kombu

问题 It seems as though messages are not getting put onto the queue properly. I'm using Django with Celery and Kombu to make use of Django's own database as a Broker Backend. All I need is a very simple Pub/Sub setup. It will eventually deploy to Heroku, so I'm using foreman to run locally. Here is the relevant code and info: pip freeze Django==1.4.2 celery==3.0.15 django-celery==3.0.11 kombu==2.5.6 Procfile web: source bin/activate; python manage.py run_gunicorn -b 0.0.0.0:$PORT -w 4; python

问题 I want to use messaging library in my application to interact with rabbitmq. Can anyone please explain the differences between pika and kombu library? 回答1: Kombu and pika are two different python libraries that are fundamentally serving the same purpose: publishing and consuming messages to/from a message broker. Kombu has a higher level of abstraction than pika. Pika only supports AMQP 0.9.1 protocol while Kombu can support other transports (such as Redis). More generally, Kombu is more

问题 I am running an application with django, and I wanted to use celery to make some scheduled tasks. According to the oficial docs, in my settings.py file I set the broker transport BROKER_URL = 'django://' and added kombu.transport.django to installed apps INSTALLED_APPS = ( .... 'kombu.transport.django', ....) However, when I try to sync the database, with python manage.py syncdb , i get the following error: Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from

问题 I'm using Django and Celery and I'm trying to setup routing to multiple queues. When I specify a task's routing_key and exchange (either in the task decorator or using apply_async() ), the task isn't added to the broker (which is Kombu connecting to my MySQL database). If I specify the queue name in the task decorator (which will mean the routing key is ignored), the task works fine. It appears to be a problem with the routing/exchange setup. Any idea what the problem could be? Here's the

问题 I have a REST API written in Django, with and endpoint that queues a celery task when posting to it. The response contains the task id which I'd like to use to test that the task is created and get the result. So, I'd like to do something like: def test_async_job(): response = self.client.post("/api/jobs/", some_test_data, format="json") task_id = response.data['task_id'] result = my_task.AsyncResult(task_id).get() self.assertEquals(result, ...) I obviously don't want to have to run a celery

问题 I have a simple application that sends & receives messages, kombu, and uses Celery to task the message. Kombu alon, I can receive the message properly. when I send "Hello", kombu receives "Hello". But when I added the task, what kombu receives is the task ID of the celery. My purpose for this project is so that I can schedule when to send and receive messages, hence Celery. What I would like to know is why is kombu receiving the task id instead of the sent message? I have searched and
