I'm sure this is a newbie question, so go easy on me :) Anyway, I've finally gotten around to mocking up the python.org website in Zope. I saw some neat code called Breadcrumbs which includes a list of parent links to the page you're sitting on, e.g. Home > Community > On-line PSA Registration Naturally, I modified the DTML to do things a little differently, and one of the things I want to do is to be able to add title abbreviations (i.e. nicknames) to some folders, using them in preference to title or id (I want a sort of nickname_or_title_or_id method). So the idea is to add a property to some folders called `nickname' and use that if it exists, otherwise use the title_or_id. The problem of course is that I do not want `nickname' to be acquired. I figured I could write DMTL like the following to accomplish this: -------------------- snip snip -------------------- <dtml-with folderobj only> <dtml-if nickname><dtml-var nickname> <dtml-else><dtml-var title_or_id> </dtml-else> </dtml-with> -------------------- snip snip --------------------
From the docs, it seems that the `only' tag should stop the name search in enclosing namespaces, but this doesn't seem to work. In my root folder, I include a nickname property, and set it to "Home". In a subfolder (say "psa") I do not have a nickname property, but this DTML method is returning "Home" for both folder objects.
I've also tried substituting the dtml-if test with something like <dtml-if "_.hasattr(folderobj, 'nickname')"> but that didn't seem to make a difference. Is this enough information to help? I'm sure I'm either misunderstanding some simple concept or doing some dumb newbie lose. Any help will be appreciated. Thanks, -Barry
