Sqlalchemy - Updating row with a filter produces List Index Error
I do not think that your code is doing what you want it to do. There are two ways to make an update you want:
1) Directly on the database:
upd = (session.query(Clocktime) .filter(Clocktime.p_uuid == p_uuid) .update({"time_out": datetime.datetime.now()}) )print("# of updated rows = {}".format(upd))# session.commit()2) Load object(s), update the value, and commit the session
upd = (session.query(Clocktime) .filter(Clocktime.p_uuid == p_uuid) )# assuming there should be exactly one object for given p_uuid clockTime = upd.one()clockTime.time_out = datetime.datetime.now()session.commit()
