View.php Value Of Related Table

Hello,

I have a view that shows the values of a table, but I have a related table and one value should be taken from that related table.

Currently the view shows fid_os of table server. But I need the reference of fid_os in table operatingsystem with the row os_name.

table operatingsystem with the cells id_os and os_name

here is my view view.php


<?php

/* @var $this ServerController */

/* @var $model Server */


$this->breadcrumbs=array(

	'Servers'=>array('index'),

	$model->id_server,

);


$this->menu=array(

	array('label'=>'Server anzeigen', 'url'=>array('index')),

	array('label'=>'Server erstellen', 'url'=>array('create')),

	array('label'=>'Server aktualisieren', 'url'=>array('update', 'id'=>$model->id_server)),

	array('label'=>'Server löschen', 'url'=>'#', 'linkOptions'=>array('submit'=>array('delete','id'=>$model->id_server),'confirm'=>'Sind Sie sicher das Sie diesen Server löschen wollen?')),

	array('label'=>'Server verwalten', 'url'=>array('admin')),

);

?>


<h1>Serveranzeige <?php echo $model->id_server; ?></h1>


<?php $this->widget('zii.widgets.CDetailView', array(

	'data'=>$model,

	'attributes'=>array(

		'id_server',

		'fid_os',

		'is_virtual',

		'os_version',

		'backup',

	),

)); ?>



Here is my model Server.php


	public function relations()

	{

		// NOTE: you may need to adjust the relation name and the related

		// class name for the relations automatically generated below.

		return array(

			'fidOs' => array(self::BELONGS_TO, 'Operatingsystem', 'fid_os'),

		);

	}

Here is my controler ServerController.php


<?php


class ServerController extends Controller

	/**

	 * using two-column layout. See 'protected/views/layouts/column2.php'.

I found the solution for the view.php file. It is the array(‘name’…


<?php $this->widget('zii.widgets.CDetailView', array(

	'data'=>$model,

	'attributes'=>array(

		'id_server',

                array(

                    'name'=>'fid_os',

                        'value'=>isset($model->fidOs)?CHtml::encode($model->fidOs->os_name):"unknown"

                ),

                'is_virtual',

                'os_version',

		'backup',

	),

)); ?>



But now I found that I also need a similar solution for my _view.php that is called from index.php.

Instead of the value of fid_os I would like to get the value of os_name of the related table Operatingsystem.

Can please somebody help me?

_view.php


<?php

/* @var $this ServerController */

/* @var $data Server */

?>


<div class="view">

	<b><?php echo CHtml::encode($data->getAttributeLabel('fid_os')); ?>:</b>

	<?php echo CHtml::encode($data->fid_os); ?>

	<br />

</div>

Shouldn’t it be the same?





isset($data->fidOs)?CHtml::encode($data->fidOs->os_name):"unknown"



Have you read Yii guide on AR relational queries?

Thank you the replay.

But it still does not work. The output is always unknown.


<b><?php echo CHtml::encode($data->getAttributeLabel('fid_os')); ?>:</b>

	<?php echo isset($model->fidOs)?CHtml::encode($model->fidOs->os_name):"unknown"; ?>

	<br />

I have read the documentation, but I don´t find the solution.

Do you have values filled in the db?

Did you try eager loading to check relation data is filled?

Yes, I have values in the database. My file view.php is working.

The file _view is read by the index.html file.


<?php

/* @var $this ServerController */

/* @var $dataProvider CActiveDataProvider */


$this->breadcrumbs=array(

	'Server',

);


$this->menu=array(

	array('label'=>'Server hinzufuegen', 'url'=>array('create')),

	array('label'=>'Server verwalten', 'url'=>array('admin')),

);

?>


<h1>Server</h1>


<?php $this->widget('zii.widgets.CListView', array(

	'dataProvider'=>$dataProvider,

	'itemView'=>'_view',

)); ?>



Please try to eagerly load $dataProvider with [size=2]fidOs relation values.[/size]

Thank you for your help.

I found the problem. I was using $model, but I need $data.


	<b><?php echo CHtml::encode($data->getAttributeLabel('fid_os')); ?>:</b>

	<?php echo isset($data->fidOs)?CHtml::encode($data->fidOs->os_name):"unknown"; ?>

	<br />

Great. Didn’t put enough attention to your last example :)
