Laravel 隐藏属性.例如密码 安全

According to http://laravel.com/docs/eloquent, one can Hide Attributes From Array Or JSON Conversion by using a protected $hidden variable in the Model.

class User extends Eloquent {
    protected $hidden = array('password');
}

Great, however when running print_r(User::all()) the encrypted password is sent from server to client inside the User object.

这不仅限于print_r()，如果查询特定用户，$user->password将在视图中显示加密的密码.

Is there a way of stopping this? Every time my user object is queried, the password will sent with it as part of the data, even though it doesn't need to be.
