观察者可用于创建和清除缓存

示例观察者使用

创建带有观察者的自己的类

<?php namespace Dimti\Mirsporta\Classes\Observers;

use Dimti\Mirsporta\Models;
use Wpstudio\Helpers\Classes\Observer\BaseObserver;

class TagObserver extends BaseObserver
{
    public static function getClass(): string
    {
        return Models\Tag::class;
    }
}

在模型中使用

<?php namespace Dimti\Mirsporta\Models;

use Dimti\Mirsporta\Classes\Observers;

class Tag extends Model
{
    //...

    public function afterSave()
    {
        Observers\TagObserver::clearCache();
    }
    
    //...
}

并在您的代码中使用，根据此模型/观察者缓存数据

use Dimti\Mirsporta\Classes\Observers;
//...

$cacheTags = Observers\TagObserver::getCacheTag();

$cacheKey = CacheManager::formatCacheKey([__CLASS__, __METHOD__, $siteId]);

\Cache::tags($cacheTags)->rememberForever($cacheKey, fn() =>
     Models\Tag::all()
));

• CacheManager::formatCacheKey - 这是一个简单的辅助函数，用于将数组元素连接成字符串

从管理仪表板小部件清除缓存

模板

<input
    type="button"
    class='btn btn-primary'
    value="Clear tag model cache"
    data-request="<?= $this->getEventHandler('onClearTagCache') ?>"
    data-request-success="$.oc.flashMsg({text: 'Cache of tag model is clearing', 'class': 'success', 'interval': 5}); return false;"
/>

控制器小部件动作

use Dimti\Mirsporta\Classes\Observers;

//...

public function onClearTagCache()
{
    Observers\TagObserver::clearCache();

    return ['status' => 1];
}

//...
