django serializers to json - custom json output format

Question

I am quite new to django and recently I have a requirement of a JSON output, for which I use the following django code:

data = serializers.serialize(\"json\", My         


        

Answer 1

You can add 'fields' parameter to the serialize-function, like this:

data = serializers.serialize('xml', SomeModel.objects.all(), fields=('name','size'))

See: https://docs.djangoproject.com/en/dev/topics/serialization/

EDIT 1:

You can customize the serializer to get only the fields you specify.

From Override Django Object Serializer to get rid of specified model:

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)
