[Zope-CMF] Moving CMF product from DTML to ZPT
Wed, 12 Feb 2003 11:44:50 -0500
Well, I managed to create a simple Product that implements a new CMF
content type for multilingual documents. I used DTML for the skin data,
because that's what I knew (and because that's what CMFBoringProduct
uses, and I was using it as an example).
Seems like the modern thing to do, of course, is use page templates, so
I sat down and RTFM'd yesterday, and now I'm trying to convert my DTML
skin to ZPT. Here's what I had before starting the conversion:
(LocDublinCore.py is a copy of Rainer Thaden's LocDefaultDublinCore.py,
renamed and slightly tweaked.)
Here's the skin layout I'm moving towards:
I managed to get the view PT sort-of working -- it doesn't crash, at
least. But the edit_form PT is broken and I'm quite mystified; here's
the traceback I get when I try to edit an instance of MLDocument:
Traceback (innermost last):
* Module ZPublisher.Publish, line 98, in publish
* Module ZPublisher.mapply, line 56, in mapply
Yes, that's all there is -- probably the shortest Zope traceback on
record. From reading the code in ZPublisher/mapply.py, it looks as
though some object somewhere has an 'im_func' attribute but no
'func_code' attribute -- but mapply() assumes the presence of 'im_func'
implies the presence of 'func_code'. Apparently something I've done is
violating some low-level assumption in Zope -- but how?!? Anyone have a
clue what's going on here?
