16732	Unable to have abstract model with unique_together	Mitar	Can Sarıgöl	"I have such model definition:

{{{
class SlugVersion(models.Model):
    class Meta:
        abstract = True
        unique_together = (('slug', 'version'),)

    slug = models.CharField(db_index=True, max_length=10, editable=False)
    version = models.IntegerField(db_index=True, editable=False)

class Base(SlugVersion):
    name = models.CharField(max_length=10)

class Test(Base):
    test = models.IntegerField()
}}}

And I am getting:

{{{
Error: One or more models did not validate:
test.test: ""unique_together"" refers to slug. This is not
in the same model as the unique_together statement.
test.test: ""unique_together"" refers to version. This is not
in the same model as the unique_together statement.
}}}

I see this is as a bug. Why there could not be a table for class `Base` with unique constraints on its `slug` and `version` fields, and then 1-1 relationship with additional table for model `Test` with field `test`."
