Question

我在阅读Michael Hartl的教程时遇到了这个错误。第5.3.2节（Rails路线）。

routes.rb 文件的内容为

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..我已经按照每条指令行事了尝试访问“

”中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

这是我在这些网页上遇到的错误

操作控制器：已捕获异常

Routing Error

    contact_path  GET      /contact(.:format)    static_pages#contact

Answer 1

看看你没有任何路线"/static_pages/about"

所以你有错误

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

根据您的关于页面/about的路线应该是网址

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

它会实际调用您的static_pages控制器和该控制器的about操作

从你获得的铁路线路的url helper

关于：

应该使用

about_path或about_url

联系

contact_path或contact_url

寻求帮助

help_path或help_url

Answer 2

你必须使用这些：

http://localhost:3000/         <!-- Maps to /home -->
http://localhost:3000/help       <!-- Maps to /static_pages/help-->       
http://localhost:3000/about       <!-- Maps to /static_pages/about-->       
http://localhost:3000/contact       <!-- Maps to /static_pages/contact-->

Answer 3

static_pages#about的路径

/约

而不是

/ static_pages /约

路由错误::没有路由匹配[GET]“/ static_pages / about”
