RoutingError未初始化的常量 [英] RoutingError uninitialized constant

问题描述

我想在我的应用程序中使用token_authenticatable（使用Devise）。

使用这个答案我在文件 app / controllers / users_sessions_controller.rb中添加了 class Users :: SessionsController / code>（文件位置是否正确？）。要在数据库中生成authentication_token，我添加了一行 current_user.reset_authentication_token！作为create方法的第四行。

使用设计修改我添加了行 devise_for：users，：controllers => {：sessions => users / sessions} 到我的路线。

我还有文件 app / views / users / session / new.html.erb 。

现在，当我尝试登录或退出浏览器时，我得到路由错误未初始化的常量用户。

我不知道会发生什么。我认为我命名控制器类错了，或者把它放在错误的位置，但不知道。

解决方案

控制器名为 Users :: SessionsController 然后它需要在 app / controllers / users / sessions_controller.rb

如果您不想为控制器嵌套文件夹，您还可以执行

  class UserSessionsController 
  

位于 app / controllers / user_sessions_controller.rb 路由为： devise_for：users，：controllers => {：sessions => user_sessions}

I want to use token_authenticatable in my application (using Devise).

Using this answer I added class Users::SessionsController in file app/controllers/users_sessions_controller.rb (is file location correct?).

To generate authentication_token in database I added line current_user.reset_authentication_token! as fourth line of create method.

Using "Configuring Controllers" section from devise docimentation I added line devise_for :users, :controllers => {:sessions => "users/sessions"} to my routes.

I also have file app/views/users/session/new.html.erb.

Now when I try to log in or log out in browser, I get Routing Error uninitialized constant Users.

I have no idea what happens. I think I named controller class wrong, or placed it incorrectly, but don't know for sure.

解决方案

If you want your controller named Users::SessionsController then it need to be in app/controllers/users/sessions_controller.rb

If you don't want nested folders for your controllers you could also do

class UserSessionsController 

located at app/controllers/user_sessions_controller.rb with the routes being: devise_for :users, :controllers => {:sessions => "user_sessions"}
