I have model Shop, Product, Customer, Order. the relation of model
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)`

customer
`
class Customer(models.Model):

          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
`
class Product(models.Model):

           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
`
class Order(models.Model):
STATUS = (
('Pending', 'Pending'),
('Out for delivery', 'Out for delivery'),
('Delivered', 'Delivered'),
)
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')`
when customers login then the list of shops 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 an order so that the customer in order is the instance and the shop in order is that shop which is selected to show the products, and products which are selected for the order, please explain me
