Why can't Celery daemon see tasks?

由 南笙酒味 提交于 2019-12-22 18:25:06
问题 I have a Django 1.62 application running on Debian 7.8 with Nginx 1.2.1 as my proxy server and Gunicorn 19.1.1 as my application server. I've installed Celery 3.1.7 and RabbitMQ 2.8.4 to handle asynchronous tasks. I'm able to start a Celery worker as a daemon but whenever I try to run the test "add" task as shown in the Celery docs, I get the following error: Received unregistred task of type u'apps.photos.tasks.add'. The message has been ignored and discarded. Traceback (most recent call

I will be nice if I can still use django celery admin pages and read results stored in this different database :) 回答1: It should be possible to set up a separate database for the django-celery models using Django database routers: https://docs.djangoproject.com/en/1.4/topics/db/multi-db/#automatic-database

Run Unittest On Main Django Database

由 不羁岁月 提交于 2019-12-22 10:56:53
问题 I'm looking for a way to run a full celery setup during django tests, asked in this other SO question After thinking about it, I think I could settle for running a unittest (it's more of an integration test) in which I run the test script against the main Django (development) database.
