Authentification - Django - Query mongoengine.django.auth.UserManager

[christophe de saint leger]

I all, 

i don't know if this problem is from mongoengine ( link width Django "Authentification" ) but i think there are relation .

I have created a model ( CreaviUser )  who derivate from User model. 

Each request must be authentificated, by a middleware ( this is a simple test is_authenticated() ) , but when i refresh or navigate on my website, sometimes i am redirected to my login form . And if i refresh again , i return on my website ! 

I checked the logs of mongodb : 

Wed May 22 16:09:25.632 [conn1036] query creaboard.user query: { _id: ObjectId('5194922d88a53d4da3a2f6ce'), _cls: { $in: [ "User" ] } } ntoreturn:1 ntoskip:0 nscanned:0 keyUpdates:0 locks(micros) r:83 nreturned:0 reslen:20 0ms
Wed May 22 16:09:25.643 [conn1033] query creaboard.user query: { _id: ObjectId('5194922d88a53d4da3a2f6ce'), _cls: { $in: [ "User", "User.CreaviUser" ] } } ntoreturn:1 ntoskip:0 nscanned:3 keyUpdates:0 locks(micros) r:141 nreturned:1 reslen:548 0ms

Sometimes the query is different 

ok   ->  $in: [ "User", "User.CreaviUser" ]

Fail ->  $in: [ "User" ]

Have you an idea of the problem?

My CreaviUser Model: 

# -*- coding:utf-8 -*-
from mongoengine import *
from mongoengine.django.auth import User,UserManager
import datetime

class CreaviUser(User):
    """
    Surcharge de l'utilisateur standard
    """
    username           = StringField(max_length=50,required=True)
    is_admin           = BooleanField(default=False)
    nocentre           = IntField(required=True)
    centre             = StringField(max_length=50, required=True)
    adresse            = StringField(max_length=100, required=True)
    adresse2           = StringField(max_length=100, required=False)
    cp                 = StringField(max_length=5, required=True)
    ville              = StringField(max_length=50, required=True)
    pays               = StringField(max_length=50,default='FRANCE',required=True)
    telephone          = StringField(max_length=30, required=False)
    fax                = StringField(max_length=30, required=False)
    site               = URLField()
    mail               = EmailField()
    date               = DateTimeField(default=datetime.datetime.now, required=True)
    # Use UserManager to get the create_user method, etc.
    objects = UserManager()

Ok , when i test with a single process (uwsgi) , it work fine ...
And i have tested with Django 1.4 with multi process ... it work fine too ...

i'm lost :(

I do not understand why sometimes the application does not use the model derived.
Yet it is referenced in the _cls field.

Any idea?

Without producing a reproducible test case, its hard to determine the cause.  

What checks that the user is logged in?  Child classes should return when queried from the parent class.

Also what version of MongoEngine is this?

I use mongoengine : mongoengine==0.8.1 and Django 1.5.1

The problem appear only when i use multi process uwsgi.

i use a middleware to check if my user is logged :

from django.http import HttpResponse,HttpResponseRedirect

class AuthenticationMiddleware(object):
   
    _LOGIN_PATH = "/accounts/login_view/"
   
    def process_request(self, request):

        if (request.path != self._LOGIN_PATH) and not request.is_ajax():
            if not request.user.is_authenticated():
                return HttpResponseRedirect( self._LOGIN_PATH+'?next=%s' % request.path)
        return None

My child class only serves to enrich the model User.

I tested uwsgi multi threaded mode, with a single process, and it works perfectly.

Same with gunicorn.

There must have global data is not shared between processes.

so I think mongoengine is not responsible for this bug ..

Sorry for the inconvenience.

good day,
