## 📌 Overview
|
|
|
|
### Purpose
|
|
Implement a comprehensive admin module that allows the application owner (Lasse) to manage users, generate story content, and access progress reports. This is **mission-critical** for the application as it enforces the requirement that **all visitors must sign up before accessing any learning content**.
|
|
|
|
### User Stories
|
|
- **As an admin**, I want to generate stories for levels so that users have content to learn from
|
|
- **As an admin**, I want to view user lists and their progress so that I can monitor application usage
|
|
- **As an admin**, I want to view progress reports so that I can understand how users are engaging with the platform
|
|
- **As a visitor**, I must sign up and login before I can access any learning content (stories, lessons, quizzes)
|
|
|
|
### Acceptance Criteria
|
|
- [x] All learning content endpoints require authentication (no public access)
|
|
- [x] User registration is mandatory before accessing any content
|
|
- [x] Admin role exists and is assigned to specific users only
|
|
- [x] Admin can access story generation UI/API
|
|
- [x] Admin can view list of all users
|
|
- [x] Admin can view individual user progress (lessons completed, stories unlocked)
|
|
- [x] Admin can generate reports on user activity
|
|
- [x] Admin endpoints are protected and only accessible to admin users

## 🏗️ Technical Design
|
|
|
|
### Components Involved
|
|
|
|
#### Backend (GermanApp)
|
|
- **Controllers**: AdminController (new), UserController (new), ReportController (new)
|
|
- **Services**: AdminService (new), UserReportService (new)
|
|
- **Entities**: User (existing), StorySegment (existing), StoryProgress (existing), UserProgress (existing)
|
|
- **Repositories**: IUserRepository (existing), IStoryProgressRepository (existing), IUserProgressRepository (existing)
|
|
- **DTOs**: UserDto, UserListDto, UserProgressDto, ProgressReportDto, StoryGenerationRequestDto (existing)
|
|
- **Middleware**: Role-based authorization (existing JWT infrastructure)
|
|
|
|
#### Frontend (german-app-frontend)
|
|
- **Pages**: AdminDashboard (new), AdminUsers (new), AdminReports (new), AdminStoryGenerator (new)
|
|
- **Components**: UserList (new), UserCard (new), ProgressChart (new), StoryGenerationForm (new)
|
|
- **Services**: adminApi (new), authService (existing)
|
|
- **Types**: User, UserProgress, ProgressReport (new)
|
|
- **Routing**: Protected admin routes with role check
|
|
|
|
#### Infrastructure
|
|
- **Database**: No new tables needed (uses existing Users, StoryProgress, UserProgress, StorySegments)
|
|
- **Configuration**: Admin role configuration in JWT claims
|
|
|
|
### Data Flow
|
|
|
|
#### User Authentication Flow (Mandatory)
|
|
```
|
|
1. Visitor arrives at / (home page)
|
|
2. Frontend checks localStorage for JWT token
|
|
3. If no token → redirect to /login
|
|
4. User enters credentials → POST /api/auth/login
|
|
5. Backend validates → returns JWT token
|
|
6. Frontend stores token → redirects to /learn or /story/1
|
|
7. All subsequent requests include Authorization: Bearer <token>
|
|
8. Backend middleware validates token → allows access to protected endpoints
|
|
```
|
|
|
|
#### Story Generation Flow (Admin Only)
|
|
```
|
|
1. Admin navigates to /admin/stories
|
|
2. Frontend verifies user has admin role (from JWT claims)
|
|
3. Admin selects level (1-5) and enters theme
|
|
4. Frontend POST /api/admin/stories/generate with {levelId, theme, segmentCount}
|
|
5. Backend verifies admin role
|
|
6. Backend extracts vocabulary from level's lessons
|
|
7. Backend calls Mistral AI with CEFR-specific prompt
|
|
8. Backend splits story into segments
|
|
9. Backend saves segments to database
|
|
10. Backend returns success with generated segments
|
|
11. Frontend shows success message
|
|
```
|
|
|
|
#### User Management Flow (Admin Only)
|
|
```
|
|
1. Admin navigates to /admin/users
|
|
2. Frontend verifies admin role
|
|
3. Frontend GET /api/admin/users
|
|
4. Backend verifies admin role
|
|
5. Backend fetches all users from database
|
|
6. Backend returns user list with basic info
|
|
7. Frontend displays user table with filters
|
|
8. Admin clicks on user → GET /api/admin/users/{id}/progress
|
|
9. Backend returns detailed progress for that user
|
|
10. Frontend displays user progress dashboard
|
|
```
|
|
|
|
#### Report Generation Flow (Admin Only)
|
|
```
|
|
1. Admin navigates to /admin/reports
|
|
2. Frontend verifies admin role
|
|
3. Admin selects report type (user activity, progress, etc.)
|
|
4. Frontend GET /api/admin/reports/{type}?startDate=...&endDate=...
|
|
5. Backend verifies admin role
|
|
6. Backend aggregates data based on report type
|
|
7. Backend returns report data
|
|
8. Frontend renders report with charts/tables
|
|
```
|
|
|
|
### API Endpoints

|
|
|
|
### Database Schema
|
|
No new tables required. Uses existing:
|
|
- `Users` - User accounts

## 📝 Notes & Decisions
|
|
|
|
### Design Decisions
|
|
|
|
1. **Single Admin User**: Initially, there will be only one admin user (Lasse). Admin role will not be assignable via API to prevent privilege escalation attacks. Admin role will be set directly in the database.
|
|
|
|
2. **Mandatory Authentication**: ALL learning content requires authentication. No exceptions. This is a core business requirement. Users cannot access stories, lessons, or quizzes without first registering and logging in.
|
|
|
|
3. **Role-Based Authorization**: Using ASP.NET Core's built-in `[Authorize(Roles = "Admin")]` attribute for admin-only endpoints. Regular authenticated users can access learning content, but only admin users can access admin endpoints.
|
|
|
|
4. **Progress Tracking**: User progress (lesson completion, story unlock/completion) is tracked per user and is essential for the story unlocking feature to work correctly.
|
|
|
|
### Gotchas & Considerations
|
|
|
|
- **CORS with Credentials**: When using JWT tokens with credentials, CORS configuration must explicitly list allowed origins (cannot use wildcard `AllowAnyOrigin()` with `AllowCredentials()`).
|
|
- **Token Storage**: Frontend stores JWT tokens in localStorage. Consider HttpOnly cookies for enhanced security (future enhancement).
|
|
- **Admin Bootstrapping**: First admin user must be created via direct database manipulation or a special bootstrap endpoint (which should be removed after first use).
|
|
- **Role Migration**: Existing User table may need a `Role` column added via migration.
|
|
|
|
### Future Enhancements
|
|
|
|
- [ ] Admin user management (add/remove admins via UI)
|
|
- [ ] Admin action audit logging
|
|
- [ ] User export/import functionality
|
|
- [ ] Bulk story generation
|
|
- [ ] Scheduled report generation (email)
|
|
- [ ] User activity notifications

**Last Updated**: June 14, 2025
|
|
|
|
**Note**: Phase 4 (Admin Module) authentication enforcement was completed on June 14, 2025. All learning content endpoints now require JWT authentication. The LessonsEndpoints.cs minimal API endpoints were updated to include `.RequireAuthorization()` on all GET endpoints, ensuring that all lesson-related API calls require authentication. |
