Connect to Google Contacts Data in Ruby


Connect to Google Contacts data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

The CData ODBC Driver for Google Contacts makes it easy to integrate connectivity to live Google Contacts data in Ruby. This article shows how to create a simple Ruby app that connects to Google Contacts data, executes a query, and displays the results.

Create an ODBC Connection to Google Contacts Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to Google Contacts Data

Create a new Ruby file (for example: GoogleContactsSelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN require 'DBI' cnxn = DBI.connect('DBI:ODBC:CData GoogleContacts Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Summary, StartDateTime FROM Friends") #display the names of the columns resultSet.column_names.each do |name| print name, "\t" end puts #display the results while row = resultSet.fetch do (0..resultSet.column_names.size - 1).each do |n| print row[n], "\t" end puts end resultSet.finish #close the connection cnxn.disconnect if cnxn

With the file completed, you are ready to display your Google Contacts data with Ruby. To do so, simply run your file from the command line:
