Hi,
Here is my model:
class Flow(models.Model):
ref = models.CharField(max_length=32)
state = models.ForeignKey(State)
flow_type = models.ForeignKey(Type)
created = models.DateTimeField(db_index=True, auto_now_add=True)
modified = models.DateTimeField(db_index=True, auto_now=True)
version = models.IntegerField()
def __str__(self):
return str(self.id)
Here is my test.py file:
import warnings
warnings.filterwarnings(
'error', r"DateTimeField .* received a naive datetime",
RuntimeWarning, r'django\.db\.models\.fields')
In settings.py:
TIME_ZONE = 'Europe/London'
USE_TZ = True
Here is what happens when I run the test script:
>python manage.py test flow
Creating test database for alias 'default'...

RuntimeWarning: DateTimeField Flow.created received a naive datetime

What on earth is causing this "naive datetime" warning?
Thanks
