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 :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:

.. 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
