🧠 What is Django?

Django is a high-level Python web framework that allows you to build secure, scalable, and maintainable web applications quickly.

✅ Motto: “The web framework for perfectionists with deadlines.”

It comes with built-in tools for:

User authentication
Database handling
Admin panels
URL routing
Template rendering

🎯 Why Use Django?

🔐 Secure	Protects against common attacks
🚀 Fast	Built-in admin, ORM, routing
📦 Batteries Included	Everything is included: No need to install many libraries
🌍 Scalable	Used by Instagram, Pinterest, Spotify

🛠️ How Django Works (Visual Breakdown)

🖼️ Image idea: A diagram showing the flow → Browser → URL → View → Model → Template → Response

URLConf: Maps URLs to views
Views: Handle logic and return responses
Models: Define your data structure (database)
Templates: Control how HTML is displayed

📦 Setting Up Django

🔧 Step 1: Install Django

pip install django

🔧 Step 2: Create a Django Project

django-admin startproject mysite
cd mysite

🔧 Step 3: Run the Server

python manage.py runserver

🔗 Visit http://127.0.0.1:8000/ in your browser — you’ll see the Django welcome screen!

🧱 Creating a Simple Django App

Let’s create a blog app.

▶ Step 1: Start the App

python manage.py startapp blog

▶ Step 2: Register the App

Open mysite/settings.py and add 'blog' to INSTALLED_APPS:

INSTALLED_APPS = [
    ...
    'blog',
]

🗂️ Add Your First View

🧾 blog/views.py

from django.http import HttpResponse

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

🔗 Map the URL

🧾 blog/urls.py (Create this file)

from django.urls import path
from . import views

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

🧾 mysite/urls.py (Edit this)

from django.contrib import admin
from django.urls import path, include

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

Now visit http://127.0.0.1:8000/ again → You’ll see: "Hello, Django Blog!"

💾 Connecting to a Database

Django uses SQLite by default, but you can connect it to PostgreSQL, MySQL, etc.

🧾 blog/models.py

from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title

🛠️ Run Migrations

python manage.py makemigrations
python manage.py migrate

📋 Create and Use the Admin Panel

👤 Create Admin User

python manage.py createsuperuser

🧾 blog/admin.py

from django.contrib import admin
from .models import Post

admin.site.register(Post)
