I’ve forked the auto_complete plugin to support repeated text fields in a complex form; see http://patshaughnessy.net/repeated_auto_complete for more details.

If you had downloaded my plugin in the past, I’ve just made a couple of changes that will require some simple code changes to your app:

• You no longer need to or are able to use “auto_complete_form_for” or “auto_complete_fields_for.” I decided this was confusing and unnecessary. Now my plugin just mixes the text_field_with_auto_complete method right into the standard FormBuilder class. Just use form_for or fields_for as usual.
• I also dropped the object name parameter from text_field_with_auto_complete. Since text_field_with_auto_complete is a method of the form builder, the target object is indicated by the surrounding call to fields_for or form_for and so doesn’t need to be repeated. Now using form.text_field_with_auto_complete is very similar to using form.text_field or the other form builder methods: you just need to specify the column/field name.

So if you are using my old plugin with a Rails 2.2 or earlier app like this:

<% for person in @group.people %>
  <% auto_complete_fields_for "group[person_attributes][]", person do |form| %>
    Person <%= person_form.label :name %><br />
    <%= form.text_field_with_auto_complete :person, :name, {},
                                           {:method => :get}  %>
  <% end %>
<% end %>

… you should drop “auto_complete_” and “:person” and just use code like this instead:

<% for person in @group.people %>
  <% fields_for "group[person_attributes][]", person do |form| %>
    Person <%= person_form.label :name %><br />
    <%= form.text_field_with_auto_complete :name, {},
                                           {:method => :get}  %>
  <% end %>
<% end %>

And if you have Rails 2.3 or later and are using nested attributes, this would become:

<% form_for @group do |group_form| -%>
  <% group_form.fields_for :people do |person_form| %>
    Person <%= person_form.label :name %><br />
    <%= person_form.text_field_with_auto_complete :name, {},
          { :method => :get, :skip_style => true } %>
  <% end %>
<% end %>
