Having "make_aware expects a naive datetime" while migrate - mysql

Question

I have developed an application with Django.
This is working fine in my PC with sqlite backend.
But when I am trying to go live with linux server and mysql backend then I am getting bellow error while first time migration.
(env-bulkmailer) [root#localhost bulkmailer]# python3 manage.py migrate
Traceback (most recent call last):

In settings-
USE_TZ = True
I have run mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql also as django doc.
I am using django 4.1.3 and mysql community 8.0.30
Thanks in advance.

Ran into the same issue. At some point, django assumes that the the data is timezone-naive without checking. Here's the work-around.
Update the make_aware function that is listed in your stack trace here:
/var/www/bulkmailer-folder/env-bulkmailer/lib64/python3.9/site-packages/django/utils/timezone.py", line 291, in make_aware
Instead of raising an error if the value is already aware, just return the aware value. See the last else statement below.
def make_aware(value, timezone=None, is_dst=NOT_PASSED):
"""Make a naive datetime.datetime in a given time zone aware."""
if is_dst is NOT_PASSED:
is_dst = None
else:
warnings.warn(
"The is_dst argument to make_aware(), used by the Trunc() "
"database functions and QuerySet.datetimes(), is deprecated as it "
"has no effect with zoneinfo time zones.",
RemovedInDjango50Warning,
)
if timezone is None:
timezone = get_current_timezone()
if _is_pytz_zone(timezone):
# This method is available for pytz time zones.
return timezone.localize(value, is_dst=is_dst)
else:
# Check that we won't overwrite the timezone of an aware datetime.
if is_aware(value):
# ADD THIS
return value
# REMOVE THE FOLLOWING LINE
# raise ValueError("make_aware expects a naive datetime, got %s" % value)
# This may be wrong around DST changes!
return value.replace(tzinfo=timezone)
