Question

我有三款游戏＆gt;团队＆gt;玩家和我希望能够提交以下内容，以便与这些团队中的多个团队和玩家一起添加游戏。

{"game"=>{"name"=>"championship", "teams_attributes"=>[
    {"result"=>"won", "players_attributes"=>{"name"=>"Bob"}}, 
    {"result"=>"lost", "players_attributes"=>{"name"=>"Tad"}}]}}

以下是我的模特：

class Game < ActiveRecord::Base
   attr_accessible  :name, :teams_attributes, :players_attributes

   # Associations
   has_many :teams, :inverse_of => :game
   has_many :players, :through => :teams

   accepts_nested_attributes_for :teams
   accepts_nested_attributes_for :players
end

class Team < ActiveRecord::Base
     attr_accessible :game_id, :result, :players_attributes

     # Associations
     belongs_to :game, :inverse_of => :teams
     has_many :players, :inverse_of => :team

     accepts_nested_attributes_for :players
end

class Player < ActiveRecord::Base
  attr_accessible :team_id, :name

  # Associations
  belongs_to :team, :inverse_of => :players
  # belongs_to :game, :through => :team (causes error, doesn't fix)

end

我可以在添加游戏时添加两个团队，但我无法添加游戏，在每个团队中添加两个团队和玩家。我的设置有问题吗？尝试添加时，我不断收到“无法将字符串转换为整数”错误。这是我刚刚玩游戏时遇到的错误＆gt;团队，但是当我添加了inverse_of的东西时修复了。

谢谢！

想出来......我的哈希设置存在问题。正在使用：

{"game"=>{"name"=>"championship", "teams_attributes"=>[
{"result"=>"won", "players_attributes"=>{"name"=>"Bob"}}, 
{"result"=>"lost", "players_attributes"=>{"name"=>"Tad"}}]}}

但应该是（在players_attributes周围括号）：

{"game"=>{"name"=>"championship", "teams_attributes"=>[
{"result"=>"won", "players_attributes"=>[{"name"=>"Bob"}]}, 
{"result"=>"lost", "players_attributes"=>[{"name"=>"Tad"}]}]}}

无法让accepted_nested_attributes_for深入两个级别？
