I have this model:
class Person(models.Model):
city = models.CharField(max_length=20, blank=True)
added_date = models.DateField(default=datetime.date.today)
I want to create a template/view that has a table of months and the number of people added that month (ie, 5 in january, 10 in february, 8 in march, etc.). I have a similar table for all the people from a each city using:
cities = Patient.objects.values('city').annotate(city_count=Count('city')).order_by('-city_count')
I don't know how to do that for my months table. I could filter for a particular month, then count all. But then I'd need to run that through a loop over every month, which would be multiple database hits. I don't want to do that.
Is there a way to do this without writing sql and just using django's api?
