Answer 1

Try changing your view like this.

   def SubCategorySlugListAPIView(request, subcat_slug):
        subcategories = SubCategory.objects.all()
        subcategory = get_object_or_404(SubCategory, subcat_slug=subcat_slug)            
        productlist = Product.objects.filter(subcategory=subcategory)
        paginator = Paginator(productlist, 12)
        page_number = request.GET.get('page')
        product = paginator.get_page(page_number)
        template_name = 'mainpage/cat-products.html'
        context = {'product': product,
               'subcategories': subcategories, 'subcategory': subcategory}
        return render(request, template_name, context)

OR you can also do it in the template with this.

<h5>Showing Products  {{subcategory.prosubcat.all.count}}</h5>

EDIT: Here I can see you are using paginator so you can do it with this.

Showing products {{product.start_index}} - {{prodct.end_index}} of {{product.count}} results.

See the docs for more details on pagination.
