I'm having problems with an empty cart button. What I want it to do when I click the button is to empty the cart, do a blind_up effect, and redirect me to the index page. It does all of this except redirect me to the index.

Here's the methods in the controller:

def empty_cart
  session[:cart] = nil
  @cart = find_cart
  redirect_to_index unless request.xhr?
end

private
def redirect_to_index(msg = nil)
   flash[:notice] = msg
   redirect_to :action => 'index'
end

Here's the button:

<% form_remote_tag :url => { :action => :empty_cart } do %>
  <%= submit_tag "Empty cart" %>
<% end %>

And the blind_up javascript:

page[:cart].visual_effect :blind_up

Could you please tell me why the redirect_to_index method doesn't work.

Thank you!

Your redirect_to_index method isn't working because at the end of your empty_cart method, you tell your code to redirect to index unless the request is coming via an XMLHttpRequest (which it is, because you used form_remote_tag, instead of form_tag). Try switching to just form_tag (or reading a little further in the book), and you should be able to make things work the way you want them to.
