I'm pretty new to rails and trying to figure out relationships.
The data I'm trying to model is as follows: An Event is a gathering where people play games. An Event is recorded in multiple Videos. A Video contains multiple GameSets. A GameSet has two Players, player_one and player_two.
Because an Event has many Videos, and a Video has many GameSets, I feel like I should be able to declare a has_many :through relationship to get straight from an Event to GameSets. Also, I should be able to go straight from a player to all of the GameSets that he has participated in.
Here's what I have:
class Event < ActiveRecord::Base
attr_accessible :event_date, :event_name, :event_number, :city, :state, :game_sets, :videos
has_many :videos
has_many :game_sets, :through => :videos
end
class Video < ActiveRecord::Base
attr_accessible :name, :url, :event, :game_sets
belongs_to :event
has_many :game_sets
end
class GameSet < ActiveRecord::Base
attr_accessible :player_one, :player_two, :video
belongs_to :video
has_one :player_one, :class_name => "Player"
has_one :player_two, :class_name => "Player"
end
class Player < ActiveRecord::Base
attr_accessible :first_name, :handle, :home_city, :home_state, :last_name, :tag
has_and_belongs_to_many :game_sets
end
But when I try to execute code like:
GameSet.find_by_id(1).player_one
I get the following exception.
?[1m?[36mGameSet Load (0.0ms)?[0m ?[1mSELECT "game_sets".* FROM "game_sets" WHERE "game_sets"."id" = 1 LIMIT 1?[0m ?[1m?[35mPlayer Load (1.0ms)

I can't for the life of me figure out what it is I'm doing wrong. Any help is appreciated.
