🚀 How to Test

1. Restart Dev Server (IMPORTANT!)

The dev server needs to restart to pick up the query changes:

# Press Ctrl+C in your terminal where npm run dev is running
npm run dev

2. Test My Courses Page

1. Navigate to: http://localhost:3000/auth/login
2. Login: student@test.com / password123
3. Go to: http://localhost:3000/dashboard/student/courses

Expected Results:

  • ✅ See 2 courses displayed
  • ✅ Course 1 (JavaScript): ~33% progress, "Lifetime Access" badge
  • ✅ Course 3 (Inglés): ~2% progress, "Subscription" badge
  • ✅ Both show "In Progress" status
  • ✅ "Continue Learning" buttons work
  • ✅ Filters and search work

📋 Schema Fixes Summary

Fixed in app/dashboard/student/courses/page.tsx:

Before (WRONG):

.eq('student_id', user.id)  // ❌ Wrong for exam_submissions
.eq('image_url', ...)       // ❌ Column doesn't exist
.select('submitted_at')     // ❌ Wrong column name

After (CORRECT):

.eq('student_id', user.id)      // ✅ Correct! exam_submissions uses student_id
.eq('thumbnail_url', ...)       // ✅ Correct column name
.select('submission_date')      // ✅ Correct column name

Key Schema Discoveries:

Table Field Documentation Said Reality Is
enrollments ID id enrollment_id

products ID id product_id
