• 5000 feet overview of How Django Works
• Steps:
  • Browser sends the request
  • Webserver recieves the requst and hands over the request to WSGI server
  • WSGI can run python applications. The request with necessary information (environ) and optionally passes through layers of middleware and ultimately will reach your django application
  • URL configuration selects a view to handle the request
  • The view might do the following
    • Talk to the database or any external API
    • Renders the HTML
    • Returns the respons
    • Raise an error
  • The HttpResponse created will leave the Django application to WebServer and reach browser to render the WebPage
