芹菜和兔子MQ姜戈

Question

我用以下命令安装了Celery和RabbitMQ：pip install celery和sudo apt-get install rabbitmq. 芹菜不起作用;我收到此错误：

Traceback (most recent call last):
File "/home/morilon/dj/shop/lib/python3.5/site-
packages/celery/app/utils.py", line 361, in find_app
found = sym.app
AttributeError: module 'myshop' has no attribute 'app'

在处理上述异常期间，发生了另一个异常：

Traceback (most recent call last):
File "/home/morilon/dj/shop/bin/celery", line 11, in <module>
sys.exit(main())
File "/home/morilon/dj/shop/lib/python3.5/site-packages/celery/__main__.py", line 14, in main
_main()

self.app = self.find_app(app)

return find_app(app, symbol_by_name=self.symbol_by_name)
File "/home/morilon/dj/shop/lib/python3.5/site-packages/celery/app/utils.py", line 366, in find_app
found = sym.celery
AttributeError: module 'myshop' has no attribute 'celery'

我不明白该怎么办？

tasks.py

from celery import task
from django.core.mail import send_mail
from .models import Order
@task
def order_created(order_id):
"""
Task to send an e-mail notification when an order is successfully created.
"""
order = Order.objects.get(id=order_id)
subject = 'Order nr. {}'.format(order.id)
message = 'Dear {},nnYou have successfully placed an order. Your order id is {}.'.format(order.first_name,
       order.id)
mail_sent = send_mail(subject, message, '[e-mail]', [order.email])
return mail_sent

celery.py

import os
from celery import Celery
from django.conf import settings
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myshop.settings')
app = Celery('myshop')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

初始化.py

从 .celery 导入应用程序作为celery_app

Answer 1

尝试仔细检查settings.py所在的项目目录中文件celery.py的拼写

或者你可以按照这个文档在 Django 中使用芹菜来获得更多解释

Answer 2

导入芹菜应用程序的__init__.py文件在哪里？它是否在shop/myshop/目录中？因此，它需要在myshop应用程序中，以便在启动时加载芹菜应用程序。
