It works pretty well. How about a small

can you add a trac ticket and use

Hi there,
Quick question - is it possible to get a custom comparator to work
with order_by?
At present my code based on SA/examples/vertical/dictlike-
polymorphic.py raises a NotImplementedError when attempting to use the
value in an order_by statement.

Is there an API-stable way to create a polymorphic instance from only the
type discriminator key? I've got a case where I need to create a mapped
instance from some JSON data that contains the type discriminator, but I'd
rather get the (key -- mapped class) from the sqla map and not maintain my

I merged the two tables into a single one, changed the mapping but the

The mapper for the base class has a property called polymorphic_map
which is a dictionary whose keys are the discriminator values and
whose values are the mappers of the associated classes (you can get
from there to the actual class via the mapper's class_ property).
I can't speak to whether
offsets and transaction need to be combined into one relation with
a backref() so that an attribute set on one side generates a
collection add on the other. Backrefs are described in the ORM
tutorial and mapper configuration docs, to send arguments to a backref
use the backref() function

Hello,
I'm trying to use SQLAlchemy for my Python project which is a multi-
threaded application. While I've had good success in performing CRUD
operations with a single thread, I'm having a lot of trouble when I
start using multiple threads.
Can anybody give a simple example of using the
Just an FYI, in PostgreSQL 8.2.4 they added a new feature returning

value of serial columns) when inserting records:
test=# create table foo ( id serial primary key not null, name text );
test=# insert into foo ( name )
