从Django升级到1.9时，“WSGIRequest”对象没有属性“session”

Question

类似于这个问题'WSGIRequest' object has no attribute 'session'

但是我的中间件类的顺序是正确的。

INSTALLED_APPS = [
    'django.contrib.sessions',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'membership',
    'treebeard',
    'haystack',
    'reversion',
]

MIDDLEWARE = [
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

我正在重定向到登录

url(r'^$',  RedirectView.as_view(url='login/')),
url(r'^login/$', 'membership.views.loginView', name='login'),

然后

def loginView(request):
    a = request.session

抛出错误

MIDDLEWARE是1.10中的新设置，它将替换旧的MIDDLEWARE_CLASSES。

由于您当前使用的是1.9，Django无法识别MIDDLEWARE设置。您应该改用MIDDLEWARE_CLASSES设置：

MIDDLEWARE_CLASSES = [
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
