Getting it to work in modern Django

This was a question, but now it's just a guide for anyone trying to get this code imported onto their local machine with a modern version of everything. It took me too long to figure this out, and I hope anyone following along can save themselves time with this little guide.

Change your urls to path. You need to change your import as well as default regex.

from django.urls import path, include
from django.contrib import admin


urlpatterns = [

    path('admin/', admin.site.urls),

    path('api-auth/', include('rest_framework.urls',
                             namespace='rest_framework')),

]

Next, in settings.py.

1) Change MIDDLEWARE_CLASSES to MIDDLEWARE. This was change in Django 2.0 I believe.

2) Remove SessionAuthenticationMiddleware from the MIDDLEWARE list. This is enabled by default since Django 1.10

Finally, in models.py

Anything that uses a ForeignKey needs to have the mandatory on_delete default setting. So in your Review class:

class Review(models.Model):

    course = models.ForeignKey(Course, related_name='reviews', on_delete=models.CASCADE)

I believe that's it.
