How can I use Factory Boy for testing in Django?

Factory Boy is a powerful library for creating test data in Django. You can define factories for your models and easily generate instances for testing.

Can you show me a simple example of a factory for a Django model?

Sure! Here's a basic example:

import factory
from myapp.models import MyModel

class MyModelFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = MyModel

    name = factory.Faker('name')
    age = factory.Faker('random_int', min=18, max=90)

This factory will create instances of MyModel with random names and ages.

How do I use this factory in my tests?

You can use the factory in your test cases like this:

from myapp.factories import MyModelFactory

class MyModelTestCase(TestCase):
    def test_my_model_creation(self):
        instance = MyModelFactory.create()
        self.assertIsNotNone(instance.id)
