【问题描述】：

我在我的 rails 应用程序中使用 devise 进行身份验证。我可以登录和注销，也可以注册。但是，一旦用户登录，我想为用户提供一种修改登录密码的方法。为此，该应用程序提供了一个指向 'edit_user_registration_path' 的链接，该链接显示在下面的 rake 路由输出中。

当用户点击下方修改密码链接时，

<li><%= link_to "Change Password", edit_user_registration_path %></li>

我收到以下错误

ActionController::RoutingError (No route matches {:action=>"edit", :controller=>"users"}):

我有一个带有显示、编辑和更新操作的 UsersController。编辑操作是更新用户模型的其他列。

路线设置如下

devise_for :users
resources  :users, only: [:show, :edit, :update]

rake 路由输出 -

    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
                     PUT    /users/password(.:format)      devise/passwords#update
cancel_user_registration GET    /users/cancel(.:format)        devise/registrations#cancel
   user_registration POST   /users(.:format)               devise/registrations#create
new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
edit_user_registration GET    /users/edit(.:format)          devise/registrations#edit
                     PUT    /users(.:format)               devise/registrations#update
                     DELETE /users(.:format)               devise/registrations#destroy
           edit_user GET    /users/:id/edit(.:format)      users#edit
                user GET    /users/:id(.:format)           users#show
                     PUT    /users/:id(.:format)           users#update
                root        /                              home#index

控制台日志如下

【问题讨论】：

你能给我们看看：app/views/layouts/_header.html.erb:22
我相信你是在自己调用edit_user_path，而没有告诉它要编辑哪个用户。
如你所料，我使用的是edit_user_path。这有什么问题吗？如何在此处指示用户？
