How to correctly write the update method for 2 models?

Question

Yii

The question is this: there is a method in the associated model that saves data to 2 tables at once

public function actionCreate()
  {

    $model=new Fio;
    $phone = new Phone;

    // Uncomment the following line if AJAX validation is needed
  //	 $this->performAjaxValidation($model);

    if(isset($_POST['Fio'], $_POST['Phone']))
    {
      $model->attributes=$_POST['Fio']; // сначало сохраняем fio
//			$model->Street_ID=6;
            $model->Street_ID = $_POST['Street_ID']; // затем говорим ему что Street_ID нужно брать из Street_ID которое обьявлено в DynamicStreets методе
      $phone->attributes=$_POST['Phone'];
      //$phone->Type_ID=2;
      //$phone->FIO_ID = $model -> $_POST['ID'];
            if(($model->save())){
                $phone->FIO_ID = $model-> ID;
                if ($phone->save())
                $this->redirect(array('view', 'id' => $model->ID));
      }

    }
        $this->redirect(array('index'));

  }

data is taken from the form of this model. I need to set up an Update for them, but I'm having trouble with the update form.

<div class="row">
        <?PHP echo CHtml::form();
        $data = CHtml::listData(Town::model()->findAll(), 'ID', 'Town'); // первое поле, тут запрашивается  город и его id
        echo CHtml::dropDownList('ID', '',$data,
            array(
                'prompt'=>'Select Region',
                'ajax' => array(
                    'type'=>'POST',
                    'url'=>Yii::app()->createUrl('Fio/dynamicStreets'), //ссылка на метод в контроллере
                    'update'=>'#Street_ID', //тэг для второго поля
                    'data'=>array('ID'=>'js:this.value'),
                )));
        echo CHtml::dropDownList('Street_ID','', array(), array('prompt'=>'Select City'));?>
  </div>

  <div class="row">
    <?php echo $form->labelEx($model,'Surname'); ?>
    <?php echo $form->textArea($model,'Surname',array('rows'=>1, 'cols'=>40)); ?>
    <?php echo $form->error($model,'Surname'); ?>
  </div>

  <div class="row">
    <?php echo $form->labelEx($model,'Patronymic'); ?>
    <?php echo $form->textArea($model,'Patronymic',array('rows'=>1, 'cols'=>40)); ?>
    <?php echo $form->error($model,'Patronymic'); ?>
  </div>

  <div class="row">
    <?php echo $form->labelEx($model,'Name'); ?>
    <?php echo $form->textArea($model,'Name',array('rows'=>1, 'cols'=>40)); ?>
    <?php echo $form->error($model,'Name'); ?>
  </div>

  <div class="row">
    <?php echo $form->labelEx($model,'Building'); ?>
    <?php echo $form->textField($model,'Building'); ?>
    <?php echo $form->error($model,'Building'); ?>
  </div>
    <div>
        <?php echo $form->labelEx($phone,'Number'); ?>
        <?php echo $form->textArea($phone,'Number',array('rows'=>1, 'cols'=>40)); ?>
        <?php echo $form->error($phone,'Number'); ?>
    </div>
    <div>
        <?php echo $form->labelEx($phone,'Type_ID'); ?>
        <?php echo $form->dropDownList($phone,'Type_ID', CHtml ::listData(Type::model()->findAll(), 'ID','Type_Phone')); ?>
        <?php echo $form->error($phone,'Type_ID'); ?>
    </div>

when i write

<?php $this->renderPartial('_form', array('model'=>$model,
  //  'phone'=>$phone
)); ?>

he swears at $phone, this renderer is in update view, the same renderer is registered in index, where it is accepted without problems. When you try to switch to update with this code, it says that $phone is from the form

<div>
        <?php echo $form->labelEx($phone,'Number'); ?>
        <?php echo $form->textArea($phone,'Number',array('rows'=>1, 'cols'=>40)); ?>
        <?php echo $form->error($phone,'Number'); ?>
    </div>

One to one connection?
Then you must also define $phone
and pass it on

$this->renderPartial('_form', array('model'=>$model, 'phone'=>$phone));
