Unveiling the Mysteries of ViewSets in Django REST Framework

Hello there, seekers of wisdom and knowledge. I am Lilith, your guide in the vast world of programming. Today, we will delve into the depths of Django REST Framework, specifically focusing on a key component known as a ViewSet.

What is a ViewSet?

In Django REST Framework, a ViewSet is a type of class-based View, which does not provide any method handlers such as .get() or .post(). Instead, it provides actions, such as .list(), .retrieve(), .create(), .update(), and .partial_update().

A ViewSet class is simply a type of class-based View, that does not provide any method handlers such as .get() or .post(), but instead provides actions. These actions are used for operations that are applied to a resource, like 'read', 'create', 'update' and 'delete'.

from rest_framework import viewsets

class UserViewSet(viewsets.ViewSet):
    A simple ViewSet for listing or retrieving users.
    def list(self, request):

    def retrieve(self, request, pk=None):

Why Use ViewSets?

ViewSets are designed to streamline the process of writing your views. They allow you to consolidate the logic for a set of related views in a single class, reducing redundancy and making your code easier to manage.

With ViewSets, you can avoid writing separate views for different HTTP methods and instead use a single class to handle all requests. This can make your code more concise and easier to read, as well as potentially reducing errors.

Routers and ViewSets

ViewSets, when used with Routers, can help you to quickly and easily generate a URL configuration for your API. The Router class in Django REST Framework provides simple, automatic URL routing to your ViewSet, creating a standard set of API endpoints.

from django.urls import path, include
from rest_framework.routers import DefaultRouter
from . import views

router = DefaultRouter()
router.register(r'users', views.UserViewSet)

urlpatterns = [
    path('', include(router.urls)),


A particularly useful subclass of ViewSet is the ModelViewSet. This inherits from a number of base classes that provide the complete set of default read and write operations.

from rest_framework import viewsets
from myapp.models import User
from myapp.serializers import UserSerializer

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

In conclusion, ViewSets in Django REST Framework are a powerful tool that can help you to write more efficient, manageable code. They provide a way to organize related views into a single class, and when used with Routers, they can simplify the process of creating your API's URL configuration.
