ruby-on-rails – Rails link

我很抱歉问什么可能是一个补救问题,但在学习rails时我试图按照本教程中的注释说明：

http://guides.rubyonrails.org/getting_started.html

我昨晚在本教程中发布了一个类似的问题并得到了一个迅速响应,这对我帮助很大,所以我希望同样如此.先感谢您.

第5.14节：删除帖子

我被指示向index.html.erb页面添加删除链接

<h1>Listing Posts</h1>
<table>
  <tr>
    <th>Title</th>
    <th>Text</th>
    <th></th>
    <th></th>
    <th></th>
  </tr>

<% @posts.each do |post| %>
  <tr>
    <td><%= post.title %></td>
    <td><%= post.text %></td>
    <td><%= link_to 'Show',post_path %></td>
    <td><%= link_to 'Edit',edit_post_path(post) %></td>
    <td><%= link_to 'Destroy',post_path(post),method: :delete,data: { confirm: 'Are you sure?' } %></td>
  </tr>
<% end %>
</table>

产生：

<td><a data-confirm="Are you sure?" data-method="delete" href="/posts/1" rel="nofollow">Destroy</a></td>

对我来说看起来不错,但是当我点击链接时,我既没有得到确认,也没有指向删除操作.它会生成此HTTP操作

Request URL:http://localhost:3000/posts/1 
Request Method:GET 
Status Code:200 OK

Rails：4,Ruby：2,64位windows 8,chrome：版本28.0.1500.72 m

再次感谢你

添加application.html.erb

<!DOCTYPE html>
<html>
<head>
  <title>Listing</title>
  <%= stylesheet_link_tag    "application",media: "all","data-turbolinks-track" => true %>
  <%= javascript_include_tag :application %>
  <%= csrf_Meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

产生了这个错误：
