Writing to Heroku logs in Django

Question

I've created a project in Django and have deployed it to Heroku. Unfortunately, a number of things that were working locally, now don't work on Heroku. To troubleshoot I need to be able to write to the Heroku logs when my program runs so that I can troubleshoot better. So far I have not gotten it to work

My settings/staging.py file contains:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console'],
            'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
        },
    },
}

I have an app called accounts, so my accounts/views.py file contains:

import logging
log = logging.getLogger(__name__)

def auth_profile(request):
    log.debug('TESTING THE DEBUGGER')

When auth_profile is accessed I want to see the text 'TESTING THE DEBUGGER' show up in the Heroku logs, but so far I get nothing.

How do I get this to work?

I think if you drop a log.error you would probably see something.

I had the same problem and it turns out heroku's settings tool breaks the pre-existing LOGGING setup. The logger you are using is not registered with django but is making its own way to the console using python's standard logging system.

Try doing:

django_heroku.settings(locals(), logging=False)

Or better yet, don't use it at all anymore since this package is no longer maintained anyway.
