ruby-on-rails - 设计无法完成 session Controller 功能的管理模型

Question

我正在构建一个基本的 CRUD 应用程序。用户模型运行良好。但是，我创建了我的第二个设计模型(管理员)，并且在尝试使用我的管理员帐户登录和注销时收到错误消息。

错误

uninitialized constant Admins::SessionsControllerController

sessions_controllers.rb

管理 Controller 在controllers/admins/sessions_controllers.rb

class Admins::SessionsController < Devise::SessionsController
end

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'

当我搜索路线时，我也看到了正确的路线:

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

我正在寻求帮助以使我的管理模型正常工作。有谁知道如何让它正常工作？

你在 devise_for 中有错别字，

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

应该是

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