class Ladder < ActiveRecord::Base
has_many :players
has_many :users, :through => :players
end
class Player < ActiveRecord::Base
belongs_to :users
belongs_to :ladders
end
class User < ActiveRecord::Base
has_many :players
has_many :ladders, :through => :players
end
When I try the following code (on the console) I get an error:
@ladder = Ladder.find(1)
@ladder.users
I get this error:
NameError: uninitialized constant Ladder::Users
