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).
