Hello Pros
I had a project all of a sudden I started seeing this error
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.
i tried fixing it i failed miserably using all stack overflow i came across and django forum. So i started a new project, to see where I got it wrong, a very fresh project but as soon as i added in custom user model, the error wouldn’t allow me even make migrations or migrate
note: this is the only file i have added besides adding in the settings:
