Hello guys! Currently I have a problem with sorting of distinct rows from my table(I want to sort by only one field that is not present in distinct()) and found solution that is written on raw SQL. I am newbie so I don't know how should I do the same construction, but in python-gino:

SELECT * FROM 
 (SELECT DISTINCT ON (address_id) purchases.address_id, purchases.* 
 FROM "purchases" 
 WHERE "purchases"."product_id" = 1 ORDER BY address_id DESC ) 
ORDER BY purchased_at DESC

Thanks in advance
