Rails：：method =>：刪除尋找'show'動作

我已經安裝了Enki（博客）gem https://github.com/xaviershay/enki以及使用Devise進行註冊的Forem（論壇）gem https://github.com/radar/forem。一切似乎除了當我點擊一個鏈接Rails：：method =>：刪除尋找'show'動作

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

刪除帖子（或其他東西）論壇內進行工作，我收到此錯誤信息

Unknown action 

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

我注意到，培訓就業部鏈接有:method => :delete所以這不應該發生。另外，當我沒有使用Enki的時候使用Forem，我不會遇到這個問題。我認爲由於某種原因，rails應用程序沒有看到：method =>：delete，所以該方法被註冊爲「show」而不是destroy操作，但我不知道爲什麼。在日誌文件中，它說

* REQUEST_METHOD : GET –

我猜有某種路由衝突的多數民衆贊成禁用：方法=>：刪除，但我無法弄清楚。

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

您是否檢查日誌文件中的HTTP方法？ – nambrot 2012-02-14 07:32:20

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

確保被包含在佈局文件你的JavaScript：

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

對於刪除，你應該使用button_to來代替。 Link_to不應該用於HTTP POST請求。

這應該是'<％= javascript_include_tag：application％>'如果他使用的是Rails 3.1。然後應用程序應該包含適當的jQuery文件。 – 2012-02-14 19:32:24

看起來你必須在控制器中沒有方法show。只需定義它。

但爲什麼刪除方法需要顯示操作？刪除使用破壞不顯示。如果我定義了一個show動作，它不會根據需要刪除。 – Leahcim 2012-02-14 07:24:16

這是相同的路線不同，只有通過http方法 – ck3g 2012-02-14 07:27:04

都應該罰款=）您可以嘗試 – ck3g 2012-02-14 07:27:49

您需要在您的Gemfile jQuery的Rails的寶石

gem 'jquery-rails'

然後，你必須捆綁運行安裝並重新啓動服務器。這是因爲即使你已經在你的layout.html.erb中包含了jQuery框架，你也需要jQuery的適配器來使用unobstrusive腳本。

這是因爲rails jquery_ujs文件沒有得到加載在您的JavaScript。

在佈局文件執行此操作，normaly命名爲application.html.erb

<%= javascript_include_tag "application" %>

這將包括的application.js文件，還包括你的jquery_ujs文件

您應該檢查應用程序/ assets/application.js文件這條線存在那裏

//= require jquery_ujs

如果不是自己添加它。

它可以治好:)

提示：當您不使用的application.js

1 - 這可能會導致：

其中一個可能是問題的原因

2-您正在使用不同的文件包含庫，並忘記inlucde jquery_ujs那裏
