Django snippets

# 1. In settings.py add something like this:

import logging
logging.basicConfig(
    level=logging.NOTSET,
    format='%(asctime)s %(levelname)-8s %(message)s',
    datefmt='%m-%d %H:%M',
    #change as needed
    filename='/path/to/log/dir/my-log-file.log', 
    filemode='a'
)
logging.getLogger('').setLevel(logging.NOTSET)


# 2. In settings.py add '<myapp>.middleware.trace.TraceMiddleware' 
# to MIDDLEWARE_CLASSES.


# 3. Then in <myapp>/middleware create trace.py:

import logging, datetime

class TraceMiddleware(object):
    def process_request(self, request) :
        logging.info(
            "%s %s" % (request.META['REQUEST_METHOD'],
            request.get_full_path())
        )
        request.started = datetime.datetime.now()
        return None

    def process_response(self, request, response) :
        delta = (datetime.datetime.now() - request.started)
        logging.info(
            "<- Response in: %f sec.",
            delta.seconds + (delta.microseconds / 1000000.0)
        )
        return response

    def process_exception(self, request, exception):
        logging.exception("*** EXCEPTION ***")


# 4. Enjoy luxury of the logging API in your code:

    ....
    logging.debug('Redirecting to the home page')
    return HttpResponseRedirect('/')
