Well, If I well understood the problem,
I think you can have something like: 0.py with a connection to a
shared database
database_to_use = request.application
db = DAL(shared_db)
db.define_table(Field('db_name', 'string'))
row =
db().select(db.shared_db.db_name==database_to_use).select().first()
if not row:
db.shared_db.insert(db_name=database_to_use)
Now in your db.py
you can have another connection to retrieve db name and use it
and guess what if you forgot and ran your application without creating
the intended database manually
db.py will fail
