MongoDB with Django Rest Elasticsearch?

Question

Following the Basic Usage example at http://django-rest-elasticsearch.readthedocs.io/en/latest/

from app.serializers import BlogSerializer
from app.models import Blog
from rest_framework_elasticsearch import (es_views, es_client, es_pagination, es_filters)
from .search_indexes import BlogIndex

class BlogView(es_views.ListElasticAPIView):
es_client = es_client
es_model = BlogIndex
es_pagination_class = es_pagination.ElasticLimitOffsetPagination
es_filter_backends = (
    es_filters.ElasticFieldsFilter,
    es_filters.ElasticFieldsRangeFilter,
    es_filters.ElasticSearchFilter,
    es_filters.ElasticOrderingFilter,
)
es_ordering = 'created_at'
es_filter_fields = (
    es_filters.ESFieldFilter('tag', 'tags'),
)
es_range_filter_fields = (
    es_filters.ESFieldFilter('created_at', 'created_at'),
)
es_search_fields = (
    'tags',
    'title',
)

Gives me the stacktrace:

`Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x10de071e0>

I am using MongoDB for persistence and this is almost certainly related.

Has anyone successfully used Django Rest Framework with Mongo and Elasticsearch that would point me toward a solution or packages that can handle Django-REST, Mongo and Elasticsearch? Or has anyone encountered this problem and have a workaround?

Thank you in advance!

In case you are still wondering, you can use haystack. It is library that integrates Django with Elasticsearch.
