rails autocomplete tags separated by commas using regex

Question

I am using the old auto_complete plugin in conjunction with the acts as taggable on gem in an attempt to basically replicate the tagging behavior of Stack Overflow itself! I am

Answer 1

I know this is old, but to recreate this behavior I used rails3-jquery-autocomplete with acts-as-taggable-on. They work very nicely and easily together.

// Model
class Foo < ActiveRecord::Base
  acts_as_taggable_on :tags
end

// Controller
class FoosController < ApplicationController
  autocomplete :tag, :name, :class_name => 'ActsAsTaggableOn::Tag'
  ...
end

// Routes
resources :foos do
  collection do
    get :autocomplete_tag_name
  end
end

//View
<% form_for :foo do |form| %>
  <%= form.label :tag_list, "Tags" %>
  <%= form.autocomplete_field :tag_list, autocomplete_tag_name_foos_path, :"data-delimiter" => ', ' %>
<% end %>

Hope that helps someone.
