Question

I’m trying to join a relational table profiles at the CSqlDataProvider, but it’s not working property.

How can I have access to profiles.id in the view?

Controller.php:

$sql = "SELECT `events`.`id`
        FROM events
        LEFT OUTER JOIN `profiles` ON (`events`.`profile_id`=`profiles`.`id`)";

$dataProvider=new CSqlDataProvider($sql);

View.php:

<?php $this->widget('bootstrap.widgets.TbGridView',array(
    'type'=>'striped bordered condensed',
    'id'=>'events-grid',
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        'profiles.id', // Problem here, always returns NULL.
        'events.id',
    ),
)); ?>

1. First ofcourse you need to select the other field as already mentioned in Phillipe’s answer :

   SELECT `events`.`id`, `profiles`.`id` ...
   

2. It’ll be better to give profiles.id an alias because the both the column names are id:

   SELECT `events`.`id`, `profiles`.`id` as pid ...
   

3. Then in the grid you can access these columns as:

   'columns'=>array(
       'pid', // instead of profiles.id
       'id', // instead of events.id
   )
