Fork of the standard auto_complete plugin to support: 1. Creating auto complete text fields that can be repeated more than once a single form. 2. Using auto_complete_for with named scopes to display a customized list of autocomplete options. See: http://patshaughnessy.net/repeated_auto_complete for details. Repeated autocomplete text fields: ================================== A "text_field_with_auto_complete" method is made available to form_for and fields_for that: - Insures unique id's for <input> and <div> tags - Uses the object name from the surrounding call to form_for or fields_for so attribute mass assignment will work as usual - Works with the same server side controller method, auto_complete_for, as usual Example: <% for person in @group.people %> <% auto_complete_fields_for "group[person_attributes][]", person do |person_form| %> <p> Person <%= person_form.label :name %><br/> <%= person_form.text_field_with_auto_complete :person, :name, {}, {:method => :get } %> </p> <% end %> <% end %> Named scopes with auto_complete_for: ==================================== auto_complete_for now optionally accepts a block that is called with the item list and HTTP parameters when the auto complete AJAX request is received. This block can be used to specify that a named scope be used to generate a customized list of autocomplete options. Example using anonymous scope: auto_complete_for :some_model, :some_other_field do |items, params| items.scoped( { :conditions => [ "a_third_field = ?", params['some_model']['a_third_field'] ] }) end Example using named scope: class Task < ActiveRecord::Base belongs_to :project named_scope :by_project, lambda { |project_name| { :include => :project, :conditions => [ "projects.name = ?", project_name ] } } end auto_complete_for :task, :name do | items, params | items.by_project(params['project']) end Copyright (c) 2009 [Pat Shaughnessy], released under the MIT license
