I have a django model with a DateTimeField.

class Point(models.Model):
    somedata = models.CharField(max_length=256)
    time = models.DateTimeField()

I want to get a count of the number of these objects for each day. I can do this with the following SQL query, but don't know how to do it through django.

SELECT DATE(`time`), Count(*)
FROM `app_point`
GROUP BY DATE(`time`)

Being able to restrict the results to a date range would also be good.
