ruby-on-rails - Rails 3 - belongs_to user AND has_many users

Question

我正在尝试弄清楚如何执行以下操作:

一场音乐会属于一个用户(创作者)，有_很多客人和有_很多组织者。

下面的方法好吗？

音乐会:

 class Concert < ActiveRecord::Base
  belongs_to :user
  has_many :guests, :class_name => 'User'
  has_many :organisers, :class_name => 'User'
 end

用户:

 class User < ActiveRecord::Base
  has_many :concerts
 end

提前致谢

Answer 1

添加两个新模型来保存 has_many 关系:

 class Concert < ActiveRecord::Base
  belongs_to :user
  has_many   :concert_guests
  has_many   :concert_organizers

  has_many   :guests, :through => :concert_guests, :source => :user
  has_many   :organizers, :through => :concert_organizers, :source => :user
 end

 class User < ActiveRecord::Base
  has_many :concerts
 end

 # table with user_id and concert_id columns   
 class ConcertGuest
   belongs_to :user
   belongs_to :concert
 end

 # table with user_id and concert_id columns   
 class ConcertOrganizer
   belongs_to :user
   belongs_to :concert
 end
