php - 当使用对象的属性作为 where 语句的输入时，雄辩的查询构建器得到“BadMethodCallException”

Question

我使用 Eloquent PHP 作为 ORM 并为我的 Web 应用程序实现查询构建器。

通常，当代码看起来像这样时，它就可以工作。

$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();

但是当我使用对象的属性时，我得到了这个错误：

调用未定义的方法 Erdkk\Models\Areas::getIdAttribute()

代码看起来像这样。

$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();
