"There are two ways to build a many-to-many relationship. The first way uses a has_many association with the :through option and a join model, so there are two stages of associations. For the second way, use has_and_belongs_to_many in both models. This requires a join table that has no corresponding model or primary key." -- You received this message because you are subscribed to the Google Groups "Hobo Users" group.
