Rails 3中的Monkeypatching ActiveRecord::Base::ConnectionSpecification

Question

我正在尝试在Rails3中为ActiveRecord::Base::ConnectionSpecification::Resolver打补丁，作为一个未解决的bug的变通方法。

做这件事最干净的方法是什么?我应该把这段代码放在哪里，这样它就会被Rails拾取？谢谢!

Answer 1

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)
