Logging in Django on Heroku not appearing

Question

I have created an app on Heroku and I push my Django app to it.

I monitor the logs using heroku logs --tail to see them in real time.

Your Procfile and LOGGING configuration looks fine. Django configures the logger just before the apps are imported, so if you try to log even before than (for. e.g. from settings.py file), it will not work.

EDIT:

LOGGING config:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'verbose': {
            'format': ('%(asctime)s [%(process)d] [%(levelname)s] '
                       'pathname=%(pathname)s lineno=%(lineno)s '
                       'funcname=%(funcName)s %(message)s'),
            'datefmt': '%Y-%m-%d %H:%M:%S'
        },
        'simple': {
            'format': '%(levelname)s %(message)s'
        }
    },
    'handlers': {
    'null': {
            'level': 'DEBUG',
            'class': 'logging.NullHandler',
    },
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'verbose'
        }
    },
    'loggers': {
    'ex_logger': {
            'handlers': ['console', ],
            'level': 'INFO',
        }
    }
}

adding following to settings.py won't log:

import logging
logger = logging.getLogger('ex_logger')
logger.info("core.settings logger")  # won't work 

adding to views.py should log:

from django.http import HttpResponse
import logging

logger = logging.getLogger('ex_logger')
logger.info("core.views logger")  # should work                                                                                                         

def url_please(request):
    logger.info("path: %s" % request.path)  # should work                                                                                               
    return HttpResponse(request.path)
