Introduction video to ActiveResources RESTful Rails controller actions

The world is talking about REST. Just when you are reading voraciously about Ruby and Rails, what would be nicer than having DHH to tell you what the next version of Rails' vision is regarding the whole REST idea?

Consider how you would write 4 named routes for the following ActiveController actions today:

POST /people/create
GET /people/show/1
POST /people/update/1
POST /people/destroy/1

ActionController::Routing::Routes.draw do |map|
map.with_options(:controller => 'people') do |people|
people.connect 'people/create', :action => 'create'
people.connect 'people/show/:id', :action => 'show'
people.connect 'people/update/:id', :action => 'update'
people.connect 'people/destroy/:id', :action => 'destroy'

How many times have you done CRUD on a model? With ActiveResources, all your need is 1 line of route setting:

  POST /people
GET /people/1
PUT /people/1
DELETE /people/1

ActionController::Routing::Routes.draw do |map|
map.resources :person

Convention over configuration can buy you a lot of coding. Rails does just that here (and more). Enjoy.

Only bonus funds contribute path of|in path of} any wagering requirements. You’ll play free 포커 online slot games with curious bonus rounds and fun video graphics. And then there are the random games that don’t seem to fall into any theme besides, maybe, whacky.
