from django.db import models


class product(models.Model):
    prodid = models.IntegerField(("ID"))
    name = models.CharField(("Product Name"), max_length=100,unique ="true")
    price = models.IntegerField()
    star = models.IntegerField()


    def __str__(self):
        return self.name 


    class cart (models.Model):
        product = models.ForeignKey(product , on_delete=models.CASCADE)
        quantity = models.IntegerField()
        address = models.CharField(("Address"), max_length=300, default='')
