How to avoid the most common code and design mistakes in Ruby on Rails applications - and refactor away problems that already exist • •A unique guide to improving Rails code quality, performance, reliability, stability, scalability, and maintainability. •Practical, proven techniques for ensuring that every new Rails application reflects today's best practices. •Highly realistic: reflects Rails mistakes and bad habits the authors have repeatedly seen 'in the wild' As millions of web developers have turned to the Ruby on Rails framework, many have fallen victim to the same mistakes, misconceptions, and bad habits. These errors can significantly reduce code quality, performance, reliability, stability, scalability, and maintainability. In some cases, they can even derail a project. In this book, these common Rails code and design problems are compiled into a complete set of AntiPatterns: what they look like, why they happen, why they're bad - and what to do instead. Every AntiPattern is illuminated with real world code, as well as specific guidance for refactoring existing bad code or design to reflect sound Object Oriented principles and established Ruby on Rails best practices. This 'cookbook' is organized into short, concise, easy-to-use chapters - each outlining a single common AntiPattern and offering detailed solutions. Until now, this information was difficult to find - and much of it wasn't available at all. Using Rails AntiPatterns, developers can dramatically improve the quality of both new and existing Rails applications; avoid future bad practices; and establish more effective Rails coding standards throughout the development organization.
