Creating Long-Lived Web Apps with Ruby on Rails
Gain insights into creating Rails apps by focusing on consistency and best practices. Discover techniques for managing business logic, testing, and improving code quality without complex patterns.
Ruby on Rails is a server-side web development framework. Are you an experienced Rails developer but struggle with managing the complexity your Rails apps acquire over time? You don’t need gems or complicated design patterns; you just need to focus on consistency, sustainability, and the best parts of Rails.
In this course, you’ll learn straightforward techniques to apply to each Rails part, from routes to views to controllers to Active Records. You’ll learn to put business logic in separate Ruby classes that you can manage outside of Active Record, plus how these classes fit into Rails. You’ll also learn testing techniques for reliable system tests and useful unit tests.
After taking this course, you’ll have a pragmatic list of techniques you can apply to any Rails project and a clear foundation for why these techniques work. You can write better Rails code and share the benefits with coworkers and colleagues.
