Question

我在我的应用程序中添加了一个中间件django-user-agents，用于获取用户代理信息，现在我的应用程序无法启动。我按照github页面上提到的所有步骤进行了操作：django_user_agents 但是不能让这件事起作用。

这是堆栈跟踪：

    mw_instance = middleware(handler)

如果有人想出来的话会非常有用。

如果我错过了某些内容/某些内容不明确，请随意提出问题。

感谢期待!! ：）

您尝试使用的中间件似乎与Django版本＆gt; = 1.10不兼容。 GitHub已经存在一个未解决的问题：

https://github.com/selwin/django-user_agents/issues/13

他们现在的解决方法是尽可能使用旧式MIDDLEWARE_CLASSES设置而不是MIDDLEWARE设置。

相关拉取请求（https://github.com/selwin/django-user_agents/pull/17）的另一个选项是创建扩展其他中间件的自己的中间件：

from django.utils.deprecation import MiddlewareMixin
from django_user_agents.middleware import UserAgentMiddleware

class CustomUserAgentMiddleware(MiddlewareMixin, UserAgentMiddleware):
    pass

然后在你的settings.py中：

MIDDLEWARE = [
    # other middlewares...
    'path.to.your.own.file.CustomUserAgentMiddleware',
]

Django - 无法添加中间件
