Thanks for your reply.
The model.py contains,
class SignUp(models.Model):
email = models.EmailField()
full_name = models.CharField(max_length = 120, blank = True, null =
True)
timestamp = models.DateTimeField(auto_now_add = True, auto_now = False)
updated = models.DateTimeField(auto_now_add = False, auto_now = True)
def __unicode__(self): #__str__ for python3
return self.email
I had to add the updated field,
updated = models.DateTimeField(auto_now_add = False, auto_now = True)
Running make migrations,
