# Views Module Structure

This directory contains the refactored views from the original monolithic `views.py` file.

## File Organization

### `__init__.py`
Central import file that exports all views for easy access. This allows other modules to import views using:
```python
from mainapp.views import ObjItemListView, custom_logout
```

### `base.py`
Basic views and utilities:
- `ActionsPageView` - Displays the actions page
- `custom_logout()` - Custom logout function

### `objitem.py`
ObjItem CRUD operations and related views:
- `ObjItemListView` - List view with filtering and pagination
- `ObjItemFormView` - Base class for create/update operations
- `ObjItemCreateView` - Create new ObjItem
- `ObjItemUpdateView` - Update existing ObjItem
- `ObjItemDeleteView` - Delete ObjItem
- `ObjItemDetailView` - Read-only detail view
- `DeleteSelectedObjectsView` - Bulk delete operation

### `data_import.py`
Data import views for various formats:
- `AddSatellitesView` - Add satellites to database
- `AddTranspondersView` - Upload and parse transponder data from XML
- `LoadExcelDataView` - Load data from Excel files
- `LoadCsvDataView` - Load data from CSV files
- `UploadVchLoadView` - Upload VCH load data from HTML

- `ShowSelectedObjectsMapView` - Display selected objects on map

## Migration Notes

The original `views.py` has been renamed to `views_old.py` as a backup. All imports have been updated in:
- `dbapp/mainapp/urls.py`
- `dbapp/dbapp/urls.py`

## Benefits of This Structure

1. **Better Organization** - Related views are grouped together
2. **Easier Maintenance** - Smaller files are easier to navigate and modify
3. **Clear Responsibilities** - Each file has a specific purpose
4. **Improved Testability** - Easier to write focused unit tests
5. **Better Collaboration** - Multiple developers can work on different files without conflicts
