New description:
I added a `unique_together` constraint on my abstract model like this:
{{{
class InvoicingDocument(models.Model):
field1 = models.IntegerField()
field2 = models.IntegerField()
class Meta:
abstract = True
unique_together = (('field1', 'field2'),)
class Invoice(InvoicingDocument):
pass
}}}
When I run `manage.py makemigrations` the migration file does not contain
any information about adding the index to the model `Invoice`.
When I add it to the child-class, it works.
I guess this is an issue with `django-migrations`?
Best regards
Ronny
