The Complete Guide to Avoiding and Fixing Common Rails 3 Code and Design Problems
As developers worldwide have adopted the powerful Ruby on Rails web framework, many have fallen victim to common mistakes that reduce code quality, performance, reliability, stability, scalability, and maintainability. Rails™ AntiPatterns identifies these widespread Rails code and design problems, explains why they’re bad and why they happen—and shows exactly what to do instead.
As developers worldwide have adopted the powerful Ruby on Rails web framework, many have fallen victim to common mistakes that reduce code quality, performance, reliability, stability, scalability, and maintainability. Rails™ AntiPatterns identifies these widespread Rails code and design problems, explains why they’re bad and why they happen—and shows exactly what to do instead.
The book is organized into concise, modular chapters—each outlines a single common AntiPattern and offers detailed, cookbook-style code solutions that were previously difficult or impossible to find. Leading Rails developers Chad Pytel and Tammer Saleh also offer specific guidance for refactoring existing bad code or design to reflect sound object-oriented principles and established Rails best practices. With their help, developers, architects, and testers can dramatically improve new and existing applications, avoid future problems, and establish superior Rails coding standards throughout their organizations.
This book will help you understand, avoid, and solve problems with
- Model layer code, from general object-oriented programming violations to complex SQL and excessive redundancy
- Domain modeling, including schema and database issues such as normalization and serialization
- View layer tools and conventions
- Controller-layer code, including RESTful code
- Service-related APIs, including timeouts, exceptions, backgrounding, and response codes
- Third-party code, including plug-ins and gems
- Testing, from test suites to test-driven development processes
- Scaling and deployment
- Database issues, including migrations and validations
- System design for “graceful degradation” in the real world

Finally, a Rails book worth reading!!!
17 Mar 2011
Format:Paperback|Amazon Verified Purchase
I'll be honest, prior to reading this book I was starting to lose faith in Ruby on Rails authors. As a beginner to Rails, I've read a number of books to try and make sense of all the black magic going on behind the scenes as well as how to write great code in Rails. Many of those books were either "paint by number" tutorials where you didn't really learn anything appreciable or very complete (and hard to comprehend) reference manuals for everything there is to possibly know about Rails.
I just needed a good in between book! This book not only exposes you to the Rails Way of writing code in Ruby on Rails, it also gives many of the opposing examples which I would more than likely stumble down not knowing any better.
Not only that, but this is one of the most logically organized books I have ever had the pleasure to read. Everything flows together very nicely and is very understandable for beginners let alone more advanced users.
I would recommend this book in a heart beat (and I already have... many, many times). Great job guys! I really appreciate the effort you put into writing this book! You have restored my faith in Rails authors!

Fantastic source of refactoring ideas
9 Dec 2010
Format:Paperback|Amazon Verified Purchase
This book makes a great companion to Martin Fowler's Refactoring book (or the Ruby version of it by Jay Fields). As someone who's still accumulating the theoretical 10,000 hours of experience it takes to master something (Ruby/Rails), it's nice to have guides like Chad and Tammer there to suggest improvements to my technique. Highly recommended for anyone novice or intermediate Rails developer.

A more useful way to teach design patterns
15 Jun 2011
Format:Paperback|Amazon Verified Purchase
All too often, the 'patterns' books only develop a greenfield example the 'right' way. This is hopelessly optimistic, especially if (as is the case for me) you're teaching undergraduates how to use design patterns; they're not going to get it right the first time. So *refactoring* code that has "grown bad" to use a good pattern is a much more frequently needed skill.
There are other books on refactoring for Ruby, like Martin's, but i like that this one focuses on design patterns and specifically on how to leverage Ruby's features to realize the patterns nicely.
My future coverage of design patterns in Berkeley's undergraduate software engineering class will be motivated by the examples in this book.
