Hi,

I have the follow = situation:

a folder with 19 = images

a page template that display the images = inside a=20 table. I want to put 5 images in a row.

I try this:

<table width=3D"100%" border=3D"0" = cellspacing=3D"0"=20 cellpadding=3D"0">
<tr tal:repeat=3D"thumb=20 python:here.conteudo.objectValues('Image')" tal:omit-tag=3D"python:p= ath('repeat/thumb/index')%5!=3D0">
=20 <td><img src=3D"/images/papel/campeonato.jpg" width=3D= "100"=20 height=3D"75" tal:replace=3D"structure thumb"></td> =

</tr>

</table>

but omit-tag remove the = start AND the end=20 tr when the condition is true and my page display 4 rows (one with 1 = image, 1=20 with 4 images, 1 with 1 image and 1 with 4 images). I tried with = tal:condition=20 to, but I can=B4t do what I want. Can I control the start OR the = end=20 tag?

I suspect that most editing tools won't much care what comes after the 'tal:', here, so you could equally well use 'tal:block' or 'tal:feezba'. Now that I think about it, this has the additional advantage that the ZPT parser won't try to validate the block vs. inline-ness of this sort of tag, so you won't have to decide between 'div' and 'span'.

We are also seeing this speed problem. We've taken to disabling PT cooking in a lot of places (most times, the page is now cooked when a user requests it the first time). We've got about 8 folders of 10 templates, and that's going to grow considerably over time. Even cooking just one folder of 10 templates of around 10-15kb each takes quite a while on a "slow" processor (500Mhz x86 or slower). One of our outstanding issues is to figure how to not cook uncooked PTs when users delete folders of them :) Richard From steve@spvi.com Thu Aug 16 05:01:28 2001 From: steve@spvi.com (Steve Spicklemire) Date: Wed, 15 Aug 2001 23:01:28 -0500 Subject: [ZPT] Strange permission error with the new release..

Cooking essentially means parsing the template and transforming it into an internal object. The current ZPT implementation performs cooking immediately when the ZPT is loaded from the ZODB. This may become a problem, as cooking may take a long time. For example, if you have a folder with lots of ZPT's and the folder get displays in the left frame of the ZMI for the first time, then all contained ZPT's are loaded. It can take minutes before the tree display is finally build. There is a patch (ZPT - delay cooking) at URL:http://www.dieter.handshake.de/pyprojects/zope that delays cooking until the ZPT is actually used for something. This speeds up initial operations considerably.

In this particular case, you probably should be using the Zope 'DateTime' class instead of the Python 'time' module. It has a lot of date and time formatting options, and is available in Page Templates either through the path "modules/DateTime/DateTime" or directly in Python expressions as "DateTime", for example: "python:DateTime().Date()". In general, when you want to expose modules to restricted code, you're best off creating your own Product (just a subdirectory of the Products directory with an __init__.py) called something like "myModuleSecurity" and placing the security calls in that.

Now after upgrading to 1.4 I find that I can't call manage_changeProperties from within a ZPT. I have a ZPT named 'Edit' in the ZClasses Methods folder. I looks like this:

However, I don't need the whole template to know what I'm doing on each page, so expanding doesn't buy me anything. In fact, it adds a large amount of clutter when I try to modify the pages through the Web. I found that I can default this to off by changing 'expand = 0' in the product, but I have to remember to do this every time I upgrade. I don't believe there's a way to "unexpand" (perhaps because it's not possible?), so I end up having to go back and clean up the expansion if I forget to turn it off. This is minor but sufficiently annoying. Is there something non-hackish I can do to keep this feature off through upgrades? Thanks! _______________________ Ron Bickers Logic Etc, Inc.

I already have a to-do item to make expansion/unexpansion more useful and regular. This includes: - When a template is unexpanded, use-macro bodies should be "stripped". This means omitting the contents of used macros, apart from filled slots. - There should be a way to remember (cookie?) which state you prefer, without hardcoding it.

I've often thought about how nice it might be to have some special place in the Zope tree to assign defaults for different products. Like a registry, I suppose. I have several products where I wish defaults were different but they're hard coded in the product. The products would have to support it, of course, but it would be easier than, say, every product creating an "add" form that has a bunch of options with the defaults filled in. Is this a worthy suggestion for the collector? _______________________ Ron Bickers Logic Etc, Inc.

