ruby-on-rails - ActiveRecord::AssociationTypeMismatch:用户预期，得到 Fixnum

Question

我不明白为什么会出现以下错误:

ActiveRecord::AssociationTypeMismatch: User(#29943560) expected, got Fixnum

当我在 Rails 控制台中执行此操作时:@game = Game.create(:player => 1060, :played => 1061)

我只想创建一个关于下面模型关联的新游戏。

class User < ActiveRecord::Base
    has_many :game_as_player, :class_name => 'Game', :foreign_key => 'player_id'
    has_many :game_as_played, :class_name => 'Game', :foreign_key => 'played_id'
end

class Game < ActiveRecord::Base
    belongs_to :player, :class_name => 'User'
    belongs_to :played, :class_name => 'User'

    attr_accessible :player, :played, :score, :details, :viewed, :read
end

如果有人有想法...非常感谢!

Answer 1

它只是说它需要一个 User 并且你给出一个 Fixnum

你应该做类似的事情

@game = Game.create(:player => Player.find(1060), :played => Player.find(1061))

或者，如果您想通过 ids 为用户提供

@game = Game.create(:player_id => 1060, :played_id => 1061)
