That doesn't work... it gives me the relationship error...

DBIx::Class::ResultSet::search(): No such relationship user


This does work... although it doesn't look that pretty so I'm going to
assume its still not the easiest way...

    my $rs = $dbh->resultset('User')->search({ 'sessionid' => '123456'
} ,{ prefetch => 'user_session' });
    my $user = $rs->next;

    print "u " . $user->username . "\n";

    my $session = $user->user_session->next;

    print "s ". $session->sessionid . "\n";
