    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        slug_url = self.kwargs['slug']

Answer 1

product = Product.objects.filter(slug=slug_url)

This return a queryset, not an object so you cannot access object field like this. Either use .first() to get an object or if you want to update all objects in queryset, then use

product.update(view_count = F('view_count') + 1)
