Module translations

As separate entities, modules should contain their own message files separate from your application message files. The recommended way to use messages within modules is as follows:

1. Within the init() method of your module, define a new translation section for your module:

   parent::init();Yii::$app->i18n->translations['modules/mymodule*'] = [
       'class' => 'yii\i18n\PhpMessageSource',
       'sourceLanguage' => 'en-US',
       'basePath' => '@app/modules/mymodule/messages'
   ];

2. Create a static method wrapper for Yii::t():

   public static function t($category, $message, $params = [], $language = null)
   {
       return Yii::t('modules/mymodule/' . $category, $message, $params, $language);
   }

3. Finally, create a separate message configuration file within the messages/ directory of your module that specifies the translator to be <ModuleName>::t:

   <?php return [
       'sourcePath' =>...
