Thank you for the fast reply and the fix!
I case somebody encounters this problem and doesn't want from a
checkout, workarounds are:
In the init of the Example class, access the point or set to None:
class Example(Base):
__tablename__ = 'example'
id = Column(Integer, primary_key=True)

I never defined a 'C' or 'D' and I would like simple get a Resource when no
better mapper is found.

OK it works (not yet in tip though).

Does this mean I can use this in 7.3? or Do I need to download tip?
Also could you show me how this would work with old style mapper(...) s
instead of declarative_base?
Thanks,
Kris

Hey all, I just created a meetup group in Vancouver BC for Pyramid and
Pylons users. I'm wondering if I should really make it
Pyramid/Pylons/SQLAlchemy. At any rate, SA certainly seems to be the most
popular persistence mechanism for Pyramid. If you're in Van, I'd love to
hear from you.
works in 0.7.3. will also work in 0.7.4 Just not the current tip at the
moment.
the regular mapper() setup is equivalent (see
http://www.sqlalchemy.org/docs/orm/mapper_config.html#classical-mappings) :
discriminator_expr = case(...)
mapper(Person, ..., polymorphic_on=discriminator_expr,
I've been beating my head over this one. I read the ORM Creating a
Thread-local Context doc and the web but don't see a simple
answer...saw some old SA/Cherrypy code that used cherrypy 'tools' etc.
The SA doc seems straightforward but I keep getting
sqlalchemy.exc.UnboundExecutionError errors.

To get the class of a regular relationship, I use a class_mapper:

mapper = sqlalchemy.orm.class_mapper(cls)

Thanks Michael,
Could not find a hidden Session object.
So I broke it down into a problem that works/doesn't work based on
files separation
1. If I place all of the code into one file all_in_one.py which
contains the cherrypy startup, the SA init code and ORM object and the
cherrypy REST

I have the following setup:
...
engine = create_engine(...)
session = scoped_session(sessionmaker(..., bind=engine))
...
session.add(object)
session.commit()
What I need is to add this object *to the database*, and then select
it in some non-sql-alchemy code, and then
Please disregard this; I've solved it.

Hi John:
The following import is causing that error.
from sqlalchemy.orm import session, Session
In the all-in-one example you provided, you later go on to reassign
'session' and 'Session', replacing those imported values with your own
values.
Session =

That was it.
My weak Python understanding was my downfall!
