使用Devise in Rails 3.2.3 - 无法登出 [英] Using Devise in Rails 3.2.3 - Cannot sign out

问题描述

我正在使用devise 2.1.0作为我的rails应用程序3.2.3。这是我做的：

 将gem'devise'添加到Gemfile并运行bundle 
运行rails g devise：install 
运行rails g devise用户
通过运行rake db来设置db：migrate 
  

application.html.erb是这样的：

 <％if user_signed_in？ ％GT; 
欢迎<％= current_user.email％> 
<％= link_to退出，destroy_user_session_path％> 
<％else％> 
<％= link_to注册，new_user_registration_path％>或
<％= link_to登录，new_user_session_path％> 
<％end％> 
  

登录并注册工作很好，但当我点击退出时，我收到一条错误消息：

路由错误

没有路由匹配[GET]/ users / sign_out尝试运行rake路线

这里是耙路线的输出： / p>

  new_user_session GET /users/sign_in(.:format）devise / sessions＃new 
 user_session POST / users / sign_in devise / sessions＃创建
 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 / passwo rd / edit（。：format）devise / passwords＃edit 
 PUT /users/password(.:format）devise / passwords＃update 
 cancel_user_registration GET /users/cancel(.:format）设计/注册#cancel 
 user_registration POST /users(.:format）设计/注册＃创建
 new_user_registration GET /users/sign_up(.:format）设计/注册＃new 
 edit_user_registration GET / users / edit （。：format）设计/注册＃编辑
 PUT /users(.:format）设计/注册＃update 
 DELETE /users(.:format）设计/注册＃destroy 
  

我真的很困惑，因为那里有/ usrs / sign_out路由。有没有人知道为什么？

解决方案

尝试这样：

 <％= link_to退出，destroy_user_session_path，：method => ：删除％> 
  




I am using devise 2.1.0 for my rails app 3.2.3. Here is what I did:

Add gem 'devise' to Gemfile and run bundle
Run rails g devise:install
Run rails g devise User
Setup db by running rake db:migrate

The application.html.erb is something like this:

<%if user_signed_in? %>
    Welcome <%= current_user.email%>
    <%= link_to "Sign out", destroy_user_session_path%>
<% else %>
    <%= link_to "Sign up", new_user_registration_path %> or
    <%= link_to "Sign in", new_user_session_path %> 
<% end %>

The sign in and sign up work just fine but When I click Sign out, I got an error message:

Routing Error

No route matches [GET] "/users/sign_out" Try running rake routes for more information on available routes.

Here is the output of the rake routes:

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

I am really confused as there are /usrs/sign_out routes in there. Does anyone know why?

解决方案

Try this:

<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
