How to make sure images uploaded with paperclip have unique names?

I am using paperclip to save images. I have created an image model to save them to my public director

class Image < ActiveRecord::Base
  has_attached_file :file,
                    :url => "assets/projects_description_images/:style/:basename.:extension",
                    :path => ":rails_root/public/assets/projects_description_images/:style/:basename.:extension"


  validates_attachment :file,
                       :presence => true,
                       content_type: {content_type: ["image/jpg", "image/jpeg", "image/png", "image/gif"]},
                       :size => {:in => 0..50.megabytes}
end

However if I add I make an image with the name "main.jpg" and then create another with the name "main.jpg" when displaying the one that was created first it shows up with the second one. I will have no way of knowing the exact name that will be used but I can be certain that there will be duplicates. It would be great if I could have the file name be saved as something like

main_(unique_string).jpg

Any clue how to do this?

The answer provided by Andrey Turkin ( trevorturk.com/2009/03/22/randomize-filename-in-paperclip)solved my problem. One thing to note is that with rails 4.2 I had to change ActiveSupport::SecureRandom.hex(16) to just

SecureRandom.hex(16)
