Django Development Production Settings

I choose the 2nd solution from this post

Dir structure:
[myapp]$ tree
.
├── __init__.py
├── settings
│   ├── __init__.py
│   ├── defaults.py
│   ├── development.py
│   ├── production.py
│   └── staging.py

### __init.py__
from myapp.settings.development import *

### defaults.py
### sensible choices for default settings

### dev.py
from myapp.settings.defaults import *
DEBUG = True
### other development-specific stuff

### production.py
from myapp.settings.defaults import *
DEBUG = False
### other production-specific stuff

### staging.py
from myapp.settings.defaults import *
DEBUG = True
### other staging-specific stuff
