I have a use case, where I need to import some of my django models inside the celery.py file in a django-celery standard project.

My project looks like follows:

|-- backend
| |-- backend
| | |-- __init__.py
| | |-- celery.py
| | |-- settings.py
| | |-- urls.py
| | `-- wsgi.py
| |-- bobbers
| | |-- __init__.py
| | |-- admin.py
| | |-- apps.py
| | |-- models.py
| | |-- serializers.py
| | |-- tests.py
| | |-- urls.py
| | `-- views.py
| |-- manage.py
| |-- requirements.txt

All the contents of the celery related files (backend/backend/__init__.py, and backend/backend/celery.py) are exactly as indicated in the official docs.

But once I add the line import bobbers.models as bobber_models to my celery.py file, I get the infamous AppRegistryNotReady error with the following stacktrace:

 File "/usr/local/lib/python3.7/site-packages/django/db/models/base.py", line 87, in __new__
 app_config = apps.get_containing_app_config(module)
 File "/usr/local/lib/python3.7/site-packages/django/apps/registry.py", line 249, in get_containing_app_config
 self.check_apps_ready()
 File "/usr/local/lib/python3.7/site-packages/django/apps/registry.py", line 132, in check_apps_ready
 raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

Needless to say, if I remove the import, all goes well.

So how can I safely import django models in the same file where I write my celery tasks?
