Comment:
Thanks for the report, it's related with using lookup that are not
transforms, e.g. `isnull`
{{{
def test_ordering_pointing_to_lookup_not_transform(self):
class Model(models.Model):
test = models.CharField(max_length=100)
class Meta:
ordering = ('test__isnull',)
self.assertEqual(Model.check(), [])
}}}
