Yes this is the result of printing:
c = se.query(Caja).get(1)
c.__dict__
{'Entidad': u'Eprueba', '_sa_instance_state':
<sqlalchemy.orm.state.InstanceState object at 0x03027570>, 'Salida': 10.0,
'Fecha': datetime.date(2015, 10, 12), 'id_Conceptos': 1, 'Grupo': u'grp',
'id': 1, 'Entrada': 50.0}
type(c)
<class 'modeloCaja.Caja'>
type(c).__dict__
dict_proxy({'Entidad': <sqlalchemy.orm.attributes.InstrumentedAttribute
object at 0x02FE8FD0>, '__module__': 'modeloCaja', '_sa_class_manager':

sys.modules[type(c).__module__]
<module 'modeloCaja' from 'modeloCaja.pyc'>
My sa.vesion is *0.7.10*
Can it be that the version is out of date?
I appreciate all your efforts to resolve.
