I am total new to Python and its frameworks. Just trying some hands on Django after some Python fundamentals.
Problem:
Right now I am trying to run Django server after first installation. The server runs without any error but when I try to visit the web page I get 503 Service Unavailable Error on http://127.0.0.1:8000/ and the server shuts down automatically.
Server Runs but errors after request:
D:\Code\Outer_Dir>manage.py runserver

Django version 1.6.1, using settings 'mysite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.
