django的logging模块

1.在settings使用例子

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'simple': { # exact format is not important, this is the minimum information
            'format': '%(asctime)s %(name)-12s %(lineno)d %(levelname)-8s %(message)s',
        },
    },
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
            'formatter': 'simple',
        },

        'mail_admins': { # Add Handler for mail_admins for `warning` and above
            'level': 'ERROR',
            'class': 'django.utils.log.AdminEmailHandler',
        },
        'file': {
            #'level': 'INFO',
            'class': 'logging.FileHandler',
            'formatter': 'simple',
            'filename': os.path.join(os.path.dirname(BASE_DIR), 'recruitment.admin.log'),
        },

        'performance': {
            #'level': 'INFO',
            'class': 'logging.FileHandler',
            'formatter': 'simple',
            'filename': os.path.join(os.path.dirname(BASE_DIR), 'recruitment.performance.log'),
        },
    },

    'root': {
        'handlers': ['console', 'file'],
        'level': 'INFO',
    },

    'loggers': {
        "django_python3_ldap": {
            "handlers": ["console", "file"],
            "level": "DEBUG",
        },

        "interview.performance": {
            "handlers": ["console", "performance"],
            "level": "INFO",
            "propagate": False,
        },
    },
}
STATIC_URL = '/static/'

2.在myrecrument/interview/admin.py

logger = logging.getLogger(__name__)
def my_fun(self):
　　logger.info('user: %s ,exported  %s candicate records'%(request.user,len(queryset)))

3.日志的输出

[12/Jan/2021 17:39:56] "GET /admin/jsi18n/ HTTP/1.1" 200 3187
2021-01-12 17:40:09,665 interview.admin 42 INFO     user: admin ,exported  3 candicate records
