Override Django Object Serializer to get rid of specified model - django

Question

I need to convert a Django Queryset Object into a Json string. The built in Django Serialization library works great. Although it specifies the name of the Model from where it was created. Since I don't need this, how do I get rid of it? What else do I need to override to be able to use the overridden end_object method below?
class Serializer(PythonSerializer):
def end_object(self, obj):
self.objects.append({
"model" : smart_unicode(obj._meta), # <-- I want to remove this
"pk" : smart_unicode(obj._get_pk_val(), strings_only=True),
"fields" : fields
})
self._current = None

Answer 1

Sorry I had totally forgot about this question. This is how I ended up solving it (with thanks to FunkyBob on #django):
from django.core.serializers.python import Serializer
class MySerialiser(Serializer):
def end_object( self, obj ):
self._current['id'] = obj._get_pk_val()
self.objects.append( self._current )
# views.py
serializer = MySerialiser()
data = serializer.serialize(some_qs)

Here's a serializer that removes all metadata (pk, models) from the serialized output, and moves the fields up to the top-level of each object. Tested in django 1.5
from django.core.serializers import json
class CleanSerializer(json.Serializer):
def get_dump_object(self, obj):
return self._current
Serializer = CleanSerializer
Edit:
In migrating my app to an older version of django (precipitated by a change in hosting provider), the above serializer stopped working. Below is a serializer that handles the referenced versions:
import logging
import django
from django.core.serializers import json
from django.utils.encoding import smart_unicode
class CleanSerializer148(json.Serializer):
def end_object(self, obj):
current = self._current
current.update({'pk': smart_unicode(obj._get_pk_val(),
strings_only=True)})
self.objects.append(current)
self._current = None
class CleanSerializer151(json.Serializer):
def get_dump_object(self, obj):
self._current['pk'] = obj.pk
return self._current
if django.get_version() == '1.4.8':
CleanSerializer = CleanSerializer148
else:
CleanSerializer = CleanSerializer151
Serializer = CleanSerializer

Override JSON serializer class:
from django.core.serializers.json import Serializer, DjangoJSONEncoder
from django.utils import simplejson
class MySerializer(Serializer):
"""
Convert QuerySets to JSONS, overrided to remove "model" from JSON
"""
def end_serialization(self):
# little hack
cleaned_objects = []
for obj in self.objects:
del obj['model']
cleaned_objects.append(obj)
simplejson.dump(cleaned_objects, self.stream, cls=DjangoJSONEncoder, **self.options)
In the view:
JSONSerializer = MySerializer
jS = JSONSerializer()
