Rails 3 autocomplete

I've some problem. Can anyone help me with my mistake? I'm using rails 3 autocomplete gem from https://github.com/mikeauclair/rails3-jquery-autocomplete and follow all instructions, but have error:

undefined method `autocomplete_user_nickname' for #<Message:0xa09374c>

My routes:

resources :messages do
   get :autocomplete_user_nickname, :on => :collection
end

MessagesController.rb:

autocomplete  :user, :nickname

My new.html.erb:

<% form_for @message, :url => user_messages_path(@user) do |f| %>
  <%= f.text_field :sender_id %>
  <%= f.autocomplete_field :autocomplete_user_nickname, autocomplete_user_nickname_messages_path %>
  <%= f.text_field :subject %>
  <%= f.text_area :body %>
  <%= submit_tag "Send" %>
<% end %>

What I am doing wrong? Thanks.

Actually the :id_element option is broken, and if you install from this github fork it will work

gem 'rails3-jquery-autocomplete', :git => 'git://github.com/juniorz/rails3-jquery-autocomplete.git'

I think much better you use autocomplete.git. It works in Rails 3. It's easy.

https://github.com/rails/auto_complete/pull/9

But if you to know to use the jquery gem, I ask to you to put your solution and where WE are making mistake.

Bye....

According to the Readme at the project you linked, your form field is not correct. You have:

<%= f.autocomplete_field :autocomplete_user_nickname, autocomplete_user_nickname_messages_path %>

The Readme says it should be:

<%= f.autocomplete_field :user_nickname, autocomplete_user_nickname_messages_path %>

[Edit]

Based on your comments, I assume you have something like the following:

class Message < ActiveRecord::Base
  belongs_to :user
end

class MessagesController
  def new
    @message = Message.new
  end
end

I think you should use something like the following for your view:

<%= form_for(@message) do |f| %>
  <%= f.hidden_field :user_id, :id => "real_user_id"
  To: <%= autocomplete_field_tag 'throwaway_user', '',
          autocomplete_user_nickname_messages_path,
          :size => 75, :id_element => '#real_user_id' %> <br />
  Subject: <%= f.text_field :subject %>
  etc...
<% end %>

This way, the autocomplete field is just some throwaway data, but when it autocompletes it'll update the value of the real user ID tag (with the ID real_user_id) to be the ID of the autocompleted user.

[Another Edit]

Since I wasn't sure what the problem was after your last comment, I decided to make a small app myself. It seems to be working fine for me, so I assume there's something up with your model.

You can see what I did to implement this at this GitHub compare view; I left out the boring stuff, like installing jQuery and jQuery UI. You can see the app actually working in the screenshots in the readme. Hope this helps.
