Paperclip renaming files after they're saved

Question

How do I rename a file after is has been uploaded and saved? My problem is that I need to parse information about the files automatically in order to come up with the file

To add to @Voyta's answer, if you're using S3 with paperclip:

(record.image.styles.keys+[:original]).each do |style|
  AWS::S3::S3Object.move_to record.image.path(style), new_file_path, record.image.bucket_name
end

record.update_attribute(:image_file_name, new_file_name)
