Error "imported before its application was loaded"

[ckcollab]

Heyo! First of all: thanks for all of the hard work.

I'm trying to setup github oauth in my Django app, but I am getting this strange error...

RuntimeError: Model class social.apps.django_app.default.models.UserSocialAuth doesn't declare an explicit app_label and either isn't in an application in INSTALLED_APPS or else was imported before its application was loaded. 

I have the right stuff in installed apps (I believe) 'social.apps.django_app.default'

And I know I just recently used python-social-auth with 0 problems in another project, so I'm not sure what I may be doing wrong. I'm pretty confused because I see issues with people getting the same error (but as a warning?) and it seems to have been fixed?

Here's the complete error:

Hrm, I downgraded to Django 1.8 and I'm getting this
backend not found

When requesting http://localhost:8000/login/github/ OR http://localhost:8000/login/github-oauth2/

Using:

AUTHENTICATION_BACKENDS = (
    'social.backends.github.GithubOAuth2',
    'django.contrib.auth.backends.ModelBackend',
)

and

INSTALLED_APPS = (
    ...
    'social.apps.django_app.default',
)

NOTE: For anyone who runs into this again.............. make sure you're working on the right settings.py ;)
