如何使用laravel中的嵌套關​​系列字段對查詢結果進行排序？

Question

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

Answer 1

添加到您的物業型號排序rentalunit收集

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

然後

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