用yii中的条件检索CActiveDataProvider

Question

我以yii开头，尝试使用条件过滤CActiveDataProvider时遇到了一些麻烦。

这是我的数据库模型：

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

而且我喜欢指数行动来显示所有与状态=完成或者用户当前分配给该项目的项目。

因此为测试目的硬编码用户标识。这是我的代码：

$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, 
    )); 

但它抛出一个异常说未知列“USER.ID。我错过了什么？由于

编辑：错误代码是：

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 

Answer 1

试试这个

$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, 
));
