def update_attributes(attributes)
  # Sometimes we have to do initial preparing of attributes, before sending them to updating.
  # For example, if we use select_datetime from Rails, it creates many fields in params, so the resulting
  # params may look like:
  #
  #    {'foo' => 'bar', 'date(1i)' => '2000', 'date(2i)' => '10', 'date(3i)' => '30'}
  #
  # Of course we have to modify it to put everything into the same key, like:
  #
  #    {'foo' => 'bar', 'date' => '2000-10-30'}
  #
  # or something like that. So, if your attribute type requires such transformations, please specify
  # .convert_attributes method in it.
