Question

Here we go in my situation I have videos and video_tags table and it has a relationship one to many because in a video has many tags. I'm trying to achieve to delete record1 and record2 storing in different table using relationship in one query only then the records will be deleted from table1 and table2. I think it is possible in laravel please i need help.

Model:

    protected $guarded = ['id'];

    public function tags()
    {
        return $this->hasMany('App\VideoTag');
    }
}

Controller:

public function postDeleteVideo(Request $request, $id){
        $tag = Video::find($id)->tags->delete();// <-- problem here
        return response()->json(array('success'=>true));
    }

What you need is to set CASCADE relationships in your database.

Then...

$video = \\Video::find(1);

$video->delete();
