Does Django Work With MySQL?
Django and MySQL work together seamlessly through Django's ORM layer, making this a production-ready combination widely used in enterprise applications.
Quick Facts
How Django Works With MySQL
Django's Object-Relational Mapping (ORM) provides a database-agnostic abstraction layer that supports MySQL out of the box through the `mysqlclient` or `PyMySQL` drivers. You define your data models in Python, and Django handles all SQL generation and database interactions automatically. This means developers write Pythonic code instead of raw SQL, gaining significant productivity benefits while maintaining full control over database design through migrations.
The integration is rock-solid for most use cases. Django's migrations system tracks schema changes in version control, making deployments predictable and reversible. The ORM supports complex queries including joins, aggregations, and subqueries, while still allowing raw SQL when needed. Connection pooling is handled transparently, and Django includes built-in support for transactions, cascading deletes, and foreign key relationships.
Architecturally, this pairing is ideal for monolithic applications, content management systems, and data-heavy web services. The combination handles millions of rows and high concurrency when properly configured. However, the ORM adds a small overhead compared to raw SQL—for extremely high-performance scenarios requiring hand-optimized queries, this might be a consideration, though rarely a blocker in practice.
Best Use Cases
Quick Setup
pip install django mysqlclient# settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'myapp_db',
'USER': 'django_user',
'PASSWORD': 'secure_password',
'HOST': 'localhost',
'PORT': '3306',
'OPTIONS': {
'charset': 'utf8mb4',
'init_command': "SET sql_mode='STRICT_TRANS_TABLES'",
}
}
}
# models.py
from django.db import models
class Product(models.Model):
name = models.CharField(max_length=200)
price = models.DecimalField(max_digits=10, decimal_places=2)
created_at = models.DateTimeField(auto_now_add=True)
class Meta:
db_table = 'products'
# Usage
products = Product.objects.filter(price__gt=100).select_related()
for product in products:
print(product.name)Known Issues & Gotchas
N+1 query problem when accessing related objects in loops
Fix: Use `select_related()` for foreign keys and `prefetch_related()` for many-to-many and reverse relations to batch queries
MySQL's default MyISAM engine doesn't support transactions; InnoDB may not be default in older versions
Fix: Explicitly set `ENGINE=InnoDB` in MySQL or configure it as the default storage engine before creating tables
String field max_length is enforced by Django but not always at database level in existing schemas
Fix: Use database constraints or ensure Django's validation is consistent with actual column definitions
MySQL's strict mode can reject Django ORM queries with incompatible data types or GROUP BY clauses
Fix: Enable MySQL strict mode in development to catch issues early, or configure Django's strict mode compatibility settings
Alternatives
- •Django with PostgreSQL—better JSON support, more advanced features, superior transaction isolation
- •FastAPI with SQLAlchemy and MySQL—more async-friendly, faster for high-concurrency APIs
- •Node.js (Express) with Sequelize and MySQL—JavaScript ecosystem, better for full-stack JavaScript teams
