rewrite PostgreSQL query to Django ORM

Hello, how to rewrite this PostgreSQL query to Django ORM with no raw SQL ?


select * from finance_fund order by((select price from finance_nav where date='2016-11-08' and fund_id=finance_fund.id)/(select price from finance_nav where date='2016-11-07' and fund_id=finance_fund.id)) LIMIT 30;

So basically i need to order by division result of two simple queries of backward relations of Foreign key

Thanks in advance !
