問題在我的應用程序中籤出設計

Question

我正在更新我的應用程序，因此我使用Devise gem進行身份驗證。除了我似乎無法退出這一事實之外，一切似乎都工作得很好。

我得到的錯誤：

Couldn't find User with ID=sign_out 
Parameters: 
{"id"=>"sign_out"} 

我可以跟蹤誤差回show動作在我的用戶控制：

def show 
    @user = User.find(params[:id]) 
    end 

的問題是，我不知道爲什麼它正試圖爲我的用戶呈現顯示操作。總的來說我的網頁的格式如下：

<% if user_signed_in? %> 
    <%= render 'shared/feed_home' %> 
<% else %> 
    <%= render 'shared/splash' %> 
<% end %> 

按色器件的說明，我的簽出路徑是這樣的：

<li><%= link_to "Sign out", destroy_user_session_path %></li> 

如果用戶沒有登錄，就應該使飛濺頁，其中基本上是靜態的HTML。有關如何提供幫助的建議？即使你可以把我放在正確的球場中，這個問題將非常值得讚賞。

Here is my routes file: 


    devise_for :users 
    resources :users do 
    member do 
     get :following, :followers, :following_tags, :following_posts 
    end 
    end 
    resources :posts 

    resources :votes 
    resources :comments 
    resources :tags 
    resources :events 

    #resources :posts, :only => [:create, :destroy, :show] 
    resources :relationships, :only => [:create, :destroy] 

    root :to =>'pages#subscribed' 


    match '/contact', :to => 'pages#contact' 
    match '/about', :to => 'pages#about' 
    match '/live', :to => "pages#home" 
    match '/voted', :to => 'pages#highest_voted' 
    match '/signup', :to => 'users#new' 

這裏是我的耙路線：

Answer 1

其實，忽略我以前的答案，試試這個：

<li><%= link_to "Sign out", destroy_user_session_path, :method => :delete %></li> 

Answer 2

問題可能是在你的routes.rb文件。您需要適當地路由user/signout，並且它需要位於用戶的路由之上，因爲路由是自上而下的。如果你張貼你的路線文件，我可以幫助更多。

您是否在devise_for :users之上有resources :users？

我想你也可以嘗試將範圍的色器件路線：

devise_scope :users do 
     get "sign_out", :to => "devise/sessions#destroy" 
    end
