22356	unique_together fails when referencing columns from base and child class	Claus Conrad	Marc Egli	"Not sure whether this bug belongs to ""System checks"", ""ORM"" or ""Migrations"", but thought I'd report it:

class Foo(models.Model):
    url = models.URLField(""URL"", blank=True)

class Bar(Foo):
    blip = models.CharField(max_length=10)
    class Meta:
        unique_together = (
            'url',
            'blip'
        )
