我通過Active Admin和Devise得到ActiveModel :: ForbiddenAttributesError

Question

我正在開發一個使用Active Admin和Devise的應用程序。 我已經修改了User和Admin Users表（通過遷移），以允許兩種模型都使用設備而不是Active Admin使用一個登錄過程。 作為“超級用戶”，管理員可以登錄並訪問“管理員活躍”。 應用程序用戶將無法訪問Admin Active。

當我嘗試創建新用戶或管理員時，會遇到我遇到的問題。 我收到以下錯誤：

ActiveModel::ForbiddenAttributesError in Admin::UsersController#create 

看起來很簡單，但我看不到。 這是代碼：

Schema.rb

ActiveRecord::Schema.define(version: 20140721134754) do

  create_table "active_admin_comments", force: true do |t|
    t.string   "namespace"
    t.text     "body"
    t.string   "resource_id",   null: false
    t.string   "resource_type", null: false
    t.integer  "author_id"
    t.string   "author_type"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "active_admin_comments", ["author_type", "author_id"], name: "index_active_admin_comments_on_author_type_and_author_id"
  add_index "active_admin_comments", ["namespace"], name: "index_active_admin_comments_on_namespace"
  add_index "active_admin_comments", ["resource_type", "resource_id"], name: "index_active_admin_comments_on_resource_type_and_resource_id"

  create_table "admin_users", force: true do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,  null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.string   "current_sign_in_ip"
    t.string   "last_sign_in_ip"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "admin_users", ["email"], name: "index_admin_users_on_email", unique: true
  add_index "admin_users", ["reset_password_token"], name: "index_admin_users_on_reset_password_token", unique: true

  create_table "users", force: true do |t|
    t.string   "email",                  default: "",    null: false
    t.string   "encrypted_password",     default: "",    null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,     null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.string   "current_sign_in_ip"
    t.string   "last_sign_in_ip"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.boolean  "superadmin",             default: false, null: false
  end

  add_index "users", ["email"], name: "index_users_on_email", unique: true
  add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true

end

應用程序/ admin.user.rb

問題發生在第三行，帶有create_or_edit >> @user.attributes = params[:user].delete_if do |k, v|

ActiveAdmin.register User do

  def registration_params
    params.require(:user).permit(:email, :password, :password_confirmation, :superadmin)
  end

  index do
    column :email
    column :current_sign_in_at
    column :last_sign_in_at
    column :sign_in_count
    actions
  end

  form do |f|
    f.inputs "User Details" do
      f.input :email
      f.input :password
      f.input :password_confirmation
      f.input :superadmin, :label => "Super Administrator"
    end
    f.actions
  end

  create_or_edit = Proc.new {
    @user            = User.where(id: params[:id]).first_or_create
    @user.superadmin = params[:user][:superadmin]
    @user.attributes = params[:user].delete_if do |k, v|
      (k == "superadmin") ||
      (["password", "password_confirmation"].include?(k) && v.empty? && !@user.new_record?)
    end
    if @user.save
      redirect_to :action => :show, :id => @user.id
    else
      render active_admin_template((@user.new_record? ? 'new' : 'edit') + '.html.erb')
    end
  }
  member_action :create, :method => :post, &create_or_edit
  member_action :update, :method => :put, &create_or_edit
end

如您所見，我已添加嘗試解決此問題的方法，但是它不起作用。

  def registration_params
    params.require(:user).permit(:email, :password, :password_confirmation, :superadmin)
  end

我也嘗試了以下針對ApplicationController解決方案，但仍然收到相同的錯誤消息。

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:email, :password, :password_confirmation, :superadmin, :remember_me)}
  end

我在這里想念什么!!？

更新中...

錯誤信息

ActiveModel::ForbiddenAttributesError in Admin::UsersController#create
ActiveModel::ForbiddenAttributesError

在第25行發生錯誤

應用程序/管理/ user.rb

22  create_or_edit = Proc.new {
23    @user            = User.where(:id => params[:id]).first || User.new
24    @user.superadmin = params[:user][:superadmin]
*25    @user.attributes = params[:user].delete_if do |k, v|*
26      (k == "superadmin") ||
27      (["password", "password_confirmation"].include?(k) && v.empty? && !@user.new_record?)
28    end
29    if @user.save
30      redirect_to :action => :show, :id => @user.id
