Hi guys !
First of all, i’m new here, so if this issue has already been discussed or
if here is not the place to talk about it (I also opened a forum post
<https://forum.djangoproject.com/t/load-signals-automatically/9666>) please
don’t hesitate to tell me. Also, please be aware English is not my first
language.
I would want to discuss about signals and how they are loaded in Django.
Very often, i create my signals.py, write my signal and wonder for a while
why it does not work. Of course, the file is not imported and so never even
read by python !
So i create an apps.py, on this template :
from django.apps import AppConfig
class CustomAppConfig(AppConfig):
name = "app.subapp"
def ready(self):
import app.subapp.signals
I would like to sugest importing signals.py automatically at app loading
(maybe django.apps.config.AppConfig.ready() ?)
*Pros*
- no more wandering for hours what is the problem here
- no more boilerplate apps.py everywhere
*Cons*
- file with signals would have to be named signals.py
- maybe some rely on the file being imported when they decided ? (don’t
see a use case here, specially when loading signals does not equals
activating them)
*Alternatives*
If loading (and so activating) signals is too mush of a change, maybe
others solutions will fix my problem. For know, all I can think of :
- Log if a signals.py file is detected but the AppConfig is not
overriden (but we would not know if imported elsewhere)
- Log how many signals are detected for the app (but from a dozen apps
the log will be too heavy to be read)
- not really an alternative, but the loading could be conditionnal to a
project-wide setting
i would like to know if this would benefits others (I think so) and if it
is worthy of filing an Issue (as a developper I may find time to dev on it
if needed)
Looking forward to reading from you,
Roxane Bellot
