Description (last modified by )
Why upgrading to Django 3.0 I get the following issue:
subquery uses ungrouped column "t4.position" from outer query LINE 1: ..."."activity_type" AND ST_Contains(U2."locations", T4."positi...
It works fine in Django 2.2.8.

A quick diff of the query in both versions, shows a diff in the grouping section:
< GROUP BY "camps_offer"."id", "camps_provider"."id"
---
> GROUP BY "camps_offer"."id",
> (SELECT U0."id"
> FROM "camps_servicepackage" U0
> INNER JOIN "camps_region" U2 ON (U0."region_id" = U2."id")
> WHERE (U0."company_id" = 1 AND U0."option" = ("camps_offer"."activity_type") AND
> ST_Contains(U2."locations", (T4."position")))
> LIMIT 1), "camps_provider"."id"

I agree that there is probably some regression in such queries, but it's really hard to restore the original queryset from a raw SQL. Can you provide a queryset? If not I will try to reproduce this issue in our test suite.

I was able to reproduce this issue with attached test, thanks for the report.
Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80.
Reproduced at 972d93a95ec8b37fab84400417070b7439414967.

I think the correct solution here will be to make Subquery.get_group_by_cols return all its OuterRef expressions when alias is None; that is the ones contained in its annotations and where clause.
That would result in an additional GROUP BY T4."position" in the outer query as PostgreSQL expects.

Hey Simon, I have only limited experience with this part of the ORM, so I don't know if I can be of much help. However, I am happy to review anything you throw at me. Best -Joe

Note:
See TracTickets
for help on using tickets.
Can you provide a queryset? We'll not be able to reproduce this issue without it. Can you also confirm that it works with Django 2.2?
