Google API

A simple but powerful ruby API wrapper for Google's services.

Installation

Add this line to your application's Gemfile:

gem 'google-api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install google-api

Before Using this Gem

Google API depends on you to authenticate each user with Google via OAuth2. We don't really care how you get authenticated, but you must request access to a User's Google account and save the Refresh Token, Access Token, and Access Token Expiration Date.

As a starting point, we recommend using Omniauth for most authentication with Ruby. It is a great gem, and integrates seemlessly with most SSO sites, including Google. Check out the Wiki for more information.

Usage

This gem couldn't be easier to set up. Once you have a Client ID and Secret from Google (check out the Wiki for instructions on how to get these), you just need to add an initializer to your application that looks like this:

GoogleAPI.configure do |config|
  config.client_id = '[CLIENT ID]'
  config.client_secret = '[CLIENT SECRET]'
  config.encryption_key = '[ENCRYPTION KEY]'
end

We make it easy to set up an object as 'Google API Ready', giving you a couple of conveniences. For starters, if you have a User model, add the OAuth2 fields to your database migration:

create_table :users do |t|
  t.string :email_address, :first_name, :last_name
  t.oauthable
  t.timestamps
end

...and methods to the Model:

class User < ActiveRecord::Base

  oauthable

end

Once you have set that up, making a request to the Google API is as simple as:

user = User.find(1)
user.google.drive.files.list

This will fetch all files and folders in the user's Google Drive and return them in an array of hashes.

What Google APIs has this gem been tested against?
