为什么芹菜任务不起作用？
为什么芹菜任务不起作用？
提问于 2018-06-02 20:56:44
在我的Django项目中，我需要定期运行celery任务。我用的是芹菜4+ Redis。
首先我运行redis-server，然后使用next命令：
$ celery -A TestProject worker -l info
$ celery -A TestProject beat -l info第一个命令引发下一个错误：

b'[[], {}, {"errbacks": null, "chord": null, "chain": null, "callbacks": null}]' (77b)
Traceback (most recent call last):

from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'TestProject.settings')
app = Celery('TestProject')
# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.

@app.task(bind=True)

最后我找到了解决方案。我编辑celery.py文件：
import os
import sys
from celery import Celery
from celery._state import _set_current_app
import django
from django.conf import settings
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'TestProject.settings')
app = Celery('TestProject')
app.config_from_object('django.conf:settings', namespace='CELERY')
_set_current_app(app)
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '../TestProject')))
django.setup()
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
