Django model “doesn't declare an explicit app_label”

Question

I\'m at wit\'s end. After a dozen hours of troubleshooting, probably more, I thought I was finally in business, but then I got:

Model class django.contrib.co         


        

Answer 1

The issue is that:

1. You have made modifications to your models file, but not addedd them yet to the DB, but you are trying to run Python manage.py runserver.

2. Run Python manage.py makemigrations

3. Python manage.py migrate

4. Now Python manage.py runserver and all should be fine.
