[Fixed]-Django – display both fields for a unique together model

unique_together isn’t a compound primary key. It’s just a compound constraint. Your model still has a hidden, autogenerated id field which is the real primary key.

Yes, you can set up __str__ to output whatever you want so long as it’s a string. It doesn’t have to be unique, but it really helps if it is. (BTW, I’m not sure which Python you’re using or if this changes in Python 3, but it’s recommended to use __unicode__ instead of __str__.)

def __unicode__(self):
    return "{0} (from {1})".format(self.name, self.supplier)

But again, this isn’t your actual primary key. To see that as well (not really recommended, because it’s noise):

def __unicode__(self):
    return "{0} (from {1}) (#{2})".format(self.name, self.supplier, self.id)
