Articles are not indexed on django-haystack

[lucashelfs]

Hi, I've been struggling with this for the past few weeks. I'm not able to index aldryn-newsblog content to django-haystack. I'm using ElasticSearch and it is properly configured, I also tried to use a SimpleBackend and it didn't worked.

When I run:

python manage.py rebuild_index or python manage.py rebuild_index -v2

I get:

Indexing 0 titles
Indexing 0 articles
Indexing 0 People

I've also run python manage.py rebuild_article_search_data and nothing is shown on screen.

I've installed aldryn-newsblog(version=1.3.1), aldryn-search(version-0.3.0) and django-haystack(version=2.6.0).

These are my configurations:

`HAYSTACK_SIGNAL_PROCESSOR = 'haystack.signals.RealtimeSignalProcessor'
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.elasticsearch2_backend.Elasticsearch2SearchEngine',
'URL': 'http://127.0.0.1:9200/',
'INDEX_NAME': 'haystack',
},
}

HAYSTACK_ROUTERS = ['aldryn_search.router.LanguageRouter',]
ALDRYN_SEARCH_LANGUAGE_FROM_ALIAS = lambda alias: alias.split('-')[-1]
ALDRYN_NEWSBLOG_SEARCH = True`

Any help would be appreciated.
