关于Django django.template.base.VariableDoesNotExist

运行环境

pycharm 2017.1
Django 2.0.1
python 3.6.1

在Django网页项目中添加logger

在settings.py添加logging对应代码：

LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'formatters': {
        'standard': {
            'format': '%(asctime)s [%(threadName)s:%(thread)d] [%(name)s:%(lineno)d] [%(module)s:%(funcName)s] [%(levelname)s]- %(message)s'}  #日志格式
    },
    'filters': {
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'class': 'django.utils.log.AdminEmailHandler',
            'include_html': True,
            },
        'default': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': 'log/all.log',     #日志输出文件
            'maxBytes': 1024*1024*5,                  #文件大小
            'backupCount': 5,                         #备份份数
            'formatter':'standard',                   #使用哪种formatters日志格式
        },
        'error': {
            'level':'ERROR',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': 'log/error.log',
            'maxBytes':1024*1024*5,
            'backupCount': 5,
            'formatter':'standard',
            },
        'console':{
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'standard'
        },
        'request_handler': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': 'log/script.log',
            'maxBytes': 1024*1024*5,
            'backupCount': 5,
            'formatter':'standard',
            },
        'scprits_handler': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename':'log/script.log',
            'maxBytes': 1024*1024*5,
            'backupCount': 5,
            'formatter':'standard',
            }
    },
    'loggers': {
        'django': {
            'handlers': ['default', 'console'],
            'level': 'DEBUG',
            'propagate': False
        },
        'django.request': {
            'handlers': ['request_handler'],
            'level': 'DEBUG',
            'propagate': False,
            },
        'scripts': {
            'handlers': ['scprits_handler'],
            'level': 'INFO',
            'propagate': False
        },
        'blog.views': {
            'handlers': ['default', 'error'],
            'level': 'DEBUG',
            'propagate': True
        },
    }
}

在views.py中引用代码：

import logging
logger=logging.getLogger('blog.views')#blog为对应app名称

运行网页发生如下错误(部分)：

查阅之后发现此exception应为Django的一个漏洞：

• Django官网
• Github

很遗憾地说现在暂时找不到有效的解决办法
