Sinatra like routes in Rails controllers

A proof of concept of having Sinatra like routes inside your controllers.

How to use

Since the router is gone, feel free to remove config/routes.rb. Then add the file below to lib/action_controller/inline_routes.rb inside your app.

  #
  # Example: Make attribute immutable once saved
  # validates :attribute, change: false, on: :update
  #
  # Example: Force attribute change on every save
  # validates :attribute, change: true
  
  def initialize(options)

Recently, we've been working on extracting Ember conventions from applications we're working on into the framework. Our goal is to make it clearer how the parts of an Ember application work together, and how to organize and bootstrap your objects.

Routing

Routing is an important part of web applications. It allows your users to share the URL they see in their browser, and have the same things appear when their friends click on the link.

The Ember.js ecosystem has several great solutions for routing. But, since it is such an important part of most web applications, we've decided to build it right into the framework.

If you have already modeled your application state using Ember.StateManager, there are a few changes you'll need to make to enable routing. Once you've made those changes, you'll notice the browser's address bar spring to life as you start using your app—just by moving between states, Ember.js will update the URL automatically.

Routing in Ember

In Ember, the application's state manager handles routing. Let's take a look at a simple example:

App.stateManager = Ember.StateManager.create({
  start: Ember.State.extend({
    index: Ember.State.extend({
      route: "/",
