Question

[The Dragger]

<?php $this->widget('bootstrap.widgets.TbGridView',array(
	'id'=>'ref-mahala-grid',
	'dataProvider'=>$model->search(),
	'filter'=>$model,
	'columns'=>array(
		'id',
		'district_id',
		'name_ru',
		'name_uz',
		'name_en',
		'address_ru',
		array(
			'class'=>'bootstrap.widgets.TbButtonColumn',
		),
	),
)); ?>

в дистрик_ид приходят ид , по этому ид я должен достать запись из подвязки.
Модель.

public function search()
	{
		// @todo Please modify the following code to remove attributes that should not be searched.

		$criteria=new CDbCriteria;

		$criteria->compare('id',$this->id);
		$criteria->compare('district_id',$this->region['name_ru']);
		$criteria->compare('name_ru',$this->name_ru,true);
		$criteria->compare('name_en',$this->name_en,true);
		$criteria->compare('address_ru',$this->address_ru,true);
		$criteria->compare('address_en',$this->address_en,true);
		$criteria->compare('sort',$this->sort);
		$criteria->compare('active',$this->active);

		return new CActiveDataProvider($this, array(
			'criteria'=>$criteria,
		));
	}
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(
			'region' => array(self::BELONGS_TO, 'RefRegion', 'district_id'),
		);
	}
