Getting the Article title for the Comment Crud

Question

I created an Article and Comment Models and have CRUD on both. Its works perfectly. What I need now is to have the article.title field displayed in Comment Crud instead of the comment.articleid. How can I do that?

This is where I'm stuck. I don't know what to do next or if that's correct:

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(
        'article'=>array(self::BELONGS_TO, 'Article', 'articleid')
    );
}

EDIT:

Here's my code admin.php view file:

<?php $this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'comment-grid',
    'dataProvider'=>$model->search(),
    'filter'=>$model,
    'columns'=>array(
        'commentid',
        'articleid',
        'content',
        'author',
        'email',
        array(
            'class'=>'CButtonColumn',
        ),
    ),
)); ?>

Thanks.

Answer 1

it would be something like this for the columns array:

'columns'=>array(
        'commentid',
        array(
            'name'=>'title',
            'value'=>'$data->article->title',
            'type'=>'text'
        ),
        'content',
        'author',
        'email',
        array(
            'class'=>'CButtonColumn',
        ),
    ),
