This tutorial outlines the process of building and deploying a Django REST API, covering the entire workflow from project initialization to deployment on Heroku. It begins with creating a new Django project and app, setting up a database, and configuring the Django Rest Framework for JSON serialization. The guide details creating serializers, views, and URL patterns, as well as enabling pagination and configuring installed apps. Deployment involves preparing a Git repository, creating necessary configuration files, and pushing the project to Heroku, including setting up a PostgreSQL database and configuring environment variables. Finally, the tutorial culminates by adding the API to the RapidAPI marketplace, allowing for further enhancement and integration.
