def update_show():
    """Show add and edit handler.

    Either displays a template allowing the user to edit or add a show, or attempts
    to edit or add the show, depending on if the method is GET or POST. The function
    is aborted with a ``404`` message to hide the page if the user is not authenticated.

    GET method:
        Requires ``id`` to be passed as the ID of the show in a query string. If
        the show can't be found, abort with a ``404`` message. Otherwise, lookup
        the show in the db, as well as sub groups subtitling the show and the selected
        sub group if there is one, and some fanart to render on the background.

    POST method:
        Requires ``id``, ``beid``, and ``subgroup`` to be passed as form parameters.
        ``id`` is the DB id of the show, ``beid`` is the backend ID of the show, and
        ``subgroup`` is the subgroup the user has selected. This will attempt to add
        the show to the backend.

    Returns:
        A rendered template with a form on the GET method.
        A redirect to the home as a refresh on the POST method.
