Ruby on Rails-无法删除（销毁）

Question

I am unable to delete a record in ruby on rails for some reason. 由于某种原因，我无法删除ruby中的记录。 I have tried many solutions unfortunately to no avail. 不幸的是，我尝试了许多解决方案都无济于事。 (such as How to delete / destroy a record in rails? ) （例如，如何在Rails中删除/销毁记录？）

The contents of my application.erb are: 我的application.erb的内容是：

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

<%= yield %>

</body>
</html>

when i open in html it only displays the following css it does not display js as in the tags above. 当我打开html时，它仅显示以下CSS，而不显示js，如上面的标记中所示。

<link data-turbolinks-track="true" href="/assets/scaffolds.css?body=1" media="all" rel="stylesheet" />
<link data-turbolinks-track="true" href="/assets/statuses.css?body=1" media="all" rel="stylesheet" />
<link data-turbolinks-track="true" href="/assets/application.css?body=1" media="all" rel="stylesheet" />

for my index.html.erb 对于我的index.html.erb

 <h1>Listing statuses</h1>

    <table>
      <thead>
        <tr>
          <th>Name</th>
          <th>Content</th>
          <th colspan="3"></th>
        </tr>
      </thead>

      <tbody>
        <% @statuses.each do |status| %>
          <tr>
            <td><%= status.name %></td>
            <td><%= status.content %></td>
            <td><%= status.id %></td>
            <td><%= link_to 'Show', status %></td>
            <td><%= link_to 'Edit', edit_status_path(status) %></td>
            <td><%= link_to 'Destroy', status , method: :delete, data: { confirm: 'Are you sure?' } %></td>
          </tr>
        <% end %>
      </tbody>
    </table>

    <br>

    <%= link_to 'New Status', new_status_path %>

i am troubleshooting this currently to no avail, if someone can pick any faults in this code, i would greatly appreciate. 我目前无法对此进行故障排除，如果有人可以在此代码中发现任何错误，我将不胜感激。 :) the js files are not showing in the head section of the page and the destroy function is not working, let alone the confirm tag. :) js文件未显示在页面的顶部，并且destroy函数无法正常工作，更不用说确认标签了。

Update : Now I am getting this error: 更新：现在我收到此错误：

TypeError: Object doesn't support this property or method Rails.root: [location] TypeError：对象不支持此属性或方法Rails.root：[位置]

if i remove the ' <%= javascript_include_tag %> ' it functions, although not fully (ie. does not delete like in the first instance) 如果我删除了“ <%= javascript_include_tag %> ”，它会起作用，尽管不能完全消除（即不会像第一个实例那样删除）

update 2 when i click on destroy button, it simply redirects me to view that particular status only, it does not destroy 更新2当我单击销毁按钮时，它只是将我重定向到仅查看该特定状态，而不会销毁

update 3 inside the application.js i have the following: 在application.js内部更新3我有以下内容：

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .

update 4 I have changed the <%= javascript_include_tag %> to <%= javascript_include_tag 'default', 'data-turbolinks-track' => true %> and it loads the js file however when i click on that js file from the sourcecode i get a routing error. 更新4我已经将<%= javascript_include_tag %>更改为<%= javascript_include_tag %> <%= javascript_include_tag 'default', 'data-turbolinks-track' => true %>并且它加载了js文件，但是当我从源代码中单击该js文件时我收到路由错误。 Any possible way i can solve that? 有什么办法可以解决这个问题？

Answer 1

Inside application.erb , you need to include your application.js file with javascript_include_tag like this: 在application.erb内部，您需要使用javascript_include_tag包含application.js文件，如下所示：

<%= javascript_include_tag 'application' %>

Assuming you have jquery and jquery_ujs set inside your application.js 假设你已经jquery和jquery_ujs设置你的内部application.js
