Relationship issue in YII - yii

Question

I Have a GetStudents function in Agent model. where I fetch the students related to the agents.
But I want to show more fields of students from another table
Eg
**Agent table** (agent has students)
agent_id
**student table**
STUDENTID pkey
agent_id
**relation table** (this table creates relation between student and household)
StudentID HOUSEHOLDID
**HOUSEHOLD TABLE**
HouseHOLDID Householdname
I want to fetch householdname when I fetch all student details.
really looking bazzare to me as I am newbie to YII
MY function in agent model.
public static function getStudents($id) {
$relationships = Relationship::model()->findAll('type = :type AND source = :agent_id', array(':type' => 2, ':agent_id' => $id));
//$relationships=sort($relationships);
// Generate relationship array
//print_r($relationships);
foreach ($relationships as $relationship) {
$in[] = $relationship->destination;
}
// Generate db condition
$criteria = new CDbCriteria;
if (! isset($in) || ! is_array($in) || sizeOf($in) == 0) {
$in[] = -999;
}
$criteria->addInCondition('StudentID', $in, 'OR');
return new CActiveDataProvider('Student', array(
'criteria' => $criteria,
'sort'=>array('defaultOrder'=>array(
'StudentID'=>CSort::SORT_DESC,
)),
));
}
My code to fetch data in by passing ID into it
<?php $this->widget('zii.widgets.CDetailView', array(
'data' => $model,
'attributes' => array(
array(
'label' => 'Agent Details',
'type' => 'raw',
'value' => '',
'cssClass' => 'heading',
),
'agent_id',
'user.email',
'first_name',
'last_name',
'company',
'phone',
),
)); ?>
Any help would be greatly appreicated.
Thanks

First you should make relation with student to relation table in relations array in relation model like this ..
'student'=>array(self::BELONGS_TO, 'Student', 'StudentID'), //after belongs to student is model class name
'household'=>array(self::BELONGS_TO, 'HOUSEHOLD', 'HOUSEHOLDID'),//after belongs to HOUSEHOLD is model class name
And then you can fetch all record with active record like this...
$relationships = Relationship::model()->with('student','household')->findAll('type = :type AND source = :agent_id', array(':type' => 2, ':agent_id' => $id));
