Hi,
I've run into a really annoying bug and was wondering if it is fixed in the CVS version (I don't have direct internet access to check).
Create a new Product containing a Zclass subclassing from the DTML Document or Method. Add a Python or DTML Method which does:
This document is <dtml-var id>
Then, add an instance of this Zclass. When you VIEW it you get:
This document is <cstring ...>
AND when you edit it the ID is empty. All references to the ID and related internal variables return CSTRING or cause tracebacks. How do i get the REAL id?
Did you try <dtml-var document_id>?
Also, I can get the unprocessed content via self.read() but how do I get the processed data? repr, `..` and index_html all give weird tracebacks.
You have to call yourself with a context or mapping: rendered = self(self) would be an interesting combination if self could satisfy it's own DTML needs.
Just a thought - what about adding a Storage/Zclass mixin class for people doing combo Product / ZClass systems. Hence, the ZClass gets stored within a ZODB in the appropiate Product directory hence reducing installation hassles. This also means we can just zip up the Product directory to automatically include ZClasses [looks at the ZODB experts on Zope-dev].
My brain hurts when I even try to think about it. Without a good model, I have no idea. Give it a whack if you think it can happen. -Michel
