Features added: - Course directory scraping with pagination for Swedish courses - Layout scraping from course detail pages (AJAX tabs) - Event results scraping to calculate layout ratings - Mean rating calculation based on players who shot par - Last played date tracking for each layout (extracted from event pages) - Multi-event aggregation for accurate ratings across tournaments Database: - Added courses table (name, link, city, last_updated) - Added layouts table (name, par, mean_rating, rating_count, last_played) - Added database migrations for new columns - Foreign key relationship between courses and layouts API endpoints: - POST /api/scrape-courses - scrape course directory - POST /api/scrape-layouts/:courseId - scrape layouts and events (combined) - POST /api/scrape-all-layouts - bulk scrape all courses - POST /api/scrape-event-results/:courseId - process event results - GET /api/courses - fetch all courses - GET /api/layouts/:courseId - fetch layouts for course UI: - New courses.html page for course/layout management - Expandable course rows showing layouts - Display layout par, mean rating, and last played date - Layouts sorted by most recently played (newest first) - Individual and bulk scraping controls Technical details: - Date extraction using regex pattern matching from event pages - Proper detection of division results in details/table.results structure - Round score and rating extraction from td.round/td.round-rating pairs - Course location from td.views-field-field-course-location 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
