Hi,
I'm using the middleware from a snippet [1] so I could debug
exceptions raised by ajax calls. That snippets simply displays the
traceback in the console when an exception occurs:
class ConsoleExceptionMiddleware:
def process_exception(self, request, exception):
import traceback
import sys
exc_info = sys.exc_info()
print "######################## Exception
#############################"
print '\n'.join(traceback.format_exception(*(exc_info or
sys.exc_info())))
print
"################################################################"
#print repr(request)
#print
"################################################################"
It was working very well for a while, and then I realised it didn't
work any more. The middleware is almost never called when an exception
is raised (500 error with ajax calls). What is weird is that it does
work, but rarely (say one time out of 20), under some conditions that
I can't reproduce.
I don't know what I've done and that caused that strange behaviour.
Here are my settings:
MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.middleware.doc.XViewMiddleware',
'django.middleware.locale.LocaleMiddleware',
'custom_django_utils.middlewares.LoginMessageMiddleware',
'commons.middlewares.AuthRequiredMiddleware',
'custom_django_utils.middlewares.ConsoleExceptionMiddleware',
)
if DEBUG == True:
MIDDLEWARE_CLASSES +=
('custom_django_utils.middlewares.ConsoleExceptionMiddleware',)
Any idea what's going on?
Thanks a lot!
Julien
