Yii2 GridView属性格式由不同的属性值定义

Question

I would like to define the format of an attribute in GridView based on a db field value. I was trying for example like this:

'format' => function ($model) {return $model->format;}, // it should return 'boolean'

but I have tried many other ways also, but it's not working. I'm getting:

PHP Notice – yii\base\ErrorException

Trying to get property of non-object

If I'm simply returning format as an attribute, it's working without any issues. It seems that it's not accepting it in the format section. Is it possible anyways what I'm trying to achieve? Can you please point me to the right direction?

Answer 1

Closures for format are not supported. You may use raw format and do formatting in Closure for value:

[
    'attribute' => 'name',
    'type' => 'raw',
    'value' => function ($model) {
        $format = 'as' . ucfirst($model->format);
        return Yii::$app->formatter->$format($model->name);
    },
],

Answer 2

Refer Yii2 Formatter

Example:

<?= GridView::widget([
     'id' => 'grid-list',
     'dataProvider' => $dataProvider,
     [
         'attribute' => 'format_date',
          // 'format' => 'raw',
         'value' => function ($model) {
              // Here use \Yii::$app->formatter->asDate();
              // Ex: return \Yii::$app->formatter->asDate($model->format_date);
              return \Yii::$app->formatter->asDate($model->format_date);
         },
     ],
]) ?>
