I am having a problem using the logging utility in Python using the logging module from the std. lib. I have written a class SPFLogger which actually should be creating a new logger if one already does not exist. I have given the class I wrote in the end. The problem I am facing is:
I am creating 2/3 object of this class SPFLogger in 2/3 other classes of mine having different logger name and the handler they will be using. Although the logs are going in a single file which means the logging.getLogger(name) function is getting the same logger which was created earlier and not creating a new logger with new handler. Eventhough the logs are going in a single file the loggers names used are different which I am passing as an argument.
So for example if I do this first in the init method of class A:
obj1 = SPFLogger ("A", "A.log")
logger1 = obj.getLogger()
logger1.info("Message A") ----> Goes in A.log with logger name A
now class A calls class B so in the init method of class B I have:
obj2 = SPFLogger ("B", "B.log")
logger2 = obj.getLogger()
logger2.info("Message B") ----> still goes in A.log with logger name B ..
Is there something that needs to be done to handle this? Below is the code for SPFLogger class
