您收到错误消息是因为'project.logging.SpecialFilter'不存在，您必须在Django项目中创建此类/方法。

在/目录中创建模块'mylogging.py'，其中包含settings.py和wsgi.py和url.py。一个示例SpecialFilter实现：-

    import logging
from random import choice

class SpecialFilter(logging.Filter):
    # """
    # This is a filter which injects contextual information into the log.
    # 
    # Rather than use actual contextual information, we just use random
    # data in this demo.
    # """

    USERS = ['jim', 'fred', 'sheila']
    IPS = ['123.231.231.123', '127.0.0.1', '192.168.0.1']

    def filter(self, record):

        record.ip = choice(SpecialFilter.IPS)
        record.user = choice(SpecialFilter.USERS)
        return True

还修复您的setting.py以正确指向新的SpecialFilter模块位置。

    'filters': {
    'special': {
        '()': '<your_project_name>.mylogging.SpecialFilter',
        # '()': 'django.utils.log.RequireDebugTrue',
        # 'foo': 'bar',
    },

syncdb时记录错误
