It would be
unique_together = (('account', 'user__username'),)
if I understand what you’re trying to do. Note the double underscore. That’s how you look at a foreign key’s object’s properties.

I don’t believe you can do what you’re trying to do using django core. As pointed out in this answer to a related question unique_together is enforced at the DB layer. If you inspect the DB tables created by django model inheritance, you’ll see this isn’t possible for the DB to accomplish.
Take a look at that related question for some alternative solutions.

What you are missing is abstract = True in the base class. This creates a table with all the fields for the subclass.
- Where do things go when I ‘print’ them from my Django app?
- Unknown command: shell_plus and –settings
- Django grouping queryset by first letter?
