如何在 Django 2.2 中使中间件对象可调用
How to make middleware object callable in Django 2.2
我正在尝试将 django/mezzanine 应用程序从 python 2.7 更新到 python 3.7。你能帮我修正下面的错误吗(CTypeError: 'CheckNewsDateStatus' object is not callable)?
好像这个class根本没用过；如果我 grep 通过所有代码，只有附加的 settings.py 和 middleware.py 匹配。它是在 django/mezzanine 中部分实现的，还是它使得整个 class 可以被删除？
我不知道代码是如何计划工作的，我也不知道这个功能是否已经被使用了......我不知道可调用对象应该如何在 settings.py-文件.
