在我的应用程序上使用 Devise 注销时出现问题

Question

我正在更新我的应用程序，因此我使用 Devise gem 进行身份验证。一切似乎都运行良好，除了我似乎无法注销这一事实。

我收到错误：

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

我可以将错误追溯到用户控制器中的显示操作：

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

问题是我不确定它为什么尝试为我的用户呈现显示操作。总的来说，我的页面具有以下格式：

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

根据设计说明，我的注销路径如下所示：

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

如果用户未登录，它应该呈现基本上是静态 html 的启动页面。关于如何提供帮助有什么建议吗？即使你能让我在问题上处于正确的位置，我也会非常感激。

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'

这是我的耙子路线：

Answer 1

实际上，忽略我之前的回答并尝试这个：

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

Answer 2

问题可能出在您的 routes.rb 文件中。您需要适当地路由user/signout，并且它需要位于用户的路由之上，因为路由是从上到下工作的。如果您发布路线文件，我可以提供更多帮助。

您的 devise_for :users 上方是否有 resources:users ？

我想你也可以尝试确定设计路线的范围：

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