Próbuję uruchomić serwer pracownika Celery z linii poleceń:

celery -A tasks worker --loglevel=info

Kod w task.py:

import os
os.environ[ 'DJANGO_SETTINGS_MODULE' ] = "proj.settings"

from celery import task

@task()
def add_photos_task( lad_id ):
...

Dostaję następny błąd:

Traceback (most recent call last):

Czy ktoś wie, dlaczego nie można znaleźć atrybutu „selera”? Dziękuje Ci za pomoc.

System operacyjny to Linux Debian 5.

Edytować. Może być wskazówką. Czy ktoś mógłby mi wyjaśnić następny komentarz do funkcji (dlaczego musimy być pewni, że znajdzie moduły w bieżącym katalogu)?

# from celery/utils/imports.py
def import_from_cwd(module, imp=None, package=None):
    """Import module, but make sure it finds modules
    located in the current directory.

    Modules located in the current directory has
    precedence over modules located in `sys.path`.
    """
    if imp is None:
        imp = importlib.import_module
    with cwd_in_path():
        return imp(module, package=package)
