Building Social Media Like Features with Django and REST Framework

Adding interactive elements like post reactions is a fundamental requirement for modern web applications, yet implementing them efficiently requires a solid understanding of database relationships and API design. This course guides you through the process of building a robust and scalable like feature for social media posts. You will start by understanding the foundational database concepts and relationships needed to support user interactions without slowing down your application. By completing this text-only course, you will be able to design clean database models, write efficient queries, and expose secure endpoints for user interactions. What you'll learn: - Understand the foundational database relationships and model structures for user interactions - Create Django models to represent posts, users, and likes with appropriate unique constraints - Build REST API endpoints using serializers to handle like and unlike actions cleanly - Implement optimized database queries to prevent common performance bottlenecks like the N+1 problem - Apply basic authentication and permission checks to ensure only authorized users can interact with posts - Write unit tests to verify the reliability and correctness of your interaction endpoints We begin with essential architectural concepts, explaining how to structure database tables for social interactions. From there, you will progress through hands-on coding exercises, writing Django models, configuring serializers, and implementing optimized API endpoints step-by-step. This course is designed for beginner to intermediate Python developers who are familiar with basic Django concepts and want to learn how to build real-world, interactive API features. No advanced database experience is required. Start building interactive social features for your web applications today.
