🌐 Introduction to Django

📘 What is Django?

Django is a free, open-source, high-level web framework written in Python.
It encourages rapid development and clean, pragmatic design.

Django makes it easier to build web applications by taking care of much of the hassle of web development.

🔧 Why Use Django?

✅ Key Features:

🏗️ Django Architecture: MVT

Django follows the Model-View-Template (MVT) pattern:

User <--> View (Python Code) <--> Model (Database) <--> Template (HTML)

🚀 How Django Works (Basic Flow)

1. User types a URL in the browser.
2. URL Dispatcher finds the correct view function.
3. View fetches data using Model.
4. Passes data to the Template.
5. Template renders the page.
6. Response goes back to the user.

📦 Installing Django

✅ Requirements:

• Python 3.x
• pip (Python package installer)

🔧 Installation:

pip install django

✅ Verify Django Version:

django-admin --version

🛠️ Creating Your First Django Project

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

🧩 Creating a Django App

Apps are reusable modules. For example: blog, shop, accounts, etc.

python manage.py startapp blog

Then, add the app to INSTALLED_APPS in settings.py:

INSTALLED_APPS = [
    'blog',
    ...
]

📄 Django Project Structure

│   └── wsgi.py
├── blog/
│   ├── models.py
│   ├── views.py
│   └── templates/

🔗 Creating Your First URL & View

Step 1: Add a view in blog/views.py

from django.http import HttpResponse

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

Step 2: Add URL in blog/urls.py (create if not exists)

from django.urls import path
from . import views

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

Step 3: Include in main urls.py

from django.urls import include, path

urlpatterns = [
    path('', include('blog.urls')),
]
