[转]关于Yii中CGridView关联表字段的filter问题解决方法
转载自:http://blog.sina.com.cn/s/blog_497d88270100qi4g.html
当你想用CGridView控件来生成一个Grid表格的时候,是非常方便的,你只需要简单的指定几个属性就可以了,比如:
首先,让关联表字段显示在Grid表格里面很容易,你可以在dataProvider属性加上关联表,然后columns属性里直接加上要显示的关联表属性就可以,比如,修改后的dataProvider为
'dataProvider'=>$model->with('relationNameToOtherTable
修改后的columns属性为:
'columns'=>array(
),
但这时的customer_nm是不具备filter域的
解决方法如下:(修改主表对应的Model类)
1)手动为主表增加关联表属性,public $this->customer_nm;
2) 修改search()方法,增加如下两行:$criteria->with = 'relationNameToOtherTable';//relationNameToOtherTable是你在relations里面定义的键值
$criteria->compare('customer_nm', $this->customer_nm);
3)增加afterFind()方法到主表的model类,方法内容如下:$this->customer_nm = $this->relationNameToOtherTable->customer_nm;
这时,你就可以不像前面写的那样修改dataProvider和columns了,因为你手动增加的那个属性已经把关联表的字段属性加进来了,直接用就可以了,最终view代码如下:
'dataProvider'=>$model->search();
'columns'=>array(
'id',
'customer_cd',
'customer_nm'=>array(
'name'=>'relationNameToOtherTable.customer_nm',
),
),
ok, that's all, not the best solution, but it works any way, well if you have some good ideas for this kind of problem feel free to tell me, thanks a lot!!
