如何使用carrierwave

Class Profile 

    mount_uploader :avatar, MyUploader 
    mount_uploader :cover_page, MyUploader 
    mount_uploader :fav_cat_pic, MyUploader 

end

我怎样才能提取“方法”获得了一类装载器（即avatar，cover_page和fav_cat_pic）绑定到MyUploader在运行时？

从哪儿CarrierWave::Uploader::Base

使用uploaders方法MyUploader继承

例如 Profile.uploaders
