Question

我收到此错误＆＃39; WSGIRequest＆＃39;对象在manage.py runserver上没有属性＆＃39; session＆＃39; 。当我尝试从request.session中检索会话dict时。

对此项目的搜索说我需要放入＆＃39; django.contrib.sessions.middleware.SessionMiddleware＆＃39;在MIDDLEWARE设置之上。然而，这似乎不起作用。

我的settings.py：

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

您使用的是Django 1.9版; MIDDLEWARE设置仅在1.10版中引入。对于像您这样的早期版本，您应该使用MIDDLEWARE_CLASSES - 或升级到1.10。
