如何使用carrierwave

Class Profile 

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

end

我怎樣才能提取「方法」獲得了一類裝載器（即avatar，cover_page和fav_cat_pic）綁定到MyUploader在運行時？

從哪兒CarrierWave::Uploader::Base

使用uploaders方法MyUploader繼承

例如 Profile.uploaders
