Carrierwave large file optimization

Carrierwave documentation includes this tip for uploading large files. Inside your uploader, add these two methods (they say)

  def move_to_cache     true   end   def move_to_store     true   end

to make the uploads work more efficiently. This is true, it does work -- as long as you aren't trying to do anything with versions or other processing. If you do, then the upload will only ever work in a create method, not an update.

Can anyone suggest a way where I may be able to take advantage of the one-pass upload on create, but still manage to access the stored file as a file (the result of move_to_cache, I believe) when I need to?

Thanks in advance,
