-- Students can view own completions
CREATE POLICY "Students can view own completions"
ON lesson_completions FOR SELECT
TO authenticated
USING (auth.uid() = user_id);

-- Teachers and admins view all
CREATE POLICY "Teachers and admins view all completions"
ON lesson_completions FOR SELECT

Bug Fixes & Improvements

Critical Fixes

1. Course Detail Page 404 Error

Date: January 30, 2026 File: app/dashboard/student/courses/[courseId]/page.tsx

Problem:

// BEFORE (broken)
const { data: course } = await supabase
  .from('courses')
  .select(`author:profiles!courses_author_id_fkey(...)`)

Root Cause: Foreign key referenced wrong table (profiles instead of auth.users)

Solution:

// AFTER (working)
const { data: course } = await supabase
  .from('courses')
  .select('course_id, title, description, thumbnail_url, author_id')

// Get profile separately
const { data: authorProfile } = await supabase
  .from('profiles')
  .select('full_name, avatar_url')
  .eq('id', course.author_id)

Impact: Course detail page now loads correctly

2. Lesson Completion RLS Block

Date: January 30, 2026

Problem: Students couldn't INSERT into lesson_completions

Solution: Created proper RLS policies (see Phase 8)

Impact: Students can now track progress

Minor Improvements

  1. Login Redirect

    • Issue: Redirects to /protected instead of dashboard
    • Status: Documented, low priority
    • Impact: Minimal (works, just not optimal)
  2. Signout Route Missing

    • Issue: /auth/signout returns 404
    • Status: Documented
    • Impact: Low (can clear session manually)
  3. Duplicate Course Data

    • Issue: Seed script ran twice
    • Status: Known artifact
    • Impact: None (test data only)

Testing & Quality Assurance

    • Priority: Low
  3. Duplicate Test Data

    • Seed script ran multiple times
    • Impact: None (test data only)
    • Priority: N/A

Future Enhancements
