删除操作 - Actions

简介

Filament 包含一个能够删除 Eloquent 记录的操作。点击触发按钮时，会打开一个请求用户确认模态框。你可以像这样使用它：

use Filament\Actions\DeleteAction;

DeleteAction::make()

或者，如果你想添加表格批量操作按钮，以便用户可以选择删除哪些行，请使用 Filament\Actions\DeleteBulkAction：

use Filament\Actions\DeleteBulkAction;
use Filament\Tables\Table;

public function table(Table $table): Table
{
    return $table
        ->toolbarActions([
            DeleteBulkAction::make(),
        ]);
}

删除后重定向

使用 successRedirectUrl() 方法你可以设置删除记录后的重定向网址：

use Filament\Actions\DeleteAction;

DeleteAction::make()
    ->successRedirectUrl(route('posts.list'))

除了 $record 之外，successRedirectUrl() 函数可以注入各种 utility 作为参数。

自定义删除通知

记录成功删除后，会派送通知给用户，说明操作成功：

要自定义通知标题，请使用 successNotificationTitle() 方法：

use Filament\Actions\DeleteAction;

DeleteAction::make()
    ->successNotificationTitle('User deleted')

除了允许静态值之外，successNotificationTitle() 方法也可以接受函数动态计算其值。你可以将各种 utility 作为参数注入到函数中。

    ->successNotification(
       Notification::make()
            ->success()
            ->title('User deleted')
            ->body('The user has been deleted successfully.'),
    )

生命周期钩子

你可以使用 before() 和 after() 方法，在记录删除之前及之后执行代码：

use Filament\Actions\DeleteAction;

DeleteAction::make()
    ->before(function () {
        // ...
    })
    ->after(function () {
        // ...

改进批量删除操作的性能

默认情况下，DeleteBulkAction 将会将所有 Eloquent 记录加载到内存中，然后循环并逐一删除它们。

如果删除的记录数量太大，你可能会希望使用 chunkSelectedRecords() 方法，一次或许较小的数据量。这能够减少应用的内存使用：

use Filament\Actions\DeleteBulkAction;

DeleteBulkAction::make()
    ->chunkSelectedRecords(250)

Filament 在删除记录前将它们加载入内存出于两个原因：

允许在删除之前使用模型策略对集合中的单个记录进行授权(比如，使用 authorizeIndividualRecords('delete') 策略)。
确保在删除记录时运行模型事件，例如模型观察者中的 deleting 和 deleted 事件。

如果你不需要单独的记录策略授权和模型事件，则可以使用 fetchSelectedRecords(false) 方法，该方法在删除记录之前不会将其提取到内存中，而是在单次查询中删除它们：

use Filament\Actions\DeleteBulkAction;

DeleteBulkAction::make()
    ->fetchSelectedRecords(false)
