Robert Evans has written a very good tutorial for people who’d like to get their feet wet with Rails. The tutorial walks you through creating a very simple application, while touching on some basic Rails concepts. If you’re new to Ruby on Rails, I would recommend this tutorial. If you like what you see in the tutorial, I suggest reading Agile Web Development with Rails: A Pragmatic Guide, Whyâ??s (Poignant) Guide to Ruby, and Rails Recipes.
