Hello!
I'm having this error in a query
[[ session.query(Extrato).filter_by(t_bank='IF5',
t_dtmv='2007/07/27') ]]
If I execute the query in the shell, or webconsole, no error hapens,
and get the results I expect!
I have turbogears 1.0.4b3 with SQLAlchemy 0.4.1 running in Linux
(Ubuntu7.10) and acessing a MSSQL database with pymssql.
File "/home/paulino/Developer/tgears/tg/tg/subctrls/extrato/Ctrl.py",
line 71, in guardar
session.query(Extrato).filter_by(t_bank='IF5',
t_dtmv='2007/07/27')

entity_name=entity_name), self, **kwargs)

raise exceptions.InvalidRequestError("Class '%s' entity name '%s'

InvalidRequestError: Class 'Extrato' entity name 'None' has no mapper

thanks,
