Django Demo for Hostim.dev

This is a Django application that demonstrates a user management system with several key features:

What it does

• Creates and lists users
• Supports avatar image uploads
• Uses MySQL for the database
• Uses Redis for caching
• Runs in Docker containers

Tech used

• Python with Django 5.2
• MySQL 8.0
• Redis 7
• Docker + Docker Compose
• Django templates

How it's organized

• core/models.py - Defines the UserProfile model
• core/forms.py - Contains UserCreationForm for adding users
• core/views.py - Includes view functions for user management
• core/urls.py - Defines URL routing for the app
• docker-compose.yml - Configures three services: web, MySQL, and Redis
• Dockerfile - Builds the Django app container

Key Features

User Management

The application has a custom user management system that extends Django's built-in User model with a UserProfile model that includes:

• Avatar images (stored in media/avatars/)
• User status tracking

Caching with Redis

The application uses Redis for caching user data:

• The user_management view in core/views.py first checks the Redis cache
• If data isn't cached, it pulls from the database and caches it
• The cache is invalidated when new users are added

Database Integration

The application uses MySQL:

• The app uses MySQL, configured via environment variables (MYSQL_*)
• Migrations are automatically applied at container startup

How to run it

To run the app locally:

docker-compose up --build

Docker Compose sets up three services:

• The web app (Django)
• MySQL
• Redis

The web application will be available at http://localhost:8000/

Notes

• The application uses Django's built-in User model with a custom UserProfile model
• Avatar images are stored in a persistent volume mounted at /app/media
• Database and Redis data are also stored in persistent volumes

This app is also set up for easy deployment on Hostim.dev. It shows how to spin up a full stack app with a database and cache inside containers. For detailed steps on hosting this on Hostim.dev, check out the Hostim.dev deployment guide.
