Using AppConfig to import signals is not working Django 2.08

Question

I have an app companies. Inside the app there is a file called signals.py with the following code:

post_save.connect(update_descendants, sender=Company)

Inside companies apps.py I have:

class CompaniesConfig(AppConfig):
    name = 'apps.companies'

    def ready(self):
        from . import signals

But the signals are not imported/called.

If I import the file in models.py it work but it creates a circular import issue, and I need to this imports inside functions not at top.

Structure:

 - companies
   -apps
   -models
   -signals

Why app config is not working ?

I would say the name has to be without the _apps_ part: `name = 'companies'`. — schrodingerscatcuriosity, Aug 15 '18 at 18:14

If you are using a custom AppConfig class then you need to tell Django about it. It isn't automatically discovered. Reference in in the Django settings files like this:

INSTALLED_APPS [
    ....
    "companies.apps.CompaniesConfig",
    ....
]

You need to add the appconfig in app's init.py:

default_app_config = 'apps.companies.CompaniesConfig'

This is along with the ready() in AppConfig which I see you already have in apps.py

Correction, this should be `default_app_config='companies.apps.CompaniesConfig'` – Martins Dec 31 '21 at 14:46

You may need to add an __init__.py file to the companies directory...

__init__.py can just be a blank file with that name.

it is a package so it has __init___.py – J Mo Aug 16 '18 at 03:50
