I've got this model:
class Visit(models.Model):
timestamp = models.DateTimeField(editable=False)
ip_address = models.IPAddressField(editable=False)
If a user visits multiple times in one day, how can I filter for unique rows based on the ip field? (I want the unique visits for today)
today = datetime.datetime.today()
yesterday = datetime.datetime.today() - datetime.timedelta(days=1)
visits = Visit.objects.filter(timestamp__range=(yesterday, today)) #.something?
EDIT:
I see that I can use:
Visit.objects.filter(timestamp__range=(yesterday, today)).values('ip_address')
to get a ValuesQuerySet of just the ip fields. Now my QuerySet looks like this:
[{'ip_address': u'127.0.0.1'}, {'ip_address': u'127.0.0.1'}, {'ip_address':
u'127.0.0.1'}, {'ip_address': u'127.0.0.1'}, {'ip_address': u'127.0.0.1'}]
How do I filter this for uniqueness without evaluating the QuerySet and taking the db hit?
# Hope it's something like this...
values.distinct().count()
