无法比较天真和知道datetime.now（）< = challenge.datetime_end [英] Can't compare naive and aware datetime.now() <= challenge.datetime_end

问题描述

我想使用比较运算符比较当前日期和时间与模型中指定的日期和时间：

I am trying to compare the current date and time with dates and times specified in models using comparison operators:

if challenge.datetime_start <= datetime.now() <= challenge.datetime_end:

脚本错误与：

TypeError: can't compare offset-naive and offset-aware datetimes

这些模型如下所示：

class Fundraising_Challenge(models.Model):
    name = models.CharField(max_length=100)
    datetime_start = models.DateTimeField()
    datetime_end = models.DateTimeField()

我也有django使用区域设置的日期和时间。

I also have django using locale date and times.

't能够找到是django用于DateTimeField（）的格式。是天真还是意识？如何获得datetime.now（）来识别locale datetime？

What I haven't been able to find is the format django uses for DateTimeField(). Is it naive or aware? And how do I get datetime.now() to recognize locale datetime?

推荐答案

datetime.datetime。

datetime.datetime.now is not timezone aware.

Django提供了一个辅助程序，需要 pytz

Django comes with a helper for this, which requires pytz

from django.utils import timezone
now = timezone.now()

您应该能够比较现在到 .datetime_start
