hello friends,
i'm happily using sa, both with a declarative/elixir orm, and directly through
DBSession.execute(text statement).
there is an issue that works great with orm, but i don't khown how to achieve in
direct execution:
image fields.
i'm inserting the data as:
sql = insert

Correction. It was cherrypy's fault. It uses 'implicit' locking of web sessions
by default ('tools.sessions.locking'). We changed it to 'explicit' and call
web_session.acquire_lock() / web_session.release_lock() manually when we need
to. This works like a charm!

blobs are problematic, and this is often highly dependent on DBAPI version and
platform.
So can you send along details:
1. python version
2. operating system
3. SQLAlchemy version
4. DBAPI in use, version
I can give it a test on this end.

hello michael,
as usually, you were faster than me to answer.

i've just found the answer:
a bytearray is needed as sql param. i've built the buffer from an image with

im = Images.new()

Hello,
today I've been bit again by a one-to-many relation not updating when
its underlying foreign key changed. This feels inconsistent, especially
since its behavior depends on whether the relationship was referenced
before the change or not.

I've been dealing with Twisted since the beggining of my ages with Python :)
What I can say: it's not an easy job. Here's what I see working:
1. Use Twisted Perspective Brokers to do the database job for you,
AFAIK is the most used combination of Twisted + SQA;
2. Use other types of message
I'm looking forward to Pep3156 (http://www.python.org/dev/peps/pep-3156/)
finally producing a working integration between Twisted and Gevent. Or
whatever Nick Coghlan wants to come up with, since he among anyone has the most
crossover knowledge of the async / ORM-related worlds I've seen.
That's cool. I made some tests with a GeventReactor with SQLAlchemy
and the psycopg green implementation. The results were ~20% faster in
almost all benchs I made, but I didn't tested them in production yet.

'relation' wasn't there.
The fix is to call orm.configure_mappers(), which happens by magic at
