Connect to Greenhouse Data in Ruby



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

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

Create an ODBC Connection to Greenhouse 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 need an API key to connect to Greenhouse. To create an API key, follow the steps below:

  1. Click the Configure icon in the navigation bar and locate Dev Center on the left.
  2. Select API Credential Management.
  3. Click Create New API Key.
    • Set "API Type" to Harvest.
    • Set "Partner" to custom.
    • Optionally, provide a description.
  4. Proceed to Manage permissions and select the appropriate permissions based on the resources you want to access through the driver.
  5. Copy the created key and set APIKey to that value.

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 Greenhouse Data

Create a new Ruby file (for example: GreenhouseSelect.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 Greenhouse Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Id, CandidateId FROM Applications WHERE Status = 'Active'") #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 Greenhouse data with Ruby. To do so, simply run your file from the command line:
