Using in GridView about yii2-attachments HOT 2 CLOSED

First of all you should use $file->url instead of $file->path. The next your problem is that the value of the column must be a closure returning a string. Your solution is the following code:

[
    'attribute' => 'files',
    'label' => false,
    'format' => 'raw',
    'value' => function($data) {
        $output = '';
        if (isset($data->files[0]))
            $output .= Html::img($data->files[0]->url);
        return $output;
    }
]

Thanks a million! The returning a string in the closure was my mistake in copying, but somehow, I had also overlooked the url method in your code. Again, many thanks for such an excellent extension!
