Rails：：method =>：删除寻找'show'动作

我已经安装了Enki（博客）gem https://github.com/xaviershay/enki以及使用Devise进行注册的Forem（论坛）gem https://github.com/radar/forem。一切似乎除了当我点击一个链接Rails：：method =>：删除寻找'show'动作

<li><%= link_to t('delete', :scope => 'forem.topic'), topic_post_path(@topic, post), :method => :delete, :confirm => t("are_you_sure") %></li>

删除帖子（或其他东西）论坛内进行工作，我收到此错误信息

Unknown action 

The action 'show' could not be found for Forem::PostsController

我注意到，培训就业部链接有:method => :delete所以这不应该发生。另外，当我没有使用Enki的时候使用Forem，我不会遇到这个问题。我认为由于某种原因，rails应用程序没有看到：method =>：delete，所以该方法被注册为“show”而不是destroy操作，但我不知道为什么。在日志文件中，它说

* REQUEST_METHOD : GET –

我猜有某种路由冲突的多数民众赞成禁用：方法=>：删除，但我无法弄清楚。

的config/routes.rb中

Enki::Application.routes.draw do 
    mount Forem::Engine, :at => "/forums" 
    devise_for :users 

    namespace 'admin' do 
    resource :session 

    resources :posts, :pages do 
     post 'preview', :on => :collection 
    end 
    resources :comments 
    resources :undo_items do 
     post 'undo', :on => :member 
    end 

    match 'health(/:action)' => 'health', :action => 'index', :as => :health 

    root :to => 'dashboard#show' 
    end 

    resources :archives, :only => [:index] 
    resources :pages, :only => [:show] 

    constraints :year => /\d{4}/, :month => /\d{2}/, :day => /\d{2}/ do 
    get ':year/:month/:day/:slug/comments' => 'comments#index' 
    post ':year/:month/:day/:slug/comments' => 'comments#create' 
    get ':year/:month/:day/:slug/comments/new' => 'comments#new' 
    get ':year/:month/:day/:slug' => 'posts#show' 
    end 

    scope :to => 'posts#index' do 
    get 'posts.:format', :as => :formatted_posts 
    get '(:tag)', :as => :posts 
    end 

    root :to => 'posts#index' 
end

您是否检查日志文件中的HTTP方法？ – nambrot 2012-02-14 07:32:20

@nambrot * REQUEST_METHOD：GET – Leahcim 2012-02-14 07:48:56

确保被包含在布局文件你的JavaScript：

<%= javascript_include_tag :defaults %> #Rails 3.0.x 
<%= javascript_include_tag :application %> #Rails 3.1+ 
<%= csrf_meta_tag %>

对于删除，你应该使用button_to来代替。 Link_to不应该用于HTTP POST请求。

这应该是'<％= javascript_include_tag：application％>'如果他使用的是Rails 3.1。然后应用程序应该包含适当的jQuery文件。 – 2012-02-14 19:32:24

-2

看起来你必须在控制器中没有方法show。只需定义它。

但为什么删除方法需要显示操作？删除使用破坏不显示。如果我定义了一个show动作，它不会根据需要删除。 – Leahcim 2012-02-14 07:24:16

这是相同的路线不同，只有通过http方法 – ck3g 2012-02-14 07:27:04

都应该罚款=）您可以尝试 – ck3g 2012-02-14 07:27:49

您需要在您的Gemfile jQuery的Rails的宝石

gem 'jquery-rails'

然后，你必须捆绑运行安装并重新启动服务器。这是因为即使你已经在你的layout.html.erb中包含了jQuery框架，你也需要jQuery的适配器来使用unobstrusive脚本。

这是因为rails jquery_ujs文件没有得到加载在您的JavaScript。

在布局文件执行此操作，normaly命名为application.html.erb

<%= javascript_include_tag "application" %>

这将包括的application.js文件，还包括你的jquery_ujs文件

您应该检查应用程序/ assets/application.js文件这条线存在那里

//= require jquery_ujs

如果不是自己添加它。

它可以治好:)

提示：当您不使用的application.js

1 - 这可能会导致：

其中一个可能是问题的原因

2-您正在使用不同的文件包含库，并忘记inlucde jquery_ujs那里
