Retrieve a CActiveDataProvider with a criteria in yii

Question

I'm starting with yii and I have some trouble when trying to filter an CActiveDataProvider with a criteria.

This is my database model:

Table            Columns
Project          [id, name, status]
userToProject    [user_id,project_id,role]
User             [id , ....]

And I'd like the index action to show all the projects with status=finished or where the user is currently assigned to that project.

So hard-coding the user id for testing purposes. This is my code:

$criteria=array(
            'order'=>'status desc',
            'with'=>array(
               'userToProject','userToProject.user'=>array('alias'=>'user')),
    );
$criteria['condition']='status=='.Project::STATUS_FINISHED;
$criteria['condition'].=' OR user.id = 6';
$dataProvider=new CActiveDataProvider('Project', array(
            'criteria'=>$criteria,
    ));
$this->render('index',array(
            'dataProvider'=>$dataProvider,
    ));

But it throws an Exception saying Unknown column 'user.id. What am I missing? Thanks

Edit: The error code is:

 Column not found: 1054
 Unknown column 'users.user_id' in 'where clause'. The SQL statement executed was: 
 SELECT `t`.`id` AS `t0_c0`, `t`.`name` AS `t0_c1`, `t`.`description` AS `t0_c2`, 
 `t`.`status` AS `t0_c3`, `t`.`creation_date` AS `t0_c4` FROM `pgp_project` `t` WHERE
  (status=4 OR users.user_id=6) ORDER BY status desc LIMIT 10

Try this

$criteria=new CDbCriteria(array(                    
    'order'=>'status desc',
    'with'   => array('userToProject'=>array('alias'=>'user')),
    'condition'=>'status='.Project::STATUS_FINISHED.' OR user.id = 6',
));

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

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