django 日志无法设置 maxBytes

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

这是异常(exception)。

Traceback (most recent call last):
  File "/home/moon/.env/envpy3/lib/python3.5/site-packages/django/utils/autoreload.py", line 225, in wrapper
    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“maxBytes”参数，它会引发异常。

    'disable_existing_loggers': False,
    'formatters': {

        },

    },

        },
        '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hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

最佳答案

maxBytes 是 RotatingFileHandler 的属性，而不是 FileHandler 。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，包是 logging.handlers 。
