Question

我是使用Rails的新手。我正在关注Treehouse“构建一个简单的Ruby on Rails应用程序”教程。直到现在，一切都很顺利。

我正在尝试生成设计视图但是当我转到localhost：3000 / users / sign_up时出现错误

Routing Error

No route matches [GET] "/"
Try running rake routes for more information on available routes.

当我转到用户/ sign_up，users / sign_in而不是去用户/编辑时会发生这种情况

当我尝试去用户/ sign_up时，终端向我吐口水

当我运行rake路线时，这就是它的样子

    Mikes-MacBook-Pro:treebook mike$ rake routes
    new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
        user_session POST   /users/sign_in(.:format)       devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format)      devise/sessions#destroy
       user_password POST   /users/password(.:format)      devise/passwords#create
   new_user_password GET    /users/password/new(.:format)  devise/passwords#new
  edit_user_password GET    /users/password/edit(.:format) devise/passwords#edit
                     PUT    /users/password(.:format)      devise/passwords#update
cancel_user_registration GET    /users/cancel(.:format)          devise/registrations#cancel
   user_registration POST   /users(.:format)               devise/registrations#create
new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new

                     PUT    /users(.:format)               devise/registrations#update
                     DELETE /users(.:format)               devise/registrations#destroy
            statuses GET    /statuses(.:format)            statuses#index
                     POST   /statuses(.:format)            statuses#create
          new_status GET    /statuses/new(.:format)        statuses#new
         edit_status GET    /statuses/:id/edit(.:format)   statuses#edit
              status GET    /statuses/:id(.:format)        statuses#show
                     PUT    /statuses/:id(.:format)        statuses#update
                     DELETE /statuses/:id(.:format)        statuses#destroy

我很难过接下来要做什么。任何帮助都非常感激！

Answer 1

您需要定义根路由，以便Rails知道在打开根路径时将某人发送到何处。

http://guides.rubyonrails.org/routing.html#using-root

一旦你登录，Devise就会想要重定向某个地方，没有根路线，它无处可去。

root to: "statuses#index"可能是一个开始的好地方

Answer 2

Rails无法找到您的root_url。

尝试将以下内容添加到routes.rb并重新启动服务器。

root to: '/'

其中root是路由器的辅助方法，从您的某个控制器获取选项hash to: 'controller#action'，例如users#index。

to的值可以包含字符串或其他红宝石对象，您将学习它们！

没有路由匹配[GET]“/”设计用户Sign_Up
