Django REST Framework Tutorial: Building REST APIs with Django

Introduction

Django REST Framework (DRF) is a powerful and flexible toolkit for building Web APIs in Django. It provides a set of tools and utilities that make it easy to build RESTful APIs with Django, including serializers, viewsets, authentication, permissions, pagination, and automatic API documentation.

This comprehensive tutorial will walk you through building a complete REST API using Django REST Framework. You'll learn how to create serializers, viewsets, handle authentication and permissions, implement filtering and pagination, and generate automatic API documentation. By the end of this tutorial, you'll have a solid understanding of building production-ready REST APIs with Django.

Prerequisites

Before starting, make sure you have:

Django knowledge: Basic understanding of Django (models, views, URLs)
Python 3.8+: Installed on your system
Django project: An existing Django project (or follow our Django Beginner Tutorial)
Basic API knowledge: Understanding of REST principles (GET, POST, PUT, DELETE)
Code editor: VS Code, PyCharm, or any editor you prefer
Terminal/Command Prompt: Access to run commands

If you haven't created a Django project yet, check out our Django Beginner Tutorial first.

Step 1: Installing Django REST Framework

First, let's install Django REST Framework in your Django project:

Install DRF:

bash
# Activate your virtual environment first
# On Windows: venv\Scripts\Activate.ps1
# On macOS/Linux: source venv/bin/activate

pip install djangorestframework

Add to INSTALLED_APPS:

Open your settings.py file and add rest_framework to INSTALLED_APPS:

python
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',  # Add Django REST Framework
    'blog',  # Your app
]

Configure REST Framework Settings (Optional):

Add REST framework settings to settings.py:

python
REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE': 10,
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    ],
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticatedOrReadOnly',
    ],
}

Verify Installation:

bash
python manage.py shell
>>> import rest_framework
>>> rest_framework.VERSION

You should see the DRF version number.

Step 2: Creating Models

Let's create models for our API. We'll use a blog example with Post and Comment models:

Create blog/models.py:

python
from django.db import models
from django.contrib.auth.models import User
from django.utils import timezone

class Post(models.Model):
    title = models.CharField(max_length=200)
    slug = models.SlugField(max_length=200, unique=True)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='posts')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    published_at = models.DateTimeField(null=True, blank=True)
    status = models.CharField(
        max_length=10,
        choices=[('draft', 'Draft'), ('published', 'Published')],
        default='draft'
    )
    
    class Meta:
        ordering = ['-created_at']
        
    def __str__(self):
        return self.title

class Comment(models.Model):
    post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='comments')
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    
    class Meta:
        ordering = ['-created_at']
        
    def __str__(self):
        return f'Comment by {self.author.username} on {self.post.title}'

Create and Apply Migrations:

bash
python manage.py makemigrations
python manage.py migrate

Step 3: Creating Serializers

Serializers convert model instances to JSON and vice versa. Create blog/serializers.py:

python
from rest_framework import serializers
from django.contrib.auth.models import User
from .models import Post, Comment

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'username', 'email', 'first_name', 'last_name']

class CommentSerializer(serializers.ModelSerializer):
    author = UserSerializer(read_only=True)
    
    class Meta:
        model = Comment
        fields = ['id', 'content', 'author', 'created_at', 'updated_at']
        read_only_fields = ['author', 'created_at', 'updated_at']

class PostSerializer(serializers.ModelSerializer):
    author = UserSerializer(read_only=True)
    comments = CommentSerializer(many=True, read_only=True)
    author_username = serializers.CharField(source='author.username', read_only=True)
    
    class Meta:
        model = Post
        fields = [
            'id', 'title', 'slug', 'content', 'author', 'author_username',
            'created_at', 'updated_at', 'published_at', 'status', 'comments'
        ]
        read_only_fields = ['author', 'created_at', 'updated_at']
    
    def create(self, validated_data):
        # Set author to current user
        validated_data['author'] = self.context['request'].user
        return super().create(validated_data)

class PostListSerializer(serializers.ModelSerializer):
    """Simplified serializer for list view"""
    author_username = serializers.CharField(source='author.username', read_only=True)
    comment_count = serializers.IntegerField(source='comments.count', read_only=True)
    
    class Meta:
        model = Post
        fields = [
            'id', 'title', 'slug', 'author_username',
            'created_at', 'published_at', 'status', 'comment_count'
        ]

