I’ve got this config for celery app:

from __future__ import absolute_import, unicode_literals
from datetime import timedelta
from celery import Celery
from celery.schedules import crontab
from django.conf import settings

settings.configure()
app = Celery('core', include=['core.tasks'])
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

app.conf.beat_schedule = {
    'add-every-30-seconds': {
        'task': 'core.tasks.send_not_connected',
        'schedule': timedelta(seconds=30),
    },
}

And I run this command to start celery

celery -A core --config=settings.dev worker -l info

I want to pass parameter from settings to task

import pika
from celery import shared_task
from core.celery import app
from django.conf import settings

@shared_task()
def send_message_to_discord(message):

    url = settings.RABBITMQ_URL
    connection = pika.BlockingConnection(pika.URLParameters(url))

    channel = connection.channel()
    channel.queue_declare(queue='discord_message_to_channel')
    channel.basic_publish(exchange='', routing_key='discord_message_to_channel', body=message)
    connection.close()

And I’ve got an error

AttributeError: module 'django.conf.global_settings' has no attribute 'RABBITMQ_URL'

I tried different approaches and didn’t find any working solution. I need this config because I have different setup for DEV and PROD, have separate files in settings directory.
