Dear all,
I'm having troubles accessing DB data from a function registered as a
startup hook in my TG2 application.
Minimalist code to illustrate:
def on_startup():
print DBSession.query(User).count()
tg.hooks.register('startup', on_startup)
It works like a charm in a shutdown hook, but in the startup hook an
exception is raised: "*UnboundExecutionError: Could not locate a bind
configured on Mapper|User|user, SQL expression or this Session.*".
I understand in this case the DBSession is not ready when the startup hook
is called, but I don't see another hook that would fit.
I defined the hooks in *app_cfg.py*, as I understand this is the common
practice. Should the startup hook be defined elsewhere in that case?
Thank you and best regards,
