A guide to building applications with Rails covers such topics as metaprogamming, Active Support library, advanced database functions, security principles, RESTful architecture, and optimizing performance."Advanced Rails explores topics that separate leading-edge Rails programmers from the masses. You get an in-depth look at techniques for dealing with databases, security, performance, web services, and much more with this unique bottom-up approach to Rails. Written in a clear ancl engaging style, this book helps you understand not only the tricks and techniques used within Rails itself, but also how to make use of ideas borrowed from other programming paradigms. Advanced Rails pays particular attention to building applications that scale-whether "scale" means handling more users or working with a bigger and more complex database." "Advanced Rails also explores how to extend Rails, use individual Rails components in other Ruby code, internationalize your application, and more. In addition, each detailed chapter includes resources for further reading. If you're ready to improve your skills with Rails through advanced techniques, this is the book you need."--BOOK JACKET.
