DatetimeField 和 strftime 问题

Issue with DatetimeField and strftime

我想转换我的 DateTimeField :

download_date = models.DateTimeField(verbose_name=_('download date'), null=True)

strftime像这样:

from datetime import datetime, timedelta

last_download_temp = Download.objects.exclude(download_date=None).order_by('-download_date')[0]
print(f"Last download temp : {last_download_temp}")

last_download = last_download_temp.strftime('%Y-%m-%d %H:%M:%S')
print(f"Last download : {last_download}")

它returns :

Last download temp : 2019-01-07 09:10:01.509484+00:00

File "/home/Bureau/Projets/Publication/publication/src/web/freepub/views/main.py" in get_context_data
  236.             last_download = last_download_temp.strftime('%Y-%m-%d %H:%M:%S')

Exception Type: AttributeError at /freepub/stats
Exception Value: 'Download' object has no attribute 'strftime'

我不明白为什么它不起作用? 我需要先转换我的 last_download_temp 吗?

此处您使用的是 Download 对象,但它应该是 Download 对象的 download_date 属性。所以你应该这样做:

last_download = last_download_temp.download_date.strftime('%Y-%m-%d %H:%M:%S')
