Let''s imagine we are modelling a company that have several shops. I have a Worker model and a Shop model. A worker belongs_to a shop, and each shop has_many workers. But, in a shop there''s a distinguished worker that is the supervisor create table shops ( ... worker_id integer -- the supervisor ); How would you express this relationship?
