Ho to "create" a field in a queryset to show in my template?

Hello,

I have these view:

def planos_view(request, cat_id=0):
    if cat_id == '0':
        categorias = Categoria.objects.filter(publicado=True)
    else:
        categorias = Categoria.objects.filter(publicado=True).filter(id=cat_id)

    for c in categorias:
        c.total = Plano.objects.filter(categoria=c).count()

    return render_to_response('planos.html', locals(),
                              context_instance=RequestContext(request))

I want to add the "total" field in my "categories" model.. What's the best approach for these, because these code above don't work...

Thanks agains 

T.·.F.·.A.·.     S+F
