QTableView, QSqlTableModel - data disappears

I'm using PyQt. I want to put the rows from my database to table_view1 (QTableView).
The problem is I can't see any rows in table_view1 - the data disappers (some refresh?)
look a at lines 20-22.

Code:

---

model = QtSql.QSqlTableModel()
 
        model.setTable("klienci")
 
        model.setEditStrategy(QtSql.QSqlTableModel.OnManualSubmit)
 
 
        model.setHeaderData(0, QtCore.Qt.Horizontal, 
                        QtCore.QVariant(QtCore.QObject.tr(model, "ID")))
        model.setHeaderData(1, QtCore.Qt.Horizontal, 
                        QtCore.QVariant(QtCore.QObject.tr(model, "First name")))
        model.setHeaderData(2, QtCore.Qt.Horizontal, 
                        QtCore.QVariant(QtCore.QObject.tr(model, "Last name")))
 
 
        model.select()
        self.ui.table_view1.setModel(model)
        self.ui.table_view1.setItemDelegate(QtSql.QSqlRelationalDelegate(self.ui.table_view1))
 
        #that's for testing - when I raise error, I can see the rows from database
        #if line below is commented, the data in table_view1 disappers.
        #self.ui.table_view1.foo()

What I'm doing wrong? Any suggestions?

Hi,

two ideas:

1. check for errors: model->lastError().text()
2. Remove the line with the Delegate

edit:
no idea about python, but try to use the model on the heap: model = new QSqlTableModel ...
