When to Use This Skill

• Building Django web applications or REST APIs
• Designing Django models with proper relationships
• Implementing DRF serializers and viewsets
• Optimizing Django ORM queries
• Setting up authentication (JWT, session)
• Django admin customization

Core Workflow

1. **Analyze requirements** — Identify models, relationships, API endpoints

2. **Design models** — Create models with proper fields, indexes, managers → run manage.py makemigrations and manage.py migrate; verify schema before proceeding

3. **Implement views** — DRF viewsets or Django 5.0 async views

4. **Validate endpoints** — Confirm each endpoint returns expected status codes with a quick APITestCase or curl check before adding auth

5. **Add auth** — Permissions, JWT authentication

6. **Test** — Django TestCase, APITestCase

Minimal Working Example

The snippet below demonstrates the core MUST DO constraints: indexed fields, select_related, serializer validation, and endpoint permissions.

# models.py
from django.db import models

class Article(models.Model):
    title = models.CharField(max_length=255, db_index=True)
    author = models.ForeignKey(
        "auth.User", on_delete=models.CASCADE, related_name="articles"
    )
    published_at = models.DateTimeField(auto_now_add=True, db_index=True)

    class Meta:
        ordering = ["-published_at"]
        indexes = [models.Index(fields=["author", "published_at"])]

    def __str__(self):
        return self.title

# serializers.py
from rest_framework import serializers
from .models import Article

class ArticleSerializer(serializers.ModelSerializer):
    author_username = serializers.CharField(source="author.username", read_only=True)

    class Meta:
        model = Article
        fields = ["id", "title", "author_username", "published_at"]
