Eloquent Ruby

It’s easy to write correct Ruby code, but to gain the fluency needed to write great Ruby code, you must go beyond syntax and absorb the “Ruby way” of thinking and problem solving. In Eloquent Ruby, Russ Olsen helps you write Ruby like true Rubyists do–so you can leverage its immense, surprising power.

Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the “Ah Ha!” moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language’s elegance and expressiveness.

Eloquent Ruby starts small, answering tactical questions focused on a single statement, method, test, or bug. You’ll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for.

Next, the book addresses bigger questions related to building methods and classes. You’ll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code–and why you’ll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages.

A part of the renowned Addison-Wesley Professional Ruby Series, Eloquent Ruby will help you “put on your Ruby-colored glasses” and get results that make you a true believer.

—Peter Cooper, editor of Ruby Inside

Very detailed and hands-on Rails Tutorial!

Great job! I’m learning Rails, and found your tutorial to be one of the most detailed and hands-on guides. Besides many details of Rails, it also taught me about Git, Heroku, RSpec, Webrat, and most important (at least to me), it emphasized the Test-Driven Development (TDD) methodology. I learned a lot from your tutorial. Keep up the good job! Thanks so much for sharing it.

—Albert Liu, senior manager, Achievo Corporation.

Ruby on Rails Tutorial is the best!

Just wanted to say that your Ruby on Rails tutorial is the best! I’ve been trying for a while to wrap my head around Rails. Going through your tutorial, I’m finally feeling comfortable in the Rails environment. Your pedagogical style of gradually introducing more complex topics while at the same time giving the reader the instant gratification and a sense of accomplishment with working examples really works for me. I also like the tips and suggestions that give me a sense of learning from a real Rails insider. Your e-mail response to a problem I ran into is an example of your generous sharing of your experience.

—Ron Bingham, CEO, SounDBuytz

Ruby on Rails 3: Das Entwickler-Handbuch

Das Buch von Hussein und Tanja „Ruby on Rails 3: Das Entwickler-Handbuch“ erscheint im April in einer neuen und aktualisieren Version.

Einiges hat sich getan: Rails 3 integriert das Ruby-Framework »Merb« und erweitert damit enorm sein Potenzial. Die neue Version bietet so eine viel größere Flexibilität bei der Wahl des Datenbank-, Test- und Template-Frameworks. Die zahlreichen und komplexen Möglichkeiten des Frameworks werden ausführlich behandelt. Dabei bleibt das Buch stets verständlich und praxisbezogen, da Rails anhand mehrerer »Realworld«-Beispiele anschaulich erläutert wird. Alle Beispielapplikationen sind dabei systematisch aufgebaut: von einer einfachen bis zu einer komplexen Anwendung inklusive TestDrivenDevelopment. Tipps und Tricks, eine umfassende Befehlsreferenz und eine Einführung in die Sprache Ruby lassen dann keine Wünsche mehr offen.

The Rails 3 Way

Ruby on Rails strips complexity from the development process, enabling professional developers to focus on what matters most: delivering business value via clean and maintainable code. The Rails™ 3 Way is the only comprehensive, authoritative guide to delivering production-quality code with Rails 3. Pioneering Rails expert Obie Fernandez and a team of leading experts illuminate the entire Rails 3 API, along with the idioms, design approaches, and libraries that make developing applications with Rails so powerful. Drawing on their unsurpassed experience and track record, they address the real challenges development teams face, showing how to use Rails 3 to maximize your productivity.

Using numerous detailed code examples, the author systematically covers Rails 3 key capabilities and subsystems, making this book a reference that you will turn to again and again. He presents advanced Rails programming techniques that have been proven effective in day-to-day usage on dozens of production Rails systems and offers important insights into behavior-driven development and production considerations such as scalability. Dive deep into the Rails 3 codebase and discover why Rails is designed the way it is—and how to make it do what you want it to do.

This book will help you

Praise for the Previous EditionThis encyclopedic book is not only a definitive Rails reference, but an indispensable guide to Software-as-a-Service coding techniques for serious craftspersons. I keep a copy in the lab, a copy at home, and a copy on each of my three e-book readers, and it’s on the short list of essential resources for my undergraduate software engineering course.

