芹菜周期性任务不是

Question

我在django项目中使用芹菜来运行定期任务。遵循celery网站的标准教程，下面是我的项目结构 项目

|_ settings.py
|_ __init__.py
|_ celery_app.py (instead of celery.py)
|_ app
   |_ tasks.py

相关零件设置.py看起来像这样-

^{pr2}$

芹菜_应用程序副本看起来像这样-

from __future__ import absolute_import
import os
from celery import Celery
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
app = Celery('project')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

在任务.py看起来像这样-

from __future__ import absolute_import
from celery.utils.log import get_task_logger
from celery import task
from celery_app import app

logger = get_task_logger(__name__)

@app.task
def test_task():
    for i in range(0, 4):
        logger.debug("celery test task")

当我管理芹菜工人，我可以看到我的任务被发现-

$ python manage.py celery -A project worker --loglevel=DEBUG --app=celery_app:app

当我运行beat时，它显示正在从中获取任务设置.py，但它从未真正运行过。在

$ python manage.py celery -A project beat --app=celery_app:app --loglevel=DEBUG

[2016-04-24 23:55:04,059: DEBUG/MainProcess] Current schedule:
<ModelEntry: test_task tasks.test_task(*[], **{}) {4}>

我错过了什么？在

Answer 1

尝试设置CELERY_ALWAYS_EAGER = False。在

设置CELERY_ALWAYS_EAGER = True使任务同步运行，而不使用celery。通过将其切换为False，将使芹菜跳动起来，并定期运行它。当您不希望celery处理任务时，将在开发模式中使用False开关。在
