django object is not JSON serializable error after upgrading django to 1.6.5

Question

I have a django app which was running on 1.4.2 version and working completely fine, but recently i updated it to django 1.6.5 and facing some wierd

Answer 1

Django 1.6 changed the serializer from pickle to json. pickle can serialize things that json can't.

You can change the value of SESSION_SERIALIZER in your settings.py to get back the behaviour from Django before version 1.6.

SESSION_SERIALIZER = 'django.contrib.sessions.serializers.PickleSerializer'

You might want to read about session serialization in the documentation.
