Auto_complete_for question - ruby-on-rails

Question

I've recently installed this plugin, and I meant to create a Tag field with it, like StackOverFlow does.
When I put the following syntax on my AnnouncementsController(I want to tag announcements) it works great:
auto_complete_for :announcement, :title
protect_from_forgery :only => [:create, :delete, :update]
Also, I had to add the routes syntax as well to make it work:
map.resources :announcements, :collection => {:auto_complete_for_announcement_title => :get }
Now, when I try to accomplish the same with the tags, at the time I create a new announcement, I simply replace the word "announcement" for "tag" and "title" for "name", and it won't work. Tag makes reference for my Tags table at the database.
The error says the following:
<h1> ActiveRecord::RecordNotFound
in AnnouncementsController#show </h1>
<pre>Couldn't find Announcement with ID=auto_complete_for_tag_name</pre>
Can anybody tell me what I'm doing wrong?
Thanks,
Brian

Answer 1

In your view you probably want to change:
<%= text_field_with_auto_complete :announcement, :title %>
to:
<%= text_field_with_auto_complete :tag, :name %>
to make it work, take another look at the error it's giving, it's still calling announcement.
--- edit:
from autocomplete source:
def text_field_with_auto_complete(object, method, tag_options = {}, completion_options = {})

Answer 2

Well, I finally got the answer to my problem.
I was missing the following at routes.rb:
map.auto_complete '/:controller/:action',
:requirements => { :action => /auto_complete_for_\S+/ },
:conditions => { :method => :get }
My new question now it works is the following:
What if I wanted to multi-tag an announcements, for example: "Ruby, C#". Should I change the plugin's logic or is there a functionality to make this work? Cause right now, it will check for the text_field text, not discriminating a new word after a comma or any kind of separator.
Thanks,
