ruby-on-rails - 处理模型中的 Stripe 错误

Question

在模型中使用方法时，是否可以将 Stripe 错误消息呈现为通知。这是我现在的 Controller

def create
  @donation = @campaign.donations.create(donation_params)
    if @donation.save_with_payment
      redirect_to @campaign, notice: 'Card charged successfully.'
    else
      render :new
    end
end

我的方法是这样的

def save_with_payment
  customer = Stripe::Customer.create(
    :email => email,
    :card  => stripe_token
  )

  charge = Stripe::Charge.create(
    :customer    => customer.id,
    :amount      => donation_amount,
    :description => 'Rails Stripe customer',
    :currency    => 'usd'
 )
end

我从其他人的例子中注意到 Stripe 有一个

rescue Stripe::error
 rescue Stripe::InvalidRequestError => e

但我不确定如何获取这些错误，然后将它们放入通知中。

你可以这样做，假设 save_with_payment 是一个回调(我假设是 before_create 或 before_save)

def save_with_payment
  customer = Stripe::Customer.create(
    :email => email,
    :card  => stripe_token
  )

  charge = Stripe::Charge.create(
    :customer    => customer.id,
    :amount      => donation_amount,
    :description => 'Rails Stripe customer',
    :currency    => 'usd'
 )
rescue Stripe::error => e
   errors[:base] << "This donation is invalid because #{e}"
rescue Stripe::InvalidRequestError => e
   errors[:base] << "This donation is invalid because #{e}"
end

你可能想看看 stripe 是否有它创建的更具体的错误，如果有的话，你可以将错误添加到捐赠具有的特定属性上。例如(编造一个无效的电子邮件错误，因为捐赠看起来有一封电子邮件)

rescue Stripe::InvalidEmailError => e
  errors.add(:email, e)
end
