The following test (added to `tests/queries/test_qs_combinators`) fails
when trying to exclude results using OuterRef()
{{{
def test_exists_exclude(self):
# filter()
qs = Number.objects.annotate(
foo=Exists(
Item.objects.filter(tags__category_id=OuterRef('pk'))
)
).filter(foo=True)
print(qs) # works
# exclude()
qs = Number.objects.annotate(
foo =Exists(
Item.objects.exclude(tags__category_id=OuterRef('pk'))
)
).filter(foo=True)
print(qs) # crashes
# filter(~Q())
qs = Number.objects.annotate(
foo =Exists(
Item.objects.filter(~Q(tags__category_id=OuterRef('pk')))
)
).filter(foo=True)
print(qs) # crashes
}}}
It results in the following error
{{{
ValueError: This queryset contains a reference to an outer query and may
only be used in a subquery
}}}
