Laravel on delete objects call model event - deleted - php

Question

Im trying to call model event - deleted. When Im deleting a video, I also want delete all comments which are associated with video, that is working fine. But I have also feeds table and when Im deleting video I want also delete all comments and comments feeds. Now when Im deleting video, I delete - video, video comments, video feed, but I need delete also video comment feeds.
The question is how I can make it possible to delete also comments feeds when Im deleting video?
Check VideoController.php destroy function
Video.php - Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Cviebrock\EloquentSluggable\Sluggable;
class Video extends Model
{
protected $table = 'videos';
public $timestamps = false;
use Sluggable, RecordsFeed;
public static function boot()
{
parent::boot();
}
public function sluggable()
{
return [
'slug' => [
'source' => 'title'
]
];
}
public function comments()
{
return $this->hasMany('App\VideoComment', 'videoid', 'id');
}
public function member()
{
return $this->belongsTo('App\Member', 'userid', 'member_id');
}
}
VideoComments.php - Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class VideoComment extends Model
{
protected $table = 'videos_comments';
public $timestamps = false;
protected $fillable = [
'text', 'userid', 'date'
];
use RecordsFeed;
public function videos() {
return $this->belongsTo('App\Video', 'id', 'videoid');
}
public function member() {
return $this->belongsTo('App\Member', 'userid', 'member_id');
}
}
RecordsFeed.php
<?php
namespace App;
use App\Libraries\Portal;
trait RecordsFeed
{
protected static function bootRecordsFeed() {
static::created(function($model) {
$model->recordFeed('created');
});
static::deleted(function($model) {
$model->deleteFeed('deleted');
});
}
public function feeds() {
return $this->morphMany( Feed::class, 'feedable' );
}
protected function recordFeed($event) {
$this->feeds()->create([
'user_id' => (new Portal)->getMemberID(),
'type' => $event.'_'.strtolower(class_basename($this))
]);
}
protected function deleteFeed($event) {
$this->feeds()->delete();
}
}
VideoController.php destroy function
public function destroy($id)
{
$video = Video::findOrFail($id);
$video->comments()->delete();
$video->delete();
Session::flash('success', 'Video deleted');
return redirect()->route('video.index');
}

Answer 1

Why do you not use on delete cascade at the creation of your table ?
In your migration, when you create your foreign key, just specify the on delete action like this :
$table->foreign('your_key')->references('id')->on('your_table')->onDelete('cascade');
It will automatically delete rows which are associated to the parent object.
You can find more details in Laravel documentation just here.

Answer 2

You don't have do anything code, you can set in database and set delete on cascade with relationshiop.
