找不到id = sign_out的用户 [英] Couldn't find User with id=sign_out

问题描述

我已经检查了我的routes.rb，下面列出了我的application.html.erb看起来

获取以下错误。

  ActiveRecord :: RecordNotFound在UsersController＃show 
 
找不到用户id = sign_out 
 Rails.root：/ Users / patrickwalsh / rails_projects / ytutorial 
 
应用程序跟踪|框架跟踪|完整跟踪
 app / controllers / users_controller.rb：4：在`show'
 lib / disable_assets_logger.rb：11：在`call'
  

我的routes.rb

  Refectory :: Application.routes。 draw do 
 devise_for：users，：controllers => {：registrations => users} 
 devise_scope：user do 
 get'login'，to：devise / sessions＃new，as：login
 get'logout'，to：devise / session＃destroy，as：logout
 get'logout'，to：users / sessions＃destroy，as：logout
 get'signup'，to：users＃new ，as：signup
 match'/ users /：id'，：to => 'users＃show'，：as => ：user 
 end 
 root：to => 'tutorials＃index'
 
 devise_for：users do get'/ users / sign_out'=> 'devise / sessions＃destroy'
 get'users /：id'=> '用户＃显示'
结束
资源：教程
资源：仅注释：[：show，：create，：update，，destroy] 
 
 resources：教程做
成员{post：vote} 
 end 
 
如果Rails.env ==开发
匹配'errors / 404'=> 'errors＃error_404'
 match'errors / 500'=> 'error＃error_500'
 end 
 
除非Rails.application.config.consider_all_requests_local 
匹配'* not_found'，到：'errors＃error_404'
 end 
 
 match'tagged'=> 'tutorials＃tagged'，：as => 'tagged'
 end 
  

和我的application.html似乎遵循正确的路由从我可以看到。

任何帮助是非常感谢！

 <％if current_user.present？ ％GT; 
< li><％= link_to注销，destroy_user_session_path，（：method =>delete）％>< / li> 
<％else％> 
< li><％= link_to登录，new_user_session_path％>< / li> 
< li><％= link_to注册，new_user_registration_path％>< / li> 
<％end％> 
  

我的用户控制器以及我怀疑这是问题所在，但不知道什么错误是。

  class UsersController< Devise :: RegistrationsController 
 def show 
 @user = User.find（params [：id]）
 @tutorials = @ user.tutorials 
 end 
 end 
  

解决方案

您需要移动：

  devise_for：用户获取'/ users / sign_out'=> 'devise / sessions＃destroy'
  

在你的 devise_scope 。 Rails正在从路由文件顶部寻找路由。您的登出网址匹配 users /：id ，因此它试图以 sign_out 作为ID来呈现显示操作。

更新：

其实你真的需要你的 devise_scope中的最后一行块？

Sign-out link isn't working in my rails application.

I have checked my routes.rb which is listed below and my application.html.erb looks to follow the right path.

Getting the following error.

ActiveRecord::RecordNotFound in UsersController#show

Couldn't find User with id=sign_out
Rails.root: /Users/patrickwalsh/rails_projects/ytutorial

Application Trace | Framework Trace | Full Trace
app/controllers/users_controller.rb:4:in `show'
lib/disable_assets_logger.rb:11:in `call'

My routes.rb

Refectory::Application.routes.draw do
  devise_for :users, :controllers => { :registrations => "users" }
  devise_scope :user do
    get 'login', to: "devise/sessions#new", as: "login"
    get 'logout', to: "devise/sessions#destroy", as: "logout"
    get 'logout', to: "users/sessions#destroy", as: "logout"
    get 'signup', to: "users#new", as: "signup"
    match '/users/:id', :to => 'users#show', :as => :user
  end
  root :to => 'tutorials#index'

devise_for :users do get '/users/sign_out' => 'devise/sessions#destroy' 
get 'users/:id' => 'users#show'
end
  resources :tutorials
  resources :comments, only: [:show, :create, :update, :destroy]

 resources :tutorials do
    member { post :vote }
  end

  if Rails.env == "development"
    match 'errors/404' => 'errors#error_404'
    match 'errors/500' => 'errors#error_500' 
  end

  unless Rails.application.config.consider_all_requests_local
    match '*not_found', to: 'errors#error_404'
  end

  match 'tagged' => 'tutorials#tagged', :as => 'tagged'
end

and my application.html which seems to be following the right route from what I can see.

Any help is greatly appreciated!

<% if current_user.present? %>
          <li><%= link_to "Log out", destroy_user_session_path, (:method => "delete") %></li>
        <% else %>       
          <li><%= link_to "Log in", new_user_session_path %></li>
          <li><%= link_to "Sign up", new_user_registration_path %></li>
        <% end %>

My users controller as well as I have a suspicion this is where the problem lies but not sure what the error is.

class UsersController < Devise::RegistrationsController
def show
  @user = User.find(params[:id])
  @tutorials = @user.tutorials
end
end

解决方案

You need to move:

devise_for :users do get '/users/sign_out' => 'devise/sessions#destroy' 

over your devise_scope. Rails is looking for routes from top of Routes file. Your sign out url matches users/:id, hence it is trying to render show action with sign_out being an id.

UPDATE:

Actually, do you really need the last line in your devise_scope block?
