How can I connect my existing external PostgreSQL Database to automatically create my Models.py for a Django Rest Framework?

I have an existing PostgreSQL Database and I want to create APIs around it using Django Rest Framework. How do I display the tables in my Database as models in Django to further use them for the API?

First of all, you have to connect the existing DB with your Django application by following those instructions https://docs.djangoproject.com/en/3.1/ref/databases/#postgresql-notes or simply add the code below in your settings.py file

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'db_name',                      
        'USER': 'db_user',
        'PASSWORD': 'db_user_password',
        'HOST': '',
        'PORT': 'db_port_number',
    }
}

Secondly, Django provides a powerful command which will help you out to inspect your existing DB models and save those models into your models.py file.

python manage.py inspectdb > models.py

In case that you need more information please read the official documentation https://docs.djangoproject.com/en/3.1/howto/legacy-databases/#auto-generate-the-models.
