Comment (by Sarah Boyce):
Updated the test to call values_list:
{{{
self.assertSequenceEqual(
ParkingLot4C.objects.order_by("name").values_list("name",
flat=True),
["Parking4A"]
)
}}}
And tested on 163a34ce4bc1086b346a52c7271f48d2c207f710 the original
commit, this also errors with `AttributeError: 'str' object has no
attribute '_meta'`.
In which case, we have never supported the lazy relationship case (note
that `parent = models.OneToOneField(Place, models.CASCADE,
parent_link=True)` passes).
