/**
 * CrudController implements a common set of actions for supporting CRUD for ActiveRecord.
 *
 * The class of the ActiveRecord should be specified via [[modelClass]], which must implement [[\yii\db\ActiveRecordInterface]].
 * By default, the following actions are supported:
 *
 * - `index`: list of models
 * - `view`: the details of a model
 * - `create`: create a new model
 * - `update`: update an existing model
 * - `delete`: delete an existing model
 *
 * You may disable some of these actions by overriding [[actions()]] and unsetting the corresponding actions.
