stupid Python logging woes

Recently moved a project to Django 1.3 and I kept seeing duplicate messages for all of my logger.x messages, even though my LOGGING dictionary looked like:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'loggers': {
        'base': {
            'level': 'DEBUG',
        },
    }
}

I simplified it to this to see if there were any issues, and although I define no handlers for the ‘base’ logger, it still was printing out logging messages. I did a grep on the entire virtualenv libraries for basicConfig or BASIC_FORMAT to see if any of my external libraries were misbehaving and didn’t find anything. I went through my codebase again and got rid of some extraneous logging.debug in some files and that fixed it. So always use

import logging
logger = logging.getLogger(__name__)
logger.debug(....)

instead of logging.debug directly!
