Django Apps aren't loaded yet error

Question

I'm still new to Django, but when I run python manage.py runserver, I get this error:

Unhandled exception in thread started by <function wrapper at 0x10363f2a8>
Traceback (most recent call last):

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

Does this mean that the problem is with INSTALLED_APPS? toa is the name of the app, and toa.models.absolutedollarvalue is the name of one of the tables in models.py.

Can anyone tell me what my issue is? This is my settings.py:

I'm trying to query the database in my views.py and then pass it to a template to display using highcharts.js. However, the server won't run right now, so I can't figure out if my queries are working or if they're even displaying properly.

Please let me know if you need anymore information.

Would really appreciate any help. Thanks!

Answer 1

You have to leave toa.models.Absolutedollarvalue out of your INSTALLED_APPS, it is loaded during the load of your toa app (the line above it) You do not have to load your files within your app individually. You are now trying to load your model as an individual app.

If toa is a python/django lib you haven't written, then it might be caused due to a version incompatibility issue
