Is myobject a DTMLMethod? Some kind of container?
Sorry... a good example for myobject would be a DTML Document.
I don't see how it can contain a var tag if it's not DTML. If it is DTML, I don't see where mynavigator fits in.
It is DTML, containing the line <dtml-var standard_html_header> standard_html_header is a DTML Method containing <dtml-var mynavigator> mynavigator is an object of meta_type 'Navigator' and it's the __call__ method of the Navigator product that I'm having trouble writing :-S
So, if I give my product a class attribute of isDocTemp=1, what signature should I give my product's __call__ method so it picks up the DTML namespace?
def __call__(self, ignored, md): ...
This, of coruse, begs the question as to what 'ignored' is, but I probably don't want to know ;-)
No: self.nav_header(None, md)
ok..
In any case, what is self in __call__(self, ...) and what should it be in nav_header(self, ...)?
Python method signatures always begin with an argument that is the instance to which they are bound.
Okay, so in the __call__ case, self will be the mynavigator object? Anyway, the isDocTemp thing seems to be getting somewhere. md is a TemplateDict, and that's a stack of InstanceDict's, right? Now, from what I've seen from playing, the object I've been looking for all along is the one whose InstanceDict is on the top of the md stack. So, two questions: 1. How can I get the top most InstanceDict out of md? is _pop the only way? If so, I would guess I do: x = md._pop(1) md._push(x) to get the InstanceDict without disturting the namespace stack? 2. How would I turn the InstanceDict, x, back into an object? From reading pDocumentTemplate.py, I would guess: obj = x.self Is that right? well, thanks for all the help, I _think_ the end is in sight now ;-) cheers, Chris PS: Once I've got that object, can I still use aq_chain(obj,1) to get the list of obj and its containing parents? (In essence, the PARENTS'y type thing I've been looking for all along ;-)
