Features

Tournament Management

Creating a Tournament

1. Navigate to Admin Dashboard (/admin)
2. Click "Create Tournament"
3. Enter tournament details:
   • Name
   • Format (round-robin, single elimination, double elimination, Swiss)
   • Number of teams/players
4. Register participants
5. Generate schedule
6. Record match results

Tournament Formats

• Round-Robin: Each team plays every other team once
• Single Elimination: Lose once and you're out
• Double Elimination: Must lose twice to be eliminated
• Swiss: Pairings based on win-loss records

Partnership Analytics

Tracking Partnerships

The system automatically tracks:

• Games played together
• Win/loss records
• Elo changes per partnership
• Partnership win rates

Viewing Partnership Data

1. Visit any player's profile page (/players/:id/profile)
2. Scroll to "Partnership Performance" section
3. View statistics for each partner

Player Profiles

Each player profile displays:

• Current Elo rating
• Total games played
• Win rate
• Partnership statistics
• Recent games timeline

Admin Dashboard

The admin dashboard provides:

• Quick statistics (total players, active tournaments, recent matches)
• Quick action buttons for common tasks
• Recent matches table
• Links to all admin sections

Authentication & Authorization

User Roles

Role	Permissions
Player	Edit own profile, record own matches within 5 minutes
Tournament Admin	Create/manage tournaments, edit matches in their tournaments (no time limit)
Club Admin	Full access to edit/delete any record, manage all players and tournaments

Login/Logout

Login:

• Navigate to /login
• Enter email and password
• Click "Login"

Logout:

• Click "Logout" in navigation bar

Admin User Creation

To create an admin user, use the provided script:

ruby scripts/create_admin.rb <email> <password>

Example:

ruby scripts/create_admin.rb david@dhg.lol admin

This will:

1. Create a player profile
2. Create a user account with club_admin role
3. Mark the account as confirmed

Manual SQL Alternative:

If you prefer to create users manually via SQL:

1. Access the database: sqlite3 db/euchre_camp.db
2. Generate a BCrypt password hash:

   ruby -e "require 'bcrypt'; puts BCrypt::Password.create('your_password')"
   

3. Insert a user record:

   INSERT INTO players (name, rating) VALUES ('PlayerName', 1000);
   INSERT INTO users (player_id, email, password_digest, role, confirmed, created_at, updated_at)
   VALUES (1, 'user@example.com', '$2b$12$...', 'club_admin', 1, datetime('now'), datetime('now'));

• Check user role in database

Debugging

Check server logs:

tail -f /tmp/puma.log

Check database:

sqlite3 db/euchre_camp.db
sqlite> .tables
sqlite> SELECT * FROM users;
