在 Laravel 6 中，遍历 模型对象 时，赋值属性后，未更新
1、打印当前对象，其属性 [architecture] => 2.0 。如图1

1 2 3 4 5 6 7 | $wpTheme->architecture = '2.0';print_r($wpTheme);echo "\n";echo $wpTheme->architecture;exit;unset($wpTheme->themeInstallation);$themes[] = $wpTheme; |
3、打印对象 $wpTheme，其属性 [architecture] => 2.0。打印 $wpTheme->architecture，其值为 1.0。不符合预期。如图2

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | protected $appends = [ 'created_at', 'updated_at', 'cover_url', 'alias', 'architecture', 'is_fission',];/** * 获取主题架构版本, 默认为1.0 * * @return void */public function getArchitectureAttribute(){ $config = config('theme.' . $this->alias); return isset($config['architecture']) ? $config['architecture']: '1.0';} |
5、最终决定在查询列表时，使用 ->toArray() 方法，然后遍历时，$wpTheme 已经为数组。如图3

6、代码实现如下
1 2 3 | $wpTheme['architecture'] = '2.0';unset($wpTheme['theme_installation']);$themes[] = $wpTheme; |
7、查看响应结果，符合预期。如图4
