PHP如下：
<?php
namespace app\index\controller;
use think\Controller;
use app\common\model\Paper as SPaper;
use think\Request;

class Paper extends Controller
{
public function index()
{
$pageSize = 2;
$Paper = new SPaper;
$paper = $Paper->paginate($pageSize);
$page = $Paper->render();
$this->assign('Paper',$paper);
$this->assign('page',$page);
$htmls = $this->fetch();
//返回给模板
return $htmls;
}

}


调用分类HTML：{$page}

提示错误信息：method not exist:think\db\Query->render
