Django的DateTimeField警告

问题

lib\site-packages\django\db\models\fields\__init__.py:1418: RuntimeWarning: DateTimeField DispatchingPlan.start_time received a naive datetime (2022-03-01 16:00:
00) while time zone support is active.warnings.warn("DateTimeField %s received a naive datetime (%s)"

是一个跟时区有关的问题&＃xff0c;需要的是 active time&＃xff08;带时区的utc时间&＃xff09;&＃xff0c;但是收到的是 naive time&＃xff08;不带时区的utc时间&＃xff09;。

解决办法

1. &＃xff08;推荐&＃xff09;如果项目需要按时区显示&＃xff0c;获取时间的时候&＃xff0c;加上时区参数

   from django.utils import timezone
datetime.datetime(2013, 11, 20, 20, 8, 7, 127325,tzinfo&＃61;timezone.utc)


2. 如果项目不需要按时区显示&＃xff0c;就把 settings.py

   LANGUAGE_CODE &＃61; &＃39;zh-hans&＃39;
TIME_ZONE &＃61; &＃39;Asia/Shanghai&＃39;
USE_I18N &＃61; True
USE_L10N &＃61; True
# 这个改为 False
USE_TZ &＃61; False
