我创建了一个 AbstractUser 模型来向标准用户模型添加一些额外的字段。

我认为一切都设置正确，但是当我登录时，我收到此错误：

unbound method save() must be called with UserProfile instance as first argument (got nothing instead)

这是我的帐户/models.py

from django.db import models
from django.conf import settings
from django.contrib.auth.models import UserManager, AbstractUser


class UserProfile(AbstractUser):
    mobile = models.CharField(max_length=20, blank=True)
    homephone = models.CharField(max_length=20, blank=True)
    updated = models.DateTimeField(blank=True, null=True)    

    objects = UserManager()

在我的设置中，我有：

AUTH_USER_MODEL = 'accounts.UserProfile'

我的身份验证中间件：

from django.conf import settings
from django.contrib.auth import authenticate, login
from django.contrib.auth.models import User
from accounts.models import UserProfile


#Authentication Middleware using a external cookie named AUTHENTICATION
class CookieMiddleware(object):

    def process_request(self, request):
        #if not hasattr(request, 'userprofile'):
        #   raise ImproperlyConfigured()
        if "AUTHENTICATION" not in request.COOKIES:
            #Cookie not found - do nothing
            return

        #Token found - first check if the user is allready is logged in
        if request.user.is_authenticated():
            return

        #Not logged in, then send to RemoteUserBackend.py    
        token = request.COOKIES["AUTHENTICATION"]

        #Return if the cookie length is 0
        if len(token) == 0:
            return

        UserProfile = authenticate(token=token)
        request.UserProfile = UserProfile

        if request.UserProfile:
            login(request, request.UserProfile)

我的 RemoteUserBackend.py 用于登录外部用户：

from django.conf import settings
from django.contrib.auth import authenticate, login
from django.contrib.auth.models import User
from base64 import b64decode
from hashlib import sha1
from urllib import unquote
from sitetasks import tasks
from accounts.models import UserProfile


class Backend( object ):
        def authenticate(self, username=None, password=None, token=None):

            #Unescape token
            unescaped_token = unquote(token)

            #Decode token
            decoded_token = unescaped_token.decode('base64')

            #Split the token into tree variable
            secret, hashstring, userID = decoded_token.split('-', 2)

            #Secret needs to bee in lower to match shared secret
            secret_lower = secret.lower()

            #Make string of SHARED_SECRET, hashstring, userID
            check_string = "%s%s%s" % (settings.SHARED_SECRET, hashstring, userID)

            #sha1 the string
            sha1_check_string = sha1(check_string)

            #Check if the SHARED_SECRET is matching cookie secret
            cookie_valid = sha1_check_string.hexdigest() == secret_lower

            if cookie_valid:
                try:
                    userprofile = UserProfile.objects.get(username=userID)

                    #The user exist, then update the user

                    #Make celery worker update user asynchronous
                    tasks.user_update.delay(user_id=userID)

                except UserProfile.DoesNotExist:
                    # Create a new user

                    userprofile = UserProfile(username=userID)
                    userprofile.is_staff = False
                    userprofile.is_superuser = False



                    userprofile.save() #Save the user

                    #Make celery worker update user asynchronous
                    tasks.user_update.delay(user_id=userID)


                return UserProfile
            return None

        def get_user(self, user_id):
            try:
                return UserProfile.objects.get(pk=user_id)
            except UserProfile.DoesNotExist:
                return None

我得到的错误的回溯是这样的：

有人看到我在这里做错了什么吗？

您的后端authenticate()方法返回UserProfile（类）而不是userprofile（属于用户的该类的实例）。

尽管中间件实际上并没有什么问题，但如果您保持相同的命名约定（这是普通的 Python 命名约定）并引用request.userprofile而不是request.UserProfile.
