This package permit add a trait for use in Elocuents Models that deletes incascade the Polymorphic Relations (MorphOne,MorphMany orMorphToMany).

This package can be used in Laravel 5.5 or higher.

You can install the package via composer:

composer require cesargb/laravel-cascade-delete

Use the traitCesargb\Database\Support\CascadeDelete in your Elocuent Model and define de propertycascadeDeleteMorph whith one String or Array with your methods than define the Polymorphic Relations.

<?phpnamespaceApp;useApp\Tag;useApp\Image;useApp\Option;useIlluminate\Database\Eloquent\Model;useCesargb\Database\Support\CascadeDelete;class Videoextends Model{use CascadeDelete;protected$cascadeDeleteMorph = ['image','tags','options'];publicfunctionimage()    {return$this->morphOne(Image::class,'imageable');    }publicfunctionoptions()    {return$this->morphMany(Option::class,'optionable');    }publicfunctiontags()    {return$this->morphToMany(Tag::class,'taggable');    }}

Now you can delete anApp\Video record, and any associatedApp\Image,App\Options and pivot records forApp\Tag will be deleted.

If you bulk delete a model with morphological relationships, you will haveresidual data that has not been deleted.

To clean this waste you have the methoddeleteMorphResidual

Sample:

Video::query()->delete();$video =newVideo;$video->deleteMorphResidual();

You can use Artisan commandmorph:clean to remove all residuals data from allyour Moldes that used theCesargb\Database\Support\CascadeDelete trait.

php artisan morph:clean
