Has anyone gotten something like this to work?
https://doc.qt.io/qtforpython/overviews/qtsql-sqlwidgetmapper-example.html#sql-widget-mapper-example
Tried but not having any luck and their examples are not in python just the same snippets from C++ which while is kinda helpful not actually useful as it does not have full working example can just translate and make work.
All of the fields work and show values except the qcomboboxes for “SSH Key Name”, “SSH Config Name”, and Group(SSH Group Name) .
self.ssh_key_name = QComboBox()
self.ssh_config_name = QComboBox()
self.ssh_group = QComboBox()

I also found this link but its kinda hard to follow as full code snippet is not readable.
