Hi all,
I need to insert a new row and get back the last inserted id,
I have some difficulty using the flush(), then I'm trying with
commit() but
I can't understand how commit() works in 0.6.
In the following script I try to update a row and it works properly
but when I try to insert a new one, it doesn't work,
there's no messages but the row is not inserted into the table.
Is this the right way ?
from sqlalchemy.orm import sessionmaker
Session = sessionmaker(autoflush=True)
session = Session()
#update an existing row... it works
old = Specie.get('D')
old.specie_descrizione='dog'
#insert a new row... it doesn't work
new=Specie(
specie_codice='C',
specie_descrizione='cat'
)
session.commit()
thanks for any help

in my disperation, I tried also the following, but without success: :-(
from sqlalchemy.orm.session import Session
session=Session(autoflush=True,autocommit=True)
class Gruppo:
pass
mapper(Gruppo,
tbl['gruppo'],
column_prefix = 'gruppo_',
)
session.begin()
> <sqlalchemy.orm.session.SessionTransaction object at 0x28a9710>
new=Gruppo( gruppo_id = 1, gruppo_descrizione='cat')
session.commit()
print Gruppo.get(1)
>SELECT gruppo.id AS gruppo_id, gruppo.descrizione AS
gruppo_descrizione
>FROM gruppo
>WHERE gruppo.id = %(param_1)s
>Col ('gruppo_id', 'gruppo_descrizione')
>None
I don't understand what's wrong. I can't INSERT a new record into a
table.
Could someone, give me some help?
Would this (not) work?
from sqlalchemy import *
from sqlalchemy.orm import mapper
metadata = MetaData()
groups = Table('groups', metadata, Column('id', Integer,
primary_key=True), Column('name', String(25)))
class Group(object):
pass
mapper(Group, groups)
from sqlalchemy.orm import sessionmaker
Session = sessionmaker()
session = Session()
group = Group()
group.name = 'cat'
session.add(group)
session.commit()
session.expunge_all()
group = session.query(Group).first()
print group.id
session.close()
