我已将djcelery和kombu.transport.django添加到django应用程序中。
import djcelery
djcelery.setup_loader()
from .celery import app as celery_app
BROKER_URL = "redis://abc:abc@localhost:6379/0"
CELERYBEAT_SCHEDULER = "djcelery.schedulers.DatabaseScheduler"
CELERY_TIMEZONE = "Europe/London"
CELERY_ENABLE_UTC = True
# store AsyncResult in redis
CELERY_RESULT_BACKEND = "redis"
REDIS_HOST = "localhost"
REDIS_PORT = 6379
REDIS_DB = 0
REDIS_VHOST = 0
REDIS_USER="xyz"
REDIS_PASSWORD="xyz"
REDIS_CONNECT_RETRY = True
from __future__ import absolute_import
import os
from celery import Celery
from django.conf import settings
from . import celeryconfig
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings')
app = Celery('apps')
# Using a string here means the worker will not have to
# pickle the object when using Windows.
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
@app.task(bind=True)
def debug_task(self):
print('Request: {0!r}'.format(self.request))
[program:celeryd]

当使用django-celery接口安排任务时，该接口应该下载一些文件，抛出以下错误：

SchedulingError: Couldn't apply scheduled task downloader: argument must be an int, or have a fileno() method.
并且我没有得到任何线索来自这些错误......
任何建议都将不胜感激。
我使用django-celery管理界面来安排任务，并在INSTALLED_APP中注册的应用程序中定义任务，如下所示：
@shared_task
def downloader():
# execute static/shell_scripts/feed_downloader.sh
import subprocess
PROJECT_PATH = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
subprocess.call(PROJECT_PATH+"/static/shell_scripts/feed_downloader.sh", shell=True)
feed_downloader.sh文件调用django管理命令，如果我执行独立的工作正常如下：
python manage.py feed_downloader
如果我在行号之前添加一个print语句。 85检查文件中的fd参数
/home/vagrant/.virtualenvs/project/local/lib/python2.7/site-packages/kombu/utils/eventio.py
然后打印以下消息：
see this <socket._socketobject object at 0x131b750>
see this None
see this <socket._socketobject object at 0x131bc90>
see this None
