You could implement this method on the container itself, but
traditionally such an 'add' method is on the IAdding view for
containers. See zope.app.container.interfaces.IAdding. addforms usually
are views on the adding view (+), not on the container:
The addform then says self.context.add(obj), whereas self.context refers
to the IAdding view. IAdding specifies the add() method you're looking for.
So, you could either register whatever you're doing for the IAdding
view, or you look up IAdding manually somewhere:
adding_view = zapi.getAdapter((folder, request), name="+")
