    if (Model::loadMultiple([$person], $post) && Model::validateMultiple([$person])) {
        $team->load($post['Team']);
        foreach($post['Person'] as $person):
            $person->load($person);
            $person->team_id = $team->id;
            $person->save();
        endforeach;
        $team->save();
        return $this->redirect(['index']);
