因此,我们有一个包含多个应用程序的Django项目,并且我们将celery用于任务。我们遇到的问题是只有一个应用程序的task.py内部的任务将运行,其他应用程序中的其他task.py任务将返回以下错误:
declare(strict_types=1);
当我运行test_task.delay()时会发生这种情况
这是供应商的task.py:
celery_1 | [2018-10-22 08:27:59,563: ERROR/MainProcess] Received unregistered task of type 'biko.supplier.tasks.test_task'.
celery_1 | The message has been ignored and discarded.
celery_1 |
celery_1 | Did you remember to import the module containing this task?
celery_1 | Or maybe you're using relative imports?

celery_1 | Please see
celery_1 | http://docs.celeryq.org/en/latest/internals/protocol.html
celery_1 | for more information.
celery_1 |
celery_1 | The full contents of the message body was:
celery_1 | b'[[], {}, {"callbacks": null, "errbacks": null, "chain": null, "chord": null}]' (77b)
celery_1 | Traceback (most recent call last):
celery_1 | File "/usr/local/lib/python3.6/site-packages/celery/worker/consumer/consumer.py", line 557, in on_task_received
celery_1 | strategy = strategies[type_]
celery_1 | KeyError: 'biko.supplier.tasks.test_task'
这是商店task.py的一部分,任务可以正常运行:
from config.celery import app
@app.task(shared=True)
def test_task():
print("Runnign this task correctly")
这是芹菜配置:
from django.contrib.contenttypes.models import ContentType
from config.celery import app
from celery_once import QueueOnce
from django.core.management import call_command
from django.utils import timezone
from raven.contrib.django.raven_compat.models import client
from biko.shop.models import Shop
from config.settings import MAX_INCOMING_BUFFER_RETRIES
from biko.buffer.models import IncomingBuffer, OutgoingBuffer
@app.task(shared=True)
def buffer_products(shop_id):
shop = Shop.objects.get(id=shop_id)
shop.get_manager().buffer_products()
任何不属于shop / tasks.py的任务都不会显示为正在加载。我不知道为什么它会从shop / tasks.py而不是从另一个应用程序加载任务。
答案 0 :(得分:2)
在Celery配置中;您可以执行以下操作:
# Where app_module represents where tasks exists.
app = Celery('biko', include=['app_module.tasks'])
# Your line should also work, but sometimes it needs the apps configs
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
