• School portals
• E-commerce platforms

4. How Django Works (Simple Idea)

Django follows a structure called MVT (Model, View, Template)

4

a. Model

• Handles data (database)
• Example: users, products, courses

b. View

• Contains logic
• Decides what happens when a request is made

c. Template

• What users see (HTML pages)

5. Installing Django

First install Python, then:

pip install django

Check version:

django-admin --version

6. Creating Your First Django Project

django-admin startproject myproject
cd myproject
python manage.py runserver

👉 Open browser:
http://127.0.0.1:8000

7. Django Project Structure (Simple)

• manage.py → controls the project
• settings.py → project settings
• urls.py → links pages
• views.py → logic
• models.py → database

8. Creating an App in Django

python manage.py startapp myapp

👉 Django projects are made of apps

9. Simple View Example

from django.http import HttpResponse

def home(request):
    return HttpResponse("Hello, Django!")

10. URL Routing

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home),
]

👉 This connects URL to your function.

11. Templates (HTML in Django)

<h1>Welcome to My Site</h1>
<p>This is a Django page.</p>

👉 Django uses HTML for frontend.

12. Django Admin Panel (Powerful Feature)

One of Django’s strongest features:

python manage.py createsuperuser

👉 You get a ready-made admin dashboard to:

• Manage users
• Add data
• Control your website

13. Django vs Basic Web Development
