You can put the declaration of Base in a common file that is

Can this be made to work?
session = Session()
rec = MyModel() # create a record
session.close()
# Sometime later
session = Session()
rec.name = Fred # modify the record
session.commit() # try to save modified record
session.close()
Does the session have to be global to this

...and we're back to the same issue with another column_property: that

How do you create column_properties with subqueries on child objects
where the subquery references another child object? This:
PC_avgdist_subq = select([func.avg(func.distance(PC.pt.RAW,
I have the following code:
from objects import *
class Device(Base):
__tablename__=testdev
devtype = Column(Unicode(20), primary_key = True)
__mapper_args__ = {'polymorphic_on': devtype}
mac = Column(Unicode(128), primary_key = True)
switch_mac = Column(Unicode(128), ForeignKey(mac))
switch =
Trying again without tab indents. Hopefully the formatting works this
time.

Ultimately you're looking for a self-referential correlation here. In SQL,
that always implies using aliases. Your column_property needs to be against
aliased(PC) and not PC itself.
Thanks - that did the trick. I
Hi,
First message here in the sqlalchemy mailing list. I was working with
a previous version of sqlalchemy (0.6beta1) and while updating
sqlalchemy, ran into a problem with polymorphic classes. Basically
we're using a single table inheritance scheme and we want the value
column to have different
