Product Description
Product Description
You want to write professional-grade applications: Rails is a full-stack, open-source web framework, with integrated support for unit, functional, and integration testing. It enforces good design principles, consistency of code across your team (and across your organization), and proper release management.
But Rails is more than a set of best practices. Rails makes it both fun and easy to turn out very cool web applications. Need Ajax support, so your web applications are highly interactive? Rails has it built in. Want an application that sends and receives e-mail? Built in. Supports internationalization and localization? Built in. Do you need applications with a REST-based interface (so they can interact with other RESTful applications with almost no effort on your part)? All built-in.
With this book, you'll learn how to use ActiveRecord to connect business objects and database tables. No more painful object-relational mapping. Just create your business objects and let Rails do the rest. Need to create and modify your schema? Migrations make it painless (and they're versioned, so you can roll changes backward and forward). You'll learn how to use the Action Pack framework to route incoming requests and render pages using easy-to-write templates and components. See how to exploit the Rails service frameworks to send emails, implement web services, and create dynamic, user-centric web-pages using built-in Javascript and Ajax support. There is extensive coverage of testing, and the rewritten Deployment chapter now covers Phusion Passenger.
As with the previous editions of the book, we start with an extended tutorial that builds parts of an online store. And, of course, the application has been rewritten to show the best of Rails V2.

I'm writing this review because I disagree strongly with some of the previously submitted reviews that rated this book poorly.
This IS the book I'd HIGHLY recommend to anyone with a programming background who has gone through intro-level RoR books and online tutorials and wants to delve deeper into understanding the framework, in terms of gotchas, tips, recommended coding practices, etc.
When I go to a book store and pick up a book, I skim through it, look at the content, and see if the author(s) covered important or complex topics with an appropriate level of detail. This book nailed that part. Even in skimming the book for 5 minutes, I found explanations for several issues I had run into while learning RoR. E.g. with a has-one / belong-to relationship between 2 models, when does the relationship get saved if you associate the parent in the child, or associate the child to the parent? Things like that, which are relevant to programmers build real applications, are invaluable to know.
One thing that makes the book excellent is how well it explains options and their tradeoffs for implementation of functionality. E.g. there is an excellent writeup on the options for managing session data.
I would suggest starting with Rails Foundations 2 and moving to this book later. The Foundations author does a superb job of explaining the rails framework, ActiveRecord, views, and controllers in the 1st 7 chapters before jumping into building an application. Overall that book and Simply Rails 2 strike a better balance between application development and instruction.
It's gotta be hard to put out a book against such a fast-moving target, and to their credit I think they did a pretty good job - for example, they were able to sneak in a description about named scopes.
My main gripe is that REST has been adopted by the Rails community for quite some time, and I think the tutorial should have been rewritten to reflect this, i.e. it could have done wihout the "add_to_cart", "who_bought", etc. actions in the controllers.
Listmania!
