Legato

There's rewritten and (moar) actively maintained version of the library in the form of Legato.
You might want to check it out as it's mostly compatible with Garb.

Important Changes

This fork contains heavily modified version of vigetlab's Garb library.
It works only with version 3 of Google API.

Please read CHANGELOG.

Description

Provides a Ruby API to the Google Analytics API.

https://developers.google.com/analytics/devguides/reporting/core/v3/coreDevguide

Basic Usage

Single User Login

> Garb::Session.api_key = api_key # required for 2-step authentication
> Garb::Session.login(username, password)

OAuth Access Token

> Garb::Session.access_token = access_token # an instance of OAuth2::Client

Accounts, WebProperties, Profiles, and Goals

> Garb::Management::Account.all
> Garb::Management::WebProperty.all
> Garb::Management::Profile.all
> Garb::Management::Goal.all

Profiles for a UA- Number (a WebProperty)

> profile = Garb::Management::Profile.all.detect {|p| p.web_property_id == 'UA-XXXXXXX-X'}

Define a Report Class

class Exits
  extend Garb::Model

  metrics :exits, :pageviews
  dimensions :page_path
end

Get the Results

> Exits.results(profile, :filters => {:page_path.eql => '/'})

OR shorthand

> profile.exits(:filters => {:page_path.eql => '/'})

Be forewarned, these numbers are for the last 30 days and may be slightly different from the numbers displayed in Google Analytics' dashboard for 1 month.

Other Parameters

• start_date: The date of the period you would like this report to start
• end_date: The date to end, inclusive
• limit: The maximum number of results to be returned
• offset: The starting index
• all: Return all results if true (which might result in several requests to GAPI)

Metrics & Dimensions

Metrics and Dimensions are very complex because of the ways in which they can and cannot be combined.

I suggest reading the google documentation to familiarize yourself with this.

https://developers.google.com/analytics/devguides/reporting/core/dimsmets#q=bouncerate

When you've returned, you can pass the appropriate combinations to Garb, as symbols.

Filtering

Google Analytics supports a significant number of filtering options.

https://developers.google.com/analytics/devguides/reporting/core/v3/reference#filters

Here is what we can do currently: (the operator is a method on a symbol for the appropriate metric or dimension)

Operators on metrics:

eql => '==',
not_eql => '!=',
gt => '>',
gte => '>=',
lt => '<',
lte => '<='

Operators on dimensions:

matches => '==',
does_not_match => '!=',
contains => '=~',
does_not_contain => '!~',
substring => '=@',
not_substring => '!@'

Given the previous Exits example report in shorthand, we can add an option for filter:

profile.exits(:filters => {:page_path.eql => '/extend/effectively-using-git-with-subversion/')

SSL

Version 0.2.3 includes support for real ssl encryption for SINGLE USER authentication. First do:

Garb::Session.login(username, password, :secure => true)

Next, be sure to download http://curl.haxx.se/ca/cacert.pem into your application somewhere. Then, point Garb.ca_cert_file property to that file.

For whatever reason, simply creating a new certificate store and setting the defaults would not validate the google ssl certificate as authentic.

OPEN / READ TIMEOUT

The open and read timeout values used with the network client (Net::HTTP) are configurable. Both values default to 60 seconds.

Garb.open_timeout = 3
Garb.read_timeout = 3

TODOS

• rebuild AND/OR filtering in Garb::Model

Requirements

• active_support >= 2.2
• multi_json >= 1.3

Requirements for Testing

• shoulda
• mocha
• bourne

`cd garb && rake install`

OR with bundler:
