thomlinton / celery-haystack

An app for integrating Celery with Haystack.

celery-haystack

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

Requirements

• Django 1.2+
• Haystack 1.2.X or 2.X
• Celery 2.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

By default a few dependencies will automatically be installed:

• django-appconf -- An app to gracefully handle application settings.
• django-celery-transactions -- An app that "holds on to Celery tasks until the current database transaction is committed, avoiding potential race conditions as described in Celery's user guide."

Setup

1. Add 'celery_haystack' to INSTALLED_APPS.
2. Alter all of your SearchIndex subclasses to inherit from celery_haystack.indexes.CelerySearchIndex (as well as haystack.indexes.Indexable if you use Haystack 2.X).
3. 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.
