yii2 gridview Object of class Closure could not be converted to int

Yii 2.0 General Discussions

was going to call the data from model in gridview. I installed advanced grid view via composer and I am using \yiister\grid\widgets\ProgressColumn. but the prolem ProgressColumn widget is not taking

‘value’=>function($model){

   $model->paxtashart;


 },

as int value, it gives me error: Object of class Closure could not be converted to int

is there any possiblity that I can convert it to int or any other alternative?

here let me present you my entire code:

[

'class' => \yiister\grid\widgets\ProgressColumn::className(),


'attribute' => 'paxta_given',


'size' => \yiister\grid\widgets\ProgressColumn::SIZE_LARGE,


'isAnimated' => true,


 'value'=>function($model){


   $model->paxtashart;


 },





// 'maxValue'=> $fermercha->paxtashart,


// 'minValue'=> $fermercha->paxta_given,


'progressBarClass' => function ($model, $column) {


    return $model->{$column->attribute} > 60


        ? \yiister\grid\widgets\ProgressColumn::STYLE_SUCCESS


        : \yiister\grid\widgets\ProgressColumn::STYLE_WARNING;


},

],

I tried this way:

$model->paxtashart

but it is jsut giving me 1 value for all attributes, it is not helping

'value'=>function($model){

    return $model->paxtashart;

},
