I didn't quite understood the question, you want to find the division of
two prices for each item, but each item has only one price according to the
model you posted.
can you express what you want to accomplish in python or SQL?

Hello
Is it possible to do in ORM or in PostgreSQL
Assume we have a table with date and price
# class Item(models.Model):
#price = models.DecimalField()
#date = models.DateField()
We need for every item in table find division of two prices by two dates
and then order_by that result of
2 matches
