### Step 1: the modelDepending on your type of application (advanced or basic), create a new model **Asset** in **app\models** or, **backend\models** / **frontend\models** **common\models**.
```php
namespace common\models;
[...]
In _form.php (format as you like, in this case there's no html because I put this form in a modal with custom html and tags that can be confusing for the sake of the tutorial)```php
<?php
use yii\helpers\Html;
[...]
Now, the interesting part: ```php
use yii\web\UploadedFile;
use common\models\Asset;
public function actionCreate()
[...]
Name this action as you like. Basically this is the action that will render the file; now you'll see the reason of that "contentType" attribute.```php
/**
* Displays the asset as a blob
[...]
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>
