In my experience it's better to move slightly more things into dispatcher:

on '/edit_post/*' => run {
    # * - also captures so you can do the following and don't need before rule:
    my $id = $1;

    # load right in dispatcher
    my $post = Jifty->app_class('Model::Post');
    $post->load( $id );

    # "404: not found" if not found
    abort(404) unless $post->id;

    # store object instead of id
    set post => $post;

    show '/edit_post' ;
};

I hope once you implement this and learn new tricks, you send us
patches for documentation to make things clearer for other newbies :)
