Introduction to Django

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It follows the MVT (Model–View–Template) pattern and ships with an ORM, URL routing, templates, forms, authentication, and an auto-generated admin.

MVT Flow

HTTP request → URLConf (urls.py) → View
View ↔ Model (models.py) via ORM
View → Template (.html) → HTTP response

Setting Up Your Environment

Install Python 3.10+ from python.org
Create venv:python -m venv .venv
Activate (Windows):.venv\Scripts\activate
Activate (macOS/Linux):source .venv/bin/activate
Install Django:pip install django
Create project:django-admin startproject mysite .
Run server:python manage.py runserver →

Project Structure

mysite/
├── manage.py
├── mysite/              # Django config package: settings.py / urls.py / wsgi.py / asgi.py
└── core/                # app package (run: python manage.py startapp core)
    ├── models.py        # DB schema & ORM models
    ├── views.py         # Request handlers / controller logic
    ├── urls.py          # (optional) app-level route map
    └── templates/       # HTML templates used by this app

Your First View & Template

Create an app and a simple view that renders a template.

# create an app
python manage.py startapp core

# core/views.py
from django.shortcuts import render

def home(request):
    return render(request, "home.html", {"name": "Django"})

# mysite/urls.py
from django.contrib import admin
from django.urls import path
from core.views import home

urlpatterns = [
    path("admin/", admin.site.urls),
    path("", home, name="home"),
]
