PyQt5: specifying QSqlTableModel

[Rich Shepard]

Debugging a module to display a QTableView of a small database table I get
this error:

File "activitytypes.py", line 27, in __init__
     self.model = qts.QSqlTableModel(dbs.db)
AttributeError: type object 'DBSetup' has no attribute 'db'

My two PyQt5 books and my web searches for using QSql haven't taught me how
to specify the database name in modules that import and use the database
setup module.

Both datasource.py and activitytypes.py are attached and I need to learn how
to use QSql in my database desktop applications. Help's definitely needed
here.
