数据库的表不完整，可以再上传一份数据库的表吗

因为不熟悉yii。所以我只好把所有log都打出来给您看了--！。我的环境是centos php7 nginx
在访问localhost/yii-master/frontend/web/index.php时的报错如下：

An Error occurred while handling another error:

呵呵，这个还不错啊！

安装后缺少表

请问在显示首页详细文章中actionDetail中，发表匿名评论的时候， 第一次是点击“发布”才可以发表评论成功，然后回到本页面，然后我F5刷新页面又会提交一次

 $postModel = new Comment();
        print_r(Yii::$app->request->post());
        if ($postModel->load(Yii::$app->request->post()))
        {
            $postModel->status=Comment::STATUS_PENDING;
            $postModel->post_id=$id;
            if ($postModel->save())
            {
                $this->added=1;
            }
         /*   $this->redirect(['post/detail', 'id'=>$id]);*/
        }

在一次提交评论后我打印post都有数据， 导致刷新页面都会提交评论（之前的评论）；如果我redirect就不会提交重复评论，但是added之类的就显示不出来了
请问怎么解决这个问题

if ($postModel->load($request->post()))
        {
            if(time() - $session->get('createComment') > 15 ) {
                $postModel->status = Comment::STATUS_PENDING;
                $postModel->post_id = $id;
                if ($postModel->save()) {
                    $this->added = 1;
                }
                $session->set('createComment', time());
                //$this->redirect(['post/detail', 'id'=>$id, 'added'=>$this->added]);
            }else{
                //时间不够
                
            }
        }
