[Django]-Can't get Elasticsearch working with Django

Seems you’ve already fixed it, but for future Googlers: some people have trouble with the Haystack versions on pip around 2014-2015. Fixing the version at 2.1.0 seems to fix it, as does downloading 2.4.0 directly from git:

pip install git+https://github.com/django-haystack/django-haystack

UPDATE: The current version of haystack in pypi works (nov 2015), be sure to update!
