如何设置默认芹菜队列？

Question

我在Django中的芹菜设置：

CELERY_BROKER_URL = 'redis://localhost:6379'
CELERY_RESULT_BACKEND = 'redis://localhost:6379'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TASK_SERIALIZER = 'json'
CELERY_QUEUES = (
    Queue('high', routing_key='high'),
    Queue('normal', routing_key='normal'),
)
CELERY_DEFAULT_QUEUE = 'normal'

如果我在任务中设置队列名称，则可以使用。但是，如果我不这样做，则默认队列设置将不起作用。

# It's ok
@periodic_task(run_every=timedelta(minutes=10), name='Delete props', queue='normal')
def delete_props():
    delete_props()

# It doesn't work
@periodic_task(run_every=timedelta(minutes=10), name='Delete props')
def delete_props():
    delete_props()

如何设置默认队列并且不在任务参数中设置？
