I am trying to use factory boy to generate fake entries but I'm stepping on an issue related with the boolean field.
Follows the Model and ModelFactory:
# models.py
class Record(models.Model):
date_creation = models.DateTimeField()
rec_type = models.CharField(max_length=1, choices=RECORD_TYPES)
direction = models.BooleanField()
# factories.py
class RecordFactory(DjangoModelFactory):
class Meta:
model = Record
date_creation = factory.Faker('date_time')
rec_type = factory.Faker('random_choices', elements=[x[1] for x in Record.RECORD_TYPES])
direction = factory.Faker('pybool')
How do I fix this issue? Seems to be related with the boolean field.
/usr/local/lib/python3.7/site-packages/django/db/models/fields/__init__.py:1427: RuntimeWarning: DateTimeField Record.date_creation received a naive datetime (1
977-11-24 14:21:26) while time zone support is active.

The above exception was the direct cause of the following exception:

The major issue was that I was using the wrong Faker. This one did what I expected:
# factories.py
...
rec_type = factory.Faker('random_element', elements=[x[0] for x in Record.RECORD_TYPES])
...
