在Flask-Celery中收到類型為“”的未注冊任務

Question

我正在嘗試將celery集成到我的應用程序中，但出現此錯誤，提示Received unregistered task of type "". The message has been ignored and discarded. Received unregistered task of type "". The message has been ignored and discarded. 我的Celery應用實例的創建過程如下：

from celery import Celery


def make_celery(app):
    celery = Celery(app.import_name, broker=app.config['CELERY_BROKER_URL'])
    celery.conf.update(app.config)
    TaskBase = celery.Task

    class ContextTask(TaskBase):
        abstract = True

        def __call__(self, *args, **kwargs):
            with app.app_context():
                return TaskBase.__call__(self, *args, **kwargs)
    celery.Task = ContextTask
    return celery

我的任務文件如下所示：

from flask import current_app
from .. import celery

from ..models.models import MobileRedemption


@celery.task(name='process_new_redemption')
def task_process_new_redemption(red_id):
    redemption = MobileRedemption.objects(id=red_id).first()

    if redemption:
        assert isinstance(redemption, MobileRedemption)
    print ("Redemption Successful.....!")


@celery.task(name='process_delete_redemption')
def task_delete_redemption(red_id):
    current_app.logger.info("reached here!")
    redemption = MobileRedemption.objects(id=red_id).first()
    print(redemption)
    redemption.delete()

我究竟做錯了什么？

在Celery構造中，應include任務文件：

celery = Celery(app.import_name, 
                broker=app.config['CELERY_BROKER_URL'],
                include=['path.to.tasks'])
