Django

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Django 5.0 (2025) introduces database-computed default values and expanded async support.

When to Use

• Perfectionists with deadlines: The "batteries-included" philosophy means Auth, Admin, and ORM are ready day one.
• Data-Driven Apps: The Django Admin is still the best auto-generated admin interface in the industry.
• Enterprise: Security features (CSRF, SQL Injection protection) are best-in-class.

Quick Start

# models.py
from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=200)
    # New in 5.0: Database generated field
    slug = models.GeneratedField(
        expression=models.functions.Concat(models.F("title"), models.Value("-slug")),
        output_field=models.CharField(max_length=205),
        db_persist=True,
    )

Core Concepts

MTV Architecture

Model (Data), Template (Presentation), View (Business Logic).

The ORM

Powerful abstraction over SQL. Post.objects.filter(pub_date__year=2025).

Async Django

Django 5 supports async views, ORM calls (aget_object_or_404), and Auth methods (alogin).

Best Practices (2025)

Do:

• Use GeneratedField: Let the database handle computed columns instead of Python properties for better performance.
• Use Async Views: For I/O bound tasks (calling external APIs), use async def view(request):.
• Use django-ninja: For building APIs, it's faster and cleaner than DRF (Django Rest Framework) and uses Pydantic.

Don't:

• Don't put logic in templates: Keep templates dumb. Put logic in Models or Services.
