我前面的打印语句写错了：Yii::trace('userid is ',$userId); 。错误地写成,了，实际userid是有值的，我看了下，它的值竟然是username，就错在这里了。问题就出在这里了，应该是userid的，怎么值会变成username了。

$userId应该为1，不应该为admin。

我看了下mainl.php

'srbac' => array(
'userclass'=>'User', //default: User
'userid'=>'user_ID', //default: userid
'username'=>'username', //default:username

似乎也没有错，错在哪里呢？

userid的获取是在哪个文件里面呢？

我加的打印语句：Yii::trace('userid is ',$userId);应该没有错吧，就应该这样打印吧，但是日志中没有打印出来userid。

定位出是因为userid为空，
我打印出的：

2012/06/06 16:01:22 [trace] [admin] userid is 
in D:\skill\finance\Yii\protected\modules\srbac\components\SDbAuthManager.php (32)

in D:\skill\finance\Yii\protected\modules\srbac\components\SDbAuthManager.php (35)

userid为什么为空呢？它应该是在哪里赋值的呢？

class SDbAuthManager extends CDbAuthManager {

  public function checkAccess($itemName, $userId, $params=array()) {
    if (!empty($this->defaultRoles) && in_array($itemName,$this->defaultRoles)) {
      return true;
    }
    
    $sql = "SELECT name, type, description, t1.bizrule, t1.data, t2.bizrule AS bizrule2, t2.data AS data2 FROM {$this->itemTable} t1, {$this->assignmentTable} t2 WHERE name=itemname AND userid=:userid";
    $command = $this->db->createCommand($sql);
    $command->bindValue(':userid', $userId);
    Yii::trace('userid is ',$userId);
    // check directly assigned items
    $names = array();
    foreach ($command->queryAll() as $row) {
       Yii::trace('Checking permission "' . $row['name'] . '"', 'system.web.auth.CDbAuthManager');
      if ($this->executeBizRule($row['bizrule2'], $params, unserialize($row['data2']))
        && $this->executeBizRule($row['bizrule'], $params, unserialize($row['data']))) {
        if (strtolower($row['name']) === strtolower($itemName)) {
          return true;
        }
        $names[] = $row['name'];
      }
    }

似乎是我哪个地方做得不对，按照你的在SBaseController中添加public $menu=array();
又出了个新的错，怎么可能出这么多错呢？

自动生成的代码，怎么会有问题呢？要手动修改？那怎么修改呢

应该去掉其中的 !号，改为

if($model->hasAttribute('During'))
{
    .....
}

就OK 了，只要数据库表中有这个During字段，就会用During去过滤。没有During字段，也不会出问题。 我要的就是这种效果。

没有起效，为什么没有起效呢？每次 isset($model->During) 都是返回 false，即 $model->During=date('Y-m-01',strtotime('-5 month'))没有执行，这是为什么呢？
我的controller

public function actionAdmin()
{
    $model=new Test('search');
    $model->unsetAttributes();  // clear any default values
		
    if(isset($model->During))
        $model->During=date('Y-m-01',strtotime('-5 month'));
		
    if(isset($_GET['Test']))
        $model->attributes=$_GET['Test'];

    $this->render('admin',array(
        'model'=>$model,
    ));
}
