... is this right? % Anonymous User - June 26, 2002 4:33 pm: This is right. Although you aren't *limited* to one, you can have several different database connections for each kind of database. For example, you can have two MySQL connections in the same Zope, each of which point to a different MySQL database. % Anonymous User - Aug. 22, 2002 4:55 am: I was wondering whether each user is handled in a different session. So if 2 users connect to a site (not cached) that uses batching. Will each user be handled separately or could there be a conflict? The same applies to the connection: Is each user using the same connection? Does Zope handle the sharing of this single connection? The same applies to the ZSQL as well of course. -Mac- From nobody@nowhere.com Thu Aug 22 10:10:52 2002 From: nobody@nowhere.com (nobody@nowhere.com) Date: Thu, 22 Aug 2002 05:10:52 -0400 Subject: [ZDP] BackTalk to Document The Zope Book (2.5 Edition)/Variables and Advanced DTML Message-ID: A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZopeBook/current/AdvDTML.stx#2-37 --------------- The *getitem* function takes the name to look up as its first argument.

A parameter gives a script more information about what to do. When you call a script from the web, Zope will try to find the script's parameters in the web request and pass them to your script. For example if you have a script with parameters *dolphin* and *REQUEST* Zope will look for *dolphin* in the web request, and will pass the request itself as the *REQUEST* parameter. In practical terms this means that it is easy to do form processing in your script. For example here is a form:: Name
Age

Will it work with Win 95/98/ME, or only NT/2000? -- Oryx3 % mcdonc - May 29, 2002 5:29 pm: It "officially" works on Windows NT/2000, although it reportedly also works fine on 95/98/ME and XP. % Anonymous User - July 24, 2002 12:47 pm: I'm using it on Windoze-Xp and it runs and feels like a solid app. Of course, I am weaning myself of M$S products in favour of Liunux, NetBSD and FreeBSD via GNOME 2 or KDE 3, so I hope it's just as easy to install on those platforms too. % Anonymous User - July 24, 2002 12:50 pm: ...and by the way, I leave my Windoze machine on 24/7 and keep Zope on just to see how it behaves with my other apps. It just keeps humming away using little resources hoping to get its share of requests. :-) Awesome product (so far!!). Romulus ========= % bazzo - Aug. 4, 2002 8:28 am: Zope 2.5.1 does not run on my Win98. After installation I d/clicked START.BAT, after quite a while I got the result about mounting the database, but when I inserted http://localhost:8080/manage at the IE I got "Server not found" I would have looked into the FAQ before if I would have found...

