    return $this->doFormat($query, $format, $limit);
}

public function insert(Request $request): Response

    if ($request->method() === 'POST') {

    {
        [$where, $format, $limit, $field, $order] = $this->selectInput($request);
        if (!empty($where['name']) && is_string($where['name'])) {
            $where['name'] = ['like', "%{$where['name']}%"];
        }
        $query = $this->doSelect($where, $field, $order);
        $query = $query->with(['user' => function($q){
            $q->select('nickname','id');
        }]);
        return $this->doFormat($query, $format, $limit);
