How to add custom column in CGridView in 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.

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"', 
    ),
    ...
)
