Tastypie return data from DELETE requests?

Question

I have a simple resource that I would like perform a DELETE. On success I would like to get the ID of the object that was deleted. As per the docs, always_return_data

you do not need to return the deleted object. You can just update the bundle.obj in obj_delete and then return it to the delete_detail. I am using custom resources and a middleware to run the api, but if you skip on the meta-model thingy it is pretty straight forward.

def obj_delete(self,bundle, **kwargs):
    self.load_user_obj(bundle.request)
    l_instanceId = kwargs['pk']
    try:
        #load the instance
        self.m_objMetaModel.load(l_instanceId,True)

        #do the manipulation on it
        self.m_objMetaModel.REST_IMPL.delete()

        #get an instance back. In my case in the delete I
        #am creating a virtual instance- just an object that 
        #fits the other parts of the api
        bundle.obj = self.m_objMetaModel.instance

        #load the bundle manually
        self.m_objMetaModel.REST_IMPL.reload_data(bundle.obj,bundle.data)

        return bundle
    except Exception as e:
        print(e)

def delete_detail(self, request, **kwargs):
    bundle = Bundle(request=request)

    try:
        # perform the operation returning the recreated bundle
        deleted_bundle = self.obj_delete(bundle=bundle,
                                **self.remove_api_resource_names(kwargs))

        # keep the meta configuration, just to avoid surprises later
        if not self._meta.always_return_data:
            return http.HttpNoContent()
        else:
            #update the bundle, you can skip on the dehydrate if you 
            #are loading the bundle data manually
            deleted_bundle = self.full_dehydrate(deleted_bundle)
            deleted_bundle = self.alter_detail_data_to_serialize(request, 
                                                               deleted_bundle)
            return self.create_response(request, deleted_bundle)
    except NotFound:
            return http.HttpNotFound()
