从其他类访问Railtie初始化程序中的变量

Question

I have a gem which has the following Railtie class. I am trying to access my_config variable from outside, ie another ruby class in the same gem. How can I access it?

module myModule
    module Rails
      class Railtie < ::Rails::Railtie

        initializer 'load_config' do
          my_config = "random config here"
          puts my_config
        end
      end
    end
  end
end

也许您可以使用instance_variable_get ：

myModule::Rails::Railtie.new.instance_variable_get(:@my_config)
