Description

Following successful completion of all prerequisite steps, when I run the database migrations, I get the following error:

[root@localhost netbox]# python3 manage.py migrate
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

ImportError: Could not import 'utilities.api.TokenAuthentication' for API setting 'DEFAULT_AUTHENTICATION_CLASSES'. ImportError: cannot import name 'is_authenticated'.

I also got the same exact error when running Python 3.6.2.

This is fixed in develop (was reported in #1563) - downgrading the djangorestframework dependency to 3.6.4 should resolve it for you on 2.1.5.
