Derek, thanks for your suggestion. Which is the preferred way to reopen the connection and define the tables?
My db.py contains db = DAL(connection_string, options...) db.define_table('table1', Field('f1' ...), Field('f2'...)) db.define_table(...) db.define_table(...) ... So ideally I wouldn't have to repeat this code in my script. Is it best I break out the DAL/define_tables calls into a file that I import both in my db.py and in my script.py?
