You don't necessarily need a class. The point is just that you need to pass in the db instance, either via an __init__ method of a class, or simply as an argument to your function. In your case: def number_of_records(db, table): And when you call that function, pass in your db object as the first argument. Another option is to add the db object to "current" -- for example, in the db.py model file: from gluon import current current.db = db Then when you import current in your module, you can refer to current.db.
