initial setup

[gopalganu]

Do I need to have any basic settings which I need to do after installation?
I have installed Django and templated-email, but when I execute sample code to send a mail, I get the following error. "django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings."

I understand that I may not have done basic configuration, but some help is highly appreciated. New to Django.

Thanks
