Factory Boy random choice for a field with field option "choices"

You'll not need a FuzzyAttribute.

You can either restrict the values possible and only give the int value of each product type to FuzzyChoice by doing something like this:

PRODUCT_IDS = [x[0] for x in IceCreamProduct.PRODUCT_TYPES]
class IceCreamProductFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = IceCreamProduct

    type = factory.fuzzy.FuzzyChoice(PRODUCT_IDS)

It should do the work.

Please be aware that fuzzy module has been deprecated recently, see ( https://factoryboy.readthedocs.org/en/latest/fuzzy.html), you may want to use a LazyFunction instead.

You can do as easy as this

class IceCreamProductFactory(factory.django.DjangoModelFactory):
    icecream_flavour = factory.Faker(
        'random_element', elements=[x[0] for x in IceCreamProduct.PRODUCT_TYPES]
    )

    class Meta:
        model = IceCreamProduct

PS. Don't use type as attribute, it is a bad practice to use a built-in function name as an attribute
