在View Yii 2中显示相关数据
我是Yii 2的新手，我正在为我学校的图书馆创建一个清单系统，但是我遇到了问题。
首先，我有一个这样的关系：
我想显示他认为的一本书的所有adq（每本书唯一的编号-这样我们就不必为每本副本都再次捕获该本书）与书adq相关的{1}}显然位于底部。

$this->params['breadcrumbs'][] = ['label' => 'Libros', 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;

我如何完成此任务？

[
'attribute' => 'adq_libro_id',
'value' => implode(', ', \yii\helpers\ArrayHelper::map($model->Adqs, 'id',
function ( $model )
{
return $model['adq'];
}
)),
'format' => 'raw'
],
尝试这样。检查属性的正确名称

在模型Libros.php中，您具有此功能。
public function getAdqs()
{
return $this->hasMany(Adq::className(), ['adq_libro_id' => 'lib_id']);
}
这意味着您可以像这样访问Libros的关系：
// where $model is an instance of Libros
$model->adqs->property_name
或作为功能
$model->getAdqs();
