正在尝试 pass/fetch 条带 api 的数据

Question

我在 Rails 上对 Ruby 还很陌生，我一直在关注 tutorial 如何使用 Stripe 的 Connect API 实施在线市场。本教程将指导您如何进行单件商品购买，我试图超越本教程并创建一个市场，用户可以在其中购买多件商品并将它们放入购物篮并结账，这是一个很好的挑战，因为本教程的重点是一项。但是，我在结帐时卡住了 _form.html.erb.

之前，获取 publishable_key、

<%= form_with model: current_user, local: true, url: subscription_url, method: :post, html: { id: "payment-form", class: "stripe-form" }, **data: { stripe_key: product.user.publishable_key }**  do |form| %>

但现在因为我提交的是装满产品的购物车而不是一个单一的项目，所以 data: { stripe_key: } 现在功能失调。相反，我认为执行 data: { stripe_key: @account.publishable_key } 从数据库中获取 publishable_key 可能是个好主意，但它不起作用。

我很可能忘记了一些重要的事情。任何帮助都是合理的！

http://localhost:3000/subscription/new?account=4&amount=17

凯恩。

您的帐户 ID 似乎没有进入您的控制器。我希望 URL 看起来像这样（account_id 而不是 account）：

http://localhost:3000/subscription/new?account_id=4&amount=17

而且我希望 SubscriptionsController#new 查找 Account 模型而不是 User 模型，并使用相同的 account_id 参数：

@account = Account.find_by_id(params[:account_id])
