I am trying to create a log level called userinfo for the pythonlogging. I read
the source code and tried to register the level to theloggingnamespace with the
following source:
fromloggingimport Logger
# create the custom log level
class userinfo(Logger):
def userinfo(self, msg,
*args, **kwargs):
if
self.isEnabledFor(WARNING):
self._log(WARNING, msg, args, **kwargs)
# Register log level in thelogging.Logger
namespace
Logger.userinfo = userinfo
Has I am sure you guessed, it did not work. If you know how this is
done or know what I am doing work or can provide a link to example
code (because I have not been able to locate any), I would greatly
appreciate it.
My sincere and heartfelt thanks in advance.
See the example script at
http://dpaste.com/hold/21323/
which contains, amongst other things, an illustration of how to use
custom logging levels in an application.

I got the code setup, however, I still get an error for my custom log
level.

I would love to know what I am doing wrong. Thanks again for your
help, it is really appreciated.
I think that custom levels don't get their own method; you have to use:
logger.log(USERINFO, 'this is a userinfo log message')
although you could add it yourself with, say:
setattr(logger, 'userinfo', lambda *args: logger.log(USERINFO, *args))
If it's not asking to much, could you show me how these would be
used ?
I tried on my own, but I keep getting errors.
