hyperf 數據庫模型-model操作

生成model

php bin/hyperf.php gen:model user

User model app/Model/User.php

<?php

declare (strict_types=1);
namespace App\Model;

use Hyperf\DbConnection\Model\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 = [];

    /**
     * 不自動維護時間戳
     * @var bool

模型查詢

use App\Model\User;

$user = User::query()->where('id', 1)->first();
$user = User::query()->where('id', 1)->find(1);
$freshUser = $user->fresh();

$count = User::query()->where('age', 23)->count();

插入

use App\Model\User;

$user = new User();
$user->name = 'xiaohong';
$user->age = 23;
$bool = $user->save();

更新

$user = User::query()->where('id', 1)->find(1);
$user->name = 'xiaohong';
$user->age = 23;
$bool = $user->save();

批量更新

User::query()->where('age', 23)->update(['age' => '24']);

刪除

User::query()->where('id', 3)->delete();
