Я пытаюсь использовать модуль factory-bot Django для создания фабрик для моих моделей. Я также использую pytest. Я создал эти фабрики ...
import factory
from maps.models import CoopType, Coop
from address.models import AddressField
from phonenumber_field.modelfields import PhoneNumberField
from address.models import State, Country, Locality
class CountryFactory(factory.DjangoModelFactory):
"""
Define Country Factory
"""
class Meta:
model = Country
name = "Narnia"
code = "NN"
class StateFactory(factory.DjangoModelFactory):
"""
Define State Factory
"""
class Meta:
model = State
name = "Narnia"
code = "NN"
country = CountryFactory()
class LocalityFactory(factory.DjangoModelFactory):
"""
Define Locality Factory
"""
class Meta:
model = Locality
name = "Narnia"
postal_code = "60605"
state = StateFactory()
class AddressFactory(factory.DjangoModelFactory):
"""
Define Address Factory
"""
class Meta:
model = Address
street_number = "123"
route = "Rd"
raw = "123 Fake Rd"
formatted = "123 Fake Rd."
latitude = 87.1234
longitude = -100.12342
locality = LocalityFactory()
class CoopTypeFactory(factory.DjangoModelFactory):
"""
Define Coop Type Factory
"""
class Meta:
model = CoopType
Пока у меня есть очень простой тестовый файл. У него только один тест ...
import pytest
from django.test import TestCase
from .factories import CoopTypeFactory, CoopFactory
class ModelTests(TestCase):
@classmethod
def setUpTestData(cls):
print("setUpTestData: Run once to set up non-modified data for all class methods.")
#management.call_command('loaddata', 'test_data.yaml', verbosity=0)
pass
def setUp(self):
print("setUp: Run once for every test method to setup clean data.")
#management.call_command('flush', verbosity=0, interactive=False)
pass
@pytest.mark.django_db
def test_coop_type_create(self):
""" Test customer model """ # create customer model instance
coop_type = CoopTypeFactory(name="Test Coop Type Name")
assert coop_type.name == "Test Coop Type Name"
Но когда я запускаю свой тест, он умирает, жалуясь на дубликат ключа для фабрики, которую я даже не создаю.
davea$ python manage.py test --settings=maps.test_settings

Что я делаю не так? Почему Django пытается создать фабрику для чего-то, для чего я не создаю фабрику?
