Re: [Zope3-Users] z3c.form and subforms in an AddForm?
Hi again Hermann, Thanks again for replying -- the part that perplexed me was that none of my code was ever mentioned in the trackback -- I wasn't sure how I could be causing zope to recurse at all. It turned out that it couldn't find the form code because z3c.formui's zcml files weren't copied in the package includes directory, so zope kept falling back to my template.pt until it threw a recursion exception. So it was related to a series of other install errors (i didn't have macro installed correctly either, which is what causes the initial recursion error; once macro went in, I started getting adapter errors, which led me to check on formui, which wasn't in correctly either) -- for some reason, when I easy_install Z3C packages, their .zcml files don't end up in my zope skel directory. I finally figured our a bash command to compare all the .zcml files I should have all the ones I actually had. To avoid having such a goofy (and slightly embarrassing problem) in the future, does anyone have any recommendations on a document about getting a sane zope development environment setup? I thought it would be similar to getting my Plone environments set up, but this is obviously a bit different, and I'm no good at debugging the messages I get yet.

The reason was something like calling a function from the template, that again rendered the template, calling the function again and so on, resulting in an endless recursion.

Re: [Zope3-Users] z3c.form and subforms in an AddForm?
Stephan and Hermann, Thank you both so much for all of your help; I can now display my object -- it turned out that my z3c.form had not put its configs in my package-includes, so Stephan's #3 made my display work. Of course, I also fixed some other things that you both suggested, so I know I had other problems. Unfortunately, when I try to use either add or edit, I get the following now: for edit.html I get 127.0.0.1 - - [05/Jul/2007:21:03:22 -0400] "GET /++skin++MovingTargetBrowser/viewguy/edit.html HTTP/1.1" 500 201 "-" "Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4" exceptions.RuntimeError: maximum recursion depth exceeded /opt/zope/zope-3.4.0a1 /lib/python/zope/tal/talinterpreter.py(379)do_startEndTag() -> self.do_startTag(stuff, self.endsep, self.endlen) I pasted the full trackback for edit here: http://paste.plone.org/15590 For addNextAction.html, I get 127.0.0.1 - - [05/Jul/2007:21:04:37 -0400] "GET /++skin++MovingTargetBrowser/viewguy/edit.html HTTP/1.1" 500 201 "-" "Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4" exceptions.RuntimeError: maximum recursion depth exceeded /opt/zope/zope-3.4.0a1 /lib/python/zope/tal/talinterpreter.py(226)StringIO() -> return FasterStringIO() I pasted the full traceback for add here: http://paste.plone.org/15589 The tracebacks are 1600+ lines long, so I'm having a little trouble working my way through them to decipher my error, so if anyone has any idea what I've done wrong or has seen anything similar, I'd be grateful to hear.

Re: [Zope3-Users] Thinking about blog entry structure
Hi Florian, I know that the larger sites (e.g., blogger) use root//MM/title-separated-by-dashes If you expect to support really, really active sites you may want to add Days in there so that it's slightly easier to find an entry. You may also want to support supplemental URLs, such as root/category/NAME so that people can find all of the posts in a given tag easily. I know that lifehacker does something similar. Just as a side note, you should use dashes instead of underscores to separate words in the titles; Google interprets the dash as a space and the underscore as a hyphen (backwards, I know) -- see http://www.movable-type-weblog.com/archive/entry/filename-with-underscore-or-dash.html Good luck!
