# 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];
}
//...
```
