A step-by-step guide to building a custom decorator pattern implementation in Ruby from scratch. The tutorial covers creating a basic decorator class, implementing method delegation using Ruby's method_missing, abstracting the behavior into a reusable ApplicationDecorator, and finally leveraging Ruby's SimpleDelegator for a cleaner solution. The decorator pattern helps separate view-related logic from models by wrapping objects and adding presentation methods while maintaining access to the original object's functionality.
