Comment:
Hello pierrenicolasr! As mentioned by David in the previous comment, we
would need a minimal Django project or a test case to reproduce this
issue. I see many tests in the Django test suite that are exercising
nested `OuterRef` calls and they are all passing:
{{{
$ grep -nr "OuterRef(OuterRef" tests/
tests/lookup/tests.py:1303:
Author.objects.filter(alias=OuterRef(OuterRef("name")))
tests/expressions/tests.py:675:
time=OuterRef(OuterRef("time")), pk=OuterRef("start")
tests/expressions/tests.py:688: inner =
SimulationRun.objects.filter(start=OuterRef(OuterRef("pk"))).values(
tests/expressions/tests.py:832:
lastname__startswith=Left(OuterRef(OuterRef("lastname")), 1),
tests/expressions/tests.py:861:
outer_lastname=OuterRef(OuterRef("lastname")),
tests/aggregation/test_filter_argument.py:171:
book_contact_set=OuterRef(OuterRef("pk")),
tests/aggregation/tests.py:1672:
name=OuterRef(OuterRef("publisher__name")),
}}}
So this error seems specific of the complex queries you mention. I'll mark
as `worksforme` for now but happy to reopen if you can provide a
reproducer. Thanks!
