Yii CGridView handle special cases using model function

Question

Having some trouble with CGridView on Yii Framework...

I'm looking to replace the contents of a column based on the value it holds. I need to handle special cases so I added a function into the model to return a value to the GridView. I get the resulting error " Undefined variable: model ".

I'm sure it's likely something simple. Is it because my dataProvider is not model?

Here is a shortened version of my code:

<?php
/* @var $this BookController */
/* @var $dataProvider CActiveDataProvider */
/* @var $model Book */

<?php $this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'book-grid',
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        array(
            'name'=>'userName',
            'header'=>'Name',
            ),
        array(
            'name'=>'status',
            'header'=>'Status',
            'type'=>'raw',
            'value'=>array($model, 'statusText')
            ),
    )
));

?>

And here is code in models/Book.php

class Book extends CActiveRecord
{
    ...
    ...

    public function statusText($data, $row) {
        $content = '';

        if (CHtml::encode($data->status) == "processed") {
            $content = "Process completed";
        }
        else if ($data->status=="") {
            $content = "Queued for Processing";
        }
        else {
            $content = CHtml::encode($data->status);
        }

        return $content;
    }

    ...
    ...
}

Here is a simplified example from my current project;

    <?php

    //My controller
    class NewsController extends CController {


//The admin action
        public function actionAdmin() {
            $model = new News;

            $this->render('admin', array(
                'model' => $model
            ));
        }

    }

    //In my view file
    $this->widget('ext.widgets.MyTbGridView', array(
        'dataProvider' => $model->search(),
        'columns' => array(
            array(
                'name' => 'id',
                'filter' => false,
            ),
            array(
                'name' => 'title',
            ),
            array(
                'value' => array($model, 'gridDate')
            ),
        ),
    ));

    //My model function
    class News extends CActiveRecord {

        public function gridDate($data, $row) {
            return 'Date formatted!';
        }

    }
    ?>

The code 'value' => array($model, 'gridFormatDate'), is important. there are two possibilities here. The function can reside in the controller, in which case it should be 'value' => array($this, 'gridFormatDate'), or it can be in the model, in which case the correct code is given

Answer 2

In stead of array($model, 'statusText'), try '$data->statusText'.

The method in your model should be like this:

public function getStatusText() {
        $content = '';

        if (CHtml::encode($this->status) == "processed") {
            $content = "Process completed";
        }
        else if ($this->status=="") {
            $content = "Queued for Processing";
        }
        else {
            $content = CHtml::encode($this->status);
        }

        return $content;
    }
