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 ):
