查看操作

简介

Filament 包含一个可以查看 Eloquent 记录的操作(Action)。点击触发按钮时，会打开一个带有信息的模态框。Filament 使用表单字段来构建这些信息。所有表单字段都是禁用状态，因此用户无法编辑。你可以像这样使用它：

use Filament\Actions\ViewAction;
use Filament\Forms\Components\TextInput;

ViewAction::make()
    ->schema([
        TextInput::make('title')
            ->required()
            ->maxLength(255),
        // ...
    ])

自定义填充表单前的数据

你可能希望在记录填入到表单之前修改数据。为此，你可以使用 mutateRecordDataUsing() 方法修改 $data 数组，并且返回其填充到表单前修改的版本：

use Filament\Actions\ViewAction;

ViewAction::make()
    ->mutateRecordDataUsing(function (array $data): array {
        $data['user_id'] = auth()->id();

        return $data;
    })

除了 $data 之外，mutateRecordDataUsing() 函数还可以将各种 utility 作为参数注入其中。
