How to use order by query both with current table column and relationship table column in laravel?

问题

i am trying to fetch record with order by query but situation is this that i have to use order by both on current table column and relationship table column in laravel . I tried this

 $consignments = Consignment::where('delivery_run_id', $id)->whereIn('status', [
            'In Warehouse',
            'With On Forwarder',
            'In Transit (Warehouse->Delivery)',
            'Awaiting Pickup'
        ])->with(['consignment_run_sheet' => function ($query) {
            $query->orderBy('run_sheet_id');
        }])->orderBy('delivery_date', 'DESC')->get();
        $deliveryRuns = DeliveryRun::all();

How I can achieve it?

回答1:

it will order just the relation items in this way. solution is use subquery or joins. useing Subquery is like this if assume the modal for consignment_run_sheet relation is ConsignmentRunSheet and the relation is belongsTo:

 $consignments = Consignment::where('delivery_run_id', $id)->whereIn('status', [
            'In Warehouse',
            'With On Forwarder',
            'In Transit (Warehouse->Delivery)',
            'Awaiting Pickup'
        ])->with('consignment_run_sheet')
        ->orderBy(ConsignmentRunSheet::select('delivery_date')
                  ->whereColumn('consignments.id', 'consignment_run_sheet.consignment_id'), 'DESC')
        ->get()
