Django ORM Deep Dive

A hands-on repo for exploring the Django ORM in depth — querysets, relations, annotations, and API-backed examples to build a solid intuition for how Django talks to the database.

Setup

git clone https://github.com/rohan9932/django-orm-deep-dive.git
cd django-orm-deep-dive
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python manage.py migrate
python manage.py runserver

What this covers

• Queryset basics: filtering, chaining, Q objects
• Relations: ForeignKey, OneToOne, ManyToMany and related lookups
• Annotations and aggregation (annotate, aggregate, F expressions)
• select_related / prefetch_related and query optimization
• Exposing ORM queries through a small DRF API for hands-on testing

Notes

This is a learning/practice repo — not a production project.
