How to add extra object to tasty pie return json in python django

In Django project i get two objects when i receive the JSON response

data.meta and data.objects

This is my Resource

class MyResource(ModelResource):
    def dehydrate(self, bundle):
        bundle.data["absolute_url"] = bundle.obj.get_absolute_url()
        bundle.data['myfields'] = MyDataFields
        return bundle
    class Meta:

        queryset = MyData.objects.all()
        resource_name = 'weather'
        serializer = Serializer(formats=['json'])
        ordering = MyDataFields

now i want to other field in json like

data.myfields

but if i do the above way then that field is added to every object like

data.objects.myfields

how can i do data.myfields
