在我的应用程序上使用 Devise 退出时出现问题

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。一切似乎都很好，除了我似乎无法退出。

我得到错误：

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

我可以将错误追溯到我的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要尝试为我的用户呈现显示操作。总体而言，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，我的退出路径如下所示：

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

如果用户没有登录，它应该呈现基本上是静态 html 的启动页面。关于如何提供帮助的任何建议？即使您可以将我放在正确的球场上，也将不胜感激。

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 rake 路线：

Answer 1

其实，忽略我之前的回答，试试这个：

<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，并且它需要在您的用户的路由之上，因为路由是自上而下工作的。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？

我想您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