You will be prompted to login again. To change logins, enter a new user name and password. % Anonymous User - May 19, 2002 1:25 pm: I selected logout and 3 times it asked for a login username and password. I had previously added a test user named bob, password bob. I entered this and the login appeared 3 times and in the end it didn't log me in. I have to close my browser and restart to get back in, and only then would it automatically log me in as my manager account, without prompting me for a password. I still cannot log in as bob. % Anonymous User - June 12, 2002 10:49 pm: The same appears to be happening for me. The client side script that brings up the login window is doing so before a refresh has gone through to perform the logout operation (at least that seems to be what's going on). % Anonymous User - June 12, 2002 10:50 pm: I just posted that I'm having the same problem. I should note that I'm using the latest version of IE6 on windows xp. % Anonymous User - June 15, 2002 10:16 am: Same here, but it seems to help to cancel the re-login first. Furthermore after a successfull re-login the old user is mentioned in the upper frame. % Anonymous User - June 19, 2002 11:25 am: Im also using windows xp, i canceled the first re-login and the closed the explorer instance, then i had to delete the historial and temporary internet files (menu tools->internet options) to log as a different user. Seems this has to do with windows xp dealing by its own with the "user cache". % Anonymous User - July 3, 2002 1:06 am: All you have to do is logout, then put the cursor in the location bar and hit enter on the /manage url - when the box pops up asking for a login and password, type in the new ones. % Anonymous User - July 10, 2002 1:00 pm: I have been stepping through this tutorial using Mozilla and Opera running on my linux box (Mandrake 8.2). I experienced exactly the same behavior that is described in the messages above. As an experiment, I created a new user in Mozilla and then went over to Opera to try to login as the new user. When I typed in the /manage URL and pressed I found myself logged in as the new user with no prompt for a password. % mcdonc - July 10, 2002 2:01 pm: I highly doubt that this happened exactly as you describe. Try this: close mozilla (all windows) close opera (all windows) 1. open mozilla and visit /manage 2. log in as an existing manager user 3. create a new account 4. open opera and visit /manage 5. log in as the newly created user. If at step 4 you are logged in as the user that you created in step 3, the world has finally ended, the milennium has come, and we've got larger things to worry about. ;-) % Anonymous User - Aug. 1, 2002 3:07 pm: I'd note that if I've logged in as Emergency User in a browser, my experience has been that I cannot log in on that browser as a regular user - whether I touch any of the acl_user entries or not. This distinction is otherwise undocumented, and for new users is a sufficient show-stopper to lead many to uninstall Zope if they can't find a clear answer. A quick observation - the answers given in the June 15 and July 3 messages don't work with my system - I need another browser to actually log in as a regular user. From my perspective, if the solutions are this inconsistent, then Zope itself needs design work on this point - urgently. % Anonymous User - Aug. 13, 2002 2:36 am: Windows 2000 user, Netscape 4.7. I hit the Logout button, and Netscape popped an "authenticate" box. I tried logging in here, since that seemed like the obvious thing to do, but received "Authentication Failure". Finally I hit cancel, and Zope gave me the message "You have Logged out". I was then able to log in with the new user. % Anonymous User - Aug. 26, 2002 3:37 pm: "Changing Logins" isn't explicit enough could be interpreted either as "Changing Login Details" or "Login to Another Account" perhaps the latter would be a better title From nobody@nowhere.com Mon Aug 26 21:32:57 2002 From: nobody@nowhere.com (nobody@nowhere.com) Date: Mon, 26 Aug 2002 16:32:57 -0400 Subject: [ZDP] BackTalk to Document The Zope Book (2.5 Edition)/Using Zope Message-ID: A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZopeBook/current/UsingZope.stx#2-24 --------------- The right-hand frame of the management interface shows the object you are currently managing.

XML Documents hold XML content that you can upload, download, and edit with the Zope management interface. You can also script XML Documents using the Internet standard Document Object Model (DOM) API. Zope is much more than an XML repository, since once your XML data is in Zope it can take advantage of all Zope's services such as persistence, security, cataloging, presentation, and more. % Anonymous User - Aug. 26, 2002 6:43 pm: XML Document ? Its not a standard product. After searching the available products on zope.org, i found XML document but it has been superseded by parsedxml. Both of which are still development versions anyway. Sorry, the book was ok until this chapter. Also all the images are missing from this chapter. My advise is dont publish somthing if its not finished, this applies doubly to manuals and help guides.

Because Page Templates are dynamic, you need a way to edit the raw source of the template, unrendered by the page template language. Appending 'source.html' to a Page Template gives you this raw source. Note, if the content-type of your page is 'text/xml' then you'll use 'source.xml', rather than 'source.html'. % Anonymous User - Apr. 22, 2002 2:16 pm: The index_html object is a file not a directory so saving to index_html/source.html doesn't make sense.?.? :\ % Anonymous User - May 29, 2002 5:28 pm: ---Agreed. I find this paragraph totally baffling. % Anonymous User - June 2, 2002 3:05 am: Some HTML editors have a "save to URL" options. (In mozilla composer it is called "Publish As".) The idea is that you provide a URL on the server and the editor uses it to submit your file. true, index_html is not a directory, but neither is "FileLib". Both are just objects in Zopes database and segments of the URL string. Anyway, if you use one of the tools that have this feature, this paragraph should make sense to you. If you don't, don't worry about - just paste the HTML source into the Zope interface! % Anonymous User - June 11, 2002 11:14 am: How about we include a list of "compatible" editors that CAN do this as well as a list of editors that CANNOT do this? it seems you are making assumptions that we all use the same tools you use. % mcdonc - June 15, 2002 11:45 am: Are you going to keep that list current for me? ;-) % Anonymous User - June 20, 2002 10:37 am: Does the name 'source.html' have the special meaning that Zope will use the contents as source, or would any 'XXX.html' work? % Anonymous User - June 24, 2002 10:36 am: did i miss it or did we go over how zope stores files internally already. does the files all being in a database limit you to managing zope using the web interface? % Anonymous User - July 19, 2002 6:15 pm: I agree, very confusing paragraph. Are we HTTP saving/updating index_html (i.e. just saving the changes directly from maya into Zope using HTTP rather than using ZMI?).

