Django import my app models AppRegistryNotReady

Question

I will import my models in celery.py. But when I import and run the runserver command, I get the following error:

  File "/directory/manage.py", line 22, in <module>
    main()
  File "/directory/manage.py", line 18, in main

    raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

My import code line in celery.py: from app.models import model1, model2

You can try adding this line to your settings.py file:

import django
django.setup()

See here for solution.

if it doesn't work, this might be what you need:

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "your_project.settings")

and these lines:

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

If the first solution doesn't work here the alternative solution.

Finally, there is such a solution:

import django

# some variable declarations    
world_mapping = {
    'osm_id': 'osm_id',
}    

if __name__ == '__main__':
    django.setup()
    # import AFTER setup
    from app.models import WorldBorder
    # from now I can access WorldBorder!!

I solved it by copying all tasks from celery.py to app tasks.py.

It also fixes itself when I delete celery related lines from __init__.py file.
