Issue with QSqlRelationalTableModel updating Sqlite views

[swivelhead]

I am attempting to use a "subclassed" QSqlRelationalTableModel object that I wish to use to update a Sqlite view (which passes an update to a table via an "instead-of" trigger.)

I have the following code:

SqlRelationalTableModel.hpp:
@
#ifndef SQLRELATIONALTABLEMODEL_HPP
#define SQLRELATIONALTABLEMODEL_HPP

#include <QModelIndex>
#include <QSqlRelationalTableModel>

class SqlRelationalTableModel : public QSqlRelationalTableModel {
Q_OBJECT
public:
SqlRelationalTableModel(
QObject *parent = (QObject *)0
, QSqlDatabase db = QSqlDatabase());

QString selectStatement() const;
bool insertRow(int row, const QModelIndex &parent = QModelIndex());
bool removeRow(int row, const QModelIndex &parent = QModelIndex());

private slots:
bool submit();

signals:
void dataSubmitted();
};

#endif // SQLRELATIONALTABLEMODEL_HPP
@

SqlRelationalTableModel.cpp:
@
#include <QtGui>
#include <QtSql>
#include <QDebug>
#include "SqlRelationalTableModel.hpp"

SqlRelationalTableModel::SqlRelationalTableModel(
QObject *parent, QSqlDatabase db)
: QSqlRelationalTableModel(parent, db) {
// intentionally empty function
}

QString SqlRelationalTableModel::selectStatement() const {
return QSqlRelationalTableModel::selectStatement();
}

bool SqlRelationalTableModel::insertRow(int row, const QModelIndex &parent) {
bool isRunningOkay = true;

isRunningOkay = QSqlRelationalTableModel::insertRow(row, parent);

emit dataSubmitted();

return isRunningOkay;
}

bool SqlRelationalTableModel::removeRow(int row, const QModelIndex &parent) {
bool isRunningOkay = true;

isRunningOkay = QSqlRelationalTableModel::removeRow(row, parent);

emit dataSubmitted();

return isRunningOkay;
}

bool SqlRelationalTableModel::submit() {
bool isRunningOkay = QSqlRelationalTableModel::submit();

emit dataSubmitted();

return isRunningOkay;
}
@

ItemForm.cpp
@
inItemModel = new SqlRelationalTableModel(this);
inItemModel->setTable("inItemMapView");
inItemModel->setRelation(
InItemMapView_CategoryId
// , QSqlRelation("inCategoryMapView", "categoryId", "categoryName"));
, QSqlRelation("inCategoryMapView", "categoryId", "categoryId"));
inItemModel->setSort(InItemMapView_ItemName, Qt::AscendingOrder);
inItemModel->setHeaderData(InItemMapView_ItemName, Qt::Horizontal, tr("Item"));
inItemModel->setHeaderData(InItemMapView_CategoryId, Qt::Horizontal, tr("Category"));
inItemModel->setEditStrategy(QSqlTableModel::OnRowChange);
inItemModel->select();

inItemView = new TableView(this);
inItemView->setModel(inItemModel);
inItemView->setItemDelegate(new QSqlRelationalDelegate(inItemView));
@

The above does allow an update when editing the view, but it shows the categoryId which is an ugly UUID instead of the categoryName. When I comment that out and instead set the relation to categoryName, it does not keep my edits. Nor does it let me delete. Inserts work though, for some reason.
