如何从另一个模块接收芹菜任务

Question

I can successfully receive celery tasks from my main app - however, my system cannot receive tasks from another module. I'm on a remote Ubuntu server using supervisor for for celery.

draft1 is my main app and post is another module (the one that I can't receive tasks from).

draft1/__init__.py

#This will make sure the app is always imported when
#Django starts so that shared_task will use this app.
from .celery import app as celery_app

__all__ = ['celery_app']

draft1/celery.py

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'draft1.settings')

app = Celery("draft1", broker=CELERY_BROKER_URL, include=['post'])
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS) #post is in my installed apps

draft1/tasks.py

@periodic_task(run_every=timedelta(minutes=1))
def test_job():
    from polls.models import Question
    for i in Question.objects.all():
        if i.question_text == "test":
            i.question_text = "not_test"
            i.save()
    return HttpResponseRedirect('/')


@periodic_task(name='run_scheduled_jobs', run_every=timedelta(seconds=30))
def run_scheduled_jobs():
    return True

post/tasks.py

@periodic_task(name='test_post', run_every=timedelta(seconds=30))
def test_post():
    from .models import Post
    for i in Post.objects.all():
        if i.entered_category == "test":
            i.entered_category = "not_test"
            i.save()
    return HttpResponseRedirect('/')


@periodic_task(name='post_jobs', run_every=timedelta(seconds=30)) # task name found! celery will do its job
def post_jobs():
    # do whatever stuff you do
    return True

settings.py

CELERYBEAT_SCHEDULE = {
    'run_scheduled_jobs': {
        'task': 'run_scheduled_jobs', # the same goes in the task name
        'schedule': timedelta(seconds=45),
    },
    'test_job': {
            'task': 'tasks.test_job',
            'schedule': timedelta(minutes=3),
    },
    'post_jobs': {
        'task': 'post.tasks.post_jobs',  #i've also tried tasks.post_jobs
        'schedule': timedelta(minutes=1),
    },
    'test_post': {
        'task': 'post.tasks.test_post',
        'schedule': timedelta(seconds=45),
    }
}

Here is my command to start the worker: celery -A draft1 worker -l info

and celery beat is started via: celery -A draft1 beat -l info --scheduler .

The tasks from draft1/tasks.py are the only tasks I receive:

Why is this?

Answer 1

The celery -A switch you are passing explicitly creates a worker for only the draft1 app. You'll want a separate worker for the post app, as well as setting up a celery.py for that one to, so that you can create a separate Celery instance for the post tasks. These can obviously share the same message broker if you want (and you probably do).
