With Python 2.7.x + Django 1.9:

I create a new super-simple Django skeleton project with `django-admin startproject simple`

As a sanity check, I create a `views.py` file with a simple view that outputs a "hello world" type test message and a url route to that view. I can run this with `python manage.py runserver` and it works fine.

I create a `models.py` file with a single super simple Django ORM model class. FYI, my goal is to use existing tables and schema, so I don't want the ORM to generate new tables.

```
class SuperSimpleModel(models.Model):
    some_value = models.CharField(blank=True, null=True)

    class Meta:
        managed = False
        db_table = 'model_test_table'

```

Merely adding `import models` to my `views.py` code causes the following error to happen on server startup with `python manage.py runserver`:

> 
> "RuntimeError: Model class simple.models.SuperSimpleModel doesn't declare an explicit app\_label and either isn't
>  in an application in INSTALLED\_APPS or else was imported before its
>  application was loaded."
> 
> 
> 

I presume that my application isn't initializing correctly? I have boiled this problem down to the above simple set of reproducible steps. I haven't changed anything in `settings.py` in the above steps. Normally, I would need to configure the database, but I can reproduce the error without even doing that.
