"msg" doesn't support with python format

[agusmakmun]

I don't realy know why the "msg" doesn't support with python format, eg: %s, %d, etc. I want to record all logs of django request in mongodb,
Here is the result example in mongodb;

But, when I test it in ./manage.py shell, it worked fine.

@gnulnx, can you correcting my logging please? Here is my LOGGING.

import datetime

NOW = datetime.datetime.now()
DAY_NAME = NOW.strftime('%A').lower()

MAXIMUM_FILE_LOGS = 1024 * 1024 * 10  # 10 MB
BACKUP_COUNT = 5

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'standard': {
            'format': '[%(levelname)s] %(asctime)s %(name)s: %(message)s'
        },
    },
    'handlers': {
        'default': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': 'logs/default.log',
            'maxBytes': MAXIMUM_FILE_LOGS,
            'backupCount': BACKUP_COUNT,
            'formatter': 'standard',
        },

            'level': 'DEBUG',

            # Set the connection string to the mongo instance.
            'connection': 'mongodb://localhost:27017',

            # define mongo collection the log handler should use.  Default is mongolog
            # This is useful if you want different handlers to use different collections
            'collection': 'mongolog',
            'formatter': 'standard',
        },
        'request_debug_handler': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': 'logs/request_debug.log',
            'maxBytes': MAXIMUM_FILE_LOGS,

            'backupCount': BACKUP_COUNT,
            'formatter': 'standard',
        },
        'mail_admins_handler': {
            'level': 'ERROR',
            'class': 'django.utils.log.AdminEmailHandler',
            'email_backend': 'django.core.mail.backends.smtp.EmailBackend'
        },
    },
    'root': {
        'handlers': ['default', 'mongolog'],
        'level': 'DEBUG'
    },
    'loggers': {

            'handlers': [
                'mongolog',

                'request_error_handler',
                'mail_admins_handler'
            ],
            'level': 'DEBUG',
            'propagate': False
        },
    }
}

This doesn't function in the same way as normal python logging so there isn't any perform hit doing the string interpolation in the normal fashion like so:

log.info("this is test info: %s" % info)

But I do tend to agree that since it's a logger it should behave normally. I'll keep this ticket open and get around to it eventually.

Thanks.
