You can't use add() when specifying the intermediate model. You
would have to check all fields of the intermediate model and make
sure all of them have defaults or are allowed to be null. It might
not be worth the trouble of implementing it.
I don't see how this is different from the create method on the
intermediary model.
Cheers, Roald
