Rails - Feb 2009 - cloning an already uploaded image using attachment_fu

Hi,

I have an Image model that is attached to a item. The image was uploaded
through attachment_fu. Now, I want to reuse the same image for a new
item. I tried several tips found online. For example in

http://danieloshea.com/articles/254-cloning-images


# Create a clone of an image and it''s thumbnails.
      def create_clone
        c = self.clone
        self.thumbnails.each do |thumb|
            n = thumb.clone
            n.temp_path = thumb.create_temp_file
            n.save_to_storage
            c.thumbnails<<n
         end
       c.temp_path = self.create_temp_file
       c.save_to_storage
       c.save
       return c
      end

But the end result is an exception at

 n.temp_path = thumb.create_temp_file

saying that undefined method temp_path (probably for the thumbnail n)???

I spent my whole weekend on it and I am pulling my hair off to solve it!

Any help?

Thanks,

class Image < ActiveRecord::Base

  #you attachment fu config

  def clone
    cloned = super
    cloned.filename = "#{rand(1000)}_#{self.filename}"
    cloned.temp_data = File.read( self.full_filename )
    cloned
  end

end


#code

cloned_image = some_image.clone
cloned_image.save! #saving the image will also create the thumbnails
