Building a Forum From Scratch with Ruby on Rails

Learn how to refactor by taking logic out of the view and moving it to the controller, cleaning up the view in the process.

An in-depth look at RESTful programming in Rails.

While it certainly makes no attempt to constitute a complete guide to the Ruby language, this tutorial will introduce you to some of the basics of Ruby. We'll power through a crash-course in object oriented programming, covering the more common features of the language along the way, and leaving the more obscure aspects of Ruby for a dedicated reference guide. I'll also point out some of the advantages that Ruby has over other languages when it comes to developing applications for the Web.

Getting Started with Restful Authentication in Rails

Nested resources were introduced in Rails 1.2 and are touted as the Right Way to do REST with parent-child model associations. If your app has a url that reads something like /employees?company_id=1, a switch to nested resources would cause it to read /companies/1/employees. Here's a detailed guide to developing with these new changes in mind.

No need to pass foreign keys in find conditions, just do the find through a has_many association.

This week we're going to talk about ruby syntax. After this tutorial, I believe that you'll have a much better understanding of the framework and feel much more comfortable doing things by yourself.

Move a find into the model to clean up the controllers and remove duplication. Also see how you can call these custom find methods through an association.

It may have a goofy syntax, but the Symbol#to_proc feature Rails adds allows you to do simple blocks very quickly and easily.