Understanding Serializers:

ModelSerializer: Auto-generates fields from model
read_only=True: Field is read-only in API
many=True: For related objects (one-to-many)
source: Custom field source
create(): Custom creation logic
context: Access request in serializer

Step 4: Creating Viewsets

Viewsets combine the logic for multiple related views. Create blog/views.py:

python
from rest_framework import viewsets, status
from rest_framework.decorators import action
from rest_framework.response import Response
from rest_framework.permissions import IsAuthenticatedOrReadOnly, IsAuthenticated
from django.shortcuts import get_object_or_404
from .models import Post, Comment
from .serializers import PostSerializer, PostListSerializer, CommentSerializer

class PostViewSet(viewsets.ModelViewSet):
    """
    ViewSet for viewing and editing Post instances.
    Provides list, create, retrieve, update, and destroy actions.
    """
    queryset = Post.objects.all()
    permission_classes = [IsAuthenticatedOrReadOnly]
    
    def get_serializer_class(self):
        if self.action == 'list':
            return PostListSerializer
        return PostSerializer
    
    def get_queryset(self):
        queryset = Post.objects.all()
        status_param = self.request.query_params.get('status', None)
        author_param = self.request.query_params.get('author', None)
        
        if status_param:
            queryset = queryset.filter(status=status_param)
        if author_param:
            queryset = queryset.filter(author__username=author_param)
        
        return queryset
    
    @action(detail=True, methods=['post'], permission_classes=[IsAuthenticated])
    def publish(self, request, pk=None):
        """Custom action to publish a post"""
        post = self.get_object()
        if post.author != request.user:
            return Response(
                {'error': 'You can only publish your own posts.'},
                status=status.HTTP_403_FORBIDDEN
            )
        post.status = 'published'
        post.published_at = timezone.now()
        post.save()
        return Response({'status': 'post published'})
    
    @action(detail=True, methods=['get', 'post'])
    def comments(self, request, pk=None):
        """Custom action to get or create comments for a post"""
        post = self.get_object()
        
        if request.method == 'GET':
            comments = post.comments.all()
            serializer = CommentSerializer(comments, many=True)
            return Response(serializer.data)
        
        elif request.method == 'POST':
            serializer = CommentSerializer(data=request.data)
            if serializer.is_valid():
                serializer.save(post=post, author=request.user)
                return Response(serializer.data, status=status.HTTP_201_CREATED)
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

class CommentViewSet(viewsets.ModelViewSet):
    """
    ViewSet for viewing and editing Comment instances.
    """
    queryset = Comment.objects.all()
    serializer_class = CommentSerializer
    permission_classes = [IsAuthenticatedOrReadOnly]
    
    def perform_create(self, serializer):
        serializer.save(author=self.request.user)

Understanding ViewSets:

ModelViewSet: Provides CRUD operations
get_serializer_class(): Different serializers for different actions
get_queryset(): Custom queryset filtering
@action: Custom actions beyond CRUD
permission_classes: Control access
perform_create(): Custom creation logic

Step 5: Setting Up URLs with Routers

DRF routers automatically generate URL patterns for viewsets. Create blog/urls.py:

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

# Create router and register viewsets
router = DefaultRouter()
router.register(r'posts', PostViewSet, basename='post')
router.register(r'comments', CommentViewSet, basename='comment')

app_name = 'blog'

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

Update main urls.py:

python
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/', include('blog.urls')),  # API endpoints
    path('api-auth/', include('rest_framework.urls')),  # Login/logout for browsable API
]

Available Endpoints:

GET /api/posts/ - List all posts
POST /api/posts/ - Create a new post
GET /api/posts/{id}/ - Retrieve a post
PUT /api/posts/{id}/ - Update a post
PATCH /api/posts/{id}/ - Partially update a post
DELETE /api/posts/{id}/ - Delete a post
POST /api/posts/{id}/publish/ - Custom action: publish post
GET /api/posts/{id}/comments/ - Get comments for a post
POST /api/posts/{id}/comments/ - Create comment for a post

Step 6: Authentication and Permissions

DRF provides multiple authentication methods. Let's set up token authentication:

