tp 模型Model 获取器

获取器的作用是在获取数据的字段值后自动进行处理，例如，我们需要对状态值进行转换

模型文件Team.php

namespace app\index\model;

use \think\Model;
use \think\Db;
class Team extends Model
{
    //带下划线的去掉下划线  如原属性dept_id
    public function getdeptIdAttr($value)
    {
        $dept=db('dept')->select();
        $status=[];
        foreach ($dept as $k => $v) {
            $status[$v['id']]=$v['name'];
        }
    // 　　$status = [-1=>'删除',0=>'禁用',1=>'正常',2=>'待审核'];
        return $status[$value];
    }
}

控制器页Team.php

namespace app\index\controller;

use \think\Controller;
use think\Db;
use app\index\model\Team as teamModel;


class Team extends Controller
{
    public function index()
    {
        $model = new teamModel();// 第一条数据
        $first_id=db('team')->where('id > 0')->min('id');
        $first=$model->where('id',$first_id)->find();
        $this->assign("first",$first);
        return $this->fetch();
    }
