Thanks for the pointer. Problem solved :)

I have trouble configuring two relationships from one class to another. The
following code should be fairly self-explanatory:
from sqlalchemy import *
from sqlalchemy.orm import *
from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
class Company(Base):
Thanks Michael. As always I appreciate the support here.
I'll try it out. It might actually be faster to redo these two tables in
the model in plain SQLAlchemy than trying to figure out what's wrong with
the current one.
And, uhm, there is no difference between user_account and workers. I
also in 0.8 I'm definitely going to make it so that primaryjoin thing isn't
needed for this kind of case, foreign_keys=foo.id will be enough, see
http://www.sqlalchemy.org/trac/ticket/2411 .

Awesome =)
Your example definitely works.
But given my nature, I cannot leave things like this unanswered. So I took
a few steps back and debugged some more.
I removed a few fields from the model and added them one by one with
elixir. When using reverse I actually had to specify the field on

Hi again, sorry for flooding with email this week...
I stumbled on the CircularDependencyError in some occasions with self
referencing models. I do understand that it can be tricky to INSERT and DELETE
but I'm just updating rows.
I reduced my problem to the bare minimum. It works both on 0.5.8
need a full test case. Here's yours, runs fine:
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import *
from sqlalchemy.types import *

Base = declarative_base()
e = create_engine('sqlite://', echo=True)
Base.metadata.bind = e

of course you'll get a cycle if you do this, though:

d1 = School(cod=D1, cod_riferimento=S1, cliente=False)
s1.sedi = [s1, d1]
s1-s1 is not supported by self referential flushes, unless you put
post_update=True on the relation() you have
