[TurboGears] Re: elixir with turbogears2
I have moved the code out of Elixir and using tg sqlalchemy itself.
For now, I am not seeing the issue. This has brought up a new issue though,
AdminController updates are not working.
I am getting:
ResourceClosedError: This transaction is closed
one after another hopefully I will get some help or resolve it.
With Regards,
Dinesh.

Hi Erisian, have you found the solution for this? I got stuck with the same issue. Please help. With Regards, Dinesh.

[TurboGears] Admin controller issue with ZTE
Hi All, I am using the following statement to create DB session maker = sessionmaker(autoflush=True, autocommit=False, extension=ZopeTransactionExtension()) DBSession = scoped_session(maker) and in my app, I have created model view admin controllers for user,group etc. when I try to edit users, I am hitting the following issue. File "/remote/vtghome9/vgtools2/VPython2.7.13/lib/python2.7/site-packages/transaction/_transaction.py", line 423, in _commitResources rm.tpc_vote(self) File "/remote/vtghome9/vgtools2/VPython2.7.13/lib/python2.7/site-packages/zope/sqlalchemy/datamanager.py", line 109, in tpc_vote self.tx.commit() File "/remote/vtghome9/vgtools2/VPython2.7.13/lib/python2.7/site-packages/sqlalchemy/orm/session.py", line 459, in commit self._assert_active(prepared_ok=True) File "/remote/vtghome9/vgtools2/VPython2.7.13/lib/python2.7/site-packages/sqlalchemy/orm/session.py", line 285, in _assert_active raise sa_exc.ResourceClosedError(closed_msg) ResourceClosedError: This transaction is closed Any help is greatly appreciated.!! Possible issue:: Since ZTE is used, calling .commit() explicitly is not required. is there a way to handle this to create different session (without ZTE) for AdminController to use?
