Any help would be greatly appreciated, let me know if you want to see any other files

It looks like you can't use get_user_model in settings.py. Try to figure out another way to do what you're trying to do there. Can you lazy load it?

[James]

I fixed something similar once by having the model that was causing the problem be set to abstract in its class meta.

Orrrr you need to "makemigrations user" if you've opened up the usermodel and changed a lot of stuff (also had that problem before)

Hope these simple solutions work!

[Leslie Taffe]

Hey so I solved that problem by deleting all the migrations then migrating again to apply changes. now I just need to figure out how to configure the rest of the app to my needs. Do any of you know any up to date repos I could take a look at?
