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
from rest_framework import viewsetsfrom .models import Productfrom .serializers import ProductSerializerclass 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
.
