I chose to consolidate these two classes, since inevitably they always went in pairs (e.g. SqliteDatabase/SqliteAdapter). The database class now encapsulates all this functionality. 1.3.5 How the SQL “connect” step, rather than some arbitrary time later when a query is executed. >>> database = SqliteDatabase(’stats.db’) >>> database.connect() To use this database with your models, specify it in an inner use multiple databases (provided that you don’t try and mix models from each): >>> custom_db = SqliteDatabase(’custom.db’) >>> class CustomModel(Model): ... whatev = CharField() ... ... class Meta: .
