[Zope] Re: Dynamically Accessing Folders

[James W. Howe]

Thanks to all who helped me with my question about how to dynamically 
iterate over subfolders  in order to invoke a method in each of the 
subfolders.  I have one more thing that I want to be able to do with this 
code.  I currently have a structure which is something like this:

Folder A
	iterate (DTMLMethod)
	Folder B
		myName (DTMLMethod)
	Folder C
		myName (DTMLMethod)

At the present time, no matter where I invoke the "iterate" method, I get a 
list of the results of invoking "myName" for Folders B and C.  What I want 
to be able to do is tailor the results depending on were the iterate method 
was invoked.  For example, if I invoke the method from 
http://localhost/FolderA/FolderB/iterate the results might be:

Folder B - I'm selected!
Folder C

but if I invoke it from Folder C the results might be:

Folder B
Folder C - Pick from below:
	Item1
	Item2

What I would like to be able to do is invoke "myName" with a parameter 
which would indicate who is the invoker of "iterate".  The pseudo-code for 
"myName" might be something like:

<dtml-if sender = ??myself??>
	<dtml-var fullContents>
<dtml-else>
	<dtml-var simpleContents>
<dtml-endif>

The "iterate" DTMLMethod (defined in FolderA) would be defined loosely as 
follows:

<dtml-with FolderA>
	<dtml-in "objectValues(['Folder'])">
		<dtml-var "myName(sender=???)">
	</dtml-in>
</dtml-with>

What I'm trying to do is create a set of methods which reside up at the 
"FolderA" level and where the subfolders only have to implement the 
"fullContents" and "simpleContents" DTML Methods.

Is there a way for me to do this?

Thanks.
