[Zope-dev] What's 'section' in blocks[0] in block dtml tag?

[Brett Carter]

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...
