It’s not much work to do it manually:
from django.db import connection
items = Item.objects.filter(created_on__gte=datetime.now()-timedelta(days=7))
cursor = connection.cursor()
cursor.executemany("UPDATE myapp_item SET reddit_rank = %s WHERE id = %s",
[(reddit_rank(item), item.pk) for item in items])
cursor.close()
