django-mongodb : retrieve an object giving error(s)

Question

I'm using the django_mongo_engine(0.4.0) as backed for django application.

an Instructor object is created using like

inst = Instructor.objects.create(
        email=request.POST.get('email').lower(),
        password = set_password(request.POST.get('password')),
        title=request.POST.get('title'),
        first_name=request.POST.get('first_name'),
        last_name=request.POST.get('last_name'))

and

request.session['inst_id'] = inst.id

in mongo shell this inst.id appears to be ObjectId(u'533c3b0c9b0dbb416e000000')

while in debug mode (pdb)

Instructor.objects.all()[0].id

will give id u'533c3b0c9b0dbb416e000000'

Error(s) when retrieving instructor object:

 Instructor.objects.get(id=request.session['inst_id'])

ValueError: invalid literal for int() with base 10: '533c40a99b0dbb42d9000000'

instructor2 = Instructor.objects.get(id=ObjectId(request.session['inst_id']))

TypeError: int() argument must be a string or a number, not 'ObjectId'

instructor3 = Instructor.objects.get(id=str(request.session['inst_id']))

ValueError: invalid literal for int() with base 10: '533c40a99b0dbb42d9000000'

Any clue ?
