[Zope] returning a dtml variable from a python expression

[Thomas B. Passin]

DTML Rule # 1 - No DTML within DTML

So you can't say

<dtml-call expr="manage_addProduct['Photo'].manage_addPhotoFolder(id =
'<dtml-var id>', title= '' )">

but you don't need to, since you can say

<dtml-call expr="manage_addProduct['Photo'].manage_addPhotoFolder(id = id,
title= '' )">

Remember, the DTML value is NOT named <dtml-var id> (as you put it), the
"dtml-var" is just there to render it (write it into the resulting
document).  The name of the variable is just "id".

Wouldn't an attribute called "id" collide with normal id properties?  Better
to call it something else, I would think.  If it's coming from an sql query
you can call it pretty near anything you like.

A simple question
I have a variable that is returned from an sql query as <dtml-var id>
I wish to include this in a python expression to create a photofolder or
photoimage.
When used as
<dtml-call
expr="manage_addProduct['Photo'].manage_addPhotoFolder(id='12345',
title='')">
this works.
but if used within
<dtml-in createfolder size=50 start=query_start>
<dtml-call expr="manage_addProduct['Photo'].manage_addPhotoFolder(id =
'<dtml-var id>', title= '' )">
</dtml-in>

I get
Error Type: AttributeError
Error Value: _setObject
File C:\Program Files\WebSite\lib\python\DocumentTemplate\DT_Util.py, line
230, in eval
    (Object: manage_addProduct['Photo'].manage_addPhotoFolder(id =
'<dtml-var id>', title= '' ))
    (Info: manage_addProduct)
  File <string>, line 2, in f
    (Object: guarded_getitem)

What is the correct way to do this?
Thanks for any help
