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
I get the same error and I don´t know how to figure out this problem. It took me many hours to notice that I have a init.py at the same direcory as the manage.py from django.
Before:
|-- myproject
|-- __init__.py
|-- manage.py
|-- myproject
|-- ...
|-- app1
|-- models.py
|-- app2
|-- models.py
After:
|-- myproject
|-- manage.py
|-- myproject
|-- ...
|-- app1
|-- models.py
|-- app2
|-- models.py
It is quite confused that you get this "doesn't declare an explicit app_label" error. But deleting this init file solved my problem.
