What is Django Factory Boy and how do I use it?

Django Factory Boy is a library for creating test data in Django applications. It helps you generate complex objects easily.

Can you give me an example of how to create a simple factory?

Sure! You can create a factory for a model like this:

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)

How do I use this factory to create a test instance?

You can create an instance by calling the factory like this:

my_instance = MyModelFactory.create()

This will generate a new instance with random data.

Can I customize the data generated by the factory?

Yes, you can customize the data by passing parameters when you call the factory:

my_instance = MyModelFactory.create(name='John Doe', age=30)
