The Rails API Gem
It is often asked: Is Rails a good fit if I only need to serve an API? In this episode I show how to use the Rails API gem to create a slimmer Rails application designed to respond with JSON.
(9 minutes)
Rails Modularity
Rails is a modular framework allowing you to include only what you need. Here I show how the smallest Rails app works, and then I take a look at how to whittle down a full Rails application stack.
(13 minutes)
Rails Metal (revised)
Rails metal may have been removed in Rails 3, but it is possible to bypass the entire Rails stack through middleware as shown in this episode.
(6 minutes)
Rails Middleware Walkthrough
Here I describe each Rack middleware that is included in a Rails app which will give you a better understanding of what a request goes through behind the scenes before it hits your application.
(14 minutes)
Handling Exceptions (revised)
By default, Rails will render a static error file when an exception occurs in production. Here you will learn how to fully customize this behavior and render dynamic error pages.
(11 minutes)
Rack in Rails 3
The router in Rails 3 is fully compatible with Rack. Learn how to embed Sinatra into an app, handle redirects, and improve on Rails Metal.
(8 minutes)
Action Controller Walkthrough
Do you ever wonder what goes on behind the scenes when a Rails controller handles a request? What do the "render" and "redirect_to" methods do exactly? This and more covered as we walk through the code of ActionController::Base.
(11 minutes)
Batch API Requests
Here I demonstrate how to perform bulk API operations though a single request using Rack middleware. This is great if you need to trigger multiple actions at once such as if the user goes offline.
(18 minutes)
Routing in Rails 3
Rails 3 sports a new routing interface. In this episode I show how to translate the old interface into the new one and show off a few new features.
(13 minutes)
Authentication with Warden
Warden makes it easy to move authentication up into Rack middleware. This means authentication can be accessed outside of a Rails controller such as in routes or in a mountable engine.
