User has_one :betslip Betslip belongs_to :user Betslip has_many :predictions Prediction belongs_to :betslip Prediction has_one :race Prediction has_one :racer Race has_many :racers Race has_one :winner, :through => :racers Racers .... Are separate? Unless each racer can only participate in one race, in which case Racer belongs_to :race I think that's basically what you're looking for. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
