Description (last modified by Ronny Vedrilla)

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

Hello Ron,

Could you provide an exact reproduction case for your issue. From a quick look your models are not valid because field1 and field2 are not defined on your abstract model.
