Railsのcarrierwaveでアップロード済みの画像をコピーする方法

Posted at 2014-04-01

すでに、アップロード済みのorg_imageのavatarをnew_imageのavatarにコピーする場合。

org_image.rb

class OrgImage < ActiveRecord::Base
    mount_uploader :avatar, ImageUploader

    xxxxx
    xxxxx

end

new_image.rb

class NewImage < ActiveRecord::Base
    mount_uploader :avatar, ImageUploader

    xxxxx
    xxxxx

end

controller.rb



def image_copy
    org_image = OrgImage.find(id)
    new_image = NewImage.new
    new_image.avatar = org_image.avatar.file
    new_image.save
end
