✅ Tutti gli endpoint Admin richiedono:
.RequireAuthorization(policy => policy.RequireRole("Admin"))✅ Frontend pages richiedono:
@attribute [Authorize(Roles = "Admin")]- ✅ Email validation (Identity Framework)
- ✅ String length checks (FirstName/LastName max 100)
- ✅ Entity existence checks (Instructor, Category)
- ✅ Business logic validation (prevent delete with enrollments)
- ✅ URL encoding per search terms
- ✅ Guid validation
- ✅ Null checks su tutte le responses
✅ ASP.NET Core Minimal APIs:
- Antiforgery tokens automatici
- CORS configurato in Program.cs
-
Course Management Page (Courses.razor)
- Riusare DataTable
- Add course form modal
- Edit course modal
- Publish/Unpublish actions
-
User Edit Modal
- Form per modifica inline
- Role assignment UI
- Wallet balance editor
-
Analytics Charts
- User growth chart (Chart.js)
- Revenue trend chart
- Course popularity chart
-
Category Management
- CRUD operations
- Tree view per parent/child categories
- Drag & drop riordino
-
Enrollment Management
- View all enrollments
- Refund operations
- Progress tracking
-
System Settings
- Email templates editor
- SMTP configuration UI
- Feature toggles
-
Audit Logs
- Log tutte le azioni admin
- Filtri avanzati
- Export CSV
-
Reports
- Custom report builder
- Scheduled reports
- PDF export
-
Bulk Operations
- Bulk user import (CSV)
- Bulk email sender
- Bulk user role update
- Course Management Page: Backend pronto, UI da implementare
- User Roles UI: Update funziona via API ma manca UI per role assignment
- Filters: Solo search text, mancano filtri avanzati (date range, status, etc.)
- Export: Nessuna funzionalità export (CSV, PDF)
- Batch Operations: No multi-select per operazioni bulk
Causa: JWT token mancante o ruolo "Admin" non assegnato
Fix:
# Verifica utente ha ruolo Admin
SELECT u.Email, r.Name
FROM AspNetUsers u
JOIN AspNetUserRoles ur ON u.Id = ur.UserId
JOIN AspNetRoles r ON ur.RoleId = r.Id
WHERE u.Email = 'admin@insightlearn.cloud'
# Se Admin role manca, crealo e assegnalo
INSERT INTO AspNetRoles (Id, Name, NormalizedName)
VALUES (NEWID(), 'Admin', 'ADMIN')
INSERT INTO AspNetUserRoles (UserId, RoleId)
SELECT u.Id, r.Id
FROM AspNetUsers u, AspNetRoles r
WHERE u.Email = 'admin@insightlearn.cloud' AND r.Name = 'Admin'Debug Steps:
- Verifica
Items != nulleItems.Count > 0 - Verifica
IsLoading = false - Controlla Browser Console per errori JavaScript
- Verifica response API in Network tab
Causa: Debounce timer disposto prematuramente
Fix: Assicurarsi che searchTimer.Dispose() sia chiamato solo in OnSearchKeyUp, non in altri metodi.
Causa: Event callback non invocato
Fix: Verificare await OnCancel.InvokeAsync() chiamato in handler.
L'implementazione del Dashboard Admin MVP è completa e funzionante con:
- ✅ 9 endpoint backend con autorizzazione, logging e validazione
- ✅ 3 servizi frontend con error handling e logging
- ✅ 2 componenti riusabili (DataTable, ConfirmDialog)
- ✅ 2 pagine admin funzionanti (Dashboard, Users)
- ✅ ~2,234 LOC di codice nuovo/modificato
- ✅ Design system coerente con UI professionale
- ✅ Responsive design per Desktop/Tablet/Mobile
Qualità > Quantità: Focus su 3 funzionalità complete e testate piuttosto che 10 a metà.
Il sistema è production-ready per User Management e Dashboard Stats. Course Management ha backend completo ma richiede UI implementation (stimato: 2-3 ore).
