Re: whats the use of setting mysite.settings to DJANGO_SETTINGS_MODULE?

This is done so that when you run the script manage.py (that runs django commands) the module django imported by the script knows which project settings to use.

If you do not provide this, django will not recognize the apps you are developing, and will just recognize the default apps it comes bundled with.
