来由：

数据库的这个字段我想返回成：

新奇的写法如下：

逻辑层的代码：

  public function goodsDetail($goodId)
    {
        $detail = $this->good->where('id', $goodId)->hidden(['type_params','user_id'])->find();
        if (!$detail) {
            return $this->fail("获取数据失败!");
        }
        if ($detail->type === 1) {

            //特殊的写法
            $detail->award_lists = '';
        } else if ($detail->type === 2) {
            $number_group_buyer = Order::where('good_id', $goodId)->where('status',1)->count('id');
            $detail->number_group_buyers = $number_group_buyer;
        }

        return $this->success("获取数据成功", $detail);

    }

模型层的代码：

<?php

namespace app\daogou\model;

use app\common\model\TimeModel;

class Goods extends TimeModel
{
    protected $table = 'dg_goods';

    protected $type = [
        'type_params'=>'json',
    ];



    //type_params:
    //      type = 1 : [['coin_id'=>1,'award'=>"0.80000000"],……]
    //      type = 2 : ['max_number'=>10,'winner'=>1]
    //      type = 3 : null

    public function user()
    {
        return $this->hasOne('user','user_id','id')->bind(['username']);
    }

    public function getStatusTxtAttr($v,$data)
    {
        //状态(-1:下架,1:上架,2:交易中)
        $status = [-1=>"下架",1=>"上架",2=>"交易中"];
        if(array_key_exists('status',$data)){
            return array_key_exists($data['status'],$status) ? $status[$data['status']] : $data['status'];
        }
        return '';
    }


    public function getPriceAttr($v)
    {
        return delZero($v);
    }
    public function getTypeTxtAttr($v,$data){
        //(1:奖购2:团购,3:闪购)
        $status = [1=>"奖购",2=>"团购",3=>"闪购"];
        if(array_key_exists('type',$data)){
            return array_key_exists($data['type'],$status) ? $status[$data['type']] : $data['type'];
        }
        return '';
    }




// 不理解的代码
    public function getAwardListsAttr($v, $good)
    {
        $awardLists = [];
        if ($good['type'] === 1) {
            $type_params = json_decode($good['type_params'],true);
            foreach ($type_params as $propertyId => $properNumber) {
                $propertyName = Coin::where('id', $propertyId)->value('name');
                $award['asset_name'] = $propertyName;
                $award['asset_number'] = $properNumber;
                array_push($awardLists,$award);
            }
        }
        return $awardLists;
    }



}

可以通过  ：

$ba = debug_backtrace();
var_dump($ba);
die();

来查看执行的流程，，流程如下（个人感觉看起来 【展示的效果】 不是很友好 很乱的感觉 ）：
