私の Rails アプリでは、オブジェクト「Organization」と 2 つのサブオブジェクト「User」と「Settings」をネストされた形式で作成しています。フォームを実行すると、次のエラーが表示されます。

WARNING: Can't mass-assign protected attributes: user

私は以前に別のプロジェクトでこの問題を抱えていましたが、

@organization.users.build

organization_controller/new にあります。フォームの送信時にサブオブジェクトを追加してサブオブジェクトを作成するため。

organization.rb
class Organization < ActiveRecord::Base
  attr_accessible :org_name, :address1, :address2, :city, :state, :postal_code, :country, :logo_image, :setting_id, :active, :status_image, :users_attributes, :setting_attributes
  has_many :users, :dependent => :destroy
  has_one :setting, :dependent => :destroy
  accepts_nested_attributes_for :users
  accepts_nested_attributes_for :setting
end

user.rb
class User < ActiveRecord::Base
  attr_accessible :email, :password, :password_confirmation, :name_first, :name_last, :admin, :notes, :current_outstanding, :pin, :registered, :sms, :super_user, :organization_id

  belongs_to :organization
end

setting.rb
class Setting < ActiveRecord::Base
  attr_accessible :green_hours, :green_mins, :yellow_hours, :yellow_mins, :red_hours,   :red_mins, :reminder_sms, :reminder_sms_hours, :reminder_sms_mins, :logo_url, :comp_name, :alert_emails, :alert_smss, :history_hours, :time_zone, :user_id, :organization_id

  belongs_to :organization
end

organizations_controller.rb
class OrganizationsController < ApplicationController

  def new
    @organization = Organization.new
    @organization.build_setting
    @organization.users.build

    respond_to do |format|
      format.html { render :layout => 'application_dashboard_orgs' }
      format.json { render json: @organization }
    end
  end

  def create
    @organization = Organization.new(params[:organization])

    respond_to do |format|
      if @organization.save
        format.html { redirect_to organizations_path, notice: 'Organization was successfully created.' }
        format.json { render json: @organization, status: :created, location: @organization }
      else
        format.html { render action: "new" }
        format.json { render json: @organization.errors, status: :unprocessable_entity }
      end
    end
  end
end

<%= f.fields_for :user do |user| %>

あなたがしたいことは、フォームに裏打ちされたオブジェクトを使用することだと思います。Jeff Dean は、これに関する優れたブログ記事をhttp://pivotallabs.com/users/jdean/blog/articles/1706-form-b​​acking-objects-for-fun-and-profitで公開しています。

このエラーは、組織を保存しようとしたときに「ユーザー」属性を設定できないことを示しています。:userand:settingを attr_accessible 行に追加してみてくださいorganization.rb
