Question

我正在使用Pinax-Stripe开发一个django应用程序。在我的模型中有这个代码：

class Plan(StripeObject):
    amount = models.DecimalField(decimal_places=2, max_digits=9)
    currency = models.CharField(max_length=15)
    interval = models.CharField(max_length=15)
    interval_count = models.IntegerField()
    name = models.CharField(max_length=150)
    statement_descriptor = models.TextField(blank=True)
    trial_period_days = models.IntegerField(null=True)
    def __str__(self):
         return  "{} ({}{})".format(self.name,            CURRENCY_SYMBOLS.get(self.currency, ""), self.amount)

现在您知道在模型中，我们可以使用Model.objects.get(id=pk)

选择数据

但是当我在这个'StripeObject'中使用相同的内容时，它会给我一个未定义的错误。有谁知道如何从这个'Stripe Object'模型中选择数据？

这是views.py的代码：

class SubscriptionCreateView(LoginRequiredMixin, PaymentsContextMixin, CustomerMixin, FormView):
    template_name = "pinax/stripe_b/subscription_create.html"
    form_class = PlanForm

    def set_customer(self):
        if self.customer is None:
            self._customer = customers.create(self.request.user)

    def subscribe(self, customer, plan, token):
        subscriptions.create(customer, plan, token=token)

    def form_valid(self, form):
        self.set_customer()
        try:
            self.subscribe(self.customer, plan=form.cleaned_data["plan"], token=self.request.POST.get("stripeToken"))
            #added code starts here
            current_user = self.request.user           
            user_space = Space.objects.get(user = current_user)
            user_space.available_harddrive = 1024
            user_space.available_ram = 1024
            user_space.save()
            plan=form.cleaned_data["plan"]
            plan_pk = Plan.get(id = plan.pk)

            #added code ends here    
            return redirect("pinax_stripe_subscription_list")
        except stripe.StripeError as e:
            return self.render_to_response(self.get_context_data(form=form, errors=smart_str(e)))

这就是我遇到问题的地方：

 plan=form.cleaned_data["plan"] 
 plan_pk = Plan.get(id = plan.pk)

如何在django中选择'条纹对象'中的数据，就像在模型中一样？
