Interesting. I might be persuaded to recommend something else. What alternatives do you think are better?
1. Micheal Heartl's Rails Tutorial. 2. Pragmatic Programmers Bookshelf - Agile Rails 3.2 (4th Edition)
Both are a good start but delve far too much into unit testing with the horrific RSpec. When you're learning something new, you don't want to muddle with learning a DSL on top of things.
