Hi all, is this:

the new default, preferred way of using SQLalchemy with Pylons? It
seems now I have to add something like:
engine = engine_from_config(config, 'sqlalchemy.')
init_model(engine)
otherwise I get errors

Yes. If you create a new app in Pylons' development version

Care to change it to a I-know-who-my-session-is model? As you can see

Great stuff Mike, especially the part when you mention that pylons

Now my head is spinning, I read the SQLAlchemy docs:
http://www.sqlalchemy.org/docs/tutorial.html#tutorial_orm
And its approach is also different

Dear jj,
I don't have much explanation to offer except for my mere curiosity in
playing with an object database. I actually love working with SQL and
