QSqlTableModel doesn't delete the rows

[AlexxanderX]

I have this piece of code:

for (std::size_t i=0; i<m_rowsToDelete.size(); ++i)
    {
        qDebug() << m_rowsToDelete[i] << m_tableModelDB->removeRow(m_rowsToDelete[i]);
    }
 
    m_db.transaction();
    bool a = m_tableModelDB->submitAll();
    qDebug() << "submitAll() =>" << a;
    m_db.commit();

for (std::size_t i=0; i<m_rowsToDelete.size(); ++i)
    {
        qDebug() << m_rowsToDelete[i] << m_tableModelDB->removeRow(m_rowsToDelete[i]);
    }

    m_db.transaction();
    bool a = m_tableModelDB->submitAll();
    qDebug() << "submitAll() =>" << a;
    m_db.commit();

I get true everywhere but the rows are not deleted from database.
