【问题描述】：

很抱歉问这个问题

我正在尝试设置日志以测试我的代码； Django pass variable into template

我按照https://docs.djangoproject.com/en/2.1/topics/logging/中的示例进行操作

这里是他们使用的代码

LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'handlers': {
    'file': {
        'level': 'DEBUG',
        'class': 'logging.FileHandler',
        'filename': r'C:\Users\Sk\Desktop\project\FrounterWeb\FrounterWeb\logs',
    },
},
'loggers': {
    'django': {
        'handlers': ['file'],
        'level': 'DEBUG',
        'propagate': True,
    },
},
}

但我遇到了这个问题，复制粘贴，我得到的答案是这个；

    handler = self.configure_handler(handlers[name])

    return open(self.baseFilename, self.mode, encoding=self.encoding)
PermissionError: [Errno 13] Permission denied: 'C:\\Users\\Sk\\Desktop\\project\\FrounterWeb\\FrounterWeb\\logs'

The above exception was the direct cause of the following exception:

  File "manage.py", line 15, in <module>
    execute_from_command_line(sys.argv)
  File "C:\Users\Sk\AppData\Local\Programs\Python\Python37\lib\site-packages\django\core\management\__init__.py", line 381, in execute_from_command_line

  File "C:\Users\Sk\AppData\Local\Programs\Python\Python37\lib\logging\config.py", line 563, in configure
    '%r' % name) from e
ValueError: Unable to configure handler 'files'

我相信字典有这个问题，所以我删除了 'File':{} & 'django':{} 字典，我收到了另一个问题

新代码：

    LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
    'file': {
        'level': 'DEBUG',
        'class': 'logging.FileHandler',
        'filename': r'C:\Users\Sk\Desktop\project\FrounterWeb\FrounterWeb\logs',
    },
},
        'loggers': {
        'django': {
        'handlers': ['file'],
        'level': 'DEBUG',
        'propagate': True,
         },
         },
         }

这是个问题；

这个问题意味着它可以读取自己的库

很抱歉给你添麻烦了，但请帮帮我，我真的不知道该怎么办，因为 Django 告诉我在库中自己的构建有问题（我认为）

【问题讨论】：

您是否将/path/to/django/debug.log 替换为实际有效的路径？如果没有，您将遇到这些问题。将其替换为 r'C:\Users\Sk\Desktop\django.log' 之类的路径或其他位置（确保该目录首先存在，并且您有权在其中创建文件）。桌面、文档和下载文件夹是不错的选择。
/path/to/django/debug.log;不，因为我尝试使用我的文件夹时不知道要替换什么，但它没有用。后来真的不知道怎么办了，不知道用哪个。
在您拥有settings.py 的同一文件夹中创建一个名为logs 的目录，然后将/path/to/django/debug.log 替换为该目录的完整路径，例如r'C:\Users\Sk\Desktop\FrounterWeb\logs\django.log'
burhan khalid，谢谢你给我指路，但它没有用，有这个错误 intsead； SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape 我为这个问题道歉
布尔汉·哈立德；我找到了语法错误的答案，我没有在路径前添加“r”。我觉得好傻

【解决方案1】：

您需要将formatter 添加到您的日志记录中：

LOGGING = {
'formatters': {
    'verbose': {
         'format': '{levelname} {message}',
         'style': '{',
    },
},
# Rest of the Logging Config
}

【讨论】：

对不起，我不太明白，也许你可以解释一下，但我想：" 'format': {levelname} 'style': '{'," 是自定义日志记录吗？

【解决方案2】：

答案很简单，就像 Burhan Khalid 所说的那样，网站的日志路径没有绑定文件的日志路径。

我所做的只是将它添加到我的处理程序中

'filename': 'zigview\logging_files\debug.log',

并且正在工作

我觉得好尴尬，犯了这么简单的错误
