hi, i would like to change a partial in my view with the change of the item in a select_tag:

in the view:

<%= observe_field("payment_id", :url => {:controller =>'user_admins' ,:action => 'rend_part'},:on => 'change', :frequency => 0.1) %> <%= select( "payment", "id", { "Visa" => "1", "Mastercard" => "2"}) %>

in controller :

def rend_part

   if params[:payment]['id'] == '1'      render :partial => "patial_one"    else      render :partial => "patial_two"

   end end

def rend_part

  if params[:payment]['id'] == '1'     render :partial => "patial_one"   else     render :partial => "patial_two"

  end end

And what happens when you do this? Does it work? Have you got a function in place to update the page?

In long-hand Prototype.js code, this would look something like this:

$('my_picker').observe('change',function(evt){   new Ajax.Request('rend_part',{     parameters:{       payment_id:$F('my_picker')},       onSuccess:function(transport){         $('some_div').replace(transport.responseText);       }     }   }); });

How you go about doing this with the Ajax helpers is an exercise for the student...
