django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.- django 1.11

Question

After trying to implement Token Authentication using DRF, i get this error raised in my terminal. I have had seen other related relevant questions with solutions but none of them solved my issue.

Below is my wsgi.py

"""
WSGI config for myApp project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/1.11/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myApp.settings")

application = get_wsgi_application()

Try editing your wsgi.py like this,

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()
