Ruby on rails 如何在更新的rails3.1应用程序中保留旧的activerecord 2.3 associations.rb
我有一些继承的代码： 我有一个Rails 2.3应用程序，我已经更新到Rails 3.1 主要问题： 在我继承的代码中，有一个文件使用了这些不推荐使用的方法Ruby on rails 如何在更新的rails3.1应用程序中保留旧的activerecord 2.3 associations.rb,ruby-on-rails,ruby,activerecord,Ruby On Rails,Ruby,Activerecord,我有一些继承的代码： 我有一个Rails 2.3应用程序，我已经更新到Rails 3.1 主要问题： 在我继承的代码中，有一个文件使用了这些不推荐使用的方法 alias_method_chain :association_join, :fix 及 关联联接和构造联接已被弃用，我不知道应该用什么替换它们。有人知道我可以把它们重构成什么吗？我似乎在网上找不到任何信息。或者有没有一个gem可以解决这个弃用问题 在应用程序内部有一个rails 2.3“修复”文件用于关联，现在在rails 3.1更新下
