defmodule MvWeb.GlobalSettingsLive do
@moduledoc """
LiveView for managing global application settings (Vereinsdaten).
## Features
- Edit the association/club name
- Manage custom fields
- Real-time form validation
- Success/error feedback
- CSV member import (admin only)
## Settings
- `club_name` - The name of the association/club (required)
## Events
- `validate` - Real-time form validation
- `save` - Save settings changes
- `start_import` - Start CSV member import (admin only)
## CSV Import
The CSV import feature allows administrators to upload CSV files and import members.
### File Upload
Files are uploaded automatically when selected (`auto_upload: true`). No manual
upload trigger is required.
### Rate Limiting
Currently, there is no rate limiting for CSV imports. Administrators can start
multiple imports in quick succession. This is intentional for bulk data migration
scenarios, but should be monitored in production.
### Limits
- Maximum file size: 10 MB
- Maximum rows: 1,000 rows (excluding header)
- Processing: chunks of 200 rows
- Errors: capped at 50 per import
## Note
Settings is a singleton resource - there is only one settings record.
The club_name can also be set via the `ASSOCIATION_NAME` environment variable.
