Django-使用mongoengine DB进行身份验证

Question

我想使用mongoengine db在Django项目中处理身份验证。

我尝试了一些有关此问题的示例，这些问题已在旧问题中得到解答，但并未运行。我正在使用Django
1.6和mongoengine。一切都已安装，运行，并且我可以创建文档并将其保存到Mongoengine DB。

我正在追踪http://mongoengine-
odm.readthedocs.org/en/latest/django.html

我得到以下错误：

当我跑步时：

>>> from django.contrib.auth.models import User
>>> user = User.objects.create_user('john', '[e-mail]', 'johnpassword')

我得到这个：

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/REBORN/reb_env/local/lib/python2.7/site-packages/django/db/models/manager.py", line 273, in __get__
    self.model._meta.object_name, self.model._meta.swapped
AttributeError: Manager isn't available; User has been swapped for 'mongo_auth.MongoUser'
>>>

我真的不明白两件事：

-是否必须创建并定义将存储用户的数据库，否则将自动创建用户？

-经理是什么？我还没有定义任何经理的东西

在开始的时候，我认为寄存器已保存在数据库中。调用了“ mongo_auth.MongoUser”，但没有将其保存在任何地方。

这是模型：

# Create your models here.
from mongoengine import *

class Profile(Document):
    email = StringField(required=True)
    first_name = StringField(max_length=50)
    last_name = StringField(max_length=50)

class auth_user(Document):
    username = StringField(max_length=50)
    email = StringField(max_length=50)
    password = StringField(max_length=50)

settings.py已按照手册所述正确配置。

编辑@cestDiego：

我的设置完全相同，我注意到了Db后端，因为它创建了一个我不感兴趣的数据库，因为我使用mongo
…无论如何，我现在使用的是mongoengine.django.auth import用户，但是当我尝试时创建一个用户，它返回我：

>>> user = User.objects.create_user('john', '[e-mail]', 'johnpassword')
Traceback (most recent call last):
  File "<console>", line 1, in <module>
AttributeError: 'QuerySet' object has no attribute 'create_user'

也许我们正在自定义身份验证，这就是为什么不起作用，不知道的原因。你也有这个问题吗？

第二编辑：

我正在阅读，配置正确的设置后，我们必须使用Django的auth，就像我们所做的一样。

然后必须从django.contrib.auth导入import
authenticate并使用Django文档中提供的authenticate，希望对您有所帮助。

from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
from game.models import *
from mongoengine import *
from models import User
from django.contrib.auth import authenticate

def login(request):
        user = authenticate(username='john', password='secret')
        if user is not None:
            # the password verified for the user
            if user.is_active:
                print("User is valid, active and authenticated")
            else:
                print("The password is valid, but the account has been disabled!")
        else:
            # the authentication system was unable to verify the username and password
            print("The username and password were incorrect.")

在Django 1.6中…

我的settings.py看起来像这样：

和我的views.py看起来像：

from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
from game.models import *  
from mongoengine import *
#from django.contrib.auth import authenticate
from mongoengine.django.auth import User

def login(request):
    connect('reborn')
    from django.contrib.auth import login
    from mongoengine.django.auth import User
    from mongoengine.queryset import DoesNotExist
    from django.contrib import messages
    try:
        user = User.objects.get(username='bob')#request.POST['username'])
        if user.check_password('bobpass'):#request.POST['password']):
            user.backend = 'mongoengine.django.auth.MongoEngineBackend'
            print login(request, user)
            request.session.set_expiry(60 * 60 * 1) # 1 hour timeout
            print "return"
            return HttpResponse("LOGUEJAT")#redirect('index')
        else:
            print "malament"
            messages.add_message(request,messages.ERROR,u"Incorrect login name or password !")
    except DoesNotExist:
        messages.add_message(request,messages.ERROR,u"Incorrect login name or password !")
    return render(request, 'login.html', {})

def logout(request):#NOT TESTED
    from django.contrib.auth import logout
    logout(request)
    return redirect('login')

def createuser(request): 
    connect('reborn')
    User.create_user('boba','bobpass','[e-mail]')
    return HttpResponse("SAVED")

现在，用户对象保存在数据库中，如下所示：

{
    "_id" : ObjectId("53465fa60f04c6552ab77475"),
    "_cls" : "User",
    "username" : "boba",
    "email" : "[e-mail]",
    "password" : "pbkdf2_sha256$12000$ZYbCHP1K1kDE$Y4LnGTdKhh1irJVktWo1QZX6AlEFn+1daTEvQAMMehA=",

    "user_permissions" : [ ]
}
