django时间查询

1、gt：大于某个时间

now = datetime.datetime.now()

#前一天

start = now – datetime.timedelta(hours=23, minutes=59, seconds=59)

a=yourobject.objects .filter(youdatetimcolumn__gt=start)

2、gte：大于等于某个时间：

a=yourobject.objects .filter(youdatetimcolumn__gte=start)

3、lt：小于

a=yourobject.objects .filter(youdatetimcolumn__lt=start)

4、lte：小于等于

a=yourobject.objects .filter(youdatetimcolumn__lte=start)

5、range：查询时间段

start_date = datetime.date(2005, 1, 1)

end_date = datetime.date(2005, 3, 31)

Entry.objects.filter(pub_date__range=(start_date, end_date))

6、year：查询某年

Entry.objects.filter(pub_date__year=2005)

7、month：查询某月

Entry.objects.filter(pub_date__month=12)

8、day：某天

Entry.objects.filter(pub_date__day=3)

9、week_day：星期几

Entry.objects.filter(pub_date__week_day=2)

10、获取今天的日期，日期格式为yyyy-MM-dd

from django.utils.timezone import now, timedeltadate = now().date() + timedelta(days=-1) #昨天date = now().date() + timedelta(days=0) #今天date = now().date() + timedelta(days=1) #明天
