创建嵌套关系

它工作正常，我可以在嵌套关系中达到两个层次，但是当我尝试更新子模型的子模型的数据时，我陷入了困境。我不知道在方法之间传递记录ID的参数。

这就是我有3个相关模型和1个控制器的故事因此，控制器处理通过关联控制器关联了子模型和关联子模型的主模型，而子模型具有与此reference关联的子孙模型

主控制器

class WartaRutin extends Controller
{
    public $implement = ['Backend\Behaviors\ListController',
                         'Backend\Behaviors\FormController',
                         'Backend\Behaviors\RelationController']; 

    public $listConfig = 'config_list.yaml';
    public $formConfig = 'config_form.yaml';
    public $relationConfig = 'config_relation.yaml';

    public $requiredPermissions = ['mismaiti.mywarta.manage_plugins'];

    protected $kebumItemFormWidget;
    protected $updateItemForm;      

    public function __construct()
    {
        parent::__construct();
        BackendMenu::setContext('Mismaiti.MyWarta', 'main-menu-item', 'side-menu-rutin');

        $this->kebumItemFormWidget = $this->createKebumItemFormWidget();
        $this->updateItemForm = $this->updateItemFormWidget();
    }    

    public function onLoadCreateItemForm()
    {
        $this->vars['kebumItemFormWidget'] = $this->kebumItemFormWidget;    
        $this->vars['kebaktianId'] = post('manage_id');    
        return $this->makePartial('kebum_item_create_form');
    }

    public function onLoadUpdateItemForm()   
    {
        $this->vars['recordId'] = post('record_id'); //-- USE THIS record_id IN METHOD BELOW 
        $this->vars['updateItemForm'] = $this->updateItemForm;    
        return $this->makePartial('kebum_item_update_form'); 
    }

    protected function updateItemFormWidget()
    {
        //$recordId = post('record_id');   ---> USE record_id HERE 
        $config = $this->makeConfig('$/mismaiti/mywarta/models/kebumitem/kebum_item_fields.yaml');    
        $config->model = \Mismaiti\MyWarta\Models\KebumItem::find($recordId);    
        $widget = $this->makeWidget('Backend\Widgets\Form', $config);    
        $widget->bindToController();    
        return $widget;

    }

    public function onCreateItem()
    {
        $data = $this->kebumItemFormWidget->getSaveData();    
        $model = new \Mismaiti\MyWarta\Models\KebumItem;    
        $model->fill($data);    
        $model->save();    
        $kebaktian = $this->getKebumModel();    
        $kebaktian->kebumitems()->add($model, $this->kebumItemFormWidget->getSessionKey());

        return $this->refreshKebumItemList();
    }

    public function onUpdateItem()
    {
        $id = post('item_id');    
        $model = \Mismaiti\MyWarta\Models\KebumItem::find($id);            
        $data = $this->updateItemForm->getSaveData();       

        $model->fill($data);
        $model->save();     
        \Flash::success('Data has been updated!');
    }

    public function onDeleteItem()
    {
        $recordId = post('record_id');    
        $model = \Mismaiti\MyWarta\Models\KebumItem::find($recordId);

        $kebum = $this->getKebumModel();    
        $kebum->kebumitems()->remove($model, $this->kebumItemFormWidget->getSessionKey());

        return $this->refreshKebumItemList();
    }

    protected function createKebumItemFormWidget()
    {
        $config = $this->makeConfig('$/mismaiti/mywarta/models/kebumitem/kebum_item_fields.yaml');    
        $config->alias = 'kebumItemForm';    
        $config->arrayName = 'KebumItem';

        $config->model = new \Mismaiti\MyWarta\Models\KebumItem;   
        $widget = $this->makeWidget('Backend\Widgets\Form', $config);    
        $widget->bindToController();    
        return $widget;
    }      

    protected function getKebumModel()
    {
        $manageId = post('manage_id');    
        $kebaktian = $manageId
            ? \Mismaiti\MyWarta\Models\Kebaktian::find($manageId)
            : new \Mismaiti\MyWarta\Models\Kebaktian;    
        return $kebaktian;
    }

    protected function refreshKebumItemList()
    {
        $kebumItems = $this->getKebumModel()
            ->kebumitems()
            ->withDeferred($this->kebumItemFormWidget->getSessionKey())
            ->get();    
        $this->vars['kebumItems'] = $kebumItems;    
        return ['#itemList' => $this->makePartial('kebum_item_list')];
    }

}

如果我将数字放在数据库中的find(42)而不是id的{{1}}里面，我就在被卡住的那部分加注，它运行完美。.

$recordId

这是record_id的来源

$config->model = \Mismaiti\MyWarta\Models\KebumItem::find($recordId);

我希望有人可以帮助我。

Answer 1

我找到了解决方法。

protected $kebumItemFormWidget;
protected $updateKebumItemForm;

public function __construct()
{
    parent::__construct();
    BackendMenu::setContext('Mismaiti.MyWarta', 'main-menu-item', 'side-menu-rutin');

    $this->kebumItemFormWidget = $this->createKebumItemFormWidget();
    //$this->updateItemForm = $this->updateKebumItemFormWidget(); ---> i remove this from here
} 

public function onLoadUpdateKebumItemForm()   
{
    $id = post('record_id');
    Session::put('id',$id);
    $this->vars['id'] = $id;
    $this->vars['updateKebumItemForm'] = $this->updateKebumItemFormWidget(); // declare here instead 
        return $this->makePartial('kebum_item_update_form'); 
}

protected function updateKebumItemFormWidget()
{
    $id = Session::get('id');
    $config = $this->makeConfig('$/mismaiti/mywarta/models/kebumitem/kebum_item_fields.yaml'); 
    $config->model = \Mismaiti\MyWarta\Models\KebumItem::find($id);
    $widget = $this->makeWidget('Backend\Widgets\Form', $config);
    $widget->bindToController();
        return $widget;

}    

public function onUpdateKebumItem()
{
    $id = post('item_id');
    $this->updateKebumItemForm = $this->updateKebumItemFormWidget();
    $model = \Mismaiti\MyWarta\Models\KebumItem::find($id);        
    $data = $this->updateKebumItemForm->getSaveData();        
    $model->fill($data);
    $model->save(); 
    $kebaktian = $this->getKebumModel();
    $kebaktian->kebumitems()->add($model, $this->updateKebumItemForm->getSessionKey());
        \Flash::success('Data has been updated!'); 
        return $this->refreshKebumItemList();       
}

以嵌套关系传递recordId以更新表单
