Rails change routing of submit in form_for

Question

I have a model 'Article' and a model 'Ratings' nested within articles.

/articles/123/ratings

I want to change the routing of the f.submit in ratings/_form.html.erb now it is so, that after pressing submit, my application routs to

/ratings/111

but I want to route it to

/article/123

How can I change the routing in a form_for f.submit button. I have found here something like this:

<% form_for :thing, :url => 
 url_for(:action => "update", :id => @thing) do |f| %>

But this do not work for my rails 3.2. Thanks for your help,

:url - The URL the form is submitted to. It takes the same fields you pass to url_for or link_to. In particular you may pass here a named route directly as well. Defaults to the current action.

<% form_for :thing, :url => {:action => "update", :id => @thing} do |f| %>

you can also pass it the path_name by using the helper. so you can also do something like

:url => update_article_path(@article)
