Extending Haystack's Elasticsearch backend

Haystack provides an interface similar to Django's QuerySet, which instead enables easy querying in one or more popular search backends. Because the Haystack SearchQuerySet API is meant to hook up to several search backends, however, not all the functionality of the backends has been implemented in the API. In this article we show how Haystack's Elasticsearch backend can be extended with advanced querying functionality.

As an exemplary use case, we'll focus on implementing Elasticsearch's Nested Query in the SearchQuerySetAPI, to enable e.g. weighted tags on documents. The usage of this extended API will be shown first, after which we'll go through the necessary implementation steps.

Workflows (States) in Django

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.

Common Software Uses

• Publishing (Draft->Approved->Published->Expired->Deleted)

Kibana Readonly

With this tip, kibana can't be modified. So you can share the uri to anyone on the internet. It's a network method to protect kibana from changes of anonymous.

Quick start

1. You need to have a working kibana exposed over http on internet
2. On the same elasticsearch server, install nginx : apt-get install nginx
3. In the directory /etc/nginx/sites-available, create a new file and edit it, for example : vi /etc/nginx/sites-available/kibana-readonly
4. Write the following configuration :
