[sqlalchemy] Re: Additions to model not getting flushed to DB?? (Pylons)
Doh, I should have turned on the SQL echo. Now that I have, it's even
more puzzling to me. It shows the 'contact' being inserted and
committed -- but it never appears in MySQL!
2006-12-23 17:33:15,140 INFO sqlalchemy.engine.base.Engine.0x..cc BEGIN
2006-12-23 17:33:15,145 INFO sqlalchemy.engine.base.Engine.0x..cc SELECT

2006-12-23 17:33:15,150 INFO sqlalchemy.engine.base.Engine.0x..cc INSERT INTO
contact (client_id, email, password, firstname, lastname, ts_created,
ts_updated) VALUES (%s, %s, %s, %s, %s, %s, %s)
2006-12-23 17:33:15,150 INFO sqlalchemy.engine.base.Engine.0x..cc [9L, '[EMAIL
PROTECTED]', None, None, None, datetime.datetime(2006, 12, 23, 17, 33, 44),
None]
2006-12-23 17:33:15,158 INFO sqlalchemy.engine.base.Engine.0x..cc COMMIT
#vendor.upload Query contacts after flush=[]
If I switch my Pylons development.ini to use an SQLite DB, the app
works as expected until I get to the same flush():
contact = model.Contact(client_id=client.client_id,
email=row['contactemail'],
password=row.get('contactpassword'),
firstname=row.get('contactfirstname'),
lastname=row.get('contactlastname'))
self.session.save(contact)
self.session.flush()
The Pylons traceback reports:
self.session.flush()
...
sqlalchemy.exceptions.SQLError: (OperationalError) SQL logic error or missing database 'INSERT INTO contact (client_id, email, password, firstname, lastname, ts_created, ts_updated) VALUES (?, ?, ?, ?, ?, ?, ?)' [1, '[EMAIL PROTECTED]', None, None, None, '2006-12-24 00:25:35', None]
The SQL echo looks good, until the ROLLBACK:
2006-12-23 19:25:35,874 INFO sqlalchemy.engine.base.Engine.0x..0c BEGIN
2006-12-23 19:25:35,878 INFO sqlalchemy.engine.base.Engine.0x..0c SELECT

2006-12-23 19:25:35,879 INFO sqlalchemy.engine.base.Engine.0x..0c INSERT

ts_updated) VALUES (?, ?, ?, ?, ?, ?, ?)
2006-12-23 19:25:36,031 INFO sqlalchemy.engine.base.Engine.0x..0c [1,
'[EMAIL PROTECTED]', None, None, None, '2006-12-24 00:25:35', None]
2006-12-23 19:25:36,086 INFO sqlalchemy.engine.base.Engine.0x..0c ROLLBACK
That self.session is created with a Pylons __before__ method:
def __before__(self):
self.session = session_context.current
self.q = self.session.query(model.Vendor)
and other methods use this just fine as far as I can tell.
How can I track down whether there's a missing database or what the
SQL logic error might be?
Thanks.

seems like Pylons is not properly maintaining the session within requests. unless there is some way you can reproduce this problem without any dependencies on pylons ? is this using the newest SA/Pylons code that Ben was recently working on ? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.

Yeah, it sure feels like that. :-( unless there is some way you can reproduce this problem without any dependencies on pylons ? is this using the newest SA/Pylons code that Ben was recently working on ? Hrmmm, I'm not sure ... I am not on the bleeding edge with nightly easy_install -U *=dev :-) I'll see if I can reproduce in a small scale in Pylons; if so, I'll try reproducing in standalone SA.

Hrmmm, I'm not sure ... I am not on the bleeding edge with nightly easy_install -U *=dev :-) Pylons trunk (dev) provides a session_context out of the box, but the 0.9.3 release (which it sounds like you're using) does not. Showing how your session_context variable is created might be helpful. I saw a prompt in your last email: self.session.flush() Are you using paster shell, or the interactive debugger? Otherwise nothing looks out of the ordinary minus the fact you're not seeing your data. Obvious question: are you seeing the changes made to the database after the commit? -- Philip Jenvey --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.
