Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It's a powerful and flexible tool for building web applications quickly and efficiently.
Features
- MVC Architecture: Django follows the Model-View-Controller architectural pattern, making it easier to manage the codebase.
- ORM (Object-Relational Mapping): Django comes with a built-in ORM that allows you to interact with the database using Python code.
- Rich set of built-in features: Django provides a wide range of built-in features like authentication, sessions, and user management.
- Extensibility: You can extend Django with various third-party packages to add additional functionality.
Getting Started
To get started with Django, you need to install it first. You can do so using pip:
pip install django
Once installed, you can create a new Django project by running:
django-admin startproject myproject
This will create a new directory with all the necessary files to start a new project.
Creating an App
After creating a project, you can create an app within your project. An app is a collection of Python modules containing all the settings for a particular area of your project.
cd myproject
python manage.py startapp myapp
This will create a new app within your project.
Templates
Django uses templates to generate HTML content. You can create templates using the Django templating language.
<!DOCTYPE html>
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<h1>Welcome to my website!</h1>
</body>
</html>
Models
Django models are Python classes that map to database tables. You can define models using the following syntax:
from django.db import models
class Article(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
Views
Django views are functions that handle requests and return responses. You can define views using the following syntax:
from django.http import HttpResponse
def home(request):
return HttpResponse("Welcome to my website!")
URL Routing
Django uses URL routing to map URLs to views. You can define routes in your urls.py
file:
from django.urls import path
from . import views
urlpatterns = [
path('', views.home, name='home'),
]
Deploying
To deploy a Django application, you can use various platforms like Heroku, AWS, or DigitalOcean.
