About this course

Writing repetitive code for standard CRUD operations can make your Ruby on Rails applications difficult to maintain and scale. By learning how to systematically apply the Don't Repeat Yourself (DRY) principle, you can transform bloated codebases into elegant, clean architectures. This text-only course guides you through refactoring your Rails controllers, views, and routes, helping you write cleaner code that is easier to test and extend. What you'll learn: - Understand core DRY principles and how they specifically apply to standard Rails MVC patterns. - Refactor redundant controller actions using modern Rails concerns, callbacks, and helper methods. - Streamline views with reusable partials, layout templates, and modern helper patterns. - Simplify routing structures using nested resources and shallow routing conventions. - Write clean tests to ensure your refactored code maintains identical functionality. - Practice identifying code smells in typical CRUD operations through structured reading exercises. You will start with foundational definitions of code duplication and standard Rails conventions. From there, you will work through step-by-step refactoring examples, starting with simple controller cleanups and moving to advanced view optimization techniques. This course is designed for beginner to intermediate Rails developers who understand basic CRUD operations and want to level up their code quality. No advanced refactoring experience is required. Start reading today to make your Rails applications cleaner, faster, and easier to maintain.
