Hi,I'm trying to add the logging module to my application, but I seem to be missing something. My application (a wxPython one) has a main script that calls various helper classes. I want the log messages from all modules to go to one central log file. When I implement logging, I think that due to preparation, I get the same message more than once. Here's an example: $ cat -n server.py 1 import logging 2 import logging.handlers 3 4 class Server(): 5 def __init__(self): 6 self.client_logger = logging.getLogger("client") 7 self.client_logger.setLevel(logging.DEBUG) 8 h = logging.FileHandler("client.log") 9 h.setLevel(logging.DEBUG) 10 formatter = logging.Formatter("%(asctime)s %(name)-12s %(levelname)-8s %(message)s") 11 h.setFormatter(formatter) 12 self.client_logger.addHandler(h) 13 14 def util(self): 15 self.client_logger.warning('This message comes from Server module') $ cat -n client.py 1 import logging 2 import logging.handlers 3 from server import Server 4 5 class Client(): 6 def __init__(self): 7 self.client_logger = logging.getLogger("client") 8 self.client_logger.setLevel(logging.DEBUG) 9 h = logging.FileHandler("client.log") 10 h.setLevel(logging.DEBUG) 11 formatter = logging.Formatter("%(asctime)s %(name)-12s %(levelname)-8s %(message)s") 12 h.setFormatter(formatter) 13 self.client_logger.addHandler(h) 14 15 def client_test(self): 16 self.client_logger.warning("This message comes from Client module") 17 18 if __name__ == "__main__": 19 ser = Server() 20 cli = Client() 21 ser.util() 22 cli.client_test() $ rm client.log ; python client.py ; cat client.log 2009-11-24 14:40:39,762 client WARNING This message comes from Server module 2009-11-24 14:40:39,762 client WARNING This message comes from Server module 2009-11-24 14:40:39,762 client WARNING This message comes from Client module 2009-11-24 14:40:39,762 client WARNING This message comes from Client module Googling and reading http://docs.python.org/library/logging.html didn't enlighten me. Could you suggest what should I change in the above scripts so that the log messages would appear only once ? Thanks, Ron.
Have a look at http://docs.python.org/library/logging.html#logger-objects First thing mentioned is Logger.propagate which is, what I believe, you're looking for ;) -- Soltys "Free software is a matter of liberty not price" -- http://mail.python.org/mailman/listinfo/python-list
