Django admin foreign key drop down field list only "test object"

Question

I have these two classes:

class Test(models.Model):
    id = models.AutoField(primary_key=True)
    user = models.ForeignKey(User)
    groups = models.ManyToManyField(Group)

class TestSubjectSet(models.Model):
    id =  models.AutoField(primary_key=True)
    test = models.ForeignKey(Test)
    subject = models.ManyToManyField(Subject)

The TestSubjectSet form test list shows only string "test object".

Answer 1

You have to add __unicode__(self) or __str__(self) methods in your models class.

Answer 2

Had the same problem. Adding

def __str__(self):
    return self.user

solved the problem.
