Yii2 translation of dynamic content from the database - does not see the method from another model?

Question

Yii

Good time everyone, please tell me what I'm doing wrong?
the article model does not see the method specified in article_lang, and data is not displayed in the index ???
to implement the translation of the dynamic content of the pages stored in the database,
I created 2 tables article and article_lang, created models and wrote links
for article

public function getArticles(){
        return $this->find()->all();
    }
public function getDataArticles(){
        $language = Yii::$app->language;
        $data_lang = $this->getArticleLangs()->where(['lang_url'=>$language])->one();
        return $data_lang;
    }
public function getArticle($id){
        return $this->find()->where(['id' => $id])->one();
    }

for article_lang model

public function getArticleLangs()
    {
        return $this->hasOne(Article::class, ['id' => 'post_id']);
    }

added to controller

public function actionIndex(){
    $article = new Article();
    return $this->render('index', [
            'articles' => $article->getArticles(),
    ]);
}
public function actionView($id)
    {  $article = Article::findOne($id);
       $lang_data = $article->getDataArticles();
       return $this->render('single', [
            'article' => $article,
            'lang_data' => $lang_data,
]);
    }

when outputting to index, it
<?php $lang_data = $article->getDataArticles(); ?>
