Hi
i am not sure if this is an issue related to turbogears or sqlalchemy.
if i try to access a property of an object after doing a
transaction.commit() i get this UnboundExecutionError
UnboundExecutionError: Parent instance <User at 0x9a29b10> is not
bound to a Session; lazy load operation of attribute 'config' cannot
proceed
I have to do transaction.commit() to update the database immediately
so that other requests to this
object will get the updated value.
No, you don't. That's what DBSession.flush() is for. As you claim it's
not working, there might be something wrong with your model-setup.
Try setting the engine to debug-mode via
engine.echo = True
in your setup so that you can see what SQL is produced. If on flush
nothing happens, you need to investigate - I have seen problems with
this when different sessions are used involuntarily.
