Serialize the @property methods in a Python class

Question

Is there a way to have any @property definitions passed through to a json serializer when serializing a Django model class?

example:

class FooBar(obj         


        

Answer 1

The solution worked well that is proposed by M. Rafay Aleem and Wtower, but it's duplicated lot of code. Here is an improvment:

from django.core.serializers.base import Serializer as BaseSerializer
from django.core.serializers.python import Serializer as PythonSerializer
from django.core.serializers.json import Serializer as JsonSerializer

class ExtBaseSerializer(BaseSerializer):

    def serialize_property(self, obj):
        model = type(obj)
        for field in self.selected_fields:
            if hasattr(model, field) and type(getattr(model, field)) == property:
                self.handle_prop(obj, field)

    def handle_prop(self, obj, field):
        self._current[field] = getattr(obj, field)

    def end_object(self, obj):
        self.serialize_property(obj)

        super(ExtBaseSerializer, self).end_object(obj)


class ExtPythonSerializer(ExtBaseSerializer, PythonSerializer):
    pass


class ExtJsonSerializer(ExtPythonSerializer, JsonSerializer):
    pass

How to use it:

ExtJsonSerializer().serialize(MyModel.objects.all(), fields=['field_name_1', 'property_1' ...])
