[Zope-dev] Detecting object deletions

[Robert Leftwich]

How do I detect if an object is being deleted ?
I need to detect when an object is being deleted in order to perform some clean up.

The deal is (excuse the highly imaginative names) :

Foo inherits from Bar which inherits from Folder
Foo has a __del__ method which prints 'Foo is being deleted'
When an instance of Foo is deleted (via manage_delObjects) I would expect __del__ to be called at some point but nothing happens.

Am I overlooking something obvious ?

Thanks
