Here is a handy little logger I wrote for Django. Feel free to use it if you want and to give me your thoughts on improvements. It was my first stab so be gentle.

Big thx to… http://www.linuxjournal.com/article/5821 for exception formatting code…

netflippers.py

from django.conf import settings
import logging
import sys
import traceback

class NFLogger():

    """
        The only requirement for this logger is that you have LOG_FILE
        set in your settings.py
    """
    def __init__(self):
        logging.basicConfig(level=logging.DEBUG,
                    format='%(asctime)s %(levelname)s %(message)s',
                    filename=settings.LOG_FILE)

    """
        Static method that will call any of our members based on a string name
        for example: NFLogger.message(sys.exc_info(),"exception")
    """
    @staticmethod
    def message(message,methodname='debug'):
        logger = NFLogger()
        if hasattr(logger, methodname):
            _member = getattr(logger, methodname)
            _member(message)
        else:
            logger.debug(message)

    def info(self,message):
        logging.info(message)

    def error(self,message):
        logging.error(message)

    def warn(self,message):
        logging.warn(message)

    def critical(self,message):
        logging.critical(message)

    def debug(self,message):
        logging.debug(message)

    """
        This will output formatted info about the current exception.
        Just pass sys.exc_info() from inside your except block
    """
    def exception(self,sys_exc_info):
         cla, exc, trbk = sys_exc_info
         excName = cla.__name__
         try:
             excArgs = exc.__dict__["args"]
         except KeyError:
             excArgs = “”
         excTb = traceback.format_tb(trbk)
         logging.error(”nException Name: %snException Arguments: %snException Traceback: %sn”,excName, excArgs, excTb)

Just stick this in your Django app and set the path to your desired log file in your settings.py and you should be good to go.

In settings.py

LOG_FILE = '/tmp/pervade.log'

In your code

from pervade.netflippers import NFLogger
NFLogger.message("hi there")

or

NFLogger.message("hi there","info")

Or in an except block:

import sys

try:
    somecode.thaterrorsout
except:
    NFLogger.message(sys.exc_info(),"exception")
