Answer 1

You should change the related_name of product inside ProductBundle to something like bundles and then you can go product.bundles.all() to access all ProductBundle related to a Product

edit to filter all products if they have a ProductBundle

assuming you are using bundles as related_name: Product.objects.filter(bundles__isnull=False).distinct()
