I'm using Django 2, Python 3.7 and factory-boy. Trying to create a factory for the django-address' AddressField -- https://pypi.org/project/django-address/ , which I guess is a non-traditional model, in that it doesn't inherit from models.Model. I created this factory, using objects = models.Manager() ...
class AddressFactory(factory.DjangoModelFactory):
"""
Define Address Factory
"""
objects = models.Manager()
class Meta:
model = AddressField
street_number = "123"
route = "Rd"
raw = "123 Fake Rd"
formatted = "123 Fake Rd."
latitude = 87.1234
longitude = -100.12342
locality = factory.SubFactory(LocalityFactory)
class CoopFactory(factory.DjangoModelFactory):
"""
Define Coop Factory
"""
class Meta:
model = Coop
name = "test model"
address = factory.SubFactory(AddressFactory)
enabled = True
phone = "312-999-1234"
email = "[email protected]"
web_site = "http://www.hello.com"
@factory.post_generation
def types(self, create, extracted, **kwargs):
if not create:
# Simple build, do nothing.
return
if extracted:
# A list of types were passed in, use them
for type in extracted:
self.types.add(type)
else:
type = factory.SubFactory(CoopTypeFactory)
self.types.all().set( (type) )
Then I have this test ...
@pytest.mark.django_db
def test_address_create(self):
""" Test address model """ # create customer model instance
address = AddressFactory()
assert address is not None
but running the test results in the below error ...
davea$ python manage.py test --settings=maps.test_settings

What do I need to do to build a factory for this type of object?
Edit: This is my Coop model in all its glory ...
class Coop(models.Model):
objects = CoopManager()
name = models.CharField(max_length=250, null=False)
types = models.ManyToManyField(CoopType)
address = AddressField(on_delete=models.CASCADE)
enabled = models.BooleanField(default=True, null=False)
phone = PhoneNumberField(null=True)
email = models.EmailField(null=True)
web_site = models.TextField()
The base Coop model should be similar to:
from address.models import AddressField
from django.db import models
class Coop(models.Model):
name = models.CharField(max_length=255)
address = AddressField()
To configure the factories in your tests, you have to create a factory for each model from django-address
class CountryFactory(factory.DjangoModelFactory):
class Meta:
model = 'address.Country'
name = 'Test Country'
code = '123'
class StateFactory(factory.DjangoModelFactory):
class Meta:
model = 'address.State'
name = 'Test State'
code = '456'
country = factory.SubFactory(CountryFactory)
class LocalityFactory(factory.DjangoModelFactory):
class Meta:
model = 'address.Locality'
name = 'Test Locality'
postal_code = '123'
state = factory.SubFactory(StateFactory)
class AddressFactory(factory.DjangoModelFactory):
class Meta:
model = 'address.Address'
street_number = "123"
route = "Rd"
raw = "123 Fake Rd"
formatted = "123 Fake Rd."
latitude = 87.1234
longitude = -100.12342
locality = factory.SubFactory(LocalityFactory)
class CoopFactory(factory.DjangoModelFactory):
class Meta:
model = Coop
name = 'new Coop'
address = factory.SubFactory(AddressFactory)
And the test will be:
class FactoryTest(TestCase):
def test_example(self):
coop_from_factory = CoopFactory()
self.assertIsNotNone(coop_from_factory)
coop = Coop.objects.create(name='test', address=coop_from_factory.address)
self.assertIsNotNone(coop)
