π ️ How Django Works (Visual Breakdown)
πΌ️ 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
π¦ Setting Up Django
π§ Step 1: Install Django
pip install django
π§ Step 2: Create a Django Project
django-admin startproject mysite
cd mysite
π§ Step 3: Run the Server
python manage.py runserver
π Visit http://127.0.0.1:8000/
in your browser — you’ll see the Django welcome screen!
π§± 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',
]
π️ Add Your First View
π§Ύ blog/views.py
from django.http import HttpResponse
def home(request):
return HttpResponse("Hello, Django Blog!")
π Map the URL
π§Ύ blog/urls.py (Create this file)
from django.urls import path
from . import views
urlpatterns = [
path('', views.home),
]
π§Ύ 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!"
πΎ Connecting to a Database
Django uses SQLite by default, but you can connect it to PostgreSQL, MySQL, etc.
π§Ύ 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
π ️ Run Migrations
python manage.py makemigrations
python manage.py migrate
π Create and Use the Admin Panel
π€ Create Admin User
python manage.py createsuperuser
Login at http://127.0.0.1:8000/admin/
with your credentials.
π§Ύ blog/admin.py
from django.contrib import admin
from .models import Post
admin.site.register(Post)
πΌ️ Image idea: Screenshot of Django admin panel showing blog posts.
