class Year(models.Model):

class Month(models.Model):

(1 , "Jan"),
(2, 'Feb'),
(3, 'March'),
(4, 'April'),
(5, 'May'),

(7, 'July'),

month = models.PositiveSmallIntegerField(choices = MONTH_CHOICE)
year = models.ForeignKey(Year, on_delete= models.SET_NULL)
class Student(models.Model):

admission_month = models.ForeignKey(Month, on_delete=models.SET_NULL)
