Description (last modified by )
I have a query like:
In [6]: Shop.objects\
...: .annotate(product_count = Count('ShopProduct'))\
...: .filter(product_countgt=1)\
...: .order_by('?')
Out[6]: <QuerySet []>
but the out put is empty!
if i remove order_by('?') it works, and the same for the filter(product_countgt=1).
I get the SQL from connection.queries:
SELECT ..., COUNT("nakhll_market_product"."ID") AS "product_count" FROM "nakhll_market_shop" LEFT OUTER JOIN "nakhll_market_product" ON ("nakhll_market_shop"."ID" = "nakhll_market_product"."FK_Shop_id") GROUP BY "nakhll_market_shop"."ID", RANDOM() HAVING COUNT("nakhll_market_product"."ID") > 1 ORDER BY RANDOM() ASC
but this SQL works correctly:
SELECT
... ,
COUNT("nakhll_market_product"."ID") AS "product_count"
FROM "nakhll_market_shop"
LEFT OUTER JOIN
"nakhll_market_product" ON ("nakhll_market_shop"."ID" = "nakhll_market_product"."FK_Shop_id")
WHERE ("nakhll_market_shop"."Available" AND "nakhll_market_shop"."Publish")
GROUP BY "nakhll_market_shop"."ID" HAVING COUNT("nakhll_market_product"."ID") > 1
ORDER BY RANDOM()