Install Token Authentication:

bash
pip install djangorestframework-simplejwt

Add to INSTALLED_APPS:

python
INSTALLED_APPS = [
    # ... other apps
    'rest_framework',
    'rest_framework_simplejwt',  # JWT authentication
]

Update REST Framework Settings:

python
from datetime import timedelta

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework_simplejwt.authentication.JWTAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    ],
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticatedOrReadOnly',
    ],
}

SIMPLE_JWT = {
    'ACCESS_TOKEN_LIFETIME': timedelta(minutes=60),
    'REFRESH_TOKEN_LIFETIME': timedelta(days=1),
}

Add JWT URLs:

python
from django.urls import path, include
from rest_framework_simplejwt.views import TokenObtainPairView, TokenRefreshView

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/', include('blog.urls')),
    path('api/token/', TokenObtainPairView.as_view(), name='token_obtain_pair'),
    path('api/token/refresh/', TokenRefreshView.as_view(), name='token_refresh'),
]

Custom Permissions:

Create blog/permissions.py:

python
from rest_framework import permissions

class IsAuthorOrReadOnly(permissions.BasePermission):
    """
    Custom permission to only allow authors to edit their own posts.
    """
    def has_object_permission(self, request, view, obj):
        # Read permissions for any request
        if request.method in permissions.SAFE_METHODS:
            return True
        
        # Write permissions only to the author
        return obj.author == request.user

Use Custom Permission:

python
from .permissions import IsAuthorOrReadOnly

class PostViewSet(viewsets.ModelViewSet):
    permission_classes = [IsAuthenticatedOrReadOnly, IsAuthorOrReadOnly]
    # ... rest of the code

Step 7: Filtering and Search

Add filtering and search capabilities using django-filter:

Install django-filter:

bash
pip install django-filter

Add to INSTALLED_APPS:

python
INSTALLED_APPS = [
    # ... other apps
    'django_filters',
]

Update REST Framework Settings:

python
REST_FRAMEWORK = {
    # ... other settings
    'DEFAULT_FILTER_BACKENDS': [
        'django_filters.rest_framework.DjangoFilterBackend',
        'rest_framework.filters.SearchFilter',
        'rest_framework.filters.OrderingFilter',
    ],
}

Add Filtering to ViewSet:

python
from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import filters

class PostViewSet(viewsets.ModelViewSet):
    queryset = Post.objects.all()
    serializer_class = PostSerializer
    filter_backends = [DjangoFilterBackend, filters.SearchFilter, filters.OrderingFilter]
    filterset_fields = ['status', 'author']
    search_fields = ['title', 'content']
    ordering_fields = ['created_at', 'published_at', 'title']
    ordering = ['-created_at']

Usage Examples:

GET /api/posts/?status=published - Filter by status
GET /api/posts/?author=username - Filter by author
GET /api/posts/?search=django - Search in title and content
GET /api/posts/?ordering=-created_at - Order by creation date
GET /api/posts/?status=published&search=django&ordering=-published_at - Combined filters

Step 8: Pagination

DRF provides built-in pagination classes. Configure pagination in settings.py:

python
REST_FRAMEWORK = {
    # ... other settings
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE': 10,
}

Custom Pagination Class:

Create blog/pagination.py:

python
from rest_framework.pagination import PageNumberPagination

class PostPagination(PageNumberPagination):
    page_size = 10
    page_size_query_param = 'page_size'
    max_page_size = 100

Use Custom Pagination:

python
from .pagination import PostPagination

class PostViewSet(viewsets.ModelViewSet):
    pagination_class = PostPagination
    # ... rest of the code

Pagination Response Format:

json
{
    "count": 50,
    "next": "http://example.com/api/posts/?page=3",
    "previous": "http://example.com/api/posts/?page=1",
    "results": [
        // ... post objects
    ]
}

Step 9: API Documentation with Swagger/OpenAPI

Generate automatic API documentation using drf-yasg or drf-spectacular:

Install drf-spectacular:

bash
pip install drf-spectacular

Add to INSTALLED_APPS:

python
INSTALLED_APPS = [
    # ... other apps
    'drf_spectacular',
]

Update REST Framework Settings:

python
REST_FRAMEWORK = {
    # ... other settings
    'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema',
}

SPECTACULAR_SETTINGS = {
    'TITLE': 'Blog API',
    'DESCRIPTION': 'A comprehensive blog API built with Django REST Framework',
    'VERSION': '1.0.0',
    'SERVE_INCLUDE_SCHEMA': False,
}

