SQLite problem loading from file and display result in table

[unix7777]

What i want is to load .sqlite file and dimply query in table.
Unfortunately no table is displayed, just empty window.
Database file is in the project main folder.

QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
 
    //db.setDatabaseName(QApplication::applicationDirPath() + QDir::separator() + "faktura.sqlite");
    db.setDatabaseName("faktura.sqlite");
    db.open();
 
 
    QSqlQueryModel *model = new QSqlQueryModel;
 
        model->setQuery("SELECT customer_id,name, address FROM customers");
        model->setHeaderData(0, Qt::Horizontal, QObject::tr("Field 1"));
        model->setHeaderData(1, Qt::Horizontal, QObject::tr("Field 2"));
        model->setHeaderData(2, Qt::Horizontal, QObject::tr("Field 3"));
 
 
 
        QTableView *view = new QTableView;
        view->setModel(model);
        view->show();

QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");

    //db.setDatabaseName(QApplication::applicationDirPath() + QDir::separator() + "faktura.sqlite");
    db.setDatabaseName("faktura.sqlite");
    db.open();


    QSqlQueryModel *model = new QSqlQueryModel;

        model->setQuery("SELECT customer_id,name, address FROM customers");
        model->setHeaderData(0, Qt::Horizontal, QObject::tr("Field 1"));
        model->setHeaderData(1, Qt::Horizontal, QObject::tr("Field 2"));
        model->setHeaderData(2, Qt::Horizontal, QObject::tr("Field 3"));



        QTableView *view = new QTableView;
        view->setModel(model);
        view->show();

To copy to clipboard, switch view to plain text mode
