[Zope] Calling Python script from ZPT - Solution

[Bart Hubbard]

Whoops!  Good point.  I had edited my question many times w/o changing the title.  My real situation is a little more
complex than the question I'd posed.  What I'm really doing is trying to do in ZPT what I was doing in a DTML doc.  I
also wanted to clean up my design by moving the logic to my script.

My script finds an object fine, but I couldn't get it to execute a method properly that the object contained.  Thanks to
Peter Sabaini's hint, I have it working now.  I now have the script explicitly setting the context before attempting to
execute the method.  The updated test script now works great, and is (no error handling in there, yet):

  import random

  # Get content catalog and search for an object using the args
  # and the current date/time
  zcat = context.content.Catalog
  results = zcat(category=findCat, meta_type=findType, publishDateRange=DateTime())

  # Pick one content object at random
  item = random.choice(results).getObject()

  # Prepare to call the view method on the content object
  dtml_method = item.view
  REQUEST = context.REQUEST

  # Call the method in the context of that item and return the results
  retVal = dtml_method(client=item, REQUEST=REQUEST)

  return retVal

Next I plan to allow various 'views' to be requested from the script based on an argument, as well.  Then I'll have a
good script to use in my ZPTs to request the various types of content I have indexed.

Thanks for the help,
bart
