Using Python 2.5.1, I can not get this example to work :
http://svn.sqlalchemy.org/sqlalchemy/tags/rel_0_4_1/examples/vertical/vertical.py
It crashes with :
Traceback (most recent call last):
File "vertical.py", line 161, in <module>
session.save(entity3)
...
sqlalchemy.exceptions.InvalidRequestError: Instance
'[EMAIL PROTECTED]' is with key (<class '__main__.EntityField'>,
(1,), None) already persisted with a different identity
I do not know why. Any clue ?
Thanks !
