django设置打印数据库日志

在settings.py中添加：

LOGGING = {
    'disable_existing_loggers': False,
    'version': 1,
    'handlers': {
        'console': {
            # logging handler that outputs log messages to terminal
            'class': 'logging.StreamHandler',
            'level': 'DEBUG', # message level to be written to console
        },
    },
    'loggers': {
        '': {
            # this sets root level logger to log debug and higher level
            # logs to console. All other loggers inherit settings from
            # root level logger.
            'handlers': ['console'],
            'level': 'DEBUG',
            'propagate': False, # this tells logger to send logging message
                                # to its parent (will send if set to True)
        },
        'django.db': {
            # # django also has database level logging
            'handlers': ['console'],
            'level': 'DEBUG',
            'propagate': False,
        },
    },
}
