Django is a free and open-source Python Web Framework that leverages the Model–Template–Views architectural paradigm. The Django Software Foundation, a non-profit organization based in the United States, is responsible for its maintenance. Django allows you to quickly and easily create a high-quality Web application. It is appropriate for both frontend and backend development.

Django adheres to strong design principles throughout its code and makes it simple to adopt top web-development techniques. Some of the well-known platforms that use Django are Instagram, Disqus, Washington Times, Bitbucket, and Mozilla. This Framework acts as a connector between the Data Model and the Database Engine, and it supports a wide range of databases. Django’s philosophy is to do everything possible to make hyper-fast development possible.

Key Features of Django

Django is a high-level Python Web Framework for building secure and reliable websites quickly. Let’s look at some of the features of Django, that make it a popular choice among Python Developers:

  • Secure: Django has been designed to automatically “Do the Right Things” in order to protect the website. Django avoids common pitfalls like storing session information in cookies, which is vulnerable. SQL injection, cross-site scripting, cross-site request forgery, and clickjacking are all vulnerabilities that Django protects against by default.
  • Scalable: Django employs a “Shared-Nothing” architecture i.e each part of the architecture is independent of the others.  Since the various components are clearly separated, it can scale to accommodate additional demand by adding hardware at any level.
  • Maintainable: Django code is constructed with design principles and patterns in mind, resulting in code that is easy to maintain and reuse. It employs the “Don’t Repeat Yourself” (DRY) concept to eliminate needless repetition and hence reduce the amount of code. 
  • Versatile: From content management systems and wikis to social networks and news sites, Django can be used to create practically any kind of website. It can integrate with any client-side framework and serve information in nearly any format (including HTML, RSS feeds, JSON, XML, etc).
  • Portable: Django is written in Python, a programming language that runs on a variety of platforms. That means you’re not locked into a single server platform and can run your apps on a variety of operating systems such as Linux, Windows, and Mac OS X. Django is also well-supported by a large number of web hosting companies, who often provide dedicated infrastructure and documentation for hosting Django sites.

Introduction to REST APIs

REST APIs is an acronym for Representational State Transfer Application Programming Interface. A REST API is a frontend for a data source that lets users create, retrieve, update, and remove data items. For Developer teams, an API is often a gateway to the rest of the world. In a typical 3-tier application, it stands between the User Interface (which allows end-users to access and alter data), and the Database (which stores the data).

A REST API is a set of protocols that govern how different apps communicate via HTTP. There are 4 basic methods, which are also referred to as CRUD operations: 

  • POST: Create
  • GET: Read
  • PUT: Update
  • DELETE: Delete

These CRUD methods are used to access and utilize data in an HTTP request. As these components are loosely coupled, information flows quickly and efficiently. It can also be used for a wider range of purposes and is easier to design because the data formats aren’t pre-defined. As a result, REST APIs have become the industry standard for web-based APIs and are a popular choice among Web Developers.

Introduction to Django REST Framework

Django REST Framework (DRF) is a Python application that allows you to quickly create RESTful APIs using Django models. It has various capabilities to assist Developers in creating capable web applications, such as data views and Model-View-Controller (MVC) patterns, forms, templates, database management, caching, security, and so on, in addition to HTTP and application middleware. Django can be installed using Python’s pip package management with only a single command.

The following are some reasons why you might want to use the Django REST framework:

  • For your Developers, the Web browsable API is a major victory in terms of usability.
  • Authentication policies, including OAuth1a and OAuth2 packages.
  • ORM and non-ORM data sources are supported through Serialization.
  • Customizable with extensive documentation and community support.
  • Mozilla, Red Hat, Heroku, and Eventbrite are just a few of the well-known enterprises that use and trust it.

Steps to Create a REST API using Django REST Framework

The Django REST Framework is a wrapper for the standard Django Framework that is used to develop multiple APIs.  Let’s dive deep and understand how to build a REST API using Django REST Framework.

Step 1: Install Django REST Framework

The first step includes the installation of the Django REST Framework. You can install Django REST Framework by any of the following methods mentioned below.

1) Using pip command

Enter the following command in your Python IDE command-line interface:

pip install djangorestframework
pip install markdown       # Markdown support for the browsable API.
pip install django-filter  # Filtering support

2) By cloning project from GitHub

Enter the following command in your Python IDE command-line interface:

git clone

The next step is to add “rest_framework” to your “INSTALLED_APPS” setting as shown below.


If you’re intending to use the browsable API you’ll probably also want to add the REST framework’s login and logout views. To your root file, add the following code. It’s worth noting that the URL route can be anything you desire.

urlpatterns = [
    path('api-auth/', include('rest_framework.urls'))

Step 2: Create REST API

In this step, you will build a simple model-backed API using Django REST Framework. You will develop a simple read-write API to obtain information about your project’s users. Follow the steps below:

  • Open your module and add the following commands to create a REST_FRAMEWORK dictionary. It will store all the global settings for a REST framework API in a single configuration dictionary.
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
  • Next in your project’s root module, enter the following code to create your API.
from django.urls import path, include
from django.contrib.auth.models import User
from rest_framework import routers, serializers, viewsets

# Serializers define the API representation.
class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ['url', 'username', 'email', 'is_staff']

# ViewSets define the view behavior.
class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

# Routers provide an easy way of automatically determine the URL configuration.
router = routers.DefaultRouter()
router.register(r'users', UserViewSet)

# Wire up your API using automatic URL routing.
# Additionally, you can include login URLs for the browsable API.
urlpatterns = [
    path('', include(router.urls)),
    path('api-auth/', include('rest_framework.urls', namespace='rest_framework'))

In the above code, there are certain terms you need to be aware of. These have been discussed below in brief.

  • Serialization: Serializers enable complex data, such as querysets and model instances, to be transformed to native Python datatypes, which can subsequently be translated into JSON, XML, and other content types with ease. After validating the incoming data, serializers also enable deserialization, which allows parsed data to be transformed back into complex types. data to be converted back into complex types, after first validating the incoming data.
  • ViewSet: The REST framework contains an abstraction for dealing with ViewSets, which allows the Developer to focus on modeling the API’s state and interactions while the URL building is handled automatically based on industry standards. ViewSet classes are nearly identical to View classes, with the exception that they include actions like retrieve and update rather than method handlers like get and put. When a ViewSet class is instantiated into a set of views, it is only bound to a set of method handlers at the last minute, often by utilizing a Router class, which handles the complexity of establishing the URL conf for you.
  • URLs of API: In the above code you are using ViewSets instead of views, hence you can automatically generate the URL conf for your API, by simply registering the ViewSets with a router class. If you need more control over the API URLs, just use standard class-based views and explicitly write the URL conf. You’ve also supplied default login and logout views for use with the browsable API in this example, which is optional.

Step 3: Test REST API

After entering and saving your code, you can now test your REST API created using Django REST Framework. To test, open the API in your browser at, and view your new ‘users’ API. You can also add, create, and delete users from the system by using the login control in the top right corner.

Felicitations!! You have successfully created and tested your REST API created using Django REST Framework.
