即使加载了UJS, Rails DELETE调用也不能工作

为了这个我已经绞尽脑汁了。我在rails 4应用程序中使用设计来管理用户。我有两个部分的应用程序。管理端和用户端。

在管理端销毁会话工作得很好，但是用户端调用GET而不是DELETE。

下面是一些代码:

布局/discover.html.erb

<%= stylesheet_link_tag "user/discover_application", media: "all"%>
<%= javascript_include_tag 'user/discover_application' %>
<%= csrf_meta_tag %>

布局/发现/_modal.html.erb

<% if current_user %>
   <li><%= link_to(raw('<i class="fa fa-sign-out"></i> Logout'), destroy_user_session_path, :method => "delete")%></li>
 <% else %>
    <li><%= link_to raw('<i class="fa fa-sign-in"></i> Login'), new_user_session_path%></li>
 <% end %>

资产/javascript/user/discover_application.js

//= require user/modernizr
//= require jquery
//= require jquery_ujs

路线

devise_for :users, :controllers => {:registrations => "registrations", :sessions => "sessions"}
 resources :users
 root :to => "discover#index"

我在管理方面有一个几乎完全相同的东西，它工作正常，所以我完全迷路了。没有javascript错误，rails呈现的标记将数据方法显示为delete。任何帮助都是非常感激的。

Rails生成的实际链接

<a data-method="delete" href="/users/sign_out" rel="nofollow"><i class="fa fa-sign-out"></i> Logout</a>
