Django Celery Task: AttributeError: type object 'Command' has no attribute 'annotations'

Question

我正在尝试设置一个 celery 任务，它基本上是运行一个脚本，用于停用 json 文件中的一系列设施。我曾经手动运行它并且它运行很好但是现在当 Celery 尝试运行它作为一项任务时我收到以下错误：

AttributeError: type object 'Command' has no attribute '__annotations__'

谁能告诉我为什么它不起作用？这是我正在使用的代码：

tasks.py

import requests
import json

from project.users.models import Facility
from django.core.management.base import BaseCommand
from config import celery_app

IMPORT_URL = 'https://example.com/file.json'

@celery_app.task()
class Command(BaseCommand):
    def delete_facility(self, data):
                    
                    data = data
                    

                    if Facility.objects.filter(UUID=data, ReportedStatusField='closed'):
                        
                        print("Facility status already set to closed")


                    else:
                        
                        facility, facility_closed = Facility.objects.update_or_create(UUID=data,
                            defaults={
                            'ReportedStatusField': 'closed'
                            }
                        )
                        print("Facility status set to closed")
                        

    def handle(self, *args, **options):

        headers = {'Content-Type': 'application/json'}
        response = requests.get(
            url=IMPORT_URL,
            headers=headers,
        )

        response.raise_for_status()
        data = response.json()


        for data, data_object in data.items():
            if data in ["deleted"]:
                for data in data_object:
                    self.delete_facility(data)

我想我明白了。现在是运行。我从 tasks.py 调用基本命令文件，而不是将代码直接添加到 tasks.py:

from celery import shared_task
from django.core.management import call_command

@shared_task
def start_import():
    call_command("import_from_url", )

Django Celery Task: AttributeError: type object 'Command' has no attribute '__annotations__'

Django Celery Task: AttributeError: type object 'Command' has no attribute '__annotations__'

python

django

celery
