Python 官方 Stripe 客戶端創建兩個客戶

Question

我在下面使用的這段代碼運行良好，除了結帳完成時，我注意到每次有人在我的網站上結帳時都會輸入兩個客戶條目。

一個有默認源集，一個沒有。 我附上了截圖。

def checkout(request):
    if request.method == 'POST':
        plan = Plan.objects.get(nickname=request.POST['plan'])
        stripe_customer = stripe.Customer.create(
            email=request.user.email, source=request.POST['stripeToken'])

        stripe_subscription = stripe.Subscription.create(customer=stripe_customer.id,
                                                         items=[
                                                             {'plan': plan.id}],
                                                         trial_from_plan=True)
        # Tried removing but no the reason for the issue.
        Subscription.sync_from_stripe_data(
            stripe_subscription
        )
        return redirect('settings')
    else:
        if request.method == 'GET':
            plan = Plan.objects.get(nickname=request.GET['plan'])
        return render(request, 'plans/checkout.html',
                      {'plan': plan, 'price': '0'})

我嘗試將 {'plan': plan.id} 更改為 {'plan': plan} 並出現錯誤：

請求 req_0WL0lW2orGwLMV：沒有這樣的計划：家庭； 存在一個名稱為 Family，但其 ID 為 plan_H5fvA8jJ0qX9qF。

編輯： dj-stripe+webhooks 正在使用，但我需要使用官方 API 創建客戶。 似乎在（出於某種原因）創建訂閱之后最后創建了重復的客戶（沒有付款來源）

        plan = Plan.objects.get(nickname=request.POST['plan'])

        # Create the stripe Customer, by default subscriber Model is User,
        # this can be overridden with settings.DJSTRIPE_SUBSCRIBER_MODEL
        stripe_customer, _ = Customer.get_or_create(
            subscriber=request.user)

        # Using the Stripe API, create a subscription for this customer,
        # using the customer's default payment source

        stripe_customer.add_card(request.POST['stripeToken'])

        # Sync the Stripe API return data to the database,
        # this way we don't need to wait for a webhook-triggered sync
        Subscription.sync_from_stripe_data(
            stripe_subscription
        )
        return redirect('settings')
    else:
