Yii Framework 1.1 CdbCriteria在GridView中具有多个JOIN

我从版本1.1的世界Yii框架开始,对我来说,无法可视化纯查询带来的记录。我无法解决问题已经有好几天了,这可能很简单,但是由于我的知识不足,我还无法解决它。我向您展示我的代码,看看您是否可以帮助我。

我想在其中进行查询的TblRecibo模型的关系是:

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'),
    );
}

我的模特:

public function search()
{      
    $criteria = new CDbCriteria;
    $criteria->alias = 'r';
    $criteria->select = 'r.idRecibo,d.matricula,d.federado,e.nombre,d.calle,r.cantidad,cal.periodo,est.ult_modif,os.nombre ';
    $criteria->join ='LEFT JOIN tbl_calendario as cal on r.idcalendario=cal.idcalendario '
            .'LEFT JOIN tbl_estadorecibo_has_tbl_recibo as est on r.idrecibo=est.idrecibo '
            .'LEFT JOIN tbl_domicilio as d ON r.iddomicilioapertura=d.idDomicilio '
            .'LEFT JOIN tbl_entidad as e ON d.idEntidad=e.idEntidad '
            .'LEFT JOIN tbl_itemreciboweb as rweb on r.idrecibo=rweb.idrecibo '
            .'LEFT JOIN tbl_ooss as os on rweb.idooss=os.idooss';
    return new CActiveDataProvider($this, array(
        'criteria' => $criteria,
        'pagination' => array('pageSize' => Yii::app()->user->getState('pageSize', Yii::app()->params['defaultPageSize']),
        ),
    ));
}

我的控制器:

public function actionIndex()
{
    $model = new TblRecibo('search');
    $model->unsetAttributes();  // clear any default values
    if (isset($_GET['TblRecibo']))
        $model->attributes = $_GET['TblRecibo'];
    $this->render('admin', array(
        'model' => $model,
    ));
}

我的观点:

<?php
 $this->widget('bootstrap.widgets.TbGridView', array(
   'type'=>'bordered striped',
    'id' => 'tbl-recibo-grid',
    'dataProvider' => $model->search(),
    'htmlOptions'   =>array('style' => 'font-size: 16px;font-weight: normal'),
    'columns' => array(
        'idrecibo',
        'dom.matricula',
        'dom.federado',
        'ent.nombre',
        'dom.calle',
        'rec.cantidad',
        'cal.periodo',
        'est.ult_modif',
        'os.nombre',
    ),
));
?>

执行时,我没有错误,只是GridView没有显示查询结果。我知道应该没有什么复杂的,因为调试值是我不知道如何将其传递给Vista的问题。

使用r.idRecibo,d.matricula,d.federado, ...之类的select时,将返回诸如idRecibomatriculafederado等键的结果。要处理此类查询,您需要添加联接表中的所有字段到您的模型:

TblRecibo extends CActiveRecord {

    public $matricula;
    public $federado;
    // ...
}

然后在网格视图中通过以下方式访问它们:

'columns' => array(
    'idRecibo',
    'matricula',
    'federado',
    // ...
),

但是对于此类自定义查询,使用CSqlDataProvider而不是CActiveDataProvider可能会更容易-您将无需为该搜索添加模型属性-结果将以数组形式返回:

public function search() {      
    $from = 'FROM tbl_recibo as r '
            . 'LEFT JOIN tbl_calendario as cal on r.idcalendario=cal.idcalendario '
            . 'LEFT JOIN tbl_estadorecibo_has_tbl_recibo as est on r.idrecibo=est.idrecibo '
            . 'LEFT JOIN tbl_domicilio as d ON r.iddomicilioapertura=d.idDomicilio '
            . 'LEFT JOIN tbl_entidad as e ON d.idEntidad=e.idEntidad '
            . 'LEFT JOIN tbl_itemreciboweb as rweb on r.idrecibo=rweb.idrecibo '
            . 'LEFT JOIN tbl_ooss as os on rweb.idooss=os.idooss';
    $count = Yii::app()->db->createCommand('SELECT COUNT(*) ' . $from)->queryScalar();
    $sql = 'SELECT r.idRecibo,d.matricula,d.federado,e.nombre,d.calle,r.cantidad,cal.periodo,est.ult_modif,os.nombre ' . $from; 

    return new CSqlDataProvider($sql, array(
        'totalItemCount' => $count,
        'pagination' => array(
             'pageSize' => Yii::app()->user->getState('pageSize', Yii::app()->params['defaultPageSize']),
        ),
    ));
}
