Followed 'Writing custom django-admin commands' - 'Apps aren't loaded yet.'!

[paul_d...@hotmail.com]

I've got a basic Django site up and running and am now trying to write a custom command by following the "Writing custom django-admin commands" documentation.  However having followed it carefully I get this exception:

(myfrontier) C:\Users\PDS\git\myfrontier>set DJANGO_SETTINGS_MODULE=myfrontier.settings

(myfrontier) C:\Users\PDS\git\myfrontier>django-admin podcasts

Traceback (most recent call last):

    raise AppRegistryNotReady("Apps aren't loaded yet.")

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

The first two lines of my custom command are just like the example in the doc...

from django.core.management.base import BaseCommand, CommandError

from portal.models import ShowEpisode

So what am I doing wrong?  Is the documentation just wrong?  A quick Google throws up lots of suggestions and a number of people hitting this so can someone from Django dev. give some proper chapter and verse on how to solve this please?

thanks,

Paul DS

Try following this tutorial:

https://simpleisbetterthancomplex.com/tutorial/2018/08/27/how-to-create-custom-django-management-commands.html

It looks like you don't have apps registered in INSTALLED APPS. Also, I always use the 'python manage.py <custom command>' not the 'django-admin <custom command>'
