problem with QSqlTableModel and unique_ptr ! QTableView has The data but show Nothing

Proton Phoenix

Hi ~~ I Have A problem Using unique_ptr

std::unique_ptr<QSqlTableModel> freshModel(new QSqlTableModel(ui->clientstableview_2));
    freshModel->setTable("clients");
    freshModel->select();

    if (!freshModel->select()) {
        qDebug() << "Error in select:" << freshModel->lastError().text();
    } else {
        qDebug() << "working ~ row count="<<freshModel->rowCount();
    }
    ui->clientstableview_2->setModel(freshModel.get());
    qDebug()<<"HeaderData 0 ="<<ui->clientstableview_2->model()->headerData(0,Qt::Horizontal).toString();
     // tableView has the data correctly but the TableView Show Nothing ... ~!

is there any solution for that?

No, the model is not alive after the unique pointer destroys it...

Don't use a shared pointer or make sure it is alive as long as the tableview.
