How do I define a settings.LOGGING so that gunicorn will find the version value it wants?

Question

I am trying to run Gunicorn, and I am running into an error (pasted below). At present it looks like Gunicorn or one of its dependencies is attempting to read settings.LOGGING, and the settings.py file does not appear to define a settings.LOGGING.

So I'd like to know what sort of literal or other code I can add so that Gunicorn + dependencies have what they think they need.

Code paste:

Answer 1

I had the same error and I fixed it by adding logging configuration to the project's settings file, I used the example from this page

https://docs.djangoproject.com/en/dev/topics/logging/

here is the code from my settings file

LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'formatters': {
        'verbose': {
            'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'
        },
        'simple': {
            'format': '%(levelname)s %(message)s'
        },
    },
    'handlers': {
        'null': {
            'level': 'DEBUG',
            'class': 'logging.NullHandler',
        },
        'console':{
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'simple'
        },
        'mail_admins': {
            'level': 'ERROR',
            'class': 'django.utils.log.AdminEmailHandler',
            'filters': [],
        }
    },
    'loggers': {
        'django': {
            'handlers': ['null'],
            'propagate': True,
            'level': 'INFO',
        },
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': False,
        },
    }
}

Answer 2

The easiest way is to add in settings.py:

LOGGING = {
    'version': 1,
}
