Search duplicate items with the function morphToMany in Laravel

Question

I want to create a routine function in my project. I've created it in Laravel 10 with Alpine, Tailwind, Livewire and Flowbite.

enter image description here

Which Laravel object do I use for this?

Thank you for the reply and have a nice day. Viviane Le Hegaret

Please edit your question and include your code as properly formatted text. Images are not helpful for code debugging, as we cannot copy and paste (or otherwise manipulate) your code if it's an image... — Tim Lewis

I would like a standard function! The images I posted are more to show the function names! I didn't code anything more than the model class and a line where to put the future function. — Viviane Le Hegaret

what is a "routine function"? "I've created it in laravel 10 with alpine tailwind,livewire and flowbite" - you have created all of that in your screenshot but don't know how to add a function? — kris gjika

in my function, there is $object->libraries()-><!< What am I writing here? > to search and delete duplicate items in my database by object — Viviane Le Hegaret

I found it! You had to add a condition to tell it that if it finds 2 or more identical objects, you have to delete the relationship and recreate one.

I'm closing the discussion. Have a nice day.

public function updateUser($object){
        $userToChange=$object->users()->first();
        if (empty($userToChange)) {
            $object->users()->save(User::where('id',Auth::user()->getAuthIdentifier())->first());
        }elseif($object->users()->where('user_id', $userToChange->id)->count() >= 1){ //add condition to detect if several identical objects exists
            $object->users()->detach($userToChange->id);
            $object->users()->save(User::where('id',Auth::user()->getAuthIdentifier())->first());
        }else {
            if(Auth::user()->getAuthIdentifier()!=$userToChange->id){
                $object->users()->sync(User::where('id',Auth::user()->getAuthIdentifier())->first());
            }
        }
    }
