when to use cActiveDataProvider

Yii 1.1 General Discussion
1

This might be obvious to some people but im a bit lost here :blink:

Whats the guidelines here when are you supposed to use a CActiveDataProvider.

is it only when using like a cgridview etc ?

Im not sure I totally understand the dataprovider is there any extended documentation about this "feature"

Also it would make more sense to just a add a list of object to the view whats the benefit of the dataprovider ?

i want to know too~

CGridView, CListView, and related widgets require it. The combination of CActiveDataProvider and the widget makes sorting and pagination easy. Maybe there’s more to it than that; I don’t know.

Here is a data provider that takes an array of CActiveRecords in the config:




class CArrayDataProvider extends CDataProvider {

	public $dataArray;

	public $modelClass;

	

	public function __construct($confModelClass, $config)

	{

		$config = new CConfiguration($config);

		$config->applyTo($this);

		$this->modelClass=$confModelClass;

	}

	

	protected function fetchData() {

		$startIndex=0;

		$length=$this->getTotalItemCount();

		if(($pagination=$this->getPagination())!==false)

		{

			$pagination->setItemCount($this->getTotalItemCount());

			$length=$pagination->pageSize;

			$startIndex=$pagination->currentPage*$pagination->pageSize;

		}

		return array_slice($this->dataArray, $startIndex, $length, true);

	}

	

	protected function fetchKeys() {

		return array_keys($this->getData());

	}

	

	protected function calculateTotalItemCount() {

		return count($this->dataArray);

	}

}

Usage for example:




$dataProvider=new CArrayDataProvider('Producer', array(

	'dataArray'=>$model->producers,

	'pagination'=>array(

		'pageSize'=>10,

	)

));

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

	'dataProvider'=>$dataProvider,

	'itemView'=>'application.views.producer._listItemView',

));

SOLVED http://www.yiiframework.com/forum/index.php?/topic/7678-zii-for-non-active-records/

Hi there.

I have a problem:

There is 2 arrays, first for the column names (example):




$names['closed'] = 'Done';

$names['active'] = 'In progress';

and array of values:




$values['Type1']['closed'] = 35;

$values['Type1']['active'] = 23;

$values['Type2']['closed'] = 55;

$values['Type2']['active'] = 575;

$values['Type3']['closed'] = 44;

$values['Type4']['active'] = 325;

I need to show it in CGridView like this:


     |In Progress|Done

Type1|    23     |  35

Type2|    575    |  55

Type3|    0      |  44

Type4|    325    |  0

Is it possible?
