django-admin

  • manage.py is a wrapper around django-admin. Use this as this considers the project's settings.
  • python manage.py runserver to run the server
  • By default, installed apps for admin, auth, messages and staticfiles

Apps in django

• created app has admin module, apps (config), models, tests and view (request handler).
• Function definition for request hanling in views.py.
• URL mapping to function in new file by name urls.py (by convention) with array parameter urlpatterns
• ALWAYS end the route (url) with a forward slash "/"
