Yii Counter查询Findall

Question

I have the following query

UserLogin::model()
-> with(array(
    'Provider'=> array(
        'select'=>'name'
    )
))
-> findAll(array(
    'select' => 'count(t.id) as count ',
    'group'=>'provider_id',
    'order'=>'provider_id'
));

and my view is

<?php foreach($providerCounts as $providerCount): ?>
    <tr>
        <td><?php echo $providerCount['Provider']['name']; ?></td>
        <td><?php echo $providerCount['count']; ?></td>             
    </tr>
<?php endforeach; ?>

Here is the relation

'Provider'=>array(self::BELONGS_TO, 'Provider', 'provider_id'),

I am getting the error

Property "UserLogin.counts" is not defined.

The same query in a different model is working.

Now i have two question

• Why is the query not working
• How do i debug such errors in yii

Answer 1

您需要具有UserLogin.count属性，以便当您在AR请求中使用as时，Yii可以将返回的DB值分配给模型。

Answer 2

You need specify public property count

class UserLogin extends CActiveRecord
{
    public $count = 0;

    public function rules() {
        // ...
        array('count', 'safe'),
        // ...
    }
}

For debug use xdebug for php + ext for FireFox for debugging php

Also use yii-debug-toolbar (search in yii ext site)
