This ActiveAdmin configuration manages the Currency model in your application, allowing administrators to view and manage currency records with specific constraints.

File: currency.rb

1. Actions Configuration

• actions :all, except: :destroy
  • All CRUD actions are enabled except for destroy. This prevents the deletion of currency records, which might be critical to your system's operations.

2. Permitted Parameters

• permit_params :active
  • Only the active attribute can be modified through the admin interface, controlling whether a currency is active or inactive.

3. Sorting Configuration

• config.sort_order = 'entity_asc'
  • Records are sorted by the entity attribute in ascending order by default.

4. Scopes Configuration

• Custom Scopes
  • scope('Active', default: true) { |scope| scope.where(active: true) }
    • Displays only active currencies by default.
  • scope('Inactive') { |scope| scope.where(active: false) }
    • Allows filtering to show only inactive currencies.

5. Menu Configuration

• menu parent: 'Configuration', label: 'Currencies'
  • The Currency resource is placed under the "Configuration" menu with the label "Currencies."

6. Commented Permit Parameters

• permit_params
  • The commented-out section suggests additional attributes (entity, currency, alphabetic_code, numeric_code, minor_unit) that could be permitted if needed. These could be uncommented if you later decide to allow modifications to these fields.

Summary:

• Currency Management: This ActiveAdmin setup is focused on managing the active status of currencies, ensuring that only the active field can be modified.
• Scoped Views: The default scope is set to display only active currencies, with an option to view inactive ones.
• Controlled Editing: The configuration allows minimal editing, preventing accidental changes to critical currency attributes like codes or names, unless explicitly enabled.
