Introduction: The Architecture of a Modern Sports Platform When building a high-performance backend like the AI Soccer App , the primary challenge isn't just "making it work"—it's making it scalable, secure, and maintainable. In a project that handles everything from AI-driven team analytics to complex Multi-Factor Authentication (MFA), the way you structure your API determines how easily you can add features six months from now. In this article, we will use our AI Soccer App as a living case study to explore the two primary philosophies of API building in Django: the Explicit Action Pattern (using APIViews) and the Resource Management Pattern (using ViewSets and Routers). Part 1: The Explicit Action Pattern (The Authentication Case Study) In our apps/users/ directory, we chose not to use automated routers. Instead, we manually defined every path in urls.py . To understand why, we have to look at the nature of authentication. Why APIViews for Auth?…
