How to update/rename a carrierwave uploaded file?

Question

I cant figure out how to update/rename a file uploaded/managed with Carrierwave-mongoid in rails 3.2.6. I want to rename the file in the db as well as on the filesystem.

I did this with this way:

  def filename
    if !cached? && file.present?
      new_filename = 'foobar'
      new_path = File.join(File.dirname(file.path), new_filename)
      file.move_to(new_path)
      recreate_versions!
      new_filename
    else
      super
    end
  end

I think this is only right way to rename file.