Add Documentation URLs:

python
from drf_spectacular.views import SpectacularAPIView, SpectacularSwaggerView

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/', include('blog.urls')),
    path('api/schema/', SpectacularAPIView.as_view(), name='schema'),
    path('api/docs/', SpectacularSwaggerView.as_view(url_name='schema'), name='swagger-ui'),
]

Access Documentation:

Swagger UI: http://127.0.0.1:8000/api/docs/
ReDoc: http://127.0.0.1:8000/api/schema/redoc/
OpenAPI Schema: http://127.0.0.1:8000/api/schema/

Step 10: Testing the API

DRF provides a test client for testing APIs. Create blog/tests.py:

python
from django.contrib.auth.models import User
from django.urls import reverse
from rest_framework.test import APITestCase, APIClient
from rest_framework import status
from .models import Post

class PostAPITestCase(APITestCase):
    def setUp(self):
        self.client = APIClient()
        self.user = User.objects.create_user(
            username='testuser',
            password='testpass123'
        )
        self.post = Post.objects.create(
            title='Test Post',
            slug='test-post',
            content='Test content',
            author=self.user,
            status='published'
        )
    
    def test_list_posts(self):
        """Test listing all posts"""
        url = reverse('post-list')
        response = self.client.get(url)
        self.assertEqual(response.status_code, status.HTTP_200_OK)
        self.assertEqual(len(response.data['results']), 1)
    
    def test_create_post(self):
        """Test creating a new post"""
        self.client.force_authenticate(user=self.user)
        url = reverse('post-list')
        data = {
            'title': 'New Post',
            'slug': 'new-post',
            'content': 'New content'
        }
        response = self.client.post(url, data, format='json')
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)
        self.assertEqual(Post.objects.count(), 2)
    
    def test_retrieve_post(self):
        """Test retrieving a single post"""
        url = reverse('post-detail', kwargs={'pk': self.post.pk})
        response = self.client.get(url)
        self.assertEqual(response.status_code, status.HTTP_200_OK)
        self.assertEqual(response.data['title'], 'Test Post')
    
    def test_update_post(self):
        """Test updating a post"""
        self.client.force_authenticate(user=self.user)
        url = reverse('post-detail', kwargs={'pk': self.post.pk})
        data = {'title': 'Updated Post'}
        response = self.client.patch(url, data, format='json')
        self.assertEqual(response.status_code, status.HTTP_200_OK)
        self.post.refresh_from_db()
        self.assertEqual(self.post.title, 'Updated Post')
    
    def test_delete_post(self):
        """Test deleting a post"""
        self.client.force_authenticate(user=self.user)
        url = reverse('post-detail', kwargs={'pk': self.post.pk})
        response = self.client.delete(url)
        self.assertEqual(response.status_code, status.HTTP_204_NO_CONTENT)
        self.assertEqual(Post.objects.count(), 0)
    
    def test_publish_action(self):
        """Test custom publish action"""
        self.client.force_authenticate(user=self.user)
        url = reverse('post-publish', kwargs={'pk': self.post.pk})
        response = self.client.post(url)
        self.assertEqual(response.status_code, status.HTTP_200_OK)
        self.post.refresh_from_db()
        self.assertEqual(self.post.status, 'published')

Run Tests:

bash
python manage.py test blog.tests

Step 11: API Versioning

Implement API versioning for backward compatibility:

Update REST Framework Settings:

python
REST_FRAMEWORK = {
    # ... other settings
    'DEFAULT_VERSIONING_CLASS': 'rest_framework.versioning.URLPathVersioning',
    'DEFAULT_VERSION': 'v1',
    'ALLOWED_VERSIONS': ['v1', 'v2'],
    'VERSION_PARAM': 'version',
}

Update URLs:

python
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/v1/', include('blog.urls')),  # Version 1
    path('api/v2/', include('blog.v2.urls')),  # Version 2
]

Access Versioned API:

GET /api/v1/posts/ - Version 1
GET /api/v2/posts/ - Version 2

Step 12: Throttling (Rate Limiting)

Implement rate limiting to prevent API abuse:

