Django filter on TimeField

问题

In my model I have a TimeField:

time = models.TimeField(db_index=True)

Now I have to filter by this value: for example I need to make something like: time == "12:30"

**** EDIT *****

I need also to make something like: time is in a range : from 12:15 to 12:15

How can I make it?

回答1:

You can do something like this:

YourModel.objects.filter(time__contains='16:23')

If you use this instead:

YourModel.objects.filter(time='16:23')

You will never find it since TimeField objects are save including milliseconds: datetime.time(16, 23, 23, 952151)

Edit:

Ok, assuming you have strings you can do something like this:

begin = datetime.datetime.strptime('12:14', '%H:%M').time()
end = datetime.datetime.strptime('12:16', '%H:%M').time()
result = YourModel.objects.filter(time__range=(begin, end))
