## Overview

Build comprehensive Django web applications with proper model design, view hierarchies, database operations, user authentication, and admin functionality following Django conventions and best practices.

## When to Use

- Creating Django web applications
- Designing models and database schemas
- Implementing views and URL routing
- Building authentication systems
- Using Django ORM for database operations
- Creating admin interfaces and dashboards

## Quick Start

Minimal working example:

```bash
django-admin startproject myproject
cd myproject
python manage.py startapp users
python manage.py startapp products
```

## Best Practices

### ✅ DO

- Use models for database operations
- Implement proper indexes on frequently queried fields
- Use select_related and prefetch_related for query optimization
- Implement authentication and permissions
- Use Django Forms for form validation
- Cache expensive queries
- Use management commands for batch operations
- Implement logging for debugging
- Use middleware for cross-cutting concerns
- Validate user input

### ❌ DON'T

- Use raw SQL without ORM
- N+1 query problems without optimization
- Store secrets in code
- Trust user input directly
- Override **init** in models unnecessarily
- Make synchronous heavy operations in views
- Use inheritance models unless necessary
- Expose stack traces in production
