The id field in my database is des_id, how can I change it to des_id?

Route::post('Itest/LoadSuppliers', function (Request $request) { $request->validate([ 'destination_id' => 'required|exists:mysql.tbl_destinations,des_id', 'from' => 'required|numeric|min:0', 'to' => 'required|numeric|min:0', ]); $destination_id = Destination::where('des_id','=', $request->destination_id)->firstOrFail(); $from = $request->from; $to = $request->to; dispatch(new TestJob($destination_id, $from, $to)); return response()->json([ 'status' => true ]); });
