hyperf 数据库模型-修改器
本文主要是介绍hyperf 数据库模型-修改器，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
访问器
Index控制器 app/Controller/IndexController.php
<?php
namespace App\Controller;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\HttpServer\Annotation\AutoController;
use App\Model\User;
/**
* @AutoController();
*/
class IndexController
{
public function index(RequestInterface $request){
$id = (int)$request->input('id',1);
$user = User::query()->where('id',$id)->first();
return $user->name.PHP_EOL;
}
}
User模型 app/Model/User.php
<?php
declare (strict_types=1);
namespace App\Model;
use Hyperf\DbConnection\Model\Model;
class User extends Model
{
/**
* The table associated with the model.
*
* @var string
*/
protected $table = 'user';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [];
/**
* 访问器示例
* @param string $value
* @return string
*/
public function getNameAttribute($value)
{
return strtoupper($value);
}
}
user表数据
mysql> select * from user; +----+------------------+------+---------+---------+--------+ | id | name | age | role_id | address | status | +----+------------------+------+---------+---------+--------+ | 1 | xiaohong | 30 | 2 | NULL | 1 | | 2 | huyongjian2 | 24 | 2 | NULL | 0 | | 4 | xiaoming | 28 | 2 | NULL | 1 | | 5 | xiaoming5 | 30 | 2 | NULL | 1 | | 6 | huyongjian1 | 30 | 2 | NULL | 1 | | 7 | huyongjian2 | 31 | 2 | NULL | 1 | | 8 | xiaohong | 24 | 1 | NULL | 1 | | 11 | model_event_test | 20 | 1 | NULL | 1 | +----+------------------+------+---------+---------+--------+ 8 rows in set (0.00 sec)
测试访问(name变大写)
curl 118.195.173.53:9501/index/index?id=1
返回结果
XIAOMING
修改器
Index控制器 app/Controller/IndexController.php
<?php
namespace App\Controller;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\HttpServer\Annotation\AutoController;
use App\Model\User;
/**
* @AutoController();
*/
class IndexController
{
public function index(RequestInterface $request){
$id = (int)$request->input('id',1);
$user = User::query()->where('id',$id)->first();
$user->name = HUYONGJIAN;
$user->save();
return $user->name . PHP_EOL;
}
}
User模型 app/Model/User.php
<?php
declare (strict_types=1);
namespace App\Model;
use Hyperf\DbConnection\Model\Model;
class User extends Model
{
/**
* The table associated with the model.
*
* @var string
*/
protected $table = 'user';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [];
public $timestamps = false;
/**
* 修改器示例
*/
public function setNameAttribute($value){
$this->attributes['name'] = strtolower($value);
}
}
user表数据
mysql> select * from user; +----+------------------+------+---------+---------+--------+ | id | name | age | role_id | address | status | +----+------------------+------+---------+---------+--------+ | 1 | xiaohong | 30 | 2 | NULL | 1 | | 2 | huyongjian2 | 24 | 2 | NULL | 0 | | 4 | xiaoming | 28 | 2 | NULL | 1 | | 5 | xiaoming5 | 30 | 2 | NULL | 1 | | 6 | huyongjian1 | 30 | 2 | NULL | 1 | | 7 | huyongjian2 | 31 | 2 | NULL | 1 | | 8 | xiaohong | 24 | 1 | NULL | 1 | | 11 | model_event_test | 20 | 1 | NULL | 1 | +----+------------------+------+---------+---------+--------+ 8 rows in set (0.00 sec)
测试访问(name转变成小写，并保存)
curl 118.195.173.53:9501/index/index?id=1
返回
huyongjian
测试2
curl 118.195.173.53:9501/index/index?id=2
返回
huyongjian
再次查看user表数据，id=1,2的name都是小写
mysql> select * from user; +----+------------------+------+---------+---------+--------+ | id | name | age | role_id | address | status | +----+------------------+------+---------+---------+--------+ | 1 | huyongjian | 30 | 2 | NULL | 1 | | 2 | huyongjian | 24 | 2 | NULL | 0 | | 4 | xiaoming | 28 | 2 | NULL | 1 | | 5 | xiaoming5 | 30 | 2 | NULL | 1 | | 6 | huyongjian1 | 30 | 2 | NULL | 1 | | 7 | huyongjian2 | 31 | 2 | NULL | 1 | | 8 | xiaohong | 24 | 1 | NULL | 1 | | 11 | model_event_test | 20 | 1 | NULL | 1 | +----+------------------+------+---------+---------+--------+ 8 rows in set (0.00 sec)
日期转化器
控制器 app/Controller/IndexController.php
<?php
namespace App\Controller;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\HttpServer\Annotation\AutoController;
use App\Model\User;
/**
* @AutoController();
*/
class IndexController
{
public function index(RequestInterface $request){
$id = (int)$request->input('id',1);
$user = User::query()->where('id',$id)->first();
//time()返回时间戳(1633045072)
$user->date_time = time();
$user->save();
return [
'date_time' =>$user->date_time,
'time_stamp' => $user->date_time->getTimestamp()
];
}
}
User模型 app/Model/User.php
<?php
declare (strict_types=1);
namespace App\Model;
use Hyperf\DbConnection\Model\Model;
class User extends Model
{
/**
* The table associated with the model.
