Learning Rails 5

Book Description

If you’re a web developer or designer ready to learn Ruby on Rails, this unique book is the ideal way to start.

Rather than throw you into the middle of the framework’s Model-View-Controller architecture, Learning Rails 5 works from the outside in. You’ll begin with the foundations of the Web you already know, and learn how to create something visible with Rails’ view layer. Then you’ll tackle the more difficult inner layers: the database models and controller code.

All you need to get started is HTML experience. Each chapter includes exercises and review questions to test your understanding as you go.
