Question

MODX

Changes are not saved when modifying MODX objects

$state = $modx->getObject('StorageState', array('slot' => $move->slot_a->name, 'good_uuid' => $good->uuid));
      if($state) {
        $state_A_New_Count = $state->good_count - $move->count;
        if($state_A_New_Count >= 0) {
          $state->set('good_count', $state_A_New_Count);
        } else {
          $state->set('good_count', $state_A_New_Count);
        }
        
        $state->save();
      } else {
        // Источник не определён, Сохраняем дефицит
        $state = $modx->newObject('StorageState');
        $state->fromArray([
            'slot' => $move->slot_a->name,
            'good_uuid' => $good->uuid,
            'good_count' => -$move->count
        ]);
        $state->save();
    
      }
