Assuming I define my tables using the following:
CREATE TABLE users (
id SERIAL NOT NULL,
username VARCHAR(255) NOT NULL,
PRIMARY KEY (id),
UNIQUE (username)
)
CREATE TABLE posts (
id SERIAL NOT NULL,
title VARCHAR(255) NOT NULL,
body TEXT NOT NULL,
user_id INTEGER,
PRIMARY KEY (id),
FOREIGN KEY(
nope. Jason was right :D. I needed to add Session.remove() to my
threads as well; though, I'm not sure why adding
expires_on_commit=False alone didn't solve it. Oh well, works now
Thanks!

Jason, in the contrived example I came up with and posted, your
solution worked but not in my tests. I tried both
expires_on_commit=False and Session.remove() before the drop with no
luck. Thanks for the suggestion

I reproduced the issue the script below:

Sorry for the weak explanation before. This has little to do with
being "in tests" except that's the only code that drops and creates
the db for any reason. Ctrl-C does nothing when it blocks.
Chris, try running the script i
Base.metadata.drop_all() completely blocks in the tearDown method of
some of my tests. Session is defined with
scoped_session(sessionmaker())
Any ideas how to get around this?

What's the best way to seed a db with data? I've used
DDL.execute_at('after-create', table) in the past, but is there a way
to get bind.create to run a segment of code first?

How do I detach or unload the data from a relation on an instance?
I'm writing a thin layer on top of SA for caching and need to do
serialization. The following happens when serializing:
poet = session.query(Poet).find_by(name='Haafez').one()
pickle.dumps(poet) # Only serializes the Poet object

Sorry for the late reply. Here's a decent example. I have this
working in production error free, but it's hardly done. Note, the
code below is a specific example. Let me know if you have questions
from sqlalchemy import orm
def get_session_id(session)
I used SesionExtension.after_flush. Worked great.
Thanks for the help Michael!

I wrote a simple layer on top of my models that allows them to be
easily inserted into and fetched from memcache. Now, I'm trying to
solve the easier part :) -- cache invalidation. I can use mapper
extensions, but I'm looking for a cleaner way. The biggest problem
with MapperExtension is that so
