post_save signal is not dispatched

[Dejan Spasić]

I don't wont to bother you with a long text and will first show you the code. I think this should be self explanatory. If not, let me know :)

#####################

from typing import Any, Dict

from django.apps import AppConfig
from django.db.models.signals import post_save

from django.contrib.auth.models import User
from .models import Employer


class EmployerConfig(AppConfig):
    name = "employer"
    verbose_name = "Employer"

    def ready(self) -> None:
        def post_save_user(**kwargs: Dict[str, Any]) -> None:
            if kwargs['created']:
                return None

            user: User = kwargs['instance']

            if user.employer:
                return None

            employer = Employer(user=user)
            employer.save()

        post_save.connect(post_save_user, User)
#####################

As you can see I want to create an employer and link them with the new created user. 

Running the command 

./manager.py createsuperuser --username username --email us...@user.com ***********

shows me that I'm wrong. There is no entry in the myapp_employer table. What did I missend?

* Django: 2.0.X 
* app is installed 

* python: 3.6

Hi,

Weirdly, I've just been doing this. What do you have in your settings INSTALLED_APPS? 

One of them should be something like 'employer.apps.EmployerConfig' alternatively in your employer module's __init__.py file you need to say 

default_app_config = 'employer.apps.EmployerConfig'

So for new users, you bail out and do nothing. Your code works exactly as you
wrote it.
