Hi,
I'm using SQA core to improve my app performance.
I'v got the following db update request:
engine.execute(Person.__table__.update().\
where(Person.name == peter).\
values(is_stafff=True))
When peter does not exist, is there a
()
my_object = session.query(...).one()
session.refresh(my_object) # - is this line needed?
return my_object
Thanks again for your time supporting a newbie.

Is this a correct way to achieve multi-process correct behaviour?
Thanks

Thanks for your comments.
I'm using sqlite in default mode (which is synchronous) and here's my engine
configuration.

Hi,
Newbie question on relationships.
Consider the following code.
When deleting a child, I would like the parent *.children* attribute to be
automatically updated by the orm.
It is not : am I doing something wrong or missed some configuration ?
Thanks a lot!

Hi,
Sorry for the previous post. Attached script had a typo.

automatically updated...
Am i doing something wrong or missed some configuration ?
Please note that i'm using sqa 0.8.4.

HI everyone,
First, i would like to thank you for your comments.
Then, for those who run linux, the following works:
1- copy your db.sqlite to /dev/shm/db.sqlite (thus in ram fs)
2- play with it through sqlalchemy
3- backup it to disk when needed

Hi,
I'm currently running several python applications (each app using
sqlalchemy) accessing (read/write) a single SQLite database stored on disk.
For performance reasons, I would like to store this db file in RAM memory
(ie, in my /dev/shm)
The applications would then access a shared
Hi,
In order to improve the underlying SQLite performance, I've changed some
low level settings with PRAGMA commands:
PRAGMA synchronous=NORMAL; /* instead of default FULL value, see:
http://www.sqlite.org/pragma.html#pragma_synchronous */
PRAGMA journal_mode=WAL; /*
Example code is:
orm = OrmManager()
session = orm.get_session()
my_obj = session.query()
my_obj.attribute = 'new value'
session.commit()
I can see an issue here, talking to you. We used the SingleThreadedPool
with pool_size=50. But looking at our code, it seems that we never
Hi,
For some reason, I need to access my sqlite database through an API which
encapsulates the sqlalchemy stuff.
In my api methods, the typical sequence is:
1. get a session from the session maker
2. query/commit the db using this session
3. return the queried/commited object and close
Worked perfectly. Thanks a lot for your quick answer and so great software.

We tried to switch from SingletonThreadPool (which raises errors,
sometimes) to StaticPool... we'll see what happens. The problem is
that this error is not systematically raised and it seems that it is
raised when multiple threads are accessing the db.
StaticPool can't be used for
