i have simmilar question to this Laravel nova action - get current model instance on fields()

It is possible.

I use Laravel 7.x and nova 3.10

//need to load value of current model resource "size" to inform user

        })
        ->readonly(),

    Number::make(__('Amount'), 'amount')
        ->sortable()
        ->min(1) // -> i need to change this based on "size" form model resource
        ->max(9999)
        ->step(1) // -> i need to change this based on "size" form model resource
        ->updateRules('nullable')
        ->rules('required', 'number')
        ->help(__('in kilograms')),

How to load this JS array "ConfirmActionModal['selectedResources'][0]" in laravel fields?

I'm not well in JS, how to load values into php ?

Solution

  • get model name:

    $model = $request->viaResource;

    get model ID:

    $id = $request->viaResourceId;

    example:

    $post = $parent = \App\Models\Post::find($request->viaResourceId);
