If you are a developer who is already familiar with the basics of the Rails framework and have previously worked with Rails 3.2 or earlier, then this is the ideal book for you. It is assumed that you have some prior experience with the development of applications. This book will help you to upgrade your existing knowledge and also ensure its applicability.

In Detail

Rails is a rapidly moving, open source, web development framework, and keeping up to speed with it is a big task. You might have already built applications using it, but there have been significant changes in the syntax and semantic of the Rails framework in the latest upgrade.

Rails 4 Application Development Hotshot shows you how to build the most popular types of applications using Rails 4, and highlights new ways to do things. The book also closely follows lots of the best practices, gems, and popular solutions already known to the community, and tracks the changes in these. This book brings new ideas to refactor and restructure code to make it perform better in production, and enables you to write production-ready code.
