Another type of many-to-many association is a rich join between two models. This is useful when the join table needs to include additional information about the relationship. In this case, the table does have an “id” as a primary key and there is a model corresponding to the database join table. Instead of using “has_and_belongs_to_many”, a rich join uses two sets of “has_many/belongs_to”.
