Is it possible to just merge new or existing values on a JSON field?

I have settings field with various settings, and would like to not remove old entries that are not available in a given form. e.g.

{"layout":{"is_restaurant":true}}

{"layout":{"is_restaurant":true}}

and

Forms\Components\Toggle::make('settings.is_valid')

Forms\Components\Toggle::make('settings.is_valid')

I would like to keep what is under "layout" but just add is_valid if it does not exist or update if it does, so the end json would look like:

{"layout":{"is_restaurant":true}, "is_valid":true}

{"layout":{"is_restaurant":true}, "is_valid":true}

so 'settings.layout.is_restaurant' nesting is unlimited

yeh but if I hit save the layout.is_restaurant is gone There might be many various settings stored on the column. I was wondering if there is a possibility to just merge and not completely overwrite.

ah right maybe use mutateDataBeforeSave()?

Yeh, this works. 🙂

    protected function mutateFormDataBeforeSave(array $data): array
    {
        $data['settings'] = array_merge($this->record->settings ?? [], $data['settings']);

        return $data;
    }

    protected function mutateFormDataBeforeSave(array $data): array
    {
        $data['settings'] = array_merge($this->record->settings ?? [], $data['settings']);

        return $data;
    }

oh it looks like this preserves old values too if you write like so

                Forms\Components\Section::make('Layout Settings')
                    ->statePath('settings')
                    ->schema([
                        Forms\Components\Toggle::make('layout.show_language_bar'),
                    ])->collapsible()

                Forms\Components\Section::make('Layout Settings')
                    ->statePath('settings')
                    ->schema([
                        Forms\Components\Toggle::make('layout.show_language_bar'),
                    ])->collapsible()

If statePath empty then it just saves what is in the schema. I am leaving this for future reference if someone will be looking for similar.
