Eve-Elastic 0.5

Elasticsearch data layer for eve rest framework

Eve-Elastic is elasticsearch data layer for eve REST framework.

Features

• fulltext search

• elasticsearch mapping generator for schema

License

Eve-Elastic is GPLv3 licensed.

Install

$ pip install Eve-Elastic

Usage

Set elastic as your eve data layer.

import eve
from eve_elastic import Elastic

app = eve.Eve(data=Elastic)
app.run()

Config

There are 2 options for Eve-Elastic taken from app.config:

• ELASTICSEARCH_URL (default: 'http://localhost:9200/') - this can be either single url or list of urls

• ELASTICSEARCH_INDEX - (default: 'eve')

• ELASTICSEARCH_INDEXES - (default: {}) - resource to index mapping

• ELASTICSEARCH_FORCE_REFRESH - (default: True) - force index refresh after every modification

• ELASTICSEARCH_AUTO_AGGREGATIONS - (default: True) - return aggregates on every search if configured for resource

Query params

Eve-Elastic supports eve like queries via where param which work as term filter.

On top of this, there is a predefined query_string query which does fulltext search.

$ curl http://localhost:5000/items?q=foo&df=name

• q - query (default: *)

• df - default field (default: _all)

Filtering

For more sophisticated filtering, you can use filter query param which will be used as filter for the query, using elastic filter dsl.

Facets

To add a facets support for specific resource, add facets into its datasource:

DOMAIN = {
    'contacts': {
        'datasource':
            'facets': {
                'urgency': {'terms': {'field': 'urgency'}},
                'versioncreated': {'date_histogram': {'field': 'versioncreated', 'interval': 'hour'}}
            }
        }
    }

You will find more info about facets in elasticsearch docs.
