<s>[INST] How can I filter a date of a DateTimeField in Django? I am trying to filter a DateTimeField comparing with a date. I mean:
MyObject.objects.filter(datetime_attr=datetime.date(2009,8,22))

I get an empty queryset list as an answer because (I think) I am not considering time, but I want "any time".
Is there an easy way in Django for doing this?
I have the time in the datetime setted, it is not 00:00.
 [/INST] 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))} 

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.
