I didn't get it to work.

http://qt-project.org/doc/qt-5/QObject.html
Here is also mentioned to use QObject subclasses in lists only with pointers.

Code copied from database.cpp line 232
@
template <class Type>
Type Database<Type>::fillUpType(const QSqlRecord &record) const
{
Type item;

QStringList list;
Utils::extractObjectProperties(item.metaObject(), &list, false, DB_PREFIX);
foreach (const QString &property, list) {
item.setProperty(qPrintable(property), record.value(QString(property).remove(DB_PREFIX)));
}

return item;
}

template <class Type>
QList<Type> Database<Type>::retrieveTypes(Filter arg) const
{
QList<Type> wineList;

if (!m_wineModel) {
qCritical() << "Unable to insert a wine";
goto exit;
}

if (arg == OrderByAgeDesc) {
m_wineModel->setSort(4, Qt::DescendingOrder);
}
m_wineModel->select();

for (int i = 0; i < m_wineModel->rowCount(); ++i) {
const QSqlRecord record = m_wineModel->record(i);
wineList << fillUpType(record);
}

exit:
return wineList;
}
