+
+namespace App\Models;
+
+use Illuminate\Database\Eloquent\Model;
+use Waad\Observer\HasObserver;
+
+class Work extends Model
+{
+    use HasObserver;
+
+
+    ......
+}
+```
+
+&nbsp;
+
+- if use observer different name class used `$observer` property
+
+```php
+<?php
+
+namespace App\Models;
+
+use App\Observers\MyWorkObserver;
+use Illuminate\Database\Eloquent\Model;
+use Waad\Observer\HasObserver;
+
+class Work extends Model
+{
+    use HasObserver;
+
+    public static $observer = MyWorkObserver::class;
+}
+```
+
+&nbsp;
+
+- if use multi observer different names classes used `$observer` property
+
+```php
+<?php
+
+namespace App\Models;
+
+use App\Observers\MyWorkObserver;
+use App\Observers\OurWorkObserver;
+use Illuminate\Database\Eloquent\Model;
+use Waad\Observer\HasObserver;
+
+class Work extends Model
+{
+    use HasObserver;
+
+    public static $observer = [MyWorkObserver::class, OurWorkObserver::class];
+}
+```
+
+&nbsp;
+
+

+```php
+php artisan make:observer YourModelObserver --model=YourModel
+```
+

+```php
+<?php
+
+namespace App\Observers;
+
+use App\Models\Work;
+
+class WorkObserver
+{
+    
+    public function creating(Work $work)
+    {
+        // This function is called when a new model instance is being created.
+        $work->title = $work->title . ".....";
+    }
+
+    public function created(Work $work)
+    {
+        // This function is called after a new model instance is successfully 
+        // created and saved to the database.
+
+        $work->users()->attach([1,2]);
+    }
+
+    public function updating(Work $work)
+    {
+        // This function is called when an existing model instance is being updated.
+
+        $work->status_color = $work->status ? 'green' : 'red';
+    }
+
+    public function updated(Work $work)
+    {
+        // This function is called after an existing model instance is successfully 
+        // updated and saved to the database.
+
+        $work->users()->sync([1,3]);
+    }
+
+    public function saving(Work $work)
+    {
+        // This function is called when a model instance is being saved
+        // (either created or updated).
+
+        $work->title = $work->title . ".....";
+    }
+
+    public function saved(Work $work)
+    {
+        // This function is called after a model instance is successfully saved 
+        // (either created or updated).
+
+        $work->status_string = 'working';
+        $work->save();
+    }
+
+    public function deleting(Work $work)
+    {
+        // This function is called when an existing model instance is being deleted.
+
+        $work->users()->detach();
+    }
+
+    public function deleted(Work $work)
+    {
+        // This function is called after an existing model instance is successfully deleted 
+    }
+
+    public function restoring(Work $work)
+    {
+        // This function is called when a "soft-deleted" model instance is being restored.
+    }
+
+    public function restored(Work $work)
+    {
+        // This function is called after a "soft-deleted" model instance is successfully restored.
+    }
+
+    public function retrieved(Work $work)
+    {
+        // This function is called after a model instance is retrieved from the database.
+
+        $work->increment('views');
+    }
+}
