Django REST framework is a robust and adaptable toolkit for creating RESTful Web APIs. Django is a Python Web platform that promotes quick development and clean, pragmatic design. Experienced developers have developed it to take care of most of the difficulties of Web development. It lets you focus on building your app instead of reinventing the wheel. It is open source and costs nothing. Django-REST framework is a Django online API system for creating sophisticated, highly customisable APIs and web-based applications.
It gracefully handles data Django-rest framework serializer and integrates with Django’s ORM. In comparison, Django accomplishes a lot of the heavy lifting by linking. Its models to the database, serializing them into JSON remains a significant hurdle. Rest Framework Django extends Django by allowing it to transform its models to a RESTful representation.
In this tutorial, experts will go over API development and how to implement it step by step. Rest API with Django has been used in every application or piece of software to link the front- and back-end sections; thus, it seems this would be valuable for any novice Django developer. If you master this, you can create a wide range of things.
What is Django REST Framework?
Django-REST Framework (DRF) is a popular, full-featured API framework for developing RESTful APIs using Django. It interacts with Django’s fundamental capabilities — models, views, and URLs. It makes creating a RESTful API straightforward. Below are the elements that make up DRF:
- Django QuerySets and model instances are converted to and from JSON. Although various other data rendering formats, including XML and YAML, use serializers.
- RESTful HTTP requests and answers are handled through views identical to conventional Django views and ViewSets. The statement validates incoming payloads with serializers. It contains the code to return the response. Routers Django-Rest Framework works with view sets to map the views to the exposed URLs.
Why Use the REST Framework of Django?
Many frameworks make it simple to create APIs for blog apps, but we’ll only use one: the REST framework (DRF). It is efficient in many ways and provides the following benefits:
-
Its Web-browsable API is a significant victory for your engineers in terms of convenience.
-
OAuth1 and OAuth2 packages appear in authentication policies.
-
Serializers Rest Framework, is compatible with both ORM and non-ORM data sources.
-
It is entirely customisable. If you don’t require the more advanced capabilities, utilize ordinary function-based views.
-
It contains a lot of documentation and a lot of community involvement.
-
Rest Framework Django serves and is trusted by well-known firms.
Rest Framework Apiview
Views in the Django-REST Framework (DRF) have their distinct flavor. It derives from the View class in Django. This three-part series offers a comprehensive look at all of the DRF view options, from the simple view, where you must do a lot of the work yourself, to the ModelViewSet, where you can create a view with very little code. The whole thing also demonstrates how viewpoints intersect since they are built on top of one another.

Before Installing The Rest Framework
Install the django admin startproject or framework initially. You must ensure that the following requirements are installed on your computer:
-
Python: The programming language that underpins the Django web development platform.
-
The Django framework in and of itself. For further information, see How to Install Django on Windows. It should either be deployed worldwide or in an online setting.
-
If you install Django in a virtual environment, ensure it is working.
-
You’ve already started working on a Django project.
The three steps listed above must be completed before you may install the DRF.
How To Develop A Django Project
The DR is a powerful and flexible toolkit for creating and configuring web APIs. Its adaptability makes it a popular choice for developing REST APIs. To begin, establish an online setting in a suitable folder using virtualenv, pinene, or any other virtual environment maker. Install Django and activate the virtual setup. Then, run the following command on your project console: start project django-admin ProjectName.
It isn’t necessary, but naming your Django project folder Config is an excellent practice. Happens because it only serves as a setup folder for your project. It includes the settings.py file, which we will use to register the REST framework as an installed app.
Also, a space is followed by a period next to the project folder name (Config). Again, this is optional, but it is done to make the Django project folder contain the manage.py file. That is the directory containing the virtual environment files or directories. That’s all there is to it; now let’s see how to install the DRF in the Django folder.
How To Install Django-REST Framework
There are two approaches that are advised for installing the REST framework in your Django project. The first is to use pip to install the rest framework, and the second is to clone the rest framework on github. Let us begin with the latter.
Method-1: Using Pip Install Django
Run the following command in your Django project terminal to Pip Install Django. The REST framework will be installed and available for registration in the settings.py file after installation.
Method-2: How To Clone The Django-Rest Framework On Github And Install It
Clone it from Github as an alternate way to install the REST framework. Launch your console and type the following command: git clone django-rest-framework. You must have git installed on your computer to use this technique.
Method-3: Add the Django-REST framework to Installed Apps
It is time to add the REST framework to the settings.py file in our project folder containing a list of installed apps.
Additional Installation Instructions For The Rest Framework of Django
It is crucial to examine the REST frameworks’ version installed in Django. You can use this information to determine whether the REST framework was installed properly. The simplest way is to use the pip show Rest Framework command. It displays more details about the REST framework, including its version.
After the command has finished, look at the second line. You may also execute pip freeze, which displays all the latest installed packages in your Django project. It includes a version number for the REST framework.
Once the command has finished, look at the third line. It’s also a good idea to check out the DRF version if you like the Django shell.
How To Uninstall REST Framework of Django
If you do not want the REST framework Django in your Django project, you can remove it using pip.
Final Verdict
DRF is the flexible toolkit for building sample to-do list applications. In the Rest Framework of Django, a variety of viewpoints are available. Concrete views, class-based views that extend the APIView class, and ModelViewSet are the ones that are most frequently used. The ease of customization and usability varies amongst them. For class-based views or function-based views, you may configure the policies (i.e., throttling, permissions) directly in the view or using decorators.
