# Modern Django REST API Structure
from rest_framework import serializers, viewsets, permissions
from rest_framework.decorators import action
from rest_framework.response import Response
from django.db.models import Q, Prefetch

class DocumentSerializer(serializers.ModelSerializer):
    author = UserSerializer(read_only=True)
    tags = TagSerializer(many=True, read_only=True)
    
    class Meta:
        model = Document
        fields = ['id', 'title', 'content', 'author', 'tags', 'created_at']
        read_only_fields = ['author', 'created_at']

class DocumentViewSet(viewsets.ModelViewSet):
    serializer_class = DocumentSerializer
    permission_classes = [permissions.IsAuthenticated]
    filterset_fields = ['status', 'author']
    search_fields = ['title', 'content']
    ordering_fields = ['created_at', 'title']
    
    def get_queryset(self):
        return Document.objects.filter(
            Q(author=self.request.user) | Q(is_public=True)
        ).select_related('author').prefetch_related(
            Prefetch('tags', queryset=Tag.objects.all())
        )
    
    def perform_create(self, serializer):

Django Best Practices I Follow

• Fat models, thin views for business logic
• Custom user model from project start
• Settings splitting for environments
• 12-factor app configuration
• thorough testing with pytest-django
• Database optimization with select_related/prefetch_related

Frequently Asked Questions

How much does it cost to hire a Django developer?

Hiring a Django developer costs $80-160 per hour depending on experience. US-based senior developers charge $120-180/hour, European developers $70-140/hour. Project costs: basic web app $15,000-30,000, enterprise application $50,000-200,000+, complex multi-tenant SaaS $150,000-400,000+. Effective rates start at $50/hour with prepaid packages. See pricing for details with 6+ years Django production experience.

Where can I hire a Django developer?

Hire Django developers through: Upwork/Toptal (freelancers), Python-focused agencies, or direct contracts. Look for: Django REST Framework experience, database optimization skills, and testing practices. For AI-integrated Django apps, ensure they have LLM experience. I’m available for project or retainer work: cal.com/nazmul.

Django vs FastAPI vs Flask: which Python framework should I use in 2025?

Choose Django for: full-featured web apps, admin panels, rapid prototyping, content management. Choose FastAPI for: high-performance APIs, AI/ML backends, async workloads. Choose Flask for: microservices, maximum flexibility. Django has the largest ecosystem; FastAPI has the best performance. Many projects use Django + FastAPI together.

Is Django still relevant in 2025?

Yes. Django powers Instagram, Pinterest, Mozilla, Disqus, and thousands of production applications. Django 5.x adds async support, improved performance, and modern features. It’s the most battle-tested Python web framework with excellent documentation and ecosystem. I’ve built Django apps serving millions of users.

How long does it take to build a Django application?

Django development timeline: simple app 4-6 weeks, MVP 8-12 weeks, enterprise application 3-6 months. Django’s “batteries included” approach speeds initial development but complex customization takes time. Admin panel, auth, and ORM are built-in, you don’t rebuild these from scratch like with FastAPI/Flask.
