没有路由匹配" /用户/ SIGN_OUT"制定轨道3 [英] No route matches "/users/sign_out" devise rails 3

问题描述

我已经在我的应用程序中安装了设备，并在我的 application.html.erb 文件中应用了以下内容：

 < div id =user_nav> 
<％user_signed_in？ ％GT; 
以<％= current_user.email％> ;.登录。这不能是奶酪？ 
<％= link_to'注销'，destroy_user_session_path％> 
<％else％> 
<％= link_to'Register'，new_user_registration_path％>或<％= link_to'登录'，new_user_session_path％> 
<％end％> 
< / div> 
  

我跑了 rake路线并确认所有路线是有效的。

此外，在我的 routes.rb 文件中我有 devise_for ：用户和 root：to => 回家＃指数。

点击退出链接时，出现以下路由错误：

 没有路线匹配/ users / sign_out
  

任何想法是什么导致错误？ / p>

解决方案

我认为退出的路由是一个 DELETE 方法。这意味着您的登出链接需要如下所示：

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

您的不包含：method => ：删除部分。另外，请注意，为了使其工作，您还必须在布局文件（ application.html）中包含<％= javascript_include_tag：defaults％> .erb ）。

I've installed devise on my app and applied the following in my application.html.erb file:

<div id="user_nav">
    <% if user_signed_in? %>
        Signed in as <%= current_user.email %>. This cannot be cheese?
        <%= link_to 'Sign out', destroy_user_session_path %>
    <% else %>
        <%= link_to 'Register', new_user_registration_path %> or <%= link_to 'Sign in', new_user_session_path %>
    <% end %>
</div>

I ran rake routes and confirmed that all the routes are valid.

Also, in my routes.rb file I have devise_for :users and root :to => "home#index".

I get the following routing error when clicking the "Sign out" link:

No route matches "/users/sign_out"

Any ideas what's causing the error?

解决方案

I think the route for signing out is a DELETE method. This means that your sign out link needs to look like this:

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

Yours doesn't include the :method => :delete part. Also, please note that for this to work you must also include <%= javascript_include_tag :defaults %> in your layout file (application.html.erb).
