unit_price = models.DecimalField(max_digits=10, decimal_places=2,
default='0', blank=True, null=True)
quantity = models.IntegerField(default='0', blank=True, null=True)
total_price = models.DecimalField(max_digits=10,
decimal_places=2,default=1)
reorder_level = models.IntegerField(default='0', blank=True, null=True)
def save(self, *args, **kwargs):
