Python Django – Connecting a Postgres Database

To connect a PostgreSQL database in Python Django, follow these steps:
1. Install the required dependencies: Install the psycopg2 package, which is a PostgreSQL adapter for Python, by running pip install psycopg2.
2. Configure the database settings: Open your Django project’s settings.py file and locate the DATABASES dictionary. Update the ENGINE value to django.db.backends.postgresql’. Set the NAME to the name of your PostgreSQL database, USER and PASSWORD to the credentials of your database user, and HOST and PORT to the host and port where your PostgreSQL server is running.
3. Test the connection: Run the Django development server with the command python manage.py runserver. Django will attempt to connect to the PostgreSQL database using the provided configuration. If the connection is successful, you should see no errors in the console.
