AttributeError：“WSGIRequest”对象没有属性“user”

Question

我正在运行我的 Django 代码，但收到此错误

AttributeError: 'WSGIRequest' object has no attribute 'user'

我的Django版本是1.8.2，这是我的setting.py中间件类

MIDDLEWARE_CLASSES = (

'khxia.middlewares.PeeweeConnectionMiddleware',

'django.contrib.sessions.middleware.SessionMiddleware',
'subdomains.middleware.SubdomainURLRoutingMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'django.middleware.security.SecurityMiddleware',

'referral.middlewares.ReferralRecordMiddleware',
'common.middlewares.ExceptionMiddleware',
)

这是我的完整回溯

Traceback (most recent call last):
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/wsgiref/handlers.py", line 85, in run

  File "/Users/motion/Documents/GitHub/khx2/khxia/common/shortcuts.py", line 40, in render
    if request.user.is_authenticated():
AttributeError: 'WSGIRequest' object has no attribute 'user'

views.py第68行是：

def server_error(request):
    res = render(request, 'home/500.html')
    res.status_code = 500
    return res

渲染函数如下所示：

def render(request, template_name, dictionary=None):
    """

    :param request: Django request object
    :param template_name: template name
    :param dictionary: parameter of dictionary
    """
    dictionary = dictionary or {}
    dictionary.update({
        'settings': settings,
        'DEBUG': settings.DEBUG,
        'server_time': int(time.time()),
    })

    if request.user.is_authenticated():
        dictionary['user_hashid'] = hashid.encode(request.user.id)

    temp = template_name.replace('.html', '').split('/')
    if len(temp) == 1:
        module = 'v{name}'.format(name=temp[0].capitalize())
    else:
        name = ''.join([t.capitalize() for t in temp])
        module = 'v{name}'.format(name=name)
    dictionary['load_module'] = module
    return django_render(
        request,
        template_name,
        dictionary
    )

Answer 1

这是因为您放置中间件的顺序。

request.user 由 AuthenticationMiddleware 添加到 WSGI 请求对象。

地点

'khxia.middlewares.PeeweeConnectionMiddleware',

此中间件位于 AuthenticationMiddleware 之后，或作为最后一个中间件

如果您使用 IntelliJ 并使缓存无效或删除 .iml 文件，请在项目文件夹上点击

right-click

，然后选择

Open Module Settings

。在打开的窗口中，选择

Facets

下的

Project Settings

，单击

+

，然后选择

Django

。更新

Django project root

和

Settings

位置；如果操作正确，

manage.py

和

migrations

将自动定位。请务必检查

Project

设置是否正确

Python SDK

，以及

Modules->Dependencies

是否匹配

Module SDK

。
