Hi there, I’ve a quick question. I owned the first edition of this book, and I’m happy with that.. but then since I’m not very active in the rails community I thought it might be a good idea to read the 2nd edition to see what I’ve missed. I’ve got the book from the library now, but I can’t hold it for too long, so I’m wondering if anyone could give me some hints.. which part of the book is actually changed? where should I start? Thanks!
