Celery

Create celery app

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'graduatework_drf.settings')

app = Celery('graduatework_drf')
app.config_from_object("django.conf:settings", namespace="CELERY")
app.autodiscover_tasks()

After that we must add the following code to the init file.

from .celery import app as celery_app

__all__ = ('celery_app',)
