属性错误：模块"模块"没有属性"芹菜"

Question

我想在我的 Django 应用程序中使用芹菜来完成应该在后台运行的任务。我遵循了这些教程 使用 Django 和 Celery 的异步任务 和 Django 的第一步 使用 Celery 与 Django 一起使用

我的项目结构：

project
├──project
|  ├── settings
|     ├──__init__.py   (empty)
|     ├──base.py
|     ├──development.py
|     └──production.py
|  ├──__init__.py
|  └──celery.py
├──app_number_1
|  └──tasks.py

项目/项目/初始化.py ：

from __future__ import absolute_import, unicode_literals
# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app
__all__ = ['celery_app']

项目/项目/芹菜.py ：

from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings.production')
app = Celery('project')
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks()

项目/项目/设置/制作.py ：

INSTALLED_APPS = [
'background_task',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.gis',
]
.
.
.
CELERY_BROKER_URL = 'mongodb://mongo:27017'
CELERY_RESULT_BACKEND = 'mongodb://mongo:27017'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TASK_SERIALIZER = 'json'

docker-compose.yml：

version: '3'
services:
web:
env_file:
- env_vars.env
build: .
restart: always
command:
- /code/runserver.sh
ports:
- "80:8000"
depends_on:
- db
- mongo
db:
...
mongo:
image: mongo:latest
restart: always

runserver.sh：

#!/bin/bash
sleep 1
python3 /code/project/manage.py migrate --settings=project.settings.production
python3 /code/project/manage.py runserver 0.0.0.0:8000 --settings=project.settings.production & celery -A project worker -Q celery

docker-compose up --build后，我收到以下错误：

web_1    | Running migrations:
web_1    |   No migrations to apply.
mongo_1  | 2019-08-28T10:24:26.478+0000 I  NETWORK  [conn2] end connection 172.18.0.4:42252 (1 connection now open)
mongo_1  | 2019-08-28T10:24:26.479+0000 I  NETWORK  [conn1] end connection 172.18.0.4:42250 (0 connections now open)
web_1    | Error: 
web_1    | Unable to load celery application.
web_1    | Module 'project' has no attribute 'celery'

任何提示都会很棒！

谢谢

芹菜模块不包含在第一个项目文件夹中。

您可以将其移动到那里，也可以通过添加 __init__ 模块并将 celery 命令中的应用实例模块设置为：

celery -A project.project worker -Q celery
