objectItems() question
by Ben.Peter＠t-online.de 16 Apr '01

16 Apr '01

Hello all, I am utterly confused: The following piece of dtml in standard_html_header <dtml-in "objectItems()"> <a href="<dtml-var absolute_url>"><dtml-var title></a> <dtml-unless sequence-end><br> </dtml-unless> <dtml-else>No items. </dtml-in> will yield a complete list of objects in the current container if there is a DTML Method 'index_html' available. If that is not the case, it will print 'No items.', even if there is a DTML Document index_html and any number of other Items, like folders. Is this intentional or (which I believe it'll turn out to be) am I blind again? Thanks for your help, Ben -- Ben Peter - Feldstrasse 8 - 35091 Coelbe Ben.Peter(a)t-online.de ph: (+49) 6421 983520

Filter Export
by Tim Cook 16 Apr '01

16 Apr '01

Has anyone tried to filter .zexp files to only contain a specific meta-type? For example: I have an application with instances of MyMetaType ZClasses in a folder. MyMetaType's are containers. I want to only export the MyMetaType objects AND everything they contain. Would I have to build a complete export module for this (that's what I'm guessing)? -- Tim Cook, President - FreePM,Inc. http://www.FreePM.com Office: (731) 884-4126 ONLINE DEMO: http://www.freepm.org:8080/FreePM

Calling dtml method from search result
by Byron C. Servies 16 Apr '01

16 Apr '01

Hi there! How do I call a DTML method that I have acquired as a result of a ZCatalog search? I can get the path to the method from the catalog, but I cannot figure out how to actually call the method and put the output in the output for the results page. I'm certain this is a common question, but I seem incapable of finding anything on zope.org, in the zope book, or in the mail list archives on the subject. A pointer, please? Thanks from a newbie, Byron

Re: [Zope] Cobalt cubes and Zope
by Luciano Ramalho 16 Apr '01

16 Apr '01

We bought a Cube 1 in 1998, and we did use Zope on it for a while, until Zope started requiring Python 1.5.2 compiled with threads. We never managed to compile that in our Cube, and the key drawback of that first generation was the lack of support for upgrading the OS. AFAIK, newer Cubes make it easier to upgrade the OS. The real test is this: can you compile Python 1.5.2 (and now Python 2.1) on it? Once that is solved, the rest is easy. Regards, Luciano Ramalho CURTIS David wrote: > > Hi, > > I was wondering if Cobalt and Zope are compatible. I may wish to run my Zope application on a Cobalt cube but it currently is not configured to run Zope. It comes pre-installed with Apaches 1.3. Any known issues? Perhaps there is a company that provides a turnkey zope+Apache solution. Also, I'm sure that is is possible to run multiple sessions of Zope. Can someone direct me to where this information is kep.

acquisition / dtml-with problem
by Paul Winkler 16 Apr '01

16 Apr '01

OK, I have a dtml document called "Foo". This works fine when I view the document. Now let's say this document is in the folder called FooFolder in which there is a folder called SubFolder. Now I can call Foo_dtml as either FooFolder/Foo_dtml, or as FooFolder/SubFolder/Foo_dtml through the magic of acquisition. No problem so far, all is good. Here's the problem. If I put this code in Foo_dtml: <dtml-with images> <dtml-var izea-sundial.jpeg> </dtml-with> ... it works fine when called as FooFolder/Foo_dtml but NOT when called as FooFolder/SubFolder/Foo_dtml . WHen I do the latter, I get this: Traceback (innermost last): (SNIP) File /home/pw/Downloads/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, /home/pw/Downloads/Zope-2.2.2-src/lib/python/DocumentTemplate/DT_With.py, line 132, in render (Object: images) AttributeError: (see above) Why? It seems like dtml-with is unable to find my images folder?? -- ................... paul winkler .................... custom calendars & printing: http://www.calendargalaxy.com A member of ARMS: http://www.reacharms.com home page: http://www.slinkp.com

presenting a list of stuff [2]
by Sven Fischer 16 Apr '01

16 Apr '01

hello (again), i want to display rows of content with alterning colors (one white row, one grey row) but my content isn't always there (i have an if around those tr tags) : ItemA (grey) ItemB (white) ItemD (grey) ItemE (white) ItemC is empty i thin i have to look at item_sequence, but since it's not really a sequence (just stuff (text properties) that i want to make look like one) it doesn't work out of the box. maybe assigning a variable at the begining and counting the loops (ugly, i might as well code this in asp ;-) ? any ideas ? $ven
