CGridView question

Yii 1.1 General Discussion
1

Hello everybody,

i have this CGridView, and i have this dataProvider object:




$dataProvider=new CActiveDataProvider("Arma", array(

    'criteria'=>array(

	'with'=>array('classeXArmas.classe'),

    ),

    'pagination'=>array(

	'pageSize'=>25,

    ),

));

as you can see each Arma is related many to many to Classe.

the problem is that i’m just able to show Arma’s fields in my grid like this:




$this->widget('zii.widgets.grid.CGridView', array(

	...

	'columns'=>array(

		array(

			"class" => "CLinkColumn",

			"labelExpression" => '$data->nome',

			"urlExpression" => '"profilo/".$data->id_arma',

			"header" => Yii::t("arma","LABEL-NOME"),

		),

		array(

			"name" => "prezzo",

			"value" => '$data->prezzo." €"'

		),

        ),

	...

));

Anybody can help me out with creating another column with the all the Classe->nome occurrences for each Arma row?

Maybe comma separated since there can be many of them for each Arma. I’m digging through documentation but i can’t make it work. I think this can be a useful how-to even for other newbies like me in the same situation.

I hope i’ve made it clear enough to make sense to you!

Thanks in advance

I suggest creating a method in your model class to retrieve the related values and present them as a comma separated list as you mentioned.




//Arma.php (Model)

public function getClasses(){

  return implode(',', $this->classes); 

}


//then in your gridview, something to this effect

'value'=>'$data->getClasses()'

Someone should correct me if I’m wrong about this, but I think I heard this somewhere. If you create a function in the ActiveRecord class such as getSomething(), that you can then treat this as an attribute? Like $model->something instead of $model->getSomething()? Either way, I think using a get method like this should do the trick of collecting all the related fields and allowing you to put that into your gridview.

Alright, I shouldn’t have been lazy. What I was saying at the end is true.




//model class:

public function getSomething(){ return 'something'; }


//view:

echo $model->something;

//same as

echo $model->getSomething();
