I think you are trying to sum up the value of two model fields and store them in some other field.
so for that u can proceed from base. simple you just have to update that field in save method for example : *class Student(models.Model):* maths_score = models.DecimalField() english_score = models.DecimalFIeld() Total_score = models.DecimalField(default = 0) *def save(self, *args, **kwargs):* * self.Total_score = self.maths_score + self.english_score* super(Student, self).save(*args, **kwargs) or you can proceed with clean() method also.
