Hi,
I've an error when I try to execute a clear() method from session
object.
Traceback (most recent call last):
File "V:\nacer\bin\gui\planilla.py", line 280, in
on_btn_apply_clicked
self._savePlanilla()
File "V:\nacer\bin\gui\planilla.py", line 200, in _savePlanilla
PlanillaService().save(planilla)
File "V:\nacer\bin\common\services.py", line 16, in save
session.clear()
File "c:\programs\python25\lib\site-packages\sqlalchemy-0.4.2p3-
py2.5.egg\sqlalchemy\orm\session.py", line 577, in clear
self._unattach(instance)
File "c:\programs\python25\lib\site-packages\sqlalchemy-0.4.2p3-
py2.5.egg\sqlalchemy\orm\session.py", line 1039, in _unattach
if instance._sa_session_id == self.hash_key:
AttributeError: 'PlanillaDet' object has no attribute '_sa_session_id'
I do,
session.save_or_update(dataset)
session.flush([dataset])
session.clear()
Why this error ocurr?
TIA.
