我很难让芹菜和django合作。我想使用芹菜刮一个网站,并更新一些django模型每20分钟。
我在我的app目录中创建了一个任务文件,其中包含一个update类:
class Update(PeriodicTask):
run_every=datetime.timedelta(minutes=20)
def run(self, **kwargs):
#update models如果我从命令行运行modesl,该类将正确地更新它:
if __name__ == '__main__':
Update().run()我在setting.py中的芹菜配置如下所示:
CELERY_RESULT_BACKEND = "database"
BROKER_HOST = 'localhost'
BROKER_PORT = 5672
BROKER_USER = 'Broker'
BROKER_PASSWORD = '*password*'
BROKER_VHOST = 'broker_vhost'但是,当我运行manage.py celeryd -v 2时,我会得到连接错误:
[2010-12-29 09:28:15,150: ERROR/MainProcess] CarrotListener: Connection Error: [Errno 111] Connection refused. Trying again in 10 seconds...我遗漏了什么?
更新:
我发现了姜戈-科姆布,它看起来很不错,因为它使用了我现有的数据库。我已经安装了django-kombu和kombu,但是现在我在运行manage.py celeryd -v 2时得到了以下错误。

看起来您没有安装/运行代理(RabbitMQ?)

我也有同样的问题,问题是我错了导入路径。
可能,您将任务导入为
from celery import task。
而你应该
from celery.task import task
