Comment:
If it helps, while checking if #34945 was a duplicate of this I was able
to boil down the failure to this simple example:
{{{
class Foo(Model):
name = CharField()
class Bar(Model):
name = CharField()
qs = (
Foo.objects.annotate(alias=F("name"))
.union(Bar.objects.annotate(alias=F("name")))
.values("alias")
)
print(qs)
}}}
gives
{{{
<QuerySet [{'alias': 1}, {'alias': 1}]>
}}}
