RE: [Zope] nested dtml-with

13 Jun 2002

      Ah, lol.. No. Sorry... I must not be making much sense.

I wont explain everything because it would really sound strange. Long
story short, I have a list which is basically the location of a document
(folder, folder2, index_html = folder1.folder.index_html).
...
From a method called from the root of the site: /index_html
I want to basically do the same as this code:

<dtml-with folder 1>
  <dtml-var index_html>
  <dtml-with folder2>
     <dtml-var index_html>
  </dtml-with>
</dtml-with>

But instead using the list. The reason is that every folder may or may
not have an index_html, and any directory that DOES have one in the
traversal path from root to the end of the list (folder1 to
folder2.index_html (3 steps)) will be rendered into the document. 

So I would get something like:

<!-- this is from /folder1/index_html !--/>
<h1>Folder 1</h1>

<!-- this is from /folder1/folder2/index_html !--/>
<h1>Folder2</h1>

The trick is that I am currently in the root namespace. I tried
ascending the tree with the code I pasted earlier, but it seems to just
query all iterations from root, and of course this doesn't work.  

Did I explain any clearer or worse?

Thanks,
Paz

I tried your code out, but subTree('Folder') returns an attribute error

Are you sure that's what it is?
You need to define a Python script called subTree ... see my code
example.

I'd like to be able to call a document from the root of my site based

a list stored in a Session.
You are either talking nonsense, skipping several lines of thought, or I

havn't understood a bit! Was your problem not that you wanted to get a 
list of all objects and subobjects in a folderish object?

Don't do recursion in dtml. It's a cardinal sin, and it will make your 
head explode.
Do it in a Python script instead.
untested::
def subTree(context, type=None):
       """
       Returns the entire sub-branch below this recursively as a flat
list
       """
       children = context.objectValues(type)
       grandChildren = []
       for child in children:
           grandChildren += child.subTree(type)
       return children + grandChildren
