ruby-on-rails - 路由错误::没有路由匹配 [GET] "/static_pages/about"

Question

我在阅读 Michael Hartl 的教程时遇到此错误。第 5.3.2 节(Rails 路线)。

我的routes.rb文件的内容是

SampleApp::Application.routes.draw do
   root  'static_pages#home'
  match '/help',    to: 'static_pages#help',    via: 'get'
  match '/about',   to: 'static_pages#about',   via: 'get'
  match '/contact', to: 'static_pages#contact', via: 'get'
end

我在 static_pages 的 rspec 是成功的..我已经按照每条说明进行操作但是尝试访问位于 `

的任何页面时仍然出现此错误

http://localhost:3000/static_pages/home
http://localhost:3000/static_pages/about
http://localhost:3000/static_pages/contact

这是我在这些页面上遇到的错误

Action Controller :捕获到异常

Routing Error

Answer 1

看你没有任何路线 "/static_pages/about"

所以你得到了错误

 Routing Error
 No route matches [GET] "/static_pages/about"

根据您关于页面的路由 /about 应该是 url

 http://localhost:300/about   
 http://localhost:300/contact 
 http://localhost:300/help

它会准确地调用您的static_pages Controller 和该 Controller 的about 操作

并从您获得的 rails 路线的 url 帮助程序

关于:

应使用

about_path 或about_url

联系方式

contact_path 或 contact_url

寻求帮助

help_path 或 help_url
