i'm trying to save a new tvshow and it's episodes into the database with the following code but in the database show_id column is 0

//
$show = New Show();
$show->fill( $showInfo );
$show->save();

foreach( $episodes as $episodeInfo )	{
    //
    $showEpisode = New ShowEpisode();
    $showEpisode->fill($episodeInfo);

    //
    $show->episodes()->save( $showEpisode );
}

i have also tried associating the show using the following code

//
$showEpisode = New ShowEpisode();
$showEpisode->fill($episode);
$showEpisode->show()->associate($show);
$showEpisode->save();

it seems that you cannot use a newly created model for association, but when using the below code to load the show model, the association works and in the database show_id is the correct value

$show = Show::find($showId);

is this how it is supposed to be? and should i be reloading the show from the database after inserting it ?
