how i can create order form

[Sarthak77tiwari]

please help me
I have four models of the shop, customer, product, an order.
I am showing the relation of models

shop

   user = models.OneToOneField(User, null=True, related_name='shop', blank=True, on_delete=models.CASCADE)
   name = models.CharField(max_length=70, null=True, default='shop', )
   address = models.CharField(max_length=70, null=True)
   Shop_category = models.CharField(max_length=200, null=True, )

customer

  user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)
  name = models.CharField(max_length=100, null=True, default='customer')
  Phone = models.PositiveIntegerField(blank=True, null=True)`

product

  shop = models.ForeignKey(Shop, models.CASCADE, null=True, blank=True)
  name = models.CharField(max_length=100, blank=True)
  Brand = models.CharField(max_length=200, blank=True)
  description = models.TextField(null=True, blank=True)

order

  shop = models.ForeignKey(Shop, models.CASCADE, null=True)
  customer = models.ForeignKey(Customer, models.CASCADE, null=True)
  product = models.ForeignKey(Product, models.CASCADE, null=True)
  quantity = models.CharField(max_length=30)
  date_created = models.DateTimeField(auto_now_add=True)
  status = models.CharField(max_length=200, choices=STATUS, default='Pending')
  note = models.CharField(max_length=1000, null=True)`

when customers login then the shop will print on the screen and a button on shop to show the products by the shop in the form card. On the product card, there is an order button that adds the product in order after submitting the selected product will print with the remaining filled of order. how I can create views.py
