First thing to understand is that there is no many-to-many association here. As you said a Message belongs_to a user and Message has many recipients, which are Users. So you basically just need to add a foreign key to User to keep track of the one-to-many relation Message <--->> User. We just need to do a bit of convention overriding to accomplish this: User has_many :messages Message belongs_to :user has_many :recipients, :class_name => "User", :foreign_key => :recipient_message_id Or if you want to make things more clear you could do: Message belongs_to :sender, :class_name => "User", :foreign_key => :sender_id has_many :recipients, :class_name => "User", :foreign_key => :recipient_message_id -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
