条带令牌未携带到控制器导轨4

问题

我已经测试了CoffeeScript，并且表单调用Stripe，使用正确的响应令牌设置隐藏字段并提交表单。 我的问题是，一旦提交控制器似乎没有正确获取令牌并抛出此错误： Stripe :: InvalidRequestError – 您必须提供卡或客户ID 。

接下来，我累了拿出生成的令牌并将其硬编码到控制器中，看看是否可行。 我提交了表格，在Stripes结束时收到了付款。 关于接下来要尝试什么，我几乎没有想法。 我想知道我是否遗忘了某些东西或遗漏了某些东西，因为付款是在作业下嵌套的。

Answer 1

我看到至少有两个问题。 我想在进展之后可能会有更多。

1. 您无权访问#save_with_payment params

   问题发生在这一行：

    # Get the credit card details submitted by the form token = params[:stripe_customer_token] 

   params受strong_params保护，您无法访问它。

   修复是允许payment_params所有需要的参数，并在此方法中重复使用它。

2. 实际上你在#create没有@price

   此问题与问题无直接关系，但存在。

   这个实例变量@price在#new 。 而#create是另一个实例，所以你不能再拥有它。

   解决方法是从payment_params获取它
