如何在laravel中使用嵌套关系列字段对查询结果进行排序？

Question

$props = Property::with(['rentalUnit','rentalUnit.floor'])->get()->toArray();

我想用楼层表字段floor_name字段对rentalunit集合进行排序

任何帮助，将不胜感激

将此添加到您的媒体资源模型

public function rentalUnitOrderByFloorName() 
{
    return $this->rentalUnit()->select('rental_units.*', 'floors.name')->leftJoin('floors', 'floors.rental_unit_id', '=', 'rental_units.id')->orderBy('floors.name');
}

然后

$props = Property::with(['rentalUnitOrderByFloorName','rentalUnitOrderByFloorName.floor'])->get()->toArray();
