Ruby on Rails Bible

I think it's interesting that people have given the book good reviews. 

Well, okay--the book may be, itself, a good review. But it's not possible to follow along with the example code. A block of code will be shown, which you can type into a file if you want. Then there'll be some analysis of that code...and it's not quite the same code when the author talks about it line-by-line. I was struggling along with the first application in the book, trying different versions to see what would work...oh, and I dunno about other databases, but with PostgresQL choosing "not null" for a field does not prevent saving an empty string (and why should it?)...anyway, I got tired of trying to make stuff actually work. 

I'm going to read the rest of the book, because I have it in front of me. But if there were a bookstore within 50 miles I'd just get something else. And the book is out of date. Rails 1.2, it says, and 2.3.3 is current.

Plus, from the acknowledgements: "I'd like to thank the people at Wiley whom [sic] identified me as a candidate to write this book..."

Lots of bad writing in here, which I expect from tech books, but that's just silly. Bad grammar, used to thank his editor....
