You probably need a single FK plus a meta option of unique_together https://docs.djangoproject.com/en/1.8/ref/models/options/#unique-together
Mike, Okay. What would be the correct syntax for PRIMARY KEY unique_together=('company', 'person', 'proj_nbr')
Use the model's clean() method ... https://docs.djangoproject.com/en/1.8/ref/models/instances/#django.db.models.Model.clean
This I'll need to ponder more to figure out where to put the clean method so it validates entries before they're saved. Thanks, Rich
