Google Shutting Down Deprecated Auth on April 20th, 2015
On April 20th, Google will be shutting down ClientLogin, AuthSub, and OAuth 1.0. https://groups.google.com/forum/#!topic/google-analytics-api-notify/g8wbdUqEDd0
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)
-
sampling_level: Specify precision vs speed strategy (
default
,faster
,greater_precision
)
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 https://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
Install
Add this line to your application’s Gemfile:
gem 'garb'
Then run:
bundle install