—Armando Fox, adjunct associate professor, University of California, Berkeley

Everyone interested in Rails, at some point, has to follow The Rails Way.

—Fabio Cevasco, senior technical writer, Siemens AG, and blogger at H3RALD.com

I can positively say that it’s the single best Rails book ever published to date. By a long shot.

—Antonio Cangiano, software engineer and technical evangelist at IBM

This book is a great crash course in Ruby on Rails! It doesn’t just document the features of Rails, it filters everything through the lens of an experienced Rails developer—so you come our a pro on the other side.

—Dirk Elmendorf, co-founder of Rackspace, and Rails developer since 2005

The key to The Rails Way is in the title. It literally covers the “way” to do almost everything with Rails. Writing a truly exhaustive reference to the most popular Web application framework used by thousands of developers is no mean feat. A thankful community of developers that has struggled to rely on scant documentation will embrace The Rails Way with open arms. A tour de force!

—Peter Cooper, editor, Ruby Inside

In the past year, dozens of Rails books have been rushed to publication. A handful are good. Most regurgitate rudimentary information easily found on the Web. Only this book provides both the broad and deep technicalities of Rails. Nascent and expert developers, I recommend you follow The Rails Way.

—Martin Streicher, chief technology officer, McLatchy Interactive; former editor-in-chief of Linux Magazine

Hal Fulton’s The RubyWay has always been by my side as a reference while programming Ruby. Many times I had wished there was a book that had the same depth and attention to detail, only focused on the Rails framework. That book is now here and hasn’t left my desk for the past month.

—Nate Klaiber, Ruby programmer

As noted in my contribution to the Afterword: “What Is the Rails Way (To You)?,” I knew soon after becoming involved with Rails that I had found something great. Now, with Obie’s book, I have been able to step into Ruby on Rails development coming from .NET and be productive right away. The applications I have created I believe to be a much better quality due to the techniques I learned using Obie’s knowledge.

—Robert Bazinet, InfoQ.com, .NET and Ruby community editor, and founding member of the Hartford, CT, Ruby Brigade

Extremely well written; it’s a resource that every Rails programmer should have. Yes, it’s that good.

—Reuven Lerner, Linux Journal columnist

The Rails™ 3 Way is a comprehensive resource that digs into the new features in Rails 3 and perhaps more importantly, the rationale behind them.
—Yehuda Katz, Rails Core

Ruby on Rails 3: Moderne Webentwicklung mit Ruby

Ruby on Rails ist eines der beliebtesten Frameworks im Bereich der Webentwicklung. Einer der Hauptgründe dafür ist die geringe Einarbeitungszeit, da das Model-View-Controller-Konzept (MVC) klar zu erkennen ist. Ruby on Rails gibt uns sehr schnell Feedback über das Ergebnis unserer Arbeit, wodurch die Entwicklung von Webanwendungen sehr viel Spaß mit sich bringt.

Ruby on Rails wurde von David Heinemeier Hansson bei der Entwicklung von Basecamp extrahiert und erblickte im Juli 2004 das Licht der Open-Source-Welt. Mit der Zeit hat sich eine gigantische Community und ein Core Team, welches die Entwicklung koordiniert, um das Projekt gebildet. Ruby on Rails wird mit der Version 3 erwachsen und fit für den Enterprise Bereich. Den Autoren Michael Voigt und Stefan Tennigkeit – selbst Ruby-Entwickler – gelang es, das komplexe Themengebiet unter dem Aspekt der praktischen Umsetzung in verständlicher Art und Weise zu beschreiben. Das eigene Fachwissen sowie die persönlichen Erfahrungen der Autoren im Umgang mit Ruby on Rails werden durch zahlreiche Abbildungen, Tabellen und Quelltext-Beispiele einer produktiv gestellten Webanwendung (www.kraeftemessen.com) ergänzt. Durch diese deutliche Praxisorientierung schaffen es die Autoren anhand von alltagspraktischen Anwendungsfällen, Themen wie beispielsweise HAML und SASS, Release- und Sourcecode-Management mit Capistrano, Test Driven Development, Volltextsuche mit Sphinx, Geokoordinaten inhaltlich und methodisch zu verdeutlichen.
