A QuerySet by aggregate field value

Question

Let\'s say I have the following model:

class Contest:
    title = models.CharField( max_length = 200 )
    description = models.TextField()

class Image:
            


        

Answer 1

You can write your own sort in Python very simply.

def getScore( anObject ):
    return anObject.score()
objects= list(Contest.objects.get( pk = id ).image_set)
objects.sort( key=getScore )

This works nicely because we sorted the list, which we're going to provide to the template.
