我在FilamentPHP（v3）项目中使用spatie/laravel-model-states。为了让状态在表单中正确显示，我必须在state类中实现Wireable，看起来像这样：

abstract class InventoryItemState extends State implements Wireable {
    public static function config(): StateConfig
    {
        return parent::config()
            ->default(Received::class)
            ->allowTransition(Received::class, Sanitized::class)
            ->allowTransition(Sanitized::class, Sold::class)
            ->allowTransition(Sold::class, Sanitized::class);
    }

    public function toLivewire() {
        return [
            'name' => $this->getValue()
        ];
    }

    public static function fromLivewire($value) {
        return new static($value);
    }
}

字符串
示例状态如下所示：

class Received extends InventoryItemState {
    public static $name = 'received';
}

在表单中，我显示了这个特定项目可以转换到的可用状态：

namespace App\Filament\Resources;
class InventoryItemResource extends Resource
{
    protected static ?string $model = InventoryItem::class;

    protected static ?string $navigationIcon = 'heroicon-o-rectangle-stack';

    public static function form(Form $form): Form
    {
        $potential_states = $form->getRecord()->state->transitionableStates();
        // Some other stuff not relevant
        $formSchema = [
            // other form options
        ];
        if (!empty($potential_states)) {
            $options = collect($potential_states)
                ->keyBy(fn ($item) => $item)
                ->toArray();
            $formSchema[] = Forms\Components\Radio::make('state')
                ->options($options);
        }
        $schema[] =
            Section::make()
                ->compact()
                ->columns(2)
                ->schema($formSchema);

        return $form
            ->schema($schema);
    }

    // Other stuff removed
}

型
这可以将可转换状态显示为单选按钮：

然而，在保存时，我得到了这个错误：
foreach（）参数必须为数组类型|对象，给定的字符串
来自Livewire\Features\SupportWireables\WireableSynth.php：

function hydrate($value, $meta, $hydrateChild) {
    foreach ($value as $key => $child) {
        $value[$key] = $hydrateChild($key, $child);
    }

    return $meta['class']::fromLivewire($value);
}

型
很容易看出原始值是一个数组：

并且表单将其设置为的值不是：

所以WireableSynth::hydrate显然期望一个数组，而当值被更改并提交表单时，它并没有得到这个数组。
