Ruby on rails 使用paypal Recurtive gem升级订阅计划

我已经为Stripe做了这个设置，但我似乎无法为PayPal循环gem找到它。我希望允许用户切换他们的付款计划。如果用户订阅了1个月的订阅（计划id 1），他们应该能够升级到年订阅（计划id 12）

任何帮助都将不胜感激

不幸的是，无法在PayPal上更新或更改订阅条款。必须取消此订阅并设置新订阅

对于

UpdateRecurringPaymentsProfile

您需要计算按比例分配的差额，并在设置新配置文件时向他们收取

INITAMT

，然后设置新

AMT

的开始日期，该日期将在他们的期限到期后收集

编辑：这是假设您正在使用。因为我找不到任何地方，它会自动为您执行此操作。

谢谢。这是不幸的。我将尝试按比例设置。谢谢@xps15z你找到答案了吗？
