用户和他的联系人属于并且在rails中有许多关联

发布于 2024-11-12 06:11:05 字数 703 浏览 1 评论 0原文

我想管理用户及其与关系或联系人类型的联系人，有人可以建议我它的正确关联吗？

我想运行查询诸如 user.companions 之类的东西，它返回联系人列表列表。

如果有的话宝石可用，请指导我。谢谢

class CreateContacts < ActiveRecord::Migration
  def self.up
    create_table :contacts do |t|
      t.integer :companion_id
      t.references :user
      t.timestamps
    end
  end

  def self.down
    drop_table :contacts
  end
end

class User < ActiveRecord::Base
        has_many :contacts, :dependent => :destroy
        has_many :users, :through=>:contacts, :foreign_key => :companion_id
end
class Contact < ActiveRecord::Base
  belongs_to :user
  has_many :companions, :class_name=>'User', :foreign_key => :companion_id
end

您应该将您的联系人模型更改为：

class Contact < ActiveRecord::Base
  belongs_to :user
  belongs_to :companion, :class_name=>'User'
end

You should change your Contact model to:

class Contact < ActiveRecord::Base
  belongs_to :user
  belongs_to :companion, :class_name=>'User'
end

如果您想使用像“user.companions”这样的查询，那么应该将以下内容添加到您的用户模型中

class User < ActiveRecord::Base
        has_many :contacts, :dependent => :destroy
        has_many :companions, :foreign_key => "companion_id", :class_name => "Contact"
end

class Contact < ActiveRecord::Base
        belongs_to :user
end

If you want to use query like "user.companions", then should add the following to your User model

class User < ActiveRecord::Base
        has_many :contacts, :dependent => :destroy
        has_many :companions, :foreign_key => "companion_id", :class_name => "Contact"
end

class Contact < ActiveRecord::Base
        belongs_to :user
end
