celery-haystack-ng 2.0

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.

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.

Usage

1. Add 'celery_haystack' to the INSTALLED_APPS setting

   INSTALLED_APPS = [
       # ..
       'celery_haystack',
   ]

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

   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

   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.
