Ruby on Rails Tutorial: Learn Web Development with Rails, 3/e(Paperback)

Michael Hartl



Ruby on Rails™ Tutorial by Michael Hartl has become a must-read for developers learning how to build Rails apps.”

—Peter Cooper, Editor of Ruby Inside


Used by sites as diverse as Twitter, GitHub, Disney, and the Yellow Pages, Ruby on Rails is one of the most popular frameworks for developing web applications, but it can be challenging to learn and use. Whether you’re new to web development or new only to Rails, Ruby on Rails™ Tutorial, Third Edition, is the solution.


Best-selling author and leading Rails developer Michael Hartl teaches Rails by guiding you through the development of three example applications of increasing sophistication, focusing on the fundamental techniques in web development needed for virtually any kind of application. The updates to this edition include simplified installation via a standard development environment in the cloud, use of the default Rails stack throughout, a light-weight testing approach, an all-new section on image upload, and an all-new chapter on account activation and password resets, including sending email with Rails.


This indispensable guide provides integrated tutorials not only for Rails, but also for the essential Ruby, HTML, CSS, and SQL skills you’ll need when developing web applications. Hartl explains how each new technique solves a real-world problem, and then he demonstrates it with bite-sized code that’s simple enough to understand, yet novel enough to be useful. Whatever your previous web development experience, this book will guide you to true Rails mastery.
