Bugs: models.DateField value has not been assigned correct date value when auto_now_add is set

[Racing Car]

class Vote(models.Model):

class Points(models.IntegerChoices):

Top = 3
Second = 2
Third = 1

points: models.IntegerField = models.IntegerField(choices=Points.choices, default=Points.Top)
date: models.DateField = models.DateField(auto_now_add=True)

from django.utils import timezone

timezone.now() # datetime.datetime(2024, 9, 18, 3, 7, 3, 608467, tzinfo=datetime.timezone.utc)
timezone.now().date()# datetime.date(2024, 9, 18)

import datetime
datetime.datetime.now() #datetime.datetime(2024, 9, 17, 23, 7, 14, 337114) My local pc timezone is UTC-4
datetime.date.today() #datetime.date(2024, 9, 17)

v = Vote(points=Vote.Points.Top)

v.save()
v.date # Expected value is datetime.date(2024, 9, 18) since I enabled USE_TZ=True in settings.py

# current value is datetime.date(2024, 9, 17)

"""
I figured it out myself and in pre_save function of models.DateField class, we should use timezone.now().date() instead of datetime.date.today()
