ruby-on-rails – routes.rb的未知错误

嘿,我是Rails的新手,当我去localhost时,我一直收到这个错误：3000 /

路由错误

没有路线匹配[GET]“/”
尝试运行rake路线以获取有关可用路线的更多信息.

这就是我的routes.rb文件的样子.

SampleApp::Application.routes.draw do
  get "static_pages/about"
  get "static_pages/contact"
  get "static_pages/help"
  get "static_pages/home"

end

我的views文件夹看起来像这样

views/static_pages/about.html.erb
views/static_pages/contact.html.erb
views/static_pages/help.html.erb
views/static_pages/home.html.erb

我运行了rake routes命令并得到以下信息：

Davids-MacBook-Air:sample_app DavidStevenson$rake routes
   static_pages_home GET /static_pages/home(.:format)    static_pages#home
   static_pages_help GET /static_pages/help(.:format)    static_pages#help
  static_pages_about GET /static_pages/about(.:format)   static_pages#about
static_pages_contact GET /static_pages/contact(.:format) static_pages#contact

任何想法都出错了？

您只是忘了定义根路由.把它放在你的路线文件的末尾：

root to: 'static_pages#home'

现在,当您访问localhost：3000 /时,您将看到static_pages_home页面.

检查this guide以获取有关路线的所有信息.

编辑

以下是您的路径文件的外观：

SampleApp::Application.routes.draw do
  get "static_pages/about"
  get "static_pages/contact"
  get "static_pages/help"
  get "static_pages/home"

  root to: 'static_pages#home'
end
