Objects cannot be stored in session from Django 1.6 or above. If you don't want to change the behavior of the cookie value(of a object), you can add a dictionary there. This can be used for non database objects like class object etc.

from django.core.serializers.json import DjangoJSONEncoder
import json     
card_dict = card.__dict__
card_dict .pop('_state', None) #Pop which are not json serialize
card_dict = json.dumps(card_dict , cls=DjangoJSONEncoder)
request.session['card'] = card_dict