Update REST Framework Settings:

python
REST_FRAMEWORK = {
    # ... other settings
    'DEFAULT_THROTTLE_CLASSES': [
        'rest_framework.throttling.AnonRateThrottle',
        'rest_framework.throttling.UserRateThrottle'
    ],
    'DEFAULT_THROTTLE_RATES': {
        'anon': '100/hour',
        'user': '1000/hour'
    }
}

Custom Throttling:

Create blog/throttling.py:

python
from rest_framework.throttling import UserRateThrottle

class PostCreateThrottle(UserRateThrottle):
    scope = 'post_create'

Update Settings:

python
'DEFAULT_THROTTLE_RATES': {
    'anon': '100/hour',
    'user': '1000/hour',
    'post_create': '10/hour',  # Custom throttle
}

Use Custom Throttle:

python
from .throttling import PostCreateThrottle

class PostViewSet(viewsets.ModelViewSet):
    throttle_classes = [PostCreateThrottle]
    # ... rest of the code

Step 13: Error Handling

Customize error handling for better API responses:

Create Custom Exception Handler:

Create blog/exceptions.py:

python
from rest_framework.views import exception_handler
from rest_framework.response import Response
from rest_framework import status

def custom_exception_handler(exc, context):
    # Call REST framework's default exception handler first
    response = exception_handler(exc, context)
    
    # Customize the response
    if response is not None:
        custom_response_data = {
            'error': {
                'status_code': response.status_code,
                'message': 'An error occurred',
                'details': response.data
            }
        }
        response.data = custom_response_data
    
    return response

Update Settings:

python
REST_FRAMEWORK = {
    # ... other settings
    'EXCEPTION_HANDLER': 'blog.exceptions.custom_exception_handler',
}

Step 14: Testing API with HTTPie or cURL

Test your API using HTTPie or cURL:

Install HTTPie:

bash
pip install httpie

Test API Endpoints:

bash
# Get access token
http POST http://127.0.0.1:8000/api/token/ username=testuser password=testpass123

# List posts
http GET http://127.0.0.1:8000/api/posts/

# Create post (with authentication)
http POST http://127.0.0.1:8000/api/posts/ \
    "Authorization: Bearer YOUR_ACCESS_TOKEN" \
    title="New Post" \
    slug="new-post" \
    content="Post content"

# Update post
http PATCH http://127.0.0.1:8000/api/posts/1/ \
    "Authorization: Bearer YOUR_ACCESS_TOKEN" \
    title="Updated Post"

# Delete post
http DELETE http://127.0.0.1:8000/api/posts/1/ \
    "Authorization: Bearer YOUR_ACCESS_TOKEN"

# Custom action
http POST http://127.0.0.1:8000/api/posts/1/publish/ \
    "Authorization: Bearer YOUR_ACCESS_TOKEN"

Using cURL:

bash
# Get access token
curl -X POST http://127.0.0.1:8000/api/token/ \
    -H "Content-Type: application/json" \
    -d '{"username":"testuser","password":"testpass123"}'

# List posts
curl http://127.0.0.1:8000/api/posts/

# Create post
curl -X POST http://127.0.0.1:8000/api/posts/ \
    -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
    -H "Content-Type: application/json" \
    -d '{"title":"New Post","slug":"new-post","content":"Post content"}'

Best Practices

Follow these best practices when building REST APIs with DRF:

1. Use ViewSets for CRUD Operations:

ViewSets reduce code duplication
Automatic URL routing
Consistent API structure

2. Separate Serializers for Different Actions:

Use different serializers for list vs detail views
Optimize data transfer
Improve performance

3. Implement Proper Authentication:

Use JWT for stateless authentication
Implement token refresh
Secure token storage

4. Set Appropriate Permissions:

Use custom permissions when needed
Follow principle of least privilege
Document permission requirements

5. Implement Filtering and Search:

Use django-filter for complex filtering
Implement search functionality
Add ordering capabilities

6. Use Pagination:

Always paginate large datasets
Allow configurable page size
Provide pagination metadata

7. Version Your API:

Plan for API versioning from the start
Maintain backward compatibility
Document version changes

8. Handle Errors Gracefully:

Custom exception handlers
Meaningful error messages
Proper HTTP status codes

9. Document Your API:

Use automatic documentation tools
Document all endpoints
Provide examples

10. Test Thoroughly:

Write unit tests
Test authentication and permissions
Test edge cases
