     123    class User(models.Model):
     124        GENDER_MALE = 0
     125        GENDER_FEMALE = 1
     126        GENDER_CHOICES = [(GENDER_MALE, 'Male'), (GENDER_FEMALE, 'Female')]
     127        gender = models.IntegerField(choices=GENDER_CHOICES)
     128   
     129        def greet(self):
     130            return {self.GENDER_MALE: 'Hi, boy', self.GENDER_FEMALE: 'Hi, girl.'}[self.gender]
     131
