Django模型时程滤波方法

我自己也很困惑,但我想我已经解决了 the documentation about the range lookup option 很有帮助。

当您这样做时:

YourModel.objects.filter(datetime_published__year='2008', 
                     datetime_published__month='03', 
                     datetime_published__day='27')

SELECT ... WHERE EXTRACT('year' FROM pub_date) = '2008'
             AND EXTRACT('month' FROM pub_date) = '03'
             AND EXTRACT('day' FROM pub_date) = '27';

鉴于django基于日期的通用视图的这一部分:

{'date_time_field__range': (datetime.datetime.combine(date, datetime.time.min),
                        datetime.datetime.combine(date, datetime.time.max))}

变得像:

YourModel.objects.filter(datetime_published__range=(
                datetime.datetime.combine('2008-03-27',datetime.time.min),
                datetime.datetime.combine('2008-03-27',datetime.time.max)
                                                                  )

SELECT ... WHERE datetime_published BETWEEN '2008-03-27 00:00:00'
                                        AND '2008-03-27 23:59:59';

(上一个SQL示例中的时间戳的格式显然是错误的,但是您明白了)

希望能回答你的问题:)
