django-simple-task runs background tasks in Django 3 without requiring other services and workers. It runs them in the same event loop as your ASGI application. It is not resilient as a proper task runner such as Celery, but works for some simple tasks and has less overall overheads.
django-simple-task expect ASGI lifespan protocol to be supported by the server. Currently Daphne does not support this.
This package is tested with:
Install the package:
pip install django-simple-task
Added it to installed apps:
# settings.py INSTALLED_APPS = [ ... 'django_simple_task' ]
Apply ASGI middleware :
# asgi.py from django_simple_task import django_simple_task_middlware application = django_simple_task_middlware(application)
Call a background task in Django view:
from django_simple_task import defer def task1(): time.sleep(1) print("task1 done") async def task2(): await asyncio.sleep(1) print("task2 done") def view(requests): defer(task1) defer(task2) return HttpResponse(b"My View")
It is required to run Django with ASGI server. Official Doc
