moments.models.py:

class Reply(models.Model):
    status = models.ForeignKey(Status,models.CASCADE)
    author = models.CharField(max_length=50)
    type = models.CharField(max_length=20,choices=[("0","like"),("1","comment")])
    at_person = models.CharField(max_length=50,null=True,blank=True)
    text = models.CharField(max_length=280,null=True,blank=True)

    def __str__(self):
        return "{} on {}".format(self.author,self.status.text)
