Django orm get latest for each group

Question

I am using Django 1.6 with Mysql.

I have these models:

class Student(models.Model):
     username = models.CharField(max_length=200, unique = True)

         


        

Answer 1

If your DB is postgres which supports distinct() on field you can try

Score.objects.order_by('student__username', '-date').distinct('student__username')
