Hello Massimo, thank you for your fast reply!
Honestly I don't think that this is related to my problem since I only tried to demonstrate my problem with this example. If I define a table in a model, I should be able to access this table without any further configuration, right? So when I do the two db.define_table()-statements (as shown in my first post), I should be able to access the tables in a controller via db.album or db.track respectively. Unfortunately this is not the case and results in a KeyError. When I do db.tables in a controller, only the auth_*-tables are listed. Is there any possibility to see, if web2py fails while initializing the db-object? Setting the debug-level to 0 seems not the help since it does not list errors concerning the database.