*
* @var string
*/
protected $table = 'user';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [];
public $timestamps = false;
/**
* 日期转换器字段配置
*
* @var array
*/
protected $dates = [
'date_time',
];
}
user表数据
mysql> select * from user; +----+------------------+------+---------+---------+---------------------+--------+ | id | name | age | role_id | address | date_time | status | +----+------------------+------+---------+---------+---------------------+--------+ | 1 | huyongjian | 30 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 2 | huyongjian | 24 | 2 | NULL | 2021-10-01 07:37:51 | 0 | | 4 | xiaoming | 28 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 5 | xiaoming5 | 30 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 6 | huyongjian1 | 30 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 7 | huyongjian2 | 31 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 8 | xiaohong | 24 | 1 | NULL | 2021-10-01 07:37:51 | 1 | | 11 | model_event_test | 20 | 1 | NULL | 2021-10-01 07:37:51 | 1 | +----+------------------+------+---------+---------+---------------------+--------+ 8 rows in set (0.00 sec)
访问测试
curl 118.195.173.53:9501/index/index?id=1
返回结果
{
"date_time": "2021-09-30T23:53:00.000000Z",
"time_stamp": 1633045980
}
更新后的user表数据(id=1记录date_time字段已自动转换成日期时间类型)
mysql> select * from user; +----+------------------+------+---------+---------+---------------------+--------+ | id | name | age | role_id | address | date_time | status | +----+------------------+------+---------+---------+---------------------+--------+ | 1 | huyongjian | 30 | 2 | NULL | 2021-10-01 07:53:00 | 1 | | 2 | huyongjian | 24 | 2 | NULL | 2021-10-01 07:37:51 | 0 | | 4 | xiaoming | 28 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 5 | xiaoming5 | 30 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 6 | huyongjian1 | 30 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 7 | huyongjian2 | 31 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 8 | xiaohong | 24 | 1 | NULL | 2021-10-01 07:37:51 | 1 | | 11 | model_event_test | 20 | 1 | NULL | 2021-10-01 07:37:51 | 1 | +----+------------------+------+---------+---------+---------------------+--------+ 8 rows in set (0.00 sec)
时间格式
控制器 app/Controller/IndexController.php
<?php
namespace App\Controller;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\HttpServer\Annotation\AutoController;
use App\Model\User;
/**
* @AutoController();
*/
class IndexController
{
public function index(RequestInterface $request){
$id = (int)$request->input('id',1);
$user = User::query()->where('id',$id)->first();
return [
'status' =>$user->status,
];
}
}
User模型 app/Model/User.php
<?php
declare (strict_types=1);
namespace App\Model;
use Hyperf\DbConnection\Model\Model;
class User extends Model
{
/**
* The table associated with the model.
*
* @var string
*/
protected $table = 'user';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [
'status'=>'boolean'
];
public $timestamps = false;
}
注：支持转换的数据类型有：integer, real, float, double, decimal:, string, boolean, object, array, collection, date, datetime 和 timestamp。 当需要转换为 decimal 类型时，你需要定义小数位的个数，如： decimal:2
user数据表
mysql> select * from user; +----+------------------+------+---------+---------+---------------------+--------+ | id | name | age | role_id | address | date_time | status | +----+------------------+------+---------+---------+---------------------+--------+ | 1 | huyongjian | 30 | 2 | NULL | 2021-10-01 07:53:00 | 1 | | 2 | huyongjian | 24 | 2 | NULL | 2021-10-01 07:37:51 | 0 | | 4 | xiaoming | 28 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 5 | xiaoming5 | 30 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 6 | huyongjian1 | 30 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 7 | huyongjian2 | 31 | 2 | NULL | 2021-10-01 07:37:51 | 1 | | 8 | xiaohong | 24 | 1 | NULL | 2021-10-01 07:37:51 | 1 | | 11 | model_event_test | 20 | 1 | NULL | 2021-10-01 07:37:51 | 1 | +----+------------------+------+---------+---------+---------------------+--------+ 8 rows in set (0.00 sec)
访问测试(status字段0或1会被转换false或true)
curl 118.195.173.53:9501/index/index?id=1
返回结果
{
"status": true
}
