create a new, empty MetaData instance. redefine=True didnt work so
great since tables have dependencies on each other.
thanks for the answer,
I just saw that redefine is still in the docstring for 0.3s Table class.

OK, i had the impression you were switching the mapper inside of a
relation() somehow, but it seems all youre doing is sticking a mapper
on a property (i dont quite understand how youd use it ? )
if i understand properly, id just do it this way:

Hi,
I'm still experimenting SA features and, once again, I'm stucked with a
relation definition problem.
This is the deal.
Considering this tables definition :
USERS = Table('users', metadata,
Column('id', Integer, primary_key=True),
Column('name', String(255), nullable=False),
)
it all looks fine to me, youd have to show me something more specific.

Here is an attached sample of my problem.
You can create a User, u, and a Folder, f. Assign ownership via a
simple f.owner = u.
You can do an :
objectstore.save(u)
objectstore.save(f)
You can see relations via
print f.owner
print u.objects
But this can not be saved into the database. An

1. Base polymorphic_identity on select criteria (no type column).
2. Use two levels of inheritance.
The first objective seems to be met, but the second is not working
properly. I put in two Managers, two
sqlite's autoincrement feature does not work when you define a
composite primary key. youll have to set the id attribute on each

Hello,
I'm using sqlalchemy.mod.threadlocal with object mappers and sessions,

I have a versioned repository of SQL DDL that I'd like to convert to
versioned sqlalchemy models, using the Table(...,autoload=True)
feature.
I suspect it may be a lossy operation to do so, but in the interest of
table documentation, is there a way to render the Table.__repr__() with

__repr__() really annoys me because no matter what i do with it, people
tell me im using it incorrectly. technically, __repr__() is supposed
to return a string that when eval'ed would return the object instance.
which is not realistic for an object like Table since its an enormous
construction.

Thanks for the feedback. The code I put up is not part of any real
system. I'm just playing off of the existing examples in the docs and
trying to get comfortable with SA inheritance.
