It does not seem to be working.When I click this url, it just takes me to the show path.Can someone please tell me how to fix this. Thanks.
它似乎不起作用。当我单击此 url 时，它只会将我带到显示路径。有人可以告诉我如何解决这个问题。谢谢。

Are you using jQuery? If so, I think the problem could be that you are using jQuery without the updated rails.js file.
你在使用 jQuery 吗？如果是这样，我认为问题可能是您在使用 jQuery 时没有更新 rails.js 文件。
Download rails.js here: https://github.com/rails/jquery-ujs/raw/master/src/rails.jsDrop it in your javascripts directory, overwriting the rails.js that comes default with rails.
在此处下载 rails.js：https: //github.com/rails/jquery-ujs/raw/master/src/rails.js 将其放入您的 javascripts 目录中，覆盖 Rails 默认附带的 rails.js。
Add a javascript include line to include it.
添加一个 javascript 包含行以包含它。
<%= javascript_include_tag "rails" %>
Put this after your Jquery include tag. You probably also want to disinclude the javascript defaults if you don't plan on using prototype.
把它放在你的 Jquery 包含标签之后。如果您不打算使用原型，您可能还想取消 javascript 默认值。
I included jQuery UI in my application, I found that delete is now working as show, but after doing above Resolved Issue.
我在我的应用程序中包含了 jQuery UI，我发现删除现在可以正常工作，但是在完成上述已解决的问题之后。

Make sure these lines appear in application.js:
确保这些行出现在application.js：
//= require jquery
//= require jquery_ujs

Ensure that you have java script turned on. Otherwise :method => :deleteacts just as show in Rails.
确保您已打开 Java 脚本。否则:method => :delete就像在 Rails 中显示的一样。

If you're using restful routing for blogs, then the following should work:
如果您正在为博客使用静态路由，那么以下应该有效：
<%= link_to "Delete", @blog, :method => :delete, :confirm => "Are you sure ?"%>

You can try with 'data-method' instead of :method.
您可以尝试使用 'data-method' 而不是 :method。
<%=link_to "Delete",blog_path(@blog.id), 'data-method' => :delete, :class => "delete", :confirm => "Are you sure ?"%>
You can check on jquery_ujs.js the following piece of code:
您可以在 jquery_ujs.js 上查看以下代码：
// Handles "data-method" on links such as:
// <a href="/users/5" data-method="delete" rel="nofollow" data-confirm="Are you sure?">Delete</a>

In order for link_toto work with the deletemethod, Rails needs the unobtrusive scripting adapter for jQuery.
为了link_to使用该delete方法，Rails 需要不显眼的 jQuery 脚本适配器。
Make sure that your Gemfilehas
gem 'jquery-rails'Make sure that app/assets/javascripts/application.jshas
//= require jquery//= require jquery_ujsMake sure that your app/views/layouts/application.html.erbhas
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %><%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>inside the
headtag. Remove the'data-turbolinks-track' => truesection if you don't plan to use Turbolinks.
确保你的Gemfile有
gem 'jquery-rails'确保 app/assets/javascripts/ application.js有
//= require jquery//= require jquery_ujs确保你的 app/views/layouts/ application.html.erb有
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %><%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>内部
head标签。'data-turbolinks-track' => true如果您不打算使用 Turbolinks，请删除该部分。
