question about render

Hi there, i have a question respect to the "render"

when use render in the controller

def create
    @contacto = Contacto.new(params[:contacto])
    respond_to do |format|
      if @contacto.save
        flash[:notice] = 'Su Consulta ha sido enviada'
        crear_correo(@contacto)
        format.html { redirect_to(:action => :new) }
      else
        format.html { render :controller => :contactos, :action => :new
}
      end
    end
  end

when the form have an error ,they should show error.. and do it.

but the url 'contactos/new' to 'contactos'

then if i use redirect_to ... the form don't show the errors

my question..how i do keep the url?

sorry for my language D=

thx for the help!

Why do you want to keep the same URL? As you noticed, you definitely
want to do a render, not a redirect. If you want to keep the /
contactos/new URL, then you'll need to break the Rails restful
conventions. By convention, a GET of /contactos/new will POST to /
contactos. You could change your routing to something like this:
map.connect "/contactos/new", :controller => "contactos", :action =>
"create", :conditions => {:method => :post}

However, I would try to use the convention unless you have a strong
reason for posting to /new.
