Question

我正在练习yii1.1。我有两个具有相同功能的模型，如何将它们合并？

class Issue extends TrackStarActiveRecord
...
{
public function getUserText($user_id=null)
    {
        $sql="SELECT username FROM tbl_user WHERE id= $user_id";
        $command = Yii::app()->db->createCommand($sql);
        $username = $command->queryAll();
        return $username;
    }
}


class Project extends TrackStarActiveRecord
{
...
public function getUserText($user_id=null)
    {
        $sql="SELECT username FROM tbl_user WHERE id= $user_id";
        $command = Yii::app()->db->createCommand($sql);
        $username = $command->queryAll();
        return $username;
    }
}

我想从两个不同的视图调用getUserText（）函数，但是我不想在两个不同的模型中编写相同的函数。所以我需要合并它们。

复制代码并在未描述用户的类中获取用户名不是一个好主意。您可以将方法放在用户类中：

public $id;    
public function getUserText()
        {
            $sql="SELECT username FROM tbl_user WHERE id= $this->id";
            $command = Yii::app()->db->createCommand($sql);
            $username = $command->queryAll();
            return $username;
        }
    }

并执行它：

$user = new User();
$user->id = 55;
$username = $user->getUserText(); // better call it getName()

另一种方法是使用ActiveRecord，请参阅有关它的Yii文档

您可以在用户模型中创建静态方法：

class User extends CActiveRecord {

    public static function getUserText($id)
    {
        $sql = "SELECT username FROM tbl_user WHERE id= :id";
        $command = Yii::app()->db->createCommand($sql);
        return $command->queryAll(true, array(':id' => $id));
    }
}

// and call it
$username = User::getUserText(5);

如何从另一个模型调用函数？
