I'm trying to render out the get_cart_total to the email template I'm working on, which gets sent when the success view is triggered and the boolean is True, currently it gets an error message saying 'WSGIRequest' object has no attribute 'order', what's causing this and how do I fix it? Model

class Customer(models.Model):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, blank=True, null=True)
    email = models.EmailField(max_length=150)

class Order(models.Model):
    customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, blank=True, null=True)

    @property
    def get_cart_total(self):
        orderitems = self.orderitem_set.all()
        total = sum([item.get_total for item in orderitems])
        return total

Views

def success(request):
    if order.complete == True:
        email = request.user.customer.email
        
        #error
        cart_total = request.order.get_cart_total
        
        html_message = render_to_string('check/emails/test.html', {'cart_total': cart_total})
        recipient_list = [email, ]
        send_mail( subject, plain_message, email_from, recipient_list, html_message=html_message )
