AttributeError: the 'module' object does not have the 'ElasticSearchError' attribute: using Haystack Elasticsearch

Using Django and Haystack with ElasticSearch.

After installing haystack and ES and rebuild index

./manage.py rebuild_index

A WARNING. This will permanently remove TOTAL from your search index in the default connection. After that, you can restore the backups or rebuild using the rebuild_index . Are you sure you want to continue? [y / N] y

 Removing all documents from your index because you said so. All documents removed. Indexing 1039 <django.utils.functional.__proxy__ object at 0x10ca3ded0>. AttributeError: 'module' object has no attribute 'ElasticSearchError'

Index update has the same problem

 /manage.py update_index Indexing 1039 <django.utils.functional.__proxy__ object at 0x10ea49d90>. AttributeError: 'module' object has no attribute 'ElasticSearchError'

Clear index works fine (maybe because there is no index)

 ./manage.py clear_index WARNING: This will irreparably remove EVERYTHING from your search index in connection 'default'. Your choices after this are to restore from backups or rebuild via the `rebuild_index` command. Are you sure you wish to continue? [y/N] y

Removing all documents from your index because you said that. All documents are deleted.

Versions

pyelasticsearch == 0.5
elasticsearch == 0.20.6

search_indexes.py:

 import datetime import haystack from haystack import indexes from app.models import City class CityIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) name = indexes.CharField(model_attr='name') state = indexes.CharField(model_attr='state') country = indexes.CharField(model_attr='country') lat = indexes.FloatField(model_attr='latitude') lon = indexes.FloatField(model_attr='longitude') alt = indexes.FloatField(model_attr='altitude') pop = indexes.IntegerField(model_attr='population') def get_model(self): return City

Any help - why am I getting an error?

I decided!

After debugging a process using pdb

 ./manage.py rebuild_index

Line 222 - in / haystack / backend / elasticsearch _backend.py

Changed

 except (requests.RequestException, pyelasticsearch.ElasticSearchError), e:

For

 # except (requests.RequestException, pyelasticsearch.ElasticSearchError), e: except Exception as inst: import pdb; pdb.set_trace()

I found that the main mistake was this

 'ElasticSearch' object has no attribute 'from_python'.

Here I found a solution - https://github.com/toastdriven/django-haystack/issues/514#issuecomment-4058230

The version of pyelasticsearch that I used was http://github.com/rhec/pyelasticsearch ,

So, I installed pyelasticsearch from a fork - http://github.com/toastdriven/pyelasticsearch using:

 pip install --upgrade git+https://github.com/toastdriven/ pyelasticsearch.git@3bfe1a90eab6c2dfb0989047212f4bc9fb814803 #egg=pyelasticsearch

and that fixed it, and the index was built!
