What is the correct way to automatically pass in a form value (on the backend)?

I'm using this, which doesn't feel secure:

Forms\Components\Hidden::make('company_id')
  ->required()
  ->default(auth()->user()->company_id),

Forms\Components\Hidden::make('company_id')
  ->required()
  ->default(auth()->user()->company_id),

Should I be setting something at the model level? I did search the docs, but wasn't quite sure where to look to find this.

I guess it depends what you're doing with the value... what is it used for? If it's for saving the ID on the current record, a model observer is definitely better

@pboivin Thanks! I'll look into model observers. @Dennis Koch - Thanks a lot - that worked perfectly! Final code (much securer, and does away with the hidden field!):

protected function getActions(): array
    {
        return [
            Actions\CreateAction::make()
                ->disableCreateAnother(true)
                ->mutateFormDataUsing(function (array $data): array {
                    $data['company_id'] = auth()->user()->company_id;
                    return $data;
                }),
        ];
    }

protected function getActions(): array
    {
        return [
            Actions\CreateAction::make()
                ->disableCreateAnother(true)
                ->mutateFormDataUsing(function (array $data): array {
                    $data['company_id'] = auth()->user()->company_id;
                    return $data;
                }),
        ];
    }

That's a super useful function actually.
