Django REST Framework

1. What is the Rest API ?

We begin by understanding the fundamental concepts of RESTful API architecture, comparing Django to Django Rest Framework (DRF), and exploring JSON formatting. We'll also discuss the latest trends in web development and guide you through the installation and project setup process.

2. What is Serialization?

Serialization is a crucial aspect of building APIs. Here, we'll dive deep into serialization, exploring its importance, discussing various models, and understanding serializers in Django Rest Framework. Additionally, we'll cover built-in serializers for efficiency.

3. Views and Routers

Next, we'll explore views and routers in DRF. We'll cover class-based views, their significance, and the built-in views provided by Django Rest Framework. Routers play a vital role in API routing, and we'll provide a comprehensive overview of how to utilize them effectively with DRF's API router.

4. HTTP Request Methods

Understanding HTTP request methods is essential for building robust APIs. We'll cover GET, POST, PUT, and DELETE methods, along with their practical applications. Additionally, we'll discuss HTTP response status codes and their significance in API development.

Overview of View

In this chapter, we'll discuss creating a new view for our Django Rest Framework project. This view will be responsible for working with Product model objects and providing standard CRUD (Create, Read, Update, Delete) operations. We'll examine each line of code individually to better understand its purpose and interaction with other Django Rest Framework components.

Adding a View to Our Project

AppFolder\views.py

Let's Consider Each Line Separately

Defines a new class ProductViewSet that inherits from the ModelViewSet class provided by Django Rest Framework. ModelViewSet provides typical CRUD (Create, Read, Update, Delete) operations for Django models.

Defines a queryset, which is a collection of database queries, including all objects of the Product model.

Specifies the serializer class to be used for serialization and deserialization of model objects. In this case, ProductSerializer is used.

Thus, the ProductViewSet class creates an API for interacting with objects of the Product model, providing standard CRUD operations, as well as the ability to serialize and deserialize data using ProductSerializer.
