celery-haystack-ng

================== celery-haystack-ng

This Django app allows you to utilize Celery for automatically updating and deleting objects in a Haystack_ search index.

Forked from the original celery-haystack_.

Requirements

• Django 2.1+
• Haystack_ 2.X+
• Celery_ 4.X+

You also need to install your choice of one of the supported search engines for Haystack and one of the supported backends for Celery.

.. _Haystack: http://haystacksearch.org .. _celery-haystack: https://github.com/django-haystack/celery-haystack

Installation

Use your favorite Python package manager to install the app from PyPI, e.g.::

pip install celery-haystack-ng

For Django < 1.9 you need to install and configure django-transaction-hooks_ -- an app that brings transaction commit hooks to Django.

.. _django-transaction-hooks: https://github.com/carljm/django-transaction-hooks

Usage

1. Add 'celery_haystack' to the INSTALLED_APPS setting

   .. code:: python

   INSTALLED_APPS = [ # .. 'celery_haystack', ]

2. Enable the celery-haystack signal processor in the settings

   .. code:: python

   HAYSTACK_SIGNAL_PROCESSOR = 'celery_haystack.signals.CelerySignalProcessor'

3. Alter all of your SearchIndex subclasses to inherit from celery_haystack.indexes.CelerySearchIndex and haystack.indexes.Indexable

   .. code:: python

   from haystack import indexes from celery_haystack.indexes import CelerySearchIndex from myapp.models import Note

   class NoteIndex(CelerySearchIndex, indexes.Indexable): text = indexes.CharField(document=True, model_attr='content')

     def get_model(self):
         return Note
   

4. Ensure your Celery instance is running.

Thanks

This app is a blatant rip-off of Daniel Lindsley's queued_search_ app but uses Ask Solem Hoel's Celery_ instead of the equally awesome queues_ library by Matt Croyden.
