        RawStockAction, StockAction,
        SyncTask,
)
SyncTask.objects.create(
        source=ContentType.objects.get_for_model(RawStockAction),
        target=ContentType.objects.get_for_model(StockAction),
        sync_method="sync_model.utils.sync_raw_stock_action",
        batch_size=2,
        order_by=["update_datetime", "-sender"],
        filter_by={
