显示结果gridView cbdCriteria联接

Question

我在将JOIN中的表与CDbCriteria关联时遇到问题。我可以在两个相关的表之间使用单个JOIN来工作，但是有以下情况：

具有相关字段的表的结构：

SQL：

SELECT
  `rec`.`idrecibo` AS 'Num_Recibo',
  `dom`.`matricula`,
  `dom`.`federado`,
  `ent`.`nombre` AS 'profesional',
  `dom`.`calle` AS 'domicilio'
FROM
  `tbl_recibo` AS rec
    LEFT JOIN `tbl_domicilio` AS dom ON `rec`.`iddomicilioapertura` = `dom`.`iddomicilio`
    LEFT JOIN `tbl_entidad` AS ent ON `dom`.`identidad` = `ent`.`identidad`

yii：

public function traerRecibos() {
    $r = new CDbCriteria();
    $dx = TblDomicilio::model()->tableName();
    $ex = TblEntidad::model()->tableName();
    $r->select='t.idRecibo,DX.idDomicilio';
    $r->join = 'left join ' . $dx . ' DX on DX.idDomicilio = t.idDomicilio';
    $r->join = 'left join ' . $ex . ' EX on EX.idEntidad=DX.idEntidad';
    return new CActiveDataProvider($this, array(
        'criteria' => $r,
        'pagination' => array('pageSize' => Yii::app()->user->getState('pageSize', Yii::app()->params['defaultPageSize']),
    )));
}

关系表tblRecibo：

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(
        'tblEstadoreciboHasTblRecibos' => array(self::HAS_MANY, 'TblEstadoreciboHasTblRecibo', 'idRecibo'),
        'tblItemrecibowebs' => array(self::HAS_MANY, 'TblItemreciboweb', 'idRecibo'),
        'idCalendario0' => array(self::BELONGS_TO, 'TblCalendario', 'idCalendario'),
        'idDomicilioApertura0' => array(self::BELONGS_TO, 'TblDomicilio', 'idDomicilioApertura'),
        'idDomicilio0' => array(self::BELONGS_TO, 'TblDomicilio', 'idDomicilio'),
        'idPaquete0' => array(self::BELONGS_TO, 'TblPaquete', 'idPaquete'),
    );
}

查看索引tblRecibo模型：

$this->widget('bootstrap.widgets.TbGridView', array(
    'type' => 'bordered striped',
    'id' => 'tbl-recibo-grid',
    'dataProvider' => $dataProvider,
    'htmlOptions' => array('style' => 'font-size: 16px;font-weight: normal'),
    'columns' => array(
        array(
            'name' => 'idRecibo',
            'header' => 'N°Recibo',
            'headerHtmlOptions' => array('style' => 'width: 10px'),
        ),
        array(
            'name' => 'idDomicilio',
            'header' => 'Matricula',
            'value' => 'isset($data->idDomicilio0->matricula)?$data->idDomicilio0->matricula:""',
            'headerHtmlOptions' => array('style' => 'width: 15%'),
        // 'filter' => CHtml::listData(TblDomicilio::model()->findAll('idDomicilio', 'nombre'),
        ),
));
?>

我需要在视图中显示与tblRecibo没有直接关系的tblEntity表的“名称”字段的值。
