JQuery autocomplete example

I was trying to follow along on the github example (GitHub - crowdint/rails3-jquery-autocomplete: An easy and unobtrusive way to use jQuery's autocomplete with Rails 3) for building an autocomplete and ran into a small set of problems. I'm not using the exact names of models, but I suppose I could. It's just a dummy set. For me: Model is Package and attribute is Brand.

I don't understand what the reference to class ProductsController < Admin::BaseController has to do with anything relevant. Typically Controllers inherit from ApplicationController. Why this is different it not explained.

but once I get past this... I just did it anyways.

It doesn't do anything. There's no callbacks to the server, no database lookups, and no visible behavior.

My form looks like: <form accept-charset="UTF-8" action="/packages/1" class="edit_package" id="edit_package_1" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="ob80tvhunNJs2IAL1qiLdppBRNLq6hSRKASZo4f+Cr4=" /></div>   <input data-autocomplete="/packages/autocomplete_package_brand" id="package_brand" name="package[brand]" size="30" type="text" value="Puppy Chow" /> </form>

with a code reference of:

VIEW <%= form_for @package do |f| %>   <%= f.autocomplete_field :brand, autocomplete_package_brand_packages_path %> <% end %>


CONTROLLER   autocomplete :package, :brand

Hate to do this but, "What am I doing wrong?" or "Where can I check next?" I've tried looking for more information on examples and/or use in Rails 3 but it's pretty lacking. I do hope I can get some help with this - I'm under the impression that JQuery is a bit more active and promoted than prototype and scriptalicious.

Hey did you fixed the same? I too have same issues...
