Theme Song Booth

Version: v0.5.6

A Flask web application for running a convention booth where visitors request a custom AI-generated theme song. Operators manage the queue from an admin dashboard, generate Suno prompts, upload MP3 previews, collect payment, and deliver final songs by email.

What the booth does

1. A visitor fills out a short form at /request.
2. The operator reviews the request in the admin dashboard and generates a Suno Custom Mode prompt.
3. The operator (or an AI assistant via the /api/prompt callback) saves the prompt to the request.
4. The operator creates two song versions in Suno, downloads them, and uploads Version A and Version B to the request page.
5. The operator sends a preview email; the customer visits their private player page, listens to both versions, and either approves one/both or requests changes.
6. After the customer approves and pays, the operator records the payment reference and delivers the selected MP3(s) by email.
7. Optional stems / extras can be delivered via a share link that appears on the player page after delivery.

Customer-facing pages

Page	Path	Purpose
Request form	/request	Visitors enter email, name, pronouns, hobbies, notable facts, and extra requests. The music style is picked from three dropdowns: Decade (required), Basic style (required), and Additional style (optional). Decades and genres are loaded from /mnt/Storage/Decades.txt and /mnt/Storage/Music Genres.txt. Rate limited to 5 submissions per minute per IP.
Closed page	/request (when booth is closed)	Shows a friendly closed banner instead of the form when the operator marks the booth closed.
Thanks	/thanks/<id>	Confirmation page shown after a request is submitted.
Order status	/status	Customers enter their email to see all their requests and statuses.
FAQ	/faq	Answers common customer questions.
Private player	/play/<token>	Secret link emailed to the customer. Streams Version A and B, lets them approve or request revisions, and later download delivered files / stems.
Kiosk	/kiosk	Public full-screen display for a booth tablet. Cycles between a QR code for /request and the configured price list. Updates automatically when pricing or booth state changes.

Style selection

The request form no longer has a free-text genre field. Instead, customers choose:

1. Decade / era — required (e.g. 1980's).
2. Basic style — required (e.g. Pop).
3. Additional style — optional (e.g. Funk).

These are stored together in the style_genre column as a comma-separated string (e.g. 1980's, Pop, Funk) so no schema change is required. The admin request page shows the same dropdowns for corrections, and the copy-to-Hermes prompt formats the style as a clean sentence like "1980's-era Pop with Funk influences" for better Suno results.

Pronouns

A required Pronouns dropdown is shown just below the name field, with options:

• He/Him/His
• She/Her/Hers
• They/Them/Their

The selected pronouns are stored in the pronouns column and included in confirmation emails and Hermes prompt copy.

Operator / admin pages

Page	Path	Purpose
Login	/admin/login	Simple session-based login. Password comes from the ADMIN_PASSWORD environment variable.
Dashboard	/admin	Main queue. Filter by status and auto-refresh at a configurable interval.
Request detail	/admin/request/<id>	Full control of one request: edit customer info (including pronouns and structured style), save prompt, copy Hermes callback, view revision history, upload MP3s, send preview, record payment, deliver files, add operator notes, and cancel.
Pricing	/admin/pricing	Configure fixed prices (one song, both songs, WAV per song, STEMs per song) and up to 5 custom items.
Sales	/admin/sales	Report of all delivered requests with customer details and Square payment references.
Settings	/admin/settings	Database health, backups, SMTP config, MP3 metadata defaults, revision limit, auto-refresh interval, kiosk mode, booth open/closed switch, Hermes API key management, and system reset.
Reset	/admin/reset	Clears all requests and uploaded files. Requires admin password confirmation.

Settings page explained

The /admin/settings page is split into functional sections:

Booth state

• Booth open / closed — When closed, /request and /kiosk show the closed banner.

Hermes API key

• Displays whether a key is configured.
• Regenerate API Key creates a new random key stored in runtime settings.
• The key is used by the /api/prompt/<id> callback and by the /api/key-test diagnostic endpoint.
• Copy this key into your Hermes skill or AI assistant config.

Customer revision limit

• Maximum number of times a customer can click Request Changes on the player page.
• Default is controlled by MAX_REVISIONS env var; can be overridden here.

Dashboard refresh

• How often /admin reloads automatically (10, 20, or 30 seconds).

Kiosk display

• QR only — shows the QR code permanently.
• Pricing only — shows the price list permanently.
• Cycle every N seconds — alternates between QR and pricing.

SMTP settings

• Host, port, username, from address, and password for sending customer emails.
• The password is encrypted using APP_SECRET_KEY before being saved.
• Send Test Email verifies the configuration.

MP3 metadata defaults

• Artist, album, year, and comment tags applied automatically to uploaded MP3s.
• The title tag is taken from the saved Suno prompt.

Database maintenance

• Health Check — verifies all expected tables and columns exist.
• Fix Database Schema — adds missing tables/columns without deleting data.
• Download Database Backup — downloads the SQLite file.
• Restore Database Backup — replaces the live DB with an uploaded backup.
• Download Uploads Backup — ZIPs all uploaded MP3s for offline storage.
• System Reset — deletes all requests and uploaded files for a fresh event.

Docker installation

1. Prepare environment variables

Generate values for the required secrets:

python3 -c "import secrets; print(secrets.token_hex(32))"

Use the output for APP_SECRET_KEY.

2. Deploy with Portainer

1. Log in to Portainer.
2. Go to Stacks → Add stack.
3. Choose Repository:
   • URL: https://gitlab.hallsworth.ca/yrtria/theme-song-booth.git
   • Branch: main
   • Compose path: docker-compose.yml
4. Add the environment variables listed in the section below.
5. Deploy the stack.
6. Open a console in the running theme-song-booth container and run once:

python init_db.py

7. Point your reverse proxy at the host port you chose (default 127.0.0.1:8000).
8. Visit /admin/settings and click Regenerate API Key.
9. Copy the key to your Hermes skill / AI assistant.
10. Print or display a QR code pointing to https://your-domain/request.

Updating the deployment

After each push to Gitea:

Portainer → Stacks → theme-song-booth → Pull and redeploy

Persistent volumes keep the database and uploads safe across redeploys.

Common troubleshooting

Problem	Cause	Fix
Emails not arriving	SMTP settings wrong or messages in spam.	Use Send Test Email on /admin/settings; verify host/port/password.
Can't reach app through domain	Reverse proxy points to wrong host port.	Match HOST_PORT to your proxy upstream.
Static banner not showing	Browser cached old image.	Hard-refresh or redeploy stack.
Logo missing from email	Logo file missing from static/.	Ensure static/DM-Logo_email.png is in the container.
Database schema mismatch	New column/table added but old DB not migrated.	Go to /admin/settings and click Fix Database Schema, or run python init_db.py.
Kiosk shows old prices	Page auto-refreshes every 30s; check /admin/pricing.	Verify pricing values and redeploy if templates changed.
/api/prompt returns 401	Callback token expired or API key mismatch.	Copy a fresh callback URL from /admin/request/<id> and verify the key with /api/key-test.
