Hello,
I'm having a problem trying to cleanup sqlalchemy objects. My application
has a thread which handles DB connections. In some cases the thread dies
and I want to do a cleanup so, next time the thread is started it would be
able to reconnect again.
The steps I tried are:
self.metadata.clear()
self.engine.dispose()
self.session.close()
self.conn.close()
But when I start a new thread, errors like this appear:
sqlalchemy.exc.ArgumentError: Column object 'column' already assigned to
Table 'table'
