Deploying Django Project

Deploying a Django project means making your web application live on the internet so users can access it.

After building your project locally, deployment allows it to run on a production server.

Development vs Production

Development:

• Runs on local machine
• Uses built-in Django server
• Used for testing

Production:

• Hosted on a live server
• Uses production web server
• Accessible worldwide

You should never use runserver for production.

Step 1: Prepare Your Project for Deployment

1. Set DEBUG to False

In settings.py:

DEBUG = False

2. Add Allowed Hosts

ALLOWED_HOSTS = ['yourdomain.com', 'www.yourdomain.com']

This prevents security issues.

3. Configure Static Files

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

Then collect static files:

python manage.py collectstatic

Step 2: Choose a Hosting Platform

Popular platforms for deploying Django:

• Heroku
• PythonAnywhere
• DigitalOcean
• AWS (Amazon Web Services)
• Render
• VPS Hosting

Choose based on budget and project size.

Step 3: Use Production Server (Gunicorn)

Install Gunicorn:

pip install gunicorn

Run project using Gunicorn:

gunicorn myproject.wsgi

Gunicorn acts as a production web server for Django.

Step 4: Use Nginx (Optional but Recommended)

Nginx is used to:

• Handle static files
• Manage traffic
• Improve performance
• Add security

Production architecture:

User → Nginx → Gunicorn → Django → Database

Step 5: Configure Database

In production, use:

• PostgreSQL (recommended)
• MySQL

Avoid using SQLite for large production systems.

Example PostgreSQL configuration:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'dbname',
        'USER': 'dbuser',
        'PASSWORD': 'password',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

Step 6: Environment Variables

Do not hard-code sensitive data.

Use environment variables for:

• SECRET_KEY
• Database credentials
• API keys

Example:

import os
SECRET_KEY = os.environ.get('SECRET_KEY')

Step 7: Migrate Database on Server

After deployment:

python manage.py migrate

Create superuser:

python manage.py createsuperuser

Step 8: Enable HTTPS

Use SSL certificate for secure connection.

HTTPS:

• Encrypts data
• Protects users
• Required for production apps

Let’s Encrypt provides free SSL certificates.

Common Deployment Files

requirements.txt → List of project dependencies
Procfile → Used in Heroku
.env → Environment variables file

Create requirements file:

pip freeze > requirements.txt

Deployment Checklist

Set DEBUG = False
Add ALLOWED_HOSTS
Configure database
Configure static files
Use Gunicorn
Use Nginx
Use environment variables
Enable HTTPS

Why Deployment Knowledge is Important

Deployment helps you:

Launch real-world applications
Share projects with clients
Build production-ready systems
Understand server management
Work as a professional developer

Key Takeaway

Deploying a Django project involves configuring production settings, choosing a hosting platform, setting up a production server like Gunicorn, managing static files, securing data, and connecting a production database.

Proper deployment ensures your application is secure, scalable, and accessible to users worldwide.
