Django-celery 不工作

Question

celery.py :-

from future import absolute_import

import os
import django

from celery import Celery
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'demo.settings')
django.setup()

app = Celery('demo')

app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

tasks.py:-

from demo.celery import app

@app.task
def hello_world():
    print('Hello World')

views.py:-

from django.shortcuts import render
from django.views.generic import TemplateView

from .tasks import hello_world

class IndexView(TemplateView):
    template_name = 'home/index.html'

    def get_context_data(self, kwargs):
        context = super(IndexView, self).get_context_data(kwargs)
        hello_world.delay()
        return context

我不知道我这个简单的代码有什么问题。这是行不通的，它让我真的与众不同。我从4天开始工作。我是 python、django 和 celery 的新手。有没有人会在这方面帮助我？请给我完整的指导，因为我是 python 新手。

Answer 1

在您的 views.py 中，您尝试从名为 .tasks 的模块导入

from .tasks import hello_world

根据您的堆栈跟踪，这不存在

Exception Value: No module named tasks

您确定在您的导入结构的那个级别中有一个名为 tasks 的模块吗？
