admin模块的新闻控制器代码：

<?php
namespace app\admin\controller;
use app\admin\controller\Common;
use app\admin\model\NewsModel;
use think\facade\Request;
use think\facade\Session;
class News extends Common
{
    public function index(NewsModel $news)
    {
    	$new=$news->order('time','desc')->paginate(8);
    	//渲染新闻列表
        $page = $new->render();
    	$count = $new->count(1);
    	$this->view->new = $new;
    	$this->view->count = $count;
    	$this->view->page = $page;
        return $this->fetch();
    }
    public function add()
    {
    	//添加新闻
        return $this->fetch();
    }
    public function DoAdd(NewsModel $news){
        $data=Request::param();
        $data['time']=time();
        $data['username']=Session::get('username');
        $title=$data['title'];
        $res=NewsModel::where('title',$title)->find();
        if ($res) {
        	return ['res'=>0,'msg'=>'新闻标题重复！'];
        }
        if($news->save($data)){

        	return ['res'=>0,'msg'=>'发布失败！'];

        }
    }
    public function upload(){

    	if ($info=$file->validate(['ext'=>'jpg,jpeg,png,gif'])->move('upload')) {
    		return json(['errno'=>0,'data'=>['/upload/'.$info->getSaveName()]]);
    	}else{
    		return $file->getError();
    	}
    }
    public function edit(NewsModel $news)
    {

        }
    }

}
?>

3.新闻模型代码：

<?php
namespace app\admin\model;
use think\Model;

class NewsModel extends Model
{
	protected $table="news";
	//设置主键
	protected $key="id";
}
?>

    </div>
    <script>
      layui.use('laydate', function(){
