ActiveMerchant不驗證信用卡無效

Question

我有ActiveMerchant信用卡驗證一個問題，在我的Rails 2.3.2應用程序。（ActiveMerchant 1.4.1）

我跟着railscast＃145事件代碼完全相同。

當我驗證的信用卡一樣無效數據我的問題是：FIRST_NAME，：姓氏爲空，ActiveMerchant不給驗證錯誤

我在我的腳本/控制檯試過這種

credit_card = ActiveMerchant::Billing::CreditCard.new(:number => "",:first_name => "") 
credit_card.errors.full_messages #=> [] 
credit_card.errors #=> {} 

我payment.rb包含

validate_on_create :validate_card 

private 

def validate_card 
    unless credit_card.valid? 
    credit_card.errors.full_messages.each do |message| 
     errors.add_to_base message 
    end 
    end 
end 

def credit_card 
    @credit_card = ActiveMerchant::Billing::CreditCard.new(
    :number    => card_number, 
    :month    => card_expires_on.month, 
    :year    => card_expires_on.year, 
    :first_name   => first_name, 
    :last_name   => last_name, 
    :verification_value => cvv_number, 
    :type    => card_type 
    ) 
end 

不會添加信用卡錯誤@payment我在控制器中創建對象＃創建 請告訴我，我做了錯誤

請添加一個||在你的信用卡功能

def credit_card 
    @credit_card ||= ActiveMerchant::Billing::CreditCard.new(
    :number    => card_number, 
    :month    => card_expires_on.month, 
    :year    => card_expires_on.year, 
    :first_name   => first_name, 
    :last_name   => last_name, 
    :verification_value => cvv_number, 
    :type    => card_type 
    ) 
end
