+# Observers
+
+Observers maybe used for creating and clearing cache purposes
+
+## Example observer use
+
+Create you own class with observer:
+
+```php
+<?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;
+    }
+}
+```
+
+Use in models:
+
+```php
+<?php namespace Dimti\Mirsporta\Models;
+
+use Dimti\Mirsporta\Classes\Observers;
+
+class Tag extends Model
+{
+    //...
+
+    public function afterSave()
+    {
+        Observers\TagObserver::clearCache();
+    }
+    
+    //...
+}
+```
+
+And in your code for caching data based on this model/observer:
+
+```php
+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 - that is simple helper for concatenate array elements to string
+
+## Clearing cache from admin dashboard widget
+
+### Template
+
+```html
+<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;"
+/>
+```
+
+### Controller widget action
+
+```php
+use Dimti\Mirsporta\Classes\Observers;
+
+//...
+
+public function onClearTagCache()
+{
+    Observers\TagObserver::clearCache();
+
+    return ['status' => 1];
+}
+
+//...
+```
