[Zope] Classes

[Shalabh Chaturvedi]

I think I understand what you want. And I have it solved!

There is a hook provided by Zope for such a thing. It's called manage_afterAdd.
Whenever any object is added to a container, the manage_afterAdd method of the
_object_ is called with some parameters.  What you can do is define an external
method called manage_afterAdd in the 'methods' tab of your ZClass:

Define the function like so:

def manage_afterAdd(self,item,container):
    item.myparent=container.id
    return

I have this working here, so its tested. Now, the myparent property of any
object I create or move is always the id of the folder it is in.

Hope this helps,
Shalabh
