Sometimes you have no clue which settings file is active.

For other files I use this pattern, to see which actual file is loaded:

```
assert 0, mylib.__file__
```

Unfortunately this does not work for `django.conf.settings`:

```
AttributeError: 'Settings' object has no attribute '__file__'
```

It would be super cool, if this attribute would be available.

For other files I use this pattern, to see which actual file is loaded:

{{{
assert 0, mylib.__file__
}}}

{{{
AttributeError: 'Settings' object has no attribute '__file__'

Of course I could use:

{{{
assert 0, os.environ['DJANGO_SETTINGS_MODULE']
}}}

But sometimes the env var is not the actual file.

Comment:

You can use `settings.SETTINGS_MODULE` to check the actual module and
`importlib` to get the file, e.g.
{{{
>>> from django.conf import settings
>>> import importlib
>>> importlib.import_module(settings.SETTINGS_MODULE).__file__
'/django/tests/test_pg.py'
}}}
I don't think that a hook is needed in Django itself.
