我使用雄辩的php作为orm，并为我的web应用程序实现查询生成器。
通常，当代码看起来像这样时，它会工作。

$builder = Area::query()->limit(30);

if ($subDistrictCode = $request->getParam('sub_district_code')) {
    $builder->where('sub_district_code', $subDistrictCode);
}

if ($districtCode = $request->getParam('district_code')) {
    $builder->where('district_code', $districtCode);
}

$areasCount = $builder->count();

if ($limit = $request->getParam('length')) {
    $builder->limit($limit);
}

if ($offset = $request->getParam('start')) {
    $builder->offset($offset);
}

$areas = $builder->orderBy('province','ASC')->get();

但当我使用对象的属性时，我得到了以下错误：
调用未定义的方法erdkk\models\areas:：getidattribute（）
代码如下所示。

$builder = Area::query()->limit(30);

if ($subDistrictCode = $request->getParam('sub_district_code')) {
    $builder->where('sub_district_code', $subDistrictCode['id']);
}

if ($districtCode = $request->getParam('district_code')) {
    $builder->where('district_code', $districtCode);
}

$areasCount = $builder->count();

if ($limit = $request->getParam('length')) {
    $builder->limit($limit);
}

if ($offset = $request->getParam('start')) {
    $builder->offset($offset);
}

$areas = $builder->orderBy('province','ASC')->get();
