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

from rest_framework import viewsets
from .models import Product
from .serializers import ProductSerializer


class ProductViewSet(viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer

Let's Consider Each Line Separately

class ProductViewSet(viewsets.ModelViewSet):

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.

queryset = Product.objects.all()

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

serializer_class = ProductSerializer

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.