I'm not familiar enough with the new Component Architecture to know how it would cure the problem.

No one is :-/ It's a work in progress, but one of its concepts runs like this: The Zope root contains a Service Manager. There is a way to create subfolders that have Service Managers, too. When you visit an SM, one of the things you can do there is install a "Package". This will add "Components" and "Services" to the SM. (Why the scare quotes? Because these things aren't well defined yet). You can then configure these things, and they will be available within that part of the site (the whole site, if it's the root SM). Some "Services" are "Factories", which allow you to create objects. So, in this future world, you would go to your site's Service Manager, install the ZPT Package there, then configure the "Page Template" Factory to set 'expand' off in new instances. Maybe.

Sounds nice. Does this mean that we may be able to define ZClasses that are only available within a particular part of the site? That would be very useful, esp. for some virtual hosting setups. > So, in this future world, you would go to your site's Service Manager, > install the ZPT Package there, then configure the "Page Template" > Factory to set 'expand' off in new instances. Maybe. I look forward to it. In the mean time, I'll change expand to 0 and wait for a ZPT setCookie to save the day. Thanks! _______________________ Ron Bickers Logic Etc, Inc.

WebDAV clients don't take dynamic pages into account, and send a simple HTTP GET to load them. This gets you the rendered HTML. The z2.py start script has a "-W " argument that you can use to set up a WebDAV source port. For instance, if you add "-W 9800", Zope will send page source in response to GET requests on port #9800. You should only use WebDAV with a source port. Also, there's an issue to beware of when using a "make WebDAV server look like a mapped drive" products such as WebDrive and WebIFS. Since web page editors think that they are editing a local file, they will often perform operations that work well with a filesystem but screw up an object database. For instance, when Dreamweaver saves changes, it will create a temporary file, rename the original file, rename the temporary file into place, then delete the original file. This destroys all properties, history, and security settings of the page.

The problem isn't with DreamWeaver, but with the combination of DreamWeaver and WebDrive. If you use DreamWeaver's native WebDAV support, checking files in and out of Zope, you'll be fine. Any tool that makes an object database look like a filesystem, as WebDrive and WebIFS do, is deceptively helpful and potential trouble. Zope objects are not files, and Folders are not directories.

Should it? Message-ID: <0108300128470G.00404@subterraneans> I've been playing around with HTML tidy[1], using it to test some page=20 templates that are part of a skin for a CMF product I've written. The -as= xml=20 flag is very useful for finding non-xhtml compliance problems in the=20 templates, and various other goodies (you're not suppose to use a span in= side=20 a select, for example so you have to use optgroup, but they mess up the=20 rendering in konqueror from kde 2.1...).

Let me rephrase that :-) If HTML attributes are case insensitive, then=20 tal:attributes should replace attributes in a case insensitive fashion ie= =20 they should replace 'onchange' with 'onChange' if that's what you asked for.

Thanks for that. Macros now work if the outer page is passed as an option when the inner page is called. I thought I would try again and see whether it was now possible to refer to the outer page from within the inner page via 'container', but without avail. Presumably this is because container is normally a Zope folder (rather than a filesystem folder) and so is only defined in a Zope environment (I'm guessing by ZopePageTemplate). When calling a template outside Zope, is there some kind of object with the necessary behaviour that could be passed as a 'container' option?

We have almost completely ditched DTML in favor of Page Templates, but as long as it is not possible to create proper XHTML with them , i consider them partially broken. hmm.. i actually think XHTML should be the default these days, with a "pre-html4.01-mode" for those going old-style.... :-) Wednesday, August 29, 2001, 15:28:47, you wrote: JM> I've been playing around with HTML tidy[1], using it to test some page JM> templates that are part of a skin for a CMF product I've written.

