django-simple-task's Issues
Daphne not working with django-simple-task?
If I run a fairly simple django app (which I'll try to get pushed to a sample repo on github at some point) that follows your instructions, when running the django app via Daphne, Daphne doesn't send a scope["type"] == lifetime event, and as a result, the queue/loop values don't get set, so when defer is called, the loop doesn't get used and the function just finishes (so the deferred "func" isn't called); swapping uvicorn for Daphne and django-simple-task works as advertised. Reading quickly the ASGI spec, I think Daphne isn't following the suggested lifetime bit, but I could be missing something. Anyways, I would suggest:
A) If you've tested it with Daphne, documenting any extra steps required
B) If I'm correct and uvicorn is doing the asgi spec the way django-simple-task expects, recommend using that.
C) Modifying task.py's defer so that if loop isn't defined, it at least logs that there was no queue to save this func to run (or possibly just call the func inline?)
Django-4.1 Warning - Tests for Python-3.10 and Django-4.0
The following deprecation warning appears for:
RemovedInDjango41Warning:
'django_simple_task' defines default_app_config = 'django_simple_task.apps.DjangoSimpleTaskConfig'.
Django now detects this configuration automatically. You can remove default_app_config.
app_config = AppConfig.create(entry)
Will django-simple-task run for Django-4.0 and Python-3.10?

Feature Request： Cronjob/celerybeat
can we do something to impl this func？
my use the call_later?
I follow the docs example,but task is not running
System:
- MacOX
Requirement: - Django==3.0.1
- daphne==2.4.1
StartCommand: - daphne src.asgi:application
Description: - When I visit localhost:8000/test,the task is not running.
# asgi.py
import os
from django.core.asgi import get_asgi_application
from django_simple_task import django_simple_task_middlware
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'src.settings')
application = get_asgi_application()
application = django_simple_task_middlware(application)# views.py
import time
from django.shortcuts import HttpResponse
from django_simple_task import defer
def task1():
time.sleep(1)
print("task1 done")
def view1(requests):
defer(task1)
return HttpResponse("My View")# urls.py
from django.contrib import admin
from django.urls import path
from app01 import views
urlpatterns = [
path('admin/', admin.site.urls),
path("test", views.view1)
]No output with example code in Daphne
Thanks for an interesting project! Perhaps I've missed something, but using the current example in the docs doesn't seem to output or execute the deferred functions when using Daphne, but does with Uvicorn.
Using:
- Python: 3.8.0
- Django: 3.0.1
- uvicorn 0.11.1 vs. daphne 2.4.1
- django-simple-task: 0.1.1
uvicorn's output:
$ uvicorn --log-level debug background_tasks_test.asgi:application
