我正在使用带有rails 3的Paypal重复宝石。
我有三种类型的订阅包和一些附加包，这样用户就可以订阅一些附加功能。

参考paypal重复出现的宝石，我找不到Paypal Line项目。我查看了Github上的代码，但我不确定如何修改源代码。
options = options.reverse_merge(
token: @subscription.paypal_payment_token,
description: @subscription.package_plan.description,
payer_id: @subscription.paypal_customer_token,
frequency: @subscription.package_plan.recurring_frequency,
item_name: @subscription.package_plan.name,
item_quantity: 1,
item_amount: @subscription.package_plan.price * @subscription.package_plan.recurring_frequency,
item_name: @subscription.package_add_ons.first.name,
item_quantity: 1,
item_amount: @subscription.package_add_ons.first.price * @subscription.package_plan.recurring_frequency,
amount: @subscription.package_plan.price * @subscription.package_plan.recurring_frequency,
currency: @subscription.package_plan.currency
)