Message-ID: <01b201c13131$f5146e80$5c773fc1@ml.uwcm.ac.uk> All, After reading the docs, and not finding anything, my question is this: How do you create a tal:repeat with the same functionality as a dtml-in with skip_unauthorized? I know I could create a Python Script that emulates this, I'm just wondering if there is anything that automatically gives you this functionality? tia Phil From tol@tanghus.dk Thu Aug 30 10:14:15 2001 From: tol@tanghus.dk (Thomas Olsen) Date: Thu, 30 Aug 2001 11:14:15 +0200 Subject: [ZPT] skip_unauthorized?

You would need to write one, although it could be as simple as: class FSPageTemplateFolder: def __init__(self, basepath): self._basepath = basepath def __getitem__(self, name): fn = os.path.join(self._basepath, name) if os.path.isdir(fn): return FSPageTemplateFolder(fn) txt = open(fn).read() pt = PageTemplate() pt.write(txt) return pt This is horribly inefficient, but it's a start.

I realize it is actually a deep topic and one that is probably an ongoing dilemma since there isn't an easy answer on finding the most real-world practical approach to the separation of presentation, logic and content. I thought this was well expressed earlier this week by Andrew Saywer when he said on "Re-working Breadcrumbs" We talk about this sometimes here at ZC as well. I'm drawn to both sides, I like clean, clear code, but my problem has been that if we pull all the logic out into scripts, there is a level of 'disorderliness' (for lack of a better term) which follows; there is a diminishing point of return trying to follow code when what makes up a single page is actually found in a zpt template, a couple objects which fill slots on the template, and a dozen various python scripts scattered about those pages which make up the various logic required for a page rendering. I don't know what the solution is, but I'm sure it's not the blanket approach or stripping as much logic as possible out into python scripts. I see our skins growing and growing to unmanageable levels possibly. Andrew Nevertheless, I believe what would be best for me is to proceed with trying to make a custom CMF object/type that is CMF enough to take advantage of the cataloging in the same way as more basic CMF objects like CMFDocument, but is based on ZPT (PageTemplate) enough that I can put in some ZPT in the "content". However, being the newbie that I am to CMF and ZPT and Zope (although not python), I would really appreciate all guidance on how to go about this. I know how to make new Products but I suspect there could be alot of gotchas involved with trying to use ZPT as a base, that the ZPT guru's could better predict that me. Has anyone had a need for this kind of thing or think it would be useful? Has anyone already implemented something like it they could share with me? Essentially, php, jsp, dtml, all let you throw in logic in what should be mostly presentation, and while it CAN be abused, it can also be SUPER practical to have this ability and it can sometimes be even cleaner than having the tons of small fragments of logic elsewhere (like Andrew alluded to) just because you can't mix a little in your presentation or content. Hope I'll get some feedback, ideas, practical how to steps, etc. It will be most appreciated. Thanks, Lynn P.S. I hesitated on cross posting as I don't want to annoy those who are on both lists, but I felt like it applied to both lists and there might be some people on only one or the other who could have input or have the same dilemma, and I wanted to catch all I could. : ) From mail@peterbe.com Fri Aug 31 08:19:11 2001 From: mail@peterbe.com (Peter Bengtsson) Date: Fri, 31 Aug 2001 09:19:11 +0200 Subject: [ZPT] skip_unauthorized?

Message-ID: <032401c13200$62543880$5c773fc1@ml.uwcm.ac.uk> All, Since one of the goals of the ZPT project is to faciliate the separation of presentational and functional layers, I have a small question. What is the recommended way of calling a method that has no return value, and has no impact on the presentation of the page in question? For example, page1.html is a form that lists objects with a check box to mark for some action. Page 2.html then takes those selected and for example deletes them. Assuming that when successful there is no return value (other than the default Python return of None). How would this be called to ensure that it has no side-effects in the Page Template itself. Am I making myself clear? Not sure, but I hope you'll get my train of thought. The only way I can see of doing it is something like, This should leave no trace in the output, but the actions should be taken. Am I right/ Thanks for listening to my drivel.

Offhand, tal:define="ignored python:here.call_me(foo=1)" seems fine. > Page 2.html then takes those selected and for example deletes them. I don't use this pattern. The target of my forms is always a script. The script performs validity/sanity checking on the input, then either returns a template asking for corrections or performs the request action and redirects to the "next" page. Cheers, Evan @ Zope
