ruby-on-rails - Rails 3 中的嵌套表单更新将外键设置为 NULL

Question

我正在尝试使用 formtastic 嵌套表单更新用户记录。其结构如下

User 
   Admin
   Address

当我发送表单以更新详细信息时，同时更新地址或管理员记录时，user_id(外键)被设置为 NULL。这是发送的数据，看起来没问题。

Parameters: {
             "utf8"=>"✓", "authenticity_token"=>"some token", 
             "user"=>{
                 "id"=>"16",
                 "first_name"=>"User", 
                 "last_name"=>"Name", 
                 "email"=>"username@gmail.com", 
                 "password"=>"[FILTERED]", 
                 "password_confirmation"=>"[FILTERED]", 
                 "address_attributes"=>{
                      "main_phone"=>"131231233", 
                      "address1"=>"Address 1 Line", 
                      "address2"=>"Address 2 Line", 
                      "city"=>"Lansing",  
                      "state"=>"Michigan", 
                      "zip"=>"48823", 
                      "user_id"=>"16"
                 }, 
                 "admin_attributes"=>{
                      "company_id"=>"2", 
                      "user_id"=>"16"
                 }, 
                 "roles_mask"=>"1", 
                 "user_id"=>"16"
                 }, 
                 "commit"=>"Update User Roles", 
                 "company_id"=>"2", 
                 "id"=>"16"
           }

用户模型

class User < ActiveRecord::Base
  has_one :address, :dependent => :destroy, :inverse_of => :user
  has_one :admin, :dependent => :destroy, :inverse_of => :user      
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  attr_accessible :email, :password, :password_confirmation, :remember_me, :first_name, :last_name, :roles_mask, :terms_of_use,:id
  attr_accessible :owner_attributes, :admin_attributes, :address_attributes, :client_attributes
  accepts_nested_attributes_for :owner, :admin, :client, :address  
end

管理模型

class Admin < ActiveRecord::Base
  belongs_to :company
  belongs_to :user, :inverse_of => :admin

  attr_accessible :company_id, :user_id
end

*地址模型

class Address < ActiveRecord::Base
  belongs_to :user, :inverse_of => :address


  attr_accessible :address1, :user_id, :address2, :city, :state, :zip, :main_phone, :cell_phone
end

你能帮我解决这个问题吗？谢谢。

已更新模型详细信息。我删除了验证以使其简短。

Answer 1

尽量改正

accepts_nested_attributes_for :owner, :admin, :client, :address

在你的用户模型中

accepts_nested_attributes_for :owner, :client
accepts_nested_attributes_for :admin, :address, :update_only => true
