Question

我能够创建并订购并成功运行并保存。我正在使用订单模型和order_transaction模型。我添加了一个字段，以便在填写订单和订阅时，用户可以上传将在网站上显示的自己的照片。除了用户附加照片的情况外，整个过程仍然可以正常工作。当发生这种情况时，它只是未通过信用卡验证。取下附件，然后再次正常工作。

order.rb

class Order < ActiveRecord::Base

  has_many :transactions, :class_name => "OrderTransaction"

  attr_accessor :card_number, :card_verification, :card_expires_on, :response
  after_create :log_transaction

  attr_accessible :first_name,
                  :last_name,
                  :address_one,
                  :address_two,
                  :city,
                  :state,
                  :zip,
                  :country,
                  :email,
                  :verify_email,
                  :term,
                  :shirt_color,
                  :shirt_size,
                  :card_type,
                  :card_number,
                  :card_verification,
                  :transactions_attributes,
                  :card_expires_on_month,
                  :card_expires_on_year,
                  :photo


  has_attached_file :photo,
    :styles => { :medium => "320x320>", :thumb => "100x100#" }
  validates :first_name, :last_name, :address_one, :city, :state, :zip, :country, :presence =    > true
  validate :validate_card, :on => :create
  validate :require_shirt_size, :on => :create



  def purchase
    self.response = GATEWAY.purchase(price_in_cents, credit_card)
    errors.add(:base, response.message) unless self.response.success?
    self.response.success?
  end

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

  def price_in_cents
    total = 0

    if term == '1'
      total = 2000
    elsif term == '2'
      total = 3500
    elsif term == '3'
      total = 4500
    end
    unless shirt_color == 'none'
      total += 1599
    end

    total
  end

  def require_shirt_size
    unless shirt_color == 'none'
      if shirt_size == ''
        errors.add(:base, "Shirt Size required if ordering a shirt.")
      end
    end
  end

  private
    def log_transaction
      self.transactions.create!(:action => "purchase", :amount => price_in_cents, :response =    > self.response)
    end

    def validate_card

      unless credit_card.valid?
        credit_card.errors.full_messages.each do |message|
          errors.add(:base, message)
        end
      end
    end
end

order_transaction.rb

class OrderTransaction < ActiveRecord::Base

  attr_accessible :action, :amount, :response

  belongs_to :order
  serialize :params

  def response=(response)
    self.success       = response.success?
    self.authorization = response.authorization
    self.message       = response.message
    self.params        = response.params
  rescue ActiveMerchant::ActiveMerchantError => e
    self.success       = false
    self.authorization = nil
    self.message       = e.message
    self.params        = {}
  end
end

orders_controller.rb

def create
  @order = Order.new(params[:order])
  if @order.valid? && @order.purchase
    render :success and return
  else
    render :action => 'new'
  end
end

好像不知何故，附上照片会导致它失去传递信用卡数据的能力。我不确定它在哪里丢失，但确实如此。感觉就像回形针中的一个错误。在与activemerchant进行交易时，任何人都有与上传文件类似的问题？这是一个相当简单的订单类型，有三种订阅选项。

即使是关于如何更好地测试和查看正在发生的事情的建议也会非常有帮助，现在让我感到非常困难。

当订单中有回形针附件时，ActiveMerchant付款/ CC失败
