class Emp(models.Model):
    full_name = models.CharField(max_length=100)
    mobile = models.CharField(max_length=10,blank=True,null=True)
    email = models.EmailField(blank=True,null=True)

class Enquiry(models.Model):
    date = models.DateField(default=timezone.now)
    number = models.AutoField(primary_key=True)
    products = models.ManyToManyField(Product, related_name="products") 
    referred_by_emp = models.ForeignKey(
        Emp,related_name='ref_emp',
        null=True,blank=True,
        )
class Emp(models.Model
