我已将Enki（博客）gem https://github.com/xaviershay/enki与使用Devise进行注册的Forem（forums）gem https://github.com/radar/forem一起安装。除非我点击链接
，否则一切似乎都有效<li><%= link_to t('delete', :scope => 'forem.topic'), topic_post_path(@topic, post), :method => :delete, :confirm => t("are_you_sure") %></li>
删除论坛内的帖子（或其他任何内容），我收到此错误消息
Unknown action
The action 'show' could not be found for Forem::PostsController
我注意到Forem链接有:method => :delete所以这不应该发生。此外，当我使用没有Enki的Forem时，我没有遇到这个问题。我认为由于某种原因，rails应用程序没有看到：method =＆gt; ：删除所以该方法被注册为“show”而不是destroy动作，但我不知道为什么。在日志文件中它说
* REQUEST_METHOD : GET –
我猜测路由中存在某种冲突，导致禁用：method =＆gt; ：删除，但我无法弄明白。
配置/ routes.rb中
Enki::Application.routes.draw do
mount Forem::Engine, :at => "/forums"
devise_for :users
namespace 'admin' do
resource :session

post 'preview', :on => :collection

确保您的JavaScript包含在布局文件中：
<%= javascript_include_tag :defaults %> #Rails 3.0.x
<%= javascript_include_tag :application %> #Rails 3.1+
<%= csrf_meta_tag %>
对于删除，您应该使用button_to代替。 Link_to不应用于HTTP POST请求。

您需要在Gemfile中包含jQuery for Rails gem
gem 'jquery-rails'
然后你必须运行bundle install并重启服务器。这是因为即使你已经在layout.html.erb中包含了jQuery框架，你需要jQuery的适配器来使用不引人注目的脚本。

这是因为你的javascript中没有加载rails jquery_ujs文件。
在布局文件中执行此操作，通常命名为 application.html.erb
<%= javascript_include_tag "application" %>
这将包括application.js文件，还包括你的jquery_ujs文件
您应该检查app / assets / application.js文件，该行存在
//= require jquery_ujs
如果不自行添加。
它会治愈:)。
<强>提示：
其中一个可能是问题的原因：
1-当您不使用application.js时可能会导致
2-您正在使用不同的文件来包含库而忘记了 jquery_ujs
答案 3 :(得分：-2)
看起来你在该控制器中没有方法show。只需定义它。
