Rails Server Routing Error

问题:

I am getting a routing error when trying to access the web application with the URL for the localhost.

Ruby on Rails 3.2 and Windows 7 is used.

The Question:

Why does this routing error happen? And does anybody have a suggestion how to fix this?

The URL:

http://localhost:3000/web_app_name

The Error Message:

In the Web Browser:

Routing Error

No route matches [GET] "/web_app_name"

In the Command Prompt:

Started GET "/web_app_name" for 127.0.0.1

Addendum:

The "routes.rb" File:

web_app_name/config/routes.rb

WebAppName::Application.routes.draw do

end

The rake routes Command:

The rake routes command does not produce an output in the command prompt.

回答1:

Did you add the route in routes.rb file ?! Show it, please!

It should be something like:

root :to => "controller_name#action_name"
