Question

我使用命令安装了Celery和RabbitMQ： def classify_image(request): if request.method == 'POST' and request.FILES['test_image']: test_image = request.FILES['test_image'] test_image = cv2.imread(test_image) test_image = cv2.resize(test_image, (128, 128)) test_image = np.array(test_image) test_image = test_image.astype('float32') test_image /= 255 print(test_image.shape) test_image = np.expand_dims(test_image, axis=0) pred = model.predict_classes(test_image) print(pred) return JsonResponse(pred, safe=False)和pip install celery。芹菜不起作用;我收到这个错误：

sudo apt-get install rabbitmq

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/lib/python3.5/site-
packages/celery/app/utils.py", line 361, in find_app
    found = sym.app
AttributeError: module 'myshop' has no attribute 'app'

我不明白该怎么办？

tasks.py

Traceback (most recent call last):

    sys.exit(main())

celery.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 {},\n\nYou have successfully placed an order. Your order id is {}.'.format(order.first_name,
                                                                             order.id)
    mail_sent = send_mail(subject, message, 'admin@myshop.com', [order.email])
    return mail_sent

初始化的.py

<。>从.celery导入应用程序as celery_app

GitHub上的这个项目https://github.com/Loctarogar/Django-by-Example

Answer 1

导入芹菜应用的__init__.py文件在哪里？它在shop/myshop/目录中吗？所以它需要在myshop应用程序内部才能在启动时加载芹菜应用程序。

Answer 2

尝试在celery.py所在的项目目录中仔细检查文件settings.py的拼写
