模块“module”没有属性“celery”

[英]Module 'module' has no attribute 'celery'

我需要在我的项目中使用 Celery,但是当我尝试在我的项目中安装时遇到了一些错误。 我已经阅读了DjangoCelery 文档,但我一直在犯同样的错误。

我的树项目:

  • 📂 src
    • 📄 __init__.py

    • 📄芹菜.py

    • 📂核心

      • 📄 __init__.py
    • 📂 project_auth

      • 📄 __init__.py
      • 📄serializer.py
      • 📄任务.py
    • 📄 设置.py

    • 📄 urls.py

    • 📄wsgi.py

  • 📄 texto.md

src/_初始化_.py :

# 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',)

源代码/芹菜.py:

import os

from celery import Celery
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'src.settings')
app = Celery('src')
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

@app.task(bind=True)
def debug_task(self):
    print(f'Request: {self.request!r}')

src/settings.py :


INSTALLED_APPS = [
    #Django apps :
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    #Meus apps : 
    'src.core',
    'src.project_auth',
    'src.product',
    #Apps de terceiros :   
    'django_celery_results',
    'rest_framework',
    "rest_framework.authtoken",    
]

CELERY_CONFIG = {
    "CELERY_TASK_SERIALIZER": "json",
    "CELERY_ACCEPT_CONTENT": ["json"],
    "CELERY_RESULT_SERIALIZER": "json",
    "CELERY_RESULT_BACKEND": None,
    "CELERY_TIMEZONE": "UTC",
    "CELERY_ENABLE_UTC": True,
    "CELERY_ENABLE_REMOTE_CONTROL": False,
}

docker-compose.yml:

celery --app src.project_auth bash 上,我运行celery --app src.project_auth并得到:

Error: Invalid value for '-A' / '--app': 
Unable to load celery application.
Module 'src.project_auth' has no attribute 'celery'

谢谢你的帮助 !

看起来您的celery.py文件位于错误的位置,从错误消息中您应该将celery.py移动到project_auth文件夹中。

Module 'src.project_auth' has no attribute 'celery'

这表明 Celery 期待src/project_auth/celery.py而你有src/celery.py

另一种选择是将 bash 脚本更改为

celery --app src

祝你好运!
