Problem with ActiveRecord Relations

i have two tables :




TAccount


code	description	catid

-----------------------------

101	CASH		1

102	BANK		1

103	GIRO		1

201	AP		2




TCatAccount


catid	catdescription

-----------------------------

1	ACTIVA

2	PASIVA



Model:




* TAccount.php


class TAccount extends CActiveRecord

{

	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(

			'cat'=>array(self::BELONGS_TO,'TCatAccount','catid),

		);

	}




}


* TCatAccount.php


class TCatAccount extends CActiveRecord

{

	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(

			'account' => array(self::HAS_MANY,'TAccount','catid'),

		);

	}




}



and then i call activerecord data :




$model= TActakun::model()->with('cat')->findAll();

// next procedure



but data not display.

how to solve it ?

What is TActakun?

Try




$model= TAccount::model()->with('cat')->findAll();

print_r($model);



Tipp: Enable a log route to see if the correct sql statement is generated/executed.

when i tried to debug with :




print_r($model)



data display.

but, i want to display $model data to CGridView




public function actionCoa(){

			$model= TAccount::model()->with('cat')->findAll();

			print_r($model);

        	

			if(isset($_GET['TAccount']))

				$model->attributes=$_GET['TAccount'];

				

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

		}



and view code:




<?php 

$provider=$model->search();

$provider->pagination->pageSize=30;


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

	'id'=>'TAccount-grid',

	'dataProvider'=>$provider,

	'filter'=>$model,

	'columns'=>array(

		'code',

		'description',



and data not display in CGridView

You misunderstood the meaning of $model->search().

Check the code Gii generates. $model is the filter instance (new empty instance or populated with what’s subsequently posted from the search form). When calling search() in the model TAccount, the filter instance is used in building the criteria, the type of $model is used for parameter 1 to the CActiveDataProvider constructor.

In your case, add the with part to the criteria in the search() method of TAccount. Note that search() will return a CActiveDataProvider instance.

If you don’t need search functionality you can do like this and just pass $provider to the dataProvider property of CGridView (omit the filter property):




$provider = new CActiveDataProvider('TAccount', array(

  'criteria' => array(

    'with' => 'cat',

  ),

  'pagination' => array(

    'pageSize' => 30,

  ),

));



As a side note, you can achieve a similar array of models like what’s returned from findAll() in your controller example by calling $provider->getData(true).

In the ancient days of Yii 1.0 we added discrete pieces of code in the controller, like criteria, pagination and sort objects, making a count() call to establish pagination as well as offset and limit to the criteria, finally calling findAll() in order to get the array of AR objects. All of this is now handled inside CActiveDataProvider and placed in the models search() method.
