How to display data from linked table in edit form?

Question

Yii

Available:

• table User with fields id (user id) and org (organization id from table Org) , User model;
  
• table Org with fields id (organization id) , name (organization name) , Org model;
  
• connection is configured in the User model (done via gii) :

  public function getOrg0()
      {
          return $this->hasOne(Org::className(), ['id' => 'org']);
      }

  
  
• a form for editing a record of the User table: ( app/modules/users/views/user/_form.php) which has a line for editing a field
  

  /* @var $model app\modules\users\models\User */
  .....
  <?= $form->field($model, 'org0.name')->textInput() ?>

  
  

The output is an error:
Getting unknown property: app\modules\users\models\User::org0.name
If we write like this,
<?= $form->field($model, 'org')->textInput() ?>
then the output is the organization id from the User table.
How to write a line correctly so that the output contains the name of the organization from the Org table?

Answer 1

<?= $form->field($model->org0, 'name')->textInput() ?>

Answer 2

Can you do it with a getter?
<?= $form->field($model, 'orgName')->textInput() ?>
...................
in the model:
public function getOrgName( ){ return $this->org0->name; }
