我能够创建和订购并成功运行并保存它。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,用户可以上传自己的照片,该照片将在网站上展示。整个过程仍然可以正常工作,除非用户附上照片。发生这种情况时,它只是无法通过信用卡验证。取下附件,然后它再次正常工作。

订单.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

订单控制器.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,附上一张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它,但它是。感觉就像回形针中的错误。在与 activemerchant 进行交易时,有人在上传文件时遇到过类似的问题吗?这是一个相当简单的订单类型,有三个订阅选项。

甚至关于如何更好地测试并查看发生了什么的建议也会非常有帮助,这让我现在非常困惑。
