How to display information from two tables?

Question

MySQL

Good afternoon,
I am currently learning yii2.
There are two models i18n and Countries, both models correspond to tables and are inherited from ActiveRecord
Through Crud created actions, brought Data from two tables into the index.
At the moment I'm stuck on actionUpdate
Could you show by example how to display all fields from two tables in Update, but in the Countries table everything is simple (one line)
Example of i18n table

Standard code

public function actionUpdate($id)
    {
        $model = $this->findModel($id);

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            return $this->redirect(['view', 'id' => $model->country_id]);
        } else {
            return $this->render('update', [
                'model' => $model,
            ]);
        }
    }

Relationship of tables in Countries

public function geti18n(){
        return $this->hasMany(i18n::className(), [
            'object_id' => 'country_id',
        ]);
    }

Communication in i18n

public function getCountries()
    {
        return $this->hasOne(Countries::className(), ['country_id' => 'object_id']);
    }

Thanks in advance
