Chuck 24c34c5a40 fix(plugins): Resolve plugin action button errors and config save permission issues (#162)
* fix(plugins): Resolve plugin ID determination error in action buttons

- Fix server-side template parameter order for executePluginAction
- Add data-plugin-id attributes to action buttons in all templates
- Enhance executePluginAction with comprehensive fallback logic
- Support retrieving pluginId from DOM, Alpine context, and config state
- Fixes 'Unable to determine plugin ID' error for Spotify/YouTube auth

* fix(plugins): Add missing button IDs and status divs in server-side action template

- Add action-{id}-{index} IDs to action buttons
- Add action-status-{id}-{index} status divs for each action
- Match client-side template structure for consistency
- Fixes 'Action elements not found' error

* fix(api): Fix indentation error in execute_plugin_action function

- Fix incorrect else block indentation that caused 500 errors
- Correct indentation for OAuth flow and simple script execution paths
- Resolves syntax error preventing plugin actions from executing

* fix(api): Improve error handling for plugin actions and config saves

- Add better JSON parsing error handling with request details
- Add detailed permission error messages for secrets file saves
- Include file path and permission status in error responses
- Helps diagnose 400 errors on action execution and 500 errors on config saves

* fix(api): Add detailed permission error handling for secrets config saves

- Add PermissionError-specific handling with permission checks
- Include directory and file permission status in error logs
- Provide more helpful error messages with file paths
- Helps diagnose permission issues when saving config_secrets.json

* fix(config): Add permission check and actionable error message for config saves

- Check file writability before attempting write
- Show file owner and current permissions in error message
- Provide exact command to fix permissions (chown + chmod)
- Helps diagnose and resolve permission issues with config_secrets.json

* fix(config): Preserve detailed permission error messages

- Handle PermissionError separately to preserve detailed error messages
- Ensure actionable permission fix commands are included in error response
- Prevents detailed error messages from being lost in exception chain

* fix(config): Remove overly strict pre-write permission check

- Remove pre-write file existence/writability check that was blocking valid writes
- Let actual file write operation determine success/failure
- Provide detailed error messages only when write actually fails
- Fixes regression where config_secrets.json saves were blocked unnecessarily

* fix(config): Use atomic writes for config_secrets.json to handle permission issues

- Write to temp file first, then atomically move to final location
- Works even when existing file isn't writable (as long as directory is writable)
- Matches pattern used elsewhere in codebase (disk_cache, atomic_manager)
- Fixes permission errors when saving secrets configuration

* chore: Update music plugin submodule to include live_priority fix

* fix(plugins): Improve plugin ID determination in dynamic button generation

- Update generateFormFromSchema to pass currentPluginConfig?.pluginId and add data attributes
- Update generateSimpleConfigForm to pass currentPluginConfig?.pluginId and add data attributes
- Scope fallback 6 DOM lookup to button context instead of document-wide search
- Ensures correct plugin tab selection when multiple plugins are present
- Maintains existing try/catch error handling and logging

LED Matrix Web Interface V3

Modern, production web interface for controlling the LED Matrix display.

Overview

This directory contains the active V3 web interface with the following features:

  • Real-time display preview via Server-Sent Events (SSE)
  • Plugin management and configuration
  • System monitoring and logs
  • Modern, responsive UI
  • RESTful API

Running the Web Interface

Standalone (Development)

From the project root:

python3 web_interface/start.py

Or using the shell script:

./web_interface/run.sh

As a Service (Production)

The web interface can run as a systemd service that starts automatically based on the web_display_autostart configuration setting:

sudo systemctl start ledmatrix-web
sudo systemctl enable ledmatrix-web  # Start on boot

Accessing the Interface

Once running, access the web interface at:

Configuration

The web interface reads configuration from:

  • config/config.json - Main configuration
  • config/secrets.json - API keys and secrets

API Documentation

The V3 API is available at /api/v3/ with the following endpoints:

Configuration

  • GET /api/v3/config/main - Get main configuration
  • POST /api/v3/config/main - Save main configuration
  • GET /api/v3/config/secrets - Get secrets configuration
  • POST /api/v3/config/secrets - Save secrets configuration

Display Control

  • POST /api/v3/display/start - Start display service
  • POST /api/v3/display/stop - Stop display service
  • POST /api/v3/display/restart - Restart display service
  • GET /api/v3/display/status - Get display service status

Plugins

  • GET /api/v3/plugins - List installed plugins
  • GET /api/v3/plugins/<id> - Get plugin details
  • POST /api/v3/plugins/<id>/config - Update plugin configuration

Real-time Streams (SSE)

  • GET /api/v3/stream/stats - System statistics stream
  • GET /api/v3/stream/display - Display preview stream
  • GET /api/v3/stream/logs - Service logs stream

Development

When making changes to the web interface:

  1. Edit files in this directory
  2. Test changes by running python3 web_interface/start.py
  3. Restart the service if running: sudo systemctl restart ledmatrix-web

Notes

  • Templates and static files use the v3/ prefix to allow for future versions
  • The interface uses Flask blueprints for modular organization
  • SSE streams provide real-time updates without polling
