“When I read The Rails Way for the first time, I felt like I truly understood Rails for the first time.”—Steve Klabnik, Rails contributor and mentor

The Rails™ 6 Way is the comprehensive, authoritative reference guide for professionals delivering production-quality code using modern Ruby on Rails. It illuminates the entire Rails 6 API, its most powerful idioms, design approaches, and libraries. Building on the previous editions, this edition has been heavily refactored and updated. It features entirely new chapters on Action Mailbox, Action Text, Active Storage, Multi Database Support and Webpacker.

Through detailed code examples, you’ll dive deep into Ruby on Rails, discover why it’s designed as it is, and learn to make it do exactly what you want. Proven in thousands of production systems, the knowledge in this book will maximize your productivity and help you build more successful solutions.
