路由错误没有路由匹配[GET]“/ static_pages / home”，教程

Question

When I run server browser show me something like this:

Routing Error

No route matches [GET] "/static_pages/home"

Try running rake routes for more information on available routes. 

Rake routes shows me this:

root  /                  static_pages#home
help  /help(.:format)    static_pages#help
about  /about(.:format)   static_pages#about
contact  /contact(.:format) static_pages#contact

My routes.rb file:

MyApp::Application.routes.draw do
root :to => 'static_pages#home'

match '/help',    :to => 'static_pages#help'
match '/about',   :to => 'static_pages#about'
match '/contact', :to =>'static_pages#contact'


end

Anyone got an idea?

Answer 1

There is no route set for the url '/static_pages/home'

Although root points to static_pages controller with action home, it still responds to the path '/' and not '/static_pages/home'

If you add

match '/static_pages/home', :to =>'static_pages#home'

You will get the expected response for '/static_pages/home'

Answer 2

step 5.3.3 Rails tutorial

You don't have to refresh your page

http://localhost:3000/static_pages/home

but only change the URL by

http://localhost:3000/

because you define 'static_pages/home' as root '/'.

For me it works

Answer 3

I just got the same error as szatan when I followed the Ruby on Rails tutorial. The error is because, previously, we test URL was http://localhost:3000/static_pages/help since the action is in static_pages. But, after changing routes.rb from

get 'static_pages/help' to
match '/help',    to: 'static_pages#help

The URL should changed to http://localhost:3000/help since we tell Rails server to route the path /help to static_pages#help . We shouldn't expect the user to know the path /static_pages/help .

Answer 4

Remember to remove the "public/index.html" file.

You can define all the routes properly, but if you leave this file, you won't be routing it properly.

Answer 5

I had this problem when I got to this point in the tutorial. It was resolved when I pointed the browser to "http://localhost:3000/" and reloaded.

Answer 6

You could point to "/" or root_path in stead of '/static_pages/home' . No need to point two routes to the same place...

Answer 7

you should add :as keword to define XXX_path,such as root :to => 'static_pages#home'

match '/', to: 'static_pages#home', :as => :home
match '/help',    to: 'static_pages#help', :as => :help
  match '/about',   to: 'static_pages#about', :as => :about
  match '/contact', to: 'static_pages#contact', :as => :contact
