easy tree question

How to hide tree items which do not have a title? As a newbie I still have some problems in understanding when to use objectnames, functions, namespace-prefixes in different DTML attributes. So after going through all the documents about the tree-tag, I could not figure above out via trial&error... What I understand is a) that it has to be a certain expression either in the expr, branches oder branches_expr attribute (but which?) b) it has to be more that just smomething like expr="title", within the tree-tag, because _this_ title in particular is only one specific (the one of the document the tree tag is in) c) To get the title of each iteration-object in the tree, I have to put a function somewhere in the tree-tag, which retrieves the local title of the current tree-object (but I couldn't figure that out.. getattr() or getitem()? what syntax?) Any hints welcome... Oliver .. Oliver Wrede .. owrede(a)khm.de .. Academy of Media Arts, Cologne .. Peter-Welter-Platz 2 . 50676 Koeln, Germany .. http://www.khm.de .. ICQ# 6580315 ..

Is it possible that you need to put the headers and footers inside <TR><TD> </TD></TR> ? Have a look at the HTML source - are the headers and footers in the right place in the source?

DTML-TREE problems -- any experienced arborists out there
by Richard Wackerbarth 16 Feb '00

16 Feb '00

I'm trying to use header/footer to do this and they don't seem to get called in the order I would expect. I have the following structure: Volume 1 Jan 1998 Article 1 Article 2 Feb 1998 Article 3 Article 4 .... Dec 1998 Article 99 Volume 2 Jan 1999 Article 101 ... It's easy to get a "tree" display of the articles. However, I need to stick some text in the middle of the tree. - Volume 1 - Jan 1998 This issue is about snow geese ...... - Article 1 All eggs are not golden. In fact, .... + Article 2 Reader survey ..... + Feb 1998 - Mar 1998 This issue is about racoons ..... + Article 5 + Article 6 Reader survey .... .... Shouldn't be too hard. Put the "About paragraph" in a header and the "Reader survey" in the footer. Then add a little code to distinguish the tree depth so that we only expand headers and footers at the "month" level of the tree. However, this is what I get. Header Volume 1 Header Jan 1998 Header Article 1 Footer Article 1 Footer Jan 1998 Header Mar 1998 ... Footer Volume 1 Footer Animal Matters - Volume 1 - Jan 1998 - Article 1 All eggs are not golden. In fact, .... + Article 2 + Feb 1998 - Mar 1998 + Article 5 + Article 6 ALL the headers and footers are processed BEFORE any of the tree is rendered. Anyone got any insights? -- Richard Wackerbarth rkw(a)Dataplex.NET

Creating a menu for each page
by Roddy 16 Feb '00

16 Feb '00

I'm quite new to Zope and have been trying to migrate a site from a bunch of Java servlets to it but am getting bogged down trying to get a handle on DTML. The DTML guide isn't exactly helpful since it jumps straight into it without giving many examples. Anyway, the problem! I've been trying to find the answer in the documentation (how-to's and tips etc.) but can't quite do what I need to do. I have a site that is probably going to get very complex but stems from about 5 main sections. I have my main sections as links on the header to be used all over the site so I don't need to provide an extra menu containing them, but I do need to create a sub menu once inside each of the sections. So if I have the following site structure: Root Section1 Section1.1 Section1.1.1 Section1.1.1.1 .... Section1.1.2 Section1.1.3 Section1.2 Section1.3 Section1.4 Section2 Section3 Section4 You get the idea... If I enter section 1 then I get a menu on the side of the page that will look like the following: Section1 Section1.1 <-- link Section1.2 <-- link Section1.3 <-- link Section1.4 <-- link (ie: it has a title of the section followed by links to each of the sub-sections) Once I'm in a Section1.1 I would get: Section1 Section1.1 <-- link (bold) Section1.1.1 <-- link Section1.1.2 <-- link Section1.1.3 <-- link Section1.2 <-- link Section1.3 <-- link Section1.4 <-- link Then once in Section 1.1.1 I would get: Section1 Section1.1 <-- link (bold) Section1.1.1 <-- link (bold) Section1.1.2 <-- link Section1.1.3 <-- link Section1.2 <-- link Section1.3 <-- link Section1.4 <-- link (ie: I get no more of the structure in the menu, only the first 3 levels). So, I need to be able to create this tree from anywhere in the site, this will probably be in my global standard_html_header so it needs to work all around. I have my folders all setup to try and get this to work but I just can't get enough of the information I need and acquisition is driving me nuts! (I can't just be a _normal programmer_, I have to worry about variables all the way up the tree!) A complication is also that I would like it to be able to determine the root folder of the site, not the root folder of the instalation. That is, so it will work even if I have '/Zope/' at the start of the URL or if I move the whole thing down into itself (not sure why I would do this, but you never know!). I have tried putting a 'property' in the top to indicate that's the root folder but acquisition causes this property to be accessable all the way down so if I test for it it's always there (growl). I have figured out that I need to be using the <dtml-in PARENTS> and have been using that to try and get what I want but this seems too complicated for a beginner and I need help! I imagine that when I start to get a bit more of a handle on DTML then things will become a little more easy but right now I'm wondering if I'm doing the right thing by moving to Zope. Any help would be greatly appreciated!

Using Zope with a third party provider
by Kurt Beyer 16 Feb '00

16 Feb '00

Hello All! I intend to put up my web-page using Zope but my provider refuses to install Zope and grant me access to it. So, this is my question: a) Is it possible to treat the Zope-Process as "normal CGI"? b) If so, what has my provider to do with it? c) If none, is it enough to just install the complete Zope distribution within my home-folder on my prodvider's server? Thanks for any help! Regards, Kurt.

Hi! I have a problem when I try to edit a dtml-document with the edit form in Netscape running on WinNT or Win98. If the document is too big, I can only delete characters but not type anything in. It's no problem using Internet Explorer or from any UNIX machine. Frederik Ferner

Re: [Zope] Is this a bug with multiple selection lists?
by Michael Halle 16 Feb '00

16 Feb '00

This problem *isn't* fixed in the latest release. Here's a patch to fix it (I submitted it to the Collector). In addition, if you render your own multiple selection lists, you need to check to make sure the value of your property isn't None when deciding what to select.

Zope versions and Emacs
by Petr Knapek 16 Feb '00

16 Feb '00

Zopists, I have any problem with Zope versions when I edit my DTML code in Emacs and update it through FTP access. I see no indication (red diamond) of such a way changed DTML method (or other object) and the version tells me, that there is no change in this version. But, on the other hand, I can see this change in the UNDO Zope tab. Does anyone know more about this? I prefer to edit DTML code in Emacs and not in web interface, where there is no problem with Zope versions. -- Petr Knápek PVT.NET, e-mail: petr.knapek(a)pvt.net, tel:+420-5-41 558 394 PVT a.s. - pvt.net, Veveří 102, 659 10 Brno, Czech Republic
