I'm seeing duplicate values being generated when using randint and factory_boy. My test fails when checking for the asset for each object. The barcode is also the same between the two when calling create() on the factory.
Do I need to provide a different seed before each object creation?

seed/factories.py
import factory
from A1.models import *
from random import randint, random
faker = Factory.create()
class AssetFactory(factory.DjangoModelFactory):
class Meta:
model = Asset
asset = "ABC" + str(randint(0000, 9999))
barcode = "AA" + randint(111111, 999999)
user = factory.lazy_attribute(lambda x: faker.name())
tests.py
def test_randomCreation(self):
new_asset = AssetFactory.create()
new_asset2 = AssetFactory.create()
self.assertNotEqual(new_asset.asset, new_asset2.asset) #FAILS
A1/models.py
class Asset(models.Model):
asset = models.CharField(max_length=255, verbose_name="Asset")
barcode = models.CharField(max_length=255)
user = models.CharField(max_length=255)
May someone point me in the right direction? Thanks in advance!!
The way the Python language is designed, your code cannot work.
It is strictly equivalent to the following:
_RANDOM_ASSET = "ABC" + str(randint(0000, 9999))
_RANDOM_BARCODE = "AA" + str(randint(111111, 999999))
class AssetFactory(factory.django.DjangoModelFactory):
class Meta:
model = models.Asset
asset = _RANDOM_ASSET
barcode = _RANDOM_BARCODE
user = factory.LazyAttribute(lambda x: faker.name())
You've fixed a random value for asset
and barcode
, so every object generated through that factory will have the exact same value.
The proper way would be to use the various built-in declarations:
class AssetFactory(factory.django.DjangoModelFactory):
class Meta:
model = models.Asset
asset = factory.fuzzy.FuzzyText(length=4, prefix='ABC', chars=string.digits)
barcode = factory.fuzzy.FuzzyText(length=6, prefix='AA', chars=string.digits)
user = factory.Faker('name')
