Ruby on Rails is a young, lean framework focused on developer productivity and happiness. The chief reason for Rails’s growing popularity is the ability to rapidly build, enhance, and scale websites and web services thanks to its cutting-edge design, human-readable syntax, and open ethos of sharing your ideas with others. Working in Rails makes you part of a larger community of forward-thinking programmers advancing the vanguard of web technology.

This book focuses on Rails fundamentals, including a primer on the Ruby programming language. A strong emphasis is placed on best practices and the Model-View-Controller (MVC) paradigm. By the end of the first chapter, you’ll have built a fully-functioning Rails website, and by the end of the book, you will have had a tour through the major components of Rails.

The Best Way to Enjoy Our Books

Our workbooks are meant to be used while you work on your computer. They typically contain step-by-step exercises that walk you through doing tasks on your computer. An ideal setup would be to have the eBook loaded onto a device (like a tablet/smartphone) or on a second computer monitor, so you can read the book as you work on your computer. You can also print the PDF if you prefer.

Which File Format Is Right for You?
PDF
  • Ideal for printing.
  • An exact match to the printed book. If the text reflow of an EPUB or MOBI file is confusing please refer to the PDF.
  • PDF is compatible with most devices, but it’s not optimized for small screens. If using a smaller screen you’ll likely want to use the EPUB or MOBI files.
EPUB
  • The industry standard eBook format which works with all devices, except for the Amazon Kindle. EPUB can be read on Mac, PC, iPhone, iPad, iPod Touch, Nook, Sony Reader, Kobo, Android, and many more.
  • Ideal for smaller screens as the layout reflows to fit the current device (at the type size of your choice).
MOBI (Kindle)
  • Amazon’s format for Kindle devices and Kindle app.
  • Ideal for smaller screens as the layout reflows to fit the current device (at the type size of your choice).
  • Using an iOS Device such as iPhone & iPad? The Kindle app for Apple iOS devices requires a specialized format which we do not support. While our MOBI will work in the Kindle app, it will not render well on iOS devices. We recommend using the EPUB format with Apple’s iBooks app if reading on an iOS device.

Can You Share the eBook or Printouts?

Noble Desktop books are intended for use by you, the owner. They are not intended to be loaned or given to others. The files are subtly watermarked with your name and email, but we do not apply any DRM. You can copy your eBooks to any of your own devices without restriction. You can print the PDF files for your own use, but not to give to others. You cannot sell used eBooks. Ownership is solely yours and cannot be transferred.

Teachers and training centers wishing to print copies for students should email for licensing options and pricing.

How It Works
  • When you buy an eBook for yourself, it will be added into your account. It will be watermarked with your information and is intended for use only by you.
  • You can also purchase eBooks for someone else, such as a friend or colleague. Schools and training centers can purchase eBooks for their students (be sure to apply for educational pricing).
  • When buying eBooks for someone else, you will receive an eBook voucher code to share with them. Send that code to the recipient and they will be able to redeem it. An eBook voucher code can be redeemed once, for the specific book you purchase for them.
  • The recipient of the eBook voucher code will need to log into their Noble Desktop account, or create a free account. In their account they will enter the code (in the My eBooks tab) and the eBook will be added immediately into their account.
  • The recipient receives all the same benefits of Noble Desktop eBooks, which includes lifetime access to download their eBook, as well as free updates to that edition. When the next edition is released, an affordable upgrade option will be available to them.

Examples of What You Learn

  • Build a Rails project that manages movie information and reviews.

  • Learn the principles of MVC (Model, View, Controller) and model management.

  • Create forms in Rails for easily updating models.

  • Learn how to route requests and display dynamic content
    in custom templates.

  • Use Ruby Gems: plugins that extend the functionality of Rails.

Why Our Books Are Unique

Our books are packed with step-by-step exercises that walk you through projects. You’ll learn by doing exercises, not reading long explanations commonly found in user manuals. The goal is to give you hands-on practice with the program, getting you started quickly with the things that are most important for real life work. Our books are not a replacement for the manual, but manuals aren’t how you learn an app!
