What is Django Rest Framework (DRF) and why use it?

Django Rest Framework (DRF) is a powerful toolkit for building Web APIs in Django. It simplifies the process of creating RESTful APIs by providing features like serialization, authentication, and viewsets. Here's how to get started:

1. Install DRF using

   pip install djangorestframework

   .
2. Add 'rest_framework' to your INSTALLED_APPS in settings.py.
3. Create serializers for your models to convert querysets into JSON.

For example, if you have a Post model, your serializer might look like this:

from rest_framework import serializers
class PostSerializer(serializers.ModelSerializer):
    class Meta:
        model = Post
        fields = '__all__'

DRF allows you to quickly expose your Django models as APIs.
