You may need to reload the object, as in if @whatever.save @whatever.reload @another_thing.whatever_id = @whatever.id @another_thing.save end That would only be true in a create method, because the ID isn't known until after the thing is saved. But if your relationships are declared in the usual way (has_many, belongs_to, etc.) then this plumbing is taken care of for you in most cases.
