Query datetime by today's date in Django
Question:
I’m saving datetime in the db for an object. I’d like to query against the db and select anything from todays date, not datetime.
What’s the easiest way to do this? This doesn’t work:
invoice_for_today = Invoice.objects.get(user=user, date=date.today())
Answers:
Try using the keys date__gte and date__lte. You can pass in two datetime objects marking the boundaries of what you want to match.
I remember there being plans to add a __date field lookup to make this easier, but as it stands the “standard” way of doing it is
today_min = datetime.datetime.combine(datetime.date.today(), datetime.time.min)
today_max = datetime.datetime.combine(datetime.date.today(), datetime.time.max)
Invoice.objects.get(user=user, date__range=(today_min, today_max))
You can also do something like this:
today = date.today()
invoice_for_today = Invoice.objects.filter(date__year=today.year, date__month=today.month, date__day=today.day)
obj = TeachersPlanner.objects.filter(date__startswith=date.today())
There is a new __date field lookup in Django 1.9 you can use:
Entry.objects.filter(pub_date__date=datetime.date(2005, 1, 1))
Entry.objects.filter(pub_date__date__gt=datetime.date(2005, 1, 1))
in django<1.9
from django.utils.timezone import datetime #important if using timezones
today = datetime.today()
foo_for_today = Foo.objects.filter(datefield__year=today.year, datefield__month=today.month, datefield__day=today.day)
in django>1.9, as they added the date keyword
foo_for_today = Foo.objects.filter(datefield__date=datetime.date.today())
To get entries from the Last 24 hours you can use:
from datetime import datetime, timedelta
Entry.objects.filter(pub_date__gte = datetime.now() - timedelta(days=1))
