Question

I want to sort rentalunit collection with field of floor table field floor_name

Any help would be appreciated

Answer 1

Add this to your Property model

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

Then

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