Link_to:method => :delete不使用jQuery在Rails 3中进行路由以销毁

问题描述：

我正在尝试使它成为笔记的销毁动作的链接:

I'm trying to make this be a link to a destroy action for a note :

 <%= link_to "delete", @note, :method => :delete, :confirm => "Are you sure" %>

这只是路由到音符，而不会执行销毁操作...鉴于此:

This just routes to the note and doesn't go through to the destroy action... Whereas this:

 <%= button_to "delete", @note, :method => :delete, :confirm => "Are you sure" %>

路由正确.我正在使用jQuery 1.7，并安装了gem'jquery-rails'，'> = 1.0.12'(其中包括jquery_ujs.js文件).

Does route properly. I'm using jQuery 1.7 and I installed the gem 'jquery-rails', '>= 1.0.12' (which includes the jquery_ujs.js file).

有哪些修复程序可以使link_正常工作?出于某种原因，我有一个较旧的应用程序，这些link_to链接可在其上运行，但我不记得为什么.任何指针?

What fixes are there to make link_to work properly? For some reason, I have an older app on which these link_to links work, but I can't remember why.. Any pointers?

(我真的不想使用button_to.这种样式很烦人，我敢肯定必须有一种方法可以做到这一点.)

(I really don't want to use button_to.. this styling is annoying, and I'm sure that there must be a way to do this..)

更新:使用Rails 3.0.9

UPDATE: Using Rails 3.0.9

答

您不是从jquery-rails加载jquery_ujs.js文件.确保在布局中同时需要jquery和jquery_ujs.

You're not loading the jquery_ujs.js file from jquery-rails. Ensure that you're requiring both jquery and jquery_ujs in your layout.

这两个文件通常包含在app/assets/javascripts/application.js文件中，该文件包含以下内容:

These two files are typically included in the app/assets/javascripts/application.js file, which contains this content:

//= require jquery
//= require jquery_ujs
//= require_tree .

如果您不在此行的布局中包含此内容:

If you're not including this in your layout with this line:

<%= javascript_include_tag "application" %>

然后jquery.js和jquery_ujs.js文件都不会被包含，因此:method => :delete请求将无法正常工作.

Then both the jquery.js and jquery_ujs.js files won't be included, and so the :method => :delete requests will not work as intended.
