Integrate Elasticsearch DSL with Django REST framework.

django-elasticsearch-dsl-drf

Integrate Elasticsearch DSL with Django REST framework in the shortest way possible, with least efforts possible.

Package provides views, serializers, filter backends, pagination and other handy add-ons.

You are expected to use django-elasticsearch-dsl for defining your Elasticsearch documents.

Prerequisites

• Django 1.8, 1.9, 1.10, 1.11, 2.0 and 2.1.
• Python 2.7, 3.4, 3.5, 3.6, 3.7
• Elasticsearch 2.x, 5.x, 6.x

Dependencies

elasticsearch and elasticsearch-dsl

Depending on your Elasticsearch version (either 2.x, 5.x or 6.x) you should use 2.x, 5.x or 6.x versions of the elasticsearch and elasticsearch-dsl packages accordingly.

django-elasticsearch-dsl

You are advised to use the latest version of django-elasticsearch-dsl.

djangorestframework

Perhaps the easiest way to get acquainted with django-elasticsearch-dsl-drf is to read the :doc:`quick start tutorial <quick_start>`.

See it as a guide of diving into integration of Elasticsearch with Django with very low knowledge entry level.

Testing

Project is covered with tests.

To test with all supported Python/Django versions type:

tox

To test against specific environment, type:

tox -e py37-django21

To test just your working environment type:

./runtests.py

To run a single test in your working environment type:

./runtests.py src/django_elasticsearch_dsl_drf/tests/test_filtering.py

Or:

./manage.py test django_elasticsearch_dsl_drf.tests.test_ordering

To run a single test class in a given test module in your working environment type:

./runtests.py src/django_elasticsearch_dsl_drf/tests/test_suggesters.py::TestSuggesters

It's assumed that you have all the requirements installed. If not, first install the test requirements:

pip install -r examples/requirements/test.txt
