I just came across this as I was having the same problem. I also solved this with a custom serializer, tried the "EDIT 1" method but it didn't work too well as it stripped away all the goodies that the django JSON encoder already did (decimal, date serialization), which you can rewrite it yourself but why bother. I think a much less intrusive way is to inherit the JSON serializer directly like this.

from django.core.serializers.json import Serializer
from django.utils.encoding import smart_text    

class MyModelSerializer(Serializer):
def get_dump_object(self, obj):
    self._current['id'] = smart_text(obj._get_pk_val(), strings_only=True)
    return self._current

so the main culprit that writes the fields and model thing is at the parent level python serializer and this way, you also automatically get the fields filtering that's already built into django's JSON serializer. Call it like this

serializer = MyModelSerializer()
data = serializer.serialize(<queryset>, <optional>fields=('field1', 'field2'))
