處理模型中的條紋錯誤

Question

在模型中使用方法時，是否可以呈現條紋錯誤消息作爲註釋。這是我目前

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 

控制器和我的方法是，像這樣

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 

我從其他人注意到exmaples這條具有

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

但是我不知道如何抓住這些錯誤，然後把它們放在通知內

任何幫助讚賞謝謝

你可以做到這一點，假設save_with_payment是

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 

你可能想看看是否有條紋它創建不過更具體的錯誤回調（before_create或before_save我會承擔），如果是的話，你可以添加對捐贈具有的特定屬性的錯誤。例如（彌補無效的電子郵件錯誤，因爲捐款有一個電子郵件的外觀）

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