looks like it works like this

class Choice(models.Model):
restaurant = models.ForeignKey(Restaurant)
person = models.ForeignKey(Person)
date = models.DateField("time published")
time = models.TimeField("date published")
that way I can get the person and the restaurant. and will look like in the attached pictures, now how can I query.the max repeated restaurant id, for today date.I want to know today what restaurant won. =) (I am trying to even think on how to get this in a regular sql command)thanks guys.
