Question

我陷入了奇怪的境地。我在SO论坛上看到了很多答案，但没有解决我的问题。我正在开发一个ruby on rails应用程序。我已创建注册并成功登录。但我的签出不起作用。这是我在应用程序标题

中注销的视图

<div class="header">
    <%= image_tag "header.png", :class => "headerimg" %>
    <% unless current_user.blank? %>
    <div id="menu_container" >
        <ul class="sf-menu" id="nav" >
            <li style="margin-left:10%">
               <%= link_to current_user.First_Name, {} %>    
            </li>
            <li>
               <%= link_to "notif", {} %>
            </li>
            <li id="logout" style="margin-left:55%;">
               <%= link_to "Log out", signout_path, method: "delete"  %>
            </li>
        </ul>
    </div>
    <% end %>
</div>

我的会话控制器是

def destroy 
    sign_out
    redirect_to root_url
end

我的会员帮助退出是

def sign_out        
    cookies.delete(:remember_token)
    self.current_user = nil
end

我的佣金路线的结果是：

Helper     HTTP Verb       Path     Controller#Action
Path / Url          
users_path      GET     /users(.:format)    users#index
                POST    /users(.:format)    users#create
new_user_path   GET     /users/new(.:format)    users#new
edit_user_path  GET     /users/:id/edit(.:format)   users#edit
user_path       GET     /users/:id(.:format)    users#show
                PATCH   /users/:id(.:format)    users#update
                PUT     /users/:id(.:format)    users#update
                DELETE  /users/:id(.:format)    users#destroy
sessions_path   POST    /sessions(.:format)     sessions#create
new_session_path    GET     /sessions/new(.:format)     sessions#new
session_path    DELETE  /sessions/:id(.:format)     sessions#destroy
root_path   GET     /   static_pages#home
signup_path     GET     /signup(.:format)   users#new
signin_path     GET     /signin(.:format)   sessions#new
signout_path    DELETE  /signout(.:format)  sessions#destroy
default_path    GET     /default(.:format)  static_pages#default

我无法弄清楚我在做什么。我跟随Michael Hartl。 Plz指出了我正确的方向。

由于

修改这是我得到的错误

No route matches [GET] "/signout"

您的link_to写得正确，但您可以看到它发出了GET请求。由于方法DELETE是使用javascript强制执行的，因此您很可能不会包含application.js，或者您的javascript中存在错误，导致无法正确解析它。

因此，请确保在您的应用程序布局（views/layouts/application.html.erb）

中

<%= javascript_include_tag "application" %>

或者检查浏览器javascript控制台中的错误。

注销路径没有匹配的路由
