Rails中的遊戲匹配資源？

Question

構建模型關係和嵌套資源以構建遊戲的最佳方式是：用戶（來自設計），遊戲，玩家（連接遊戲/用戶表）。我的問題是用戶存在，但玩家需要與遊戲同時創建。創建一個遊戲也必須創建一個球員，這是可能的，但感覺噁心。有一個更好的方法嗎？我想避免使用事務或過濾器來創建新資源。謝謝。

class User < ActiveRecord::Base 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable 

    devise :omniauthable, :omniauth_providers => [:facebook, :twitter] 
    has_many :games 
end 

class Player < ActiveRecord::Base 
    validates :user_id, uniqueness: { scope: :game, 
     message: "can't join your own game" } 

    belongs_to :user 
    belongs_to :game 

    has_one :board 
    has_many :ships 
end 

class Game < ActiveRecord::Base 
    belongs_to :first_player, class_name: 'Player', foreign_key: 'first_player_id' 
    belongs_to :second_player, class_name: 'Player', foreign_key: 'second_player_id' 
    has_one :first_player_board, through: :first_player, source: :board 
    has_one :second_player_board, through: :second_player, source: :board 
end 

Answer 1

我結束了與玩家的模型做了所有在一起，並具有用戶have_many解決這個：遊戲。

class Game < ActiveRecord::Base 
    belongs_to :first_player, class_name: 'User', foreign_key: 'first_player_id' 
    belongs_to :second_player, class_name: 'User', foreign_key: 'second_player_id' 
    has_one :first_player_board, through: :first_player, source: :board 
    has_one :second_player_board, through: :second_player, source: :board 
end
