Example:
class Article 'created_at DESC'

The default scope also carries across, by default, to [...]
Hot off the back of the Rails Guides hackfest came a lot of great new Rails documentation. Now joining that documentation comes an all new Ruby on Rails Security Guide.

Back in 2005, the first Rails application a novice Rails developer produced was typically a simple blog-like system.

Derek Haynes has written "4 Simple Steps to Detect & Fix Slow Rails Requests," an excellent guide to figuring out what's causing your Rails app to slow down, and what to do about it.

DZone has released a new entry in their "Refcardz" series (short PDFs that rapidly walk through a single topic) called Flexible Rails: Flex 3 on Rails 2. It was written by Peter Armstrong of Ruboss and covers how to use Adobe's Flex technology along with a Rails 2.x application. It's well designed and packs in [...]
Yo Rails! is a new site that makes it easy to find quality Rails links (to tutorials, screencasts, resource sites, etc) simply by narrowing down what you want by tags.
