如何在 Django 中过滤 DateTimeField 的日期? [英] How can I filter a date of a DateTimeField in Django?

问题描述

我正在尝试过滤与日期比较的 DateTimeField.我的意思是:

I am trying to filter a DateTimeField comparing with a date. I mean:

MyObject.objects.filter(datetime_attr=datetime.date(2009,8,22))

我得到一个空的查询集列表作为答案，因为(我认为)我没有考虑时间，但我想要任何时间".

I get an empty queryset list as an answer because (I think) I am not considering time, but I want "any time".

在 Django 中有没有一种简单的方法可以做到这一点?

Is there an easy way in Django for doing this?

我设置了日期时间中的时间，不是00:00.

I have the time in the datetime setted, it is not 00:00.

推荐答案

此类查找在 django.views.generic.date_based 中实现如下:

Such lookups are implemented in django.views.generic.date_based as follows:

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

因为它非常冗长，所以计划使用 __date 运算符改进语法.查看#9596 将 DateTimeField 与日期进行比较太难"了解更多详情.

Because it is quite verbose there are plans to improve the syntax using __date operator. Check "#9596 Comparing a DateTimeField to a date is too hard" for more details.
