Connect to HCL Domino Data in Ruby


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

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

Create an ODBC Connection to HCL Domino 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.

Connecting to Domino

To connect to Domino data, set the following properties:

  • URL: The host name or IP of the server hosting the Domino database. Include the port of the server hosting the Domino database. For example: http://sampleserver:1234/
  • DatabaseScope: The name of a scope in the Domino Web UI. The driver exposes forms and views for the schema governed by the specified scope. In the Domino Admin UI, select the Scopes menu in the sidebar. Set this property to the name of an existing scope.

Authenticating with Domino

Domino supports authenticating via login credentials or an Azure Active Directory OAuth application:

Login Credentials

To authenticate with login credentials, set the following properties:

  • AuthScheme: Set this to "OAuthPassword"
  • User: The username of the authenticating Domino user
  • Password: The password associated with the authenticating Domino user

The driver uses the login credentials to automatically perform an OAuth token exchange.

AzureAD

This authentication method uses Azure Active Directory as an IdP to obtain a JWT token. You need to create a custom OAuth application in Azure Active Directory and configure it as an IdP. To do so, follow the instructions in the Help documentation. Then set the following properties:

  • AuthScheme: Set this to "AzureAD"
  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
  • OAuthClientId: The Client ID obtained when setting up the custom OAuth application.
  • OAuthClientSecret: The Client secret obtained when setting up the custom OAuth application.
  • CallbackURL: The redirect URI defined when you registered your app. For example: https://localhost:33333
  • AzureTenant: The Microsoft Online tenant being used to access data. Supply either a value in the form companyname.microsoft.com or the tenant ID.

    The tenant ID is the same as the directory ID shown in the Azure Portal's Azure Active Directory > Properties page.

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 HCL Domino Data

Create a new Ruby file (for example: DominoSelect.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 Domino Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Name, Address FROM ByName WHERE City = 'Miami'") #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 HCL Domino data with Ruby. To do so, simply run your file from the command line:
