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

<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>

我运行了rake路由,确认所有路由都是有效的。

同样,在我的路线上。我有belonge_for:users和root:to => "home#index"。

当点击“签出”链接时,我得到以下路由错误:

No route matches "/users/sign_out"

知道是什么导致了这个错误吗?


当前回答

另一个选项是将注销配置为GET而不是DELETE,您可以在/config/initializers/ devie.rb上添加以下行

config.sign_out_via = :get

但正如Steve Klabnik在他的博客(http://blog.steveklabnik.com/2011/12/11/devise-actioncontroller-routingerror-no-route-matches-get-slash-users-slash-sign-out.html)上所写的,尝试使用DELETE,因为这种方法的语义。

我在rails 3.1.0中遇到了同样的问题,我解决了在文件中添加以下行:

app/assets/javascripts/application.js
//= require_tree
//= require jquery
//= require jquery_ujs

我认为退出的路由是一个DELETE方法。这意味着你的签出链接需要看起来像这样:

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

你的不包括:method =>:delete部分。另外,请注意,要实现这个功能,你还必须在布局文件(application.html.erb)中包含<%= javascript_include_tag:defaults %>。

这就是我所做的(Rails 3.0和design 1.4.2):

确保你的页面加载rails.js 使用这个参数:'data-method' => 'delete' 添加这个参数是个好主意::rel => 'nofollow'

在你的路线上。rb:

 devise_for :users do
    get '/sign_out' => 'devise/sessions#destroy'
    get '/log_in' => 'devise/sessions#new'
    get '/log_out' => 'devise/sessions#destroy'
    get '/sign_up' => 'devise/registrations#new'
    get '/edit_profile' => 'devise/registrations#edit'
 end

在你的application.html.erb中:

<%if user_signed_in?%>
          <li><%= link_to "Sign_out", sign_out_path %></li>
<% end %>

这个问题已经有很多答案了。对我来说,问题有两个方面:

when I expand my routes: devise_for :users do get '/users/sign_out' => 'devise/sessions#destroy' end I was getting warning that this is depreciated so I have replaced it with: devise_scope :users do get '/users/sign_out' => 'devise/sessions#destroy' end I thought I will remove my jQuery. Bad choice. Devise is using jQuery to "fake" DELETE request and send it as GET. Therefore you need to: //= require jquery //= require jquery_ujs and of course same link as many mentioned before: <%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
