In the first examples of building migrations rails generate … was used. I am running Ruby 1.9.2 and Rails 2.3 and under these condition this only succeeds in creating a new rails application by the name of generate. When I use the older ruby script/generate … the commands work. Will this be a major difference for rails 3? You probably should have some comment about this in the book.

This edition is specific to Rails 3.0. If you intend to follow along with this book, I strongly recommend that you don’t skip chapter 1.

Yes, the commands used will be a major difference. One of many, I’m afraid.

As an indication of the scope of the differences, I’ve been maintaining a list of the changes required to get the instructions in edition 3 to work with Rails 3.0. But in many ways, that’s just the beginning. Yesterday, I posted an overview of the changes between Rails 2.3 and Rails 3.0.
