[Zope] DTML Doc and Python scripts and aq_parent

[Chris Kratz]

Hello all,

I'm trying to wrap my head around acquisition once again.  Each time I think
I get it, another curve ball gets me.  If anyone has any pointers I would
appreciate it.

I have the following structure:

Root
 + FolderA
     + Folder A1
          DTML_Doc w "Really Nifty Title"
  + CommonStuff
      + PythonScript

inside of DTML_Doc, there are several lines of code that look something like
this:

<dtml-with CommonStuff>
  <dtml-var PythonScript>
</dtml-with>

In the python script I have the following

print context.title                                 # Prints 'PythonScript'
print context.aq_parent.title                 # Prints 'CommonStuff'
print context.aq_parent.aq_parent.title #  Prints Folder A1  ???Huh???

I think I understand the reason you get FolderA1s title attribute because it
is the container of DTML_Doc and thus is the aq_parent of CommonStuff in the
namespace.  But, then how does one pull attributes such as the title from
the caller which in this case is a DTML_Doc?  How does one get a handle on
the object that called a script?  Any ideas?
