django - TypeError: coercing to Unicode

Question

I'm getting TypeError: coercing to Unicode: need string or buffer, int found

This is my models.py:

class FollowingModel(models.Model):
    user = models.ForeignKey(User)
    person = models.IntegerField(max_length=20, blank=False)

    def __unicode__(self):
            return self.person

When I retrieve the values from the FollowingModel in my views like this

g = FollowingModel.objects.all()
g[0] -----> I'm getting that error

I tried changing the def __unicode__(self): as

def __unicode__(self):
    return str(self.person)

But no use, still I'm getting the same error. Could anyone guide me?

Thanks!

UPDATE

>>>g = FollowingModel.objects.all()
>>>g

Traceback (most recent call last):

Answer 1

The __unicode__ method should return just that, unicode:

def __unicode__(self):
    return unicode(self.person)
