“无法质量分配受保护的属性”具有嵌套属性 [英] "Can't mass-assign protected attributes" with nested attributes

问题描述

我已经看到有其他问题的问题，但到目前为止，答案没有为我工作。我正在尝试注册一个用户的表单，同时创建一个组织。用户和组织通过分配表相关联。

I've seen other questions with this problem, but so far the answers haven't worked for me. I'm trying to have a form that registers a User, and creates an Organization at the same time. The User and Organization are associated via an assignment table.

这是我的表单：

= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f|

  = devise_error_messages!

  = f.fields_for :organizations do |f|

    = f.label :name
    = f.text_field :name

  = f.label :email
  = f.email_field :email

  = f.label :password
  = f.password_field :password

  = f.label :password_confirmation
  = f.password_field :password_confirmation

我的注册控制员：

class Users::RegistrationsController < Devise::RegistrationsController
  def new
    @user = User.new
    @user.organizations.build
  end

  def create
    super
  end

  def update
    super
  end
end

我的组织机构：

class Organization < ActiveRecord::Base
  has_many :organization_assignments
  has_many :users, :through => :organization_assignments

  attr_accessible :name
end

和我的用户型号：

class User < ActiveRecord::Base

  has_many :organization_assignments
  has_many :organizations, :through => :organization_assignments

  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  accepts_nested_attributes_for :organizations

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :organization_attributes
  # attr_accessible :title, :body

end

我得到的确切错误是：

无法大量分配受保护的属性：organizational_attributes

Can't mass-assign protected attributes: organizations_attributes

推荐答案

你必须添加：organizational_attributes 到 attr_accessible 在用户模型中。

You have to add :organizations_attributes to attr_accessible in the User model.
