我正在更新我的应用程序，因此我使用Devise gem进行身份验证。一切似乎都很有效，除了我似乎无法退出的事实。
我收到错误：
Couldn't find User with ID=sign_out
Parameters:
{"id"=>"sign_out"}
我可以将错误追溯回用户控制器中的show动作：
def show
@user = User.find(params[:id])
end
问题在于我不确定为什么它会尝试为我的用户呈现show动作。总的来说，我的页面有这种格式：
<% 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：
<li><%= link_to "Sign out", destroy_user_session_path %></li>
如果用户未登录，则应该呈现基本上是静态html的启动页面。有关如何帮助的任何建议？即使你可以把我放在正确的球场上就问题而言也会非常感激。
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'

实际上，请忽略我之前的回答并试试这个：
<li><%= link_to "Sign out", destroy_user_session_path, :method => :delete %></li>

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线之上，因为路由从上到下工作。如果您发布路线文件，我可以提供更多帮助。
您的resources :users可能会devise_for :users吗？
我猜你也可以尝试确定设计路线：
devise_scope :users do
get "sign_out", :to => "devise/sessions#destroy"
end
