importing current_app from celery is gives ValueError: attempted relative import beyond top-level package

Question

Yes I know there are lot's of similar questions on stack-overflow related to this value-error and I tried all the solutions from them but as I am new to Django and python I am not able to solve this issue.

I have one project called my_backend which have the following file structure.

main_project/
   cmb_backend/
        __init__.py
        celery.py
        urls.py
    second_app/
        __init__.py
        moduleZ.py
    my_env/
       bin/
       include/
       lib/
         python 3.7/
           site-packages/
             celery/
             django_celery_beat
               admin.py

I have used celery for the periodic task so I have added one celery.py file in my main application my_backend.

I have also installed django_celery_beat using pip and inside that, they have imported celery using below code.

# admin.py file in the django_celery_beat lib
from celery import current_app
from celery.utils import cached_property

so when I run this command

python3 my_backend/setup_database.py

it is giving me an error like

ImportError: cannot import name 'current_app' from 'celery' (/Users/pankaj/Desktop/Pankaj/MyJangoProjects/My_Project/my_backend/celery.py)

so from this error, I found that when I am running above command admin.py is importing current_app from celery but it is looking in the wrong file

so to solve this error I am using relative import and adding .. in front of import statement but still, it's not working

# admin.py file in the django_celery_beat lib
from ..celery import current_app
from ..celery.utils import cached_property

Now here I am getting ValueError: attempted relative import beyond top-level package

I have tried some sys.path hack but my bad, I am still stuck here.

I have also checked all these questions and tried solutions which are provided there.

Answer 1

Your error is probably related to the celery.current_app is somewhat not included in your PYTHONPATH . Make sure these two items are satisfied:

1. Make sure celery.current_app package is installed somewhere under your PYTHONPATH .
2. If you are using virtual environment, make sure celery is installed and your virtual environment is activated.

Answer 2

I found the solution to this problem. As I mentioned the issue was the same name of the file in my main app, as the file name was celery.py when I run django_celery_beat it was looking for current_app inside my custom celery.py file so I have changed the file name to my_task.py as the @cagrias suggested.

I have appended app name in the below command and it's working now.

celery -A my_backend.task worker --loglevel=info
