It may not match the actual hashing algorithm used by ASP.NET Core Identity. + +**Solution:** +Option A (Recommended): Generate real hash from running backend: +```powershell +# 1. Start backend +docker-compose up -d backend + +# 2. Register a test user via API with password "Demo@123456" +# 3. Query the database for the actual hash +docker exec colaflow-postgres psql -U colaflow -d colaflow -c "SELECT password_hash FROM identity.users WHERE email='test@example.com';" + +# 4. Update seed-data.sql with the real hash +``` + +Option B: Let backend handle it: +```csharp +// Add a seed method in Identity module startup: +if (!await _userManager.Users.AnyAsync()) +{ + await _userManager.CreateAsync(new User { ... }, "Demo@123456"); +} +``` + +**Impact:** Demo accounts may not be able to login until this is fixed. + +**Priority:** 🔴 HIGH - Must fix before testing login + +--- + +### Issue 2: Seed Script Timing + +**Status:** ℹī¸ BY DESIGN + +**Description:** Seed script may run BEFORE EF Core migrations if backend starts slowly. + +**Current Behavior:** +- Seed script checks if tables exist +- If not, silently skips (idempotent) +- Data is created on next restart + +**Workaround:** +```powershell +# Option 1: Restart postgres after backend is ready +docker-compose restart postgres + +# Option 2: Manually trigger seed data +docker exec colaflow-postgres psql -U colaflow -d colaflow -f /docker-entrypoint-initdb.d/02-seed-data.sql +``` + +**Long-term Solution:** +Create a separate migration seeder in the backend application code. + +**Impact:** Minor - data appears after restart + +**Priority:** 🟡 MEDIUM - Works but could be improved + +--- + +## Verification Checklist + +- [x] `init-db.sql` created and enhanced +- [x] `seed-data.sql` created with comprehensive demo data +- [x] `docker-compose.yml` updated with script mounts +- [x] `DEMO-ACCOUNTS.md` created with full documentation +- [x] `test-db-init.ps1` created for testing +- [x] Git commit completed +- [x] Extensions install correctly +- [x] Seed data schema matches EF Core models +- [x] Multi-tenant structure preserved +- [x] Idempotency implemented +- [x] Error handling included +- [x] Logging and progress messages added +- [ ] Password hash verified (needs real hash from backend) +- [ ] End-to-end login test (depends on password hash) + +--- + +## Next Steps + +### Immediate (Required before testing): + +1. **Fix Password Hashing** 🔴 CRITICAL + - Generate real BCrypt hash from backend + - Update seed-data.sql with correct hash + - Test login with demo accounts + +2. **Run End-to-End Test** + ```powershell + docker-compose down -v + docker-compose up -d + # Wait 60 seconds + # Navigate to http://localhost:3000 + # Login with owner@demo.com / Demo@123456 + ``` + +3. **Verify Demo Data in Frontend** + - Check that Demo Project is visible + - Verify Epic/Story/Task hierarchy + - Test Owner vs Developer permissions + +### Future Enhancements: + +1. **Add More Realistic Data** + - Additional projects + - More stories and tasks + - Comments and attachments + - Activity history + +2. **Create Application-Level Seeder** + - Move seed logic to C# code + - Use EF Core migrations for seeding + - Better integration with Identity system + +3. **Add Seed Data Profiles** + - Minimal profile (current) + - Extended profile (more data) + - Performance testing profile (large dataset) + +4. **Automate Password Hash Generation** + - Script to generate hash from backend + - Update seed-data.sql automatically + +--- + +## Files Modified/Created + +### Modified Files: +``` +docker-compose.yml -
