Here’s a bunch of RoR tutorials from the web. The canonical book on the topic is Agile Web Development with Rails.
- HelloWorld example created in RadRails. Note that the resulting application didn’t seem to work for me, but it at least shows the basics of using RadRails.
- IBM developerWorks RadRails tutorial. Assumes some RoR knowledge, focuses on RadRails IDE.
- ONLamp Rolling with Ruby on Rails Revisited Part 1 and Part 2
- Using Ruby of Rails for Web Development on Mac OS X. Obviously this one is Mac-focused.
