Django Haystack ElasticSearch Python3 - django

Question

my plan is to get Django with an ElasticSearch backend running using Python3 on a Debian 7.5-64bit machine.
I'll explain every single step, cause i'm nor a professional admin, neither a ready developer.
Not to forget, i'm dealing with this problem the third evening and i feels like i have tried every single tip in the internet.
First, I unpacked, configured, made, made test, made install Python-3.4.1 in my /usr/local/. This created links/bins in usr/local/bin. So i created symlinks from /usr/bin to /usr/local/bin and "installed" different python3 (3.2 from within debian, and 3.4) with update-alternatives. I created alternatives for python3 and python3-config.
The same with Java 8u11 Server-JRE.
I went on installing Django 1.6.5, Haystack 2.1, pyelasticsearch 0.6.1 with at least EVERY pip installed in /usr/bin and /usr/local/bin (pip has also installed requests 2.3.0, simplejson 3.6.0, six 1.7.3).
Meanwhile i also installed pyes 0.99.2 and urllib3 1.9. Both with pip.
Django is configured and running, also apache with mod-wsgi modul. I created a django project and an app (no models yet).
Elasticsearch is also running, but without any indizes yet.
To my project/settings.py i edited and added:
INSTALLED_APPS = {...
'haystack'}
...
DATABASES = {
'default': {
'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
'URL': 'http://127.0.0.1:9200/',
'NAME': 'haystack',
}
...
}
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
'URL': 'http://127.0.0.1:9200/',
'INDEX_NAME': 'haystack',
},
}
When i run ./manage.py from within projectfolder I get following error:
./manage.py syncdb

And like the shebang in manage.py says, this so uses python2.7.
Then forcing my python 3.4 interpeter:
python3 ./manage.py syncdb

A ls shows, that the file is there, and with an editor i see, that the class exists
/usr/local/lib/python3.4/site-packages/haystack/backends/elasticsearch_backend.py
Did I forget ANYTHING? Should there be anything in "PYTHONPATH" which is under python-lib directory? Which information could also be important?
At least: Is this setup even possible? Did i understand the structure of django-haystack and database-backend correct?
Please help me. I'm tired of and done with the docu and samples from django, haystack, elasticsearch and the most targeting google hits.

Answer 1

syncdb command will try to sync your models with the database. Django is not able to interpret ElasticsearchSearchEngine as a database. You should use correct ENGINE value corresponding to the database you are using.
e.g. For MySQL
ENGINE='django.db.backends.mysql'
Do you intend to use database at all? If not then do not run syncdb.

Answer 2

Your database setting is wrong. You should use any of the database engine here like :
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': 'mydatabase',
}
}
if you choose to use sqlite database in your project.
