Activities Admin Page - Fixes Summary

Issues Fixed

1. ✅ AI Parsing Not Working

Problem: AI-generated JSON was appearing as raw text in form fields instead of being parsed.

Solution:

• Added defensive JSON parsing to handle cases where API returns JSON as a string
• Improved error handling with detailed error messages
• Added console logging for debugging
• Enhanced toast notifications with proper durations

Files Modified:

• frontend/src/pages/admin/AdminActivitiesPage.tsx (lines 195-217)

2. ✅ Map Integration Fixed

Problem:

• Map coordinates were not being saved to the event
• Map preview was not showing after import
• "Poloha nebyla nalezena" error when location wasn't geocoded

Solution:

• Added latitude and longitude fields to Event model (backend)
• Updated EventInput to accept coordinates
• Modified CreateEvent and UpdateEvent controllers to save coordinates
• Added map preview after importing coordinates
• Coordinates are now saved when using MapLinkImporter
• EventLocationMap component now accepts and uses stored coordinates (falls back to geocoding if not provided)

Files Modified:

• internal/models/event.go - Added YoutubeURL, Latitude, Longitude fields
• internal/controllers/event_controller.go - Added fields to EventInput, CreateEvent, UpdateEvent
• frontend/src/types/event.ts - Added latitude, longitude fields
• frontend/src/pages/admin/AdminActivitiesPage.tsx - Save coordinates on import, show map preview
• frontend/src/components/events/EventLocationMap.tsx - Accept and use provided coordinates
• frontend/src/pages/ActivityDetailPage.tsx - Pass coordinates to map component

3. ✅ YouTube Video Embed Fixed

Problem: YouTube videos were not displaying correctly due to complex/broken URL parsing.

Solution:

• Created robust getYouTubeEmbedUrl() helper function that handles:
  • Standard watch URLs: https://www.youtube.com/watch?v=VIDEO_ID
  • Short URLs: https://youtu.be/VIDEO_ID
  • Embed URLs: https://www.youtube.com/embed/VIDEO_ID
  • Already embedded URLs (returns as-is)
• Properly extracts video ID using regex matching
• Returns null for invalid URLs

Files Modified:

• frontend/src/pages/ActivityDetailPage.tsx - Added getYouTubeEmbedUrl helper (lines 37-72)

---

4. ✅ File Attachments - Supported Formats

Problem: No file type restrictions or information about supported formats.

Solution:

• Added visible list of supported file formats above upload button
• Implemented file type validation with user-friendly error messages
• Added accept attribute to file input for browser-level filtering
• Shows individual error messages for each failed upload

Supported Formats:

• Documents: PDF, Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint (.ppt, .pptx)
• Images: JPG, JPEG, PNG, GIF, WEBP
• Text: TXT
• Archives: ZIP, RAR

Files Modified:

• frontend/src/pages/admin/AdminActivitiesPage.tsx - Added file type validation (lines 864-910)

---

Database Schema Changes

The following fields were added to the events table (via AutoMigrate):

• youtube_url VARCHAR(500) - Stores YouTube video URL
• latitude FLOAT - Stores location latitude (nullable)
• longitude FLOAT - Stores location longitude (nullable)

Note: AutoMigrate is called on every CreateEvent/UpdateEvent operation, so the schema will update automatically when the server restarts.

Testing Checklist

AI Generation

• Test AI generation with various prompts
• Verify title and description fields are populated correctly
• Test with "Přepsat existující obsah" checkbox on/off
• Verify different tone settings work

Map Integration

• Import coordinates from Google Maps link
• Import coordinates from Mapy.cz link
• Verify map preview shows after import
• Create event and verify coordinates are saved
• Edit existing event - verify map loads with saved coordinates
• View event detail page - verify map shows correctly

YouTube Videos

• Add YouTube video using standard watch URL
• Add YouTube video using short youtu.be URL
• Add YouTube video from club channel selector
• View event detail page - verify video embeds correctly
• Test with various YouTube URL formats

File Attachments

• Upload supported file types (PDF, Word, Excel, etc.)
• Try uploading unsupported file type - verify error message
• Upload multiple files at once
• Verify file list shows with correct sizes
• Remove attachment - verify it's removed from list

Form Validation

• Try submitting without required fields - verify error messages
• Verify "Název" and "Začátek" show required field errors

Next Steps

1. Backend: Restart the Go server to apply database schema changes
2. Frontend: Rebuild the React app if needed
3. Testing: Run through the testing checklist above
4. Monitoring: Check server logs for any migration warnings or errors

• Improved error messages throughout the form
• Better loading states and user feedback
• Consistent toast notification durations
