What is the method for utilizing a field variable in a model that is connected with a ForeignKey?

edit

To utilize a field variable in a model that is connected with a ForeignKey, you can use the dot notation to access the related model and its fields. For example, if you have a model called Customer with a ForeignKey connection to a model called Order, and you want to access the name of the customer who placed the order, you can do the following:

class Customer(models.Model):
    name = models.CharField(max_length=100)
    ...

class Order(models.Model):
    customer = models.ForeignKey(Customer, on_delete=models.CASCADE)
    order_date = models.DateField()
    ...

# To access the name of the customer who placed the order:
order = Order.objects.first()
customer_name = order.customer.name

In this example, we first get an instance of the Order model and then use the customer field to access the related Customer model. We can then use the name field of the Customer model to access the customer's name.
