ActionDispatch::Routing

The routing module provides URL rewriting in native Ruby. It's a way to redirect incoming requests to controllers and actions. This replaces mod_rewrite rules. Best of all, Rails' Routing works with any web server. Routes are defined in config/routes.rb.

Think of creating routes as drawing a map for your requests. The map tells them where to go based on some predefined pattern:

Rails.application.routes.draw do
  Pattern 1 tells some request to go to one place
  Pattern 2 tell them to go to another

end

The following symbols are special:

:controller maps to your controller name
:action     maps to an action with your controllers

Other names simply map to a parameter as in the case of :id.
