Rails - Jan 2008 - collection_select ajax.Updater InvalidAuthenticityToken

Hi,

I''m currently using the latest version of rails 2.0.2 with cookies.
My problem is as follows, to which I''ve not found any help on google
etc.

I have a page which presents the user with two drop-down menus.  The
first one, for example, asks for a car manufacurer, and the second,
which by default is blank, will ask for the model.  Within my view I
use the following

<%= collection_select(:manufacturer, :manufacturer_id,
@manufacturers, :id, :description, options ={:prompt => "-Select a
Manufacturer"},
           {
             :onChange => "new
Ajax.Updater(''manufacturer_model_id'', ''/
models/list_by_manufacturer_id/''+ this[this.selectedIndex].value,
{asynchronous:true, evalScripts:true})"
           }
         ) %>


<%= collection_select(:manufacturer, :model_id,
@models, :id, :description, options ={:prompt => "-Select a
model"})%>

The above works fine.  When I choose a manufacturer from the first
selection it fires the js but rails then returns an error:

  ActionController::InvalidAuthenticityToken
    in ModelController#list_by_manufacturer_id


I believe the problem might be because I need to pass the
authenticity_token as part of the request, though I''m not sure, and if
so I''m uncertain as to how I go about passing it within the ajax call.

Any help/direction would be greatly appreciated

seems i might be getting a little closer with the following code


<%= collection_select(:manufacturer, :manufacturer_id,
@manufacturers, :id, :description, options ={:prompt => "-Select a
Manufacturer"},
           {
             :onChange =>
link_to_remote("",:update=>"manufacturer_model_id'',:url=>{:controller=>:models,
:action=>:list_by_manufacturer_id})
           }


         ) %>


This seems to create the HTML etc correctly with the
authenticity_token, but when I click on the select list nothing is
every fired - no ajax call is ever made.

Any ideas?

dispite hoping to use link_to_remote I''ve ended up manually typing the
following;

<%= collection_select(:manufacturer, :manufacturer_id,
@manufacturers, :id, :description, options ={:prompt => "-Select a
Manufacturer"},
           {
:onChange =>
               "new Ajax.Updater
               (''member_id_selection'',
                ''/models/list_by_manufacturer_id/''+
this[this.selectedIndex].value,
                {asynchronous:true, evalScripts:true,
                parameters:''authenticity_token=''+
encodeURIComponent(''"+form_authenticity_token.to_s+"'')}
               )"
         ) %>


This actually works but seems but surely the helper method should have
worked.  Does anyone knoe whether I could redo this in a far cleaner
way, i.e. using a helper?

thanks

link_to_remote actually creates an <a> with an onclick that does the  
ajaxy stuff. In this sort of situation you want to use remote_function  
(takes basically the same arguments as link_to_remote, barring of  
course the first one)

The code in question would lie in the view rather than the
controller.  Stealing blindly from what was posted above:

<%= collection_select(:manufacturer, :manufacturer_id,
  @manufacturers, :id, :description,
  {:prompt => "-Select a Manufacturer"},
  { :onChange =>
remote_function(:url=>..., :method=>...,
:with=>"manufacturer_id")}
  ) %>
