Django Framework Guide

Applies to: Django 5+, Django REST Framework, Django Channels Language: Python 3.10+

Core Principles

1. Batteries Included: Leverage Django's built-in features before adding third-party packages
2. DRY: Don't Repeat Yourself -- use abstract models, mixins, and shared utilities
3. Fat Models, Thin Views: Keep business logic in models and services, not views
4. Explicit Over Implicit: Use clear URL patterns, explicit imports, named relationships
5. Security by Default: CSRF, XSS protection, SQL injection prevention are built in
