✅ Waitlist Admin Management - Implementation Checklist

Issue: Allow admins to manage waitlist entries

Requirements

  • Update endpoint
  • Delete endpoint
  • Soft delete support
  • Audit logs

Acceptance Criteria

  • Only admins can modify data
  • Changes tracked

Implementation Details

1. Database Layer ✅

Entity Updates

  • Added deleted_at column to Waitlist entity
  • Imported DeleteDateColumn from TypeORM
  • File: src/modules/waitlist/entities/waitlist.entity.ts

Migration

  • Created migration: 1740437000000-AddSoftDeleteToWaitlist.ts
  • Adds deleted_at TIMESTAMP NULL column
  • Includes rollback (down) method
  • File: src/database/migrations/1740437000000-AddSoftDeleteToWaitlist.ts

2. DTOs ✅

  • Created UpdateWaitlistDto
  • Validation: at least one field required
  • Email format validation
  • Telegram username format validation (@username, 5-32 chars)
  • File: src/modules/waitlist/dto/update-waitlist.dto.ts

3. Service Layer ✅

Methods Added to WaitlistService

  • update(id, dto) - Update entry with duplicate checking
  • softDelete(id) - Soft delete using TypeORM
  • hardDelete(id) - Permanent deletion
  • Imported UpdateWaitlistDto
  • Error handling for not found entries
  • Conflict handling for duplicates
  • File: src/modules/waitlist/waitlist.service.ts

4. Controller Layer ✅

Endpoints Added to WaitlistAdminController

  • PATCH /admin/waitlist/:id - Update endpoint
  • DELETE /admin/waitlist/:id - Soft delete endpoint
  • DELETE /admin/waitlist/:id/permanent - Hard delete endpoint

Security & Features

  • JWT authentication guard
  • Admin role guard
  • Rate limiting (30/min for update/soft delete, 10/min for hard delete)
  • Request object injection for audit logging
  • Swagger/OpenAPI documentation
  • Proper HTTP status codes (200, 204, 400, 401, 403, 409)

Audit Logging Integration

  • Injected AdminLogsService
  • Log update actions with changes
  • Log soft delete actions
  • Log hard delete actions
  • Include admin ID, target ID, IP, user agent
  • File: src/modules/waitlist/waitlist-admin.controller.ts

5. Module Configuration ✅

  • Imported AdminLogsModule into WaitlistModule
  • AdminLogsService available for dependency injection
  • File: src/modules/waitlist/waitlist.module.ts

6. Testing ✅

Controller Tests

  • Test update endpoint
  • Test soft delete endpoint
  • Test hard delete endpoint
  • Verify audit logging calls
  • File: src/modules/waitlist/waitlist-admin-update-delete.controller.spec.ts

Service Tests

  • Test update method - success case
  • Test update method - not found error
  • Test update method - duplicate conflict
  • Test soft delete - success
  • Test soft delete - not found error
  • Test hard delete - success
  • Test hard delete - not found error
  • File: src/modules/waitlist/waitlist-update-delete.service.spec.ts

7. Documentation ✅

  • Feature documentation: backend/WAITLIST_ADMIN_MANAGEMENT.md
  • Implementation summary: WAITLIST_ADMIN_IMPLEMENTATION.md
  • API quick reference: backend/WAITLIST_ADMIN_API.md
  • Usage examples (cURL, JavaScript/TypeScript)
  • Security documentation
  • Testing instructions

  -H "Content-Type: application/json" \
  -d '{"email_address": "test@example.com"}'

# Test soft delete
curl -X DELETE "http://localhost:3000/admin/waitlist/1" \
  -H "Authorization: Bearer $TOKEN"

# Check audit logs
