Crafting Rails 4 Applications: Expert Practices for Everyday Rails Development (The Facets of Ruby)

If you've got some experience with basic Rails apps and want to go deeper, this book is an excellent resource. It walks through some of the more advanced concepts in Rails, like how to make a plugin or gem, how ActiveRecord works, how to write good tests and use TDD, and how to use responders in your controllers.The book handles these fairly sophisticated topics with more clarity than just about any resource I've found elsewhere, showing not only how to work with the toolset and optimize your code, but also why these tips matter. It's fairly short, and it left me wanting more, though I do feel like I got my time and money's worth out of it. But so far, this is the best intermediate-level book I've found on Rails 4.

Goes very in-depth into the inner workings of Rails and how you can customize your applications needs in any scenario. Great book by José, I highly recommend.

This book offers great topics and all the chapters carries great additional content besides its main topic. Awesome and easy read.

If you are looking for expert knowledge on rails development. This is the book for you.

The Author of the book expects reader to be experienced with Ruby language and Rails framework. There are no elementary explanations of how to do basic stuff like you will find in Beginning Rails and similar sort of books. Every reader should consider this before reading this book.The book takes reader deeper into Rails framework, explains how framework works by using diagrams and parts of Rails source codes. What I really liked was that explanations do not end here, but they are more like starting point for further learning. For example author describes how rendering stack in Rails works and then tries to learn reader how to write custom renderers, template handlers, responders, etc. In many cases via Rails plug-ins.What I consider as one of the strong points of book is that author tends to use TDD when implementing examples. It can help and inspire reader to try TDD in real life situations.It may be just me, but chapters usually consist of more than 20 pages and examples are scattered on many pages, which was sometimes really confusing. To not lose track of what's going on, I found useful to have all code samples in computer and play with them after I finished chapter or during reading.To sum up, I really enjoyed reading this book (it's around 200 pages, I would gladly read more 100 pages), it was not boring, I would highly recommend this book.

This book is for an advanced developers. I bought the book from pragprog and it was a mistake. I liked Programming Ruby and Ajile development from them so much that I thought that this book will be similar. It is not. The samples did not work for me. I use Cloud 9 environment. I did not want to spend more time solving constant configuration problems. In my opinion it is obsolete and needs new revision to cater for new software releases.

The only Rails book I ever regretted shelling out the money for. The author doesn't adequately explaine the problem(s) he is trying to solve and assumes a level of knowledge on the subject that is not trivial.
