How to add custom column in CGridView in YII? - yii

Question

I need to add a column in CGridView.
I use this:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'user-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'pager' => array(
'firstPageLabel' => '<<',
),
'columns'=>array(
'username',
'name',
'email',
'creationDate',
array(
'class' => 'CButtonColumn',
'template' => '{change} {view}',
'buttons' => array(
'change' => array(
'url'=> "'http://test.com/userservice/".$model->username."'",
),
),
),
array(
'name' => 'test',
'value' => 'testtest',
)
),
));
But I got error:
Property "User.test" is not defined.

Answer 1

You're almost there, in your column array you would use the name param for attributes of the model in the dataprovider, instead for custom columns you can use header like so:
'columns'=>array(
...
array(
'header' => 'test',
'value' => '"testtest"',
),
...
)

Answer 2

You can write normal code on CGridView like this .
'columns'=>array(
'username',
'name',
'email',
'creationDate',
'test',
---
),
If you put code like this on your respective model .
---
public $test ;
public function afterFind() {
$this->test = 'Test Variable' ; // put your custom code to reflect exact need
return parent::afterFind();
}
