Tutorial vs Reality

Building a real-world system teaches you way more than theoretical tutorials. 🧠 Today I spent time mapping out a backend architecture for a booking system using Ruby. On paper, most systems seem simple: you have resources, users, and interactions. But when you start coding the actual logic, the real puzzles appear:

How do you gracefully validate bad user inputs? Where should confirmation logic live — inside the resource object or the manager class?

Figuring out Single Responsibility Principle (SRP) boundaries in a domain model is a muscle you can only train by building things from scratch. No tutorial prepares you for the moment you realize your method is doing too much, or that your object knows things it shouldn’t. That clarity only comes from actually writing the code. 💡 #Ruby #BackendDevelopment #LearnByDoing #SoftwareDesign #OOP
