Building REST APIs with Django REST Framework

Django REST Framework Overview

Django REST Framework (DRF) is a powerful toolkit for building Web APIs in Django. It provides serialization, authentication, and browsable API features out of the box.

Key Features

1. Serialization that supports both ORM and non-ORM data sources
2. Authentication policies including OAuth1a and OAuth2
3. Customizable throttling and permissions
4. Browsable API for easy development and testing

Creating a Simple API

Define a serializer for your model:

from rest_framework import serializers
from .models import BlogPost

class BlogPostSerializer(serializers.ModelSerializer):
    class Meta:
        model = BlogPost
        fields = ['id', 'title', 'slug', 'body', 'published_date']

Then create a viewset:

from rest_framework import viewsets
from .models import BlogPost
from .serializers import BlogPostSerializer

class BlogPostViewSet(viewsets.ModelViewSet):
    queryset = BlogPost.objects.all()
    serializer_class = BlogPostSerializer
