## Database Schema
|
|
|
|
### Settings Table (New)
|
|
Required columns for NocoDB Settings table:
|
|
- `key` (Single Line Text): Setting identifier
|
|
- `title` (Single Line Text): Display name
|
|
- `Geo-Location` (Text): Format "latitude;longitude"
|
|
- `latitude` (Decimal): Precision 10, Scale 8
|
|
- `longitude` (Decimal): Precision 11, Scale 8
|
|
- `zoom` (Number): Map zoom level
|
|
- `category` (Single Select): "system_setting"
|
|
- `updated_by` (Single Line Text): Last updater email
|
|
- `updated_at` (DateTime): Last update time
|
|
|
|
### Login Table (Existing - Updated)
|
|
Ensure the existing login table has:
|
|
- `Admin` (Checkbox): Admin privileges column
|
|
|
|
## Features Implemented
|
|
|
|
### Admin Authentication
|
|
- Admin status determined by `Admin` checkbox in login table
|
|
- Session-based authentication with admin flag
|
|
- Protected admin routes with `requireAdmin` middleware
|
|
- Automatic redirect to login for non-admin users
|
|
|
|
### Start Location Management
|
|
- Interactive map interface for setting coordinates
|
|
- Manual coordinate input with validation
|
|
- "Use Current Map View" button for easy positioning
|
|
- Real-time map updates when coordinates change
|
|
- Draggable marker for precise positioning
|
|
|
|
### Data Persistence
|
|
- Start location stored in NocoDB Settings table
|
|
- Same geographic data format as main locations table
|
|
- Automatic creation/update of settings records
|
|
- Audit trail with `updated_by` and `updated_at` fields
|
|
|
|
### Cascading Fallback System
|
|
1. **Database** (highest priority): Admin-configured location
|
|
2. **Environment** (medium priority): .env file defaults
|
|
3. **Hardcoded** (lowest priority): Edmonton coordinates
|
|
|
|
### User Experience
|
|
- All users automatically see admin-configured start location
|
|
- Admin users see ⚙️ Admin button in header
|
|
- Seamless navigation between main map and admin panel
|
|
- Real-time validation and feedback
|
|
|
|
## API Endpoints
|
|
|
|
### Admin Endpoints (require admin auth)
|
|
- `GET /admin.html` - Serve admin panel page
|
|
- `GET /api/admin/start-location` - Get start location with source info
|
|
- `POST /api/admin/start-location` - Save new start location
|
|
|
|
### Public Endpoints
|
|
- `GET /api/config/start-location` - Get start location for all users
|
|
|
|
## Security Features
|
|
- Admin-only access to configuration endpoints
|
|
- Input validation for coordinates and zoom levels
|
|
- Session-based authentication
|
|
- CSRF protection through proper HTTP methods
|
|
- HTML escaping to prevent XSS
|
|
|
|
## Next Steps
|
|
|
|
1. **Setup Database Tables**:
|
|
- Create the Settings table in NocoDB with required columns
|
|
- Ensure Login table has Admin checkbox column
|
|
|
|
2. **Configure Environment**:
|
|
- Add `NOCODB_SETTINGS_SHEET` URL to .env file
|
|
|
|
3. **Test Admin Functionality**:
|
|
- Login with admin user
|
|
- Access `/admin.html`
|
|
- Set start location and verify it appears for all users
|
|
|
|
4. **Future Enhancements** (ready for implementation):
|
|
- Additional admin settings (map themes, marker styles, etc.)
|
|
- Bulk location management
|
|
- User management interface
|
|
- System monitoring dashboard
|
|
|
|
## Benefits Achieved
|
|
|
|
✅ **Centralized Control**: Admins can change default map view for all users
|
|
✅ **Persistent Storage**: Settings survive server restarts and deployments
|
|
✅ **User-Friendly Interface**: Interactive map for easy configuration
|
|
✅ **Data Consistency**: Uses same format as main location data
|
|
✅ **Security**: Proper authentication and authorization
|
|
✅ **Scalability**: Easy to extend with additional admin features
|
|
✅ **Reliability**: Multiple fallback options ensure map always loads
|
|
|
|
The implementation provides a robust foundation for administrative control while maintaining the existing user experience and security standards.
