Logging

I am not very happy with my logging set-up at the moment. Need to spend time working out how to use it properly.

Development

LOGGING = {
    "version": 1,
    "disable_existing_loggers": False,
    "handlers": {
        "file": {
            "level": "DEBUG",
            "class": "logging.FileHandler",
            "filename": "logger.log",
        }
    },
    "loggers": {
        "": {"handlers": ["file"], "level": "DEBUG", "propagate": True}
    },
}

Live

This is my set-up at the moment in base.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'formatters': {
        'standard': {
            'format': "[%(asctime)s] %(levelname)s [%(name)s:%(lineno)s] %(message)s",
            'datefmt': "%d/%b/%Y %H:%M:%S"
        },
    },
    'handlers': {
        'null': {
            'level':'DEBUG',
                'class':'django.utils.log.NullHandler',
        },
        'logfile': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': "logger.log",
            'maxBytes': 500000,
            'backupCount': 10,
            'formatter': 'standard',
        },
        'console':{
            'level':'INFO',
            'class':'logging.StreamHandler',
            'formatter': 'standard'
        },
    },
    'loggers': {
        'django': {
            'handlers':['console'],
            'propagate': True,
            'level':'WARN',
        },
        'django.db.backends': {
            'handlers': ['console'],
            'level': 'DEBUG',
            'propagate': False,
        },
        '': {
            'handlers': ['console', 'logfile'],
            'level': 'DEBUG',
        },
    }
}

To add logging to a module:

import logging

# after imports
logger = logging.getLogger(__name__)

# in the code
logger.critical(
    'payment check: invalid {} != {}'.format(
        payment_pk, payment.pk,
))
