合并ActiveRecord::Relation与ActiveRecord::Associations

Question

我有两个模型

class User < ActiveRecord::Base
    has_many :games

    def created_games
        Game.where(created_by: self.id)
    end
end

class Game < ActiveRecord::Base
    belongs_to :user
end

u = User.take
joined_games = u.games
created_games = u.created_games

变量joined_games是ActiveRecord::Associations的实例，而created_games是ActiveRecord::Relation的实例。

有没有办法让我把joined_games和created_games结合在一起？

Answer 1

尝试在用户模型中添加作用域

scope :joined_games, where(user_id: self.id, created_by: self.id)
