Description
I am using Model Resource with Pages, there are "config", "app_id", "app_secret" fields, which "config" set hidden, I want to combine "app_id" & "app_secret" to json and save to config field.
ps. table doesn't have "app_id" & "app_secret" fields.

UI\Fields\Enum::make('platform_type')
    ->attach(Enums\PlatformType::class),
UI\Fields\Hidden::make('config'),
UI\Fields\Text::make('app_id'),
UI\Fields\Text::make('app_secret'),

If you just need to withdraw, you can use the Preview field.

Preview::make('App id', formatted: fn() => config('app_id'))

no, I want to save the app_id and app_secret data into tbl_platforms.config as
['app_id' => '324refEQi9', 'app_secret' => 'FDSA2huFU234FF']

[lee-to]

use onApply method! Example - https://moonshine-laravel.com/en/docs/3.x/recipes/change-field-logic

How can I combine multiple fields and save into one table field?

UI\Fields\StackFields::make('config')
  ->fields([
      UI\Fields\Text::make('config')
          ->translatable($this->tranlations . 'fields')
          ->virtualColumn('app_id')
          ->onApply(function (Model $item, $value) {
              $item->config = array_merge($item->config, ['app_id' => $value]);
          }),
      UI\Fields\Password::make('config')
          ->translatable($this->tranlations . 'fields')
          ->virtualColumn('app_secret')
          ->onApply(function (Model $item, $value) {
              $item->config = array_merge($item->config, ['app_secret' => $value]);
          }),
      UI\Fields\Text::make('config')
          ->translatable($this->tranlations . 'fields')
          ->virtualColumn('token')
          ->onApply(function (Model $item, $value) {
              $item->config = array_merge($item->config, ['token' => $value]);
          }),
      UI\Fields\Text::make('config')
          ->translatable($this->tranlations . 'fields')
          ->virtualColumn('aes_key')
          ->onApply(function (Model $item, $value) {
              $item->config = array_merge($item->config, ['aes_key' => $value]);
          }),
  ])
  ->translatable($this->tranlations . 'fields'),

Its shown array_merge(): Argument #1 must be of type array, null given

$item->config ?? []

I found a solution

overriding the save method in resource, place the logic "AFTER" $fields->withoutOutside() ...,

// ...
$fields->withoutOutside()
    ->each(fn (FieldContract $field): mixed => $field->apply($this->fieldApply($field), $item));

$data = request()->all();
$array = [
    'app_id' => $data['app_id'], 
    'app_secret' => $data['app_secret']
];
$item->config = $array;

if ($item->save()) {
// ...

tried the beforeCreating() and beforeUpdating() are not working because the $fields->withoutOutside() ... will rebuild the $item

StackFields for index, use Template

Template::make('Config', 'config')->fields([
                        Text::make('Language'),
                        Text::make('Cache'),
                    ])
                        ->changeFill(fn(mixed $data) => data_get($data, 'config'))
                        ->changeRender(fn(mixed $value, Template $ctx) => FieldsGroup::make($ctx->getPreparedFields())->fill($value))
                        ->onApply(function(mixed $item, mixed $value) {
                            $item->config = $value;
                            
                            return $item;
                        })
