When you use a model with datetime with a timezone active and naive data
as input, it raise the follow error:
{{{
File "<basepath>/lib/python3.7/site-packages/pytz/tzinfo.py", line 234, in
localize
raise AmbiguousTimeError(dt)
pytz.exceptions.AmbiguousTimeError: 2020-10-25 02:00:01
}}}
The steps to reproduce are:
1. '''Use a model with datetime''': In this example, we are going to
create a user model that extends AbstractUser, but you could use any model
with a datetime field
{{{
class User(AbstractUser):
class Meta:
db_table = 'my_user'
created_at = models.DateTimeField(default=timezone.now)
updated_at = models.DateTimeField(auto_now=True)
last_password_change = models.DateTimeField(null=True)
}}}
2. '''Create an object with a string naive date''':
{{{
User.objects.create(
email = "[email protected]",
username = "user_25",
created_at = "2020-10-25 02:00:01"
)
}}}
* The timezone settings are:
TIME_ZONE = 'Europe/Rome'
USE_TZ = True
Database configuration has not timezone set
