ruby-on-rails - 在 Rails 3 中猴子补丁 ActiveRecord::Base::ConnectionSpecification

Question

我正在尝试ActiveRecord::Base::ConnectionSpecification::Resolver在 Rails 3 中使用猴子补丁作为未解决错误的解决方法。

最干净的方法是什么？我将把这段代码放在哪里，以便被 Rails 拾取？谢谢！

创建文件config/initializers/active_record_extension.rb

module ActiveRecordExtension    
  extend ActiveSupport::Concern    
  # add your instance methods here
  def foo
  end
end    
ActiveRecord::Base::ConnectionSpecification::Resolver.send(:include,ActiveRecordExtension)
