[Zope-dev] url traversal
I have the classic problem of wanting my method 'foo' to work like: http://localhost/foo/a/b/c where a,b,c are parameters passed to foo. I've found some info in the mailing list archives, namely: http://lists.zope.org/pipermail/zope-dev/2000-May/005197.html Has the 'Traversal' interface been implemented? What are the specifics of implementing something like I describe above?

[Zope-dev] Publishable Objects...
What does it take to make an object publishable from an ExternalMethod? I.E., I have a class (see bottom of message) that does some url traversal trickery, that works from a python product. Shouldn't I be able to just stick it in an External method, and just return it, i.e.: def returnme(self): return MyClass() and it get's published as normal? The problem is, __bobo_traverse__ never gets called on MyClass when it's in the external method. It works fine from a python product though. -Brett ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] dtml-in performance
What can I do to maximize the peformance of a dtml-in statement? When iterating over a 2000 row database query, it takes about 20 seconds - time mostly spent doing security checks, and calling __getitem__ in DT_InSV.py. Is the performance of dtml-in just slow? -Brett ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] What's 'section' in blocks[0] in block dtml tag?
Lee, I've been diddling around with the same stuff. It took me a lot of introspection with printing of errors via MrCreosote/Spew. To answer your question, 'section' is an object which contains an attribute 'blocks'. If you want to render the dtml in there, you can run the 'render_blocks' method in 'zope-instance/lib/Python/pDocumentTemplate.py' You pass it the section.blocks object and a mapping dictionary which is the current namespace stack that gets passed in as the only argument to the 'render' method in you tag definition. If you just want the raw text, check you the render_blocks method, so you can see how they take apart the 'section.blocks' object. As to the object hiarchy of everything, your guess is as good as mine as to why there's a list of tuples of blocks wrapped in a section object, wrapped in another blocks object, I have know idea. Perhaps the designer of the document templates could answer... -Brett "LEE" == LEE Kwan Soo [EMAIL PROTECTED] writes: LEE Hi. I'm playing/struggling to make a custom block dtml tag.

The namespace just reflects the attributes of the current object, plus
whatever other tags push onto that stack (such as the in tag, which pushes
the current element of the list it iterates over on top).
If you retrieve the 'this' method from the stack, and call it, it'll
return the topmost object on the stack. It is implemented in
