If you'd like more fine-grained control, you can write and add to your settings a middleware class which defines a method named process_exception(), which will have access to the exception that was raised: http://docs.djangoproject.com/en/dev/topics/http/middleware/#process-exception Your process_exception() method can then perform whatever type of logging you'd like: writing to console, writing to a file, etc., etc. Edit: though it's a bit less useful, you can also listen for the got_request_exception signal, which will be sent whenever an e

Django 500 Internal Server Error

Join them; it only takes a minute: Sign up Django not logging all errors up vote 1 down vote favorite I have the following logging config set up in Django 1.8: LOGGING = { 'version': 1, http://stackoverflow.com/questions/238081/how-do-you-log-server-errors-on-django-sites 'disable_existing_loggers': False, 'handlers': { 'file': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': normpath(join(DJANGO_ROOT, '../../logs', 'django.log')), }, }, 'loggers': { '': { 'handlers': ['file'], 'propagate': True, 'level': 'DEBUG', }, }, } Moreover, I'm also logging the stdout and stderr of gunicorn into two separate files via supervisord. My problem is that not all errors are showing up in Django logs. For example, there is a case when I had a simple .get() query in a model's save function, which http://stackoverflow.com/questions/30735669/django-not-logging-all-errors raised a DoesNotExist exception in the admin page. This exception did not show up at all in any Django log, all I could see was the 500 in the nginx log for a POST request. When I tried with debug mode in local machine, it produced the detailed error page, but what if I couldn't reproduce a bug in a local machine? Why are 500 errors silently disappearing in Django and how can I fix it? // I know that Sentry is able to report such exception errors, I'm looking for a way which doesn't involve using an external service. python django logging nginx mandrill share|improve this question edited Jun 10 '15 at 21:33 asked Jun 9 '15 at 14:55 zsero 3,431135192 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote I debugged the case, it was a combination of two things: Without specifying SERVER_EMAIL, Django sends admin emails from root@localhost. The SMTP provider I'm using (Mandrill) silently blocks all emails from such address, thus I never got the emails, nor any log at Mandrill. Solution was to specify SERVER_EMAIL to a real address and test admin email sending using mail_admins(). django.security and django.request loggers are set not to propagate by default, thus my root logger '' did not catch them. Solution was to re-specify them and set propagate to True. This way t
log errors to stderr? Why can't I see Django exceptions in the console? How do I get Django to log exceptions? How to print debug messages in Django? I know they're common because I've often found http://www.obeythetestinggoat.com/how-to-log-exceptions-to-stderr-in-django.html asking myself some kind of variant on these questions, at some point or other. Then I saw that, in Django 1.6/1.7, the default logging configuration actually does send logging messages to the console So does this mean that exceptions in Django are going to start appearing in the console then? No. Just because you wish for it doesn't make it so I think my own difficulties with this issue stemmed from the fact that, obviously, in my mind, 500 error the thing you'd want to log would be exceptions, and that, since Django will show us a clever debug page (if DEBUG is True), or a standard server 500 page, then I sort of assumed it would log that exception as well. But it doesn't The reason I struggled with this because I wasn't clear on the fact that there are actually two systems involved here: Django's logging system (based on the Python logging module) Django's exception handling layer django 500 error (middleware) By default (as of Django 1.6), Django is configured to send logging messages to the console. There are two gotchas however: Django's default logging level is set to WARNING, which means any attempt to use logging.debug or logging.info will fail Django has a middleware layer that automatically catches exceptions, and handles them differently depending on whether you have DEBUG = True or not, but it doesn't explicitly log them. Unit testing Django's logging config (if you want) This is a blog about TDD, so let's write a test first. It works by monkey-patching in an extra view function into the project's url config (mwahahaha). The view then tries to do various calls to, eg, logging.debug, just we'd like to be able to in our real views. Finally it explodes with an exception, so we can test whether any information about the exception ends up in the logs We mock out sys.stderr to pick up on what was actually sent to the console. # test assumes django 1.6 and project called 'myproj' # also assumes this file is saved in myproj/myproj/test_logging.py, # ie in the same folder as settings.py from django.test import TestCase from django.conf.urls import url from unittest.mock import patch import logging import sys from django.http import HttpResponse from .urls import urlpatterns from .settings import DEBUG # django.conf.settings are messed with by test runner def do_logging(request): # dummy view that tries to log a
