def path(options=nil)
  return attached_file.path if options.nil?
  process(options).path
end

#public_path(options = {}, base = 'public') ⇒ Object

Simple helper, same as path except returns the directory from …/public/ on, i.e. for showing images in your views.

@asset.path        => /var/www/site/public/assets/000/000/001/313/milton.jpg
@asset.public_path => /assets/000/000/001/313/milton.jpg

Can send a different base path than public if you want to give the path from that base on, useful if you change your root path to somewhere else.
