Django is a high-level Python web framework that follows a batteries-included philosophy: it ships with an ORM for databases, migrations, URL routing, templates, forms, authentication and an automatic admin interface. It uses a model-view-template pattern, where models define your data as Python classes, views handle requests, and templates render HTML. Django also has strong default protections against common attacks like SQL injection, cross-site scripting and CSRF. Beginners typically follow the official polls tutorial before building their own app. Learnr builds a personalized Django course from your prompt with short, interactive lessons.

How to learn Django, step by step

  1. Get comfortable with Python first. Django code is mostly Python classes and functions, so be fluent with classes, inheritance, modules, dictionaries and virtual environments. Weak Python makes Django errors feel mysterious.
  2. Start a project and run the dev server. In a virtual environment, install Django with pip, run django-admin startproject, then python manage.py runserver. Create an app with startapp and register it in INSTALLED_APPS.
  3. Work through the official tutorial. The polls tutorial in the Django documentation covers models, the admin, views, templates, forms and tests in a sensible order. Type every line yourself rather than copying.
  4. Master models, migrations and the ORM. Define models with fields and relationships like ForeignKey, run makemigrations and migrate, then query with filter, exclude, get and related lookups in the Django shell.
  5. Add forms, users and permissions. Use ModelForm for validation, the built-in auth views for login and logout, and the login_required decorator. Build a notes or recipe app where each user sees only their own records.
  6. Build an API and deploy. Add Django REST Framework for a JSON API, configure static files, set DEBUG to False with real ALLOWED_HOSTS, and deploy. A daily Learnr lesson keeps ORM and view patterns fresh.

What you'll learn

  • Create Django projects and apps and understand how a request is handled
  • Define models and evolve the database with migrations
  • Write views, URL patterns and templates that render data
  • Handle forms, validation, users and authentication
  • Use the admin site and build a REST API with Django REST Framework

What's inside your Django course

A sample path Learnr builds for Django. Your real course adapts to your goal and level.

  • 1. Projects, apps and the request cycle
  • 2. Models, the ORM and migrations
  • 3. Views, URLs and templates
  • 4. Forms, validation and the admin
  • 5. Users, authentication and permissions
  • 6. APIs, static files and deployment

How long does it take to learn Django?

With solid Python, a basic Django app takes about 3 to 6 weeks at 5 hours a week. A complete app with authentication, an API and deployment usually takes 2 to 4 months. If Python is new, plan a couple of months for it first.

What you need before you start

Comfortable Python, including classes and virtual environments, plus basic HTML. Some SQL and HTTP knowledge helps you understand what the ORM and views are doing.

Common mistakes to avoid

  • Editing database tables by hand instead of changing models and running migrations. Keep models as the source of truth and commit migration files.
  • Deploying with DEBUG set to True or the secret key in source code. Load secrets from environment variables and turn debug off in production.
  • Making queries inside loops in templates, causing hundreds of database hits. Use select_related and prefetch_related to fetch related data efficiently.

Django questions, answered

Should I learn Django or Flask?

Flask is minimal and lets you choose your own pieces, which is good for small services and learning internals. Django includes the ORM, admin and authentication, which speeds up building full database-backed sites.

Is Django good for beginners?

Yes, once you know Python basics. Its documentation and official tutorial are thorough, and the built-in admin lets you see your data immediately.

Can Django be used with React?

Yes. A common setup uses Django REST Framework to serve a JSON API and React or another front-end framework to build the interface.
