looks like it works like this

the_max = Choice.objects.filter(date=date)
print max(the_max)

I need to learn how to use aggregation in django, I was thinking  on filter by date,
and then loop the query and make a dictionary with the name, and += value and then use the python max function.

Hi there,

  you could do it manually by counting occurrences or you could take a look at aggregation functions here: https://docs.djangoproject.com/en/1.7/topics/db/aggregation/

  Do as it suits your use case.

I am storing the information in the database 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.
