类型错误 Yii2 框架

Question

yii\base\View::{closure}(): 参数 #2 ($model) 必须是 Libro 类型，app\models\Libro given

在 C:\xampp\htdocs\biblioteca\views\libro\index.php

'filterModel' => $searchModel,
'columns' => [
    ['class' => 'yii\grid\SerialColumn'],

    'id',
    'titulo',
    'imagen',
    [
        'class' => ActionColumn::className(),
     *   'urlCreator' => function ($action, Libro $model, $key, $index, $column) {*
            return Url::toRoute([$action, 'id' => $model->id]);
         }
    ],
],

]); ?>

Answer 1

将您的闭包更改为：

'urlCreator' => function ($action, Libro $model, $key, $index, $column) {*
    return Url::toRoute([$action, 'id' => $model->id]);
}

进入：

'urlCreator' => function ($action, \app\models\Libro $model, $key, $index, $column) {*
    return Url::toRoute([$action, 'id' => $model->id]);
}

In other words, use right class as type (\app\models\Libro instead of Libro).

Answer 2

在脚本开头包括以下行以及其他使用语句：

use app\models\Libro;
