[Django]-Updating a Haystack search index with Django + Celery

30👍

the easiest way to do this would probably be to run the management command directly from python and run it in your task

from haystack.management.commands import update_index
update_index.Command().handle()

As for version 2.0.0 beta of haystack, this code should work:

from haystack.management.commands import update_index
update_index.Command().handle(using='default')

I find this package to be a great, easy plug-in app to provide haystack indexing via celery. I used it in a few projects.

Also, since version 2 of the haystack you can call rebuild index from python as

from haystack.management.commands import update_index, rebuild_index
rebuild_index.Command().handle(interactive=False)

Where the “interactive” would prevent haystack asking question if you really want to rebuild index. This is equivalent to –no-input command line option.

If you use xapian as FTS backend please remember that multithreaded updates to index would result in DB Write Lock. So, the solution with celery-haystack package does attempt to spread index update into multiple workers (multiple thread) resulting in the lock with xapian.
