Here's a simple example that utilizes Django REST framework.
To get it running:
pip install -r requirements.txt
python manage.py makemigrations
python manage.py migrate
python manage.py createsuperuser
python manage.py runserver
The API can be reached at http://127.0.0.1:8000/api/cars
New users can be created within the Django admin page: http://127.0.0.1:8000/admin/auth/user/
