This method accepts an object in which it will look up values to insert in
the dtml file, and a mapping object (dictionary) that also will look up
values to insert.
So i guess that is what (None,md) does.
But I dont understand what "ignored" does in my method, as it is unused,
unless it is used by md
Nope, ignored is the client, which you don't need to worry about.
def test(self,ignored,md):
Furthermore I dont understand what md is. Some kind of mapping object
naturally, but where does it come from?
pDocumentTemplate.py has one implementation of it.
it's a stack of dictionaries, basically... When you do md['key'], it
looks for key in the top dictionary, then in the next one down, then in
the one below that, etc, and only throws a key error if one can't be
found at all...
Also what is testisDocTemp supposed to do?
This is a bit of ExtensionClass wierdness. Think of it has "give the
test object the 'isDocTemp' attribute".
If I grep the source a "isDocTemp" shows up but is isn't easy to see what
this does either.
If some arcane bit of Zope's calling machinery finds this (probably in
BaseRequest.py) it sends different parameters to __call__.
HTH,
