Question

This 3 tables are just a part of my entire project (users,profile,login)

Login.php (model for login table)

public function topten_logins(){

    $criteria = new CDbCriteria;
    $criteria->select = 'concat(u.firstname," ",u.lastname) as Name, p.join_date as Joined, count(*) as Logins';
    $criteria->alias = 'l';
    $criteria->join = 'left join users u on (u.id = l.user_id) left join profile p on (p.user_id = l.user_id)';
    $criteria->group = 'l.user_id';
    $criteria->order = 'Logins desc';
    $criteria->limit = '10';

    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
    ));
}

and I have to display it in CGridView, and my code to display is as follows:

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

    'dataProvider'=>Login::model()->topten_logins(),
    'enablePagination' => false,
    'columns'=>array(
        'Name',
        'Joined',
        'Logins',
        array(
            'class'=>'CButtonColumn',
        ),
    ),
)); ?>

I just want to display Top ten users who have most logins.

But it gives me error message that:

Property “Login.Name” is not defined.

I haven’t used Yii before. So, your help will be highly appreciated.

Answer 1

The problem is you are making query with ‘as Name and as Logins’. In this case, what you need to do is to define ‘Name’ and ‘Logins’ as a variable in your model. in the class definition of your model add

public $Name;
public $Logins; 

And it should work.