A couple suggestions to make it hopefully more clear: 1. Tell us which protocol is being used with this "save to URL" function of your HTML editor. Is it HTTP PUT? Something else? Beats me. 2. Give primary instructions in a non-specific manner (i.e., tell us to use the ZMI first). Then say something like "If your HTML editor supports [protocol], you can use it save to the URL of the index_html Page Template followed by /source.html. % Anonymous User - Aug. 13, 2002 2:52 pm: Hey "mcdonc", at this point we'd like to know ANY editor that works. whether current or old versions! % Anonymous User - Aug. 27, 2002 7:54 pm: This doesn't make any sense with the tools I'm using. In Dreamweaver, you can't upload a file to a file, only a folder. I don't know what the documentation is referring too. What I did discover is that in Dreamweaver, you can name the file the same name as your object and upload it and everything works fine. If the object name is "index_html" then just name your file "index_html" without the dot syntax, and upload the file. Everything works fine. If you look at the object in zope, you will see that it is still a template object and behaves as one.

You should install the tutorial examples before continuing. Choose "Zope Tutorial" from the product add list in the Zope management screen to install the examples. If you have already installed the tutorial, you can either follow along manually, or reinstall the tutorial examples. Note: make sure that you have cookies turned on in your browser. " I've deleted and reinstalled this and still the same. I think it's because the tutorial in my case is installed into something other than the root folder. Somehow the tutorial is looking for things in the root folder and doesn't know where it is installed. This is a show stopping-error which seems really silly.

This may be the container, but varies according to the path through which the script is accessed. Container This is the Folder "Auto Lunch Order", in which this script is located. This doesn't change unless you move the script. If the script is in a ZClass, the Container is the class instance. Remember how we used a DTML method from root in a subfolder? Root would be the container, while the subfolder is the context.

Properties on Property Sheets are exactly like Properties on Zope objects, they have a name, a type, and a value. % Anonymous User - Aug. 31, 2002 2:44 am: If I create a "selection" property, then what is the context in which it searches for the method? Is the context any different between the master class and the instances? Should it be? An example of my problem follows. Create a new ZClass object called "Parrot" in a convenient product folder. Create a method on "Parrot" called "status_list". I suggest a simple Python script will do, such as one that immediately returns a list of strings (like return ["passed on", "ceased to be", ...] etc). Now create a new common instance property sheet for the class, called "properties". In this property sheet, add a property named "status" with a type of "selection" and a value of "status_list". Note that the value appears as "no value for status_list" when added. Now create an instance of "Parrot" somewhere and inspect its properties. Note that the select list is populated with the list of strings returned by the "status_list" method. It seems reasonable to me that you'd want these two cases to behave identically, not differently. In what part of the product folder should such a method/script be placed such that it is equally accessible to the class property sheets and the instance property sheets?

A DTML document is intended to be a fairly complete and autonomous object, whereas a DTML method is primarily intended to be referenced from other objects, providing a means for other objects to use some functionality provided by the method. - To put it in a slightly more advanced way, most of the DTML variables available to a DTML document refer to that document or its properties, whereas the same variables in a DTML method more often refer to the document which is using the method at the time, not the method itself. - Note that at the most basic level DTML documents and methods behave in an identical manner -- it's only when you start doing tricks with DTML markup that the differences become apparent. So which to use? If all you're doing is dishing up static HTML (with or without standard_html_header type substitutions), it really doesn't matter -- indeed, you would do well to consider using a Page Template instead, or even a File if the content is completely static. In other cases the differences described above should guide you: use DTML documents for things which have properties, and DTML methods for things which form a component of something else.
