Creating the Models for the Graphical Report
This example will use four models: event (app/models/event.rb), game (app/models/game.rb),
play (app/models/play.rb), and player (app/models/player.rb). Their code is shown in
Listings 5-13 through 5-16.
Listing 5-13. Event Model (app/models/event.rb)
class Event < ActiveRecord::Base
belongs_to :play
end
Listing 5-14. Game Model (app/models/game.rb)
class Game < ActiveRecord::Base
has_many :plays
end
Listing 5-15.
