django -- while time zone support is active
一、先看报错:
django 在处理datetime类型的的报错
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/db/models/fields/__init__.py:1451: RuntimeWarning: DateTimeField Person.birthday received a naive datetime (2017-12-02 08:02:02.776941) while time zone support is active.
二、问题分析:
1、默认情况下django中对时区的配置是UTC的、然而datetime中并没有明确指点时区、这样就冲突了。
三、解决方案1:
使用django提供的timezone类
import django import pytz from django.utils import timezone from datetime import datetime django.setup() from polls.models import Person p=Person() p.name='welson' p.birthday=timezone.now() p.save()
三、timezone和python内置的datetime的不同:
import django.timezone from datetime import datetime datetime.now() datetime.datetime(2017, 12, 2, 8, 37, 11, 354441) timezone.now() datetime.datetime(2017, 12, 2, 8, 36, 49, 310501, tzinfo=<UTC>)
