gmail-contacts's Introduction

gmail-contacts

A Ruby gem for getting a list of your Gmail contacts. Most of the code here has been extracted from mislav's contacts gem. It's been updated to work with Ruby 1.9 and Rails 3.

Installation

gem install gmail-contacts

or in your Gemfile:

gem 'gmail-contacts', :require => "gmail-contacts"

Usage

Get a link to the authorization URL:

GmailContacts::Google.authentication_url("http://mysite.com/invites")

The user will be redirected to the URL you pass and a token parameter will be sent along. Capture that token and then request the contacts:

GmailContacts::Google.new("some_token").contacts

Every Contact has a name and email fields:

GmailContacts::Google.new("some_token").contacts.each do |contact|
  puts "#{contact.name}: #{contact.email}"
end

Usage with Rails

First create the authorization link in one of your views:

# app/views/invites/new.html.erb
<%= link_to "Invite your Gmail contacts", GmailContacts::Google.authentication_url("http://mysite.com/invites") %>

Then create a controller action that receives the token and fetches the contacts:

# config/routes.rb
match "/invites" => "invites#index"

# app/controllers/invites_controller.rb
class InvitesController
  def index
    token = params[:token]
    @contacts = GmailContacts::Google.new("some_token").contacts
  end
end

Finally, iterate through the contacts in your view:

# app/views/invites/index.html.erb
<% @contacts.each do |contact| %>
  <span><strong><%= contact.name %></strong>: <% contact.email %></span>
<% end %>
