billing_agreement.cancel() 有问题。 ('cancel() 缺少 1 个必需的位置参数：'attributes')

Question

SDK/Library版本：1.13.1

环境：沙盒

PayPal-Debug-ID 值：None

语言、语言版本和OS：Python、Ubuntu

问题描述：当我尝试取消结算协议时出现以下错误。

错误：

TypeError: cancel() missing 1 required positional argument: 'attributes'

我的代码：

billing_agreement = BillingAgreement.find(billing_id)
    if billing_agreement.cancel():
        print(billing_agreement)
    else:
        flash('We are having some difficulties canceling your subscription, please try again later.', 'fails')
        return redirect(url_for('settings.settingspage'))

我收到错误是因为我需要属性值中的某些内容，但我不知道应该为变量分配什么。

Answer 1

经过一些挖掘和查看文档示例后，我找到了一个关于取消选项的示例，我需要分配给属性值的是 cancel_note.

代码：

cancel_note = {"note": "Canceling the agreement"}
user = Users.query.filter_by(id=ID).first()
billing_id = Subscriptions.query.filter_by(email=user.email).filter_by(active=1).first().order_id
billing_agreement = BillingAgreement.find(billing_id)
if billing_agreement.cancel(cancel_note):
    flash('Subscription canceled with success.', 'success')
    return redirect(url_for('settings.settingspage'))
else:
    flash('We are having some difficulties canceling your subscription, please try again later.', 'fails')
    return redirect(url_for('settings.settingspage'))
