[Zope] getting parent in product

[Christopher N. Deckard]

Hello,
I've written a ZMI configurable PutFactory Product to allow our
users to be able to configure what types of objects are created when
files are PUT using WebDav.  What I would like to add is the ability
to call a script immediately after the object is created.  The
script could do things like auto-catalog images in a ZCatalog or
send out an email every time a file is uploaded.

Looking at the code in webdav/NullResource.py NullResources.PUT():

      ob = (factory(name, typ, body) or
            self._default_PUT_factory(name, typ, body)
            )
      # We call _verifyObjectPaste with verify_src=0, to see if the 
      # user can create this type of object (and we don't need to   
      # check the clipboard.        
      try:
          parent._verifyObjectPaste(ob.__of__(parent), 0)
      except Unauthorized:
          raise
      except:
          raise 'Forbidden', sys.exc_info()[1]
                                                                    
      # Delegate actual PUT handling to the new object.
      ob.PUT(REQUEST, RESPONSE)
      self.__parent__._setObject(name, ob)
                                                                    
      RESPONSE.setStatus(201)

it doesn't look like I can do what I'd like to do without overriding
NullResource.PUT().  Any thoughts on how to accomplish this?  

Thanks,
-Chris
