芹菜"收到未注册的任务"

Question

我是芹菜的新手,并试图在我的应用程序中使用它.以下是我的基本应用程序结构

 my_app
 |-run.py
 |-app
    |-mod1
    |-mod2
    |-tasks
       |-__init__.py
       |-email
       |-other_tasks_file

我想将所有后台任务限制在我的任务模块中.在我的任务的init .py中

from celery import Celery

celery = Celery('my_app', broker='redis://localhost:6379/0')

在我的任务/电子邮件中我有

from app.tasks import celery

@celery.task
def send_email():
    #do stuff

从终端我开始使用工人

 celery -A app.tasks worker --loglevel=DEBUG

但我的任务没有出现在芹菜的任务列表中.此外,一旦我从解释器运行我的任务就像这样

>>from app.tasks import email
>>email_result = email.send_email.delay()

当我这样做时,我在芹菜终端得到以下回复

Received unregistered task of type 'app.tasks.emails.send_email'.
The message has been ignored and discarded.

Did you remember to import the module containing this task?
Or maybe you are using relative imports?
Please see url for more information.

The full contents of the message body was:
{'kwargs': {}, 'taskset': None, 'id': '51e8f766-e772-4d85-bad0-5a6774ea541a', 'eta': None, 'timelimit': (None, None), 'args': [], 'retries': 0, 'task': 'app.tasks.emails.send_email', 'utc': True, 'errbacks': None, 'chord': None, 'expires': None, 'callbacks': None} (283b)

During handling of the above exception, another exception occurred:

strategies[name](message, body,
KeyError: 'app.tasks.channels.send_email'

我使用的是python 3.4和芹菜3.1.23

如果有人需要它,我终于开始工作了.我需要做的是为一个包含任务的实际文件运行一个芹菜工人,以便芹菜注册任务 -

celery -A app.tasks.emails worker --loglevel=DEBUG  

因为只是跑步

celery -A app.tasks worker --loglevel=DEBUG

(这是我疯狂的猜测)实际上不会导入我的send_email()任务.如果有人能给我一个解释,请做.
