Django

A batteries-included Python web framework for database-backed applications.

Difficulty: intermediateTime: 40+ hours95 of 106 sections written

Django is a Python web framework that turns an incoming HTTP request into a response through a fixed pipeline — routing, a view, an ORM-backed model, and a template — with an admin site, authentication, sessions, and forms all included and wired together from the start.

Why it matters

  • It ships an ORM, admin site, auth, sessions, and templating together, so a database-backed site starts working in minutes, not days of assembling separate libraries.
  • The MTV pattern keeps data, logic, and presentation in separate, independently-testable layers.
  • The auto-generated admin site gives a working internal management UI for free, from the same models the rest of the app already uses.
  • It underpins a large share of production Python web backends, so the patterns here carry directly into real jobs.

Where it is used

  • Content-heavy sites and CMSs — the admin site alone covers a large share of internal tooling needs
  • Database-backed web applications — e-commerce, SaaS dashboards, marketplaces
  • APIs, via Django REST Framework built on top of the same models and views
  • Anywhere a team already knows Python and wants a full-stack framework rather than assembling one

via the ORM

  • Settings — one per project
    • leads to URLconf (ROOT_URLCONF)
  • URLconf — routes requests
    • leads to Apps (dispatches to)
  • Apps — models, views, templates
    • leads to Admin (registers models)
    • leads to Database (reads/writes)
  • Admin — generated from models
  • Database — via the ORM
