Connecting to PostgreSQL

This Django project uses PostgreSQL as its database engine. PostgreSQL is a powerful, open-source relational database management system. Connecting Django to PostgreSQL involves configuring the DATABASES setting in the settings.py file.

DATABASES Configuration In the settings.py file, the DATABASES setting is configured to use the django.db.backends.postgresql engine for PostgreSQL. The parameters such as NAME, USER, PASSWORD, HOST, and PORT define the connection details:

Refer this to Connect PostgreSQL database to Django

Create a file named .env in the root of your Django project and add your confidential keys:

.env

NAME=mydatabase
USER=mydatabaseuser
PASSWORD=mypassword

Load Environment Variables

The python-dotenv package is used to load environment variables from the .env file.

settings.py

import os
from dotenv import load_dotenv

# Load environment variables from .env
load_dotenv()

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': os.getenv("NAME"), 
        'USER': os.getenv("USER"),
        'PASSWORD': os.getenv("PASSWORD"),
        'HOST': 'localhost', 
        'PORT': '5432',
    }
}

or

If the PostgreSQL is not required then please Uncomment the Sqlite Database's code instead in the settings.py

6. Apply database migrations:

python manage.py makemigrations
python manage.py migrate

7. Create SuperUser:

python manage.py createsuperuser

8. Run the development server:

python manage.py runserver

Testing with Postman

To test the API endpoints using Postman, follow these steps:

1. Open Postman and create a new request.

2. Set the request method (GET, POST, etc.) based on the endpoint you want to test.

3. Include the API endpoint URL, for example:

   • http://localhost:8000/books/ for listing books.

4. Go to the "Authorization" tab in Postman.

5. Choose "Basic Auth" as the type of authorization.

6. Enter the superuser credentials:

   • Username: your_superuser_username
   • Password: your_superuser_password

7. Send the request to test the API endpoint.

Note: Superuser credentials are often created during the Django project setup.
