```php
use yii\web\UploadedFile;
use common\models\Asset;

```php
/**

In order to render the file - let's say, an image - , apply this code in any view:
```php
use yii\helpers\Html;
use yii\helpers\Url;[...]
```php
use yii\helpers\Html;
use yii\helpers\Url;
<?php if(strpos($model->contentType,'image')===false): //Not an image?>
<iframe src="<?=Url::to(['asset/get', 'id'=>(string)$model->_id]);?>" width="100%" height="600px"></iframe>[...]
