Php 如何在Yii中的筛选器中指定tablename？

有两个表，

attendee

和

group

。两者都有一个

gender

字段。每个与会者被分配到一个小组。我的

CGridView

成功地显示了与会者的人数，但是当我添加代码以过滤性别时，我得到了以下错误。要计算组中的与会者数量，我手动执行加入；但是，联接使“性别”字段变得模棱两可。有没有办法在筛选器中指定它应该使用“t”或基表

当我加载视图时，它运行正常；当我单击对性别进行排序时，会显示以下消息：

错误消息 视图代码

$this->widget（'zii.widgets.grid.CGridView'，数组(
'id'=>'group-grid'，
'dataProvider'=>$model->search（），
“过滤器”=>$model，
'列'=>数组(
“姓名”，
排列(
'姓名'=>'性别'，
“value'=>”组：：$genderLabels[$data->gender]，
'filter'=>组：：$genderLabels，//啊！我知道了

更改了型号代码中的此行：

$criteria->compare（'gender'，$this->gender，true）；

到

$criteria->compare（'t.gender'，$this->gender，true）；
