Question

I’m trying to list with CGridView posts of a specified user, but is giving error. What is the correct method of doing this?

Controller.php

public function actionListPosts($id)
{
    $criteria = new CDbCriteria;
    $criteria->with=array('posts');
    $criteria->condition='t.id=:user_id';
    $criteria->params=array(':user_id'=>$id);

    $dataProvider=new CActiveDataProvider('Users', array(
            'criteria' => $criteria
    ));

    $this->render('list',array(
        'dataProvider'=>$dataProvider,
    ));
}

View.php:

<?php $this->widget('zii.widgets.grid.CGridView',array(
    'id'=>'events-grid',
    'dataProvider'=>$dataProvider->posts,
    'columns'=>array(
        'id',
        'name',
    ),
)); ?>

Error:

 Property "CActiveDataProvider.posts" is not defined.

Answer 1

You must use the dataprovider for Post model instead of User model

in controller

public function actionListPosts($id)
{
    $criteria = new CDbCriteria;
    $criteria->condition='t.user_id=:user_id';
    $criteria->params=array(':user_id'=>$id);

    $dataProvider=new CActiveDataProvider('Post', array(
            'criteria' => $criteria
    ));

    $this->render('list',array(
        'dataProvider'=>$dataProvider,
    ));
}

and in view

<?php $this->widget('zii.widgets.grid.CGridView',array(
    'id'=>'events-grid',
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        'id',
        'name',
    ),
)); ?>
