設計管理模式無法完成會話控制器功能

Question

我正在構建一個基本的CRUD應用程序。用戶模型運行良好。但是，我創建了我的第二個設計模型（管理員），並且在使用我的管理員帳戶嘗試sign_in和sign_out時收到錯誤消息。

的誤差

uninitialized constant Admins::SessionsControllerController 

sessions_controllers.rb

管理控制器處於控制器/管理員/ sessions_controllers.rb

class Admins::SessionsController < Devise::SessionsController 
end 

的routes.rb

resources :gifts 
devise_for :users 
devise_for :admins, :controllers => { :sessions => "admins/sessions_controller" } 

authenticated :user do 
    root to: "gifts#index", :as => "authenticated_user_root" 
end 

authenticated :admin do 
    root to: "management#index", :as => "authenticated_admin_root" 
end 

root :to => 'pages#index' 

我也看到了正確的路線上來時，我耙路線：

destroy_user_session_path DELETE /users/sign_out(.:format) devise/sessions#destroy 

admin.rb

class Admin < ActiveRecord::Base 
    devise :database_authenticatable, :registerable, 
    :recoverable, :rememberable, :trackable, :validatable 
end

我正在尋求幫助以使我的管理模型正常工作。有誰知道如何讓這個工作正常？

你必須在devise_for一個錯字，

devise_for :admins, :controllers => { :sessions => "admins/sessions_controller" } 

應該

devise_for :admins, :controllers => { :sessions => "admins/sessions" }
