This is a great book about the internals of Rails! I learned a bunch of how to use some pieces together to create better applications. This book changed my view that Rails is too much coupled: it is much more flexible than I thought. Highly recommended for those who want to learn more about Ruby on Rails and its internals.

Must read if you want to see under the hood of Rails, definitely not book to learn Rails from, I'd recommend book to every intermediate Rails developer.
Really advanced stuff for people who are ready and itching to dig into Rails internals.

The examples were a bit too contrived for my taste. Several didn't have any reason to exist other than to show off the guts of Rails, and the author even admitted that you'd have been more likely to solve a problem in a more straightforward, simple manner.

It's information-dense enough that I found it to be kind of a slog, though I did like the way chapters were organized, tying several deep Rails concepts into

Excellent book. José Valim makes some pretty advanced stuff look simple, not least by test driving his way through the book. Recommended for anyone who want to create Rails engines, renderers, generators or similar, and for anyone who simply want to know more about the internals of Rails. It's a quick read but each page contains valuable stuff, there are no boring passages.

The table of contents is a bit misleading because most chapters actually cover a lot more than the main topic.

The most interesting book about Rails internals. The author (Jose Valim) has an excellent understanding of Rails internals and infrastructure and does a great job to break down and simplify the advanced concepts. I highly recommend this book to Rails intermediate developers who want to write their own plugins or gems.

The book covers Rails for intermediate programmes and offers many useful insights. Unfortunately it didn’t caught my interest. Rails 4 in Action is more my kind of book when it comes to Rails 4.

If you want to know about Rails internals, this is your book. Some of the examples are not recipes that you'll ever directly need, but the explanation shows many interesting details. Other books are nothing but sugar on top of the official tutorials. This one digs much deeper.

There aren't many "advanced" Rails books around, but this one is an exception. It would perhaps have been even greater if organized around Rails topics (how routing works, rails views etc.) instead of having a "walkthrough" style creating useful ruby gems.

An interesting read which delves into rails internals. While I found the information hidden in this book quite valuable, it was a bit rambly and the examples were a bit contrived. I feel it could have been 100 pages shorter and still held the same value.
Xavier Shay
Good reference if you want to go anywhere near the Rails APIs with plugins.

Shelves: programming, 2015
Getting your feet wet in different parts of the Rails stack in a super fast tracked pace. It can be a little out of context, but it makes up for that by trying to touch upon a lot of topics
It is not easy book.
It is really deep book on Rails internals. It helped me understand responders and translations in Rails.
I used techniques I found in book in current projects
