<Django object > is not JSON serializable

I have the following code for serializing the queryset: def render_to_response(self, context, **response_kwargs): return HttpResponse(json.simplejson.dumps(list(self.get_queryset())), mimetype="application/json") And following is my get_quersety() [{'product': <Product: hederello ()>, u'_id': u'9802', u'_source': {u'code': u'23981', u'facilities': [{u'facility': {u'name': {u'fr': u'G\xe9n\xe9ral', u'en': u'General'}, u'value': {u'fr': [u'bar', u'r\xe9ception ouverte 24h/24', u'chambres non-fumeurs', u'chambres familiales',.........]}] Which I need to serialize. But it says not able to serialize the <Product: hederello ()>. Because the list is composed of both django objects and dicts. Any ideas?
simplejson and json don't work with django objects well. Django's built-in serializers can only serialize querysets filled with django objects: data = serializers.serialize('json', self.get_queryset()) return HttpResponse(data, content_type="application/json") In your case, self.get_queryset() contains a mix of django objects and dicts inside. One option is to get rid of model instances in the self.get_queryset() and replace them with dicts using model_to_dict: from django.forms.models import model_to_dict data = self.get_queryset() for item in data: item['product'] = model_to_dict(item['product']) return HttpResponse(json.simplejson.dumps(data), mimetype="application/json")
