无法找到’破坏’动作，但它就在那里……奇怪的错误

我的应用程序似乎无法在我的Sessions控制器中找到“destroy”操作。 很奇怪，因为它就在那里。

我有这样的链接：

我在routes.rb路由到我的destroy动作：

 match '/logout' => "sessions#destroy", :as => "logout" 

这是我的会话控制器中的’destroy’动作：

 def destroy reset_session redirect_to videos_path end 

当我点击链接时，我在日志中收到此错误：

 Started GET "/logout" for 127.0.0.1 at Thu Mar 24 02:58:36 -0700 2011 AbstractController::ActionNotFound (The action 'destroy' could not be found for SessionsController): 

这里发生了什么？

更新：

这是我的routes.rb文件：

 root :to => "videos#new" resources :videos resources :video_votes resources :users resource :session match '/login' => "sessions#new", :as => "login" match '/logout' => "sessions#destroy", :as => "logout" 

SessionsController.instance_methods输出：

这是我的整个Sessions控制器：

 class SessionsController  'new' end def destroy reset_session redirect_to videos_path end end end 

Answer 1

看起来我搞砸了我的Sessions控制器中的end的位置导致我的destroy方法不起作用……

我不得不将我的Sessions控制器更改为：

 class SessionsController < ApplicationController def create if user = User.authenticate(params[:email], params[:password]) session[:user_id] = user.id redirect_to videos_path else flash.now[:alert] = "Invalid login/password combination" render :action => 'new' end end def destroy reset_session redirect_to videos_path end end 

Answer 2

尝试更改此行：

 match '/logout' => "sessions#destroy", :as => "logout" 

并使它看起来像这样：

 get '/logout' => "sessions#destroy", :as => "logout" 

它是相同的路线，但它只会响应获取此特定操作的请求。

Answer 3

好的，我想我明白了

将routes.rb更改为

 resources :sessions
