The only way, that was working for me was connecting myself to the
got_request_exception signal of the django framework.
so what I do now is:
import sys
import traceback
from django.dispatch import receiver
from django.core.signals import got_request_exception
import logging
logger = logging.getLogger('exceptionlogger')
@receiver(got_request_exception)
def got_request_exception_hndlr(signal, **kwargs):
request = kwargs.get('request')
meta = request.META
logger.error("ReqException %s %s" %
(meta['REMOTE_ADDR'], request.path ))
ex_type, ex_value, _e_b = sys.exc_info()
logger.error(traceback.format_exc())
This code has of course to be imported as soon as possible in order to
catch as many exceptions as possible.
What would be the correct place for it?
- First line of urls.py?
- import it as dummy middleware?
