在Flask-Celery中收到类型为“”的未注册任务

Question

I'm trying to integrate celery into my app but I am getting this error saying Received unregistered task of type "". The message has been ignored and discarded. Received unregistered task of type "". The message has been ignored and discarded. My Celery app instance is being created like so:

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

My tasks file is like so:

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()

What am I doing wrong?

In your Celery construction you should include your tasks files:

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