Yii2如何在GridView中锚定关系的值

Question

I am beginner. I explain the topic:

there is this relationship in the Ticket model:

public function getTyp()
{
    return $this->hasOne(Typology::className(), [ 'id' =>'typ_id']);
}

and in the ticket table there is the typ_id column (it is in relationship with the id of the Typology table). In the view views/ticket/index.php there is GridView::widgetwith these columns:

  [
     'attribute' => 'typ_id',
     'value' => 'typ.typology' 
  ],

I want to anchor the value of the relationship. I have tried this:

  [
     'attribute' => 'typ_id',
     'value' => function ($model) {
               return Html::a (
              'typ.typology',
              '/typology/view?id='.$model->typ_id
               );
      }
  ]

but it doesn't work

someone can help me?

Answer 1

Html::a() interprets typ.typology as raw string. Use $model in value closure to get necessary property through relation.

Also instead of manually concatenate the url with its parameters, just pass them in array (see Url::to() to understand how link is constructed).

[
    'attribute' => 'typ_id',
    'value' => function ($model) {
        return Html::a($model->typ->typology, ['/typology/view', 'id' => $model->typ_id]);
    },
],
