A Whoosh storage engine using redis for persistance. A Haystack SearchBackend
subclass is also provided. Normally the STORAGE
key could just be set but Haystack 2.0.0beta is only aware of file
and ram
backends.
This is especially useful for small sites hosted on Heroku, which does not allow writing to local disk. The REDISTOGO_URL
environment variable is read, falling back to the localhost default port.
Code is based on maxpert’s snippet (see blog post)
Configure your Haystack connections in settings.py
:
import tempfile
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack_redis.RedisEngine',
'PATH': tempfile.gettempdir(),
},
}
Currently some in-development features are still needed:
$ pip install -e git+https://github.com/andymccurdy/redis-py.git@master@egg=redis
$ pip install -e git+https://github.com/toastdriven/django-haystack.git@master#egg=django-haystack
