Dear all,
I've a strange problem with session.flush() that I'm not able to
understand why. I've the following tables
users=Table('users', metadata,
Column('user_id', Integer, primary_key=True),
Column('firstname', String),
Column('lastname', String),
Column('login', String),
Column('uid', Integer),
Column('gid', Integer),
Column('password', String),
Column('email', String),
Column('institute', String),
Column('nationality', String),
Column('home_directory', String),
Column('category', String(1)))
calculation=Table('calculations', metadata,
Column('calculation_id', Integer, primary_key=True),
Column('user_id', Integer, ForeignKey('users.user_id'),
primary_key=True),
Column('program', String),
Column('job', String),
Column('workdir', String),
Column('start_date', DateTime),
Column('protein', String),
Column('status', String(1)))
So, I create the engine and so on.
engine=create_engine('postgres://[EMAIL PROTECTED]/db')
metadata=BoundMetaData(engine)
session=create_session()
users=Table('users', metadata, autoload=True)
calculations=Table('calculation', metadata, autoload=True)
class Users(object): pass
class Calculations(object): pass
mapper(Users, users)
mapper(Calculations, calculations, properties={'user':
relation(Users)})
u=session.query(Users).get_by(login='rossi')
c=Calculations()
c.job='1234'
c.user_id=u
c.start_date=time.asctime()
c.program='cara'
c.workdir='/home/morelli'
c.protein='test'
c.status='R'
session.save(c)
session.flush()
SQLError: (ProgrammingError) can't adapt 'INSERT INTO calculations
(calculation_id, user_id, job, workdir, start_date, protein, status,
program) VALUES (%(calculation_id)s, %(user_id)s, %(job)s, %(workdir)s,
%(start_date)s, %(protein)s, %(status)s, %(program)s)' {'status': 'R',
'workdir': '/home/morelli', 'user_id': <__main__.Users object at
0xb75d55cc>, 'calculation_id': 11L, 'job': '1234', 'program': 'cara',
'protein': 'test', 'start_date': 'Tue Nov 28 09:59:07 2006'}
If I do the same thing by hand under psql, it's works fine.
Where is the problem?
Thanks
