Rails 3序列化问题

Question

我有一个适用于ror 2.3.x的应用程序.我无法使用序列化升级到Rails 3.

代码看起来像这样

class PaymentTransaction < ActiveRecord::Base
  serialize :response
end

响应应该包含ActiveMerchant :: Billing :: Response.由于某种原因,使用rails 3将其保存为字符串.

=> #<PaymentTransaction id: 11, order_id: nil, amount: nil, mode: nil, payment_profile_id: nil, response: "#<ActiveMerchant::Billing::Response:0x1051aec98>", created_at: "2010-11-07 04:06:03", updated_at: "2010-11-07 04:24:58", result: "pending", payee: nil, login_id: nil, transaction_key: nil>

关于升级的任何其他博客我没有关于序列化的任何注释.有什么想法吗？

Rails 3 中有一个小的变化，产生了影响：https://github.com/rails/rails/commit/c1d73270717f30498f8f4d55d6695509107c2834
