在安装的引擎中设计使用错误的 url 作为 401

Question

我在 Rails 应用程序 (my_application) 的已安装引擎 (my_engine) 中使用 Devise。这工作得很好，但仍然存在一个问题：如果用户试图访问受限资源（即受 before_filter authenticate_user! 保护的页面）Devise/Warden 生成 401 响应并重定向到 sign_in url。不幸的是，这个 sign_in url 没有以引擎的安装路径为前缀。

所以我的问题是 Devise 用于将浏览器转发到 sign_in 页面的 url 是错误的。

引擎的 routes.rb 文件是...

My_Engine::Engine.routes.draw do

  devise_for :users, {
                       class_name: "My_Engine::User",
                       module: :devise,
                       controllers: {registrations: 'my_engine/users/registrations'}
                     }
  devise_scope :user do
    get 'users/registrations/after_sign_up/:id' => "users/registrations#after_sign_up", as: :after_sign_up
    get 'users/registrations/after_confirm/:id' => "users/registrations#after_confirm", as: :after_confirm
  end
end

生成的路由都ok:

Prefix Verb URI Pattern Controller#Action
  my_engine      /my_engine       My_Engine::Engine

Routes for My_Engine::Engine:
        new_user_session GET    /users/sign_in(.:format)                         devise/sessions#new
            user_session POST   /users/sign_in(.:format)                         devise/sessions#create
    destroy_user_session DELETE /users/sign_out(.:format)                        devise/sessions#destroy
           user_password POST   /users/password(.:format)                        devise/passwords#create
       new_user_password GET    /users/password/new(.:format)                    devise/passwords#new
      edit_user_password GET    /users/password/edit(.:format)                   devise/passwords#edit
                         PATCH  /users/password(.:format)                        devise/passwords#update
                         PUT    /users/password(.:format)                        devise/passwords#update
cancel_user_registration GET    /users/cancel(.:format)                          my_engine/users/registrations#cancel
       user_registration POST   /users(.:format)                                 my_engine/users/registrations#create
   new_user_registration GET    /users/sign_up(.:format)                         my_engine/users/registrations#new
  edit_user_registration GET    /users/edit(.:format)                            my_engine/users/registrations#edit
                         PATCH  /users(.:format)                                 my_engine/users/registrations#update
                         PUT    /users(.:format)                                 my_engine/users/registrations#update
                         DELETE /users(.:format)                                 my_engine/users/registrations#destroy
       user_confirmation POST   /users/confirmation(.:format)                    devise/confirmations#create
   new_user_confirmation GET    /users/confirmation/new(.:format)                devise/confirmations#new
                         GET    /users/confirmation(.:format)                    devise/confirmations#show
           after_sign_up GET    /users/registrations/after_sign_up/:id(.:format) my_engine/users/registrations#after_sign_up
           after_confirm GET    /users/registrations/after_confirm/:id(.:format) my_engine/users/registrations#after_confirm

现在，当我访问受保护的资源时，Devise 会生成 401 并重定向到 sign_in 路径，但 url 没有前缀为“/my_engine”。

它使用/users/sign_in，但应该使用/my_engine/users/sign_in。

19:41:11 web.1  | Started GET "/my_engine/users/edit" for ::1 at 2015-03-09 19:41:11 +0100
19:41:11 web.1  | Processing by My_Engine::Users::RegistrationsController#edit as HTML
19:41:11 web.1  | Completed 401 Unauthorized in 1ms
19:41:11 web.1  | 
19:41:11 web.1  | 
19:41:11 web.1  | Started GET "/users/sign_in" for ::1 at 2015-03-09 19:41:11 +0100
19:41:11 web.1  | 
19:41:11 web.1  | ActionController::RoutingError (No route matches [GET] "/users/sign_in"):
19:41:11 web.1  |   actionpack (4.2.0) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'

有没有人遇到过这个？似乎引擎中的 omniauthenticable 存在相关问题，但我不确定它们是否具有相同的原因。

Answer 1

看看Ativ的回答，解决了我的问题。

简而言之，我不得不在引擎的lib文件夹中添加一个Devise::FailureApp，告诉Devise使用它并在启动时加载它。
