yii2-动态形式。我无法更新

Question

我想使用动态表单小部件 (wbraganca)。我使用 'doingItEasy' 频道和 github 的教程进行了尝试。我可以创建和删除，但我不能更新。:

控制器：

public function actionUpdate($id) {
    $model = $this->findModel($id);
    $modelsDentalist = $model->dentalists;

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        $oldIDs = ArrayHelper::map($modelsDentalist, 'id', 'id');
        $modelsDentalist = Model::createMultiple(Dentalist::classname(), $modelsDentalist);
        Model::loadMultiple($modelsDentalist, Yii::$app->request->post());
        $deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsDentalist, 'id', 'id')));

        $valid = $model->validate();
        $valid = Model::validateMultiple($modelsDentalist) && $valid;

        if ($valid) {
            $transaction = \Yii::$app->db->beginTransaction();
            try {
                if ($flag = $model->save(false)) {
                    if (!empty($deletedIDs)) {
                        CalItem::deleteAll(['id' => $deletedIDs]);
                    }
                    foreach ($modelsDentalist as $modelDentalist) {
                        $modelDentalist->denta_id = $model->denta_id;
                        if (!($flag = $modelDentalist->save(false))) {
                            $transaction->rollBack();
                            break;
                        }
                    }
                }
                if ($flag) {
                    $transaction->commit();
                    return $this->redirect(['index']);
                }
            } catch (Exception $e) {
                $transaction->rollBack();
            }
        }
    } else {
        return $this->render('update', [
                    'model' => $model,
                    'modelsDentalist' => (empty($modelsDentalist)) ? [new Dentalist] : $modelsDentalist
        ]);
    }
}

我无法更新。 Error:Getting 未知属性: app\models\Dentalist::id

Answer 1

我认为您可以在 Controller 中编辑以下行：

$oldIDs = ArrayHelper::map($modelsDentalist, 'denta_id', 'denta_id');
$modelsDentalist = Model::createMultiple(Dentalist::classname(), $modelsDentalist);
Model::loadMultiple($modelsDentalist, Yii::$app->request->post());
$deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsDentalist, 'denta_id', 'denta_id')));

并编辑 _form 中的行：

echo Html::activeHiddenInput($modelDentalist, "[{$i}]denta_id");
