python - Django - Auth with mongoengine DB

Question

I want to handle authentications in my Django project with my mongoengine db.

I tried a few examples about this stuff answered in old questions but it didn't run. I'm using Django 1.6 and mongoengine. Everything is installed, running and I can create and save documents to my Mongoengine DB.

I'm following http://mongoengine-odm.readthedocs.org/en/latest/django.html

And i get the following error:

When i run:

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

I get this:

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'
>>> 

I really don't understand 2 things:

-Do I must create and define the database where the users will be stored or they will be created automatically?

-What is Manager? I haven't defined any manager stuff

At the beggining i thought that the register was saved in a db. callled 'mongo_auth.MongoUser' but it didn't save it in nowhere.

Here is the models:

# 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)

The settings.py is properly configured as the manual says.

EDIT @cestDiego:

My settings are exactly the same, I've noticed about the Db backend because it creates me a database which am not interested because I use mongo...Anyway I'm ussing from mongoengine.django.auth import User now but when I try to create an User it returns me :

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

Maybe we are customizing the auth and that's why not work, no idea. Do you have this problem too ?

SECOND EDIT:

I was reading and we have to use Djangos auth, after configure the right settings, as both we have done.

Then must import the from django.contrib.auth import authenticate and use authenticate as it is provided in Django docs, hope to help ;D.

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.")

Hey I'm in the same situation as you are. As I can figure out you have these in the settings.py

AUTH_USER_MODEL = 'mongo_auth.MongoUser'
MONGOENGINE_USER_DOCUMENT = 'mongoengine.django.auth.User'

And this in the installed apps

'mongoengine.django.mongo_auth'

This means that now you are using the Mongoengine authentication method, The first line you are using imports the DJANGO authentication method, so there's the problem. You are not creating any databases in mongodb, but in the dummy one you have set up with the backend.dummy in the ORM of Django.

I don't know how to use mongoengine's auth method, if you figure it out please explain it to me too ;) I hope I clarified you a little about the problem we both face here. It's just a matter of reading more profoundly the docs.

EDIT: (1 minute after the answer) I found this in the documentation you linked to:

MongoEngine includes a Django authentication backend, which uses MongoDB. >The User model is a MongoEngine Document, but implements most of the >methods and attributes that the standard Django User model does - so the >two are moderately compatible.

so that means that in your case, swap the

from django.contrib.auth import User

to

from mongoengine.django.auth import User
