/**
 * SluggableBehavior automatically fills the specified attribute with a value that can be used a slug in a URL.
 *
 * To use SluggableBehavior, insert the following code to your ActiveRecord class:
 *
 * ```php
 * use yii\behaviors\SluggableBehavior;
 *
 * public function behaviors()
 * {
 *     return [
 *         [
 *             'class' => SluggableBehavior::className(),
 *             'attribute' => 'title',
 *             // 'slugAttribute' => 'slug',
 *         ],
 *     ];
 * }
 * ```
 *
 * By default, SluggableBehavior will fill the `slug` attribute with a value that can be used a slug in a URL
 * when the associated AR object is being validated.
 *
 * Because attribute values will be set automatically by this behavior, they are usually not user input and should therefore
 * not be validated, i.e. the `slug` attribute should not appear in the [[\yii\base\Model::rules()|rules()]] method of the model.
 *
 * If your attribute name is different, you may configure the [[slugAttribute]] property like the following:
 *
 * ```php
 * public function behaviors()
 * {
 *     return [
 *         [
 *             'class' => SluggableBehavior::className(),
 *             'slugAttribute' => 'alias',
 *         ],
 *     ];
 * }
 * ```
