Django Celery Logging Best Practice

Question

I\'m trying to get Celery logging working with Django. I have logging set-up in settings.py to go to console (that works fine as I\'m hosting on

Answer 1

When your logger initialized in the beginning of "another module" it links to another logger. Which handle your messages. It can be root logger, or usually I see in Django projects - logger with name ''.

Best way here, is overriding your logging config:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'formatters': {
        'simple': {
            'format': '%(levelname)s %(message)s',
             'datefmt': '%y %b %d, %H:%M:%S',
            },
        },
    'handlers': {
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'simple'
        },
        'celery': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': 'celery.log',
            'formatter': 'simple',
            'maxBytes': 1024 * 1024 * 100,  # 100 mb
        },
    },
    'loggers': {
        'celery': {
            'handlers': ['celery', 'console'],
            'level': 'DEBUG',
        },
    }
}

from logging.config import dictConfig
dictConfig(LOGGING)

In this case I suppose it should work as you assume.

P.S. dictConfig added in Python2.7+.
