问题：控制器怎么写？

public function store(Request $request)
{
    $respondent= new Respondent;
    $respondent->name = $request->name;
    $respondent->email = $request->email;
    $respondent->save();

    $sport = new Sport;
    //接下来怎么写？

    return redirect()->action('RespondentController@index');
}

public function store(Request $request) { $params = $request->all(); $respondent= new Respondent; $respondent->name = $params['name']; $respondent->email = $params['email']; $respondent->save(); $respondent->sports()->attach($params['sportd_ids']); }

使用laravel的多对多关联模型插入方法。
获取受访者(respondents)的id：1）如果有登录，应该从session中获得；2）如果是即时创建的话，那创建就行了。说一下第二种方法
respondents与sports要建立多对多的关联关系。
