New to Django and python, been following a tutorial and playing around with creating a user to user messaging functionality. So far all works great except that when I visit the messages page I always get an alert like: {'user': <User: test2>, 'last': datetime.datetime(2022, 12, 15, 20, 21, 19, 109214, tzinfo=datetime.timezone.utc), 'unread': 0}
Any ideas on what is causing this and how can I remove it?

First I thought it was an error due to timezone rendering, tried setting USE_TZ = False, eventually imported tz_detect and timezone issue was fixed, but it seems that it is not what is causing this.
Also tried hiding the alert with js, with no success.
CodePudding user response：
try adding the following in you settings.py
LANGUAGE_CODE = "es-mx"
TIME_ZONE = "America/Mexico_City"
USE_I18N = True
USE_L10N = True
USE_TZ = True
CodePudding user response：
try changing this line in models.py
date = models.DateTimeField(default=timezone.now())
to
date = models.DateTimeField(default=timezone.now)
