object.some_set.all().delete() does not call the delete method on some object

[gert@…]

If you override an objects delete method:

object.something_set.all().delete()

does not do the same as:

for something in object.something_set.all():

something.delete()

The new delete method is never called and hence any associated cleanup or audit code are never called. This comes to light when you delete an object which in turn deletes related objects.
