Yii2 在layouts使用model数据

Question

这是layouts的main.php菜单列表，我怎么把数据库的数据传递到main.php.我知道有$this->params['params']="params",但是要使用beforeAction方法，还有其他简单方式吗

<div class="subNavBox">

            <div class="sBox">
                <div class="subNav sublist-down">
                    <span class="title-icon glyphicon glyphicon-chevron-right"></span>
                    <span class="sublist-title">资源管理</span>
                </div>
                <ul class="navContent" style="display:none">
