Thanks Michael, I managed to get 2. to work.. However I was now thinking it may be simpler to create a new relation 'grandchildren' on the grandparent.. and add the new child to both the parent and grandparent parent.children = [child] grandparent.grandchildren = [child] Is there a hook for me to add to the second collection automatically (i.e. an event when object is added to a collection)?
