Rut Formatting

Load the behavior in the config/web.php:

'formatter' => [
    'class' => \yii\i18n\Formatter::className(),
    'as rutFormatter' => \sateler\rut\RutFormatBehavior::className(),
],

Or if you use another formatter class, add the behavior:

public function behaviors() {
    return [ \sateler\rut\RutFormatBehavior::className() ];
}

Then you can use Yii::$app->formatter->asRut(), or specify the rut format in GridView or DetailView.

Rut Validator

In your model rules, add:

['property', \sateler\rut\RutValidator::className()]

Rut Widget

To format input data in textInputs, in your app assets, add:

public $depends = [
    ...,
    'sateler\rut\RutWidgetAsset',
];

And activate the text input using:

$form->field($model, "rut")->textInput(['data-rut' => 'true'])

Upgrade from 1.x to 2.x:

Just replace references to RutValidator::trimValue($value) to the new function Rut::normalize($value)
