Rails 3序列化问题 [英] Rails 3 Serialization issue

问题描述

我有一个与ror 2.3.x兼容的应用程序。我在通过序列化升级到Rails 3时遇到了麻烦。

代码如下：

  class PaymentTransaction< ActiveRecord :: Base 
 serialize：response 
 end 
  

该响应应该包含ActiveMerchant :: Billing :: Response。使用rails 3出于某种原因将其另存为字符串。

  => ＃< PaymentTransaction ID：11，order_id：无，金额：nil，模式：nil，payment_profile_id：无，响应：＃< ActiveMerchant :: Billing :: Response：0x1051aec98>，created_at： 2010-11-07 04:06:03，updated_at： 2010-11-07 04:24:58，结果：待处理，收款人：nil，login_id：nil，transaction_key：nil> 
  

我在其他任何有关升级的博客中都没有关于序列化的记录。有什么想法吗？

解决方案

rails 3发生了很小的变化，其效果如下： https://github.com/rails/rails/commit/c1d73270717f30498f8f4d55d6695509107c2834

I have an application that was working fine with ror 2.3.x. I am having trouble upgrading to Rails 3 with serialization.

The code looks like this

class PaymentTransaction < ActiveRecord::Base
  serialize :response
end

The response is supposed to contain the ActiveMerchant::Billing::Response. With rails 3 for some reason its being save as string.

=> #<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>

I didn't any notes on serialization in any other blogs talking about upgrade. Any thoughts?

解决方案

There was a small change in rails 3 which have an effect: https://github.com/rails/rails/commit/c1d73270717f30498f8f4d55d6695509107c2834

There are two good blog posts about serialization here:
