我有这些课程:

class User
  has_one :user_profile
  accepts_nested_attributes_for :user_profile
  attr_accessible :email, :password, :password_confirmation, :user_profile_attributes
end

class UserProfile
  has_one :contact, :as => :contactable
  belongs_to :user
  accepts_nested_attributes_for :contact
  attr_accessible :first_name,:last_name, :contact_attributes
end

class Contact
   belongs_to :contactable, :polymorphic => true 
   attr_accessible :street, :city, :province, :postal_code, :country, :phone
end

我正在尝试将一条记录插入到所有 3 个表中,如下所示:

consumer = User.create!(
  [{
  :email => 'consu@a.com',
  :password => 'aaaaaa',
  :password_confirmation => 'aaaaaa',
  :user_profile => {
      :first_name => 'Gina',
      :last_name => 'Davis',
      :contact => {
        :street => '221 Baker St',
        :city => 'London',
        :province => 'HK',
        :postal_code => '76252',
        :country => 'UK',
        :phone => '2346752245'
    }
  }
}])

一条记录被插入到users表中,但没有插入到user_profilesorcontacts表中。也不会发生错误。

做这种事情的正确方法是什么?

已解决(感谢@Austin L. 提供链接

params =  { :user =>
    {
    :email => 'consu@a.com',
    :password => 'aaaaaa',
    :password_confirmation => 'aaaaaa',
    :user_profile_attributes => {
        :first_name => 'Gina',
        :last_name => 'Davis',
        :contact_attributes => {
            :street => '221 Baker St',
            :city => 'London',
            :province => 'HK',
            :postal_code => '76252',
            :country => 'UK',
            :phone => '2346752245'
          }
      }
  }
}
User.create!(params[:user])

您的用户模型需要设置为通过以下方式接受嵌套属性accepts_nested_attributes

有关更多信息和示例,请参阅 Rails 文档:http: //api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html

编辑:您也可能要考虑使用has_one :contact, :through => :user_profilewhich 将允许您访问这样的联系人:@contact = User.first.contact.

rails c编辑2:在我能找到的最佳解决方案中玩耍之后是这样的:

@c = Contact.new(#all of the information)
@up = UserProfile.new(#all of the information, :contact => @c)
User.create(#all of the info, :user_profile => @up)
