Rails 5 Way, The (Addison-Wesley Professional Ruby Series) 4th Edition

Great book for those with a general understanding of Rails. It gave me a much deeper and thorough understanding of Rails 5. The author demonstrates an in-depth knowledge of how Rails works and sprinkles in viewpoints from others that add really useful perspective.

You need to already know how things work in Rails, but this book is an amazing reference for all that is possible at every step of the way.

One of the best ruby books

It’s a really good book for deep dives in various parts of the framework. My only gripe is they went with haml and I feel like if you are writing a rails way book, you shouldn’t inject your opinion but just give the info on what the framework provides. Not sure why they did that and it’s a big enough issue to me that I would leave this at 3.5 stars if I could, but the rest was good enough to round up.

I wasn't terribly disappointed by this book. It probably merits a four-star review, but I wanted to call out that it's not adding a lot of value over and above what you'd get by just reading the Rails documentation and the READMEs for various plugins. This book and its predecessors get a ton of five-star reviews. After reading them, it's not clear why. The premise of the book is very promising—a tour of Rails for intermediate to advanced users of the platform. I'm not sure that it lives up to this promise. Many of the chapters seem 100% introductory. Some of the chapters (e.g. Turbolinks) almost seem to mimic the content of the corresponding plugin's README text.There are a handful of insights and techniques in here, but those are in the margins. This is largely an introductory work. I was surprisingly disappointed. My hope was to see more content about maintaining Rails applications, architecture and design patterns. I would have expected more case studies and fewer introductions to syntax.
