无法使用中间件将用户名添加到日志记录

username 和 project request 对象)。我不想补充 context

问题是我做不到 Django 添加 请求 或者是直的 用户名 项目 致 LogRecord

这是我的代码:

import threading
local = threading.local()

class LoggingRequestMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response
        # One-time configuration and initialization.

    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.
        setattr(local, 'request', request)
        response = self.get_response(request)

        # Code to be executed for each request/response after
        # the view is called.

        return response

设置.py

def add_username_to_log(record):
local = threading.local()
record.username = '-'
request = getattr(local,'request',None)
print(request)

return True

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'verbose': {
            'format': LOGGING_VERBOSE_FORMAT,
            'style': '{',
        },
    },
    'filters': {
        'context_filter': {
            '()': 'django.utils.log.CallbackFilter',
            'callback': add_username_to_log,
        },

    },
    'handlers': {
        'console': {
            'level': DEFAULT_LOG_LEVEL,
            'class': 'logging.StreamHandler',
            'formatter': 'verbose',
            'filters': ['context_filter'],
        },
        'file_main': {
            'level': DEFAULT_LOG_LEVEL,
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': os.path.join(LOG_PATH, 'main.log'),
            'maxBytes': DEFAULT_LOG_SIZE,
            'formatter': 'verbose',
            'filters': ['context_filter'],
            'backupCount': 0,
        },

    },
    'loggers': {
        '': {
            'handlers': ['file_main'],
            'level': DEFAULT_LOG_LEVEL,
            'propagate': False,
        },

    },
}

但是 请求 None . 你知道为什么吗?
