Yii2 Php-Call 到数组上的成员函数 getAttributeLabel()

Question

我有3个观点。创建和更新视图是相同的。在 _form.php 查看文件中。我有这个：

 <?php
  use yii\bootstrap\ActiveForm;
 ?>

 <?php $form = ActiveForm::begin(); ?>
        <?= $form->field($model, 'name') ?>
        <?= $form->field($model, 'adr_country_id') ->dropDownList($cities) ?>
<?php ActiveForm::end()?>

在创建和更新视图中：

<?= $this->render('_form', ['model' => $model, cities' => $cities ]); ?>

。我可以创建新记录但无法更新它。我得到了标题中的错误。这是我的更新控制器。这可能是什么问题？提前致谢

public function actionUpdate($id) {

$model = ArrayHelper::map(AdrCountry::find()->all(),'id','name');
$cities = AdrCity::findOne($id);

if ($cities->load(Yii::$app->request->post()) && $cities->validate())
{
    $cities->save();
    Yii::$app->session->setFlash('success', ' updated');
    return $this->redirect(['index']);
}
return $this->render('update',[
    'cities' => $cities,
    'model' => $model
]); }

更新控制器的操作

public function actionUpdate($id) {

$cities = ArrayHelper::map(AdrCountry::find()->all(),'id','name');
$model = AdrCity::findOne($id);

if ($model->load(Yii::$app->request->post()) && $model->validate())
{
    $model->save();
    Yii::$app->session->setFlash('success', ' updated');
    return $this->redirect(['index']);
}
return $this->render('update',[
    'cities' => $cities,
    'model' => $model
]); }
