Question

我正在尝试过滤我的前两个IF语句，以仅显示今天当前日期从上午8点到上午10点的当前日期，现在只是日期，我需要将date = date更改为created_at =”，但是将在一定范围内完成。这是我的views.py。如何将此添加到我的IF语句中？谢谢

views.py

Answer 1

今天过滤器

today_date = datetime.datetime.now().date()

.filter(your_datetime_field__date = today_date)

小时过滤器

.filter(your_datetime_field__hour__lte = 10).filter(your_datetime_field__hour__gte = 8)

请记住，此查询的结果也将是10:59:59。如果您只需要8:00:00-9:59:59，请使用lt代替lte

按时间范围过滤创建日期
