I have a model “Conversation” and a model “Leader”. A Conversation is always led by exactly 1 Leader. I’ve overridden Conversation’s “validate” method to validate the presence of an associated Leader model. If I add a similar validation to the Leader model, however, Conversations can no longer be saved on creation because the Leader model is invalid. On creation of both a new Conversation and
