Ruby on rails 缺少必需的参数：卡

在设置以便用户可以在文件中为Stripe创建新卡的过程中，我在/subscriptions/changecard上获得了一个

Stripe:：InvalidRequestError。错误消息是
缺少必需的参数：card
，并指向行
@customer.cards.create（{:card=>@user.subscription.stripe\u card\u token}）

如果用户有订阅，他们应该能够访问/subscriptions/changecard并填写表格，以添加新卡

订阅控制器：

  def new
    plan = Plan.find(params[:plan_id])
    @subscription = plan.subscriptions.build
    if params[:PayerID]
      @subscription.paypal_customer_token = params[:PayerID]
      @subscription.paypal_payment_token = params[:token]
      @subscription.email = @subscription.paypal.checkout_details.email
    end
  end

  def create
    @subscription = Subscription.new(params[:subscription])
    if @subscription.save_with_payment
      redirect_to @subscription, :notice => "Thank you for subscribing!"
    else
      render :new
    end
  end

  def show
    @subscription = Subscription.find(params[:id])
  end

  def paypal_checkout
    plan = Plan.find(params[:plan_id])
    subscription = plan.subscriptions.build
    redirect_to subscription.paypal.checkout_url(
      return_url: new_subscription_url(:plan_id => plan.id),
      cancel_url: root_url
    )
  end

    def updatesubscription
      @user = current_user
      @customer = Stripe::Customer.retrieve(@user.subscription.stripe_customer_token)
      @customer.update_subscription(:plan => "1", :prorate => true)
     current_user.save!
      flash.alert = 'Your subscription has been updated!'
      redirect_to root_url
     end

     def cancelsubscription
       @user = current_user
         @customer = Stripe::Customer.retrieve(@user.subscription.stripe_customer_token)
         @customer.cancel_subscription()
         current_user.save!
         flash.alert = 'Your subscription has been cancelled successfully!'
         redirect_to root_url
       end

       def showcard
         @user = current_user
         Stripe::Customer.retrieve(@user.subscription.stripe_customer_token).cards.all()
       end

        def changecard
       @user = current_user       
       @customer = Stripe::Customer.retrieve(@user.subscription.stripe_customer_token)

         card = @customer.cards.create({
           :card => @user.subscription.stripe_customer_token
         })

         @customer.default_card = card
         @customer.save
       end
end

如果将无效令牌传递给
卡
密钥，则会抛出
条带：：InvalidRequestError
。您能否验证
@user.subscription.stripe\u card\u token
是否输出了有效值？@zeantsoi我相信您是对的，card\u token不存在。API说使用
customer.cards.create（{:card=>TOKEN\u ID}）
所以我就这样想出了这行代码。我不确定我应该做什么，因为在我的数据库中，我只有
stripe\u customer\u token
，它等于客户id。看起来你更新卡的方式不对。文档说明：我可以使用
@customer.default\u card=card
来实现这一点。当我将原始代码更改为默认卡时，
card=@customer.cards.create的令牌id无效。我更新了代码以显示最新版本。使用新代码，新卡将保存为默认值，但用户将有多张卡存档。除非最好的方法是让用户删除他们的卡片，然后添加一张新的。我将不得不集思广益，看看如何在不删除订阅的情况下进行。
