Yii的srbac拓展中“用户已经获授权项”无法查看

Yii的srbac拓展中“用户已经获授权项”点下拉框，选择一个有权限的用户时，根本无法列出权限。

原因是srbac把数据库的表中的ID默认为数字，像 123这样，但如果不是数字像这样 'y0f22ffc2fef712fd602a1ef64ab319t' 。那么这个是不会出来的，那么只能修改代码 了。

修改    protectedmodulessrbaccontrollersAuthitemController.php 文件中的 actionShowAssignments 方法

源代码如下

  public function actionShowAssignments() {
    $userid = isset($_GET["id"]) ? $_GET["id"] :
      $_POST[Helper::findModule('srbac')->userclass][$this->module->userid];
    $user = $this->module->getUserModel()->findByPk($userid);
    $username = $user->{$this->module->username};
    $r = array(0 => array(0 => array()));
    if ($userid > 0) {
      $auth = Yii::app()->authManager;
      /* @var $auth CDbAuthManager */
      $ass = $auth->getAuthItems(2, $userid);
      $r = array();
      foreach ($ass as $i => $role) {
        $curRole = $role->name;
        $r[$i] = $curRole;
        $children = $auth->getItemChildren($curRole);
        $r[$i] = array();
        foreach ($children as $j => $task) {
          $curTask = $task->name;
          $r[$i][$j] = $curTask;
          $grandchildren = $auth->getItemChildren($curTask);
          $r[$i][$j] = array();
          foreach ($grandchildren as $k => $oper) {
            $curOper = $oper->name;
            $r[$i][$j][$k] = $curOper;
          }
        }
      }
      // Add always allowed opers
      $r["AlwaysAllowed"][""] = $this->module->getAlwaysAllowed();
      $this->renderPartial('userAssignments', array('data' => $r, 'username' => $username));
    }
  }

我们把第 7 行的判断语句修改下 if ($userid > 0) 

修改成 if (count($user)> 0) ,即可，修改后代码如下

  public function actionShowAssignments() {
    $userid = isset($_GET["id"]) ? $_GET["id"] :
      $_POST[Helper::findModule('srbac')->userclass][$this->module->userid];
    $user = $this->module->getUserModel()->findByPk($userid);
    $username = $user->{$this->module->username};
    $r = array(0 => array(0 => array()));
    if (count($user) > 0) {
      $auth = Yii::app()->authManager;
      /* @var $auth CDbAuthManager */
      $ass = $auth->getAuthItems(2, $userid);
      $r = array();
      foreach ($ass as $i => $role) {
        $curRole = $role->name;
        $r[$i] = $curRole;
        $children = $auth->getItemChildren($curRole);
        $r[$i] = array();
        foreach ($children as $j => $task) {
          $curTask = $task->name;
          $r[$i][$j] = $curTask;
          $grandchildren = $auth->getItemChildren($curTask);
          $r[$i][$j] = array();
          foreach ($grandchildren as $k => $oper) {
            $curOper = $oper->name;
            $r[$i][$j][$k] = $curOper;
          }
        }
      }
      // Add always allowed opers
      $r["AlwaysAllowed"][""] = $this->module->getAlwaysAllowed();
      $this->renderPartial('userAssignments', array('data' => $r, 'username' => $username));
    }
  }

修改后就能看到效果了，效果如下

如过不懂什么原因，可分析下源代码。
