Rails：控制器/创建-如何编写if创建成功

问题描述

我当前正在构建一个使用条带化的应用程序，当付款成功时，用户将遵循 redirect_to session.delete（：return_to）。付款失败或出现错误时，如何控制用户去向何处？

也许我需要一个if语句？如果成功？

  def create

    @account = User.find_by_id(params[:account_id])
    key = @account.access_code
    Stripe.api_key = key
    account_suid = @account.uid
    @order = Order.find(params[:order])
    charge = @order.amount * 100
    fee = @order.amount * 1
  
    token = params[:stripeToken]
    customer = Stripe::Customer.create(email: @order.email,source: token)
 
     Stripe::PaymentIntent.create({
       customer: customer,amount: (charge).to_i,confirm: true,currency: 'gbp',payment_method_types: ['card'],application_fee_amount: (fee).to_i,},{
       stripe_account: account_suid
     })
    options = {
      stripe_id: customer.id
    }

    options.merge!(
      card_last4: params[:user][:card_last4],card_exp_month: params[:user][:card_exp_month],card_exp_year: params[:user][:card_exp_year],card_type: params[:user][:card_brand]
    )

    OrderFiniJob.perform_now(@order)
    redirect_to session.delete(:return_to),notice: "Your order has been successful ??"
    
  end

解决方法

发生错误或付款被拒时，stripe会引发异常（some stripe erros）。 因此，您可以挽救错误并响应所需的内容，例如400

def create
  ...
  redirect_to ...

rescue Stripe::StripeError
  render status: :bad_request
end
