Thanks again for your support. I'm afraid to disturb you again, I promise that is the last time (I hope ;-))) Only two things.
1) during the definition of the plan table I receive the error: non-keyword arg after keyword arg To correct it I have to put primary_key=True after the ForeignKey definition, is it correct? The table description after it creation is: year | integer | not null default nextval('plan_year_seq'::regclass) month | integer | not null default nextval('plan_month_seq'::regclass) day | integer | not null default nextval('plan_day_seq'::regclass) instrument_id | integer | not null data | text | 2) I'm trying to put some data on the db. But I don't understand how to put a new instrument in the plain table. If I do: i=session.query(Instrument).get(1) p=PlanEntry() p.day=1 p.year=2006 p.month=9 p.instrument.append(i) or p.instrument.append(Instrument(i)) I raise an exception: 'str' object has no attribute 'append' (i.name and i.instrument_id exists).
