model-mommy

What it is and what it does

Model Mommy is a Django testing utility that automatically generates model instances populated with random data, eliminating the need to manually specify every field when creating test fixtures. It introspects Django models and fills in required fields intelligently, making it faster to write test setup code.

However, the package has been abandoned since October 2019 and is no longer maintained. The creators explicitly recommend migrating to Model Bakery, a renamed successor that continues development. While Model Mommy remains functional for legacy projects, new projects should use Model Bakery instead to ensure ongoing support and compatibility with current Django versions.

Use it for:

• Quickly populate test databases with realistic Django model instances without writing repetitive fixture code.
• Generate related model objects automatically during unit tests to reduce boilerplate in test setup methods.
• Create temporary test data with random values to verify model behavior across different field combinations.
