Getting unknown property in Yii

Question

under the course content there, I want to make the Active column to show either "Yes" or **"No"**At first it was showing "1" or "0", but that's not what I want to show. These are my attempted codes, and I'm getting this error. Appreciate it if anyone can please guide me.

Have to make 2 changes to your code.

1. Change all $model->isActive to $model->active.
2. Return "Yes" or "No" depending to $model->active value.

Update DetailView:

[
    'attribute' => 'active',
    'value' => function ($model) {
        return $model->active ? "Yes" : "No";
    },
    'contentOptions' => ['style' => $model->active ? 'color:green' :'color:red']
],

Update GridView:

[
    'attribute' => 'active',
    'value' => function ($model) {
        return $model->active ? "Yes" : "No";
    },
    'contentOptions' => function ($model, $key, $index, $column) { 
        return $model->active ? ['style' => 'color:green'] : ['style' => 'color:red']; 
    }
],
