Question

我无法将maxBytes设置为记录文件。我的django版本是2.0.3， Python 3.5.2 记录0.5.1.2

这是例外。

Traceback (most recent call last):

    fn(*args, **kwargs)

    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'file_database': __init__() got an unexpected keyword argument 'maxBytes'

这是我的settings.py。如果我添加＆＃34; maxBytes＆＃34; param，它会引发Exception。

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {

                      '(%(asctime)s; %(filename)s:%(lineno)d)',
        },
        'simple': {
            'format': '%(levelname)s %(message)s'
        },
    },
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': os.path.join(BASE_DIR, 'logs/debug.log'),
        },
        'file_database': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': os.path.join(BASE_DIR, 'logs/database.log'),
            'maxBytes': 1024 * 1024 * 10,  # 10 MB
        },

    },
    'loggers': {      
        'django.db.backends': {
            'handlers': ['file_database'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

非常感谢你好，呵呵呵呵呵呵呵呵呵

maxBytes是RotatingFileHandler而非FileHandler的属性。您需要将日志记录配置修改为：

'file_database': {
    'level': 'DEBUG',
    'class': 'logging.handlers.RotatingFileHandler',  # Use RotatingFileHandler
    'filename': os.path.join(BASE_DIR, 'logs/database.log'),
    'maxBytes': 1024 * 1024 * 10,  # 10 MB
},

请注意，该软件包为logging.handlers。
