# Asset Request Management Updates

## Summary of Changes

### 1. Custom Action Dialog Component
Created a new custom dialog component (`ActionDialog.tsx`) for approve/reject actions that:
- Provides a better user experience with custom styling
- Shows request details (ID and employee name) prominently
- Has built-in validation and error handling
- Displays character count for comments
- Uses backdrop blur effect for better focus
- Includes loading states during submission

### 2. Acknowledgement Status Added
Extended the asset request lifecycle to include an "acknowledged" status:

**Type Updates (`asset-request.ts`):**
- Added `'acknowledged'` to `RequestStatus` type
- Added new fields to `AssetRequest` interface:
  - `acknowledgedDate: string | null`
  - `acknowledgedBy: number | null`
  - `acknowledgementComments: string | null`
- Updated status transition rules: `assigned` → `acknowledged`
- Added label: "Acknowledged"
- Added color: purple theme for acknowledged status

**Status Flow:**
```
pending → approved → assigned → acknowledged
       ↘ rejected
```

### 3. Updated Components

**AssetRequestReview.tsx:**
- Replaced shadcn Dialog with custom ActionDialog component
- Simplified approve/reject handlers
- Removed local state management for comments (now handled by ActionDialog)
- Cleaner code with better separation of concerns

**MyAssetRequests.tsx:**
- Added acknowledgement status icon and color
- Added "Acknowledged" tab to display acknowledged requests
- Added acknowledgement information section showing:
  - Acknowledged date
  - Acknowledgement comments
- Updated tab grid from 5 to 6 columns

**assetRequestApi.ts:**
- Updated `createSafeAssetRequest` helper to include acknowledgement fields
- Ensures backward compatibility with API responses

### 4. Features

**Custom Dialog Benefits:**
- ✅ Better visual hierarchy
- ✅ Clearer action context
- ✅ Inline validation feedback
- ✅ Improved accessibility
- ✅ Consistent styling across approve/reject actions
- ✅ Backdrop click to close
- ✅ Escape key support (via onClose)

**Acknowledgement Status Benefits:**
- ✅ Employees can confirm receipt of assigned assets
- ✅ Complete audit trail of asset request lifecycle
- ✅ Optional comments for acknowledgement
- ✅ Clear visual distinction with purple badge
- ✅ Separate tab for tracking acknowledged requests

## Usage

### Approve/Reject Dialog
The custom dialog automatically handles:
- Comment validation (minimum 5 characters)
- Character count display
- Loading states
- Error messages
- Form submission

### Acknowledgement Flow
1. Admin assigns assets to approved request (status: `assigned`)
2. Employee receives notification
3. Employee acknowledges receipt (status: `acknowledged`)
4. Optional: Employee can add comments during acknowledgement

## API Integration Notes

The frontend now expects these additional fields in API responses:
```typescript
{
  acknowledgedDate: string | null,
  acknowledgedBy: number | null,
  acknowledgementComments: string | null
}
```

If the backend doesn't provide these fields yet, the frontend will safely default them to `null`.

## Next Steps

To fully implement acknowledgement functionality:
1. Add acknowledgement API endpoint (e.g., `PUT /api/AssetRequests/{id}/acknowledge`)
2. Add acknowledgement button in MyAssetRequests for assigned requests
3. Create acknowledgement dialog similar to approve/reject
4. Update backend to support acknowledgement status transition
5. Add notifications for acknowledgement events
