文件浏览器配置错误：未定义名称“设置”

Question

我尝试激活 django-filebrowser-no-grappelli，并使用 this indications 进行配置。

然后我用这个更新了setting.py：

但是当我启动服务器时出现这个错误：

.... 文件 "/var/www/html/dev/miosito/django/beautifulsite_v0.1/djangosite/djangosite/settings.py", 第 168 行，在 DIRECTORY = getattr(settings, "FILEBROWSER_DIRECTORY", 'uploads/') NameError: name 'settings' is not defined

老实说，我不清楚是否必须在 settings.py 的末尾或其他部分复制所有字符串。我觉得这是问题所在，我很困惑......

文档向您展示他们如何从您的配置中找到设置和/或各自的默认值是什么。如果您想更新项目的设置文件以更改部分或全部默认值，您应该执行类似的操作

# settings.py

# FileBrowser settings
FILEBROWSER_DIRECTORY = 'uploads/'
FILEBROWSER_EXTENSIONS = {
    'Image': ['.jpg','.jpeg','.gif','.png','.tif','.tiff'],
    'Document': ['.pdf','.doc','.rtf','.txt','.xls','.csv'],
    'Video': ['.mov','.wmv','.mpeg','.mpg','.avi','.rm'],
    'Audio': ['.mp3','.mp4','.wav','.aiff','.midi','.m4p']
}
