I''m working through Agile Web Dev. On page 130, you change an add to
cart button that posts to a new page to a button that does an Ajax
post. The code changes from button_to to form_remote_tag with
arguments.
But when I use that tag nothing appears on the page. (And there''s
nothing in the source. Rails just ignores the tag entirely.)
<% form_remote_tag :url => { :action => :add_to_cart, :id =>
product } do %>
<%= submit_tag "Add to Cart" %>
<% end %>
I''ve swapped my code for the code downloaded from the book, but still
nothing.
First, am I missing something? Second, how does one trouble-shoot
these kinds of problems? View source gives me nada and rails tells me
nothing. Where do I look to troubleshoot?
Thanks,

If you''re anything like me, a few times of leaving off the = sign as you have done here, and you''ll soon learn how to diagnose this particular problem! :) If you''re doing anything with Ajax and RJS, I can''t recommend the FireBug extension for Firefox enough. It''s a real godsend. Scott --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Where do I look to troubleshoot?You need Edge Rails to use the new-style form_tag and form_remote_tag helpers. If you''d rather not install via Subversion, I''ve prepared a zip file of today''s Edge rails. Download http://media.pragprog.com/titles/rails2/code.rails.zip into your application''s vendor/ directory, and then unzip it. Then go back to your applications main directory and type rake rails:update If you restart your application, all the new stuff should work. DON''T USE THIS IN PRODUCTION. NO WARRANTIES. ETC.

I updated to the most recent version of rails and that fixed it. (Though, I thought I was already on a recent enough edge.) And I guess that answers a troubl-shooting question: verify the feature you''re using against the rails version you''re using.
