But, if I call that method again, it will delete the `profile` record.

It looks weird for me. Is it a normal behaviour, or am I doing something wrong??

Well the delete makes sense to me - you're creating a new user preference, so the old one should be destroyed since this is a has_one and you've configured the relationship as dependent: :destroy. Not sure why it doesn't create a new one though
