RailsAutocomplete

A hassle-free autocomplete for Rails 3.2 using Twitter bootstrap.

Installation

Add this line to your application's Gemfile:

gem 'rails_autocomplete'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_autocomplete

Then you need to add the following line to your application.js:

//= require rails_autocomplete

Usage

Assuming you have a Post model where you want to autocomplete posts based on their title field:

Add the following to app/views/posts/_form.html.erb:

<%= f.autocomplete_field :post, autocomplete_posts_path %>

app/controllers/posts_controller.rb:

def autocomplete
  @posts = Post.autocomplete(:name, params[:q])
  respond_to do |format|
    format.json { render json: @posts }
  end
end

Triggers

When a text field is autocompleted, it triggers an autocomplete event, it also passes the data that has been autocompleted, both id and value

$("#input").on("autocomplete", function(event, data){
    console.log("Autocompleted id is " + data.id);
    console.log("Autocompleted value is "+ data.value);
});
