Extending Relation Managers

Relation manager extensions allow modifying the form and table of any relation manager in the Lunar admin panel. Create a class that extends RelationManagerExtension and register it with the LunarPanel facade.

Example

The following example extends the CustomerGroupPricingRelationManager to add a custom column to the form and table:

use Filament\Forms\Components\TextInput;
use Filament\Forms\Form;
use Filament\Tables\Columns\TextColumn;
use Filament\Tables\Table;
use Lunar\Admin\Support\Extending\RelationManagerExtension;

class MyCustomerGroupPricingExtension extends RelationManagerExtension
{
    public function extendForm(Form $form): Form
    {
        return $form->schema([
            ...$form->getComponents(withHidden: true),
            TextInput::make('custom_column'),
        ]);
    }

    public function extendTable(Table $table): Table
    {
        return $table->columns([
            ...$table->getColumns(),
            TextColumn::make('product_code'),
        ]);
    }
}

// Typically placed in a service provider...
LunarPanel::extensions([
    \Lunar\Admin\Filament\Resources\ProductResource\RelationManagers\CustomerGroupPricingRelationManager::class => MyCustomerGroupPricingExtension::class,
]);
