django-elasticsearch-dsl-drf
============================
Integrate `Elasticsearch DSL
<https://pypi.python.org/pypi/elasticsearch-dsl>`_ with
`Django REST framework <https://pypi.python.org/pypi/djangorestframework>`_ 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
<https://pypi.python.org/pypi/django-elasticsearch-dsl>`_ for defining your
Elasticsearch documents.

Demos
=====
Online demo
-----------
Check the `live demo app <https://django-elasticsearch-dsl-drf.herokuapp.com>`__
(Django 3.1 + Django REST Framework 3.12 + Elasticsearch 7.5) hosted on Heroku
and bonsai.io.
Local demo
----------
A frontend demo (React based) is available. See the `dedicated docs
<https://github.com/barseghyanartur/django-elasticsearch-dsl-drf/blob/master/examples/frontend/README.rst>`_
for more information.
To bootstrap evaluation, clone the repository locally and run `docker-compose`.
.. code-block:: sh
docker-compose up
It will set up:
- Elasticsearch on `http://localhost:9200 <http://localhost:9200>`_
- Django REST framework on `http://localhost:8000 <http://localhost:8000>`_
- React on `http://localhost:3000 <http://localhost:3000>`_
Installation
============
(1) Install latest stable version from PyPI:
.. code-block:: sh
pip install django-elasticsearch-dsl-drf
or latest stable version from GitHub:
.. code-block:: sh
pip install https://github.com/barseghyanartur/django-elasticsearch-dsl-drf/archive/stable.tar.gz
(2) Add ``rest_framework``, ``django_elasticsearch_dsl`` and
``django_elasticsearch_dsl_drf`` to ``INSTALLED_APPS``:
.. code-block:: python
INSTALLED_APPS = (
# ...
# REST framework
'rest_framework',
# Django Elasticsearch integration
'django_elasticsearch_dsl',
# Django REST framework Elasticsearch integration (this package)
'django_elasticsearch_dsl_drf',
# ...
)
Quick start
===========
Perhaps the easiest way to get acquainted with ``django-elasticsearch-dsl-drf``
is to read the `quick start tutorial <http://django-elasticsearch-dsl-drf.readthedocs.io/en/0.22.5/quick_start.html>`_.
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:
.. code-block:: sh
tox
To test against specific environment, type:
.. code-block:: sh
tox -e py38-django30
To test just your working environment type:
.. code-block:: sh
./runtests.py
To run a single test in your working environment type:
.. code-block:: sh
./runtests.py src/django_elasticsearch_dsl_drf/tests/test_filtering.py
Or:
.. code-block:: sh
./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:
.. code-block:: sh
./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:
.. code-block:: sh
pip install -r examples/requirements/test.txt
