在设置文件中，在“logger”中的“django”之后添加“django.template”，如下所示：

'loggers': {
    'django': {
        'handlers': ['file'],
        'level': 'DEBUG',
        'propagate': True,
    },
    'django.template': {
        'handlers': ['file'],
        'level': 'INFO',
        'propagate': True,
    },
}

这有什么用？谢谢，这帮帮忙！

'loggers': {
    'django': {
        'handlers': ['file'],
        'level': 'DEBUG',
        'propagate': True,
    },
    'django.template': {
        'handlers': ['file'],
        'level': 'INFO',
        'propagate': True,
    },
}
