Friend List App

A Ruby on Rails web application for managing your personal friend list. Users can sign up, log in, and manage their own contacts — each user only sees and controls their own friends.

Live app: https://friend-list-app-0a3b2c1a2f33.herokuapp.com

Features

• User authentication with Devise (sign up, log in, sign out, delete account)
• Add, show, edit, and delete friends
• Each user has their own private, secured friends' list
• Authorization — users can only view and edit their own friends
• Responsive UI with Bootstrap

What I Explored

This is my first Ruby on Rails project. Building it taught me:

• How Rails MVC architecture works (models, views, controllers)
• Setting up user authentication with Devise
• Creating and running database migrations
• Building CRUD functionality with Rails scaffolding
• Associating users with their own data using model associations
• Securing authorization so users can only view and edit their own friends
• Writing model and controller tests
• Using Bootstrap for a responsive UI
• Deployment to Heroku with PostgreSQL

Tech Stack

• Ruby on Rails 8.1
• PostgreSQL
• Devise
• Hotwire (Turbo + Stimulus)
• Bootstrap

Prerequisites

• Ruby 3.x+
• Ruby on Rails 8.1
• PostgreSQL
• Bundler (gem install bundler)

Getting Started

Clone the repo:

git clone git@github.com:lillysilly3/friend_list_app.git
cd friend_list_app

Install dependencies:

bundle install

Make sure PostgreSQL is running, then set up the database:

rails db:create
rails db:migrate

Start the server:

rails server

Then open http://localhost:3000 in your browser.

Future Ideas

• Add a notes/bio field for each friend
• Birthday reminders
• Search/filter friends by name
• Card view instead of a table
