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()

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

Answer 1

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.
