Django-Haystack elasticsearch error in index_queryset - elasticsearch

Question

when trying to build indexes for elasticsearch on django-haystack, i get the error (full traceback below)
TypeError: index_queryset() got an unexpected keyword argument 'using'
It is on Python 2.6, Django 1.4, ElasticSearch 0.20.2. Previously i have encountered a similar prefetch error, which was the case of version mismatch between pyelasticsearch and requests library. i've tried to downgrade requests to 0.13, but no effect. pyelasticsearch is currently 0.3
any help very much appreciated!

The problem is in the version of django-haystack. The current version is 0.3, while few months ago it was 1.0, which is a bit of misunderstanding.
My way to solve the problem is simple and straightforward - install the latest version (0.3), then get the older version (in this case - 1.0) and simply overwrite haystack sources.
the conclusion: "older 1.0" works smooth with the latest versions of all prerequisites (pyelasticsearch, simplejson and requests), while "newer 0.3" doesn't
