There is no need to do filtering here, and definitely not on the Product model: this is a DetailView [Django-doc] for the Category model,s o you can work with:

class CategoryDetailView(DetailView):
    model = Category
    template_name = 'mainapp/product-category.html'
    context_object_name = 'category'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['categories'] = self.model.objects.all()
        context['products'] = Product.objects.all()
        context['category_products'] = self.object.product_set.all()
        return context

This will pass the Category for the given slug as category to the template, and the related Products as category_products.
