由于您使用时区并且您正在“手动”创建日期时间对象，因此会记录该警告。我还建议您通过添加将警告变为错误：
import warnings
warnings.filterwarnings('error',
r"DateTimeField .* received a naive datetime",
RuntimeWarning, r'django\.db\.models\.fields')
在您的 settings.py 中，这样您可以更轻松地发现此类违规行为。
老实说，我不知道为什么，但实际上你的日期似乎不知道（如果你使用 timezone.is_aware()，它应该返回 false）。
要修复您当前的代码，我建议您使用 django utilis 来获取时区：
from django.utils import timezone
timezone.make_aware(yourdate, timezone.get_current_timezone())
在我的项目中，我为日期创建了一个实用程序类，因为我遇到了这样的问题，你可以看看（尤其是方法dateFromString）：
class DateUtils(object):
@classmethod

"""

:return: datetime: date

return timezone.make_aware(datetime.now(), timezone.get_current_timezone())

"""

:return: int: offset
"""
offset = cls.currentTimezoneDate().utcoffset()
return int(offset.total_seconds() / 60 / 60)
@classmethod
def UTCDate(cls, year, month, day, hour=0, minute=0, second=0, microsecond=0):
"""

:return: datetime: date

return timezone.make_aware(d, timezone.utc)
@classmethod
def asUTCDate(cls, date):
"""

return timezone.make_aware(datetime(date.year, date.month, date.day), timezone.utc)
if not timezone.is_aware(date):
return timezone.make_aware(date, timezone.utc)
return date.replace(tzinfo=timezone.utc)
