Nullable foreign keys in QTableView

[Banjo]

Hello

I have a QSqlRelationalTableModel which is viewed using a QTableView and QSqlRelationalDelegate to give comboboxes for foreign key fields.

My question is how do I handle nullable foreign keys? If foreign key is null it is not being displayed in the QTableView and there seems to be no way of having a null value in a combo box.

Thanks in advance

Hello
Is anyone able to help me??

I have no idea if it really works, but perhaps you could insert corresponding NULL values to those relational tables..

Thanks for that. I had hoped to avoid inserting rows like that but I will give it a go
