Flask To-Do App with User-Based Task Management

A simple to-do app built with Flask and Flask-SQLAlchemy. Each user logs in with a username and sees only their own tasks, stored in a relational database.

Features

• User-based task management without password authentication
• Relational database with Users and Tasks tables
• Each task is linked to a user via a foreign key
• Automatic user creation on login if username does not exist
• Persistent storage using Flask-SQLAlchemy

How It Works

1. When a user enters a username:
   • The app checks the Users table.
   • If the user does not exist, a new user is created.
2. The app then queries the Tasks table for any tasks tied to that user.
3. The user can view, add, and delete their own tasks.
