Django Celery，不执行计划任务

如何解决Django Celery，不执行计划任务

我正在开发一个 Django 应用程序来跟踪加密资产，我想要做的是每 5 天（X 次）拍摄一次用户总价值的快照。

我现在做了什么：

core/celery.py

from __future__ import absolute_import,unicode_literals
import os
from celery import Celery
from celery.schedules import crontab

# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE','core.settings')

app = Celery('core')

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.

app.config_from_object('django.conf:settings',namespace='CELERY')


app.conf.beat_schedule = {
    'print': {
        'task': 'app.tasks.test','schedule': 15
    },}
app.conf.timezone = 'UTC'

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()


@app.task(bind=True)
def debug_task(self):
    print('Request: {0!r}'.format(self.request))

core/settings.py:

import os
from decouple import config
from unipath import Path
import dj_database_url
import django


# Build paths inside the project like this: os.path.join(BASE_DIR,...)
BASE_DIR = Path(__file__).parent
CORE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

# Security WARNING: keep the secret key used in production secret!
SECRET_KEY = config('SECRET_KEY',default='S#perS3crEt_1122')

# Security WARNING: don't run with debug turned on in production!
DEBUG = config('DEBUG',default=True,cast=bool)

# load production server from .env
ALLOWED_HOSTS = ['localhost','127.0.0.1','e6b5f240dedb.ngrok.io',config('SERVER',default='127.0.0.1')]

app/tasks.py：

from __future__ import absolute_import,unicode_literals
from celery import shared_task


@shared_task
def test():
    print("Message for me and for you")

之后，当我执行

celery -A core worker -l info

我收到错误“芹菜：找不到命令”

注意：我执行了 python manage.py migrate，并且我能够在管理页面中看到新表。 当我运行项目时，没有显示错误，但任务没有执行。

谢谢！

解决方法

您的服务器上似乎还没有安装 Django Celery，请运行

pip install django-celery

然后重新启动一切
