Laravel Nova - Save multiple rows to database on create

Question

I'm converting a Laravel app that was using Backpack across to Laravel Nova.

One of my models Images allows the user to add multiple images with a base set of information from the initial form. The form in this instance asks how many images are in the series via a dropdown and then has a number of relevant fields that will be used for all of the new images being added. When saving, in the controller, I'm using the following eloquent feature to run a number of tasks and insert the required number of rows:

public function store(StoreRequest $request){
  //Get some info
  //Make some tweaks
  //Use for loop to save multiple records
  for ($k = 0; $k < $addim; $k++){
    //Do some stuff      
    parent::storeCrud(${"request"});
  }
}

This works perfectly and inserts however many records are required.

In Laravel Nova, I can't see a way to use this same approach. Using an event listener in the model doesn't seem like the right way to save multiple records and I can't find any reference to a controller function I can use to achieve this.

I would really appreciate some thoughts and guidance on the best way to complete this part.

If someone has stumbled upon this type of problem.

You can use Laravel Observers.

In order to restrict the event to be fired only when resource is created and only using nova you can declare Observer in NovaServiceProvider.php as follows

/**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        parent::boot();
        Nova::serving(function () {
            Image::observe(ImageObserver::class);
        });
    }

Above code will only be triggered when your image object is modified using nova system only.

For ref Observer code will look like following

<?php

namespace App\Observers;

use App\Models\Document;

class ImageObserver
{
    /**
     * Handle the Image "created" event.
     *
     * @param  \App\Models\Image  $image
     * @return void
     */
    public function created(Image $image)
    {
        //logic to create multiple records
    }

    
}
