Yii - CGridView activerecord relation - yii

Question

I need to print out the result in CActiveDataProvider with CGridView and with pagination
The following is my function in model
public function getCompaniesJobsByCompanyId ( $companyId )
{
$criteria = new CDbCriteria(array(
'with'=>array(
'jobs'=>array(
'scopes' => array( 'offline' => array(0), ),
'vacancies'=>array(
'scopes'=>array(
'removed' => array(0),
'archived' => array(0),
),
),
),
),
'condition' => $this->getTableAlias(false) . '.company_id = ' . (int) $companyId,
)
);
$criteria->together = true;
$dataProvider = new CActiveDataProvider($this, array(
'criteria' => $criteria,
'pagination' => array(
'pageSize' => 20, //Yii::app()->params['pageSize'],
),
));
return $dataProvider;
}
How could be the CGridView to render my data?
By this way I iterate the result
$dataProvider = Employers::model() -> getCompaniesJobsByCompanyId(2);
foreach ( $dataProvider->getData() as $data ) {
echo $data['name'];
foreach ( $data->jobs as $jobs ) {
echo ' ---- ' .($jobs->employer_id) . ' ---- ';
foreach ( $jobs->vacancies as $vacancies ) {
echo '<br />' . ($vacancies->id) . '<br />';
}
}
}
And My view
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'user-grid',
'dataProvider' => $dataProvider,
'columns'=>array(
'title', // display the 'title' attribute
'id', // d
array(
'name'=>'job id',
//'value'=> '$data->jobs[0]["id"]',
//'value'=> 'jobs.id',
//'type' => 'raw'
),
array(
'name'=>'vacancy id',
//'value'=> '$data->jobs[0]->vacancies[0]->id',
//'value'=> 'print_r($data->jobs[0])',
'value'=> '$data->jobs["id"]',
//'type' => 'raw'
),
array(
'name'=>'employer name',
'type'=>'raw', // to encode html string
'value'=>'$data->name',
),
),
));
Any one can help me to print the values in jobs and vacancies relations?
UPDATE
I tried adding 'value' => '$data->jobs->id' but get an error Trying to get property of non-object
Update :
I tried 'value' => '$data->jobs[0]["id"]' and it display the the result correctly, but if there are only 1 record on the table. When there is more than 1 record on the table,
I need to print all result, how to loop on it ?

Answer 1

This line 'value' => '$data->jobs->id' raised an error Trying to get property of non-object because you have been permitted to accessed the property of object instead of array of objects (jobs)
The workaround is you declare a function to do the task on the controller which rendered your gridview
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
...
array(
'name'=>'newColumn',
//call the method 'gridDataColumn' from the controller
'value'=>array($this,'gridDataColumn'),
'type'=>'raw'
)
),
));
class MyController extends Controller
{
//called on rendering the column for each row
protected function gridDataColumn($data,$row)
{
$cellResult = "";
//do your loop here
//example
foreach ( $data->children as $child ) {
$cellResult .=$child->id . "<br/>";
$cellResult .=$child->name . "<br/>";
}
return $cellResult ;
}
...
}
