As far as setting up the many-to-many relationship using has_and_belongs_to_many, this is pretty well covered in the Rails guide on Active Record associations ( http://guides.rubyonrails.org/association_basics.html#the-has_and_belongs_to_many-association) and the API documentation ( http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html#method-i-has_and_belongs_to_many). I think this answers your question, but repost if not.
