尝试为条带 api 传递/获取数据

Question

我对 Ruby on Rails 还很陌生，我一直在关注tutorial，了解如何使用 Stripe 的 Connect API 实现在线市场。本教程将指导您如何购买单件商品，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帐，这是一个很好的挑战，因为本教程专注于一项。但是，我在结帐时卡住了_form.html.erb。

之前，要获取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| %>

但现在因为我要提交一个装满产品的购物车而不是单个项目，data: { stripe_key: } 现在功能失调。相反，我认为使用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

错误

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 会查看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])
