rails 4 个应用的 Stripe 优惠券未反映在费用中或保存在数据库中
Stripe coupon not reflected in charge or saved in database for rails 4 app
我们已经让 Stripe 在我们的 rails 4 应用程序中使用 Mastering Modern Payments 方法进行订阅支付。我们现在正在尝试添加优惠券。我们想使用 Stripe 来管理优惠券（在 Stripe 仪表板中创建优惠券）。
问题是当用户付款时，优惠券并没有减少收取的金额，也没有与用户和订阅信息一起保存到应用程序数据库中。我们没有收到任何错误。
工作原理：我们在用户支付时在哈希中看到优惠券代码，优惠券是在 Stripe 中设置的。总体而言，用户可以注册并支付罚款。我们在 Devise 中执行两步创建用户，然后让他们付款。当他们支付订阅费用时，我们的应用程序就会激活。
我们知道这里缺少优惠券的一部分，但我们正在努力弄清楚那是什么以及应该如何实施？我在 rails 中读到有关创建虚拟属性的信息，所以也许我们可以为优惠券这样做，因为目前在用户 table.
中没有任何优惠券信息
当用户注册订阅时，输出如下所示（实际数据已替换为发布）：

我们如何在费用中反映 Stripe 优惠券并将其保存在我们的应用程序数据库中？谢谢。
您的 CreateSubscription 服务不提供传递优惠券代码的途径。
您需要为此添加一个新参数，例如。
class CreateSubscription
def self.call(plan, email_address, token, coupon = nil)
# ...
subscription = Subscription.new(
plan: plan,
user: user,
coupon: coupon
)
# ...
end
end
此外，对于您提供的代码，还有一些其他事项需要注意：
customer = Stripe::Customer.create(
source: token,
email: user.email,
plan: plan.stripe_id,
coupon: subscription.coupon
)
Stipe 允许您对客户和订阅设置 coupon。计费时，应用于订阅的折扣会覆盖在客户范围内应用的折扣。参见 https://stripe.com/docs/api#subscription_object
因此，如果您的客户取消订阅，或有其他（多个）订阅。根据您的优惠券设置，他们也可能会获得折扣。
因此，根据您希望发生的情况，您可能只想将优惠券传递给 Stripe::Subscription 而不是传递给 Stripe::Customer。
